+Requirements
+------------
+
+The package swig needs to be installed and available in the PATH (http://www.swig.org/). It 
+is required by scipy and we have not decided to bundle it with VIDE at the moment.
+
+
+Quick Start Guide
+-----------------
+
+After installing the package with `python3 setup.py install --user`, you can execute
+
+```
+python3 -m void_pipeline  your_config_file.py
+```
+
+The VIDE tools are all packaged in the `vide` package. 
+
+
+
+Notes for CONDA
+---------------
+
+
+If you use a conda installation, you have to be sure to use all the building tools that 
+are consistent. On linux that means for example installing the conda packages `gcc_linux-64`
+ and `gxx_linux-64`. In addition to that it is recommended to define the environment variable 
+`LIBRARY_PATH=the_path_of_your_conda_environment_with_/lib`. For example if your environment
+is in '/home/user/conda' you should define
+
+```
+export LIBRARY_PATH=/home/user/conda/lib
+```
+
+You can then initiate the construction with
+
+```
+python3 setup.py build
+```

-                   CFITSIO Interface Library
-
-CFITSIO is a library of ANSI C routines for reading and writing FITS
-format data files.  A set of Fortran-callable wrapper routines are also
-included for the convenience of Fortran programmers.  This README file
-gives a brief summary of how to build and test CFITSIO, but the CFITSIO
-User's Guide, found in the files cfitsio.doc (plain text), cfitsio.tex
-(LaTeX source file), cfitsio.ps, or cfitsio.pdf should be
-referenced for the latest and most complete information.
-
-BUILDING CFITSIO
-----------------
-
-The CFITSIO code is contained in about 40 *.c source files and several *.h
-header files.  The CFITSIO library is built on Unix systems by typing:
-
- >  ./configure [--prefix=/target/installation/path]
- >  make          (or  'make shared')
- >  make install  (this step is optional)
-
-at the operating system prompt.  The configure command customizes the
-Makefile for the particular system, then the `make' command compiles the
-source files and builds the library.  Type `./configure' and not simply
-`configure' to ensure that the configure script in the current directory
-is run and not some other system-wide configure script.  The optional
-'prefix' argument to configure gives the path to the directory where
-the CFITSIO library and include files should be installed via the later
-'make install' command. For example,
-
-   > ./configure --prefix=/usr1/local
-
-will cause the 'make install' command to copy the CFITSIO libcfitsio file 
-to /usr1/local/lib and the necessary include files to /usr1/local/include
-(assuming of course that the  process has permission to write to these 
-directories).
-
-On VAX/VMS and ALPHA/VMS systems the make.com command file may be used
-to build the cfitsio.olb object library using the default G-floating
-point option for double variables.  The make\_dfloat.com and make\_ieee.com
-files may be used instead to build the library with the other floating
-point options.
-
-A precompiled DLL version of CFITSIO is available for IBM-PC users of
-the Borland or Microsoft Visual C++ compilers in the files
-cfitsiodll_xxxx_borland.zip and cfitsiodll_xxxx_vcc.zip, where 'xxxx'
-represents the current release number.  These zip archives also
-contains other files and instructions on how to use the CFITSIO DLL
-library. The CFITSIO library may also be built from the source code
-using the makefile.bc or makefile.vcc  files.  Finally, the makepc.bat
-file gives an example of  building CFITSIO with the Borland C++ v4.5
-compiler using simpler DOS commands.
-
-When building on Mac OS-X, users should follow the Unix instructions,
-above. Previous MacOS versions of the cfitsio library can be built by
-(1) un binhex and unstuff cfitsio_mac.sit.hqx, (2) put CFitsioPPC.mcp
-in the cfitsio directory, and (3) load CFitsioPPC.mcp into CodeWarrior
-Pro 5 and make.  This builds the cfitsio library for PPC.  There are
-also targets for both the test program and the speed test program.
-
-To use the MacOS port you can add Cfitsio PPC.lib to your Codewarrior
-Pro 5 project.  Note that this only has been tested for the PPC and
-probably won't work
- on 68k macs.
-
-TESTING CFITSIO
----------------
-
-The CFITSIO library should be tested by building and running
-the testprog.c program that is included with the release. 
-On Unix systems, type:
--
-    % make testprog
-    % testprog > testprog.lis
-    % diff testprog.lis testprog.out
-    % cmp testprog.fit testprog.std
--
- On VMS systems,
-(assuming cc is the name of the C compiler command), type:
--
-    $ cc testprog.c
-    $ link testprog, cfitsio/lib
-    $ run testprog
--
-The testprog program should produce a FITS file called `testprog.fit'
-that is identical to the testprog.std FITS file included in this
-release.  The diagnostic messages (which were piped to the file
-testprog.lis in the Unix example) should be identical to the listing
-contained in the file testprog.out.  The 'diff' and 'cmp' commands
-shown above should not report any differences in the files.
-
-USING CFITSIO
--------------
-
-The CFITSIO User's Guide, contained in the files cfitsio.doc (plain
-text file) and cfitsio.ps (postscript file), provides detailed
-documentation about how to build and use the CFITSIO library.
-It contains a description of every user-callable routine in the
-CFITSIO interface.
-
-The cookbook.c file provides some sample routines for performing common
-operations on various types of FITS files.  Programmers are urged to
-examine these routines for recommended programming practices when using
-CFITSIO.  Users are free to copy or modify these routines for their own
-purposes.
-
-SUPPORTED PLATFORMS
--------------------
-
-CFITSIO has currently been tested on the following platforms:
-
-   Operating System          Compiler
-   ----------------          --------
-  OPERATING SYSTEM           COMPILER
-   Sun OS                     gcc and cc (3.0.1)
-   Sun Solaris                gcc and cc
-   Silicon Graphics IRIX      gcc and cc
-   Silicon Graphics IRIX64    MIPS
-   Dec Alpha OSF/1            gcc and cc
-   DECstation  Ultrix         gcc
-   Dec Alpha OpenVMS          cc 
-   DEC VAX/VMS                gcc and cc
-   HP-UX                      gcc
-   IBM AIX                    gcc
-   Linux                      gcc
-   MkLinux                    DR3
-   Windows 95/98/NT           Borland C++ V4.5
-   Windows 95/98/NT/ME/XP     Microsoft/Compaq Visual C++ v5.0, v6.0
-   Windows 95/98/NT           Cygwin gcc
-   OS/2                       gcc + EMX
-   Mac OS 7.1 or greater      Metrowerks 10.+
-   Mac OS-X 10.1 or greater   cc (gcc)
-
-CFITSIO will probably run on most other Unix platforms without
-modification.  Cray supercomputers and IBM mainframe computers are
-currently not supported.
-
-Reports of any success or failure to run CFITSIO on other platforms
-would be appreciated.  Any problem reports or suggestions for
-improvements are also welcome and should be sent to the primary author.

-To build CFITSIO library on an Intel Mac as a Universal Binary
-
-Unzip the library:
-- tar xzf cfitsio3060.tar.gz (or whatever version this is)
-
-- cd cfitsio/
-
-- copy the cfitsio-xcodeproj.zip file here
-
-- unzip cfitsio-xcodeproj.zip
-
-- start Xcode and open cfitsio.xcodeproj
-
-- expand the "Targets" menu under "Groups & Files" 
-
-- choose one of the following build options:
-
-  * right-click on Build PPC -> Build "Build PPC"
-
-  * right-click on Build i386 -> Build "Build i386"
-
-  * right-click on Build x86_64 -> Build "Build x86_64"
-
-  * right-click on Build Universal -> Build "Build Universal"
-    (Builds all three of the above options, i.e. a Universal Binary
-     usable on ppc, i386, and x86_64 architectures)
-
-  (For some reason clicking on the menu "Build" icon doesn't seem to
-   work correctly, but the right-click menus do).
-
--------------------------------------------------------
-
-Another way to build the universal binary:
-
-- unpack the cfitsio source code tar file
-- cd cfitsio
-
-Set the CFLAGS environment variable for building a Universal Binary:
-
-  C-Shell variants:
-  setenv CFLAGS "-arch ppc -arch i386 -arch x86_64 -g -O2"
-
-  Bourne Shell variants:
-  export CFLAGS="-arch ppc -arch i386 -arch x86_64 -g -O2"
-
-Then proceed with the standard cfitsio build, i.e.:
-
-- ./configure
-- make
-- make install
-
-
--------------------------------------------------------
-
-Below, are the old (and now obsolete) instructions for building CFITSIO
-on classic Mac OS-9 or earlier versions:
-
-1. Un binhex and unstuff cfitsio_mac.sit.hqx
-2. put CFitsioPPC.mcp in the cfitsio directory.
-2. Load CFitsioPPC.mcp into CodeWarrior Pro 5 and make.
-   This builds the cfitsio library for PPC.  There are also targets for both 
-   the test program and the speed test program.
-
-To use the MacOS port you can add Cfitsio PPC.lib to your Codewarrior Pro 5
-project.  Note that this only has been tested for the PPC. It probably
-won't work on 68k macs.  Also note that the fortran bindings aren't
-included.  I haven't worked with the codewarrior f2c plugin so I don't know
-how these would work.  If one is interested, please write and I can look
-into this.

-     Instructions on using CFITSIO on Windows platforms for C programmers
-
-These instructions use a simple DOS-style command window. It is also possible
-to build and use CFITSIO within a GUI programming environment such as Visual
-Studio, but this is not supported here.
-
-===============================================================================
-1.  Build the CFITSIO dll library  
-
-This step will create the cfitsio.def, cfitsio.dll, and cfitsio.lib files.
-(If you downloaded the CFITSIO .zip file that contains the pre-built binary
-.dll file, then SKIP THIS STEP).
-
-  A. With Microsoft Visual C++:
-
-      1. Open a DOS command window and execute the vcvars32.bat file that 
-         is distributed with older versions of Visual C++, or simply open 
-         the Visual C++ command window (e.g., when using Visual Studio 2010).
-
-      2. Unpack the CFITSIO source files (cfitxxxx.zip) into a new empty directory
-
-      3. In the DOS command window, cd to that directory and enter the 
-         following commands:
-
-		nmake winDumpExts.mak
-		nmake makefile.vcc
-			(ignore the compiler warning messages)
-
-  B: With  Borland C++:
-
-     First, follow the instructions provided by Borland to set up
-     the proper environment variables and configure files for the compiler.
-   
-     Unpack the cfitsio.zip source file distribution into a suitable directory.
-   
-     In a DOS command window, cd to that directory and then execute the 
-     makepc.bat batch file on the command line to build the CFITSIO library, 
-     and the testprog and cookbook sample programs.
-
-===============================================================================
-2.  Test the CFITSIO library with Visual C++
-
-     Compile and link the testprog.c test program.  When using Visual Studio,
-     the command is:
-
-		cl /MD testprog.c cfitsio.lib
-
-
-     This will create the testprog.exe executable program.  Running this
-     program should print out a long series of diagnostic messages
-     that should end with "Status = 0; OK - no error"
-
-===============================================================================
-3.  Compile and link an application program that calls CFITSIO routines
-    with Visual C++
-
-	Include the fitsio.h and longnam.h header files in the C source code.
-
-	Link the program with the cfitsio.lib file:
-
-		cl /MD your_program.c cfitsio.lib
-
-
-	NOTE: The /MD command line switch must be specified on the cl
-	command line to force the compiler/linker to use the
-	appropriete runtime library.   If this switch is omitted, then
-	the fits_report_error function in CFITSIO will likely crash.  
-
-	When building programs in the Visual Studio environment, one
-	can force the equivalent of the /MD switch by selecting
-	'Settings...' under the 'Project' menu, then click on the C/C++
-	tab and select the 'Code Generator' category.  Then under 'User
-	Run-time Library' select 'Multithreaded DLL'.

-         Examples of valid extension specifiers:

-            [events]           - events extension
-            [events, 2]        - events extension, with EXTVER = 2
-            [events,2]         - spaces are optional
-            [events, 3, b]     - same as above, plus XTENSION = 'BINTABLE'
-            [PICS; colName(12)] - an image in row 12 of the colName column
-                                      in the PICS table extension             
-            [PICS; colName(exposure > 1000)] - as above, but find image in
-                          first row with with exposure column value > 1000.
-            [Rate Table] - extension name can contain spaces!
-            [Rate Table;colName(exposure>1000)]

-         Examples of other types of specifiers (Not extension specifiers)
-
-            [bin]  !!! this is ambiguous, and can't be distinguished from
-                       a valid extension specifier
-            [bini X=1:512:16]  (also binb, binj, binr, and bind are allowed)
-            [binr (X,Y) = 5]

-         There will always be some ambiguity between an extension name and 
-         a boolean row filtering expression, (as in a couple of the above
-         examples).  If there is any doubt, the expression should be treated
-         as an extension specification;  The user can always add an explicit
-         expression specifier to override this interpretation.
-
-         The following decision logic will be used:
-
-         1) locate the first token, terminated with a space, comma, 
-            semi-colon, or closing bracket.
-
-         2) the token is not part of an extension specifier if any of
-            the following is true:
-
-            - if the token begins with '@' and contains a '.'
-            - if the token contains an operator: = > < || && 
-            - if the token begins with "gtifilter(" or "regfilter(" 
-            - if the token is terminated by a space and is followed by
-               additional characters (not a ']')  AND any of the following:
-                 - the token is 'col'
-                 - the token is 3 or 4 chars long and begins with 'bin'
-                 - the second token begins with an operator:
-                     ! = < > | & + - * / %
-                 
-
-         3) otherwise, the string is assumed to be an extension specifier

-   file stream) this is not possible and an error will be returned.
-
-   4.  Else if the URL does not specify an extension (e.g. 'myfile.fits') then
-   a special extension number = -99 will be returned to signal that no
-   extension was specified.  This feature is mainly for compatibility with
-   existing FTOOLS software.  CFITSIO would open the primary array by default
-   (extension_num = 1) in this case.

-   A sequence of calls to fits_split_names will split the input string
-   into name tokens.  The string typically contains a list of file or
-   column names.  The names must be delimited by a comma and/or spaces.
-   This routine ignores spaces and commas that occur within parentheses,
-   brackets, or curly brackets.  It also strips any leading and trailing
-   blanks from the returned name.
-
-   This routine is similar to the ANSI C 'strtok' function:
-
-   The first call to fits_split_names has a non-null input string.
-   It finds the first name in the string and terminates it by
-   overwriting the next character of the string with a '\0' and returns
-   a pointer to the name.  Each subsequent call, indicated by a NULL
-   value of the input string, returns the next name, searching from
-   just past the end of the previous name.  It returns NULL when no
-   further names are found.
-
-   The following line illustrates how a string would be split into 3 names:
-    myfile[1][bin (x,y)=4], file2.fits  file3.fits
-    ^^^^^^^^^^^^^^^^^^^^^^  ^^^^^^^^^^  ^^^^^^^^^^
-      1st name               2nd name    3rd name

-         CFITSIO - An Interface to FITS Format Files for C Programmers
- 
-                    William D Pence, HEASARC, NASA/GSFC
-                               Version 3.0 
- 
- 
-[Note: This file contains various formatting command symbols ('*', '-')
-in the first column which are used when generating the LATeX version of
-this document.]
-
-*I.  Introduction
-
-**A.   A Brief Overview
- 
-CFITSIO is a machine-independent library of routines for reading and
-writing data files in the FITS (Flexible Image Transport System) data
-format.  It can also read IRAF format image files and raw binary data
-arrays by converting them on the fly into a virtual FITS format file.
-This library is written in ANSI C and provides a powerful yet simple
-interface for accessing FITS files which will run on most commonly used
-computers and workstations.  CFITSIO supports all the features
-described in the official NOST definition of the FITS format and can
-read and write all the currently defined types of extensions, including
-ASCII tables (TABLE), Binary tables (BINTABLE) and IMAGE extensions.
-The CFITSIO routines insulate the programmer from having to deal with
-the complicated formatting details in the FITS file, however, it is
-assumed that users have a general knowledge about the structure and
-usage of FITS files.
-
-CFITSIO also contains a set of Fortran callable wrapper routines which
-allow Fortran programs to call the CFITSIO routines.  See the companion
-``FITSIO User's Guide'' for the definition of the Fortran subroutine
-calling sequences.  These wrappers replace the older Fortran FITSIO
-library which is no longer supported.
-
-The CFITSIO package was initially developed by the HEASARC (High Energy
-Astrophysics Science Archive Research Center) at the NASA Goddard Space
-Flight Center to convert various existing and newly acquired
-astronomical data sets into FITS format and to further analyze data
-already in FITS format.  New features continue to be added to CFITSIO
-in large part due to contributions of ideas or actual code from
-users of the package.  The Integral Science Data Center in Switzerland,
-and the XMM/ESTEC project in The Netherlands made especially significant
-contributions that resulted in many of the new features that appeared
-in v2.0 of CFITSIO.
-
-**B.  Sources of FITS Software and Information
-
-The latest version of the CFITSIO source code,
-documentation, and example programs are available on the World-Wide
-Web or via anonymous ftp from:
--
-        http://heasarc.gsfc.nasa.gov/fitsio
-        ftp://legacy.gsfc.nasa.gov/software/fitsio/c

-
-Any questions, bug reports, or suggested enhancements related to the CFITSIO
-package should be sent to the primary author:

--
-This User's Guide assumes that readers already have a general
-understanding of the definition and structure of FITS format files.
-Further information about FITS formats is available from the FITS Support
-Office at {\tt http://fits.gsfc.nasa.gov}.  In particular, the
-'NOST FITS Standard' gives the authoritative definition of the FITS data
-format, and the  `FITS User's Guide' provides additional historical background
-and practical advice on using FITS files.
-
-The HEASARC also provides a very sophisticated FITS file analysis
-program called `Fv' which can be used to display and edit the contents
-of any FITS file as well as construct new FITS files from scratch. The
-display functions in Fv allow users to interactively adjust the
-brightness and contrast of images, pan, zoom, and blink images, and
-measure the positions and brightnesses of objects within images. FITS
-tables can be displayed like a spread sheet, and then modified using
-powerful calculator and sorting functions.  Fv is freely available for
-most Unix platforms, Mac PCs, and Windows PCs.
-CFITSIO users may also be interested in the FTOOLS package of programs
-that can be used to manipulate and analyze FITS format files.
-Fv and FTOOLS are available from their respective Web sites at:

-**C.  Acknowledgments
-
-The development of the many powerful features in CFITSIO was made
-possible through collaborations with many people or organizations from
-around the world.  The following in particular have made especially
-significant contributions:
-
-Programmers from the Integral Science Data Center, Switzerland (namely,
-Jurek Borkowski, Bruce O'Neel, and Don Jennings), designed the concept
-for the plug-in I/O drivers that was introduced with CFITSIO 2.0.  The
-use of `drivers' greatly simplified  the low-level I/O, which in turn
-made other new features in CFITSIO (e.g., support for compressed FITS
-files and support for IRAF format image files) much easier to
-implement.  Jurek Borkowski wrote the Shared Memory driver, and Bruce
-O'Neel wrote the drivers for accessing FITS files over the network
-using the FTP, HTTP, and ROOT protocols.  Also, in 2009, Bruce O'Neel
-was the key developer of the thread-safe version of CFITSIO. 
-
-The ISDC also provided the template parsing routines (written by Jurek
-Borkowski) and the hierarchical grouping routines (written by Don
-Jennings).  The ISDC DAL (Data Access Layer) routines are layered on
-top of CFITSIO and make extensive use of these features.
-
-Giuliano Taffoni and Andrea Barisani, at INAF, University of Trieste,
-Italy, implemented the I/O driver routines for accessing FITS files
-on the computational grids using the gridftp protocol.
-
-Uwe Lammers (XMM/ESA/ESTEC, The Netherlands) designed the
-high-performance lexical parsing algorithm that is used to do
-on-the-fly filtering of FITS tables.  This algorithm essentially
-pre-compiles the user-supplied selection expression into a form that
-can be rapidly evaluated for each row.  Peter Wilson (RSTX, NASA/GSFC)
-then wrote the parsing routines used by CFITSIO based on Lammers'
-design, combined with other techniques such as the CFITSIO iterator
-routine to further enhance the data processing throughput.  This effort
-also benefited from a much earlier lexical parsing routine that was
-developed by Kent Blackburn (NASA/GSFC). More recently, Craig Markwardt
-(NASA/GSFC) implemented additional functions (median, average, stddev)
-and other enhancements to the lexical parser.
-
-The CFITSIO iterator function is loosely based on similar ideas
-developed for the XMM Data Access Layer.
-
-Peter Wilson (RSTX, NASA/GSFC) wrote the complete set of
-Fortran-callable wrappers for all the CFITSIO routines, which in turn
-rely on the CFORTRAN macro developed by Burkhard Burow.
-
-The syntax used by CFITSIO for filtering or binning input FITS files is
-based on ideas developed for the AXAF Science Center Data Model by
-Jonathan McDowell, Antonella Fruscione, Aneta Siemiginowska and Bill
-Joye. See http://heasarc.gsfc.nasa.gov/docs/journal/axaf7.html for
-further description of the AXAF Data Model.
-
-The file decompression code were taken directly from the gzip (GNU zip)
-program developed by Jean-loup Gailly and others.
-
-The new compressed image data format (where the image is tiled and
-the compressed byte stream from each tile is stored in a binary table)
-was implemented in collaboration with Richard White (STScI), Perry
-Greenfield (STScI) and Doug Tody (NOAO). 
-
-Doug Mink (SAO) provided the routines for converting IRAF format 
-images into FITS format.
-
-Martin Reinecke (Max Planck Institute, Garching)) provided the modifications to 
-cfortran.h that are necessary to support 64-bit integer values when calling 
-C routines from fortran programs.  The cfortran.h macros were originally developed 
-by Burkhard Burow (CERN).
-
-Julian Taylor (ESO, Garching) provided the fast byte-swapping algorithms
-that use the SSE2 and SSSE3 machine instructions available on x86\_64 CPUs.
-
-In addition, many other people have made valuable contributions to the
-development of CFITSIO.  These include (with apologies to others that may
-have inadvertently been omitted):

-The CFITSIO code is contained in about 40 C source files (*.c) and header
-files (*.h). On VAX/VMS systems 2 assembly-code files (vmsieeed.mar and
-vmsieeer.mar) are also needed.
-

--
-CFITSIO will probably run on most other Unix platforms.  Cray
-supercomputers are currently not supported.
-
-***1.  Unix Systems
-
-The CFITSIO library is built on Unix systems by typing:
--
- >  ./configure [--prefix=/target/installation/path] [--enable-reentrant]
-                [--enable-sse2] [--enable-ssse3]
- >  make          (or  'make shared')
- >  make install  (this step is optional)
--
-at the operating system prompt.  The configure command customizes the
-Makefile for the particular system, then the `make' command compiles the
-source files and builds the library.  Type `./configure' and not simply
-`configure' to ensure that the configure script in the current directory
-is run and not some other system-wide configure script.  The optional
-'prefix' argument to configure gives the path to the directory where
-the CFITSIO library and include files should be installed via the later
-'make install' command. For example,
--
-   > ./configure --prefix=/usr1/local
--
-will cause the 'make install' command to copy the CFITSIO libcfitsio file 
-to /usr1/local/lib and the necessary include files to /usr1/local/include
-(assuming of course that the  process has permission to write to these 
-directories).
-
-The optional --enable-reentrant flag will attempt to configure CFITSIO
-so that it can be used in multi-threaded programs.  See the "Using CFITSIO in Multi-threaded Environments" section, below, for more details.
-
-The optional --enable-sse2 and --enable-ssse3 flags will cause configure to 
-attempt to build CFITSIO using faster byte-swapping algorithms.  
-See the "Optimizing Programs" chapter of this manual for
-more information about these options.
-
-The 'make shared' option builds a shared or dynamic version of the
-CFITSIO library.  When using the shared library the executable code is
-not copied into your program at link time and instead the program
-locates the necessary library code at run time, normally through
-LD\_LIBRARY\_PATH or some other method. The advantages of using a shared
-library are:
--
-   1.  Less disk space if you build more than 1 program
-   2.  Less memory if more than one copy of a program using the shared
-       library is running at the same time since the system is smart
-       enough to share copies of the shared library at run time.
-   3.  Possibly easier maintenance since a new version of the shared
-       library can be installed without relinking all the software
-       that uses it (as long as the subroutine names and calling
-       sequences remain unchanged).
-   4.  No run-time penalty.
--
-The disadvantages are:
--
-   1. More hassle at runtime.  You have to either build the programs
-      specially or have LD_LIBRARY_PATH set right.
-   2. There may be a slight start up penalty, depending on where you are
-      reading the shared library and the program from and if your CPU is
-      either really slow or really heavily loaded.
--
-
-On Mac OS X platforms the 'make shared' command works like on other
-UNIX platforms, but a .dylib file will be created instead of .so.  If
-installed in a nonstandard location, add its location to the
-DYLD\_LIBRARY\_PATH environment variable so that the library can be found
-at run time.
-
-On HP/UX systems, the environment variable CFLAGS should be set
-to -Ae before running configure to enable "extended ANSI" features.
-
-By default, a set of Fortran-callable wrapper routines are
-also built and included in the CFITSIO library.  If these wrapper
-routines are not needed (i.e., the CFITSIO library will not
-be linked to any Fortran applications which call FITSIO subroutines)
-then they may be omitted from the build by typing 'make all-nofitsio'
-instead of simply typing 'make'.  This will reduce the size
-of the CFITSIO library slightly.
-
-It may not be possible to statically link programs that use CFITSIO on
-some platforms (namely, on Solaris 2.6) due to the network drivers
-(which provide FTP and HTTP access to FITS files).  It is possible to
-make both a dynamic and a static version of the CFITSIO library, but
-network file access will not be possible using the static version. 
-
-***2.  VMS
-
-On VAX/VMS and ALPHA/VMS systems the make\_gfloat.com command file may
-be executed to build the cfitsio.olb object library using the default
-G-floating point option for double variables.  The make\_dfloat.com and
-make\_ieee.com files may be used instead to build the library with the
-other floating point options. Note that the getcwd function that is
-used in the group.c module may require that programs using CFITSIO be
-linked with the ALPHA\$LIBRARY:VAXCRTL.OLB library.  See the example
-link line in the next section of this document.
-
-***3.  Windows PCs
-
-A precompiled DLL version of CFITSIO is available for IBM-PC users of
-the Borland or Microsoft Visual C++ compilers in the files
-cfitsiodll\_3xxx\_borland.zip and cfitsiodll\_3xxx\_vcc.zip, where
-'3xxx' represents the current release number.  These zip archives also
-contains other files and instructions on how to use the CFITSIO DLL
-library.
-
-The CFITSIO library may also be built from the source code using the
-makefile.bc or makefile.vcc  files.  Finally, the makepc.bat file gives
-an example of  building CFITSIO with the Borland C++ v4.5 or v5.5  compiler
-using older DOS commands.
-
-***4.  Macintosh PCs
-
-When building on Mac OS-X, users should follow the Unix instructions,
-above.  See the README.MacOS file for instructions on building a Universal
-Binary that supports both Intel and PowerPC CPUs.
-
-**B.  Testing the Library
- 
-The CFITSIO library should be tested by building and running
-the testprog.c program that is included with the release. 
-On Unix systems, type:
--
-    % make testprog
-    % testprog > testprog.lis
-    % diff testprog.lis testprog.out
-    % cmp testprog.fit testprog.std
--
- On VMS systems,
-(assuming cc is the name of the C compiler command), type:
--
-    $ cc testprog.c
-    $ link testprog, cfitsio/lib, alpha$library:vaxcrtl/lib
-    $ run testprog
--
-The test program should produce a FITS file called `testprog.fit'
-that is identical to the `testprog.std' FITS file included with this
-release.  The diagnostic messages (which were piped to the file
-testprog.lis in the Unix example) should be identical to the listing
-contained in the file testprog.out.  The 'diff' and 'cmp' commands
-shown above should not report any differences in the files.  (There
-may be some minor format differences, such as the presence or
-absence of leading zeros, or 3 digit exponents in numbers, 
-which can be ignored).
-
-The Fortran wrappers in CFITSIO may be tested with the testf77
-program on Unix systems with:
--
-    % f77 -o testf77 testf77.f -L. -lcfitsio -lnsl -lsocket    
-  or
-    % f77 -f -o testf77 testf77.f -L. -lcfitsio    (under SUN O/S)
-  or
-    % f77 -o testf77 testf77.f -Wl,-L. -lcfitsio -lm -lnsl -lsocket (HP/UX)
-
-    % testf77 > testf77.lis
-    % diff testf77.lis testf77.out
-    % cmp testf77.fit testf77.std
--
-On machines running SUN O/S, Fortran programs must be compiled with the
-'-f' option to force double precision variables to be aligned on 8-byte
-boundarys to make the fortran-declared variables compatible with C.  A
-similar compiler option may be required on other platforms.  Failing to
-use this option may cause the program to crash on FITSIO routines that
-read or write double precision variables.  
-
-Also note that on some systems, the output listing of the testf77
-program may differ slightly from the testf77.std template, if leading
-zeros are not printed by default before the decimal point when using F
-format.
-
-A few other utility programs are included with CFITSIO; the first four
-of this programs can be compiled an linked by typing `make
-program\_name' where `program\_name' is the actual name of the program:
--
-    speed - measures the maximum throughput (in MB per second)
-              for writing and reading FITS files with CFITSIO.
-
-    listhead - lists all the header keywords in any FITS file
-
-    fitscopy - copies any FITS file (especially useful in conjunction
-                 with the CFITSIO's extended input filename syntax).
-
-    cookbook - a sample program that performs common read and
-                 write operations on a FITS file.
-
-    iter_a, iter_b, iter_c - examples of the CFITSIO iterator routine
--
-
-**C.  Linking Programs with CFITSIO
-
-When linking applications software with the CFITSIO library, several
-system libraries usually need to be specified on the link command
-line.  On Unix systems, the most reliable way to determine what
-libraries are required is to type 'make testprog' and see what
-libraries the configure script has added.  The typical libraries that
-need to be added are -lm (the math library) and -lnsl and -lsocket
-(needed only for FTP and HTTP file access).  These latter 2 libraries
-are not needed on VMS and Windows platforms, because FTP file access is
-not currently supported on those platforms.
-
-Note that when upgrading to a newer version of CFITSIO it is usually
-necessary to recompile, as well as relink, the programs that use CFITSIO,
-because the definitions in fitsio.h often change.
- 
-**D.  Using CFITSIO in Multi-threaded Environments
-
-CFITSIO can be used either with the
-POSIX pthreads interface or the OpenMP interface for multi-threaded
-parallel programs.  When used in a multi-threaded environment, 
-the CFITSIO library *must* be built using 
-the -D\_REENTRANT compiler directive.  This can be done using the following
-build commands:
--
-  >./configure --enable-reentrant
-  > make
--
-A function called fits\_is\_reentrant is available to test 
-whether or not CFITSIO was compiled with the -D\_REENTRANT
-directive.  When this feature is enabled, multiple threads can 
-call any of the CFITSIO routines 
-to simultaneously read or write separate 
-FITS files.  Multiple threads can also read data from
-the same FITS file simultaneously, as long as the file
-was opened independently by each thread.  This relies on
-the operating system to correctly deal with reading the
-same file by multiple processes.  Different threads should
-not share the same 'fitsfile' pointer to read an opened
-FITS file, unless locks are placed around the calls to 
-the CFITSIO reading routines.  
-Different threads should never try to write to the same
-FITS file.
-
-**E.  Getting Started with CFITSIO
-
-In order to effectively use the CFITSIO library it is recommended that
-new users begin by reading the ``CFITSIO Quick Start Guide''.  It
-contains all the basic information needed to write programs that
-perform most types of operations on FITS files.  The set of example
-FITS utility programs that are available from the CFITSIO web site are
-also very useful for learning how to use CFITSIO.  To learn even more
-about the capabilities of the CFITSIO library the following steps are
-recommended:
-
-1.  Read the following short `FITS Primer' chapter for an overview of
-the structure of FITS files.
-
-2. Review the Programming Guidelines in Chapter 4 to become familiar
-with the conventions used by the CFITSIO interface.
-
-3.  Refer to the cookbook.c, listhead.c, and fitscopy.c programs that
-are included with this release for examples of routines that perform
-various common FITS file operations.  Type 'make program\_name' to
-compile and link these programs on Unix systems.
-
-4.  Write a simple program to read or write a FITS file using the Basic
-Interface routines described in Chapter 5.
-
-5.  Scan through the more specialized routines that are described in
-the following chapters to become familiar with the functionality that
-they provide.
-
-**F.  Example Program
-
-The following listing shows an example of how to use the CFITSIO
-routines in a C program.    Refer to the cookbook.c program that is

-*III.  A FITS Primer
-
-This section gives a brief overview of the structure of FITS files.
-Users should refer to the documentation available from the NOST, as
-described in the introduction, for more detailed information on FITS
-formats.
-
-FITS was first developed in the late 1970's as a standard data
-interchange format between various astronomical observatories.  Since
-then FITS has become the standard data format supported by most
-astronomical data analysis software packages.  
-
-A FITS file consists of one or more Header + Data Units (HDUs), where
-the first HDU is called the `Primary HDU', or `Primary Array'.  The
-primary array contains an N-dimensional array of pixels, such as a 1-D
-spectrum, a 2-D image, or a 3-D data cube.  Six different primary
-data types are supported: Unsigned 8-bit bytes, 16-bit, 32-bit, and 64-bit signed
-integers, and 32 and 64-bit floating point reals.  FITS also has a
-convention for storing 16 and 32-bit unsigned integers (see the later
-section entitled `Unsigned Integers' for more details). The primary HDU
-may also consist of only a header with a null array containing no
-data pixels.
-
-Any number of additional HDUs may follow the primary array; these
-additional HDUs are called FITS `extensions'.  There are currently 3
-types of extensions defined by the FITS standard:
-
-\begin{itemize}
-\item
-  Image Extension - a N-dimensional array of pixels, like in a primary array
-\item
-  ASCII Table Extension - rows and columns of data in ASCII character format
-\item
-  Binary Table Extension - rows and columns of data in binary representation
-\end{itemize}
-
-In each case the HDU consists of an ASCII Header Unit followed by an optional
-Data Unit.  For historical reasons, each Header or Data unit must be an
-exact multiple of 2880 8-bit bytes long.  Any unused space is padded
-with fill characters (ASCII blanks or zeros).
-
-Each Header Unit consists of any number of 80-character keyword records
-or `card images' which have the
-general form:
--
-  KEYNAME = value / comment string
-  NULLKEY =       / comment: This keyword has no value
--
-The keyword names may be up to 8 characters long and can only contain
-uppercase letters, the digits 0-9, the hyphen, and the underscore
-character. The keyword name is (usually) followed by an equals sign and
-a space character (= ) in columns 9 - 10 of the record, followed by the
-value of the keyword which may be either an integer, a floating point
-number, a character string (enclosed in single quotes), or a boolean
-value (the letter T or F).   A keyword may also have a null or undefined
-value if there is no specified value string, as in the second example, above
-
-The last keyword in the header is always the `END' keyword which has no
-value or comment fields. There are many rules governing the exact
-format of a keyword record (see the NOST FITS Standard) so it is better
-to rely on standard interface software like CFITSIO to correctly
-construct or to parse the keyword records rather than try to deal
-directly with the raw FITS formats.
-
-Each Header Unit begins with a series of required keywords which depend
-on the type of HDU.  These required keywords specify the size and
-format of the following Data Unit.  The header may contain other
-optional keywords to describe other aspects of the data, such as the
-units or scaling values.  Other COMMENT or HISTORY keywords are also
-frequently added to further document the data file.
-
-The optional Data Unit immediately follows the last 2880-byte block in
-the Header Unit.  Some HDUs do not have a Data Unit and only consist of
-the Header Unit.
-
-If there is more than one HDU in the FITS file, then the Header Unit of
-the next HDU immediately follows the last 2880-byte block of the
-previous Data Unit (or Header Unit if there is no Data Unit).
-
-The main required keywords in FITS primary arrays or image extensions are:
-\begin{itemize}
-\item
-BITPIX -- defines the data type of the array: 8, 16, 32, 64, -32, -64 for
-unsigned 8--bit byte, 16--bit signed integer, 32--bit signed integer,
-32--bit IEEE floating point, and 64--bit IEEE double precision floating
-point, respectively.
-\item
-NAXIS --  the number of dimensions in the array, usually 0, 1, 2, 3, or 4.
-\item
-NAXISn -- (n ranges from 1 to NAXIS) defines the size of each dimension.
-\end{itemize}
-
-FITS tables start with the keyword XTENSION = `TABLE' (for ASCII
-tables) or XTENSION = `BINTABLE' (for binary tables) and have the
-following main keywords:
-\begin{itemize}
-\item
-TFIELDS -- number of fields or columns in the table
-\item
-NAXIS2 -- number of rows in the table
-\item
-TTYPEn -- for each column (n ranges from 1 to TFIELDS) gives the
-name of the column
-\item
-TFORMn -- the data type of the column
-\item
-TUNITn -- the physical units of the column (optional)
-\end{itemize}

-for further information about the FITS format and related software 
-packages.

-*IV.  Programming Guidelines
-
-**A.  CFITSIO Definitions
-
-Any program that uses the CFITSIO interface must include the fitsio.h
-header file with the statement
--
-  #include "fitsio.h"
--
-This header file contains the prototypes for all the CFITSIO user
-interface routines as well as the definitions of various constants used
-in the interface.  It also defines a C structure of type `fitsfile'
-that is used by CFITSIO to store the relevant parameters that define
-the format of a particular FITS file.  Application programs must define
-a pointer to this structure for each FITS file that is to be opened.
-This structure is initialized (i.e., memory is allocated for the
-structure) when the FITS file is first opened or created with the
-fits\_open\_file or fits\_create\_file routines.  This fitsfile pointer
-is then passed as the first argument to every other CFITSIO routine
-that operates on the FITS file.  Application programs must not directly
-read or write elements in this fitsfile structure because the
-definition of the structure may change in future versions of CFITSIO.
-
-A number of symbolic constants are also defined in fitsio.h for the
-convenience of application programmers.  Use of these symbolic
-constants rather than the actual numeric value will help to make the
-source code more readable and easier for others to understand.
--
-String Lengths, for use when allocating character arrays:
-
-  #define FLEN_FILENAME 1025 /* max length of a filename                  */
-  #define FLEN_KEYWORD   72  /* max length of a keyword                   */
-  #define FLEN_CARD      81  /* max length of a FITS header card          */
-  #define FLEN_VALUE     71  /* max length of a keyword value string      */
-  #define FLEN_COMMENT   73  /* max length of a keyword comment string    */
-  #define FLEN_ERRMSG    81  /* max length of a CFITSIO error message     */
-  #define FLEN_STATUS    31  /* max length of a CFITSIO status text string */
-
-  Note that FLEN_KEYWORD is longer than the nominal 8-character keyword
-  name length because the HIERARCH convention supports longer keyword names.
- 
-Access modes when opening a FITS file:
-
-  #define READONLY  0
-  #define READWRITE 1
- 
-BITPIX data type code values for FITS images:
-
-  #define BYTE_IMG      8  /*  8-bit unsigned integers */
-  #define SHORT_IMG    16  /* 16-bit   signed integers */
-  #define LONG_IMG     32  /* 32-bit   signed integers */
-  #define LONGLONG_IMG 64  /* 64-bit   signed integers */
-  #define FLOAT_IMG   -32  /* 32-bit single precision floating point */
-  #define DOUBLE_IMG  -64  /* 64-bit double precision floating point */
-
-  The following 4 data type codes are also supported by CFITSIO:
-  #define SBYTE_IMG  10   /*  8-bit signed integers, equivalent to */
-                          /*  BITPIX = 8, BSCALE = 1, BZERO = -128 */
-  #define USHORT_IMG  20  /* 16-bit unsigned integers, equivalent to */
-                          /*  BITPIX = 16, BSCALE = 1, BZERO = 32768 */
-  #define ULONG_IMG   40  /* 32-bit unsigned integers, equivalent to */
-                          /*  BITPIX = 32, BSCALE = 1, BZERO = 2147483648 */
-
-Codes for the data type of binary table columns and/or for the
-data type of variables when reading or writing keywords or data:
-
-                              DATATYPE               TFORM CODE
-  #define TBIT          1  /*                            'X' */
-  #define TBYTE        11  /* 8-bit unsigned byte,       'B' */
-  #define TLOGICAL     14  /* logicals (int for keywords     */
-                           /*  and char for table cols   'L' */
-  #define TSTRING      16  /* ASCII string,              'A' */
-  #define TSHORT       21  /* signed short,              'I' */
-  #define TLONG        41  /* signed long,                   */
-  #define TLONGLONG    81  /* 64-bit long signed integer 'K' */
-  #define TFLOAT       42  /* single precision float,    'E' */
-  #define TDOUBLE      82  /* double precision float,    'D' */
-  #define TCOMPLEX     83  /* complex (pair of floats)   'C' */
-  #define TDBLCOMPLEX 163  /* double complex (2 doubles) 'M' */
-
-  The following data type codes are also supported by CFITSIO:
-  #define TINT         31  /* int                            */
-  #define TSBYTE       12  /* 8-bit signed byte,         'S' */
-  #define TUINT        30  /* unsigned int               'V' */
-  #define TUSHORT      20  /* unsigned short             'U'  */
-  #define TULONG       40  /* unsigned long                  */
-
-  The following data type code is only for use with fits\_get\_coltype
-  #define TINT32BIT    41  /* signed 32-bit int,         'J' */
-
-
-HDU type code values (value returned when moving to new HDU):
-
-  #define IMAGE_HDU  0  /* Primary Array or IMAGE HDU */
-  #define ASCII_TBL  1  /* ASCII  table HDU */
-  #define BINARY_TBL 2  /* Binary table HDU */
-  #define ANY_HDU   -1  /* matches any type of HDU */
- 
-Column name and string matching case-sensitivity:

-**B.  Current Header Data Unit (CHDU)
-
-The concept of the Current Header and Data Unit, or CHDU, is
-fundamental to the use of the CFITSIO library.  A simple FITS image may
-only contain a single Header and Data unit (HDU), but in general FITS
-files can contain multiple Header Data Units (also known as
-`extensions'), concatenated one after the other in the file.  The user
-can specify which HDU should be initially opened at run time by giving
-the HDU name or number after the root file name.  For example,
-'myfile.fits[4]' opens the 5th HDU in the file (note that the numbering
-starts with 0), and 'myfile.fits[EVENTS] opens the HDU with the name
-'EVENTS' (as defined by the EXTNAME or HDUNAME keywords).  If no HDU is
-specified then CFITSIO opens the first HDU (the primary array) by
-default.  The CFITSIO routines which read and write data  only operate
-within the opened HDU,  Other CFITSIO routines are provided to move to
-and open any other existing HDU within the FITS file or to append or
-insert new HDUs in the FITS file.
-
-**C.  Function Names and Variable Datatypes
-
-Most of the CFITSIO routines have both a short name as well as a
-longer descriptive name.  The short name is only 5 or 6 characters long
-and is similar to the subroutine name in the Fortran-77 version of
-FITSIO.  The longer name is more descriptive and it is recommended that
-it be used instead of the short name to more clearly document the
-source code.
-
-Many of the CFITSIO routines come in families which differ only in the
-data type of the associated parameter(s).  The data type of these
-routines is indicated by the suffix of the routine name.  The short
-routine names have a 1 or 2 character suffix (e.g., 'j' in 'ffpkyj')
-while the long routine names have a 4 character or longer suffix
-as shown in the following table:
--
-    Long      Short  Data
-    Names     Names  Type
-    -----     -----  ----
-    _bit        x    bit
-    _byt        b    unsigned byte
-    _sbyt       sb   signed byte
-    _sht        i    short integer
-    _lng        j    long integer
-    _lnglng     jj   8-byte LONGLONG integer (see note below)
-    _usht       ui   unsigned short integer
-    _ulng       uj   unsigned long integer
-    _uint       uk   unsigned int integer
-    _int        k    int integer
-    _flt        e    real exponential floating point (float)
-    _fixflt     f    real fixed-decimal format floating point (float)
-    _dbl        d    double precision real floating-point (double)
-    _fixdbl     g    double precision fixed-format floating point (double)
-    _cmp        c    complex reals (pairs of float values)
-    _fixcmp     fc   complex reals, fixed-format floating point
-    _dblcmp     m    double precision complex (pairs of double values)
-    _fixdblcmp  fm   double precision complex, fixed-format floating point
-    _log        l    logical (int)
-    _str        s    character string
--
-
-The logical data type corresponds to `int' for logical keyword values,
-and `byte' for logical binary table columns.  In other words, the value
-when writing a logical keyword must be stored in an `int' variable, and
-must be stored in a `char' array when reading or writing to `L' columns
-in a binary table.  Implicit data type conversion is not supported for
-logical table columns, but is for keywords, so a logical keyword may be
-read and cast to any numerical data type; a returned value = 0
-indicates false, and any other value = true.
-
-The `int' data type may be 2 bytes long on some old PC compilers,
-but otherwise it is nearly always 4 bytes long.   Some 64-bit
-machines, like the Alpha/OSF, define the `short', `int',
-and `long' integer data types to be 2, 4, and 8 bytes long,
-respectively. 
-
-Because there is no universal C compiler standard for the name of the
-8-byte integer datatype, the fitsio.h include file typedef's 
-'LONGLONG'  to be equivalent to  an
-appropriate 8-byte integer data type on each supported platform.
-For maximum software portability it is recommended that 
-this LONGLONG datatype be used to define 8-byte integer variables 
-rather than using the native data type name on a particular
-platform. On most
-32-bit Unix and Mac OS-X operating systems LONGLONG is equivalent to the
-intrinsic 'long long' 8-byte integer datatype.  On 64-bit systems (which currently 
-includes Alpha OSF/1, 64-bit Sun Solaris, 64-bit SGI MIPS, and  64-bit
-Itanium and Opteron PC systems), LONGLONG is  simply typedef'ed to be
-equivalent to 'long'.   Microsoft Visual C++ Version 6.0 does not define
-a 'long long'  data type, so LONGLONG is typedef'ed to be equivalent to
-the '\_\_int64' data type on 32-bit windows systems when using Visual C++.
-
-A related issue that affects the portability of software is how to print
-out the value of a 'LONGLONG' variable with printf.  Developers may
-find it convenient to use the following preprocessing statements
-in their C programs to handle this in a machine-portable manner:
-
--
-#if defined(_MSC_VER) /* Microsoft Visual C++ */
-          printf("%I64d", longlongvalue);
-	  
-#elif (USE_LL_SUFFIX == 1)
-          printf("%lld", longlongvalue);
-	  
-#else
-          printf("%ld", longlongvalue);
-#endif
--
-
-Similarly, the name of the C utility routine that converts a character
-string of digits into a 8-byte integer value is platform dependent:
-
--
-#if defined(_MSC_VER) /* Microsoft Visual C++ */
-      /* VC++ 6.0 does not seem to have an 8-byte conversion routine */
-	   
-#elif (USE_LL_SUFFIX == 1)
-          longlongvalue = atoll(*string);
-	  
-#else
-          longlongvalue = atol(*string); 
-#endif
--
-
-When dealing with the FITS byte data type it is important to remember
-that the raw values (before any scaling by the BSCALE and BZERO, or
-TSCALn and TZEROn keyword values) in byte arrays (BITPIX = 8) or byte
-columns (TFORMn = 'B') are interpreted as unsigned bytes with values
-ranging from 0 to 255.  Some C compilers define a 'char' variable as
-signed, so it is important to explicitly declare a numeric char
-variable as 'unsigned char' to avoid any ambiguity
-
-One feature of the CFITSIO routines is that they can operate on a `X'
-(bit) column in a binary table as though it were a `B' (byte) column.
-For example a `11X' data type column can be interpreted the same as a
-`2B' column (i.e., 2 unsigned 8-bit bytes).  In some instances, it can
-be more efficient to read and write whole bytes at a time, rather than
-reading or writing each individual bit.
-
-The complex and double precision complex data types are not directly
-supported in ANSI C so these data types should be interpreted as pairs
-of float or double values, respectively, where the first  value in each
-pair is the real part, and the second is the imaginary part.
-
-**D.  Support for Unsigned Integers and Signed Bytes
-
-Although FITS does not directly support unsigned integers as one of its
-fundamental data types, FITS can still be used to efficiently store
-unsigned integer data values in images and binary tables.  The
-convention used in FITS files is to store the unsigned integers as
-signed integers with an associated offset (specified by the BZERO or
-TZEROn keyword).  For example, to store unsigned 16-bit integer values
-in a FITS image the image would be defined as a signed 16-bit integer
-(with BITPIX keyword = SHORT\_IMG = 16) with the keywords BSCALE = 1.0
-and BZERO = 32768.  Thus the unsigned values of 0, 32768, and 65535,
-for example, are physically stored in the FITS image as -32768, 0, and
-32767, respectively;  CFITSIO automatically adds the BZERO offset to
-these values when they are read.  Similarly, in the case of unsigned
-32-bit integers the BITPIX keyword would be equal to LONG\_IMG = 32 and
-BZERO would be equal to 2147483648 (i.e. 2 raised to the 31st power).
-
-The CFITSIO interface routines will efficiently and transparently apply
-the appropriate offset in these cases so in general application
-programs do not need to be concerned with how the unsigned values are
-actually stored in the FITS file.  As a convenience for users, CFITSIO
-has several predefined constants for the value of BITPIX  (USHORT\_IMG,
-ULONG\_IMG) and for the TFORMn value in the case of binary tables (`U'
-and `V') which programmers can use when creating FITS files containing
-unsigned integer values.  The following code fragment illustrates how
-to write a FITS 1-D primary array of unsigned 16-bit integers:
--
-      unsigned short uarray[100];
-      int naxis, status;
-      long naxes[10], group, firstelem, nelements;
-       ...
-      status = 0;
-      naxis = 1;
-      naxes[0] = 100;
-      fits_create_img(fptr, USHORT_IMG, naxis, naxes, &status);
-
-      firstelem = 1;
-      nelements = 100;
-      fits_write_img(fptr, TUSHORT, firstelem, nelements,
-                          uarray, &status);
-       ...
--
-In the above example, the 2nd parameter in fits\_create\_img tells
-CFITSIO to write the header keywords appropriate for an array of 16-bit
-unsigned integers (i.e., BITPIX = 16 and BZERO = 32768).  Then the
-fits\_write\_img routine writes the array of unsigned short integers
-(uarray) into the primary array of the FITS file.  Similarly, a 32-bit
-unsigned integer image may be created by setting the second parameter
-in fits\_create\_img equal to `ULONG\_IMG' and by calling the
-fits\_write\_img routine with the second parameter = TULONG to write
-the array of unsigned long image pixel values.
-
-An analogous set of routines are available for reading or writing unsigned
-integer values and signed byte values in a FITS binary table extension.
-When specifying the TFORMn keyword value which defines the format of a
-column, CFITSIO recognized 3 additional data type codes besides those
-already defined in the FITS standard: `U' meaning a 16-bit unsigned
-integer column, `V' for a 32-bit unsigned integer column, and 'S'
-for a signed byte column.  These non-standard data type codes are not
-actually written into the FITS file but instead are just used internally
-within CFITSIO.  The following code fragment illustrates how to use
-these features:
--
-      unsigned short uarray[100];
-      unsigned int  varray[100];
-
-      int colnum, tfields, status;
-      long nrows, firstrow, firstelem, nelements, pcount;
-
-      char extname[] = "Test_table";           /* extension name */
-
-      /* define the name, data type, and physical units for the 2 columns */
-      char *ttype[] = { "Col_1", "Col_2", "Col_3" };

-              nelements, varray, &status);
-       ...
--
-Note that the non-standard TFORM values for the 3 columns, `U' and `V',
-tell CFITSIO to write the keywords appropriate for unsigned 16-bit and
-unsigned 32-bit integers, respectively (i.e., TFORMn = '1I' and TZEROn
-= 32678 for unsigned 16-bit integers, and TFORMn = '1J' and TZEROn =
-2147483648 for unsigned 32-bit integers).  The 'S' TFORMn value tells
-CFITSIO to write the keywords appropriate for a signed 8-bit byte column
-with TFORMn = '1B' and TZEROn = -128.  The calls to fits\_write\_col
-then write the arrays of unsigned integer values to the columns.
-
-**E.  Dealing with Character Strings
-
-The character string values in a FITS header or in an ASCII column in a
-FITS table extension are generally padded out with non-significant
-space characters (ASCII 32) to fill up the header record or the column
-width.  When reading a FITS string value, the CFITSIO routines will
-strip off these non-significant trailing spaces and will return a
-null-terminated string value containing only the significant
-characters.  Leading spaces in a FITS string are considered
-significant.  If the string contains all blanks, then CFITSIO will
-return a single blank character, i.e, the first blank is considered to
-be significant, since it distinguishes the string from a null or
-undefined string, but the remaining trailing spaces are not
-significant.
-
-Similarly, when writing string values to a FITS file the
-CFITSIO routines expect to get a null-terminated string as input;
-CFITSIO will pad the string with blanks if necessary when writing it
-to the FITS file.  
-
-When calling CFITSIO routines that return a character string it is
-vital that the size of the char array be large enough to hold the
-entire string of characters, otherwise CFITSIO will overwrite whatever
-memory locations follow the char array, possibly causing the program to
-execute incorrectly.  This type of error can be difficult to debug, so
-programmers should always ensure that the char arrays are allocated
-enough space to hold the longest possible string, {\bf including} the
-terminating NULL character.  The fitsio.h file contains the following
-defined constants which programmers are strongly encouraged to use
-whenever they are allocating space for char arrays:
--
-#define FLEN_FILENAME 1025 /* max length of a filename */
-#define FLEN_KEYWORD   72  /* max length of a keyword  */
-#define FLEN_CARD      81  /* length of a FITS header card */
-#define FLEN_VALUE     71  /* max length of a keyword value string */
-#define FLEN_COMMENT   73  /* max length of a keyword comment string */
-#define FLEN_ERRMSG    81  /* max length of a CFITSIO error message */ 
-#define FLEN_STATUS    31  /* max length of a CFITSIO status text string */ 
--
-For example, when declaring a char array to hold the value string
-of FITS keyword, use the following statement:
--
-    char value[FLEN_VALUE];
--
-Note that FLEN\_KEYWORD is longer than needed for the nominal 8-character
-keyword name because the HIERARCH convention supports longer keyword names.
- 
-**F.  Implicit Data Type Conversion
- 
-The CFITSIO routines that read and write numerical data can perform
-implicit data type conversion.  This means that the data type of the
-variable or array in the program does not need to be the same as the
-data type of the value in the FITS file.  Data type conversion is
-supported for numerical and string data types (if the string contains a
-valid number enclosed in quotes) when reading a FITS header keyword
-value and for numeric values when reading or writing values in the
-primary array or a table column.  CFITSIO returns status =
-NUM\_OVERFLOW  if the converted data value exceeds the range of the
-output data type.  Implicit data type conversion is not supported
-within binary tables for string, logical, complex, or double complex
-data types.
-
-In addition, any table column may be read as if it contained string values.
-In the case of numeric columns the returned string will be formatted
-using the TDISPn display format if it exists.
-
-**G.  Data Scaling
- 
-When reading numerical data values in the primary array or a
-table column, the values will be scaled automatically by the BSCALE and
-BZERO (or TSCALn and TZEROn) header values if they are
-present in the header.  The scaled data that is returned to the reading
-program will have
--
-        output value = (FITS value) * BSCALE + BZERO
--
-(a corresponding formula using TSCALn and TZEROn is used when reading
-from table columns).  In the case of integer output values the floating
-point scaled value is truncated to an integer (not rounded to the
-nearest integer).  The fits\_set\_bscale and fits\_set\_tscale routines
-(described in the `Advanced' chapter) may be used to override the
-scaling parameters defined in the header (e.g., to turn off the scaling
-so that the program can read the raw unscaled values from the FITS
-file).
-
-When writing numerical data to the primary array or to a table column
-the data values will generally be automatically inversely scaled by the
-value of the BSCALE and BZERO (or TSCALn and TZEROn) keyword values if
-they they exist in the header.  These keywords must have been written
-to the header before any data is written for them to have any immediate
-effect.  One may also use the fits\_set\_bscale and fits\_set\_tscale
-routines to define or override the scaling keywords in the header
-(e.g., to turn off the scaling so that the program can write the raw
-unscaled values into the FITS file). If scaling is performed, the
-inverse scaled output value that is written into the FITS file will
-have
--
-         FITS value = ((input value) - BZERO) / BSCALE
--
-(a corresponding formula using TSCALn and TZEROn is used when
-writing to table columns).  Rounding to the nearest integer, rather
-than truncation, is performed when writing integer data types to the
-FITS file.
- 
-**H.  Support for IEEE Special Values
- 
-The ANSI/IEEE-754 floating-point number standard defines certain
-special values that are used to represent such quantities as
-Not-a-Number (NaN), denormalized, underflow, overflow, and infinity.
-(See the Appendix in the NOST FITS standard or the NOST FITS User's
-Guide for a list of these values).  The CFITSIO routines that read
-floating point data in FITS files recognize these IEEE special values
-and by default interpret the overflow and infinity values as being
-equivalent to a NaN, and convert the underflow and denormalized values
-into zeros.  In some cases programmers may want access to the raw IEEE
-values, without any modification by CFITSIO.  This can be done by
-calling the fits\_read\_img or fits\_read\_col routines while
-specifying 0.0 as the value of the NULLVAL parameter.  This will force
-CFITSIO to simply pass the IEEE values through to the application
-program without any modification.  This is not fully supported on
-VAX/VMS machines, however, where there is no easy way to bypass the
-default interpretation of the IEEE special values.  This is also not 
-supported when reading floating-point images that have been compressed
-with the FITS tiled image compression convention that is discussed in
-section 5.6;  the pixels values in tile compressed images are
-represented by scaled integers, and a reserved integer value 
-(not a NaN) is used to represent undefined pixels.
-
-**I.  Error Status Values and the Error Message Stack
-
-Nearly all the CFITSIO routines return an error status value
-in 2 ways: as the value of the last parameter in the function call,
-and as the returned value of the function itself.  This provides
-some flexibility in the way programmers can test if an error
-occurred, as illustrated in the following 2 code fragments:
--
-    if ( fits_write_record(fptr, card, &status) )
-         printf(" Error occurred while writing keyword.");
-
-or,
-
-    fits_write_record(fptr, card, &status);
-    if ( status )
-         printf(" Error occurred while writing keyword.");
--
-A listing of all the CFITSIO status code values is given at the end of
-this document.  Programmers are encouraged to use the symbolic
-mnemonics (defined in fitsio.h) rather than the actual integer status
-values to improve the readability of their code.
-
-The CFITSIO library uses an `inherited status' convention for the
-status parameter which means that if a routine is called with a
-positive input value of the status parameter as input, then the routine
-will exit immediately without changing the value of the status
-parameter.  Thus, if one passes the status value returned from each
-CFITSIO routine as input to the next CFITSIO routine, then whenever an
-error is detected all further CFITSIO processing will cease.  This
-convention can simplify the error checking in application programs
-because it is not necessary to check the value of the status parameter
-after every single CFITSIO routine call.  If a program contains a
-sequence of several CFITSIO calls, one can just check the status value
-after the last call.  Since the returned status values are generally
-distinctive, it should be possible to determine which routine
-originally returned the error status.
-
-CFITSIO also maintains an internal stack of error messages
-(80-character maximum length)  which in many cases provide a more
-detailed explanation of the cause of the error than is provided by the
-error status number alone.  It is recommended that the error message
-stack be printed out whenever a program detects a CFITSIO error.  The
-function fits\_report\_error will print out the entire error message
-stack, or alternatively one may call fits\_read\_errmsg to get the
-error messages one at a time.
-
-**J.  Variable-Length Arrays in Binary Tables
- 
-CFITSIO provides easy-to-use support for reading and writing data in
-variable length fields of a binary table. The variable length columns
-have TFORMn keyword values of the form `1Pt(len)' where `t' is the
-data type code (e.g., I, J, E, D, etc.) and `len' is an integer
-specifying the maximum length of the vector in the table.  (CFITSIO also
-supports the experimental 'Q' datatype, which is identical to the 'P' type
-except that is supports is a 64-bit address space and hence much larger
-data structures).  If the value
-of `len' is not specified when the table is created (e.g., if the TFORM
-keyword value is simply specified as '1PE' instead of '1PE(400) ), then
-CFITSIO will automatically scan the table when it is closed to
-determine the maximum length of the vector and will append this value
-to the TFORMn value.
-
-The same routines that read and write data in an ordinary fixed length
-binary table extension are also used for variable length fields,
-however, the routine parameters take on a slightly different
-interpretation as described below.
-
-All the data in a variable length field is written into an area called
-the `heap' which follows the main fixed-length FITS binary table. The
-size of the heap, in bytes, is specified by the PCOUNT keyword in the
-FITS header. When creating a new binary table, the initial value of
-PCOUNT should usually be set to zero. CFITSIO will recompute the size
-of the heap as the data is written and will automatically update the
-PCOUNT keyword value when the table is closed.  When writing variable
-length data to a table, CFITSIO will automatically extend the size
-of the heap area if necessary, so that any following HDUs do not
-get overwritten.
-
-By default the heap data area starts immediately after the last row of
-the fixed-length table.  This default starting location may be
-overridden by the THEAP keyword, but this is not recommended.  
-If additional rows of data are added to the table, CFITSIO will
-automatically shift the the heap down to make room for the new
-rows, but it is obviously be more efficient to initially
-create the table with the necessary number of blank rows, so that
-the heap does not needed to be constantly moved.
-
-When writing row of data to a variable length field the entire array of values for
-a given row of the table must be written with a single call to
-fits\_write\_col. 
-The total length of the array is given by nelements
-+ firstelem - 1.  Additional elements cannot be appended to an existing
-vector at a later time since any attempt to do so will simply overwrite
-all the previously written data and the new data will be
-written to a new area of the heap.  The fits\_compress\_heap routine
-is provided to compress the heap and recover any unused space.
-To avoid having to deal with this issue, it is recommended
-that rows in a variable length field should only be written once.  
-An exception to
-this general rule occurs when setting elements of an array as
-undefined.  It is allowed to first write a dummy value into the array with
-fits\_write\_col, and then call fits\_write\_col\_nul to flag the
-desired elements as undefined. Note that the rows of a table,
-whether fixed or variable length, do not have to be written
-consecutively and may be written in any order.
-
-When writing to a variable length ASCII character field (e.g., TFORM =
-'1PA') only a single character string can be written.  The `firstelem'
-and `nelements' parameter values in the fits\_write\_col routine are
-ignored and the number of characters to write is simply determined by
-the length of the input null-terminated character string.
-
-The fits\_write\_descript routine is useful in situations where
-multiple rows of a variable length column have the identical array of
-values.  One can simply write the array once for the first row, and
-then use fits\_write\_descript to write the same descriptor values into
-the other rows;  all the rows will then point to the same storage
-location thus saving disk space.
-
-When reading from a variable length array field one can only read as
-many elements as actually exist in that row of the table; reading does
-not automatically continue with the next row of the table as occurs
-when reading an ordinary fixed length table field.  Attempts to read
-more than this will cause an error status to be returned.  One can
-determine the number of elements in each row of a variable column with
-the fits\_read\_descript routine.
-
-**K.  Multiple Access to the Same FITS File
-
-CFITSIO supports simultaneous read and write access to multiple HDUs in
-the same FITS file.  Thus, one can open the same FITS file twice within
-a single program and move to 2 different HDUs in the file, and then
-read and write data or keywords to the 2 extensions just as if one were
-accessing 2 completely separate FITS files.   Since in general it is
-not possible to physically open the same file twice and then expect to
-be able to simultaneously (or in alternating succession) write to 2
-different locations in the file, CFITSIO recognizes when the file to be
-opened (in the call to fits\_open\_file) has already been opened and
-instead of actually opening the file again, just logically links the
-new file to the old file.  (This of course does not prevent the same
-file from being simultaneously opened by more than one program).  Then
-before CFITSIO reads or writes to either (logical) file, it makes sure
-that any modifications made to the other file have been completely
-flushed from the internal buffers to the file.  Thus, in principle, one
-could open a file twice, in one case pointing to the first extension
-and in the other pointing to the 2nd extension and then write data to
-both extensions, in any order, without danger of corrupting the file.
-There may be some efficiency penalties in doing this however, since
-CFITSIO has to flush all the internal buffers related to one file
-before switching to the  other, so it would still be prudent to
-minimize the number of times one switches back and forth between doing
-I/O to different HDUs in the same file.
-
-Some restriction apply:  a FITS file cannot be opened the first time
-with READONLY access, and then opened a second time with READWRITE access,
-because this may be phyically impossible (e.g., if the file resides
-on read-only media such as a CDROM).  Also, in multi-threaded environoments,
-one should never open the same file with write access in different threads.
-
-**L.  When the Final Size of the FITS HDU is Unknown
-
-It is not required to know the total size of a FITS data array or table
-before beginning to write the data to the FITS file.  In the case of
-the primary array or an image extension, one should initially create
-the array with the size of the highest dimension (largest NAXISn
-keyword) set to a dummy value, such as 1.  Then after all the data have
-been written and the true dimensions are known, then the NAXISn value
-should be updated using the fits\_update\_key routine before moving to
-another extension or closing the FITS file.
-
-When writing to FITS tables, CFITSIO automatically keeps track of the
-highest row number that is written to, and will increase the size of
-the table if necessary.  CFITSIO will also automatically insert space
-in the FITS file if necessary, to ensure that the data 'heap', if it
-exists, and/or any additional HDUs that follow the table do not get
-overwritten as new rows are written to the table.
-
-As a general rule it is best to specify the initial number of rows = 0
-when the table is created, then let CFITSIO keep track of the number of
-rows that are actually written.  The application program should not
-manually update the number of rows in the table (as given by the NAXIS2
-keyword) since CFITSIO does this automatically.  If a table is
-initially created with more than zero rows, then this will usually be
-considered as the minimum size of the table, even if fewer rows are
-actually written to the table.  Thus, if a table is initially created
-with NAXIS2 = 20, and CFITSIO only writes 10 rows of data before
-closing the table, then NAXIS2 will remain equal to 20.  If however, 30
-rows of data are written to this table, then NAXIS2 will be increased
-from 20 to 30.  The one exception to this automatic updating of the
-NAXIS2 keyword is if the application program directly modifies the
-value of NAXIS2 (up or down) itself just before closing the table.  In this
-case, CFITSIO does not update NAXIS2 again, since it assumes that the
-application program must have had a good reason for changing the value
-directly.  This is not recommended, however, and is only provided for
-backward compatibility with software that initially creates a table
-with a large number of rows, than decreases the NAXIS2 value to the
-actual smaller value just before closing the table.
-
-**M.  CFITSIO Size Limitations
-
-CFITSIO places very few restrictions on the size of FITS files that it
-reads or writes.  There are a few limits, however, that may affect
-some extreme cases:
-
-1.  The maximum number of FITS files that may be simultaneously opened
-by CFITSIO is set by NMAXFILES as defined in fitsio2.h.  It is currently
-set = 300 by default.  CFITSIO will allocate about 80 * NMAXFILES bytes
-of memory for internal use.  Note that the underlying C compiler or
-operating system, may have a smaller limit on the number of opened files.
-The C symbolic constant FOPEN\_MAX is intended to define the maximum
-number of files that may open at once (including any other text or
-binary files that may be open, not just FITS files).  On some systems it
-has been found that gcc supports a maximum of 255 opened files.
-
-2.  It used to be common for computer systems to only support disk files up
-to 2**31 bytes = 2.1 GB in size, but most systems now support larger files.
-CFITSIO can optionally read and write these so-called 'large files' that 
-are greater than 2.1 GB on
-platforms where they are supported, but this
-usually requires that special compiler option flags be specified to turn
-on this  option.  On linux and solaris systems the compiler flags are
-'-D\_LARGEFILE\_SOURCE' and  `-D\_FILE\_OFFSET\_BITS=64'. These flags
-may also work on other platforms but this has not been tested.  Starting
-with version 3.0 of CFITSIO, the default Makefile that is distributed
-with CFITSIO will include these 2 compiler flags when building on Solaris
-and Linux PC systems.   Users on other platforms will need to add these
-compiler flags manually if they want to support large files.  In most 
-cases it appears that it is not necessary to include these compiler
-flags when compiling application code that call the CFITSIO library 
-routines.
-
-When CFITSIO is built with large file support (e.g., on Solaris and
-Linux PC system by default) then it can read and write FITS data files
-on disk that have any of these conditions:
-
-\begin{itemize}
-\item
-FITS files larger than 2.1 GB in size
-\item
-FITS images containing greater than 2.1 G pixels
-\item
-FITS images that have one dimension with more than 2.1 G pixels
-(as given by one of the NAXISn keyword)
-\item
-FITS tables containing more than 2.1E09 rows (given by the NAXIS2 keyword), 
-or with rows that are more than 2.1 GB wide (given by the NAXIS1 keyword)
-\item
-FITS binary tables with a variable-length array heap that is larger
-than 2.1 GB (given by the PCOUNT keyword)
-\end{itemize}
-
-The current maximum FITS file size supported by  CFITSIO 
-is about 6 terabytes (containing
-2**31 FITS blocks, each 2880 bytes in size). Currently, support for large 
-files in CFITSIO has been tested on the Linux, Solaris, and IBM AIX 
-operating systems.
-
-Note that when writing application programs that are intended to support
-large files it is important to use 64-bit integer variables
-to store quantities such as the dimensions of images, or the number of
-rows in a table.  These programs must also call the special versions 
-of some of the CFITSIO routines that have been adapted to
-support 64-bit integers.  The names of these routines end in
-'ll' ('el' 'el') to distinguish them from the 32-bit integer
-version (e.g.,  fits\_get\_num\_rowsll).
-
-
-*V.  Basic CFITSIO Interface Routines
- 
-This chapter describes the basic routines in the CFITSIO user interface
-that provide all the functions normally needed to read and write most
-FITS files.  It is recommended that these routines be used for most
-applications and that the more advanced routines described in the
-next chapter only be used in special circumstances when necessary.
-
-The following conventions are used in this chapter in the description
-of each function:
-
-1. Most functions have 2 names: a long descriptive name and a short
-concise name.  Both names are listed on the first line of the following
-descriptions, separated by a slash (/) character.  Programmers may use
-either name in their programs but the long names are recommended to
-help document the code and make it easier to read.
-
-2. A right arrow symbol ($>$) is used in the function descriptions to
-separate the input parameters from the output parameters in the
-definition of each routine.  This symbol is not actually part of the C
-calling sequence. 
-
-3. The function parameters are defined in more detail in the
-alphabetical listing in Appendix B.
-
-4.  The first argument in almost all the functions is a pointer to a
-structure of type `fitsfile'.  Memory for this structure is allocated
-by CFITSIO when the FITS file is first opened or created and is freed
-when the FITS file is closed.
-
-5.  The last argument in almost all the functions is the error status
-parameter.  It must be equal to 0 on input, otherwise the function will
-immediately exit without doing anything.  A non-zero output value
-indicates that an error occurred in the function.  In most cases the
-status value is also returned as the value of the function itself.
-
-**A.  CFITSIO Error Status Routines
-
->1  Return a descriptive text string (30 char max.) corresponding to 
->   a CFITSIO error status code.\label{ffgerr}
--
-  void fits_get_errstatus / ffgerr (int status, > char *err_text)
--
->2  Return the top (oldest) 80-character error message from the
-    internal CFITSIO stack of error messages and shift any remaining
-    messages on the stack up one level.  Call this routine
-    repeatedly to get each message in sequence.  The function returns
-   a value = 0 and a null error message when the error stack is empty.
->\label{ffgmsg}
--
-  int fits_read_errmsg / ffgmsg (char *err_msg)
--
->3  Print out the error message corresponding to the input status
-    value and all the error messages on the CFITSIO stack to the specified
-    file stream  (normally to stdout or stderr).  If the input
-    status value = 0 then this routine does nothing.
->\label{ffrprt}
--
-  void fits_report_error / ffrprt (FILE *stream, status)
--
->4 The fits\_write\_errmark routine puts an invisible marker on the 
-   CFITSIO error stack.  The fits\_clear\_errmark routine can then be
-   used to delete any more recent error messages on the stack, back to
-   the position of the marker.  This preserves any older error messages
-   on the stack.  The fits\_clear\_errmsg routine simply clears all the
-   messages (and marks) from the stack.  These routines are called
-   without any arguments.
->\label{ffpmrk}  \label{ffcmsg}
--
-  void fits_write_errmark / ffpmrk (void)
-  void fits_clear_errmark / ffcmrk (void)
-  void fits_clear_errmsg / ffcmsg (void)
--
-
-**B.  FITS File Access Routines
-
->1  Open an existing data file. \label{ffopen}
-
--
-int fits_open_file / ffopen
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_diskfile / ffdkopen
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_data / ffdopn
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_table / fftopn
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_image / ffiopn
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
--
-
-The iomode parameter determines the read/write access allowed in the
-file and can have values of READONLY (0) or READWRITE (1). The filename
-parameter gives the name of the file to be opened, followed by an
-optional argument giving the name or index number of the extension
-within the FITS file that should be moved to and opened (e.g.,
-\verb-myfile.fits+3- or \verb-myfile.fits[3]- moves to the 3rd extension within
-the file, and \verb-myfile.fits[events]- moves to the extension with the
-keyword EXTNAME = 'EVENTS').
-
-The fits\_open\_diskfile routine is similar to the fits\_open\_file routine
-except that it does not support the extended filename syntax in the input
-file name.  This routine simply tries to open the specified input file
-on magnetic disk.  This routine is mainly for use in cases where the
-filename (or directory path) contains square or curly bracket characters
-that would confuse the extended filename parser.
-
-The fits\_open\_data routine is similar to the fits\_open\_file routine
-except that it will move to the first HDU containing significant data,
-if a HDU name or number to open was not explicitly specified as
-part of the filename.  In this case, it will look for the first
-IMAGE HDU with NAXIS greater than 0, or the first table that does not contain the
-strings `GTI' (Good Time Interval extension) or `OBSTABLE' in the
-EXTNAME keyword value.
-
-The fits\_open\_table and fits\_open\_image routines are similar to
-fits\_open\_data except they will move to the first significant table
-HDU or image HDU in the file, respectively, if a HDU name or
-number is not specified as part of the filename.
-
-IRAF images (.imh format files) and raw binary data arrays may also be
-opened with READONLY access.  CFITSIO will automatically test if the
-input file is an IRAF image, and if, so will convert it on the fly into
-a virtual FITS image before it is opened by the application program.
-If the input file is a raw binary data array of numbers, then the data type
-and dimensions of the array must be specified in square brackets
-following the name of the file (e.g.  'rawfile.dat[i512,512]' opens a
-512 x 512 short integer image).  See the `Extended File Name Syntax'
-chapter for more details on how to specify the raw file name.  The raw
-file is converted on the fly into a virtual FITS image in memory that
-is then opened by the application program with READONLY access.
-
-Programs can read the input file from the 'stdin' file stream if a dash
-character ('-') is given as the filename. Files can also be opened over
-the network using FTP or HTTP protocols by supplying the appropriate URL
-as the filename. 
-
-The input file can be modified in various ways to create a virtual file
-(usually stored in memory) that is then opened by the application
-program by supplying a filtering or binning specifier in square brackets
-following the filename. Some of the more common filtering methods are
-illustrated in the following paragraphs, but users should refer to the
-'Extended File Name Syntax' chapter for a complete description of
-the full file filtering syntax. 
-
-When opening an image, a rectangular subset of the physical image may be
-opened by listing the first and last pixel in each dimension (and
-optional pixel skipping factor):
--
-myimage.fits[101:200,301:400]
--
-will create and open a 100x100 pixel virtual image of that section of
-the physical image, and \verb+myimage.fits[*,-*]+ opens a virtual image
-that is the same size as the physical image but has been flipped in
-the vertical direction.
-
-When opening a table, the filtering syntax can be used to add or delete
-columns or keywords in the virtual table: 
-\verb-myfile.fits[events][col !time; PI = PHA*1.2]- opens a virtual table in which the TIME column
-has been deleted and a new PI column has been added with a value 1.2
-times that of the PHA column. Similarly, one can filter a table to keep
-only those rows that satisfy a selection criterion:
-\verb-myfile.fits[events][pha > 50]- creates and opens a virtual table
-containing only those rows with a PHA value greater than 50. A large
-number of boolean and mathematical operators can be used in the
-selection expression. One can also filter table rows using 'Good Time
-Interval' extensions, and spatial region filters as in
-\verb-myfile.fits[events][gtifilter()]- and
-\verb-myfile.fits[events][regfilter( "stars.rng")]-.
-
-Finally, table columns may be binned or histogrammed to generate a
-virtual image. For example, \verb-myfile.fits[events][bin (X,Y)=4]- will
-result in a 2-dimensional image calculated by binning the X and Y
-columns in the event table with a bin size of 4 in each dimension. The
-TLMINn and TLMAXn keywords will be used by default to determine the
-range of the image. 
-
-A single program can open the same FITS file more than once and then
-treat the resulting fitsfile pointers as though they were completely
-independent FITS files. Using this facility, a program can open a FITS
-file twice, move to 2 different extensions within the file, and then
-> read and write data in those extensions in any order.
-
->2   Create and open a new empty output FITS file. \label{ffinit}

--
-
-An error will be returned if the specified file already exists, unless
-the filename is prefixed with an exclamation point (!). In that case
-CFITSIO will overwrite (delete) any existing file with the same name.
-Note that the exclamation point is a special UNIX character so if
-it is used on the command line it must be preceded by a backslash to
-force the UNIX shell to accept the character as part of the filename. 
-
-The output file will be written to the 'stdout' file stream if a dash
-character ('-') or the string 'stdout' is given as the filename. Similarly,
-'-.gz' or 'stdout.gz' will cause the file to be gzip compressed before
-it is written out to the stdout stream.
-
-Optionally, the name of a template file that is used to define the
-structure of the new file may be specified in parentheses following the
-output file name. The template file may be another FITS file, in which
-case the new file, at the time it is opened, will be an exact copy of
-the template file except that the data structures (images and tables)
-will be filled with zeros. Alternatively, the template file may be an
-ASCII format text file containing directives that define the keywords to be
-created in each HDU of the file. See the 'Extended File Name Syntax'
- section for a complete description of the template file syntax. 
- 
-The fits\_create\_diskfile routine is similar to the fits\_create\_file routine
-except that it does not support the extended filename syntax in the input
-file name.  This routine simply tries to create the specified file
-on magnetic disk.  This routine is mainly for use in cases where the
-filename (or directory path) contains square or curly bracket characters
-> that would confuse the extended filename parser.
-
-
->3  Close a previously opened FITS file.  The first routine simply
-closes the file, whereas the second one also DELETES THE FILE, which
-can be useful in cases where a FITS file has been partially created,
-but then an error occurs which prevents it from being completed.

-**C.  HDU Access Routines
-
-The following functions perform operations on Header-Data Units (HDUs)
-as a whole.
-
->1  Move to a different HDU in the file.  The first routine moves to a
-    specified absolute HDU number (starting with 1 for the primary
-    array) in the FITS file, and the second routine moves a relative
-    number HDUs forward or backward from the current HDU.  A null
-    pointer may be given for the hdutype parameter if it's value is not
-    needed.  The third routine moves to the (first) HDU which has the
-    specified extension type and EXTNAME and EXTVER keyword values (or
-    HDUNAME and HDUVER keywords).  The hdutype parameter may have a
-    value of IMAGE\_HDU, ASCII\_TBL, BINARY\_TBL, or ANY\_HDU where
-    ANY\_HDU means that only the extname and extver values will be used
-    to locate the correct extension.  If the input value of extver is 0
-    then the EXTVER keyword is ignored and the first HDU with a
-    matching EXTNAME (or HDUNAME) keyword will be found.  If no
-    matching HDU is found in the file then the current HDU will remain
-    unchanged and a status = BAD\_HDU\_NUM will be returned.

--
->2  Return the total number of HDUs in the FITS file.  This returns the
-number of completely defined HDUs in the file.  If a new HDU has just been added to 
-the FITS file, then that last HDU will only be counted if it has been closed,
-or if data has been written to the HDU.
->   The current HDU remains unchanged by this routine. \label{ffthdu}
--
-  int fits_get_num_hdus / ffthdu
-      (fitsfile *fptr, > int *hdunum, int *status)
--
->3  Return the number of the current HDU (CHDU) in the FITS file (where
-    the primary array = 1).  This function returns the HDU number
->   rather than a status value.  \label{ffghdn}
--
-  int fits_get_hdu_num / ffghdn
-      (fitsfile *fptr, > int *hdunum)

->4  Return the type of the current HDU in the FITS file.  The possible

--
-  int fits_get_hdu_type / ffghdt
-      (fitsfile *fptr, > int *hdutype, int *status)
--
->5  Copy all or part of the HDUs in the FITS file associated with infptr
-    and append them to the end of the FITS file associated with
-    outfptr.  If 'previous' is true (not 0), then any HDUs preceding
-    the current HDU in the input file will be copied to the output
-    file.  Similarly, 'current' and 'following' determine whether the
-    current HDU, and/or any following HDUs in the input file will be
-    copied to the output file. Thus, if all 3 parameters are true, then the
-    entire input file will be copied.  On exit, the current HDU in
-    the input file will be unchanged, and the last HDU in the output
->   file will be the current HDU.  \label{ffcpfl}

-  int fits_write_hdu / ffwrhdu
-      (fitsfile *infptr, FILE *stream, > int *status)
--
->8   Copy the header (and not the data) from the CHDU associated with infptr
-    to the CHDU associated with outfptr.  If the current output HDU
-    is not completely empty, then the CHDU will be closed and a new
-    HDU will be appended to the output file.   An empty output data unit
->   will be created with all values initially = 0). \label{ffcphd}
--
-  int fits_copy_header / ffcphd
-      (fitsfile *infptr, fitsfile *outfptr, > int *status)
--
->9   Delete the CHDU in the FITS file.  Any following HDUs will be shifted
-    forward in the file, to fill in the gap created by the deleted
-    HDU.  In the case of deleting the primary array (the first HDU in
-    the file) then the current primary array will be replace by a null
-    primary array containing the minimum set of required keywords and
-    no data.  If there are more extensions in the file following the
-    one that is deleted, then the the CHDU will be redefined to point
-    to the following extension.  If there are no following extensions
-    then the CHDU will be redefined to point to the previous HDU.  The
-    output hdutype parameter returns the type of the new CHDU.  A null
-    pointer may be given for

-**D.  Header Keyword Read/Write Routines
-
-These routines read or write keywords in the Current Header Unit
-(CHU).  Wild card characters (*, ?, or \#) may be used when specifying
-the name of the keyword to be read: a '?' will match any single
-character at that position in the keyword name and a '*' will match any
-length (including zero) string of characters.  The '\#' character will
-match any consecutive string of decimal digits (0 - 9).  When a wild
-card is used the routine will only search for a match from the current
-header position to the end of the header and will not resume the search
-from the top of the header back to the original header position as is
-done when no wildcards are included in the keyword name.  The
-fits\_read\_record routine may be used to set the starting position
-when doing wild card searches.  A status value of KEY\_NO\_EXIST is
-returned if the specified keyword to be read is not found in the
-header.
-
-***1.  Keyword Reading Routines
-
->1  Return the number of existing keywords (not counting the
-    END keyword) and the amount of space currently available for more
-    keywords.  It returns morekeys = -1 if the header has not yet been
-    closed.  Note that CFITSIO will dynamically add space if required
-    when writing new keywords to a header so in practice there is no
-    limit to the number of keywords that can be added to a header.  A
-    null pointer may be entered for the morekeys parameter if it's
->   value is not needed. \label{ffghsp}
--
-  int fits_get_hdrspace / ffghsp
-      (fitsfile *fptr, > int *keysexist, int *morekeys, int *status)
--
->2  Return the specified keyword.  In the first routine, 
-    the datatype parameter specifies the desired returned data type of the
-    keyword value and can have one of the following symbolic constant
-    values:  TSTRING, TLOGICAL (== int), TBYTE, TSHORT, TUSHORT, TINT,
-    TUINT, TLONG, TULONG, TLONGLONG, TFLOAT, TDOUBLE, TCOMPLEX, and TDBLCOMPLEX.
-    Within the context of this routine, TSTRING corresponds to a
-    'char*' data type, i.e., a pointer to a character array.  Data type
-    conversion will be performed for numeric values if the keyword
-    value does not have the same data type.  If the value of the keyword
-    is undefined (i.e., the value field is blank) then an error status
-    = VALUE\_UNDEFINED will be returned.
-
-    The second routine returns the keyword value as a character string
-    (a literal copy of what is in the value field) regardless of the
-    intrinsic data type of the keyword.  The third routine returns
-    the entire 80-character header record of the keyword, with any
-    trailing blank characters stripped off. The fourth routine returns
-    the (next) header record that contains the literal string of characters
-    specified by the 'string' argument.
-
-    If a NULL comment pointer is supplied then the comment string
->   will not be returned. \label{ffgky} \label{ffgkey} \label{ffgcrd}

-
-  int fits_read_str / ffgstr
-      (fitsfile *fptr, char *string, > char *card, int *status)
--
->3  Return the nth header record in the CHU.  The first keyword
-   in the header is at keynum = 1;  if keynum = 0 then these routines
-   simply reset the internal CFITSIO pointer to the beginning of the header
-   so that subsequent keyword operations will start at the top of the
-   header (e.g., prior to searching for keywords using wild cards in
-   the keyword name).   The first routine returns the entire
-   80-character header record (with trailing blanks truncated), 
-   while the second routine parses the record and returns the name,
-   value, and comment fields as separate (blank truncated)
-   character strings.  If a NULL comment pointer is given on input,
-   then the comment string will not be 
->  returned. \label{ffgrec} \label{ffgkyn}
--
-  int fits_read_record / ffgrec
-      (fitsfile *fptr, int keynum, > char *card, int *status)

-  int fits_read_keyn / ffgkyn
-      (fitsfile *fptr, int keynum, > char *keyname, char *value,
-       char *comment, int *status)
--
->4  Return the next keyword whose name matches one of the strings in
-    'inclist' but does not match any of the strings in 'exclist'.
-    The strings in inclist and exclist may contain wild card characters
-    (*, ?, and \#) as described at the beginning of this section.
-    This routine searches from the current header position to the
-    end of the header, only, and does not continue the search from
-    the top of the header back to the original position.  The current
-    header position may be reset with the ffgrec routine.  Note
-    that nexc may be set = 0 if there are no keywords to be excluded.
-    This routine returns status = KEY\_NO\_EXIST if a matching
->   keyword is not found. \label{ffgnxk}

-      (fitsfile *fptr, char **inclist, int ninc, char **exclist,
-       int nexc, > char *card, int  *status)
--
->5  Return the physical units string from an existing keyword.  This
-    routine uses a local convention, shown in the following example,
-    in which the keyword units are enclosed in square brackets in the
-    beginning of the keyword comment field.  A null string is returned
->   if no units are defined for the keyword.  \label{ffgunt}
--

-
-  int fits_read_key_unit / ffgunt
-      (fitsfile *fptr, char *keyname, > char *unit, int *status)
--
->6  Concatenate the header keywords in the CHDU into a single long
-    string of characters.  This provides a convenient way of passing
-    all or part of the header information in a FITS HDU to other subroutines.
-    Each 80-character fixed-length keyword record is appended to the
-    output character string, in order, with no intervening separator or
-    terminating characters. The last header record is terminated with
-    a NULL character.  These routine allocates memory for the returned
-    character array, so the calling program must free the memory when
-    finished.  The cleanest way to do this is to 
-    call the fits\_free\_memory routine.
-
-    There are 2 related routines: fits\_hdr2str simply concatenates all
-    the existing keywords in the header; fits\_convert\_hdr2str is similar,
-    except that if the CHDU is a tile compressed image (stored in a binary
-    table) then it will first convert that header back to that of the corresponding
-    normal FITS image before concatenating the keywords.
-
-    Selected keywords may be excluded from the returned character string.
-    If the second parameter (nocomments) is TRUE (nonzero) then any
-    COMMENT, HISTORY, or blank keywords in the header will not be copied
-    to the output string.
-
-    The 'exclist' parameter may be used to supply a list of keywords
-    that are to be excluded from the output character string. Wild card
-    characters (*, ?, and \#) may be used in the excluded keyword names.
-    If no additional keywords are to be excluded, then set nexc = 0 and
->   specify NULL for the the **exclist  parameter.  \label{ffhdr2str}

-
-***2.  Keyword Writing Routines
-
->1  Write a keyword of the appropriate data type into the
-    CHU.  The first routine simply appends a new keyword whereas the
-    second routine will update the value and comment fields of the
-    keyword if it already exists, otherwise it appends a new
-    keyword.  Note that the address to the value, and not the value
-    itself, must be entered.    The datatype parameter specifies the
-    data type of the keyword value with one of the following values:
-    TSTRING, TLOGICAL (== int), TBYTE, TSHORT, TUSHORT, TINT, TUINT,
-    TLONG, TLONGLONG, TULONG, TFLOAT, TDOUBLE.  Within the context of this
-    routine, TSTRING corresponds to a 'char*' data type, i.e., a pointer
-    to a character array.  A null pointer may be entered for the
-    comment parameter in which case the  keyword comment
->   field will be unmodified or left blank.  \label{ffpky} \label{ffuky}

--
->2  Write a keyword with a null or undefined value (i.e., the
-    value field in the keyword is left blank).  The first routine
-    simply appends a new keyword whereas the second routine will update
-    the value and comment fields of the keyword if it already exists,
-    otherwise it appends a new keyword.  A null pointer may be
-    entered for the comment parameter in which case the  keyword

--
->4  Write the DATE keyword to the CHU. The keyword value will contain
-    the current system date as a character string in 'yyyy-mm-ddThh:mm:ss' 
-    format. If a DATE keyword already exists in the header, then this
-    routine will simply update the keyword value with the current date.

--
-  int fits_write_record / ffprec
-      (fitsfile *fptr, char *card, > int *status)

->6 Update an 80-character record in the CHU.  If a keyword with the input
-   name already exists, then it is overwritten by the value of card.  This
-   could modify the keyword name as well as the value and comment fields.
-   If the keyword doesn't already exist then a new keyword card is appended

-    whereas the second routine deletes a specifically named keyword.

-**E.  Primary Array or IMAGE Extension I/O Routines 
- 
-These routines read or write data values in the primary data array (i.e.,
-the first HDU in a FITS file) or an IMAGE extension.   There are also
-routines to get information about the data type and size of the image.
-Users should also read the following chapter on the CFITSIO iterator
-function which provides a more `object oriented' method of reading and
-writing images.  The iterator function is a little more complicated to
-use, but the advantages are that it usually takes less code to perform
-the same operation, and the resulting program often runs faster because
-the FITS files are read and written using the most efficient block size.
-
-C programmers should note that the ordering of arrays in FITS files, and
-hence in all the CFITSIO calls, is more similar to the dimensionality
-of arrays in Fortran rather than C.  For instance if a FITS image has
-NAXIS1 = 100 and NAXIS2 = 50, then a 2-D array just large enough to hold
-the image should be declared as array[50][100] and not as array[100][50].
-
-The `datatype'  parameter specifies the data type of the `nulval'  and
-`array' pointers and can have one of the following  values:  TBYTE,
-TSBYTE, TSHORT, TUSHORT, TINT, TUINT, TLONG, TLONGLONG, TULONG, TFLOAT,
-TDOUBLE.  Automatic data type conversion is performed if the data type
-of the FITS array (as defined by the BITPIX keyword) differs from that
-specified by 'datatype'.  The data values are also automatically scaled
-by the BSCALE and BZERO keyword values as they are being read or written
-in the FITS array.
-
->1  Get the data type or equivalent data type of the image.  The 
-    first routine returns the physical data type of the FITS image, as
-    given by the BITPIX keyword, with allowed values of BYTE\_IMG (8),
-    SHORT\_IMG (16), LONG\_IMG (32), LONGLONG\_IMG (64), 
-    FLOAT\_IMG (-32), and DOUBLE\_IMG
-    (-64).  
-    The second routine is similar, except that if the image pixel
-    values are scaled, with non-default values for the BZERO and BSCALE
-    keywords, then the routine will return the 'equivalent' data type
-    that is needed to store the scaled values.  For example, if BITPIX
-    = 16 and BSCALE = 0.1 then the equivalent data type is FLOAT\_IMG.
-    Similarly if BITPIX = 16, BSCALE = 1, and BZERO = 32768, then the
-    the pixel values span the range of an unsigned short integer and
->   the returned data type will be USHORT\_IMG. \label{ffgidt}

->4  Copy an n-dimensional image in a particular row and column of a 
-    binary table (in a vector column) 
-    to or from a primary array or image extension.
-    
-    The 'cell2image' routine
-    will append a new image extension (or primary array) to the output file.
-    Any WCS keywords associated with the input column image will be translated
-    into the appropriate form for an image extension.  Any other keywords
-    in the table header that are not specifically related to defining the 
-    binary table structure or to other columns in the table 
-    will also be copied to the header of the output image.
-
-    The 'image2cell' routine will copy the input image into the specified row
-    and column of the current binary table in the output file.  The binary table
-    HDU must exist before calling this routine, but it
-    may be empty, with no rows or columns of data.  The specified column
-    (and row) will be created if it does not already exist.  The 'copykeyflag'
-    parameter controls which keywords are copied from the input
-    image to the header of the output table: 0 = no keywords will be copied,
-    1 = all keywords will be copied (except those keywords that would be invalid in 
->   the table header), and 2 = copy only the WCS keywords. \label{copycell}

->5  Write a rectangular subimage (or the whole image) to the FITS data

-      (fitsfile *fptr, int datatype, long *fpixel, long *lpixel,

->6  Write pixels into the FITS data array.  'fpixel' is an array of
-   length NAXIS which gives the coordinate of the starting pixel to be
-   written to, such that fpixel[0] is in the range 1 to NAXIS1,
-   fpixel[1] is in the range 1 to NAXIS2, etc.  The first pair of routines
-   simply writes the array of pixels to the FITS file (doing data type
-   conversion if necessary) whereas the second routines will substitute
-   the  appropriate FITS null value for any elements which are equal to
-   the input value of nulval (note that this parameter gives the
-   address of the null value, not the null value itself).  For integer
-   FITS arrays, the FITS null value is defined by the BLANK keyword (an
-   error is returned if the BLANK keyword doesn't exist).  For floating
-   point FITS arrays  the special IEEE NaN (Not-a-Number) value will be
-   written into the FITS file.  If a null pointer is entered for
-   nulval, then the null value is ignored and this routine behaves

->8  Read a rectangular subimage (or the whole image) from the FITS 
-    data array.  The fpixel and lpixel arrays give the coordinates of
-    the first (lower left corner) and last (upper right corner) pixels
-    to be read from the FITS image. Undefined FITS array elements will
-    be returned with a value = *nullval, (note that this parameter

--
->9  Read pixels from the FITS data array.  'fpixel' is the starting
-    pixel location and is an array of length NAXIS such that fpixel[0]
-    is in the range 1 to NAXIS1, fpixel[1] is in the range 1 to NAXIS2,
-    etc. The nelements parameter specifies the number of pixels to
-    read.  If fpixel is set to the first pixel, and nelements is set
-    equal to the NAXIS1 value, then this routine would read the first
-    row of the image.  Alternatively, if nelements is set equal to
-    NAXIS1 * NAXIS2 then it would read an entire 2D image, or the first
-    plane of a 3-D datacube.
-
-    The first 2 routines will return any undefined pixels in the FITS array
-    equal to the value of *nullval (note that this parameter gives the

-**F.  Image Compression  
-
-CFITSIO transparently supports the 2 methods of image compression described 
-below.
-
-1)  The entire FITS file may be externally compressed with the gzip or Unix
-compress utility programs, producing a *.gz or *.Z file, respectively. When reading
-compressed files of this type, CFITSIO first uncompresses the entire file
-into memory before performing the requested read operations.  Output files
-can be directly written in the gzip compressed format if the user-specified
-filename ends with `.gz'.  In this case, CFITSIO initially writes the
-uncompressed file in memory and then compresses it and writes it to disk
-when the FITS file is closed, thus saving user disk space. Read and write
-access to these compressed FITS files is generally quite fast since all the
-I/O is performed in memory; the main limitation with this technique is that
-there must be enough available memory (or swap space) to hold the entire
-uncompressed FITS file.
-
-2) CFITSIO also supports the FITS tiled image compression convention in
-which the image is subdivided into a grid of rectangular tiles, and each
-tile of pixels is individually compressed.   The details of this FITS
-compression  convention are described at the FITS Support Office web site at
-http://fits.gsfc.nasa.gov/fits\_registry.html  Basically, the compressed
-image tiles are stored in rows of a variable length array column in a FITS
-binary table, however CFITSIO recognizes that this binary table extension
-contains an image and treats it as if it were an IMAGE extension.  This
-tile-compressed format is especially well suited for compressing very large
-images because a) the FITS header keywords remain uncompressed for rapid
-read access, and because b) it is possible to extract and uncompress
-sections of the image without having to uncompress the entire image. This
-format is also much more effective in compressing floating point images 
-than simply compressing the image using gzip or compress because it
-approximates the floating point values with scaled integers which can then
-be compressed more efficiently.
-
-Currently CFITSIO supports 3 general purpose compression algorithms  plus
-one other special-purpose compression technique that is designed for data
-masks with positive integer pixel values. The 3 general purpose algorithms
-are GZIP, Rice, and HCOMPRESS, and the special purpose  algorithm is the
-IRAF pixel list compression technique (PLIO). In principle, any number of
-other compression algorithms could also be supported  by the FITS tiled
-image compression convention.
-
-The FITS image can be subdivided into any desired rectangular grid of
-compression tiles.  With the GZIP, Rice,  and PLIO algorithms, the default
-is to take each row of the image as a tile.  The HCOMPRESS algorithm is
-inherently 2-dimensional in nature, so the default in this case is to take
-16 rows of the image per tile. In most cases it makes little difference what
-tiling pattern is used, so the default tiles are usually adequate.  In the
-case of very small images, it could be more efficient to compress the whole
-image as a single tile. Note that the image dimensions are not required to
-be an integer multiple of the tile dimensions; if not, then the tiles at the
-edges of the image will be smaller than the other tiles.
-
-The 4 supported image compression algorithms are all 'loss-less' when
-applied to integer FITS images;  the pixel values are preserved exactly with
-no loss of information during the compression and uncompression process.  In
-addition, the HCOMPRESS algorithm supports a 'lossy' compression mode that
-will produce
-larger amount of image compression.  This is achieved by specifying a non-zero
-value for the HCOMPRESS ``scale'' 
-parameter.  Since the amount of compression that is achieved depends directly
-on the RMS noise in the image, it is usually more convention
-to specify the HCOMPRESS scale factor relative to the RMS noise.  
-Setting s = 2.5 means use a scale factor that is 2.5 times the calculated RMS noise
-in the image tile.   In some cases
-it may be desirable to specify the exact scaling to be used,
-instead of specifying it relative to the calculated noise value.  This may
-be done by specifying the negative of desired scale value (typically
-in the range -2 to -100).
-
-Very high compression factors (of 100 or more) can be
-achieved by using large HCOMPRESS scale values, however, this can produce undesirable
-``blocky'' artifacts in the compressed image.  A variation of the HCOMPRESS
-algorithm (called HSCOMPRESS) can be used in this case to apply a small
-amount of smoothing of the image when it is uncompressed to help cover up
-these artifacts.  This smoothing is purely cosmetic and does not cause any
-significant change to the image pixel values. 
-
-Floating point FITS images (which have BITPIX = -32 or -64) usually contain
-too much ``noise'' in the least significant bits of the mantissa of the
-pixel values  to be effectively compressed with any lossless algorithm.
-Consequently, floating point images are first quantized into scaled integer
-pixel values (and thus throwing away much of the noise) before being
-compressed with the specified algorithm (either GZIP, Rice, or HCOMPRESS).  
-This technique produces much higher compression factors than
-simply using the GZIP utility to externally compress the whole FITS file,  but it also
-means that the original floating value pixel values are not exactly
-preserved. When done properly, this  integer scaling technique will only
-discard the insignificant noise while still preserving all the real
-information in the image.  The amount of precision that is retained in the
-pixel values is controlled by the "quantization level" parameter, q.  Larger
-values of q will result in compressed images whose pixels more closely match
-the floating point pixel values, but at the same time the amount of
-compression that is achieved will be reduced.  Users should experiment with
-different values for  this parameter to determine the optimal value that
-preserves all the useful information in the image, without needlessly
-preserving all the ``noise'' which will hurt the compression efficiency.
-
-The default value for the quantization scale factor is 16., which means that
-scaled integer pixel values will be quantized such that the difference
-between adjacent integer values will be 1/16th of the noise level in the
-image background. CFITSIO uses an optimized algorithm to accurately estimate
-the noise in the image.  As an example, if the RMS noise in the background
-pixels of an  image = 32.0,  then the spacing between adjacent scaled
-integer pixel values  will equal 2.0 by default.  Note that the RMS noise is
-independently calculated for each tile of the image, so the resulting
-integer scaling factor may fluctuate slightly for each tile.   In some cases
-it may be desirable to specify the exact quantization level to be used,
-instead of specifying it relative to the calculated noise value.  This may
-be done by specifying the negative of desired quantization level for the
-value of q.  In the previous example, one could specify q = -2.0 so that the
-quantized integer levels differ by 2.0.  Larger negative values for q means
-that the levels are more coarsely spaced, and will produce higher
-compression factors.
-
-There are 2 methods for specifying all the parameters needed to write a FITS
-image in the tile compressed format.  The parameters may either be specified
-at run time as part of the file name of the output compressed FITS file, or
-the writing program may call a set of helper CFITSIO subroutines that are provided
-for specifying the parameter values, as described below:
-
-1)  At run time, when specifying the name of the output FITS file to be
-created, the user can indicate that images should be
-written in tile-compressed format by enclosing the compression
-parameters in square brackets following the root disk file name
-in the following format:
--
-    [compress NAME T1,T2; q QLEVEL, s HSCALE]
--
-where
--
-    NAME   = algorithm name:  GZIP, Rice, HCOMPRESS, HSCOMPRSS or PLIO
-             may be abbreviated to the first letter (or HS for HSCOMPRESS)
-    T1,T2  = tile dimension (e.g. 100,100 for square tiles 100 pixels wide)
-    QLEVEL = quantization level for floating point FITS images
-    HSCALE = HCOMPRESS scale factor; default = 0 which is lossless.
-- 
-
-Here are a few examples of this extended syntax:
-
--
-    myfile.fit[compress]    - use the default compression algorithm (Rice)
-                              and the default tile size (row by row)
-
-    myfile.fit[compress GZIP] - use the specified compression algorithm;
-    myfile.fit[compress Rice]     only the first letter of the algorithm 
-    myfile.fit[compress PLIO]     name is required.
-    myfile.fit[compress HCOMP]
-    
-    myfile.fit[compress R 100,100]   - use Rice and 100 x 100 pixel tiles 
-
-    myfile.fit[compress R; q 10.0] - quantization level = (RMS-noise) / 10.
-    myfile.fit[compress HS; s 2.0]  -  HSCOMPRESS (with smoothing)
-                                          and scale = 2.0 * RMS-noise
--
-
-2)  Before calling the CFITSIO routine to write the image header
-keywords (e.g., fits\_create\_image) the programmer can call the
-routines described below to specify the compression algorithm and the
-tiling pattern that is to be used.  There are routines for specifying
-the various compression parameters and similar routines to
-return the current values of the parameters:
-\label{ffsetcomp}  \label{ffgetcomp}
--
-  int fits_set_compression_type(fitsfile *fptr, int comptype, int *status)
-  int fits_set_tile_dim(fitsfile *fptr, int ndim, long *tilesize, int *status)
-  int fits_set_quantize_level(fitsfile *fptr, float qlevel, int *status)
-  int fits_set_hcomp_scale(fitsfile *fptr, float scale, int *status)
-  int fits_set_hcomp_smooth(fitsfile *fptr, int smooth, int *status)
-              Set smooth = 1 to apply smoothing when uncompressing the image
-
-  int fits_get_compression_type(fitsfile *fptr, int *comptype, int *status)
-  int fits_get_tile_dim(fitsfile *fptr, int ndim, long *tilesize, int *status)
-  int fits_get_quantize_level(fitsfile *fptr, float *level, int *status)
-  int fits_get_hcomp_scale(fitsfile *fptr, float *scale, int *status)
-  int fits_get_hcomp_smooth(fitsfile *fptr, int *smooth, int *status)
--
-4 symbolic constants are defined for use as the value of the
-`comptype' parameter:  GZIP\_1, RICE\_1, HCOMPRESS\_1 or PLIO\_1.  
-Entering NULL for
-comptype will turn off the tile-compression and cause normal FITS
-images to be written.
-
-
-No special action is required by software when read tile-compressed images because
-all the CFITSIO routines that read normal uncompressed FITS images also
-transparently read images in the tile-compressed format;  CFITSIO essentially
-treats the binary table that contains the compressed tiles as if
-it were an IMAGE extension.
-
-
-The following 2 routines are available for compressing or
-or decompressing an image:
--
-  int fits_img_compress(fitsfile *infptr, fitsfile *outfptr, int *status);
-  int fits_img_decompress (fitsfile *infptr, fitsfile *outfptr, int *status);
--
-Before calling the compression routine, the compression parameters must
-first be defined in one of the 2 way described in the previous paragraphs.
-There is also a routine to determine if the current HDU contains
-a tile compressed image (it returns 1 or 0):
--
-  int fits_is_compressed_image(fitsfile *fptr, int *status);
--
-A small example program called 'imcopy' is included with CFITSIO that
-can be used to compress (or uncompress) any FITS image.  This
-program can be used to experiment with the various compression options
-on existing FITS images as shown in these examples:
--
-1)  imcopy infile.fit 'outfile.fit[compress]' 
-
-       This will use the default compression algorithm (Rice) and the
-       default tile size (row by row)
-
-2)  imcopy infile.fit 'outfile.fit[compress GZIP]' 
-
-       This will use the GZIP compression algorithm and the default
-       tile size (row by row).  The allowed compression algorithms are
-       Rice, GZIP, and PLIO.  Only the first letter of the algorithm
-       name needs to be specified.
-
-3)  imcopy infile.fit 'outfile.fit[compress G 100,100]' 
-
-       This will use the GZIP compression algorithm and 100 X 100 pixel
-       tiles.
-
-4)  imcopy infile.fit 'outfile.fit[compress R 100,100; q 10.0]' 
-
-       This will use the Rice compression algorithm, 100 X 100 pixel
-       tiles, and quantization level = RMSnoise / 10.0 (assuming the 
-       input image has a floating point data type).  
-
-5)  imcopy infile.fit outfile.fit
-
-       If the input file is in tile-compressed format, then it will be
-       uncompressed to the output file.  Otherwise, it simply copies
-       the input image to the output image.
-
-6)  imcopy 'infile.fit[1001:1500,2001:2500]'  outfile.fit
-
-       This extracts a 500 X 500 pixel section of the much larger
-       input image (which may be in tile-compressed format).  The
-       output is a normal uncompressed FITS image.
-
-7)  imcopy 'infile.fit[1001:1500,2001:2500]'  outfile.fit.gz
-
-       Same as above, except the output file is externally compressed
-       using the gzip algorithm.

-**G.  ASCII and Binary Table Routines
- 
-These routines perform read and write operations on columns of data in
-FITS ASCII or Binary tables.  Note that in the following discussions,
-the first row and column in a table is at position 1 not 0.
-
-Users should also read the following chapter on the CFITSIO iterator
-function which provides a more `object oriented' method of reading and
-writing table columns.  The iterator function is a little more
-complicated to use, but the advantages are that it usually takes less
-code to perform the same operation, and the resulting program often
-runs faster because the FITS files are read and written using the most
-efficient block size.
-
-***1.  Create New Table
-
->1 Create a new ASCII or bintable table extension. If
-   the FITS file is currently empty then a dummy primary array will be
-   created before appending the table extension to it.  The tbltype
-   parameter defines the type of table and can have values of
-   ASCII\_TBL or BINARY\_TBL.  The naxis2 parameter gives the initial
-   number of rows to be created in the table, and should normally be
-   set = 0.  CFITSIO will automatically increase the size of the table
-   as additional rows are written.  A non-zero number of rows may be
-   specified to reserve space for that many rows, even if a fewer
-   number of rows will be written.  The tunit and extname parameters
-   are optional and a null pointer may be given if they are not
-   defined.  The FITS Standard recommends that only letters, digits,
-   and the underscore character be used in column names (the ttype
-   parameter) with no embedded spaces.  Trailing blank characters are
->   not significant.   \label{ffcrtb}
--
-  int fits_create_tbl / ffcrtb
-      (fitsfile *fptr, int tbltype, LONGLONG naxis2, int tfields, char *ttype[],
-       char *tform[], char *tunit[], char *extname, int *status)
--
-***2.  Column Information Routines
-
->1   Get the number of rows or columns in the current FITS table.
-     The number of rows is given by the NAXIS2 keyword and the
-     number of columns is given by the TFIELDS keyword in the header
->    of the table. \label{ffgnrw} 
--
-  int fits_get_num_rows / ffgnrw 
-      (fitsfile *fptr, > long *nrows, int *status);
-
-  int fits_get_num_rowsll / ffgnrwll
-      (fitsfile *fptr, > LONGLONG *nrows, int *status);
-
-  int fits_get_num_cols / ffgncl
-      (fitsfile *fptr, > int *ncols, int *status);
--
-
->2  Get the table column number (and name) of the column whose name
-matches an input template name.   If casesen  = CASESEN then the column
-name match will be case-sensitive, whereas if casesen = CASEINSEN then
-the case will be ignored.  As a general rule, the column names should
-be treated as case INsensitive.
-
-The input column name template may be either the exact name of the
-column to be searched for, or it may contain wild card characters (*,
-?, or \#), or it may contain the integer number of the desired column
-(with the first column = 1).  The `*' wild card character matches any
-sequence of characters (including zero characters) and the `?'
-character matches any single character.  The \# wildcard will match any
-consecutive string of decimal digits (0-9).  If more than one column
-name in the table matches the template string, then the first match is
-returned and the status value will be set to COL\_NOT\_UNIQUE  as a
-warning that a unique match was not found.  To find the other cases
-that match the template, call the routine again leaving the input
-status value equal to COL\_NOT\_UNIQUE and the next matching name will
-then be returned.  Repeat this process until a status =
-COL\_NOT\_FOUND  is returned.
-
-The FITS Standard recommends that only letters, digits, and the
-underscore character be used in column names (with no embedded
-spaces).  Trailing blank characters are not significant.

-      (fitsfile *fptr, int casesen, char *templt, > char *colname,
-       int *colnum, int *status)
--
->3  Return the data type, vector repeat value, and the width in bytes
-    of a column in an ASCII or binary table.  Allowed values for the
-    data type in ASCII tables are:  TSTRING, TSHORT, TLONG, TFLOAT, and
-    TDOUBLE.  Binary tables also support these types: TLOGICAL, TBIT,
-    TBYTE, TCOMPLEX and TDBLCOMPLEX.  The negative of the data type code
-    value is returned if it is a variable length array column.  Note
-    that in the case of a 'J' 32-bit integer binary table column, this
-    routine will return data type = TINT32BIT (which in fact is
-    equivalent to TLONG).  With most current C compilers, a value in a
-    'J' column has the same size as an 'int' variable, and may not be
-    equivalent to a 'long' variable, which is 64-bits long on an
-    increasing number of compilers.
-
-    The 'repeat' parameter returns the vector repeat count on the binary
-    table TFORMn keyword value. (ASCII table columns always have repeat
-    = 1).  The 'width' parameter returns the width in bytes of a single
-    column element (e.g., a '10D' binary table column will have width =
-    8, an ASCII table 'F12.2' column will have width = 12, and a binary
-    table'60A' character string  column will have width = 60);  Note that
-    CFITSIO supports the local convention for specifying arrays of
-    fixed length strings within a binary table character column using
-    the syntax TFORM = 'rAw' where 'r' is the total number of characters
-    (= the width of the column) and 'w' is the width of a unit string
-    within the column.  Thus if the column has TFORM = '60A12' then this
-    means that each row of the table contains 5 12-character substrings
-    within the 60-character field, and thus in this case this routine will
-    return typecode = TSTRING, repeat = 60, and width = 12.  (The TDIMn
-    keyword may also be used to specify the unit string length; The pair
-    of keywords TFORMn = '60A' and TDIMn = '(12,5)'  would have the
-    same effect as TFORMn = '60A12').  The number
-    of substrings in any binary table character string field can be
-    calculated by (repeat/width).  A null pointer may be given for any of
-    the output parameters that are not needed.
-
-   The second routine, fit\_get\_eqcoltype is similar except that in
-   the case of scaled integer columns it returns the 'equivalent' data
-   type that is needed to store the scaled values, and not necessarily
-   the physical data type of the unscaled values as stored in the FITS
-   table.  For example if a '1I' column in a binary table has TSCALn =
-   1 and TZEROn = 32768, then this column effectively contains unsigned
-   short integer values, and thus the returned value of typecode will
-   be TUSHORT, not TSHORT.  Similarly, if a column has TTYPEn = '1I'
-   and TSCALn = 0.12, then the returned typecode
->  will be TFLOAT. \label{ffgtcl}

->4  Return the display width of a column.  This is the length
-    of the string that will be returned by the fits\_read\_col routine

->   and naxes[0] equal to the repeat count in the TFORM keyword. \label{ffgtdm}

-***3.  Routines to Edit Rows or Columns
-
->1  Insert or delete rows in an ASCII or binary table. When inserting rows
-    all the rows following row FROW are shifted down by NROWS rows;  if
-    FROW = 0 then the blank rows are inserted at the beginning of the
-    table.  Note that it is *not* necessary to insert rows in a table before
-    writing data to those rows (indeed, it would be inefficient to do so).
-    Instead one may simply write data to any row of the table, whether that
-    row of data already exists or not.
-    
-    The first delete routine deletes NROWS consecutive rows
-    starting with row FIRSTROW.  The second delete routine takes an
-    input string that lists the rows or row ranges (e.g.,
-    '5-10,12,20-30'), whereas the third delete routine takes an input
-    integer array that specifies each individual row to be deleted. In
-    both latter cases, the input list of rows to delete must be sorted
-    in ascending order.  These routines update the NAXIS2 keyword to
-    reflect the new number of rows in the
->   table. \label{ffirow} \label{ffdrow} \label{ffdrws} \label{ffdrrg}

-
-  int fits_delete_rowlistll / ffdrwsll
-      (fitsfile *fptr, LONGLONG *rowlist, LONGLONG nrows, > int *status)
--
->2  Insert or delete column(s) in an ASCII or binary
-    table.  When inserting, COLNUM specifies the column number that the
-    (first) new column should occupy in the table.  NCOLS specifies how
-    many columns are to be inserted. Any existing columns from this
-    position and higher are shifted over to allow room for the new
-    column(s).  The index number on all the following keywords will be
-    incremented or decremented if necessary to reflect the new position
-    of the column(s) in the table:  TBCOLn, TFORMn, TTYPEn, TUNITn,
-    TNULLn, TSCALn, TZEROn, TDISPn, TDIMn, TLMINn, TLMAXn, TDMINn,
-    TDMAXn, TCTYPn, TCRPXn, TCRVLn, TCDLTn, TCROTn,

-       char **tform, > int *status)
-
-  int fits_delete_col / ffdcol(fitsfile *fptr, int colnum, > int *status)
--
->3  Copy a column from one HDU to another (or to the same HDU).  If
-    create\_col = TRUE, then a new column will be inserted in the output
-    table, at position `outcolumn', otherwise the existing output column will
-    be overwritten (in which case it must have a compatible data type).
-    If outcolnum is greater than the number of column in the table, then
-    the new column will be appended to the end of the table.  
-    Note that the first column in a table is at colnum = 1. 
-    The standard indexed keywords that related to the column (e.g., TDISPn,
->   TUNITn, TCRPXn, TCDLTn, etc.) will also be copied. \label{ffcpcl}

->4  Copy 'nrows' consecutive rows from one table to another, beginning
-    with row 'firstrow'.  These rows will be appended to any existing
-    rows in the output table.

-      (fitsfile *infptr, fitsfile *outfptr, LONGLONG firstrow,

->5  Modify the vector length of a binary table column (e.g.,
-    change a column from TFORMn = '1E' to '20E').  The vector
->   length may be increased or decreased from the current value. \label{ffmvec}

--
-***4.  Read and Write Column Data Routines 
-
-The following routines write or read data values in the current ASCII
-or binary table extension.  If a write operation extends beyond the
-current size of the table, then the number of rows in the table will
-automatically be increased and the NAXIS2 keyword value will be
-updated.  Attempts to read beyond the end of the table will result in
-an error.
-
-Automatic data type conversion is performed for numerical data types
-(only) if the data type of the column (defined by the TFORMn keyword)
-differs from the data type of the array in the calling routine.  ASCII and binary
-tables support the following data type values:  TSTRING, TBYTE, TSBYTE, TSHORT,
-TUSHORT, TINT, TUINT, TLONG, TLONGLONG, TULONG, TFLOAT, or TDOUBLE.
-Binary tables also support TLOGICAL (internally mapped to the `char'
-data type), TCOMPLEX, and TDBLCOMPLEX.
-
-Note that it is *not* necessary to insert rows in a table before
-writing data to those rows (indeed, it would be inefficient to do so).
-Instead, one may simply write data to any row of the table, whether that
-row of data already exists or not.
-
-Individual bits in a binary table 'X' or 'B' column may be read/written 
-to/from a *char array by specifying the TBIT datatype.  The *char 
-array will be interpreted as an array of logical TRUE (1) or FALSE (0)
-values that correspond to the value of each bit in the FITS 'X' or 'B' column.
-Alternatively, the values in a binary table 'X' column may be read/written
-8 bits at a time to/from an array of 8-bit integers by specifying the 
-TBYTE datatype.
-
-Note that within the context of these routines, the TSTRING data type
-corresponds to a C 'char**' data type, i.e., a pointer to an array of
-pointers to an array of characters.  This is different from the keyword
-reading and writing routines where TSTRING corresponds to a C 'char*'
-data type, i.e., a single pointer to an array of characters.  When
-reading strings from a table, the char arrays obviously must have been
-allocated long enough to hold the whole FITS table string.
-
-Numerical data values are automatically scaled by the TSCALn and TZEROn
-keyword values (if they exist).
-
-In the case of binary tables with vector elements, the 'felem'
-parameter defines the starting element (beginning with 1, not 0) within
-the cell (a cell is defined as the intersection of a row and a column
-and may contain a single value or a vector of values).  The felem
-parameter is ignored when dealing with ASCII tables. Similarly, in the
-case of binary tables the 'nelements' parameter specifies the total
-number of vector values to be read or written (continuing on subsequent
-rows if required) and not the number of table cells.
-
->>1  Write elements into an ASCII or binary table column.
-   The first routine simply writes the array of values to the FITS file
-   (doing data type conversion if necessary) whereas the second routine
-   will substitute the  appropriate FITS null value for all elements
-   which are equal to the input value of nulval (note that this
-   parameter gives the address of nulval, not the null value
-   itself).  For integer columns the FITS null value is defined by the
-   TNULLn keyword (an error is returned if the keyword doesn't exist).
-   For floating point columns  the special IEEE NaN (Not-a-Number)
-   value will be written into the FITS file.  If a null pointer is
-   entered for nulval, then the null value is ignored and this routine
-   behaves the same as the first routine.  The third routine
-   simply writes undefined pixel values to the column.  The fourth routine
-   fills every column in the table with null values, in the specified
-   rows (ignoring any columns that do not have a defined null value).

-       (fitsfile *fptr, LONGLONG firstrow, LONGLONG nelements, > int *status)
--
->2  Read elements from an ASCII or binary table column.  The data type
-    parameter specifies the data type of the `nulval' and `array'  pointers;
-    Undefined array elements will be returned with a value = *nullval,
-    (note that this parameter gives the address of the null value, not the
-    null value itself) unless nulval = 0 or *nulval = 0, in which case
-    no checking for undefined pixels will be performed.  The second
-    routine is similar except that any undefined pixels will have the
-    corresponding nullarray element set equal to TRUE (= 1).
-
-    Any column, regardless of it's intrinsic data type, may be read as a
-    string.  It should be noted however that reading a numeric column
-    as a string is 10 - 100 times slower than reading the same column
-    as a number due to the large overhead in constructing the formatted
-    strings.  The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    data type of the column.  The length of the returned strings (not
-    including the null terminating character) can be determined with
-    the fits\_get\_col\_display\_width routine.  The following TDISPn
-    display formats are currently supported:
--
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
--
-    where w is the width in characters of the displayed values, m is the minimum

-***5.  Row Selection and Calculator Routines 
-
-These routines all parse and evaluate an input string containing a user
-defined arithmetic expression.  The first 3 routines select rows in a
-FITS table, based on whether the expression evaluates to true (not
-equal to zero) or false (zero).  The other routines evaluate the
-expression and calculate a value for each row of the table.  The
-allowed expression syntax is described in the row filter section in the
-`Extended File Name Syntax' chapter of this document.  The expression
-may also be written to a text file, and the name of the file, prepended
-with a '@' character may be supplied for the 'expr' parameter (e.g.
-'@filename.txt'). The  expression  in  the  file can be arbitrarily
-complex and extend over multiple lines of the file.  Lines  that begin
-with 2 slash characters ('//') will  be ignored and may be used to add
-comments to the file.
-
->1  Evaluate a boolean expression over the indicated rows, returning an     
- array of flags indicating which rows evaluated to TRUE/FALSE.

-files are not the same, copy the TRUE rows to the output file; if the output

-the results, cast as datatype (TSHORT, TDOUBLE, etc), in array.  If      
-nulval==NULL, UNDEFs will be zeroed out.  For vector results, the number 
-of elements returned may be less than nelements if nelements is not an

->5 Evaluate an expression and write the result either to a column (if
-the expression is a function of other columns in the table) or to a
-keyword (if the expression evaluates to a constant and is not a
-function of other columns in the table).  In the former case, the
-parName parameter is the name of the column (which may or may not already
-exist) into which to write the results, and parInfo contains an
-optional TFORM keyword value if a new column is being created.  If a
-TFORM value is not specified then a default format will be used,
-depending on the expression.  If the expression evaluates to a constant,
-then the result will be written to the keyword name given by the
-parName parameter, and the parInfo parameter may be used to supply an
-optional comment for the keyword.  If the keyword does not already
-exist, then the name of the keyword must be preceded with a '\#' character,
-> otherwise the result will be written to a column with that name. \label{ffcalc}

-***6.  Column Binning or Histogramming Routines
-
-The following routines may be useful when performing histogramming operations on 
-column(s) of a table to generate an image in a primary array or image extension.
-
->1   Calculate the histogramming parameters (min, max, and bin size 
-for each axis of the histogram, based on a variety of possible input parameters.
-If the input names of the columns to be binned are null, then the routine will first
-look for the CPREF = "NAME1, NAME2, ..." keyword which lists the preferred
-columns.  If not present, then the routine will assume the column names X, Y, Z, and T
-for up to 4 axes (as specified by the NAXIS parameter).
-
-MININ and MAXIN are input arrays that give the minimum and maximum value for
-the histogram, along each axis.  Alternatively, the name of keywords that give
-the min, max, and binsize may be give with the MINNAME, MAXNAME, and BINNAME
-array parameters.  If the value = DOUBLENULLVALUE and no keyword names are
-given,  then the routine will use the TLMINn and TLMAXn keywords, if present, or the 
-actual min and/or max values in the column.
-
-BINSIZEIN is an array giving the binsize along each axis.  
-If the value =
-DOUBLENULLVALUE, and a keyword name is not specified with BINNAME, 
-then this routine will first look for the TDBINn keyword, or else will
-use a binsize = 1, or a binsize that produces 10 histogram bins, which ever
-is smaller.

--
-
->2  Copy the relevant keywords from the header of the table that is being
-binned, to the the header of the output histogram image.  This will not
-copy the table structure keywords (e.g., NAXIS, TFORMn, TTYPEn, etc.) nor
-will it copy the keywords that apply to other columns of the table that are
-not used to create the histogram.  This routine will translate the names of
-the World Coordinate System (WCS) keywords for the binned columns into the
-form that is need for a FITS image (e.g., the TCTYPn table keyword will
-be translated to the CTYPEn image keyword).

-**H.  Utility Routines
-
-***1.  File Checksum Routines 
- 
-The following routines either compute or validate the checksums for the
-CHDU.  The DATASUM keyword is used to store the numerical value of the
-32-bit, 1's complement checksum for the data unit alone.  If there is
-no data unit then the value is set to zero. The numerical value is
-stored as an ASCII string of digits, enclosed in quotes, because the
-value may be too large to represent as a 32-bit signed integer.  The
-CHECKSUM keyword is used to store the ASCII encoded COMPLEMENT of the
-checksum for the entire HDU.  Storing the complement, rather than the
-actual checksum, forces the checksum for the whole HDU to equal zero.
-If the file has been modified since the checksums were computed, then
-the HDU checksum will usually not equal zero.  These checksum keyword
-conventions are based on a paper by Rob Seaman published in the
-proceedings of the ADASS IV conference in Baltimore in November 1994
-and a later revision in June 1995.  See Appendix B for the definition
-of the parameters used in these routines.
- 
->1  Compute and write the DATASUM and CHECKSUM keyword values for the CHDU
-    into the current header.  If the keywords already exist, their values
-    will be updated only if necessary (i.e., if the file
-    has been modified since the original keyword
->   values were computed). \label{ffpcks}
--
-  int fits_write_chksum / ffpcks
-      (fitsfile *fptr, > int *status)
--
->2  Update the CHECKSUM keyword value in the CHDU, assuming that the
-    DATASUM keyword exists and already has the correct value.  This routine
-    calculates the new checksum for the current header unit, adds it to the
-    data unit checksum, encodes the value into an ASCII string, and writes
->   the string to the CHECKSUM keyword. \label{ffupck}
--
-  int fits_update_chksum / ffupck
-      (fitsfile *fptr, > int *status)
--
->3  Verify the CHDU by computing the checksums and comparing
-    them with the keywords.  The data unit is verified correctly
-    if the computed checksum equals the value of the DATASUM
-    keyword.  The checksum for the entire HDU (header plus data unit) is
-    correct if it equals zero.  The output DATAOK and HDUOK parameters
-    in this routine are integers which will have a value = 1
-    if the data or HDU is verified correctly, a value = 0
-    if the DATASUM or CHECKSUM keyword is not present, or value = -1
->   if the computed checksum is not correct. \label{ffvcks}
--
-  int fits_verify_chksum / ffvcks
-      (fitsfile *fptr, > int *dataok, int *hduok, int *status)
--
->4  Compute and return the checksum values for the CHDU
-    without creating or modifying the
-    CHECKSUM and DATASUM keywords.  This routine is used internally by
->   ffvcks, but may be useful in other situations as well. \label{ffgcks}
--
-  int fits_get_chksum/ /ffgcks
-      (fitsfile *fptr, > unsigned long *datasum, unsigned long *hdusum,
-       int *status)
--
->5  Encode a checksum value 
-    into a 16-character string.  If complm is non-zero (true) then the 32-bit
->   sum value will be complemented before encoding. \label{ffesum}
--
-  int fits_encode_chksum / ffesum
-      (unsigned long sum, int complm, > char *ascii);
--
->6  Decode a 16-character checksum string into a unsigned long value.
-    If is non-zero (true). then the 32-bit sum value will be complemented
-    after decoding.  The checksum value is also returned as the 
->   value of the function. \label{ffdsum}

-***2.  Date and Time Utility Routines 
-
-The following routines help to construct or parse the FITS date/time
-strings.   Starting in the year 2000, the FITS DATE keyword values (and
-the values of other `DATE-' keywords) must have the form 'YYYY-MM-DD'
-(date only) or 'YYYY-MM-DDThh:mm:ss.ddd...' (date and time) where the
-number of decimal places in the seconds value is optional.  These times
-are in UTC.  The older 'dd/mm/yy' date format may not be used for dates
-after 01 January 2000.  See Appendix B for the definition of the
-parameters used in these routines.
-
->1  Get the current system date.  C already provides standard
-    library routines for getting the current date and time,
-    but this routine is provided for compatibility with
-    the Fortran FITSIO library.  The returned year has 4 digits
->    (1999, 2000, etc.) \label{ffgsdt}
--
-  int fits_get_system_date/ffgsdt
-      ( > int *day, int *month, int *year, int *status )
--
-
->2  Get the current system date and time string ('YYYY-MM-DDThh:mm:ss').
-The time will be in UTC/GMT if available, as indicated by a returned timeref 
-value = 0.  If the returned value of timeref = 1 then this indicates that
-it was not possible to convert the local time to UTC, and thus the local
->time was returned.
--
-  int fits_get_system_time/ffgstm
-      (> char *datestr, int  *timeref, int *status)
--
-
->3  Construct a date string from the input date values.  If the year
-is between 1900 and 1998, inclusive, then the returned date string will
-have the old FITS format ('dd/mm/yy'), otherwise the date string will
-have the new FITS format ('YYYY-MM-DD').  Use fits\_time2str instead
-> to always return a date string using the new FITS format. \label{ffdt2s}
--
-  int fits_date2str/ffdt2s   
-      (int year, int month, int day, > char *datestr, int *status)
--
-
->4  Construct a new-format date + time string ('YYYY-MM-DDThh:mm:ss.ddd...').
-  If the year, month, and day values all = 0 then only the time is encoded
-  with format 'hh:mm:ss.ddd...'.  The decimals parameter specifies how many
-  decimal places of fractional seconds to include in the string.  If `decimals'
-> is negative, then only the date will be return ('YYYY-MM-DD').
--
-  int fits_time2str/fftm2s   
-      (int year, int month, int day, int hour, int minute, double second,
-      int decimals, > char *datestr, int *status)
--
-
->5  Return the date as read from the input string, where the string may be
-in either the old ('dd/mm/yy')  or new ('YYYY-MM-DDThh:mm:ss' or
-'YYYY-MM-DD') FITS format.  Null pointers may be supplied for any
->  unwanted output date parameters.
--
-  int fits_str2date/ffs2dt 
-      (char *datestr, > int *year, int *month, int *day, int *status)
--
-
->6  Return the date and time as read from the input string, where the
-string may be in either the old  or new FITS format.  The returned hours,
-minutes, and seconds values will be set to zero if the input string
-does not include the time ('dd/mm/yy' or 'YYYY-MM-DD') .  Similarly,
-the returned year, month, and date values will be set to zero if the
-date is not included in the input string ('hh:mm:ss.ddd...').  Null
-pointers may be supplied for any unwanted output date and time
->parameters.
--
-  int fits_str2time/ffs2tm 
-      (char *datestr, > int *year, int *month, int *day, int *hour,
-      int *minute, double *second, int *status)
--
-
-***3.  General Utility Routines 
- 
-The following utility routines may be useful for certain applications.
-
->1  Return the revision number of the CFITSIO library.
-    The revision number will be incremented with each new
->   release of CFITSIO. \label{ffvers}
--
-  float fits_get_version / ffvers ( > float *version)
--
->2  Write an 80-character message to the CFITSIO error stack.  Application
-    programs should not normally write to the stack, but there may be
->   some situations where this is desirable. \label{ffpmsg}
--
-  void fits_write_errmsg / ffpmsg (char *err_msg)
--
->>3  Convert a character string to uppercase (operates in place). \label{ffupch}
--
-  void fits_uppercase / ffupch (char *string)
--
->4  Compare the input template string against the reference string
-    to see if they match.  The template string may contain wildcard
-    characters: '*' will match any sequence of characters (including
-    zero characters) and '?' will match any single character in the
-    reference string.  The '\#' character will match any consecutive string
-    of decimal digits (0 - 9).  If casesen = CASESEN = TRUE then the match will
-    be case sensitive, otherwise the case of the letters will be ignored
-    if casesen = CASEINSEN = FALSE.  The returned MATCH parameter will be 
-    TRUE if the 2 strings match, and EXACT will be TRUE if the match is
-    exact (i.e., if no wildcard characters were used in the match).
->   Both strings must be 68 characters or less in length. \label{ffcmps}
--
-  void fits_compare_str / ffcmps
-       (char *templt, char *string, int casesen, > int *match, int *exact)
--
->5 Split a string containing a list of names (typically file names or column 
-   names) into individual name tokens by a sequence of calls to
-   fits\_split\_names.  The names in the list must be delimited by a comma
-   and/or spaces.  This routine ignores spaces and commas that occur
-   within parentheses, brackets, or curly brackets.  It also strips any
-   leading and trailing blanks from the returned name.
-
-   This routine is similar to the ANSI C 'strtok' function:
-
-   The first call to fits\_split\_names has a non-null input string.
-   It finds the first name in the string and terminates it by overwriting
-   the next character of the string with a null terminator and returns a
-   pointer to the name.  Each subsequent call, indicated by a NULL value
-   of the input string, returns the next name, searching from just past
-   the end of the previous name.  It returns NULL when no further names
->  are found.  \label{splitnames}
--
-   char *fits_split_names(char *namelist) 
--
-   The following example shows how a string would be split into 3 names:
--
-    myfile[1][bin (x,y)=4], file2.fits  file3.fits
-    ^^^^^^^^^^^^^^^^^^^^^^  ^^^^^^^^^^  ^^^^^^^^^^
-        1st name             2nd name    3rd name
--
->6  Test that the keyword name contains only legal characters (A-Z,0-9,
-    hyphen, and underscore) or that the keyword record contains only legal
->   printable ASCII characters  \label{fftkey} \label{fftrec}
--
-  int fits_test_keyword / fftkey (char *keyname, > int *status)
-
-  int fits_test_record / fftrec (char *card, > int *status)
--
->7  Test whether the current header contains any NULL (ASCII 0) characters.
-    These characters are illegal in the header, but they will go undetected
-    by most of the CFITSIO keyword header routines, because the null is 
-    interpreted as the normal end-of-string terminator.  This routine returns
-    the position of the first null character in the header, or zero if there
-    are no nulls.  For example a returned value of 110 would indicate that
-    the first NULL is located in the 30th character of the second keyword
-    in the header (recall that each header record is 80 characters long).
-    Note that this is one of the few CFITSIO routines in which the returned
->    value is not necessarily equal to the status value).   \label{ffnchk}
--
-  int fits_null_check / ffnchk (char *card, > int *status)
--
->8  Parse a header keyword record and return the name of the keyword,
-    and the length of the name.
-    The keyword name normally occupies the first 8 characters of the
-    record, except under the HIERARCH convention where the name can
->   be up to 70 characters in length. \label{ffgknm}
--
-  int fits_get_keyname / ffgknm
-      (char *card, > char *keyname, int *keylength, int *status)
--
->9  Parse a header keyword record, returning the value (as
-    a literal character string) and comment strings.  If the keyword has no
-    value (columns 9-10 not equal to '= '), then a null value string is 
-    returned and the comment string is set equal to column 9 - 80 of the
->   input string. \label{ffpsvc}
--
-  int fits_parse_value / ffpsvc
-      (char *card, > char *value, char *comment, int *status)
--
->10 Construct an array indexed keyword name (ROOT + nnn).
-    This routine appends the sequence number to the root string to create
->   a keyword name (e.g., 'NAXIS' + 2 = 'NAXIS2') \label{ffkeyn}
--
-  int fits_make_keyn / ffkeyn
-      (char *keyroot, int value, > char *keyname, int *status)
--
->11  Construct a sequence keyword name (n + ROOT).
-    This routine concatenates the sequence number to the front of the
->   root string to create a keyword name (e.g., 1 + 'CTYP' = '1CTYP') \label{ffnkey}
--
-  int fits_make_nkey / ffnkey
-      (int value, char *keyroot, > char *keyname, int *status)
--
->12 Determine the data type of a keyword value string. This routine
-    parses the keyword value string  to determine its data type. 
-    Returns 'C', 'L', 'I', 'F' or 'X', for character string, logical,
->   integer, floating point, or complex, respectively. \label{ffdtyp}
--
-  int fits_get_keytype / ffdtyp
-      (char *value, > char *dtype, int *status)
--
->13 Determine the integer data type of an integer keyword value string. 
-   The returned datatype value is the minimum integer datatype (starting
-   from top of the following list and working down) required
->  to store the integer value:  
--  
-    Data Type      Range
-     TSBYTE:     -128 to 127
-     TBYTE:       128 to 255
-     TSHORT:     -32768 to 32767
-     TUSHORT:     32768 to 65535

-     TLONGLONG   -9223372036854775808 to 9223372036854775807
--
->    The *neg parameter returns 1 if the input value is

--
-  int fits_get_inttype / ffinttyp
-      (char *value, > int *datatype, int *neg, int *status)
--
->14 Return the class of an input header record.  The record is classified
-    into one of the following categories (the class values are
-    defined in fitsio.h).  Note that this is one of the few CFITSIO
->   routines that does not return a status value. \label{ffgkcl}

-    Fixed decimal point columns (with TFORM = 'Fw.d') are defined to
-    be single precision reals (code = TFLOAT) if w is between 1 and 7 characters
-    wide, inclusive.  Wider 'F' columns will return a double precision
-    data code (= TDOUBLE).  'Ew.d' format columns will have datacode = TFLOAT,

-  int fits_parse_template / ffgthd
-      (char *templt, > char *card, int *keytype, int *status)
--
-    The input templt character string generally should contain 3 tokens:
-    (1) the KEYNAME, (2) the VALUE, and (3) the COMMENT string.  The
-    TEMPLATE string must adhere to the following format:
- 
->-      The KEYNAME token must begin in columns 1-8 and be a maximum  of 8
-        characters long.  A legal FITS keyword name may only
-        contain the characters A-Z, 0-9, and '-' (minus sign) and
-        underscore.  This routine will automatically convert any lowercase
-        characters to uppercase in the output string.  If the first 8 characters 
-        of the template line are
-        blank then the remainder of the line is considered to be a FITS comment
->       (with a blank keyword name).  
- 
->-      The VALUE token must be separated from the KEYNAME token by one or more
-        spaces and/or an '=' character.  The data type of the VALUE token
-        (numeric, logical, or character string) is automatically determined
-        and  the output CARD string is formatted accordingly.  The value
-        token may be forced to be interpreted as a string (e.g. if it is a
-        string of numeric digits) by enclosing it in single quotes.
-        If the value token is a character string that contains 1 or more 
-        embedded blank space characters or slash ('/') characters then the 
->       entire character string must be enclosed in single quotes.
- 
->-      The COMMENT token is optional, but if present must be separated from
->       the VALUE token by a blank space or a  '/' character.
- 
->-      One exception to the above rules is that if the first non-blank
-        character in the first 8 characters of the template string is a 
-        minus sign ('-') followed
-        by a single token, or a single token followed by an equal sign,
-        then it is interpreted as the name of a keyword which is to be
->       deleted from the FITS header.
- 
->-      The second exception is that if the template string starts with
-        a minus sign and is followed by 2 tokens (without an equals sign between
-        them) then the second token
-        is interpreted as the new name for the keyword specified by
-        first token.  In this case the old keyword name (first token)
-        is returned in characters 1-8 of the returned CARD string, and
-        the new keyword name (the second token) is returned in characters
-        41-48 of the returned CARD string.  These old and new names
-        may then be passed to the ffmnam routine which will change
->       the keyword name.
- 
-    The keytype output parameter indicates how the returned CARD string
-    should be interpreted:
--
-        keytype                  interpretation
-        -------          -------------------------------------------------
-           -2            Rename the keyword with name = the first 8 characters of CARD
-                         to the new name given in characters 41 - 48 of CARD.
- 
-           -1            delete the keyword with this name from the FITS header.
- 
-            0            append the CARD string to the FITS header if the
-                         keyword does not already exist, otherwise update
-                         the keyword value and/or comment field if is already exists.
- 
-            1            This is a HISTORY or COMMENT keyword; append it to the header
- 
-            2            END record; do not explicitly write it to the FITS file.

-     EXAMPLES:  The following lines illustrate valid input template strings:

-      RVAL           34.6   /     This is a floating point keyword
-      EVAL=-12.45E-03  / This is a floating point keyword in exponential notation
-      lval F / This is a boolean keyword
-                  This is a comment keyword with a blank keyword name
-      SVAL1 = 'Hello world'   /  this is a string keyword
-      SVAL2  '123.5'  this is also a string keyword
-      sval3  123+  /  this is also a string keyword with the value '123+    '

->19  Translate a keyword name into a new name, based on a set of patterns.
-This routine is useful for translating keywords in cases such as 
-adding or deleting columns in
-a table, or copying a column from one table to another, or extracting
-an array from a cell in a binary table column into an image extension.  In 
-these cases, it is necessary to translate the names of the keywords associated
-with the original table column(s) into the appropriate keyword name in the final
-file.  For example, if column 2 is deleted from a table, 
-then the value of 'n' in all the
-TFORMn and TTYPEn keywords for columns 3 and higher must be decremented
-by 1.  Even more complex translations are sometimes needed to convert the 
-WCS keywords when extracting an image out of a table column cell into
-a separate image extension.
-
-The user passes an array of patterns to be matched.  Input pattern
-number i is pattern[i][0], and output pattern number i is
-pattern[i][1].  Keywords are matched against the input patterns.  If a
-match is found then the keyword is re-written according to the output
-pattern.
-
-Order is important.  The first match is accepted.  The fastest match
-will be made when templates with the same first character are grouped
-together.
-
-Several characters have special meanings:
--
-     i,j - single digits, preserved in output template
-     n - column number of one or more digits, preserved in output template
-     m - generic number of one or more digits, preserved in output template
-     a - coordinate designator, preserved in output template
-     # - number of one or more digits
-     ? - any character
-     * - only allowed in first character position, to match all
-         keywords; only useful as last pattern in the list
--
-i, j, n, and m are returned by the routine.
-
-For example, the input pattern "iCTYPn" will match "1CTYP5" (if n\_value
-is 5); the output pattern "CTYPEi" will be re-written as "CTYPE1".
-Notice that "i" is preserved.
-
-The following output patterns are special:
-
-    "-" - do not copy a keyword that matches the corresponding input pattern
-
-    "+" - copy the input unchanged
-
-The inrec string could be just the 8-char keyword name, or the entire 
-80-char header record.  Characters 9 - 80 in the input string simply get
-appended to the translated keyword name.
-
-If n\_range = 0, then only keywords with 'n' equal to n\_value will be 
-considered as a pattern match.  If n\_range = +1, then all values of 
-'n' greater than or equal to n\_value will be a match, and if -1, 
->then values of 'n' less than or equal to n\_value will match.\label{translatekey}

-*VII.  The CFITSIO Iterator Function
-
-The fits\_iterate\_data function in CFITSIO provides a unique method of
-executing an arbitrary user-supplied `work' function that operates on
-rows of data in  FITS tables or on pixels in FITS images.  Rather than
-explicitly reading and writing the FITS images or columns of data, one
-instead calls the CFITSIO iterator routine, passing to it the name of
-the user's work function that is to be executed along with a list of
-all the table columns or image arrays that are to be passed to the work
-function.  The CFITSIO iterator function then does all the work of
-allocating memory for the arrays, reading the input data from the FITS
-file, passing them to the work function, and then writing any output
-data back to the FITS file after the work function exits.  Because
-it is often more efficient to process only a subset of the total table
-rows at one time, the iterator function can determine the optimum
-amount of data to pass in each iteration and repeatedly call the work
-function until the entire table been processed.
-
-For many applications this single CFITSIO iterator function can
-effectively replace all the other CFITSIO routines for reading or
-writing data in FITS images or tables.  Using the iterator has several
-important advantages over the traditional method of reading and writing
-FITS data files:
-
-\begin{itemize}
-\item
-It cleanly separates the data I/O from the routine that operates on
-the data.  This leads to a more modular and `object oriented'
-programming style.  
-
-\item
-It simplifies the application program by eliminating the need to allocate
-memory for the data arrays and eliminates most of the calls to the CFITSIO
-routines that explicitly read and write the data.
-
-\item
-It ensures that the data are processed as efficiently as possible.
-This is especially important when processing tabular data since
-the iterator function will calculate the most efficient number
-of rows in the table to be passed at one time to the user's work 
-function on each iteration.
-
-\item
-Makes it possible for larger projects to develop a library of work
-functions that all have a uniform calling sequence and are all
-independent of the details of the FITS file format.
-
-\end{itemize}
-
-There are basically 2 steps in using the CFITSIO iterator function.
-The first step is to design the work function itself which must have a
-prescribed set of input parameters.  One of these parameters is a
-structure containing pointers to the arrays of data; the work function
-can perform any desired operations on these arrays and does not need to
-worry about how the input data were read from the file or how the
-output data get written back to the file.
-
-The second step is to design the driver routine that opens all the
-necessary FITS files and initializes  the input parameters to the
-iterator function.  The driver program calls the CFITSIO iterator
-function which then reads the data and passes it to the user's work
-function.
-
-The following 2 sections describe these steps in more detail.  There
-are also several example programs included with the CFITSIO
-distribution which illustrate how to use the iterator function.
-
-**A   The Iterator Work Function
-
-The user-supplied iterator work function must have the following set of
-input parameters (the function can be given any desired name):
-
-- 
-  int user_fn( long totaln, long offset, long firstn, long nvalues,
-               int narrays, iteratorCol *data,  void *userPointer )
--
-
-\begin{itemize}
-
-\item
-  totaln -- the total number of table rows or image pixels
-            that will be passed to the work function
-            during 1 or more iterations. 
-
-\item
-  offset     -- the offset applied to the first table row or image
-                pixel to be passed to the work function.  In other
-                words, this is the number of rows or pixels that
-                are skipped over before starting the iterations. If 
-                offset = 0, then all the table rows or image pixels
-                will be passed to the work function.
-
-\item
-  firstn     -- the number of the first table row or image pixel
-                (starting with 1)  that is being passed in this 
-                particular call to the work function.
-
-\item
-  nvalues    -- the number of table rows or image pixels that are
-                being passed in this particular call to the work
-                function.  nvalues will always be less than or
-                equal to totaln and will have the same value on
-                each iteration, except possibly on the last 
-                call which may have a smaller value.
-
-\item
-  narrays     -- the number of arrays of data that are being passed
-                 to the work function.  There is one array for each 
-                 image or table column.      
-
-\item
-  *data   -- array of structures, one for each 
-             column or image.  Each structure contains a pointer
-             to the array of data as well as other descriptive
-             parameters about that array.  
-
-\item
-  *userPointer -- a user supplied pointer that can be used
-                 to pass ancillary information from the driver function
-                 to the work function.
-                 This pointer is passed to the CFITSIO iterator function
-                 which then passes it on to the
-                 work function without any modification.
-                 It may point to a single number, to an array of values,
-                 to a structure containing an arbitrary set of parameters
-                 of different types, 
-                 or it may be a null pointer if it is not needed.
-                 The work function must cast this pointer to the
-                 appropriate data type before using it it.
-\end{itemize}
-
-The totaln, offset, narrays, data, and userPointer parameters are
-guaranteed to have the same value on each iteration.  Only firstn,
-nvalues, and the arrays of data pointed to by the data structures may
-change on each iterative call to the work function.
-
-Note that the iterator treats an image as a long 1-D array of pixels
-regardless of it's intrinsic dimensionality.  The total number of
-pixels is just the product of the size of each dimension, and the order
-of the pixels is the same as the order that they are stored in the FITS
-file. If the work function needs to know the number and size of the
-image dimensions then these parameters can be passed via the
-userPointer structure.
-
-The iteratorCol structure is currently defined as follows:
--
-typedef struct  /* structure for the iterator function column information */
-{  
-   /* structure elements required as input to fits_iterate_data: */
-
-  fitsfile *fptr;       /* pointer to the HDU containing the column or image */
-  int      colnum;      /* column number in the table; ignored for images    */
-  char     colname[70]; /* name (TTYPEn) of the column; null for images      */
-  int      datatype;    /* output data type (converted if necessary) */
-  int      iotype;      /* type: InputCol, InputOutputCol, or OutputCol */
-
-  /* output structure elements that may be useful for the work function: */
-
-  void     *array;    /* pointer to the array (and the null value) */
-  long     repeat;    /* binary table vector repeat value; set     */
-                      /*     equal to 1 for images                 */
-  long     tlmin;     /* legal minimum data value, if any          */

-
-} iteratorCol;
--
-
-Instead of directly reading or writing the elements in this structure,
-it is recommended that programmers use the access functions that are
-provided for this purpose.
-
-The first five elements in this structure must be initially defined by
-the driver routine before calling the iterator routine.  The CFITSIO
-iterator routine uses this information to determine what column or
-array to pass to the work function, and whether the array is to be
-input to the work function, output from the work function, or both.
-The CFITSIO iterator function fills in the values of the remaining
-structure elements before passing it to the work function.
-
-The array structure element is a pointer to the actual data array and
-it must be cast to the correct data type before it is used.  The
-`repeat' structure element give the number of data values in each row
-of the table, so that the total number of data values in the array is
-given by repeat * nvalues.  In the case of image arrays and ASCII
-tables, repeat will always be equal to 1.  When the data type is a
-character string, the array pointer is actually a pointer to an array
-of string pointers (i.e., char **array).  The other output structure
-elements are provided for convenience in case that information is
-needed within the work function.  Any other information may be passed
-from the driver routine to the work function via the userPointer
-parameter.
-
-Upon completion, the work routine must return an integer status value,
-with 0 indicating success and any other value indicating an error which
-will cause the iterator function to immediately exit at that point.  Return status
-values in the range 1 -- 1000 should be avoided since these are
-reserved for use by CFITSIO.  A return status value of -1 may be used to
-force the CFITSIO iterator function to stop at that point and return
-control to the driver routine after writing any output arrays to the
-FITS file.  CFITSIO does not considered this to be an error condition,
-so any further processing by the application program will continue normally.
-
-**B   The Iterator Driver Function
-
-The iterator driver function must open the necessary FITS files and
-position them to the correct HDU.  It must also initialize the following
-parameters in the iteratorCol structure (defined above) for each
-column or image before calling the CFITSIO iterator function.
-Several `constructor' routines are provided in CFITSIO for this
-purpose.
-
-\begin{itemize}
-\item 
-  *fptr --  The fitsfile pointer to the table or image.
-\item
-colnum -- the number of the column in the table.  This value is ignored
-          in the case of images.  If colnum equals 0, then the column name
-          will be used to identify the column to be passed to the
-          work function.
-
-\item
-colname -- the name (TTYPEn keyword) of the column.  This is
-           only required if colnum = 0 and is ignored for images.
-\item
-datatype -- The desired data type of the array to be passed to the
-            work function.  For numerical data the data type does
-            not need to be the same as the actual data type in the
-            FITS file, in which case CFITSIO will do the conversion.
-            Allowed values are: TSTRING, TLOGICAL, TBYTE, TSBYTE, TSHORT, TUSHORT, 
-            TINT, TLONG, TULONG, TFLOAT, TDOUBLE.  If the input
-            value of data type equals 0, then the  existing
-            data type of the column or image will be used without
-            any conversion.
-
-\item
-iotype -- defines whether the data array is to be input to the
-          work function (i.e, read from the FITS file), or output
-          from the work function (i.e., written to the FITS file) or
-          both.  Allowed values are InputCol, OutputCol, or InputOutputCol.
-	  Variable-length array columns are supported as InputCol or 
-	  InputOutputCol types, but may not be used for an OutputCol type.
-\end{itemize}
-
-After the driver routine has initialized all these parameters, it
-can then call the CFITSIO iterator function:
-
--
-  int fits_iterate_data(int narrays, iteratorCol *data, long offset,
-      long nPerLoop, int (*workFn)( ), void *userPointer, int *status);
--
-
-\begin{itemize}
-\item
-
-   narrays    -- the number of columns or images that are to be passed
-                 to the work function.  
-\item
-   *data --     pointer to array of structures containing information 
-                about each column or image.
-
-\item
-   offset      -- if positive, this number of rows at the
-                      beginning of the table (or pixels in the image) 
-                      will be skipped and will not be passed to the work
-                      function.
-
-\item
-   nPerLoop   - specifies the number of table rows (or number of
-                    image pixels) that are to be passed to the work
-                    function on each iteration.  If nPerLoop = 0
-                    then CFITSIO will calculate the optimum number
-                    for greatest efficiency.
-                    If nPerLoop is negative, then all the rows
-                    or pixels will be passed at one time, and the work
-                    function will only be called once.  If any variable
-		    length arrays are being processed, then the nPerLoop
-		    value is ignored, and the iterator will always process
-		    one row of the table at a time.
-
-\item
-   *workFn     - the name (actually the address) of the work function
-                 that is to be called by fits\_iterate\_data.
-
-\item
-   *userPointer - this is a user supplied pointer that can be used
-                  to pass ancillary information from the driver routine
-                  to the work function.  It may point to a single number,
-                  an array, or to a structure containing an arbitrary set
-                  of parameters.
-
-\item
-   *status      - The CFITSIO error status.  Should = 0 on input;
-                  a non-zero output value indicates an error.
-\end{itemize}
-
-When fits\_iterate\_data is called it first allocates memory to hold
-all the requested columns of data or image pixel arrays.  It then reads
-the input data from the FITS tables or images into the arrays then
-passes the structure with pointers to these data arrays to the work
-function.  After the work function returns, the iterator function
-writes any output columns of data or images back to the FITS files.  It
-then repeats this process for any remaining sets of rows or image
-pixels until it has processed the entire table or image or until the
-work function returns a non-zero status value.  The iterator then frees
-the memory that it initially allocated and returns control to the
-driver routine that called it.
-
-**C.  Guidelines for Using the Iterator Function
-
-The totaln, offset, firstn, and nvalues parameters that are passed to
-the work function are useful for determining how much of the data has
-been processed and how much remains left to do.  On the very first call
-to the work function firstn will be equal to offset + 1;  the work
-function may need to perform various initialization tasks before
-starting to  process the data. Similarly, firstn + nvalues - 1 will be
-equal to totaln on the last iteration, at which point the work function
-may need to perform some clean up operations before exiting for the
-last time.  The work function can also force an early termination of
-the iterations by returning a status value = -1.
-
-The narrays and iteratorCol.datatype arguments allow the work function
-to double check that the number of input arrays and their data types
-have the expected values.  The iteratorCol.fptr and iteratorCol.colnum
-structure elements can be used if the work function needs to read or
-write the values of other keywords in the FITS file associated with
-the array.  This should generally only be done during the
-initialization step or during the clean up step after the last set of
-data has been processed.  Extra FITS file I/O during the main
-processing loop of the work function can seriously degrade the speed of
-the program.
-
-If variable-length array columns are being processed, then the iterator
-will operate on one row of the table at a time.  In this case the
-the repeat element in the interatorCol structure will be set equal to
-the number of elements in the current row that is being processed.
-
-One important feature of the iterator is that the first element in each
-array that is passed to the work function gives the value that is used
-to represent null or undefined values in the array.  The real data then
-begins with the second element of the array (i.e., array[1], not
-array[0]).  If the first array element is equal to zero, then this
-indicates that all the array elements have defined values and there are
-no undefined values.  If array[0] is not equal to zero, then this
-indicates that some of the data values are undefined and this value
-(array[0]) is used to represent them.  In the case of output arrays
-(i.e., those arrays that will be written back to the FITS file by the
-iterator function after the work function exits) the work function must
-set the first array element to the desired null value if necessary,
-otherwise the first element should be set to zero to indicate that
-there are no null values in the output array.  CFITSIO defines 2
-values, FLOATNULLVALUE and DOUBLENULLVALUE, that can be used as default
-null values for float and double data types, respectively.  In the case
-of character string data types, a null string is always used to
-represent undefined strings.
-
-In some applications it may be necessary to recursively call the iterator
-function.  An example of this is given by one of the example programs
-that is distributed with CFITSIO: it first calls a work function that
-writes out a 2D histogram image.  That work function in turn calls
-another work function that reads the  `X' and `Y' columns in a table to
-calculate the value of each 2D histogram image pixel. Graphically, the
-program structure can be described as:
--
- driver --> iterator --> work1_fn --> iterator --> work2_fn
--
-
-Finally, it should be noted that the table columns or image arrays that
-are passed to the work function do not all have to come from the same
-FITS file and instead may come from any combination of sources as long
-as they have the same length.   The length of the first table column or
-image array is used by the iterator if they do not all have the same
-length.

-    respectively.  The last 2 routines allow all the parameters
-    to be set with one function call (one supplies the column
->   name, the other the column number). \label{ffiterset}

-*IX.  World Coordinate System Routines
-
-The FITS community has adopted a set of keyword conventions that define
-the transformations needed to convert between pixel locations in an
-image and the corresponding celestial coordinates on the sky, or more
-generally, that define world coordinates that are to be associated with
-any pixel location in an n-dimensional FITS array. CFITSIO is distributed
-with a a few self-contained World Coordinate System (WCS) routines,
-however, these routines DO NOT support all the latest WCS conventions,
-so it is STRONGLY RECOMMENDED that software developers use a more robust
-external WCS library.  Several recommended libraries are:
-
--
-  WCSLIB -  supported by Mark Calabretta
-  WCSTools - supported by Doug Mink
-  AST library - developed by the U.K. Starlink project
--
-
-More information about the WCS keyword conventions and links to all of
-these WCS libraries can be found on the FITS Support Office web site at
-http://fits.gsfc.nasa.gov under the WCS link.
-
-The functions provided in these external WCS libraries will need
-access to the  WCS keywords contained in the FITS file headers.
-One convenient way to pass this information to the external library is
-to use the fits\_hdr2str routine in CFITSIO (defined below) to copy the
-header keywords into one long string, and then pass this string to an
-interface routine in the external library that will extract
-the necessary WCS information (e.g., the 'wcspih' routine in the WCSLIB
-library and the 'astFitsChan' and 'astPutCards' functions in the AST 
-library).
-  
->1  Concatenate the header keywords in the CHDU into a single long
-    string of characters. Each 80-character fixed-length keyword
-    record is appended to the output character string, in order, with
-    no intervening separator or terminating characters. The last header
-    record is terminated with a NULL character.  This routine allocates
-    memory for the returned character array, so the calling program must
-    free the memory when finished.
-
-    There are 2 related routines: fits\_hdr2str simply concatenates all
-    the existing keywords in the header; fits\_convert\_hdr2str is similar,
-    except that if the CHDU is a tile compressed image (stored in a binary
-    table) then it will first convert that header back to that of a 
-    normal FITS image before concatenating the keywords.
-
-    Selected keywords may be excluded from the returned character string.
-    If the second parameter (nocomments) is TRUE (nonzero) then any
-    COMMENT, HISTORY, or blank keywords in the header will not be copied
-    to the output string.
-
-    The 'exclist' parameter may be used to supply a list of keywords
-    that are to be excluded from the output character string. Wild card
-    characters (*, ?, and \#) may be used in the excluded keyword names.
-    If no additional keywords are to be excluded, then set nexc = 0 and
->   specify NULL for the the **exclist  parameter.  \label{hdr2str}
--
-  int fits_hdr2str
-      (fitsfile *fptr, int nocomments, char **exclist, int nexc,

-
->2   The following CFITSIO routine is specifically designed for use
-in conjunction with the WCSLIB library.  It is not expected that
-applications programmers will call this routine directly, but it
-is documented here for completeness.  This routine extracts arrays
-from a binary table that contain WCS information using the -TAB table
-lookup convention.  See the documentation provided with the WCSLIB 
-> library for more information.  \label{wcstab}

-**A.   Self-contained WCS Routines
-
-The following routines DO NOT support the more recent WCS conventions
-that have been approved as part of the FITS standard.  Consequently,
-the following routines ARE NOW DEPRECATED.  It is STRONGLY RECOMMENDED
-that software developers not use these routines, and instead use an
-external WCS library, as described in the previous section.
-
-These routines are included mainly for backward compatibility with
-existing software.  They support the following standard map 
-projections: -SIN, -TAN, -ARC, -NCP, -GLS, -MER, and -AIT (these are the
-legal values for the coordtype parameter).  These routines are based
-on similar functions in Classic AIPS.  All the angular quantities are
-given in units of degrees.
-
->1  Get the values of the basic set of standard FITS celestial coordinate
-    system keywords from the header of a FITS image (i.e., the primary
-    array or an IMAGE extension).  These values may then be passed to
-    the fits\_pix\_to\_world and fits\_world\_to\_pix routines that
-    perform the coordinate transformations.  If any or all of the WCS
-    keywords are not present, then default values will be returned. If
-    the first coordinate axis is the declination-like coordinate, then
-    this routine will swap them so that the longitudinal-like coordinate
-    is returned as the first axis.  
-    
-    The first routine (ffgics) returns
-    the primary WCS, whereas the second routine returns the particular
-    version of the WCS specified by the 'version' parameter, which much
-    be a character ranging from 'A' to 'Z' (or a blank character, which is
-    equivalent to calling ffgics).
-
-    If the file uses the newer 'CDj\_i' WCS transformation matrix
-    keywords instead of old style 'CDELTn' and 'CROTA2' keywords, then
-    this routine will calculate and return the values of the equivalent
-    old-style keywords.  Note that the conversion from the new-style
-    keywords to the old-style values is sometimes only an
-    approximation, so if the approximation is larger than an internally
-    defined threshold level, then CFITSIO will still return the
-    approximate WCS keyword values, but will also return with status =
-    APPROX\_WCS\_KEY, to warn the calling program that approximations
-    have been made.  It is then up to the calling program to decide
-    whether the approximations are sufficiently accurate for the
-    particular application, or whether more precise WCS transformations
->   must be performed using new-style WCS keywords directly. \label{ffgics}

-*VIII  Hierarchical Grouping Routines
-
-These functions allow for the creation and manipulation of FITS HDU
-Groups, as defined in "A Hierarchical Grouping Convention for FITS" by
-Jennings, Pence, Folk and Schlesinger:
- 
-http://fits.gsfc.nasa.gov/group.html
-
-A group is a
-collection of HDUs whose association is defined by a {\it grouping
-table}.  HDUs which are part of a group are referred to as {\it member
-HDUs} or simply as {\it members}. Grouping table member HDUs may
-themselves be grouping tables, thus allowing for the construction of
-open-ended hierarchies of HDUs.
-
-Grouping tables contain one row for each member HDU. The grouping table
-columns provide identification information that allows applications to
-reference or "point to" the member HDUs. Member HDUs are expected, but
-not required, to contain a set of GRPIDn/GRPLCn keywords in their
-headers for each grouping table that they are referenced by. In this
-sense, the GRPIDn/GRPLCn keywords "link" the member HDU back to its
-Grouping table. Note that a member HDU need not reside in the same FITS
-file as its grouping table, and that a given HDU may be referenced by
-up to 999 grouping tables simultaneously.
-
-Grouping tables are implemented as FITS binary tables with up to six 
-pre-defined column TTYPEn values: 'MEMBER\_XTENSION', 'MEMBER\_NAME', 
-'MEMBER\_VERSION', 'MEMBER\_POSITION', 'MEMBER\_URI\_TYPE' and 'MEMBER\_LOCATION'. 
-The first three columns allow member HDUs to be identified by reference to
-their XTENSION, EXTNAME and EXTVER keyword values. The fourth column allows
-member HDUs to be identified by HDU position within their FITS file.
-The last two columns identify the FITS file in which the member HDU resides,
-if different from the grouping table FITS file.
-
-Additional user defined "auxiliary" columns may also be included with any 
-grouping table. When a grouping table is copied or modified the presence of 
-auxiliary columns is always taken into account by the grouping support 
-functions; however, the grouping support functions cannot directly
-make use of this data.
-
-If a grouping table column is defined but the corresponding member HDU 
-information is unavailable then a null value of the appropriate data type
-is inserted in the column field. Integer columns (MEMBER\_POSITION, 
-MEMBER\_VERSION) are defined with a TNULLn value of zero (0). Character field
-columns (MEMBER\_XTENSION, MEMBER\_NAME, MEMBER\_URI\_TYPE, MEMBER\_LOCATION) 
-utilize an ASCII null character to denote a null field value.
-
-The grouping support functions belong to two basic categories: those that
-work with grouping table HDUs (ffgt**) and those that work with member HDUs
-(ffgm**). Two functions, fits\_copy\_group() and fits\_remove\_group(), have the
-option to recursively copy/delete entire groups. Care should be taken when
-employing these functions in recursive mode as poorly defined groups could
-cause unpredictable results. The problem of a grouping table directly or 
-indirectly referencing itself (thus creating an infinite loop) is protected 
-against; in fact, neither function will attempt to copy or delete an HDU
-twice.
-
-**A.  Grouping Table Routines
-
->1 Create (append) a grouping table at the end of the current FITS file 
-   pointed to by fptr. The grpname parameter provides the grouping table
-   name (GRPNAME keyword value) and may be set to NULL if no group name
-   is to be specified. The grouptype parameter specifies the desired 
-   structure of the grouping table and may take on the values: 
-   GT\_ID\_ALL\_URI (all columns created), GT\_ID\_REF (ID by reference columns),
-   GT\_ID\_POS (ID by position columns), GT\_ID\_ALL (ID by reference and 
-   position columns), GT\_ID\_REF\_URI (ID by reference and FITS file URI 
->  columns), and GT\_ID\_POS\_URI (ID by position and FITS file URI columns). \label{ffgtcr}
--
-  int fits_create_group / ffgtcr 
-      (fitsfile *fptr, char *grpname, int grouptype, > int *status)
--
->2 Create (insert) a grouping table just after the CHDU of the current FITS 
-   file pointed to by fptr. All HDUs below the the insertion point will be
-   shifted downwards to make room for the new HDU. The grpname parameter 
-   provides the grouping table name (GRPNAME keyword value) and may be set to 
-   NULL if no group name is to be specified. The grouptype parameter specifies
-   the desired structure of the grouping table and may take on the values: 
-   GT\_ID\_ALL\_URI (all columns created), GT\_ID\_REF (ID by reference columns),
-   GT\_ID\_POS (ID by position columns), GT\_ID\_ALL (ID by reference and 
-   position columns), GT\_ID\_REF\_URI (ID by reference and FITS file URI 
->  columns), and GT\_ID\_POS\_URI (ID by position and FITS file URI columns) \label{ffgtis}.
--
-  int fits_insert_group / ffgtis 
-      (fitsfile *fptr, char *grpname, int grouptype, > int *status)
--
->3 Change the structure of an existing grouping table pointed to by
-   gfptr. The grouptype parameter (see fits\_create\_group() for valid
-   parameter values) specifies the new structure of the grouping table. This
-   function only adds or removes grouping table columns, it does not add
-   or delete group members (i.e., table rows). If the grouping table already
-   has the desired structure then no operations are performed and function   
-   simply returns with a (0) success status code. If the requested structure
-   change creates new grouping table columns, then the column values for all
-   existing members will be filled with the null values appropriate to the
->  column type. \label{ffgtch}
--
-  int fits_change_group / ffgtch 
-      (fitsfile *gfptr, int grouptype, > int *status)
--
->4 Remove the group defined by the grouping table pointed to by gfptr, and 
-   optionally all the group member HDUs. The rmopt parameter specifies the 
-   action to be taken for
-   all members of the group defined by the grouping table. Valid values are:
-   OPT\_RM\_GPT (delete only the grouping table) and OPT\_RM\_ALL (recursively
-   delete all HDUs that belong to the group). Any groups containing the 
-   grouping table gfptr as a member are updated, and if rmopt == OPT\_RM\_GPT 
-   all members have their GRPIDn and GRPLCn  keywords updated accordingly. 
-   If rmopt == OPT\_RM\_ALL, then other groups that contain the deleted members
->  of gfptr are updated to reflect the deletion accordingly. \label{ffgtrm}
--
-  int fits_remove_group / ffgtrm 
-      (fitsfile *gfptr, int rmopt, > int *status)
--
->5 Copy (append) the group defined by the grouping table pointed to by infptr,
-   and optionally all group member HDUs, to the FITS file pointed to by 
-   outfptr. The cpopt parameter specifies the action to be taken for all 
-   members of the group infptr. Valid values are: OPT\_GCP\_GPT (copy only 
-   the grouping table) and OPT\_GCP\_ALL (recursively copy ALL the HDUs that 
-   belong to the group defined by infptr). If the cpopt == OPT\_GCP\_GPT then 
-   the members of infptr have their GRPIDn and GRPLCn keywords updated to 
-   reflect the existence of the new grouping table outfptr, since they now 
-   belong to the new group. If cpopt == OPT\_GCP\_ALL then the new 
-   grouping table outfptr only contains pointers to the copied member HDUs
-   and not the original member HDUs of infptr. Note that, when 
-   cpopt == OPT\_GCP\_ALL, all members of the group defined by infptr will be
-   copied to a single FITS file pointed to by outfptr regardless of their 
->  file distribution in the original group.  \label{ffgtcp}
--
-  int fits_copy_group / ffgtcp 
-      (fitsfile *infptr, fitsfile *outfptr, int cpopt, > int *status)
--
->6  Merge the two groups defined by the grouping table HDUs infptr and outfptr
-    by combining their members into a single grouping table. All member HDUs
-    (rows) are copied from infptr to outfptr. If mgopt == OPT\_MRG\_COPY then
-    infptr continues to exist unaltered after the merge. If the mgopt ==
-    OPT\_MRG\_MOV then infptr is deleted after the merge. In both cases,
->   the GRPIDn and GRPLCn keywords of the member HDUs are updated accordingly. \label{ffgtmg}
--
-  int fits_merge_groups / ffgtmg 
-      (fitsfile *infptr, fitsfile *outfptr, int mgopt, > int *status)
--
->7 "Compact" the group defined by grouping table pointed to by gfptr. The 
-   compaction is achieved by merging (via fits\_merge\_groups()) all direct 
-   member HDUs of gfptr that are themselves grouping tables. The cmopt 
-   parameter defines whether the merged grouping table HDUs remain after 
-   merging (cmopt == OPT\_CMT\_MBR) or if they are deleted after merging 
-   (cmopt == OPT\_CMT\_MBR\_DEL). If the grouping table contains no direct
-   member HDUs that are themselves grouping tables then this function 
-   does nothing. Note that this function is not recursive, i.e., only the 
->  direct member HDUs of gfptr are considered for merging. \label{ffgtcm}
--
-  int fits_compact_group / ffgtcm 
-      (fitsfile *gfptr, int cmopt, > int *status)
--
->8 Verify the integrity of the grouping table pointed to by gfptr to make 
-   sure that all group members are accessible and that all links to other 
-   grouping tables are valid. The firstfailed parameter returns the member 
-   ID (row number) of the first member HDU to fail verification (if positive 
-   value) or the first group link to fail (if negative value). If gfptr is 
->  successfully verified then firstfailed contains a return value of 0. \label{ffgtvf}
--
-  int fits_verify_group / ffgtvf 
-      (fitsfile *gfptr, > long *firstfailed, int *status)
--
->9  Open a grouping table that contains the member HDU pointed to by mfptr. 
-    The grouping table to open is defined by the grpid parameter, which 
-    contains the keyword index value of the GRPIDn/GRPLCn keyword(s) that 
-    link the member HDU mfptr to the grouping table. If the grouping table 
-    resides in a file other than the member HDUs file then an attempt is 
-    first made to open the file readwrite, and failing that readonly. A 
-    pointer to the opened grouping table HDU is returned in gfptr.
- 
-    Note that it is possible, although unlikely and undesirable, for the 
-    GRPIDn/GRPLCn keywords in a member HDU header to be non-continuous, e.g., 
-    GRPID1, GRPID2, GRPID5, GRPID6. In such cases, the grpid index value 
-    specified in the function call shall identify the (grpid)th GRPID value. 
-    In the above example, if grpid == 3, then the group specified by GRPID5 
->   would be opened. \label{ffgtop}
--
-  int fits_open_group / ffgtop 
-      (fitsfile *mfptr, int group, > fitsfile **gfptr, int *status)
--
->10  Add a member HDU to an existing grouping table pointed to by gfptr.
-   The member HDU may either be pointed to mfptr (which must be positioned
-   to the member HDU) or, if mfptr == NULL, identified by the hdupos parameter 
-   (the HDU position number, Primary array == 1) if both the grouping table 
-   and the member HDU reside in the same FITS file. The new member HDU shall 
-   have the appropriate GRPIDn and GRPLCn keywords created in its header.
-   Note that if the member HDU is already a member of the group then it will 
->  not be added a second time. \label{ffgtam}

-  int fits_add_group_member / ffgtam 
-      (fitsfile *gfptr, fitsfile *mfptr, int hdupos, > int *status)
--
-
-**B.  Group Member Routines
-
->1  Return the number of member HDUs in a grouping table gfptr. The number
-    member HDUs is just the NAXIS2 value (number of rows) of the grouping 
->   table. \label{ffgtnm}
--
-  int fits_get_num_members / ffgtnm 
-      (fitsfile *gfptr, > long *nmembers, int *status)
--
->2   Return the number of groups to which the HDU pointed to by mfptr is 
-     linked, as defined by the number of GRPIDn/GRPLCn keyword records that 
-     appear in its header. Note that each time this function is called, the 
-     indices of the GRPIDn/GRPLCn keywords are checked to make sure they 
-     are continuous (ie no gaps) and are re-enumerated to eliminate gaps if 
->    found.  \label{ffgmng}
--
-  int fits_get_num_groups / ffgmng 
-      (fitsfile *mfptr, > long *nmembers, int *status)
--
->3  Open a member of the grouping table pointed to by gfptr. The member to 
-    open is identified by its row number within the grouping table as given
-    by the parameter 'member' (first member == 1) . A fitsfile pointer to 
-    the opened member HDU is returned as mfptr. Note that if the member HDU 
-    resides in a FITS file different from the grouping table HDU then the 
->   member file is first opened readwrite and, failing this, opened readonly. \label{ffgmop}
--
-  int fits_open_member / ffgmop 
-      (fitsfile *gfptr, long member, > fitsfile **mfptr, int *status)
--
->4 Copy (append) a member HDU of the grouping table pointed to by gfptr. 
-   The member HDU is identified by its row number within the grouping table 
-   as given by the parameter 'member' (first member == 1). The copy of the 
-   group member HDU will be appended to the FITS file pointed to by mfptr, 
-   and upon return mfptr shall point to the copied member HDU. The cpopt 
-   parameter may take on the following values: OPT\_MCP\_ADD which adds a new
-   entry in gfptr for the copied member HDU, OPT\_MCP\_NADD which does not add 
-   an entry in gfptr for the copied member, and OPT\_MCP\_REPL which replaces 
->  the original member entry with the copied member entry. \label{ffgmcp}

->5 Transfer a group member HDU from the grouping table pointed to by
-   infptr to the grouping table pointed to by outfptr. The member HDU to 
-   transfer is identified by its row number within infptr as specified by 
-   the parameter 'member' (first member == 1). If tfopt == OPT\_MCP\_ADD then 
-   the member HDU is made 
-   a member of outfptr and remains a member of infptr. If tfopt == OPT\_MCP\_MOV
->  then the member HDU is deleted from infptr after the transfer to outfptr. \label{ffgmtf}

->6 Remove a member HDU from the grouping table pointed to by gfptr. The 
-   member HDU to be deleted is identified by its row number in the grouping 
-   table as specified by the parameter 'member' (first member == 1). The rmopt 
-   parameter may take on the following values: OPT\_RM\_ENTRY which 
-   removes the member HDU entry from the grouping table and updates the

-*IX   Specialized CFITSIO Interface Routines
-
-The basic interface routines described previously are recommended
-for most uses, but the routines described in this chapter
-are also available if necessary.  Some of these routines perform more
-specialized function that cannot easily be done with the basic
-interface routines while others duplicate the functionality of the
-basic routines but have a slightly different calling sequence.
-See Appendix B for the definition of each function parameter.
-
-**A.  FITS File Access Routines
-
->1  Open an existing FITS file residing in core computer memory.  This
-routine is analogous to fits\_open\_file.   The 'filename'  is
-currently ignored by this routine and may be any arbitrary string. In
-general, the application must have preallocated an initial block of
-memory to hold the FITS file prior to calling this routine:  'memptr'
-points to the starting address and 'memsize' gives the initial size of
-the block of memory.  'mem\_realloc' is a pointer to an optional
-function that CFITSIO can call to allocate additional memory, if needed
-(only if mode = READWRITE), and is modeled after the standard C
-'realloc' function;  a null pointer may be given if the initial
-allocation of memory is all that will be required (e.g., if the file is
-opened with mode = READONLY).  The 'deltasize' parameter may be used to
-suggest a minimum amount of additional memory that should be allocated
-during each call to the memory reallocation function.  By default,
-CFITSIO will reallocate enough additional space to hold the entire
-currently defined FITS file (as given by the NAXISn keywords) or 1 FITS
-block (= 2880 bytes), which ever is larger.  Values of deltasize less
-than 2880 will be ignored.  Since the memory reallocation operation can
-be computationally expensive, allocating a larger initial block of
-memory, and/or specifying a larger deltasize value may help to reduce
-the number of reallocation calls and make the application program run
-faster.  Note that values of the memptr and memsize pointers will be updated
-by CFITSIO if the location or size of the FITS file in memory
->should change as a result of allocating more memory. \label{ffomem}

--
->2  Create a new FITS file residing in core computer memory.  This
-routine is analogous to fits\_create\_file.    In general, the
-application must have preallocated an initial block of memory to hold
-the FITS file prior to calling this routine:  'memptr' points to the
-starting address and 'memsize' gives the initial size of the block of
-memory.  'mem\_realloc' is a pointer to an optional function that

-allocating a larger initial block of memory, and/or specifying a larger
-deltasize value may help to reduce the number of reallocation calls
-and make the application program run

-by CFITSIO if the location or size of the FITS file in memory
->should change as a result of allocating more memory. \label{ffimem}

--
->3  Reopen a FITS file that was previously opened with 
-    fits\_open\_file or fits\_create\_file.  The new fitsfile
-    pointer may then be treated as a separate file, and one may
-    simultaneously read or write to 2 (or more)  different extensions in
-    the same file.   The fits\_open\_file routine (above) automatically
-    detects cases where a previously opened file is being opened again,
-    and then internally call fits\_reopen\_file, so programs should rarely
-    need to explicitly call this routine.

-      (fitsfile *openfptr, fitsfile **newfptr, > int *status)
--
-
->4   Create a new FITS file, using a template file to define its
-  initial size and structure.  The template may be another FITS HDU
-  or an ASCII template file.  If the input template file name pointer
-  is null, then this routine behaves the same as fits\_create\_file.
-  The currently supported format of the ASCII template file is described
-  under the fits\_parse\_template routine (in the general Utilities 
-  section)

-  int fits_create_template / fftplt

--
-
->5  Parse the input filename or URL into its component parts, namely:
-\begin{itemize}
-\item
-the file type (file://, ftp://, http://, etc),
-\item
-the base input file name, 
-\item
-the name of the output file that the input file is to be copied to prior
-to opening, 
-\item
-the HDU or extension specification, 
-\item
-the filtering specifier,
-\item
-the binning specifier, 
-\item
-the column specifier, 
-\item
-and the
-image pixel filtering specifier.
-\end{itemize}
-A null pointer (0) may be be specified for any of the output string arguments
-that are not needed.  Null strings will be returned for any components that are not 
-present in the input file name.  The calling routine must allocate sufficient 
-memory to hold the returned character strings.  Allocating the string lengths 
-equal to FLEN\_FILENAME is guaranteed to be safe.
-These routines are mainly for internal use
->by other CFITSIO routines. \label{ffiurl}

--
->6  Parse the input filename and return the HDU number that would be
-moved to if the file were opened with fits\_open\_file.  The returned
-HDU number begins with 1 for the primary array, so for example, if the
-input filename = `myfile.fits[2]' then hdunum = 3 will be returned.
-CFITSIO does not open the file to check if the extension actually
-exists if an extension number is specified. If an extension name is
-included in the file name specification (e.g.  `myfile.fits[EVENTS]'
-then this routine will have to open the FITS file and look for the
-position of the named extension, then close file again.  This is not
-possible if the file is being read from the stdin stream, and an error
-will be returned in this case.  If the filename does not specify an
-explicit extension (e.g. 'myfile.fits') then hdunum = -99 will be
-returned, which is functionally equivalent to hdunum = 1. This routine
-is mainly used for backward compatibility in the ftools software
-package and is not recommended for general use.  It is generally better
-and more efficient to first open the FITS file with fits\_open\_file,
-then use fits\_get\_hdu\_num to determine which HDU in the file has
-been opened, rather than calling fits\_parse\_input\_url followed by a
-call to fits\_open\_file.

-name includes the file type if specified, (e.g.  'ftp://' or 'http://')
-and the full path name, to the extent that it is specified in the input
-filename.  It does not include the HDU name or number, or any filtering
-specifications. The calling routine must allocate sufficient

-the 'exists' parameter will have 1 of the 4 following values:
--
-   2:  the file does not exist, but a compressed version does exist
-   1:  the disk file does exist
-   0:  neither the file nor a compressed version of the file exist

--
->9 Flush any internal buffers of data to the output FITS file. These 
-   routines rarely need to be called, but can be useful in cases where
-   other processes need to access the same FITS file in real time,
-   either on disk or in memory.  These routines also help to ensure
-   that if the application program subsequently aborts then the FITS
-   file will have been closed properly.  The first routine,
-   fits\_flush\_file is more rigorous and completely closes, then
-   reopens, the current HDU, before flushing the internal buffers, thus
-   ensuring that the output FITS file is identical to what would be
-   produced if the FITS was closed at that point (i.e., with a call to
-   fits\_close\_file).  The second routine, fits\_flush\_buffer simply
-   flushes the internal CFITSIO buffers of data to the output FITS
-   file, without updating and closing the current HDU.  This is much
-   faster, but there may be circumstances where the flushed file does
-   not completely reflect the final state of the file as it will exist
-   when the file is actually closed.
-
-   A typical use of these routines would be to flush the state of a
-   FITS table to disk after each row of the table is written.  It is
-   recommend that fits\_flush\_file be called after the first row is
-   written, then fits\_flush\_buffer may be called after each
-   subsequent row is written.  Note that this latter routine will not
-   automatically update the NAXIS2 keyword which records the number of
-   rows of data in the table, so this keyword must be explicitly
-   updated by the application program after each row is written.

-**B.  HDU Access Routines
-
->1  Get the byte offsets in the FITS file to the start of the header 
-    and the start and end of the data in the CHDU. The difference
-    between headstart and dataend equals the size of the CHDU.  If the

->3  Insert a new IMAGE extension immediately following the CHDU, or

-    following extensions in the file will be shifted down to make room
-    for the new extension.  If the CHDU is the last HDU in the file
-    then the new image extension will simply be appended to the end of
-    the file.   One can force a new primary array to be inserted at the
-    beginning of the FITS file by setting status = PREPEND\_PRIMARY prior
-    to calling the routine.  In this case the old primary array will be
-    converted to an IMAGE extension. The new extension (or primary
-    array) will become the CHDU.  Refer to Chapter 9 for a list of

->4  Insert a new ASCII or binary table extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for the
-    new extension.  If there are no other following extensions then the
-    new table extension will simply be appended to the end of the
-    file.   If the FITS file is currently empty then this routine will
-    create a dummy primary array before appending the table to it. The
-    new extension will become the CHDU.  The tunit and extname
-    parameters are optional and a null pointer may be given if they are
-    not defined.  When inserting an ASCII table with
-    fits\_insert\_atbl, a null pointer  may given for the *tbcol
-    parameter in which case each column of the table will be separated
-    by a single space character. Similarly, if the input value of
-    rowlen is  0, then CFITSIO will calculate the default rowlength
-    based on the tbcol and ttype values.  Under normal circumstances, 
-    the nrows
-    paramenter should have a value of 0; CFITSIO will automatically update
-    the number of rows as data is written to the table.  When inserting a binary table
-    with fits\_insert\_btbl, if there are following extensions in the
-    file and if the table contains variable length array columns then
-    pcount must specify the expected final size of the data heap,
->   otherwise pcount must = 0. \label{ffitab} \label{ffibin}

->5  Modify the size, dimensions, and/or data type of the current
-    primary array or image extension. If the new image, as specified
-    by the input arguments, is larger than the current existing image
-    in the FITS file then zero fill data will be inserted at the end
-    of the current image and any following extensions will be moved 
-    further back in the file.  Similarly, if the new image is
-    smaller than the current image then any following extensions
-    will be shifted up towards the beginning of the FITS file
-    and the image data will be truncated to the new size.

->6  Copy the data (and not the header) from the CHDU associated with infptr

-    previously in the output CHDU.  This low level routine is used by 
-    fits\_copy\_hdu, but it may also be useful in certain application programs
-    that want to copy the data from one FITS file to another but also
-    want to modify the header keywords. The required FITS header keywords

->8  This routine forces CFITSIO to rescan the current header keywords that
-    define the structure of the HDU (such as the NAXIS and BITPIX
-    keywords) so that it reinitializes the internal buffers that
-    describe the HDU structure.  This routine is useful for
-    reinitializing the structure of an HDU if any of the required
-    keywords (e.g., NAXISn) have been modified.  In practice it should

-***1.  Header Information Routines
-
->1  Reserve space in the CHU for MOREKEYS more header keywords.
-    This routine may be called to allocate space for additional keywords
-    at the time the header is created (prior to writing any data).
-    CFITSIO can dynamically add more space to the header when needed,
-    however it is more efficient to preallocate the required space
->   if the size is known in advance. \label{ffhdef}

->2  Return the number of keywords in the header (not counting the END
-    keyword) and the current position
-    in the header.  The position is the number of the keyword record that
-    will be read next (or one greater than the position of the last keyword
-    that was read). A value of 1 is returned if the pointer is

-
-***2.  Read and Write the Required Keywords
-
->1  Write the required extension header keywords into the CHU.
-  These routines are not required, and instead the appropriate
-  header may be constructed by writing each individual keyword in the
-  proper sequence.
-  
-  The simpler fits\_write\_imghdr routine is equivalent to calling
-  fits\_write\_grphdr with the default values of simple = TRUE, pcount
-  = 0, gcount = 1, and extend = TRUE.  The PCOUNT, GCOUNT and EXTEND
-  keywords are not required in the primary header and are only written
-  if pcount is not equal to zero, gcount is not equal to zero or one,
-  and if extend is TRUE, respectively.  When writing to an IMAGE
-  extension, the SIMPLE and EXTEND parameters are ignored.  It is
-  recommended that fits\_create\_image or fits\_create\_tbl be used
-  instead of these routines to write the
-  required header keywords. The general fits\_write\_exthdr routine
-  may be used to write the header of any conforming FITS

->2  Write the ASCII table header keywords into the CHU.  The optional
-    TUNITn and EXTNAME keywords are written only if the input pointers
-    are not null.  A null pointer may given for the
-    *tbcol parameter in which case a single space will be inserted

->3  Write the binary table header keywords into the CHU.   The optional
-   TUNITn and EXTNAME keywords are written only if the input pointers
-   are not null.  The pcount parameter, which specifies the
-   size of the variable length array heap, should initially = 0;
-   CFITSIO will automatically update the PCOUNT keyword value if any
-   variable length array data is written to the heap.  The TFORM keyword
-   value for variable length vector columns should have the form 'Pt(len)'
-   or '1Pt(len)' where `t' is the data type code letter (A,I,J,E,D, etc.)
-   and  `len' is an integer specifying the maximum length of the vectors
-   in that column (len must be greater than or equal to the longest
-   vector in the column).  If `len' is not specified when the table is
-   created (e.g., the input TFORMn value is just '1Pt') then CFITSIO will
-   scan the column when the table is first closed and will append the
-   maximum length to the TFORM keyword value.  Note that if the table
-   is subsequently modified to increase the maximum length of the vectors
-   then the modifying program is responsible for also updating the TFORM 
->  keyword value.  \label{ffphbn}

-***3.  Write Keyword Routines
-
-These routines simply append a new keyword to the header and do not
-check to see if a keyword with the same name already exists.  In
-general it is preferable to use the fits\_update\_key routine to ensure
-that the same keyword is not written more than once to the header.  See
-Appendix B for the definition of the parameters used in these
-routines.
-
-
->1   Write (append) a new keyword of the appropriate data type into the CHU.
-     A null pointer may be entered for the comment parameter, which
-     will cause the comment field of the keyword to be left blank.  The
-     flt, dbl, cmp, and dblcmp versions of this routine have the added
-     feature that if the 'decimals' parameter is negative, then the 'G'
-     display format rather then the 'E' format will be used when
-     constructing the keyword value, taking the absolute value of
-     'decimals' for the precision.  This will suppress trailing zeros,
-     and will use a fixed format rather than an exponential format,
->    depending on the magnitude of the value. \label{ffpkyx}

-      (fitsfile *fptr, char *keyname, DTYPE *numval, int decimals,
-      char *comment, > int *status)
--
->2  Write (append) a string valued keyword into the CHU which may be longer
-    than 68 characters in length.  This uses the Long String Keyword
-    convention that is described in the`Local FITS Conventions' section
-    in Chapter 4.  Since this uses a non-standard FITS convention to
-    encode the long keyword string, programs which use this routine
-    should also call the fits\_write\_key\_longwarn routine to add some
-    COMMENT keywords to warn users of the FITS file that this
-    convention is being used.  The fits\_write\_key\_longwarn routine
-    also writes a keyword called LONGSTRN to record the version of the
-    longstring convention that has been used, in case a new convention
-    is adopted at some point in the future.   If the LONGSTRN keyword
-    is already present in the header, then fits\_write\_key\_longwarn
-    will
->   simply return without doing anything. \label{ffpkls} \label{ffplsw}

-  int fits_write_key_longwarn / ffplsw
-      (fitsfile *fptr, > int *status)
--
->3  Write (append) a numbered sequence of keywords into the CHU.  The
-    starting index number (nstart) must be greater than 0. One may
-    append the same comment to every keyword (and eliminate the need
-    to have an array of identical comment strings, one for each keyword) by
-    including the ampersand character as the last non-blank character in the
-    (first) COMMENTS string parameter.  This same string
-    will then be used for the comment field in all the keywords.
-    One may also enter a null pointer for the comment parameter to
->   leave the comment field of the keyword blank. \label{ffpknx}

-       DTYPE *numval, int decimals, char **comment, > int *status)
--
->4 Copy an indexed keyword from one HDU to another, modifying
-    the index number of the keyword name in the process.  For example,
-    this routine could read the TLMIN3 keyword from the input HDU
-    (by giving keyroot = `TLMIN' and innum = 3) and write it to the
-    output HDU with the keyword name TLMIN4 (by setting outnum = 4).
-    If the input keyword does not exist, then this routine simply
->   returns without indicating an error. \label{ffcpky}

-      (fitsfile *infptr, fitsfile *outfptr, int innum, int outnum,
-       char *keyroot, > int *status)
--
->5 Write (append) a `triple precision' keyword into the CHU in F28.16 format.
-    The floating point keyword value is constructed by concatenating the
-    input integer value with the input double precision fraction value
-    (which must have a value between 0.0 and 1.0). The ffgkyt routine should
-    be used to read this keyword value, because the other keyword reading
->   routines will not preserve the full precision of the value. \label{ffpkyt}
--
-  int fits_write_key_triple / ffpkyt
-      (fitsfile *fptr, char *keyname, long intval, double frac,

--
-***4.  Insert Keyword Routines
-
-These insert routines are somewhat less efficient than the `update' or
-`write' keyword routines  because the following keywords in the header
-must be shifted down to make room for the inserted keyword.  See
-Appendix B for the definition of the parameters used in these
-routines.
-
->1  Insert a new keyword record into the CHU at the specified position
-    (i.e., immediately preceding the (keynum)th keyword in the header.)
->  \label{ffirec}
--
-  int fits_insert_record / ffirec
-      (fitsfile *fptr, int keynum, char *card, > int *status)
--
->2  Insert a new keyword into the CHU.  The new keyword is inserted
-    immediately following the last keyword that has been read from the
-    header.  The `longstr' version has the same functionality as the
-    `str' version except that it also supports the local long string
-    keyword convention for strings longer than 68 characters.  A null
-    pointer may be entered for the comment parameter which will cause
-    the comment field to be left blank.  The flt, dbl, cmp, and dblcmp
-    versions of this routine have the added
-     feature that if the 'decimals' parameter is negative, then the 'G'
-     display format rather then the 'E' format will be used when
-     constructing the keyword value, taking the absolute value of

-
-Wild card characters may be used when specifying the name of the
-keyword to be read.
-
->1  Read a keyword value (with the appropriate data type) and comment from
-    the CHU.  If a NULL comment pointer is given on input, then the comment
-    string will not be returned.  If the value of the keyword is not defined
-    (i.e., the value field is blank) then an error status = VALUE\_UNDEFINED
-    will be returned and the input value will not be changed (except that

-**D.  Define Data Scaling and Undefined Pixel Parameters
- 
-These routines set or modify the internal parameters used by CFITSIO
-to either scale the data or to represent undefined pixels.  Generally
-CFITSIO will scale the data according to the values of the BSCALE and
-BZERO (or TSCALn and TZEROn) keywords, however these routines may be
-used to override the keyword values.  This may be useful when one wants
-to read or write the raw unscaled values in the FITS file.  Similarly,
-CFITSIO generally uses the value of the BLANK or TNULLn keyword to
-signify an undefined pixel, but these routines may be used to override
-this value.  These routines do not create or modify the corresponding
-header keyword values.  See Appendix B for the definition of the
-parameters used in these routines.
- 
->1  Reset the scaling factors in the primary array or image extension; does
-    not change the BSCALE and BZERO keyword values and only affects the

-    data value = (the value given in the FITS array) * BSCALE + BZERO.

-**E.  Specialized FITS Primary Array or IMAGE Extension I/O Routines 
- 
-These routines read or write data values in the primary data array
-(i.e., the first HDU in the FITS file) or an IMAGE extension.
-Automatic data type conversion is performed for if the data type of the
-FITS array (as defined by the BITPIX keyword) differs from the data
-type of the array in the calling routine.  The data values are
-automatically scaled by the BSCALE and BZERO header values as they are
-being written or read from the FITS array.  Unlike the basic routines
-described in the previous chapter, most of these routines specifically
-support the FITS random groups format.  See Appendix B for the
-definition of the parameters used in these routines.
-
-The more primitive reading and writing routines (i. e., ffppr\_,
-ffppn\_, ffppn, ffgpv\_, or ffgpf\_) simply treat the primary array as
-a long 1-dimensional array of pixels, ignoring the intrinsic
-dimensionality of the array.  When dealing with a 2D image, for
-example, the application program must calculate the pixel offset in the
-1-D array that corresponds to any particular X, Y coordinate in the
-image.  C programmers should note that the ordering of arrays in FITS
-files, and hence in all the CFITSIO calls, is more similar to the
-dimensionality of arrays in Fortran rather than C.  For instance if a
-FITS image has NAXIS1 = 100 and NAXIS2 = 50, then a 2-D array just
-large enough to hold the image should be declared as array[50][100] and
-not as array[100][50].
-
-For convenience, higher-level routines are also provided to specifically
-deal with 2D images (ffp2d\_ and ffg2d\_) and 3D data cubes (ffp3d\_
-and ffg3d\_).  The dimensionality of the FITS image is passed by the
-naxis1, naxis2, and naxis3 parameters and the declared dimensions of
-the program array are passed in the dim1 and dim2 parameters.  Note
-that the dimensions of the program array may be larger than the
-dimensions of the FITS array.  For example if a FITS image with NAXIS1
-= NAXIS2 = 400 is read into a program array which is dimensioned as 512
-x 512 pixels, then the image will just fill the lower left corner of
-the array with pixels in the range 1 - 400 in the X an Y directions.
-This has the effect of taking a contiguous set of pixel value in the
-FITS array and writing them to a non-contiguous array in program memory
-(i.e., there are now some blank pixels around the edge of the image in
-the program array).
-
-The most general set of routines (ffpss\_, ffgsv\_, and ffgsf\_) may be
-used to transfer a rectangular subset of the pixels in a FITS
-N-dimensional image to or from an array which has been declared in the
-calling program.  The fpixel and lpixel parameters are integer arrays
-which specify the starting and ending pixel coordinate in each dimension
-(starting with 1, not 0) of the FITS image that is to be read or
-written.  It is important to note that these are the starting and
-ending pixels in the FITS image, not in the declared array in the
-program. The array parameter in these routines is treated simply as a
-large one-dimensional array of the appropriate data type containing the
-pixel values; The pixel values in the FITS array are read/written
-from/to this program array in strict sequence without any gaps;  it is
-up to the calling routine to correctly interpret the dimensionality of
-this array.  The two FITS reading routines (ffgsv\_ and ffgsf\_ ) also
-have an `inc' parameter which defines the data sampling interval in
-each dimension of the FITS array.  For example, if inc[0]=2 and
-inc[1]=3 when reading a 2-dimensional FITS image, then only every other
-pixel in the first dimension and every 3rd pixel in the second
-dimension will be returned to the 'array' parameter.
-
-Two types of routines are provided to read the data array which differ in
-the way undefined pixels are handled.  The first type of routines (e.g.,
-ffgpv\_) simply return an array of data elements in which undefined
-pixels are set equal to a value specified by the user in the `nulval'
-parameter.  An additional feature of these routines is that if the user
-sets nulval = 0, then no checks for undefined pixels will be performed,
-thus reducing the amount of CPU processing.  The second type of routines
-(e.g., ffgpf\_) returns the data element array and, in addition, a char
-array that indicates whether the value of the corresponding data pixel
-is undefined (= 1) or defined (= 0).  The latter type of routines may
-be more convenient to use in some circumstances, however, it requires
-an additional array of logical values which can be unwieldy when working
-with large data arrays.

-
->1  Get information about an existing ASCII or binary table column.   A null
-    pointer may be given for any of the output parameters that are not
-    needed.  DATATYPE is a character string which returns the data type
-    of the column as defined by the TFORMn keyword (e.g., 'I', 'J','E',
-    'D', etc.).  In the case of an ASCII character column, typecode
-    will have a value of the form 'An' where 'n' is an integer
-    expressing the width of the field in characters.  For example, if
-    TFORM = '160A8' then ffgbcl will return typechar='A8' and
-    repeat=20.   All the returned parameters are scalar quantities.

-    to start immediately following the regular table data, i.e., at
-    location NAXIS1 x NAXIS2.  This routine is only relevant for
-    binary tables which contain variable length array columns (with
-    TFORMn = 'Pt').  This routine also automatically writes

-    any unused space.  Normally, when a vector in a variable length
-    array column is rewritten the previously written array remains in
-    the heap as wasted unused space.  This routine will repack the
-    arrays that are still in use, thus eliminating any bytes in the
-    heap that are no longer in use.  Note that if several vectors point
-    to the same bytes in the heap, then this routine will make

-***2.  Low-Level Table Access Routines
- 
-The following 2 routines provide low-level access to the data in ASCII

-or part of a table from one location to another.  These routines simply
-read or write the specified number of consecutive bytes in an ASCII or
-binary table, without regard for column boundaries or the row length in
-the table.  These routines do not perform any machine dependent data
-conversion or byte swapping.  See Appendix B for the definition of the
-parameters used in these routines.

-***3.  Write Column Data Routines
-
->1  Write elements into an ASCII or binary table column (in the CDU).
-    The data type of the array is implied by the suffix of the
->   routine name. \label{ffpcls}

-  int fits_write_col_str / ffpcls

--
->2  Write elements into an ASCII or binary table column
-    substituting the appropriate FITS null value for any elements that
->    are equal to the nulval parameter.    \label{ffpcnx}
--
-  int fits_write_colnull_[log, byt, sht, usht, int, uint, lng, ulng, lnglng, flt, dbl] /
-      ffpcn[l,b,i,ui,k,uk,j,uj,jj,e,d]
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, LONGLONG firstelem,
-       LONGLONG nelements, DTYPE *array, DTYPE nulval, > int *status)
--
->3  Write string elements into a binary table column (in the CDU)
-    substituting the FITS null value for any elements that
->   are equal to the nulstr string.  \label{ffpcns}
--
-  int fits_write_colnull_str / ffpcns
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, LONGLONG firstelem,
-       LONGLONG nelements, char **array, char *nulstr, > int *status)
--
->4  Write bit values into a binary byte ('B') or bit ('X') table column (in
-    the CDU).  Larray is an array of characters corresponding to the
-    sequence of bits to be written.  If an element of larray is true
-    (not equal to zero) then the corresponding bit in the FITS table is
-    set to 1, otherwise the bit is set to 0.  The 'X' column in a FITS
-    table is always padded out to a multiple of 8 bits where the bit
-    array starts with the most significant bit of the byte and works
-    down towards the 1's bit.  For example, a '4X' array, with the
-    first bit = 1 and the remaining 3 bits = 0 is equivalent to the 8-bit
-    unsigned byte decimal value of 128  ('1000 0000B').  In the case of
-    'X' columns, CFITSIO can write to all 8 bits of each byte whether
-    they are formally valid or not.  Thus if the column is defined as
-    '4X', and one calls ffpclx with firstbit=1 and nbits=8, then all
-    8 bits will be written into the first byte (as opposed to writing
-    the first 4 bits into the first row and then the next 4 bits into
-    the next row), even though the last 4 bits of each byte are formally
-    not defined and should all be set = 0.  It should also be noted that
-    it is more efficient to write 'X' columns an entire byte at a time,
-    instead of bit by bit.  Any of the CFITSIO routines that write to
-    columns (e.g. fits\_write\_col\_byt) may be used for this purpose.
-    These routines will interpret 'X' columns as though they were 'B'
-    columns (e.g.,  '1X' through '8X' is equivalent
->   to '1B', and '9X' through '16X' is equivalent to '2B').  \label{ffpclx}
--
-  int fits_write_col_bit / ffpclx
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, long firstbit, 
-       long nbits, char *larray, > int *status)
--
->5  Write the descriptor for a variable length column in a binary table.
-    This routine can be used in conjunction with ffgdes to enable
-    2 or more arrays to point to the same storage location to save
->   storage space if the arrays are identical. \label{ffpdes}
--
-    int fits_write_descript / ffpdes
-        (fitsfile *fptr, int colnum, LONGLONG rownum, LONGLONG repeat,
-         LONGLONG offset, > int *status)
--
-***4.  Read Column Data Routines
-
-Two types of routines are provided to get the column data which differ
-in the way undefined pixels are handled.  The first set of routines
-(ffgcv) simply return an array of data elements in which undefined
-pixels are set equal to a value specified by the user in the 'nullval'
-parameter.  If nullval = 0, then no checks for undefined pixels will be
-performed, thus increasing the speed of the program.  The second set of
-routines (ffgcf) returns the data element array and in addition a
-logical array of flags which defines whether the corresponding data
-pixel is undefined.  See Appendix B for the definition of the
-parameters used in these routines.
-
-    Any column, regardless of it's intrinsic data type, may be read as a
-    string.  It should be noted however that reading a numeric column as
-    a string is 10 - 100 times slower than reading the same column as a number
-    due to the large overhead in constructing the formatted strings.
-    The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    data type of the column.  The length of the returned strings (not
-    including the null terminating character) can be determined with
-    the fits\_get\_col\_display\_width routine.  The following TDISPn
-    display formats are currently supported:
--
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
--
-    where w is the width in characters of the displayed values, m is
-    the minimum number of digits displayed, and d is the number of
-    digits to the right of the decimal.  The .m field is optional.
-
->1  Read elements from an ASCII or binary table column (in the CDU).  These
-    routines return the values of the table column array elements.  Undefined
-    array elements will be returned with a value = nulval, unless nulval = 0
-    (or = ' ' for ffgcvs) in which case no checking for undefined values will
-    be performed. The ANYF parameter is set to true if any of the returned
->   elements are undefined. \label{ffgcvx}

--
->2  Read elements and null flags from an ASCII or binary table column (in the
-    CHDU).  These routines return the values of the table column array elements.
-    Any undefined array elements will have the corresponding nullarray element
-    set equal to TRUE.  The anynul parameter is set to true if any of the
->   returned elements are undefined. \label{ffgcfx}

--
->3  Read an arbitrary data subsection from an N-dimensional array
-    in a binary table vector column.  Undefined pixels
-    in the array will be set equal to the value of 'nulval',
-    unless nulval=0 in which case no testing for undefined pixels will
-    be performed.  The first and last rows in the table to be read
-    are specified by fpixel(naxis+1) and lpixel(naxis+1), and hence
-    are treated as the next higher dimension of the FITS N-dimensional
-    array.  The INC parameter specifies the sampling interval in
->   each dimension between the data elements that will be returned. \label{ffgsvx2}

-      (fitsfile *fptr, int colnum, int naxis, long *naxes, long *fpixel,
-       long *lpixel, long *inc, DTYPE nulval, > DTYPE *array, int *anynul,
-       int *status)
--
->4  Read an arbitrary data subsection from an N-dimensional array
-    in a binary table vector column.  Any Undefined
-    pixels in the array will have the corresponding 'nullarray'
-    element set equal to TRUE.  The first and last rows in the table
-    to be read are specified by fpixel(naxis+1) and lpixel(naxis+1),
-    and hence are treated as the next higher dimension of the FITS
-    N-dimensional array.  The INC parameter specifies the sampling
-    interval in each dimension between the data elements that will be
->   returned. \label{ffgsfx2}

-      (fitsfile *fptr, int colnum, int naxis, long *naxes, 
-       long *fpixel, long *lpixel, long *inc, > DTYPE *array, 
-       char *nullarray, int *anynul, int *status)
--
->5  Read bit values from a byte ('B') or bit (`X`) table column (in the
-    CDU).  Larray is an array of logical values corresponding to the
-    sequence of bits to be read.  If larray is true then the
-    corresponding bit was set to 1, otherwise the bit was set to 0.
-    The 'X' column in a FITS table is always padded out to a multiple
-    of 8 bits where the bit array starts with the most significant bit
-    of the byte and works down towards the 1's bit.  For example, a
-    '4X' array, with the first bit = 1 and the remaining 3 bits = 0 is
-    equivalent to the 8-bit unsigned byte value of 128. 
-    Note that in the case of 'X' columns, CFITSIO can read  all 8 bits
-    of each byte whether they are formally valid or not.  Thus if the
-    column is defined as '4X', and one calls ffgcx with  firstbit=1 and
-    nbits=8, then all 8 bits will be read from the first byte (as
-    opposed to reading the first 4 bits from the first row and then the
-    first 4 bits from the next row), even though the last 4 bits of
-    each byte are formally not defined.  It should also be noted that
-    it is more efficient to read 'X' columns an entire byte at a time,
-    instead of bit by bit.  Any of the CFITSIO routines that read 
-    columns (e.g. fits\_read\_col\_byt) may be used for this
-    purpose.  These routines will interpret 'X' columns as though they
-    were 'B' columns (e.g.,  '8X' is equivalent to '1B', and '16X' is
->   equivalent to '2B').  \label{ffgcx}
--
-  int fits_read_col_bit / ffgcx
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, LONGLONG firstbit, 
-       LONGLONG nbits, > char *larray, int *status)
--
->6  Read any consecutive set of bits from an 'X' or 'B' column and
-    interpret them as an unsigned n-bit integer.  nbits must be less
-    than 16 or 32 in ffgcxui and ffgcxuk, respectively.  If nrows
-    is greater than 1, then the same set of bits will be read from
-    each row, starting with firstrow. The bits are numbered with
-    1 = the most significant bit of the first element of the column.

--
->7  Return the descriptor for a variable length column in a binary table.
-    The descriptor consists of 2 integer parameters: the number of elements
-    in the array and the starting offset relative to the start of the heap.
-    The first pair of routine returns a single descriptor whereas the second 
-    pair of routine
-    returns the descriptors for a range of rows in the table.  The only 
-    difference between the 2 routines in each pair is that one returns
-    the parameters as 'long' integers, whereas the other returns the values
-    as 64-bit 'LONGLONG' integers.

-*X.   Extended File Name Syntax
-
-**A.  Overview
-
-CFITSIO supports an extended syntax when specifying the name of the
-data file to be opened or created  that includes the following
-features:
-
-\begin{itemize}
-\item
-CFITSIO can read IRAF format images which have header file names that
-end with the '.imh' extension, as well as reading and writing FITS
-files,   This feature is implemented in CFITSIO by first converting the
-IRAF image into a temporary FITS format file in memory, then opening
-the FITS file.  Any of the usual CFITSIO routines then may be used to
-read the image header or data.  Similarly, raw binary data arrays can
-be read by converting them on the fly into virtual FITS images.
-
-\item
-FITS files on the Internet can be read (and sometimes written) using the FTP,
-HTTP, or ROOT protocols.
-
-\item
-FITS files can be piped between tasks on the stdin and stdout streams.
-
-\item
-FITS files can be read and written in shared memory.  This can
-potentially achieve better data I/O performance compared to reading and
-writing the same FITS files on magnetic disk.
-
-\item
-Compressed FITS files in gzip or Unix COMPRESS format can be directly read.
-
-\item
-Output FITS files can be written directly in compressed gzip format,
-thus saving disk space.
-
-\item
-FITS table columns can be created, modified, or deleted 'on-the-fly' as
-the table is opened by CFITSIO.  This creates a virtual FITS file containing
-the modifications that is then opened by the application program.
-
-\item
-Table rows may be selected, or filtered out, on the fly when the table
-is opened by CFITSIO, based on an user-specified expression.
-Only rows for which the expression evaluates to 'TRUE' are retained
-in the copy of the table that is opened by the application program.
-
-\item
-Histogram images may be created on the fly by binning the values in
-table columns, resulting in a virtual N-dimensional FITS image.  The
-application program then only sees the FITS image (in the primary
-array) instead of the original FITS table.
-\end{itemize}
-
-The latter 3 table filtering features in particular add very powerful
-data processing capabilities directly into CFITSIO, and hence into
-every task that uses CFITSIO to read or write FITS files.  For example,
-these features transform a very simple program that just copies an
-input FITS file to a new output file (like the `fitscopy' program that
-is distributed with CFITSIO) into a multipurpose FITS file processing
-tool.  By appending fairly simple qualifiers onto the name of the input
-FITS file, the user can perform quite complex table editing operations
-(e.g., create new columns, or filter out rows in a table) or create
-FITS images by binning or histogramming the values in table columns.
-In addition, these functions have been coded using new state-of-the art
-algorithms that are, in some cases, 10 - 100 times faster than previous
-widely used implementations.
-
-Before describing the complete syntax for the extended FITS file names
-in the next section, here are a few examples of FITS file names that
-give a quick overview of the allowed syntax:
-
-\begin{itemize}
-\item
-{\tt myfile.fits}: the simplest case of a FITS file on disk in the current
-directory.
-
-\item
-{\tt myfile.imh}: opens an IRAF format image file and converts it on the
-fly into a temporary FITS format image in memory which can then be read with
-any other CFITSIO routine.
-
-\item
-{\tt rawfile.dat[i512,512]}: opens a raw binary data array (a 512 x 512
-short integer array in this case) and converts it on the fly into a
-temporary FITS format image in memory which can then be read with any
-other CFITSIO routine.
-
-\item
-{\tt myfile.fits.gz}: if this is the name of a new output file, the '.gz'
-suffix will cause it to be compressed in gzip format when it is written to 
-disk.
-
-\item
-{\tt myfile.fits.gz[events, 2]}:  opens and uncompresses the gzipped file
-myfile.fits then moves to the extension with the keywords EXTNAME
-= 'EVENTS' and EXTVER = 2.
-
-\item
-{\tt -}:  a dash (minus sign) signifies that the input file is to be read
-from the stdin file stream, or that the output file is to be written to
-the stdout stream.  See also the stream:// driver which provides a 
-more efficient, but more restricted method of reading or writing to 
-the stdin or stdout streams. 
-
-\item
-{\tt ftp://legacy.gsfc.nasa.gov/test/vela.fits}:  FITS files in any ftp
-archive site on the Internet may be directly opened with read-only
-access.
-
-\item
-{\tt http://legacy.gsfc.nasa.gov/software/test.fits}: any valid URL to a
-FITS file on the Web may be opened with read-only access.
-
-\item
-{\tt root://legacy.gsfc.nasa.gov/test/vela.fits}: similar to ftp access
-except that it provides write as well as read access to the files
-across the network. This uses the root protocol developed at CERN.
-
-\item
-{\tt shmem://h2[events]}: opens the FITS file in a shared memory segment and
-moves to the EVENTS extension.  
-
-\item
-{\tt mem://}:  creates a scratch output file in core computer memory.  The
-resulting 'file' will disappear when the program exits, so this
-is mainly useful for testing purposes when one does not want a
-permanent copy of the output file.
-
-\item
-{\tt myfile.fits[3; Images(10)]}: opens a copy of the image contained in the
-10th row of the 'Images' column in the binary table in the 3th extension
-of the FITS file.  The virtual file that is opened by the application just
-contains this single image in the primary array.
-
-\item
-{\tt myfile.fits[1:512:2, 1:512:2]}: opens a section of the input image
-ranging from the 1st to the 512th pixel in  X and Y, and selects every 
-second pixel in both dimensions, resulting in a 256 x 256 pixel input image 
-in this case.
-
-\item
-{\tt myfile.fits[EVENTS][col Rad = sqrt(X**2 + Y**2)]}:  creates and opens
-a virtual file on the fly that is identical to
-myfile.fits except that it will contain a new column in the EVENTS
-extension called 'Rad' whose value is computed using the indicated
-expression which is a function of the values in the X and Y columns.
-
-\item
-{\tt myfile.fits[EVENTS][PHA > 5]}:  creates and opens a virtual FITS
-files that is identical to 'myfile.fits' except that the EVENTS table
-will only contain the rows that have values of the PHA column greater
-than 5.  In general, any arbitrary boolean expression using a C or
-Fortran-like syntax, which may combine AND and OR operators,
-may be used to select rows from a table.
-
-\item
-{\tt myfile.fits[EVENTS][bin (X,Y)=1,2048,4]}:  creates a temporary FITS
-primary array image which is computed on the fly by binning (i.e,
-computing the 2-dimensional histogram) of the values in the X and Y
-columns of the EVENTS extension.  In this case the X and Y coordinates
-range from 1 to 2048 and the image pixel size is 4 units in both
-dimensions, so the resulting image is 512 x 512 pixels in size.
-
-\item
-The final example combines many of these feature into one complex
-expression (it is broken into several lines for clarity):
--
-   ftp://legacy.gsfc.nasa.gov/data/sample.fits.gz[EVENTS]
-   [col phacorr = pha * 1.1 - 0.3][phacorr >= 5.0 && phacorr <= 14.0]
-   [bin (X,Y)=32] 
--
-In this case, CFITSIO (1) copies and uncompresses the FITS file from
-the ftp site on the legacy machine, (2) moves to the 'EVENTS'
-extension, (3) calculates a new column called 'phacorr', (4) selects
-the rows in the table that have phacorr in the range 5 to 14, and
-finally (5) bins the remaining rows on the X and Y column coordinates,
-using a pixel size = 32 to create a 2D image.  All this processing is
-completely transparent to the application program, which simply sees
-the final 2-D image in the primary array of the opened file.
-\end{itemize}
-
-The full extended CFITSIO FITS file name can contain several different
-components depending on the context.  These components are described in
-the following sections:
--
-When creating a new file:
-   filetype://BaseFilename(templateName)[compress]
-
-When opening an existing primary array or image HDU:
-   filetype://BaseFilename(outName)[HDUlocation][ImageSection][pixFilter]
-
-When opening an existing table HDU:
-   filetype://BaseFilename(outName)[HDUlocation][colFilter][rowFilter][binSpec]
--
-The filetype, BaseFilename, outName, HDUlocation, ImageSection, and pixFilter
-components, if present, must be given in that order, but the colFilter,
-rowFilter, and binSpec specifiers may follow in any order.  Regardless
-of the order, however, the colFilter specifier, if present, will be
-processed first by CFITSIO, followed by the rowFilter specifier, and
-finally by the binSpec specifier.
-
-**A.  Filetype
-
-The type of file determines the medium on which the file is located
-(e.g., disk or network) and, hence, which internal device driver is used by
-CFITSIO to read and/or write the file.  Currently supported types are
--
-        file://  - file on local magnetic disk (default)
-         ftp://  - a readonly file accessed with the anonymous FTP protocol.
-                   It also supports  ftp://username:password@hostname/...
-                   for accessing password-protected ftp sites.
-        http://  - a readonly file accessed with the HTTP protocol.  It
-                   supports username:password just like the ftp driver.
-                   Proxy HTTP servers are supported using the http_proxy
-                   environment variable (see following note).
-      stream://  - special driver to read an input FITS file from the stdin
-                   stream, and/or write an output FITS file to the stdout
-		   stream.  This driver is fragile and has limited
-		   functionality (see the following note).
-      gsiftp://  - access files on a computational grid using the gridftp
-                   protocol in the Globus toolkit (see following note).
-        root://  - uses the CERN root protocol for writing as well as
-                   reading files over the network (see following note).
-       shmem://  - opens or creates a file which persists in the computer's
-                   shared memory (see following note).
-         mem://  - opens a temporary file in core memory.  The file 
-                   disappears when the program exits so this is mainly
-                   useful for test purposes when a permanent output file
-                   is not desired.
--
-If the filetype is not specified, then type file:// is assumed.
-The double slashes '//' are optional and may be omitted in most cases.
-
-***1.  Notes about HTTP proxy servers
-
-A proxy HTTP server may be used by defining the address (URL) and port 
-number of the proxy server with the http\_proxy environment variable.
-For example
--
-    setenv http_proxy http://heasarc.gsfc.nasa.gov:3128
--
-will cause CFITSIO to use port 3128 on the heasarc proxy server whenever
-reading a FITS file with HTTP.
-
-***2.  Notes about the stream filetype driver
-
-The stream driver can be used to efficiently read a FITS file from the stdin
-file stream or write a FITS to the stdout file stream.  However, because these
-input and output streams must be accessed sequentially, the FITS file reading or
-writing application must also read and write the file sequentially, at least
-within the tolerances described below.  
-
-CFITSIO supports 2 different methods for accessing FITS files on the stdin and
-stdout streams.  The original method, which is invoked by specifying a dash
-character, "-", as the name of the file when opening or creating it, works by
-storing a complete copy of the entire FITS file in memory.  In this case, when
-reading from stdin, CFITSIO will copy the entire stream into memory before doing
-any processing of the file.  Similarly, when writing to stdout, CFITSIO will
-create a copy of the entire FITS file in memory, before finally flushing it out
-to  the stdout stream when the FITS file is closed.  Buffering the entire FITS
-file in this way allows the application to randomly access any part of the FITS
-file, in any order, but it also requires that the user have sufficient available
-memory (or virtual memory) to store the entire file, which may not be possible
-in the case of very large files.  
-
-The newer stream filetype provides a more memory-efficient method of accessing
-FITS files on the stdin or stdout streams.  Instead of storing a copy of the
-entire FITS file in memory, CFITSIO only uses a set of internal  buffer which by
-default can store  40 FITS blocks, or about  100K bytes of the FITS file.  The
-application program must process the FITS file sequentially from beginning to
-end, within this 100K buffer.  Generally speaking the application  program must
-conform to the following restrictions:
-
-\begin{itemize}
-\item
-The program must finish reading or writing the header keywords 
-before reading or writing any data in the HDU.
-\item
-The HDU can contain at most about 1400 header keywords.  This is the
-maximum that can fit in the nominal 40 FITS block buffer.  In principle,
-this limit could be increased by recompiling CFITSIO with a larger
-buffer limit, which is set by the NIOBUF parameter in fitsio2.h.
-\item
-The program must read or write the data in a sequential manner from the 
-beginning to the end of the HDU.  Note that CFITSIO's internal 
-100K buffer allows a little latitude in meeting this requirement.
-\item
-The program cannot move back to a previous HDU in the FITS file.
-\item
-Reading or writing of variable length array columns in binary tables is not
-supported on streams, because this requires moving back and forth between the
-fixed-length portion of the binary table and the following heap area where the
-arrays are actually stored.
-\item
-Reading or writing of tile-compressed images is not supported on streams, 
-because the images are internally stored using variable length arrays.
-\end{itemize}
-
-***3.  Notes about the gsiftp filetype
-
-DEPENDENCIES: Globus toolkit (2.4.3 or higher) (GT) should be installed.
-There are two different ways to install GT:
-
-1) goto the globus toolkit web page www.globus.org and follow the
-   download and compilation instructions;
-   
-2) goto the Virtual Data Toolkit web page http://vdt.cs.wisc.edu/
-   and follow the instructions (STRONGLY SUGGESTED);
-
-Once a globus client has been installed in your system with a specific flavour
-it is possible to compile and install the CFITSIO libraries.
-Specific configuration flags must be used:
-
-1)  --with-gsiftp[[=PATH]] Enable Globus Toolkit gsiftp protocol support
-    PATH=GLOBUS\_LOCATION i.e. the location of your globus installation
-
-2)  --with-gsiftp-flavour[[=PATH] defines the specific Globus flavour
-        ex. gcc32
-
-Both the flags must be used and it is mandatory to set  both the PATH and the
-flavour.
-
-USAGE: To access files on a gridftp server it is necessary to use a gsiftp prefix:
-
-example: gsiftp://remote\_server\_fqhn/directory/filename
-
-The gridftp driver uses a local buffer on a temporary file the file is located
-in the /tmp directory. If you have special permissions on /tmp or you do not have a /tmp
-directory, it is possible to force another location setting the GSIFTP\_TMPFILE environment
-variable (ex. export GSIFTP\_TMPFILE=/your/location/yourtmpfile).
-
-Grid FTP supports multi channel transfer. By default a single channel transmission is
-available. However, it is possible to modify this behavior setting the GSIFTP\_STREAMS
-environment variable (ex. export GSIFTP\_STREAMS=8).
-
-
-***4.  Notes about the root filetype
-
-The original rootd server can be obtained from: 
-\verb-ftp://root.cern.ch/root/rootd.tar.gz-
-but, for it to work correctly with CFITSIO one has to use a modified
-version which supports a command to return the length of the file. 
-This modified version is available in rootd subdirectory
-in the CFITSIO ftp area at
--
-      ftp://legacy.gsfc.nasa.gov/software/fitsio/c/root/rootd.tar.gz.  
--
-
-This small server is started either by inetd when a client requests a
-connection to a rootd server or by hand (i.e. from the command line).
-The rootd server works with the ROOT TNetFile class. It allows remote
-access to ROOT database files in either read or write mode. By default
-TNetFile assumes port 432 (which requires rootd to be started as root).
-To run rootd via inetd add the following line to /etc/services:
--                                                                          
-  rootd     432/tcp                                                    
--                                                                    
-and to /etc/inetd.conf, add the following line: 
--
-  rootd stream tcp nowait root /user/rdm/root/bin/rootd rootd -i       
--                                                                    
-Force inetd to reread its conf file with \verb+kill -HUP <pid inetd>+.    
-You can also start rootd by hand running directly under your private 
-account (no root system privileges needed). For example to start     
-rootd listening on port 5151 just type:   \verb+rootd -p 5151+  
-Notice that no \& is needed. Rootd will go into background by itself.       
--
-  Rootd arguments:                                                     
-    -i                says we were started by inetd                    
-    -p port#          specifies a different port to listen on          
-    -d level          level of debug info written to syslog            
-                      0 = no debug (default)                           
-                      1 = minimum                                      
-                      2 = medium                                       
-                      3 = maximum                                      
--
-Rootd can also be configured for anonymous usage (like anonymous ftp).
-To setup rootd to accept anonymous logins do the following (while being
-logged in as root):                                  
--
-   - Add the following line to /etc/passwd:                             
-                                                                     
-     rootd:*:71:72:Anonymous rootd:/var/spool/rootd:/bin/false          
-                                                                     
-     where you may modify the uid, gid (71, 72) and the home directory  
-     to suite your system.                                              
-                                                                     
-   - Add the following line to /etc/group:                              
-                                                                     
-     rootd:*:72:rootd                                                   
-                                                                     
-     where the gid must match the gid in /etc/passwd.                   
-                                                                     
-   - Create the directories:                                            
-                                                                     
-     mkdir /var/spool/rootd                                             
-     mkdir /var/spool/rootd/tmp                                         
-     chmod 777 /var/spool/rootd/tmp                                     
-                                                                     
-     Where /var/spool/rootd must match the rootd home directory as      
-     specified in the rootd /etc/passwd entry.                          
-                                                                     
-   - To make writeable directories for anonymous do, for example:       
-                                                                     
-     mkdir /var/spool/rootd/pub                                         
-     chown rootd:rootd /var/spool/rootd/pub                             
--
-That's all.  Several additional remarks:  you can login to an anonymous
-server either with the names "anonymous" or "rootd".  The password should
-be of type user@host.do.main. Only the @ is enforced for the time
-being.  In anonymous mode the top of the file tree is set to the rootd
-home directory, therefore only files below the home directory can be
-accessed.  Anonymous mode only works when the server is started via
-inetd.
-                                                        
-***5.  Notes about the shmem filetype:
-
-Shared memory files are currently supported on most Unix platforms,
-where the shared memory segments are managed by the operating system
-kernel and `live' independently of processes. They are not deleted (by
-default) when the process which created them terminates, although they
-will disappear if the system is rebooted.  Applications can create
-shared memory files in CFITSIO by calling:
--
-   fit_create_file(&fitsfileptr, "shmem://h2", &status);
--
-where the root `file' names are currently restricted to be 'h0', 'h1',
-'h2', 'h3', etc., up to a maximum number defined by the the value of
-SHARED\_MAXSEG (equal to 16 by default).  This is a prototype
-implementation of the shared memory interface and a more robust
-interface, which will have fewer restrictions on the number of files
-and on their names, may be developed in the future.
-
-When opening an already existing FITS file in shared memory one calls
-the usual CFITSIO routine:
--
-   fits_open_file(&fitsfileptr, "shmem://h7", mode, &status)
--
-The file mode can be READWRITE or READONLY just as with disk files.
-More than one process can operate on READONLY mode files at the same
-time.  CFITSIO supports proper file locking (both in READONLY and
-READWRITE modes), so calls to fits\_open\_file may be locked out until
-another other process closes the file.
-
-When an application is finished accessing a FITS file in a shared
-memory segment, it may close it  (and the file will remain in the
-system) with fits\_close\_file, or delete it with fits\_delete\_file.
-Physical deletion is postponed until the last process calls
-ffclos/ffdelt.  fits\_delete\_file tries to obtain a READWRITE lock on
-the file to be deleted, thus it can be blocked if the object was not
-opened in READWRITE mode.
-
-A shared memory management utility program called `smem', is included
-with the CFITSIO distribution.  It can be built by typing `make smem';
-then type `smem -h' to get a list of valid options.  Executing smem
-without any options causes it to list all the shared memory segments
-currently residing in the system and managed by the shared memory
-driver. To get a list of all the shared memory objects, run the system
-utility program `ipcs  [-a]'.
-
-**B.  Base Filename
-
-The base filename is the name of the file optionally including the
-director/subdirectory path, and in the case of `ftp', `http', and `root'
-filetypes, the machine identifier.  Examples:
--
-    myfile.fits
-    !data.fits
-    /data/myfile.fits
-    fits.gsfc.nasa.gov/ftp/sampledata/myfile.fits.gz
--
-
-When creating a new output file on magnetic disk (of type file://) if
-the base filename begins with an exclamation point (!) then any
-existing file with that same basename will be deleted prior to creating
-the new FITS file.  Otherwise if the file to be created already exists,
-then CFITSIO will return an error and will not overwrite the existing
-file.  Note  that the exclamation point,  '!', is a special UNIX
-character, so if it is used  on the command line rather than entered at
-a task prompt, it must be  preceded by a backslash to force the UNIX
-shell to pass it verbatim to the application program.
-
-If the output disk file name ends with the suffix '.gz', then CFITSIO
-will compress the file using the gzip compression algorithm before
-writing it to disk.  This can reduce the amount of disk space used by
-the file.  Note that this feature requires that the uncompressed file
-be constructed in memory before it is compressed and written to disk,
-so it can fail if there is insufficient available memory.
-
-An input FITS file may be compressed with the gzip or Unix compress
-algorithms, in which case CFITSIO will uncompress the file on the fly
-into a temporary file (in memory or on disk).  Compressed files may
-only be opened with read-only permission.  When specifying the name of
-a compressed FITS file it is not necessary to append the file suffix
-(e.g., `.gz' or `.Z').  If CFITSIO cannot find the input file name
-without the suffix, then it will automatically search for a compressed
-file with the same root name.  In the case of reading ftp and http type
-files, CFITSIO generally looks for a compressed version of the file
-first, before trying to open the uncompressed file.  By default,
-CFITSIO copies (and uncompressed if necessary) the ftp or http FITS
-file into memory on the local machine before opening it.  This will
-fail if the local machine does not have enough memory to hold the whole
-FITS file, so in this case, the output filename specifier (see the next
-section) can be used to further control how CFITSIO reads ftp and http
-files.
-
-If the input file is an IRAF image file (*.imh file) then CFITSIO will
-automatically convert it on the fly into a virtual FITS image before it
-is opened by the application program.  IRAF images can only be opened
-with READONLY file access.
-
-Similarly, if the input file is a raw binary data array, then CFITSIO
-will convert it on the fly into a virtual FITS image with the basic set
-of required header keywords before it is opened by the application
-program (with READONLY access).  In this case the data type and
-dimensions of the image must be specified in square brackets following
-the filename (e.g. rawfile.dat[ib512,512]). The first character (case
-insensitive) defines the data type of the array:
--
-     b         8-bit unsigned byte
-     i        16-bit signed integer
-     u        16-bit unsigned integer
-     j        32-bit signed integer
-     r or f   32-bit floating point
-     d        64-bit floating point
--
-An optional second character specifies the byte order of the array
-values: b or B indicates big endian (as in FITS files and the native
-format of SUN UNIX workstations and Mac PCs) and l or L indicates
-little endian (native format of DEC OSF workstations and IBM PCs).  If
-this character is omitted then the array is assumed to have the native
-byte order of the local machine.  These data type characters are then
-followed by a series of one or more integer values separated by commas
-which define the size of each dimension of the raw array.  Arrays with
-up to 5 dimensions are currently supported.  Finally, a byte offset to
-the position of the first pixel in the data file may be specified by
-separating it with a ':' from the last dimension value.  If omitted, it
-is assumed that the offset = 0.  This parameter may be used to skip
-over any header information in the file that precedes the binary data.
-Further examples:
--
-  raw.dat[b10000]           1-dimensional 10000 pixel byte array
-  raw.dat[rb400,400,12]     3-dimensional floating point big-endian array
-  img.fits[ib512,512:2880]  reads the 512 x 512 short integer array in 
-                            a FITS file, skipping over the 2880 byte header
--
-
-One special case of input file is where the filename = `-' (a dash or
-minus sign) or 'stdin' or 'stdout', which signifies that the input file
-is to be read from the stdin stream, or written to the stdout stream if
-a new output file is being created.  In the case of reading from stdin,
-CFITSIO first copies the whole stream into a temporary FITS file (in
-memory or on disk), and subsequent reading of the FITS file occurs in
-this copy.  When writing to stdout, CFITSIO first constructs the whole
-file in memory (since random access is required), then flushes it out
-to the stdout stream when the file is closed.  In addition, if the
-output filename = '-.gz' or 'stdout.gz' then it will be gzip compressed
-before being written to stdout.
-
-This ability to read and write on the stdin and stdout steams allows
-FITS files to be piped between tasks in memory rather than having to
-create temporary intermediate FITS files on disk.  For example if task1
-creates an output FITS file, and task2 reads an input FITS file, the
-FITS file may be piped between the 2 tasks by specifying
--
-   task1 - | task2 - 
--
-where the vertical bar is the Unix piping symbol.  This assumes that the 2
-tasks read the name of the FITS file off of the command line.
-
-**C.  Output File Name when Opening an Existing File
-
-An optional output filename may be specified in parentheses immediately
-following the base file name to be opened.  This is mainly useful in
-those cases where CFITSIO creates a temporary copy of the input FITS
-file before it is opened and passed to the application program.  This
-happens by default when opening a network FTP or HTTP-type file, when
-reading a compressed FITS file on a local disk, when reading from the
-stdin stream, or when a column filter, row filter, or binning specifier
-is included as part of the input file specification.  By default this
-temporary file is created in memory.  If there is not enough memory to
-create the file copy, then CFITSIO will exit with an error.   In these
-cases one can force a permanent file to be created on disk, instead of
-a temporary file in memory, by supplying the name in parentheses
-immediately following the base file name.  The output filename can
-include the '!' clobber flag.
-
-Thus, if the input filename to CFITSIO is: 
-\verb+file1.fits.gz(file2.fits)+
-then CFITSIO will uncompress `file1.fits.gz' into the local disk file
-`file2.fits' before opening it.  CFITSIO does not automatically delete
-the output file, so it will still exist after the application program
-exits.
-
-The output filename "mem://" is also allowed, which will write the 
-output file into memory, and also allow write access to the file.  This
-'file' will disappear when it is closed, but this may be useful for
-some applications which only need to modify a temporary copy of the file.
-
-In some cases, several different temporary FITS files will be created
-in sequence, for instance, if one opens a remote file using FTP, then
-filters rows in a binary table extension, then create an image by
-binning a pair of columns.  In this case, the remote file will be
-copied to a temporary local file, then a second temporary file will be
-created containing the filtered rows of the table, and finally a third
-temporary file containing the binned image will be created.  In cases
-like this where multiple files are created, the outfile specifier will
-be interpreted the name of the final file as described below, in descending
-priority:
-
-\begin{itemize}
-\item
-as the name of the final image file if an image within a single binary
-table cell is opened or if an image is created by binning a table column.
-\item
-as the name of the file containing the filtered table if a column filter
-and/or a row filter are specified.
-\item
-as the name of the local copy of the remote FTP or HTTP file.
-\item
-as the name of the uncompressed version of the FITS file, if a
-compressed FITS file on local disk has been opened.
-\item
-otherwise, the output filename is ignored.
-\end{itemize}
-
-The output file specifier is useful when reading FTP or HTTP-type
-FITS files since it can be used to create a local disk copy of the file
-that can be reused in the future.  If the output file name = `*' then a
-local file with the same name as the network file will be created.
-Note that CFITSIO will behave differently depending on whether the
-remote file is compressed or not as shown by the following examples:
-\begin{itemize}
-\item
-\verb+ftp://remote.machine/tmp/myfile.fits.gz(*)+ - the remote compressed
-file is copied to the local compressed file `myfile.fits.gz', which
-is then uncompressed in local memory before being opened and passed
-to the application program.
-
-\item
-\verb+ftp://remote.machine/tmp/myfile.fits.gz(myfile.fits)+ - the
-remote compressed file is copied and uncompressed into the local file
-`myfile.fits'.  This example requires less local memory than the
-previous example since the file is uncompressed on disk instead of in
-memory.
-
-\item
-\verb+ftp://remote.machine/tmp/myfile.fits(myfile.fits.gz)+ - this will
-usually produce an error since CFITSIO itself cannot compress files.
-\end{itemize}
-
-The exact behavior of CFITSIO in the latter case depends on the type of
-ftp server running on the remote machine and how it is configured.  In
-some cases, if the file `myfile.fits.gz' exists on the remote machine,
-then the server will copy it to the local machine.  In other cases the
-ftp server will automatically create and transmit a compressed version
-of the file if only the uncompressed version exists.  This can get
-rather confusing, so users should use a certain amount of caution when
-using the output file specifier with FTP or HTTP file types, to make
-sure they get the behavior that they expect.
-
-**D.  Template File Name when Creating a New File
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described in the following Template Files chapter.
-
-**E.  Image Tile-Compression Specification
-
-When specifying the name of the output FITS file to be created, the
-user can indicate that images should be written in tile-compressed
-format (see section 5.5, ``Primary Array or IMAGE Extension I/O
-Routines'') by enclosing the compression parameters in square brackets
-following the root disk file name.  Here are some examples of the
-syntax for specifying tile-compressed output images:
--
-    myfile.fit[compress]    - use Rice algorithm and default tile size
-
-    myfile.fit[compress GZIP] - use the specified compression algorithm;
-    myfile.fit[compress Rice]     only the first letter of the algorithm 
-    myfile.fit[compress PLIO]     name is required.
-
-    myfile.fit[compress Rice 100,100]   - use 100 x 100 pixel tile size
-    myfile.fit[compress Rice 100,100;2] - as above, and use noisebits = 2
--
-
-**F.  HDU Location Specification
-
-The optional HDU location specifier defines which HDU (Header-Data
-Unit, also known as an `extension') within the FITS file to initially
-open.  It must immediately follow the base file name (or the output
-file name if present).  If it is not specified then the first HDU (the
-primary array) is opened.  The HDU location specifier is required if
-the colFilter, rowFilter, or binSpec specifiers are present, because
-the primary array is not a valid HDU for these operations. The HDU may
-be specified either by absolute position number, starting with 0 for
-the primary array, or by reference to the HDU name, and optionally, the
-version number and the HDU type of the desired extension.  The location
-of an image within a single cell of a binary table may also be 
-specified, as described below.
-
-The absolute position of the extension is specified either by enclosed
-the number in square brackets (e.g., `[1]' = the first extension
-following the primary array) or by preceded the number with a plus sign
-(`+1').  To specify the HDU by name, give the name of the desired HDU
-(the value of the EXTNAME or HDUNAME keyword) and optionally the
-extension version number (value of the EXTVER keyword) and the
-extension type (value of the XTENSION keyword: IMAGE, ASCII or TABLE,
-or BINTABLE), separated by commas and all enclosed in square brackets.
-If the value of EXTVER and XTENSION are not specified, then the first
-extension with the correct value of EXTNAME is opened. The extension
-name and type are not case sensitive, and the extension type may be
-abbreviated to a single letter (e.g., I = IMAGE extension or primary
-array, A or T = ASCII table extension, and B = binary table BINTABLE
-extension).   If the HDU location specifier is equal to `[PRIMARY]' or
-`[P]', then the primary array (the first HDU) will be opened.
-
-An optional pound sign character ("\#") may be appended to the extension
-name or number to signify that any other extensions in the file should
-be ignored during any subsequent file filtering operations.  For example,
-when doing row filtering operations on a table extension, CFITSIO normally
-creates a copy of the filtered table in memory, along with a verbatim
-copy of all the other extensions in the input FITS file.  If the pound
-sign is appended to the table extension name, then only that extension,
-and none of the other extensions in the file, will by copied to memory,
-as in the following example:
--
-   myfile.fit[events#][TIME > 10000]
--
-
-FITS images are most commonly stored in the primary array or an image
-extension, but images can also be stored as a vector in a single cell
-of a binary table (i.e. each row of the vector column contains a
-different image).  Such an image can be opened with CFITSIO by
-specifying the desired column  name and the row number after the binary
-table HDU specifier as shown in the following examples. The column name
-is separated from the HDU specifier by a semicolon and the row number
-is enclosed in parentheses.  In this case CFITSIO copies the image from
-the table cell into a temporary primary array before it is opened.  The
-application program then just sees the image in the primary array,
-without any extensions.  The particular row to be opened may be
-specified either by giving an absolute integer row number (starting
-with 1 for the first row), or by specifying a boolean expression that
-evaluates to TRUE for the desired row.  The first row that satisfies
-the expression will be used.  The row selection expression has the same
-syntax as described in the Row Filter Specifier section, below.
-
- Examples:
--
-   myfile.fits[3] - open the 3rd HDU following the primary array
-   myfile.fits+3  - same as above, but using the FTOOLS-style notation  
-   myfile.fits[EVENTS] - open the extension that has EXTNAME = 'EVENTS'
-   myfile.fits[EVENTS, 2]  - same as above, but also requires EXTVER = 2
-   myfile.fits[events,2,b] - same, but also requires XTENSION = 'BINTABLE'
-   myfile.fits[3; images(17)] - opens the image in row 17 of the 'images'
-                                column in the 3rd extension of the file.
-   myfile.fits[3; images(exposure > 100)] - as above, but opens the image
-                   in the first row that has an 'exposure' column value
-                   greater than 100.
--
-
-**G.  Image Section
-
-A virtual file containing a rectangular subsection of an image can be
-extracted and opened by specifying the range of pixels (start:end)
-along each axis to be extracted from the original image.  One can also
-specify an optional pixel increment (start:end:step) for each axis of
-the input image.  A pixel step = 1 will be assumed if it is not
-specified.  If the start pixel is larger then the end pixel, then the
-image will be flipped (producing a mirror image) along that dimension.
-An asterisk, '*', may be used to specify the entire range of an axis,
-and '-*' will flip the entire axis. The input image can be in the
-primary array, in an image extension, or contained in a vector cell of
-a binary table. In the later 2 cases the extension name or number must
-be specified before the image section specifier.
-
- Examples:
--
-  myfile.fits[1:512:2, 2:512:2] -  open a 256x256 pixel image
-              consisting of the odd numbered columns (1st axis) and 
-              the even numbered rows (2nd axis) of the image in the 
-              primary array of the file.
-
-  myfile.fits[*, 512:256] - open an image consisting of all the columns
-              in the input image, but only rows 256 through 512.  
-              The image will be flipped along the 2nd axis since
-              the starting pixel is greater than the ending pixel.
-
-  myfile.fits[*:2, 512:256:2] - same as above but keeping only
-              every other row and column in the input image.
-
-  myfile.fits[-*, *] - copy the entire image, flipping it along
-              the first axis.
-
-  myfile.fits[3][1:256,1:256] - opens a subsection of the image that
-              is in the 3rd extension of the file.
-
-  myfile.fits[4; images(12)][1:10,1:10] - open an image consisting
-	      of the first 10 pixels in both dimensions. The original
-	      image resides in the 12th row of the 'images' vector
-	      column in the table in the 4th extension of the file.
--
-
-When CFITSIO opens an image section it first creates a temporary file
-containing the image section plus a copy of any other HDUs in the
-file. (If a `\#' character is appended to the name or number of the 
-image HDU, as in  "myfile.fits[1\#][1:200,1:200]", then the other
-HDUs in the input file will not be copied into memory). 
-This temporary file is then opened by the application program,
-so it is not possible to write to or modify the input file when
-specifying an image section.  Note that CFITSIO automatically updates
-the world coordinate system keywords in the header of the image
-section, if they exist, so that the coordinate associated with each
-pixel in the image section will be computed correctly.
-
-**H.  Image Transform Filters
-
-CFITSIO can apply a user-specified mathematical function to the value
-of every pixel in a FITS image, thus creating a new virtual image
-in computer memory that is then opened and read by the application
-program.  The original FITS image is not modified by this process.
-
-The image transformation specifier is appended to the input
-FITS file name and is enclosed in square brackets.  It begins with the 
-letters 'PIX' to distinguish it from other types of FITS file filters
-that are recognized by CFITSIO.  The image transforming function may
-use any of the mathematical operators listed in the following 
-'Row Filtering Specification' section of this document.
-Some examples of  image transform filters are:
--
- [pix X * 2.0]               - multiply each pixel by 2.0
- [pix sqrt(X)]               - take the square root of each pixel
- [pix X + #ZEROPT            - add the value of the ZEROPT keyword
- [pix X>0 ? log10(X) : -99.] - if the pixel value is greater
-                               than 0, compute the base 10 log,
-                               else set the pixel = -99.
--
-Use the letter 'X' in the expression to represent the current pixel value
-in the image.  The expression is evaluated
-independently for each pixel in the image and may be a function of 1) the
-original pixel value, 2) the value of other pixels in the image at
-a given relative offset from the position of the pixel that is being
-evaluated, and 3) the value of 
-any header keywords.  Header keyword values are represented
-by the name of the keyword preceded by the '\#' sign.
-
-
-To access the the value of adjacent pixels in the image, 
-specify the (1-D) offset from the current pixel in curly brackets.  
-For example
--
- [pix  (x{-1} + x + x{+1}) / 3] 
--
-will replace each pixel value with the running mean of the values of that
-pixel and it's 2 neighboring pixels.  Note that in this notation the image
-is treated as a 1-D array, where each row of the image (or higher dimensional
-cube) is appended one after another in one long array of pixels.  
-It is possible to refer to pixels
-in the rows above or below the current pixel by using the value of the
-NAXIS1 header keyword.  For example
--
- [pix (x{-#NAXIS1} + x + x{#NAXIS1}) / 3]
--
-will compute the mean of each image pixel and the pixels immediately
-above and below it in the adjacent rows of the image.  
-The following more complex example
-creates a smoothed virtual image where each pixel 
-is a 3 x 3 boxcar average of the input image pixels: 
--
-  [pix (X + X{-1} + X{+1} 
-      + X{-#NAXIS1} + X{-#NAXIS1 - 1} + X{-#NAXIS1 + 1}
-      + X{#NAXIS1} + X{#NAXIS1 - 1} + X{#NAXIS1 + 1}) / 9.]
--
-If the pixel offset
-extends beyond the first or last pixel in the image, the function will
-evaluate to undefined, or NULL.
-
-For  complex  or commonly used image filtering operations,  
-one  can  write the expression into an external text  file and 
-then import it  into the  
-filter using  the syntax '[pix @filename.txt]'.   The mathematical
-expression can
-extend over multiple lines of text in the  file.   
-Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-By default, the datatype of the resulting image will be the same as
-the original image, but one may force a different datatype by appended
-a code letter to the 'pix' keyword:
--
-      pixb  -  8-bit byte    image with BITPIX =   8
-      pixi  - 16-bit integer image with BITPIX =  16
-      pixj  - 32-bit integer image with BITPIX =  32
-      pixr  - 32-bit float   image with BITPIX = -32
-      pixd  - 64-bit float   image with BITPIX = -64
--
-Also by default, any other HDUs in the input file will be copied without
-change to the 
-output virtual FITS file, but one may discard the other HDUs by adding 
-the number '1' to the 'pix' keyword (and following any optional datatype code
-letter).  For example:
--
-     myfile.fits[3][pixr1  sqrt(X)]
-- 
-will create a virtual FITS file containing only a primary array image
-with 32-bit floating point pixels that have a value equal to the square 
-root of the pixels in the image that is in the 3rd extension 
-of the 'myfile.fits' file.
-
-
-**I.  Column and Keyword Filtering Specification
-
-The optional column/keyword filtering specifier is used to modify the
-column structure and/or the header keywords in the HDU that was
-selected with the previous HDU location specifier. This filtering
-specifier must be enclosed in square brackets and can be distinguished
-from a general row filter specifier (described below) by the fact that
-it begins with the string 'col ' and is not immediately followed by an
-equals sign.  The original file is not changed by this filtering
-operation, and instead the modifications are made on a copy of the
-input FITS file (usually in memory), which also contains a copy of all
-the other HDUs in the file.  (If a `\#' character is appended to the name 
-or number of the 
-table HDU then only the primary array, and none of the other
-HDUs in the input file will be copied into memory).
-This temporary file is passed to the
-application program and will persist only until the file is closed or
-until the program exits, unless the outfile specifier (see above) is
-also supplied.
-
-The column/keyword filter can be used to perform the following
-operations.  More than one operation may be specified by separating
-them with commas or semi-colons.
-
-\begin{itemize}
-
-\item
-Copy only a specified list of columns columns to the filtered input file.
-The list of column name should be separated by semi-colons.  Wild card
-characters may be used in the column names to match multiple columns.
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table 
-except the explicitly deleted columns will appear in the filtered
-table (i.e., there is no need to explicitly list the columns to
-be included if any columns are being deleted).
-
-\item
-Delete a column or keyword by listing the name preceded by a minus sign
-or an exclamation mark (!), e.g., '-TIME' will delete the TIME column
-if it exists, otherwise the TIME keyword.  An error is returned if
-neither a column nor keyword with this name exists.  Note  that the
-exclamation point,  '!', is a special UNIX character, so if it is used
-on the command line rather than entered at a task prompt, it must be
-preceded by a backslash to force the UNIX shell to ignore it.
-
-\item
-Rename an existing column or keyword with the syntax 'NewName ==
-OldName'.  An error is returned if neither a column nor keyword with
-this name exists.
-
-\item
-Append a new column or keyword to the table.  To create a column,
-give the new name, optionally followed by the data type in parentheses,
-followed by a single equals sign and an  expression to be used to
-compute the value (e.g., 'newcol(1J) = 0' will create a new 32-bit
-integer column called 'newcol' filled with zeros).  The data type is
-specified using the same syntax that is allowed for the value of the
-FITS TFORMn keyword (e.g., 'I', 'J', 'E', 'D', etc. for binary tables,
-and 'I8', F12.3', 'E20.12', etc. for ASCII tables).  If the data type is
-not specified then an appropriate data type will be chosen depending on
-the form of the expression (may be a character string, logical, bit, long
-integer, or double column). An appropriate vector count (in the case
-of binary tables) will also be added if not explicitly specified.
-
-When creating a new keyword, the keyword name must be preceded by a 
-pound sign '\#', and the expression must evaluate to a scalar
-(i.e., cannot have a column name in the expression).  The comment
-string for the keyword may be specified in parentheses immediately
-following the keyword name (instead of supplying a data type as in
-the case of creating a new column).  If the keyword name ends with a
-pound sign '\#', then cfitsio will substitute the number of the 
-most recently referenced column for the \# character .  
-This is especially useful when writing
-a column-related keyword like TUNITn for a newly created column,
-as shown in the following examples.
-
-\item
-Recompute (overwrite) the values in an existing column or keyword by
-giving the name followed by an equals sign and an arithmetic
-expression.
-\end{itemize}
-
-The expression that is used when appending or recomputing columns or
-keywords can be arbitrarily complex and may be a function of other
-header keyword values and other columns (in the same row).  The full
-syntax and available functions for the expression are described below
-in the row filter specification section.
-
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table 
-except the explicitly deleted columns will appear in the filtered
-table.  If no columns to be deleted are specified, then only the
-columns that are explicitly listed will be included in the filtered
-output table.  To include all the columns, add the '*' wildcard
-specifier at the end of the list, as shown in the examples.
-
-For  complex  or commonly used operations,  one  can  place the
-operations into an external text  file and import it  into the  column
-filter using  the syntax '[col @filename.txt]'.   The operations can
-extend over multiple lines of the  file, but multiple operations must
-still be separated by semicolons.   Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-Examples:
--
-   [col Time; rate]              - only the Time and rate columns will
-                                   appear in the filtered input file.
-
-   [col Time, *raw]              - include the Time column and any other
-                                   columns whose name ends with 'raw'.
-
-   [col -TIME; Good == STATUS]   - deletes the TIME column and
-                                   renames the status column to 'Good'
-
-   [col PI=PHA * 1.1 + 0.2; #TUNIT#(column units) = 'counts';*]
-                                 - creates new PI column from PHA values
-                                   and also writes the TUNITn keyword
-                                   for the new column.  The final '*'
-                                   expression means preserve all the
-                                   columns in the input table in the
-                                   virtual output table;  without the '*'
-                                   the output table would only contain
-                                   the single 'PI' column.
-
-   [col rate = rate/exposure; TUNIT#(&) = 'counts/s';*]
-                                 - recomputes the rate column by dividing
-                                   it by the EXPOSURE keyword value. This
-                                   also modifies the value of the TUNITn
-                                   keyword for this column. The use of the
-                                   '&' character for the keyword comment
-                                   string means preserve the existing
-                                   comment string for that keyword. The
-                                   final '*' preserves all the columns
-                                   in the input table in the virtual
-                                   output table.

-
-**J.  Row Filtering Specification
-
-    When entering the name of a FITS table that is to be opened by a
-    program, an optional row filter may be specified to select a subset
-    of the rows in the table.  A temporary new FITS file is created on
-    the fly which contains only those rows for which the row filter
-    expression evaluates to true.  The primary array and any other
-    extensions in the input file are also copied to the temporary
-    file.  
-(If a `\#' character is appended to the name 
-or number of the 
-table HDU then only the primary array, and none of the other
-HDUs in the input file will be copied into the temporary file).
-    The original FITS file is closed and the new virtual file
-    is opened by the application program.  The row filter expression is
-    enclosed in square brackets following the file name and extension
-    name (e.g., 'file.fits[events][GRADE==50]'  selects only those rows
-    where the GRADE column value equals 50).   When dealing with tables
-    where each row has an associated time and/or 2D spatial position,
-    the row filter expression can also be used to select rows based on
-    the times in a Good Time Intervals (GTI) extension, or on spatial
-    position as given in a SAO-style region file.
-
-***1.  General Syntax
-
-    The row filtering  expression can be an arbitrarily  complex series
-    of operations performed  on constants,  keyword values,  and column
-    data taken from the specified FITS TABLE extension.  The expression
-    must evaluate to a boolean  value for each row  of the table, where
-    a value of FALSE means that the row will be excluded.
-
-    For complex or commonly  used filters, one can place the expression
-    into a text file and import it into the row filter using the syntax
-    '[@filename.txt]'.  The expression can be  arbitrarily complex and
-    extend over multiple lines of the file.  Any lines in the external
-    text file that begin with 2 slash characters ('//') will be ignored
-    and may be used to add comments into the file.
-
-    Keyword and   column data  are referenced by   name.  Any  string of
-    characters not surrounded by    quotes (ie, a constant  string)   or
-    followed by   an open parentheses (ie,   a  function name)   will be
-    initially interpreted   as a column  name and  its contents for the
-    current row inserted into the expression.  If no such column exists,
-    a keyword of that  name will be searched for  and its value used, if
-    found.  To force the  name to be  interpreted as a keyword (in case
-    there is both a column and keyword with the  same name), precede the
-    keyword name with a single pound sign, '\#', as in '\#NAXIS2'.  Due to
-    the generalities of FITS column and  keyword names, if the column or
-    keyword name  contains a space or a  character which might appear as
-    an arithmetic  term then enclose  the  name in '\$'  characters as in
-    \$MAX PHA\$ or \#\$MAX-PHA\$.  Names are case insensitive.
-
-    To access a table entry in a row other  than the current one, follow
-    the  column's name  with  a row  offset  within  curly  braces.  For
-    example, 'PHA\{-3\}' will evaluate to the value  of column PHA, 3 rows
-    above  the  row currently  being processed.   One  cannot specify an
-    absolute row number, only a relative offset.  Rows that fall outside
-    the table will be treated as undefined, or NULLs.
-
-    Boolean   operators can be  used in  the expression  in either their
-    Fortran or C forms.  The following boolean operators are available:
--
-    "equal"         .eq. .EQ. ==  "not equal"          .ne.  .NE.  !=
-    "less than"     .lt. .LT. <   "less than/equal"    .le.  .LE.  <= =<

--
-Three different random number functions are provided:  random(), with
-no arguments, produces a uniform random deviate between 0 and 1;
-randomn(), also with no arguments, produces a normal (Gaussian) random
-deviate  with zero mean and unit standard deviation; randomp(x)
-produces a Poisson random deviate whose expected number of counts is
-X.  X may be any positive real number of expected counts, including
-fractional values, but the return value is an integer.
-
-When the random functions are used in a vector expression, by default
-the same random value will be used when evaluating each element of the vector.
-If different random numbers are desired, then the name of a vector 
-column should be supplied as the single argument to the random 
-function (e.g., "flux + 0.1 * random(flux)", where "flux' is the
-name of a vector column).  This will create a vector of 
-random numbers that will be used in sequence when evaluating each 
-element of the vector expression.
-
-An alternate syntax for the min and max functions  has only a single
-argument which  should be  a  vector value (see  below).  The result
-will be the minimum/maximum element contained within the vector.
-
-The accum(x) function forms the cumulative sum of x, element by element.
-Vector columns are supported simply by performing the summation process
-through all the values.  Null values are treated as 0.  The seqdiff(x) 
-function forms the sequential difference of x, element by element.  
-The first value of seqdiff is the first value of x.  A single null 
-value in x causes a pair of nulls in the output.  The seqdiff and 
-accum functions are functional inverses, i.e., seqdiff(accum(x)) == x
-as long as no null values are present.
-
-In the if-then-else expression, "b?x:y", b is an explicit boolean
-value or expression.  There is no automatic type conversion from
-numeric to boolean values, so one needs to use "iVal!=0" instead of
-merely "iVal" as the boolean argument. x and y can be any scalar data
-type (including string).
-
-The angsep function computes the angular separation in degrees 
-between 2 celestial positions, where the first 2 parameters
-give the RA-like and Dec-like coordinates (in decimal degrees)
-of the first position, and the 3rd and 4th parameters give the
-coordinates of the second position.
-    
-The substring function strmid(S,P,N) extracts a substring from S, 
-starting at string position P, with a substring length N.  The first 
-character position in S is labeled as 1. If P is 0, or refers to a 
-position beyond the end of S, then the extracted substring will be 
-NULL.  S, P, and N may be functions of other columns.
-
-The string search function strstr(S,R) searches for the first occurrence 
-of the substring R in S.  The result is an integer, indicating the 
-character position of the first match (where 1 is the first character 
-position of S).  If no match is found, then strstr() returns a NULL
-value.
-
-The  following  type  casting  operators  are  available,  where the
-inclosing parentheses are required and taken  from  the  C  language
-usage. Also, the integer to real casts values to double precision:
--
-                "real to integer"    (int) x     (INT) x
-                "integer to real"    (float) i   (FLOAT) i
--
-
-    In addition, several constants are built in  for  use  in  numerical
-    expressions:
-
--
-        #pi              3.1415...      #e             2.7182...
-        #deg             #pi/180        #row           current row number
-        #null         undefined value   #snull         undefined string
--
-
-    A  string constant must  be enclosed  in quotes  as in  'Crab'.  The
-    "null" constants  are useful for conditionally  setting table values
-    to a NULL, or undefined, value (eg., "col1==-99 ? \#NULL : col1").
-
-    There is also a function for testing if  two  values  are  close  to
-    each  other,  i.e.,  if  they are "near" each other to within a user
-    specified tolerance. The  arguments,  value\_1  and  value\_2  can  be
-    integer  or  real  and  represent  the two values who's proximity is
-    being tested to be within the specified tolerance, also  an  integer
-    or real:
--
-                    near(value_1, value_2, tolerance)
--
-    When  a  NULL, or undefined, value is encountered in the FITS table,
-    the expression will evaluate to NULL unless the undefined  value  is
-    not   actually   required  for  evaluation,  e.g. "TRUE  .or.  NULL" 
-    evaluates to TRUE. The  following  two  functions  allow  some  NULL
-    detection  and  handling:
--
-         "a null value?"              ISNULL(x)
-         "define a value for null"    DEFNULL(x,y)
--
-    The former
-    returns a boolean value of TRUE if the  argument  x  is  NULL.   The
-    later  "defines"  a  value  to  be  substituted  for NULL values; it
-    returns the value of x if x is not NULL, otherwise  it  returns  the
-    value of y.
-    
-    
-    
-***2.  Bit Masks
-
-    Bit  masks can be used to select out rows from bit columns (TFORMn =
-    \#X) in FITS files. To represent the mask,  binary,  octal,  and  hex
-    formats are allowed:
-
--
-                 binary:   b0110xx1010000101xxxx0001
-                 octal:    o720x1 -> (b111010000xxx001)
-                 hex:      h0FxD  -> (b00001111xxxx1101)
--
-   
-    In  all  the  representations, an x or X is allowed in the mask as a
-    wild card. Note that the x represents a  different  number  of  wild
-    card  bits  in  each  representation.  All  representations are case
-    insensitive.
-    
-    To construct the boolean expression using the mask  as  the  boolean
-    equal  operator  described above on a bit table column. For example,
-    if you had a 7 bit column named flags in a  FITS  table  and  wanted
-    all  rows  having  the bit pattern 0010011, the selection expression
-    would be:
-
--
-                            flags == b0010011
-    or
-                            flags .eq. b10011
--
-
-    It is also possible to test if a range of bits is  less  than,  less
-    than  equal,  greater  than  and  greater than equal to a particular
-    boolean value:
-
--
-                            flags <= bxxx010xx
-                            flags .gt. bxxx100xx
-                            flags .le. b1xxxxxxx
--
-   
-    Notice the use of the x bit value to limit the range of  bits  being
-    compared.
-    
-    It  is  not necessary to specify the leading (most significant) zero
-    (0) bits in the mask, as shown in the second expression above.
-    
-    Bit wise AND, OR and NOT operations are  also  possible  on  two  or
-    more  bit  fields  using  the  '\&'(AND),  '$|$'(OR),  and the '!'(NOT)
-    operators. All of these operators result in a bit  field  which  can
-    then be used with the equal operator. For example:
-
--
-                          (!flags) == b1101100
-                          (flags & b1000001) == bx000001
--
-
-    Bit  fields can be appended as well using the '+' operator.  Strings
-    can be concatenated this way, too.
-
-***3.  Vector Columns
-
-    Vector columns can also be used  in  building  the  expression.   No
-    special  syntax  is required if one wants to operate on all elements
-    of the vector.  Simply use the column name as for a  scalar  column.
-    Vector  columns  can  be  freely  intermixed  with scalar columns or
-    constants in virtually all expressions.  The result will be  of  the
-    same dimension as the vector.  Two vectors in an expression, though,
-    need to  have  the  same  number  of  elements  and  have  the  same
-    dimensions.
-
-    Arithmetic and logical operations are all performed on an element by
-    element basis.  Comparing two vector columns,  eg  "COL1  ==  COL2",
-    thus  results  in  another vector of boolean values indicating which
-    elements of the two vectors are equal.
-
-    Eight functions are available that operate on a vector and return a
-    scalar result:
--
-    "minimum"      MIN(V)          "maximum"               MAX(V)
-    "average"      AVERAGE(V)      "median"                MEDIAN(V)
-    "summation"    SUM(V)          "standard deviation"    STDDEV(V)
-    "# of values"  NELEM(V)        "# of non-null values"  NVALID(V)
--
-    where V represents the name of a vector column or a manually 
-    constructed vector using curly brackets as described below.  The
-    first 6 of these functions ignore any null values in the vector when
-    computing the result.  The STDDEV() function computes the sample 
-    standard deviation, i.e. it is proportional to 1/SQRT(N-1) instead 
-    of 1/SQRT(N), where N is NVALID(V).
-    
-    The SUM function literally sums all  the elements in x,  returning a 
-    scalar value.   If V  is  a  boolean  vector, SUM returns the number
-    of TRUE elements. The NELEM function  returns the number of elements
-    in vector V whereas NVALID return the number of non-null elements in
-    the  vector.   (NELEM  also  operates  on  bit  and string  columns, 
-    returning their column widths.)  As an example, to  test whether all 
-    elements of two vectors satisfy a  given logical comparison, one can
-    use the expression
--
-              SUM( COL1 > COL2 ) == NELEM( COL1 )
--
-
-    which will return TRUE if all elements  of  COL1  are  greater  than
-    their corresponding elements in COL2.
-    
-    To  specify  a  single  element  of  a  vector, give the column name
-    followed by  a  comma-separated  list  of  coordinates  enclosed  in
-    square  brackets.  For example, if a vector column named PHAS exists
-    in the table as a one dimensional, 256  component  list  of  numbers
-    from  which  you  wanted to select the 57th component for use in the
-    expression, then PHAS[57] would do the  trick.   Higher  dimensional
-    arrays  of  data  may appear in a column.  But in order to interpret
-    them, the TDIMn keyword must appear in the header.  Assuming that  a
-    (4,4,4,4)  array  is packed into each row of a column named ARRAY4D,
-    the  (1,2,3,4)  component  element  of  each  row  is  accessed   by 
-    ARRAY4D[1,2,3,4].    Arrays   up   to   dimension  5  are  currently 
-    supported.  Each vector index can itself be an expression,  although
-    it  must  evaluate  to  an  integer  value  within the bounds of the
-    vector.  Vector columns which contain spaces or arithmetic operators
-    must   have   their   names  enclosed  in  "\$"  characters  as  with 
-    \$ARRAY-4D\$[1,2,3,4].
-    
-    A  more  C-like  syntax  for  specifying  vector  indices  is   also 
-    available.   The element used in the preceding example alternatively
-    could be specified with the syntax  ARRAY4D[4][3][2][1].   Note  the
-    reverse  order  of  indices  (as in C), as well as the fact that the
-    values are still ones-based (as  in  Fortran  --  adopted  to  avoid
-    ambiguity  for  1D vectors).  With this syntax, one does not need to
-    specify all of the indices.  To  extract  a  3D  slice  of  this  4D
-    array, use ARRAY4D[4].
-    
-    Variable-length vector columns are not supported.
-    
-    Vectors can  be manually constructed  within the expression  using a
-    comma-separated list of  elements surrounded by curly braces ('\{\}').
-    For example, '\{1,3,6,1\}' is a 4-element vector containing the values
-    1, 3, 6, and 1.  The  vector can contain  only boolean, integer, and
-    real values (or expressions).  The elements will  be promoted to the
-    highest  data type   present.  Any   elements   which  are themselves
-    vectors, will be expanded out with  each of its elements becoming an
-    element in the constructed vector.
-
-***4.  Good Time Interval Filtering
-
-    A common filtering method involves selecting rows which have a time
-    value which lies within what is called a Good Time Interval or GTI.
-    The time intervals are defined in a separate FITS table extension
-    which contains 2 columns giving the start and stop time of each
-    good interval.  The filtering operation accepts only those rows of
-    the input table which have an associated time which falls within
-    one of the time intervals defined in the GTI extension. A high
-    level function, gtifilter(a,b,c,d), is available which evaluates
-    each row of the input table  and returns TRUE  or FALSE depending
-    whether the row is inside or outside the  good time interval.  The
-    syntax is
--
-      gtifilter( [ "gtifile" [, expr [, "STARTCOL", "STOPCOL" ] ] ] )
-    or
-      gtifilter( [ 'gtifile' [, expr [, 'STARTCOL', 'STOPCOL' ] ] ] )
--
-    where  each "[]" demarks optional parameters.  Note that  the quotes
-    around the gtifile and START/STOP column are required.  Either single
-    or double quotes may be used.  In cases where this expression is 
-    entered on the Unix command line, enclose the entire expression in
-    double quotes, and then use single quotes within the expression to
-    enclose the 'gtifile' and other terms.  It is also usually possible
-    to do the reverse, and enclose the whole expression in single quotes
-    and then use double quotes within the expression.  The gtifile,
-    if specified,  can be blank  ("") which will  mean to use  the first
-    extension  with   the name "*GTI*"  in   the current  file,  a plain
-    extension  specifier (eg, "+2",  "[2]", or "[STDGTI]") which will be
-    used  to  select  an extension  in  the current  file, or  a regular
-    filename with or without an extension  specifier which in the latter
-    case  will mean to  use the first  extension  with an extension name
-    "*GTI*".  Expr can be   any arithmetic expression, including  simply
-    the time  column  name.  A  vector  time expression  will  produce a
-    vector boolean  result.  STARTCOL and  STOPCOL are the  names of the
-    START/STOP   columns in the    GTI extension.  If   one  of them  is
-    specified, they both  must be.
-
-    In  its  simplest form, no parameters need to be provided -- default
-    values will be used.  The expression "gtifilter()" is equivalent to
--   
-       gtifilter( "", TIME, "*START*", "*STOP*" )
--    
-    This will search the current file for a GTI  extension,  filter  the
-    TIME  column in the current table, using START/STOP times taken from
-    columns in the GTI  extension  with  names  containing  the  strings
-    "START"  and "STOP".  The wildcards ('*') allow slight variations in
-    naming conventions  such  as  "TSTART"  or  "STARTTIME".   The  same
-    default  values  apply for unspecified parameters when the first one
-    or  two  parameters  are  specified.   The  function   automatically 
-    searches   for   TIMEZERO/I/F   keywords  in  the  current  and  GTI 
-    extensions, applying a relative time offset, if necessary.
-
-***5.  Spatial Region Filtering
-
-    Another common  filtering method selects rows based on whether the
-    spatial position associated with each row is located within a given 
-    2-dimensional region.  The syntax for this high-level filter is
--
-       regfilter( "regfilename" [ , Xexpr, Yexpr [ , "wcs cols" ] ] )
--
-    where each "[]" demarks optional parameters. The region file name
-    is required and must be  enclosed in quotes.  The remaining
-    parameters are optional.  There are 2 supported formats for the
-    region file: ASCII file or FITS binary table.  The region file 
-    contains a list of one or more geometric shapes (circle,
-    ellipse, box, etc.) which defines a region on the celestial sphere
-    or an area within a particular 2D image.  The region file is
-    typically generated using an image display program such as fv/POW
-    (distribute by the HEASARC), or ds9 (distributed by the Smithsonian
-    Astrophysical Observatory).  Users should refer to the documentation
-    provided with these programs for more details on the syntax used in
-    the region files.  The FITS region file format is defined in a document
-    available from the FITS Support Office at 
-    http://fits.gsfc.nasa.gov/ registry/ region.html
-
-    In its simplest form, (e.g., regfilter("region.reg") ) the
-    coordinates in the default 'X' and 'Y' columns will be used to
-    determine if each row is inside or outside the area specified in
-    the region file.  Alternate position column names, or expressions,
-    may be entered if needed, as in
--
-        regfilter("region.reg", XPOS, YPOS)
--
-    Region filtering can be applied most unambiguously if the positions
-    in the region file and in the table to be filtered are both give in
-    terms of absolute celestial coordinate units.  In this case the
-    locations and sizes of the geometric shapes in the region file are
-    specified in angular units on the sky (e.g., positions given in
-    R.A. and Dec.  and sizes in arcseconds or arcminutes).  Similarly,
-    each row of the filtered table will have a celestial coordinate
-    associated with it.  This association is usually implemented using
-    a set of so-called 'World Coordinate System' (or WCS) FITS keywords
-    that define the coordinate transformation that must be applied to
-    the values in the 'X' and 'Y' columns to calculate the coordinate.
-
-    Alternatively, one can perform spatial filtering using unitless
-    'pixel' coordinates for the regions and row positions.  In this
-    case the user must be careful to ensure that the positions in the 2
-    files are self-consistent.  A typical problem is that the region
-    file may be generated using a binned image, but the unbinned
-    coordinates are given in the event table.  The ROSAT events files,
-    for example, have X and Y pixel coordinates that range from 1 -
-    15360.  These coordinates are typically binned by a factor of 32 to
-    produce a 480x480 pixel image.  If one then uses a region file
-    generated from this image (in image pixel units) to filter the
-    ROSAT events file, then the X and Y column values must be converted
-    to corresponding pixel units as in:
--
-        regfilter("rosat.reg", X/32.+.5, Y/32.+.5)
--
-    Note that this binning conversion is not necessary if the region
-    file is specified using celestial coordinate units instead of pixel
-    units because CFITSIO is then able to directly compare the
-    celestial coordinate of each row in the table with the celestial
-    coordinates in the region file without having to know anything
-    about how the image may have been binned.
-
-    The last "wcs cols" parameter should rarely be needed. If supplied,
-    this  string contains the names of the 2 columns (space or comma
-    separated) which have the associated WCS keywords. If not supplied,
-    the filter  will scan the X  and Y expressions for column names.
-    If only one is found in each  expression, those columns will be
-    used, otherwise an error will be returned.
-
-    These region shapes are supported (names are case insensitive):
--
-       Point         ( X1, Y1 )               <- One pixel square region
-       Line          ( X1, Y1, X2, Y2 )       <- One pixel wide region
-       Polygon       ( X1, Y1, X2, Y2, ... )  <- Rest are interiors with
-       Rectangle     ( X1, Y1, X2, Y2, A )       | boundaries considered
-       Box           ( Xc, Yc, Wdth, Hght, A )   V within the region
-       Diamond       ( Xc, Yc, Wdth, Hght, A )
-       Circle        ( Xc, Yc, R )
-       Annulus       ( Xc, Yc, Rin, Rout )
-       Ellipse       ( Xc, Yc, Rx, Ry, A )
-       Elliptannulus ( Xc, Yc, Rinx, Riny, Routx, Routy, Ain, Aout )
-       Sector        ( Xc, Yc, Amin, Amax )

-    where (Xc,Yc) is  the coordinate of  the shape's center; (X\#,Y\#) are
-    the coordinates  of the shape's edges;  Rxxx are the shapes' various
-    Radii or semimajor/minor  axes; and Axxx  are the angles of rotation
-    (or bounding angles for Sector) in degrees.  For rotated shapes, the
-    rotation angle  can  be left  off, indicating  no rotation.   Common
-    alternate  names for the regions  can also be  used: rotbox = box;
-    rotrectangle = rectangle;  (rot)rhombus = (rot)diamond;  and pie
-    = sector.  When a  shape's name is  preceded by a minus sign, '-',
-    the defined region  is instead the area  *outside* its boundary (ie,
-    the region is inverted).  All the shapes within a single region
-    file are OR'd together to create the region, and the order is
-    significant. The overall way of looking at region files is that if
-    the first region is an excluded region then a dummy included region
-    of the whole detector is inserted in the front. Then each region
-    specification as it is processed overrides any selections inside of
-    that region specified by previous regions. Another way of thinking
-    about this is that if a previous excluded region is completely
-    inside of a subsequent included region the excluded region is
-    ignored.
-
-    The positional coordinates may be given either in pixel units,
-    decimal degrees or hh:mm:ss.s, dd:mm:ss.s units.  The shape sizes
-    may be given in pixels, degrees, arcminutes, or arcseconds.  Look
-    at examples of region file produced by fv/POW or ds9 for further
-    details of the region file format.
-
-    There are three low-level  functions that are primarily for use with 
-    regfilter function, but they  can  be  called  directly.  They
-    return  a  boolean true   or  false  depending   on  whether a   two
-    dimensional point is in the region or not.  The positional coordinates
-    must be given in pixel units:
--
-    "point in a circular region"
-          circle(xcntr,ycntr,radius,Xcolumn,Ycolumn)
-    
-    "point in an elliptical region"
-         ellipse(xcntr,ycntr,xhlf_wdth,yhlf_wdth,rotation,Xcolumn,Ycolumn)
-    
-    "point in a rectangular region"
-             box(xcntr,ycntr,xfll_wdth,yfll_wdth,rotation,Xcolumn,Ycolumn)
-    
-    where 
-       (xcntr,ycntr) are the (x,y) position of the center of the region
-       (xhlf_wdth,yhlf_wdth) are the (x,y) half widths of the region
-       (xfll_wdth,yfll_wdth) are the (x,y) full widths of the region
-       (radius) is half the diameter of the circle
-       (rotation) is the angle(degrees) that the region is rotated with
-             respect to (xcntr,ycntr)
-       (Xcoord,Ycoord) are the (x,y) coordinates to test, usually column
-             names
-       NOTE: each parameter can itself be an expression, not merely a
-             column name or constant.

-**J.   Binning or Histogramming Specification
-
-The optional binning specifier is enclosed in square brackets and can
-be distinguished from a general row filter specification by the fact
-that it begins with the keyword 'bin'  not immediately followed by an
-equals sign.  When binning is specified, a temporary N-dimensional FITS
-primary array is created by computing the histogram of the values in
-the specified columns of a FITS table extension.  After the histogram
-is computed the input FITS file containing the table is then closed and
-the temporary FITS primary array is opened and passed to the
-application program.  Thus, the application program never sees the
-original FITS table and only sees the image in the new temporary file
-(which has no additional extensions).  Obviously, the application
-program must be expecting to open a FITS image and not a FITS table in
-this case.
-
-The data type of the FITS histogram image may be specified by appending
-'b' (for 8-bit byte), 'i' (for 16-bit integers), 'j' (for 32-bit
-integer), 'r' (for 32-bit floating points), or 'd' (for 64-bit double
-precision floating point)  to the 'bin' keyword (e.g. '[binr X]'
-creates a real floating point image).  If the data type is not
-explicitly specified then a 32-bit integer image will be created by
-default, unless the weighting option is also specified in which case
-the image will have a 32-bit floating point data type by default.
-
-The histogram image may have from 1 to 4 dimensions (axes), depending
-on the number of columns that are specified.  The general form of the
-binning specification is:
--
- [bin{bijrd}  Xcol=min:max:binsize, Ycol= ..., Zcol=..., Tcol=...; weight]
--
-in which up to 4 columns, each corresponding to an axis of the image,
-are listed. The column names are case insensitive, and the column
-number may be given instead of the name, preceded by a pound sign
-(e.g., [bin \#4=1:512]).  If the column name is not specified, then
-CFITSIO will first try to use the 'preferred column' as specified by
-the CPREF keyword if it exists (e.g., 'CPREF = 'DETX,DETY'), otherwise
-column names 'X', 'Y', 'Z', and 'T' will be assumed for each of the 4
-axes, respectively.  In cases where the column name could be confused
-with an arithmetic expression, enclose the column name in parentheses to
-force the name to be interpreted literally.
-
-Each column name may be followed by an equals sign and then the lower
-and upper range of the histogram, and the size of the histogram bins,
-separated by colons.  Spaces are allowed before and after the equals
-sign but not within the 'min:max:binsize' string.  The min, max and
-binsize values may be integer or floating point numbers, or they may be
-the names of keywords in the header of the table.  If the latter, then
-the value of that keyword is substituted into the expression.
-
-Default values for the min, max and binsize quantities will be
-used if not explicitly given in the binning expression as shown
-in these examples:
--
-    [bin x = :512:2]  - use default minimum value
-    [bin x = 1::2]    - use default maximum value
-    [bin x = 1:512]   - use default bin size
-    [bin x = 1:]      - use default maximum value and bin size
-    [bin x = :512]    - use default minimum value and bin size
-    [bin x = 2]       - use default minimum and maximum values
-    [bin x]           - use default minimum, maximum and bin size
-    [bin 4]           - default 2-D image, bin size = 4 in both axes
-    [bin]             - default 2-D image
--
-CFITSIO  will use the value of the TLMINn, TLMAXn, and TDBINn keywords,
-if they exist, for the default min, max, and binsize, respectively.  If
-they do not exist then CFITSIO will use the actual minimum and maximum
-values in the column for the histogram min and max values.  The default
-binsize will be set to 1, or (max - min) / 10., whichever is smaller,
-so that the histogram will have at least 10 bins along each axis.
-
-A shortcut notation is allowed if all the columns/axes have the same
-binning specification.  In this case all the column names may be listed
-within parentheses, followed by the (single) binning specification, as
-in:
--
-    [bin (X,Y)=1:512:2]
-    [bin (X,Y) = 5]
--
-
-The optional weighting factor is the last item in the binning specifier
-and, if present, is separated from the list of columns by a
-semi-colon.  As the histogram is accumulated, this weight is used to
-incremented the value of the appropriated bin in the histogram.  If the
-weighting factor is not specified, then the default weight = 1 is
-assumed.  The weighting factor may be a constant integer or floating
-point number, or the name of a keyword containing the weighting value.
-Or the weighting factor may be the name of a table column in which case
-the value in that column, on a row by row basis, will be used.
-
-In some cases, the column or keyword may give the reciprocal of the
-actual weight value that is needed.  In this case, precede the weight
-keyword or column name by a slash '/' to tell CFITSIO to use the
-reciprocal of the value when constructing the histogram. 
-
-For  complex or commonly  used  histograms, one  can also  place its
-description  into  a  text  file and  import   it  into  the binning
-specification  using the  syntax [bin  @filename.txt].  The file's
-contents  can extend over   multiple lines, although  it must still
-conform to the  no-spaces rule  for the min:max:binsize syntax and each
-axis specification must still be comma-separated.  Any lines in the
-external text file that begin with 2 slash characters ('//') will be
-ignored and may be used to add comments into the file.
-
- Examples:
-
--
-    [bini detx, dety]                - 2-D, 16-bit integer histogram
-                                       of DETX and DETY columns, using
-                                       default values for the histogram
-                                       range and binsize
-
-    [bin (detx, dety)=16; /exposure] - 2-D, 32-bit real histogram of DETX
-                                       and DETY columns with a bin size = 16
-                                       in both axes. The histogram values
-                                       are divided by the EXPOSURE keyword
-                                       value.
-
-    [bin time=TSTART:TSTOP:0.1]      - 1-D lightcurve, range determined by
-                                       the TSTART and TSTOP keywords, 
-                                       with 0.1 unit size bins.  
- 
-    [bin pha, time=8000.:8100.:0.1]  - 2-D image using default binning
-                                       of the PHA column for the X axis,
-                                       and 1000 bins in the range 
-                                       8000. to 8100. for the Y axis.
-    
-    [bin @binFilter.txt]             - Use the contents of the text file
-                                       binFilter.txt for the binning
-                                       specifications.

-*X.  Template Files
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described in the following sections.
-
-**A   Detailed Template Line Format
-
-The format of each ASCII template line closely follows the format of a
-FITS keyword record:
--
-  KEYWORD = KEYVALUE / COMMENT
--
-except that free format may be used (e.g., the equals sign may appear
-at any position in the line) and TAB characters are allowed and are
-treated the same as space characters.  The KEYVALUE and COMMENT fields
-are optional.  The equals sign character is also optional, but it is
-recommended that it be included for clarity.  Any template line that
-begins with the pound '\#' character is ignored by the template parser
-and may be use to insert comments into the template file itself.
-
-The KEYWORD name field is limited to 8 characters in length and only
-the letters A-Z, digits 0-9, and the hyphen and underscore characters
-may be used, without any embedded spaces. Lowercase letters in the
-template keyword name will be converted to uppercase.  Leading spaces
-in the template line preceding the keyword name are generally ignored,
-except if the first 8 characters of a template line are all blank, then
-the entire line is treated as a FITS comment keyword (with a blank
-keyword name) and is copied verbatim into the FITS header.
-
-The KEYVALUE field may have any allowed  FITS  data type: character
-string, logical, integer, real, complex integer, or complex real.  The
-character string values need not be enclosed in single quote characters
-unless they are necessary to distinguish the string from a different
-data type (e.g.  2.0 is a real but '2.0' is a string).  The keyword has
-an undefined (null) value if the template record only contains blanks
-following the "=" or between the "=" and the "/" comment field
-delimiter.
-
-String keyword values longer than 68 characters (the maximum length
-that will fit in a single FITS keyword record) are permitted using the
-CFITSIO long string convention. They can either be specified as a
-single long line in the template, or by using multiple lines where the
-continuing lines contain the 'CONTINUE' keyword, as in this example:
-- 
-  LONGKEY = 'This is a long string value that is contin&'
-  CONTINUE  'ued over 2 records' / comment field goes here
--
-The format of template lines with CONTINUE keyword is very strict:  3
-spaces must follow CONTINUE and the rest of the line is copied verbatim
-to the FITS file.
-
-The start of the optional COMMENT field must be preceded by "/", which
-is used to separate it from the keyword value field. Exceptions are if
-the KEYWORD name field contains COMMENT, HISTORY, CONTINUE, or if the
-first 8 characters of the template line are blanks.
-
-More than one Header-Data Unit (HDU) may be defined in the template
-file.  The start of an HDU definition is denoted with a SIMPLE or
-XTENSION template line:
-
-1) SIMPLE begins a Primary HDU definition. SIMPLE may only appear as
-the  first keyword in the template file. If the template file begins
-with XTENSION instead of SIMPLE, then a default empty Primary HDU is
-created, and the template is then assumed to define the keywords
-starting with the first extension following the Primary HDU.
-
-2) XTENSION marks the beginning of a new extension HDU definition.  The
-previous HDU will be closed at this point and processing of the next
-extension begins.
-
-**B   Auto-indexing of Keywords
-
-If a template keyword name ends with a "\#" character, it is said to be
-'auto-indexed'.   Each "\#" character will be replaced by the current
-integer index value, which gets reset = 1 at the start of each new HDU
-in the file (or 7 in the special case of a GROUP definition).  The
-FIRST indexed keyword in each template HDU definition is used as the
-'incrementor';  each subsequent occurrence of this SAME keyword will
-cause the index value to be incremented.  This behavior can be rather
-subtle, as illustrated in the following examples in which the TTYPE
-keyword is the incrementor in both cases:
--
-  TTYPE# = TIME
-  TFORM# = 1D
-  TTYPE# = RATE
-  TFORM# = 1E
--
-will create TTYPE1, TFORM1, TTYPE2, and TFORM2 keywords.  But if the
-template looks like,
--
-  TTYPE# = TIME
-  TTYPE# = RATE
-  TFORM# = 1D
-  TFORM# = 1E
--
-this results in a FITS files with  TTYPE1, TTYPE2, TFORM2, and TFORM2,
-which is probably not what was intended!
-
-**C   Template Parser Directives
-
-In addition to the template lines which define individual keywords, the
-template parser recognizes 3 special directives which are each preceded
-by the backslash character:  \verb+ \include, \group+, and \verb+ \end+.
-
-The 'include' directive must be followed by a filename. It forces the
-parser to temporarily stop reading the current template file and begin
-reading the include file. Once the parser reaches the end of the
-include file it continues parsing the current template file.  Include
-files can be nested, and HDU definitions can span multiple template
-files.
-
-The start of a GROUP definition is denoted with the 'group' directive,
-and the end of a GROUP definition is denoted with the 'end' directive.
-Each GROUP contains 0 or more member blocks (HDUs or GROUPs). Member
-blocks of type GROUP can contain their own member blocks. The GROUP
-definition itself occupies one FITS file HDU of special type (GROUP
-HDU), so if a template specifies 1 group with 1 member HDU like:
--
-\group
-grpdescr = 'demo'
-xtension bintable
-# this bintable has 0 cols, 0 rows
-\end
--
-then the parser creates a FITS file with 3 HDUs :
--
-1) dummy PHDU
-2) GROUP HDU (has 1 member, which is bintable in HDU number 3)
-3) bintable (member of GROUP in HDU number 2)
--
-Technically speaking, the GROUP HDU is a BINTABLE with 6 columns. Applications
-can define additional columns in a GROUP HDU using TFORMn and TTYPEn
-(where n is 7, 8, ....) keywords or their auto-indexing equivalents.
-
-For a more complicated example of a template file using the group directives,
-look at the sample.tpl file that is included in the CFITSIO distribution.
-
-**D   Formal Template Syntax
-
-The template syntax can formally be defined as follows:
--
-    TEMPLATE = BLOCK [ BLOCK ... ]
-
-       BLOCK = { HDU | GROUP }
-
-       GROUP = \GROUP [ BLOCK ... ] \END
-
-         HDU = XTENSION [ LINE ... ] { XTENSION | \GROUP | \END | EOF }
-
-        LINE = [ KEYWORD [ = ] ] [ VALUE ] [ / COMMENT ]
-
-    X ...     - X can be present 1 or more times
-    { X | Y } - X or Y
-    [ X ]     - X is optional
--
-
-At the topmost level, the template defines 1 or more template blocks. Blocks
-can be either HDU (Header Data Unit) or a GROUP. For each block the parser
-creates 1 (or more for GROUPs) FITS file HDUs.
-
-
-**E   Errors
-
-In general the fits\_execute\_template() function tries to be as atomic
-as possible, so either everything is done or nothing is done. If an
-error occurs during parsing of the template, fits\_execute\_template()
-will (try to) delete the top level BLOCK (with all its children if any)
-in which the error occurred, then it will stop reading the template file
-and it will return with an error.
-
-**F   Examples
-
-1. This template file will create a 200 x 300 pixel image, with 4-byte
-integer pixel values, in the primary HDU:
--
-  SIMPLE = T 
-  BITPIX = 32
-  NAXIS = 2     / number of dimensions
-  NAXIS1 = 100  / length of first axis
-  NAXIS2 = 200  / length of second axis
-  OBJECT = NGC 253 / name of observed object
--
-The allowed values of BITPIX are 8, 16, 32, -32, or -64,
-representing, respectively, 8-bit integer, 16-bit integer, 32-bit
-integer, 32-bit floating point, or 64 bit floating point pixels.
-
-2.  To create a FITS  table, the template first needs to include
-XTENSION = TABLE or BINTABLE to define whether it is an ASCII or binary
-table, and NAXIS2 to define the number of rows in the table.  Two
-template lines are then needed to define the name (TTYPEn) and FITS data
-format (TFORMn) of the columns, as in this example:
--
-  xtension = bintable
-  naxis2 = 40
-  ttype# = Name
-  tform# = 10a
-  ttype# = Npoints
-  tform# = j
-  ttype# = Rate
-  tunit# = counts/s
-  tform# = e
--
-The above example defines a null primary array followed by a 40-row
-binary table extension with 3 columns called 'Name', 'Npoints', and
-'Rate', with data formats of '10A' (ASCII character string), '1J'
-(integer) and '1E' (floating point), respectively.  Note that the other
-required FITS keywords (BITPIX, NAXIS, NAXIS1, PCOUNT, GCOUNT, TFIELDS,
-and END) do not need to be explicitly defined in the template because
-their values can be inferred from the other keywords in the template.
-This example also illustrates that the templates are generally
-case-insensitive (the keyword names and TFORMn values are converted to
-upper-case in the FITS file) and that string keyword values generally
-do not need to be enclosed in quotes.
-
-*XI.   Local FITS Conventions
-
-CFITSIO supports several local FITS conventions which are not
-defined in the official NOST FITS standard and which are not
-necessarily recognized or supported by other FITS software packages.
-Programmers should be cautious about using these features, especially
-if the FITS files that are produced are expected to be processed by
-other software systems which do not use the CFITSIO interface.  
-
-**A.  64-Bit Long Integers
-
-CFITSIO supports reading and writing FITS images or table columns containing
-64-bit integer data values. Support for 64-bit integers was added to the
-official FITS Standard in December 2005.
- FITS 64-bit images have BITPIX =
-64, and the 64-bit binary table columns have TFORMn = 'K'.  CFITSIO also
-supports the 'Q' variable-length array table column format which is
-analogous to the 'P' column format except that the array descriptor
-is stored as a pair of 64-bit integers.
-
-For the convenience of C programmers, the fitsio.h include file 
-defines (with a typedef statement) the 'LONGLONG' datatype to be 
-equivalent to an appropriate 64-bit integer datatype on each platform.  
-Since there is currently no universal standard
-for the name of the 64-bit integer datatype (it might be defined as
-'long long', 'long', or '\_\_int64' depending on the platform)
-C programmers may prefer to use the 'LONGLONG' datatype when 
-declaring or allocating 64-bit integer quantities when writing
-code which needs to run on multiple platforms.
-Note that CFITSIO will implicitly convert the datatype when reading
-or writing FITS 64-bit integer images and columns with data arrays of
-a different integer or floating point datatype, but there is an
-increased risk of loss of numerical precision or
-numerical overflow  in this case.
-
-**B.  Long String Keyword Values.
- 
-The length of a standard FITS string keyword is limited to 68
-characters because it must fit entirely within a single FITS header
-keyword record.  In some instances it is necessary to encode strings
-longer than this limit, so CFITSIO supports a local convention in which
-the string value is continued over multiple keywords.  This
-continuation convention uses an ampersand character at the end of each
-substring to indicate that it is continued on the next keyword, and the
-continuation keywords all have the name CONTINUE without an equal sign
-in column 9. The string value may be continued in this way over as many
-additional CONTINUE keywords as is required.  The following lines
-illustrate this continuation convention which is used in the value of
-the STRKEY keyword:
--
-LONGSTRN= 'OGIP 1.0'    / The OGIP Long String Convention may be used.
-STRKEY  = 'This is a very long string keyword&'  / Optional Comment
-CONTINUE  ' value that is continued over 3 keywords in the &  '
-CONTINUE  'FITS header.' / This is another optional comment.
--
-It is recommended that the LONGSTRN keyword, as shown here, always be
-included in any HDU that uses this longstring convention as a warning
-to any software that must read the keywords.  A routine called fits\_write\_key\_longwarn
-has been provided in CFITSIO to write this keyword if it does not
-already exist.
-
-This long string convention is supported by the following CFITSIO
-routines:
--
-    fits_write_key_longstr  - write a long string keyword value
-    fits_insert_key_longstr - insert a long string keyword value
-    fits_modify_key_longstr - modify a long string keyword value
-    fits_update_key_longstr - modify a long string keyword value
-    fits_read_key_longstr   - read  a long string keyword value
-    fits_delete_key         - delete a keyword
--
-The fits\_read\_key\_longstr routine is unique among all the CFITSIO
-routines in that it internally allocates memory for the long string
-value;  all the other CFITSIO routines that deal with arrays require
-that the calling program pre-allocate adequate space to hold the array
-of data.  Consequently, programs which use the fits\_read\_key\_longstr
-routine must be careful to free the allocated memory for the string
-when it is no longer needed.
-
-The following 2 routines also have limited support for this long string
-convention,
--
-      fits_modify_key_str - modify an existing string keyword value
-      fits_update_key_str - update a string keyword value
--
-in that they will correctly overwrite an existing long string value,
-but the new string value is limited to a maximum of 68 characters in
-length.
-
-The more commonly used CFITSIO routines to write string valued keywords
-(fits\_update\_key and fits\_write\_key) do not support this long
-string convention and only support strings up to 68 characters in
-length.  This has been done deliberately to prevent programs from
-inadvertently writing keywords using this non-standard convention
-without the explicit intent of the programmer or user.   The
-fits\_write\_key\_longstr routine must be called instead to write long
-strings.  This routine can also be used to write ordinary string values
-less than 68 characters in length.
-
-**C.  Arrays of Fixed-Length Strings in Binary Tables
-
-CFITSIO supports 2 ways to specify that a character column in a binary
-table contains an array of fixed-length strings.  The first way, which
-is officially supported by the FITS Standard document, uses the TDIMn keyword.
-For example, if TFORMn = '60A' and TDIMn = '(12,5)' then that 
-column will be interpreted as containing an array of 5 strings, each 12
-characters long.
-
-CFITSIO also supports a 
-local convention for the format of the TFORMn keyword value of the form
-'rAw' where 'r' is an integer specifying the total width in characters
-of the column, and 'w' is an integer specifying the (fixed) length of
-an individual unit string within the vector.  For example, TFORM1 =
-'120A10' would indicate that the binary table column is 120 characters
-wide and consists of 12 10-character length strings.  This convention
-is recognized by the CFITSIO routines that read or write strings in
-binary tables.   The Binary Table definition document specifies that
-other optional characters may follow the data type code in the TFORM
-keyword, so this local convention is in compliance with the
-FITS standard although other FITS readers may not
-recognize this convention.
-
-The Binary Table definition document that was approved by the IAU in
-1994 contains an appendix describing an alternate convention for
-specifying arrays of fixed or variable length strings in a binary table
-character column (with the form 'rA:SSTRw/nnn)'.  This appendix was not
-officially voted on by the IAU and hence is still provisional.  CFITSIO
-does not currently support this proposal.
-
-**D.  Keyword Units Strings
-
-One limitation of the current FITS Standard is that it does not define
-a specific convention for recording the physical units of a keyword
-value.  The TUNITn keyword can be used to specify the physical units of
-the values in a table column, but there is no analogous convention for
-keyword values.  The comment field of the keyword is often used for
-this purpose, but the units are usually not specified in a well defined
-format that FITS readers can easily recognize and extract.
-
-To solve this problem, CFITSIO uses a local convention in which the
-keyword units are enclosed in square brackets as the first token in the
-keyword comment field; more specifically, the opening square bracket
-immediately follows the slash '/' comment field delimiter and a single
-space character.  The following examples illustrate keywords that use
-this convention:
-
--
-EXPOSURE=               1800.0 / [s] elapsed exposure time
-V_HELIO =                16.23 / [km s**(-1)] heliocentric velocity
-LAMBDA  =                5400. / [angstrom] central wavelength
-FLUX    = 4.9033487787637465E-30 / [J/cm**2/s] average flux
--
-
-In general, the units named in the IAU(1988) Style Guide are
-recommended, with the main exception that the preferred unit for angle
-is 'deg' for degrees.
-
-The fits\_read\_key\_unit and fits\_write\_key\_unit routines in
-CFITSIO read and write, respectively, the keyword unit strings in an
-existing keyword.
-
-**E.  HIERARCH Convention for Extended Keyword Names
-
-CFITSIO supports the HIERARCH keyword convention which allows keyword
-names that are longer then 8 characters and may contain the full range
-of printable ASCII text characters.  This convention 
-was developed at the European Southern Observatory (ESO)  to support 
-hierarchical FITS keyword such as:
--
-HIERARCH ESO INS FOCU POS = -0.00002500 / Focus position
--
-Basically, this convention uses the FITS keyword 'HIERARCH' to indicate
-that this convention is being used, then the actual keyword name
-({\tt'ESO INS FOCU POS'} in this example) begins in column 10 and can
-contain any printable ASCII text characters, including spaces.  The
-equals sign marks the end of the keyword name and is followed by the
-usual value and comment fields just as in standard FITS keywords.
-Further details of this convention are described at
-http://arcdev.hq.eso.org/dicb/dicd/dic-1-1.4.html (search for
-HIERARCH).
-
-This convention allows a much broader range of keyword names 
-than is allowed by the FITS Standard.  Here are more examples
-of such keywords:
--
-HIERARCH LongKeyword = 47.5 / Keyword has > 8 characters, and mixed case
-HIERARCH XTE$TEMP = 98.6 / Keyword contains the '$' character
-HIERARCH Earth is a star = F / Keyword contains embedded spaces
--
-CFITSIO will transparently read and write these keywords, so application
-programs do not in general need to know anything about the specific
-implementation details of the HIERARCH convention.  In particular,
-application programs do not need to specify the `HIERARCH' part of the
-keyword name when reading or writing keywords (although it
-may be included if desired).  When writing a keyword, CFITSIO first
-checks to see if the keyword name is legal as a standard FITS keyword
-(no more than 8 characters long and containing only letters, digits, or
-a minus sign or underscore). If so it writes it as a standard FITS
-keyword, otherwise it uses the hierarch convention to write the
-keyword.   The maximum keyword name length is 67 characters, which
-leaves only 1 space for the value field.  A more practical limit is
-about 40 characters, which leaves enough room for most keyword values.
-CFITSIO returns an error if there is not enough room for both the
-keyword name and the keyword value on the 80-character card, except for
-string-valued keywords which are simply truncated so that the closing
-quote character falls in column 80.  In the current implementation,
-CFITSIO preserves the case of the letters when writing the keyword
-name, but it is case-insensitive when reading or searching for a
-keyword.  The current implementation allows any ASCII text character
-(ASCII 32 to ASCII 126) in the keyword name except for the '='
-character.  A space is also required on either side of the equal sign.
-
-**F.  Tile-Compressed Image Format
-
-CFITSIO supports a convention for compressing n-dimensional images and
-storing the resulting byte stream in a variable-length column in a FITS
-binary table.  The general principle used in this convention is to
-first divide the n-dimensional image into a rectangular grid of
-subimages or `tiles'.  Each tile is then compressed as a continuous
-block of data, and the resulting compressed byte stream is stored in a
-row of a variable length column in a FITS binary table. By dividing the
-image into tiles it is generally possible to extract and uncompress
-subsections of the image without having to uncompress the whole image.
-The default tiling pattern treats each row of a 2-dimensional image (or
-higher dimensional cube) as a tile, such that each tile contains NAXIS1
-pixels (except the default with the HCOMPRESS algorithm is to
-compress the whole 2D image as a single tile). Any other rectangular 
-tiling pattern may also be defined. In
-the case of relatively small images it may be sufficient to compress
-the entire image as a single tile, resulting in an output binary table
-with 1 row.  In the case of 3-dimensional data cubes, it may be
-advantageous to treat each plane of the cube as a separate tile if
-application software typically needs to access the cube on a plane by
-plane basis.
-
-See section 5.6 ``Image Compression''
-for more information on using this tile-compressed image format.
-
-*XII.  Optimizing Programs
- 
-CFITSIO has been carefully designed to obtain the highest possible
-speed when reading and writing FITS files.  In order to achieve the
-best performance, however, application programmers must be careful to
-call the CFITSIO routines appropriately and in an efficient sequence;
-inappropriate usage of CFITSIO routines can greatly slow down the
-execution speed of a program.
-
-The maximum possible I/O speed of CFITSIO depends of course on the type
-of computer system that it is running on.  As a rough guide, the
-current generation of workstations can achieve speeds of 2 -- 10 MB/s
-when reading or writing FITS images and similar, or slightly slower
-speeds with FITS binary tables.  Reading of FITS files can occur at
-even higher rates (30MB/s or more) if the FITS file is still cached in
-system memory following a previous read or write operation on the same
-file.  To more accurately predict the best performance that is possible
-on any particular system, a diagnostic program called ``speed.c'' is
-included with the CFITSIO distribution which can be run to
-approximately measure the maximum possible speed of writing and reading
-a test FITS file.
-
-The following 2 sections provide some background on how CFITSIO
-internally manages the data I/O and describes some strategies that may
-be used to optimize the processing speed of software that uses
-CFITSIO.
-
-**A.  How CFITSIO Manages Data I/O
-
-Many CFITSIO operations involve transferring only a small number of
-bytes to or from the FITS file (e.g, reading a keyword, or writing a
-row in a table); it would be very inefficient to physically read or
-write such small blocks of data directly in the FITS file on disk,
-therefore CFITSIO maintains a set of internal Input--Output (IO)
-buffers in RAM memory that each contain one FITS block (2880 bytes) of
-data.  Whenever CFITSIO needs to access data in the FITS file, it first
-transfers the FITS block containing those bytes into one of the IO
-buffers in memory.  The next time CFITSIO needs to access bytes in the
-same block it can then go to the fast IO buffer rather than using a
-much slower system disk access routine.  The number of available IO
-buffers is determined by the NIOBUF parameter (in fitsio2.h) and is
-currently set to 40 by default.
-
-Whenever CFITSIO reads or writes data it first checks to see if that
-block of the FITS file is already loaded into one of the IO buffers.
-If not, and if there is an empty IO buffer available, then it will load
-that block into the IO buffer (when reading a FITS file) or will
-initialize a new block (when writing to a FITS file).  If all the IO
-buffers are already full, it must decide which one to reuse (generally
-the one that has been accessed least recently), and flush the contents
-back to disk if it has been modified before loading the new block.
-
-The one major exception to the above process occurs whenever a large
-contiguous set of bytes are accessed, as might occur when reading or
-writing a FITS image.  In this case CFITSIO bypasses the internal IO
-buffers and simply reads or writes the desired bytes directly in the
-disk file with a single call to a low-level file read or write
-routine.  The minimum threshold for the number of bytes to read or
-write this way is set by the MINDIRECT parameter and is currently set
-to 3 FITS blocks = 8640 bytes.  This is the most efficient way to read
-or write large chunks of data and can achieve IO transfer rates of
-5 -- 10MB/s or greater.  Note that this fast direct IO process is not
-applicable when accessing columns of data in a FITS table because the
-bytes are generally not contiguous since they are interleaved by the
-other columns of data in the table.  This explains why the speed for
-accessing FITS tables is generally slower than accessing
-FITS images.
-
-Given this background information, the general strategy for efficiently
-accessing FITS files should be apparent:  when dealing with FITS
-images, read or write large chunks of data at a time so that the direct
-IO mechanism will be invoked;  when accessing FITS headers or FITS
-tables, on the other hand, once a particular FITS block has been
-loading into one of the IO buffers, try to access all the needed
-information in that block before it gets flushed out of the IO buffer.
-It is important to avoid the situation where the same FITS block is
-being read then flushed from a IO buffer multiple times.
-
-The following section gives more specific suggestions for optimizing
-the use of CFITSIO.
-
-**B.  Optimization Strategies
-
-1.  Because the data in FITS files is always stored in "big-endian" byte order,
-where the first byte of numeric values contains the most significant bits and the
-last byte contains the least significant bits, CFITSIO must swap the order of the bytes
-when reading or writing FITS files when running on little-endian machines (e.g., 
-Linux and Microsoft Windows operating systems running on PCs with x86 CPUs). 
-
-On fairly new CPUs that support "SSSE3" machine instructions 
-(e.g., starting with Intel Core 2 CPUs in 2007, and in AMD CPUs 
-beginning in 2011) significantly faster 4-byte and 8-byte swapping
-algorithms are available. These faster byte swapping functions are 
-not used by default in CFITSIO (because of the potential code 
-portablility issues), but users can enable them on supported 
-platforms by adding the appropriate compiler flags (-mssse3 with gcc
-or icc on linux) when compiling the swapproc.c source file, which will
-allow the compiler to generate code using the SSSE3 instruction set.
-A convenient way to do this is to configure the CFITSIO library
-with the following command:
--
-  >  ./configure --enable-ssse3
--
-Note, however, that a binary executable file that is 
-created using these faster functions will only run on 
-machines that support the SSSE3 machine instructions. It will
-crash on machines that do not support them.
-
-For faster 2-byte swaps on virtually all x86-64 CPUs (even those that
-do not support SSSE3), a variant using only SSE2 instructions exists.
-SSE2 is enabled by default on x86\_64 CPUs with 64-bit operating systems
-(and is also automatically enabled by the --enable-ssse3 flag).
-When running on x86\_64 CPUs with 32-bit operating systems, these faster 
-2-byte swapping algorithms are not used by default in CFITSIO, but can be 
-enabled explicitly with:
--
-./configure --enable-sse2
--
-Preliminary testing indicates that these SSSE3 and SSE2 based
-byte-swapping algorithms can boost the CFITSIO performance when 
-reading or writing FITS images by 20\% - 30\% or more.
-It is important to note, however, that compiler optimization must be
-turned on (e.g., by using the -O1 or -O2 flags in gcc) when building
-programs that use these fast byte-swapping algorithms in order
-to reap the full benefit of the SSSE3 and SSE2 instructions; without
-optimization, the code may actually run slower than when using
-more traditional byte-swapping techniques.
-
-2.  When dealing with a FITS primary array or IMAGE extension, it is
-more efficient to read or write large chunks of the  image at a time
-(at least 3 FITS blocks = 8640 bytes) so that the direct IO mechanism
-will be used as described in the previous section.  Smaller chunks of
-data are read or written via the IO buffers, which is somewhat less
-efficient because of the extra copy operation and additional
-bookkeeping steps that are required.  In principle it is more efficient
-to read or write as big an array of image pixels at one time as
-possible, however, if the array becomes so large that the operating
-system cannot store it all in RAM, then the performance may be degraded
-because of the increased swapping of virtual memory to disk.
-
-3.  When dealing with FITS tables, the most important efficiency factor
-in the software design is to read or write the data in the FITS file in
-a single pass through the file.  An example of poor program design
-would be to read a large, 3-column table by sequentially reading the
-entire first column, then going back to read the 2nd column, and
-finally the 3rd column; this obviously requires 3 passes through the
-file which could triple the execution time of an IO limited program.
-For small tables this is not important, but when reading multi-megabyte
-sized tables these inefficiencies can become significant.  The more
-efficient procedure in this case is to read or write only as many rows
-of the table as will fit into the available internal IO buffers, then
-access all the necessary columns of data within that range of rows.
-Then after the program is completely finished with the data in those
-rows it can move on to the next range of rows that will fit in the
-buffers, continuing in this way until the entire file has been
-processed.  By using this procedure of accessing all the columns of a
-table in parallel rather than sequentially, each block of the FITS file
-will only be read or written once.
-
-The optimal number of rows to read or write at one time in a given
-table depends on the width of the table row and on the number of IO
-buffers that have been allocated in CFITSIO.  The CFITSIO Iterator routine
-will automatically use the optimal-sized buffer, but there is also a
-CFITSIO routine that will return the optimal number of rows for a given
-table:  fits\_get\_rowsize.  It is not critical to use exactly the
-value of nrows returned by this routine, as long as one does not exceed
-it.  Using a very small value however can also lead to poor performance
-because of the overhead from the larger number of subroutine calls.
-
-The optimal number of rows returned by fits\_get\_rowsize is valid only
-as long as the application program is only reading or writing data in
-the specified table.  Any other calls to access data in the table
-header would  cause additional blocks of data
-to be loaded into the IO buffers displacing data from the original
-table, and should be avoided during the critical period while the table
-is being read or written.
-
-4.  Use the CFITSIO Iterator routine.  This routine provides a
-more `object oriented' way of reading and writing FITS files
-which automatically uses the most appropriate data buffer size 
-to achieve the maximum I/O throughput.  
-
-5.  Use binary table extensions rather than ASCII table
-extensions for better efficiency  when dealing with tabular data.  The
-I/O to ASCII tables is slower because of the overhead in formatting or
-parsing the ASCII data fields and because ASCII tables are about twice
-as large as binary tables that have the same information content.
-
-6. Design software so that it reads the FITS header keywords in the
-same order in which they occur in the file.  When reading keywords,
-CFITSIO searches forward starting from the position of the last keyword
-that was read.  If it reaches the end of the header without finding the
-keyword, it then goes back to the start of the header and continues the
-search down to the position where it started.  In practice, as long as
-the entire FITS header can fit at one time in the available internal IO
-buffers, then the header keyword access will be relatively fast and it makes
-little difference which order they are accessed.
-
-7. Avoid the use of scaling (by using the BSCALE and BZERO or TSCAL and
-TZERO keywords) in FITS files since the scaling operations add to the
-processing time needed to read or write the data.  In some cases it may
-be more efficient to temporarily turn off the scaling (using fits\_set\_bscale or
-fits\_set\_tscale) and then read or write the raw unscaled values in the FITS
-file.
-
-8. Avoid using the `implicit data type conversion' capability in
-CFITSIO.  For instance, when reading a FITS image with BITPIX = -32
-(32-bit floating point pixels), read the data into a single precision
-floating point data array in the program.  Forcing CFITSIO to convert
-the data to a different data type can slow the program.
-
-9. Where feasible, design FITS binary tables using vector column
-elements so that the data are written as a contiguous set of bytes,
-rather than as single elements in multiple rows.  For example, it is
-faster to access the data in a table that contains a single row
-and 2 columns with TFORM keywords equal to  '10000E' and '10000J', than
-it is to access the same amount of data in a table with 10000 rows
-which has columns with the TFORM keywords equal to '1E' and '1J'.  In
-the former case the 10000 floating point values in the first column are
-all written in a contiguous block of the file which can be read or
-written quickly, whereas in the second case each floating point value
-in the first column is interleaved with the integer value in the second
-column of the same row so CFITSIO has to explicitly move to the
-position of each element to be read or written.
-
-10. Avoid the use of variable length vector columns in binary tables,
-since any reading or writing of these data requires that CFITSIO first
-look up or compute the starting address of each row of data in the
-heap.  In practice, this is probably not a significant efficiency issue.
-
-11. When copying data from one FITS table to another, it is faster to
-transfer the raw bytes instead of reading then writing each column of
-the table.  The CFITSIO routines fits\_read\_tblbytes and
-fits\_write\_tblbytes will perform low-level reads or writes of any
-contiguous range of bytes in a table extension.  These routines can be
-used to read or write a whole row (or multiple rows  for even greater
-efficiency) of a table with a single function call.   These routines
-are fast because they bypass all the usual data scaling, error checking
-and machine dependent data conversion that is normally done by CFITSIO,
-and they allow the program to write the data to the output file in
-exactly the same byte order.  For these same reasons, these routines
-can corrupt the FITS data file if used incorrectly because no
-validation or machine dependent conversion is performed by these
-routines.  These routines are only recommended for optimizing critical
-pieces of code and should only be used by programmers who thoroughly
-understand the internal format of the FITS tables they are reading or
-writing.
-
-12. Another strategy for improving the speed of writing a FITS table,
-similar to the previous one, is to directly construct the entire byte
-stream for a whole table row (or multiple rows) within the application
-program and then write it to the FITS file with
-fits\_write\_tblbytes.  This avoids all the overhead normally present
-in the column-oriented CFITSIO write routines.  This technique should
-only be used for critical applications because it makes the code more
-difficult to understand and maintain, and it makes the code more system
-dependent (e.g., do the bytes need to be swapped before writing to the
-FITS file?).
-
-13.  Finally, external factors such as the speed of the data storage device,
-the size of the data cache, the amount of disk fragmentation, and the amount of
-RAM available on the system can all have a significant impact on
-overall I/O efficiency.  For critical applications, the entire hardware
-and software system should be reviewed to identify any
-potential I/O bottlenecks.

-*3   CFITSIO Error Status Codes
-
-The following table lists all the error status codes used by CFITSIO.
-Programmers are encouraged to use the symbolic mnemonics (defined in
-the file fitsio.h) rather than the actual integer status values to
-improve the readability of their code.

-\section{ A Brief Overview}
-
-CFITSIO is a machine-independent library of routines for reading and
-writing data files in the FITS (Flexible Image Transport System) data
-format.  It can also read IRAF format image files and raw binary data
-arrays by converting them on the fly into a virtual FITS format file.
-This library is written in ANSI C and provides a powerful yet simple
-interface for accessing FITS files which will run on most commonly used
-computers and workstations.  CFITSIO supports all the features
-described in the official NOST definition of the FITS format and can
-read and write all the currently defined types of extensions, including
-ASCII tables (TABLE), Binary tables (BINTABLE) and IMAGE extensions.
-The CFITSIO routines insulate the programmer from having to deal with
-the complicated formatting details in the FITS file, however, it is
-assumed that users have a general knowledge about the structure and
-usage of FITS files.
-
-CFITSIO also contains a set of Fortran callable wrapper routines which
-allow Fortran programs to call the CFITSIO routines.  See the companion
-``FITSIO User's Guide'' for the definition of the Fortran subroutine
-calling sequences.  These wrappers replace the older Fortran FITSIO
-library which is no longer supported.
-
-The CFITSIO package was initially developed by the HEASARC (High Energy
-Astrophysics Science Archive Research Center) at the NASA Goddard Space
-Flight Center to convert various existing and newly acquired
-astronomical data sets into FITS format and to further analyze data
-already in FITS format.  New features continue to be added to CFITSIO
-in large part due to contributions of ideas or actual code from
-users of the package.  The Integral Science Data Center in Switzerland,
-and the XMM/ESTEC project in The Netherlands made especially significant
-contributions that resulted in many of the new features that appeared
-in v2.0 of CFITSIO.
-

-\section{Sources of FITS Software and Information}
-
-The latest version of the CFITSIO source code,
-documentation, and example programs are available on the World-Wide
-Web or via anonymous ftp from:
-
-\begin{verbatim}
-        http://heasarc.gsfc.nasa.gov/fitsio
-        ftp://legacy.gsfc.nasa.gov/software/fitsio/c
-\end{verbatim}
-
-Any questions, bug reports, or suggested enhancements related to the CFITSIO
-package should be sent to the primary author:

-\end{verbatim}
-This User's Guide assumes that readers already have a general
-understanding of the definition and structure of FITS format files.
-Further information about FITS formats is available from the FITS Support
-Office at {\tt http://fits.gsfc.nasa.gov}.  In particular, the
-'NOST FITS Standard' gives the authoritative definition of the FITS data
-format, and the  `FITS User's Guide' provides additional historical background
-and practical advice on using FITS files.
-
-The HEASARC also provides a very sophisticated FITS file analysis
-program called `Fv' which can be used to display and edit the contents
-of any FITS file as well as construct new FITS files from scratch. The
-display functions in Fv allow users to interactively adjust the
-brightness and contrast of images, pan, zoom, and blink images, and
-measure the positions and brightnesses of objects within images. FITS
-tables can be displayed like a spread sheet, and then modified using
-powerful calculator and sorting functions.  Fv is freely available for
-most Unix platforms, Mac PCs, and Windows PCs.
-CFITSIO users may also be interested in the FTOOLS package of programs
-that can be used to manipulate and analyze FITS format files.
-Fv and FTOOLS are available from their respective Web sites at:

-\section{Acknowledgments}
-
-The development of the many powerful features in CFITSIO was made
-possible through collaborations with many people or organizations from
-around the world.  The following in particular have made especially
-significant contributions:
-
-Programmers from the Integral Science Data Center, Switzerland (namely,
-Jurek Borkowski, Bruce O'Neel, and Don Jennings), designed the concept
-for the plug-in I/O drivers that was introduced with CFITSIO 2.0.  The
-use of `drivers' greatly simplified  the low-level I/O, which in turn
-made other new features in CFITSIO (e.g., support for compressed FITS
-files and support for IRAF format image files) much easier to
-implement.  Jurek Borkowski wrote the Shared Memory driver, and Bruce
-O'Neel wrote the drivers for accessing FITS files over the network
-using the FTP, HTTP, and ROOT protocols.  Also, in 2009, Bruce O'Neel
-was the key developer of the thread-safe version of CFITSIO.
-
-The ISDC also provided the template parsing routines (written by Jurek
-Borkowski) and the hierarchical grouping routines (written by Don
-Jennings).  The ISDC DAL (Data Access Layer) routines are layered on
-top of CFITSIO and make extensive use of these features.
-
-Giuliano Taffoni and Andrea Barisani, at INAF, University of Trieste,
-Italy, implemented the I/O driver routines for accessing FITS files
-on the computational grids using the gridftp protocol.
-
-Uwe Lammers (XMM/ESA/ESTEC, The Netherlands) designed the
-high-performance lexical parsing algorithm that is used to do
-on-the-fly filtering of FITS tables.  This algorithm essentially
-pre-compiles the user-supplied selection expression into a form that
-can be rapidly evaluated for each row.  Peter Wilson (RSTX, NASA/GSFC)
-then wrote the parsing routines used by CFITSIO based on Lammers'
-design, combined with other techniques such as the CFITSIO iterator
-routine to further enhance the data processing throughput.  This effort
-also benefited from a much earlier lexical parsing routine that was
-developed by Kent Blackburn (NASA/GSFC). More recently, Craig Markwardt
-(NASA/GSFC) implemented additional functions (median, average, stddev)
-and other enhancements to the lexical parser.
-
-The CFITSIO iterator function is loosely based on similar ideas
-developed for the XMM Data Access Layer.
-
-Peter Wilson (RSTX, NASA/GSFC) wrote the complete set of
-Fortran-callable wrappers for all the CFITSIO routines, which in turn
-rely on the CFORTRAN macro developed by Burkhard Burow.
-
-The syntax used by CFITSIO for filtering or binning input FITS files is
-based on ideas developed for the AXAF Science Center Data Model by
-Jonathan McDowell, Antonella Fruscione, Aneta Siemiginowska and Bill
-Joye. See http://heasarc.gsfc.nasa.gov/docs/journal/axaf7.html for
-further description of the AXAF Data Model.
-
-The file decompression code were taken directly from the gzip (GNU zip)
-program developed by Jean-loup Gailly and others.
-
-The new compressed image data format (where the image is tiled and
-the compressed byte stream from each tile is stored in a binary table)
-was implemented in collaboration with Richard White (STScI), Perry
-Greenfield (STScI) and Doug Tody (NOAO).
-
-Doug Mink (SAO) provided the routines for converting IRAF format
-images into FITS format.
-
-Martin Reinecke (Max Planck Institute, Garching)) provided the modifications to
-cfortran.h that are necessary to support 64-bit integer values when calling
-C routines from fortran programs.  The cfortran.h macros were originally developed
-by Burkhard Burow (CERN).
-
-Julian Taylor (ESO, Garching) provided the fast byte-swapping algorithms
-that use the SSE2 and SSSE3 machine instructions available on x86\_64 CPUs.
-
-In addition, many other people have made valuable contributions to the
-development of CFITSIO.  These include (with apologies to others that may
-have inadvertently been omitted):

- >  make install  (this step is optional)
-\end{verbatim}
-at the operating system prompt.  The configure command customizes the
-Makefile for the particular system, then the `make' command compiles the
-source files and builds the library.  Type `./configure' and not simply
-`configure' to ensure that the configure script in the current directory
-is run and not some other system-wide configure script.  The optional
-'prefix' argument to configure gives the path to the directory where
-the CFITSIO library and include files should be installed via the later
-'make install' command. For example,
-
-\begin{verbatim}
-   > ./configure --prefix=/usr1/local
-\end{verbatim}
-will cause the 'make install' command to copy the CFITSIO libcfitsio file
-to /usr1/local/lib and the necessary include files to /usr1/local/include
-(assuming of course that the  process has permission to write to these
-directories).
-
-The optional --enable-reentrant flag will attempt to configure CFITSIO
-so that it can be used in multi-threaded programs.  See the "Using CFITSIO in Multi-threaded Environments" section, below, for more
-
-The optional --enable-sse2 and --enable-ssse3 flags will cause configure to
-attempt to build CFITSIO using faster byte-swapping algorithms.
-See the "Optimizing Programs" chapter of this manual for
-more information about these options.
-
-The 'make shared' option builds a shared or dynamic version of the
-CFITSIO library.  When using the shared library the executable code is
-not copied into your program at link time and instead the program
-locates the necessary library code at run time, normally through
-LD\_LIBRARY\_PATH or some other method. The advantages of using a shared
-library are:
-
-\begin{verbatim}
-   1.  Less disk space if you build more than 1 program
-   2.  Less memory if more than one copy of a program using the shared
-       library is running at the same time since the system is smart
-       enough to share copies of the shared library at run time.
-   3.  Possibly easier maintenance since a new version of the shared
-       library can be installed without relinking all the software
-       that uses it (as long as the subroutine names and calling
-       sequences remain unchanged).
-   4.  No run-time penalty.
-\end{verbatim}
-The disadvantages are:
-
-\begin{verbatim}
-   1. More hassle at runtime.  You have to either build the programs
-      specially or have LD_LIBRARY_PATH set right.
-   2. There may be a slight start up penalty, depending on where you are
-      reading the shared library and the program from and if your CPU is
-      either really slow or really heavily loaded.
-\end{verbatim}
-
-On Mac OS X platforms the 'make shared' command works like on other
-UNIX platforms, but a .dylib file will be created instead of .so.  If
-installed in a nonstandard location, add its location to the
-DYLD\_LIBRARY\_PATH environment variable so that the library can be found
-at run time.
-
-On HP/UX systems, the environment variable CFLAGS should be set
-to -Ae before running configure to enable "extended ANSI" features.
-
-By default, a set of Fortran-callable wrapper routines are
-also built and included in the CFITSIO library.  If these wrapper
-routines are not needed (i.e., the CFITSIO library will not
-be linked to any Fortran applications which call FITSIO subroutines)
-then they may be omitted from the build by typing 'make all-nofitsio'
-instead of simply typing 'make'.  This will reduce the size
-of the CFITSIO library slightly.
-
-It may not be possible to statically link programs that use CFITSIO on
-some platforms (namely, on Solaris 2.6) due to the network drivers
-(which provide FTP and HTTP access to FITS files).  It is possible to
-make both a dynamic and a static version of the CFITSIO library, but
-network file access will not be possible using the static version.
-
-
-\subsection{VMS}
-
-On VAX/VMS and ALPHA/VMS systems the make\_gfloat.com command file may
-be executed to build the cfitsio.olb object library using the default
-G-floating point option for double variables.  The make\_dfloat.com and
-make\_ieee.com files may be used instead to build the library with the
-other floating point options. Note that the getcwd function that is
-used in the group.c module may require that programs using CFITSIO be
-linked with the ALPHA\$LIBRARY:VAXCRTL.OLB library.  See the example
-link line in the next section of this document.
-
-
-\subsection{Windows PCs}
-
-A precompiled DLL version of CFITSIO is available for IBM-PC users of
-the Borland or Microsoft Visual C++ compilers in the files
-cfitsiodll\_3xxx\_borland.zip and cfitsiodll\_3xxx\_vcc.zip, where
-'3xxx' represents the current release number.  These zip archives also
-contains other files and instructions on how to use the CFITSIO DLL
-library.
-
-The CFITSIO library may also be built from the source code using the
-makefile.bc or makefile.vcc  files.  Finally, the makepc.bat file gives
-an example of  building CFITSIO with the Borland C++ v4.5 or v5.5  compiler
-using older DOS commands.
-
-
-\subsection{Macintosh PCs}
-
-When building on Mac OS-X, users should follow the Unix instructions,
-above.  See the README.MacOS file for instructions on building a Universal
-Binary that supports both Intel and PowerPC CPUs.
-
-
-\section{Testing the Library}
-
-The CFITSIO library should be tested by building and running
-the testprog.c program that is included with the release.
-On Unix systems, type:
-
-\begin{verbatim}
-    % make testprog
-    % testprog > testprog.lis
-    % diff testprog.lis testprog.out
-    % cmp testprog.fit testprog.std
-\end{verbatim}
- On VMS systems,
-(assuming cc is the name of the C compiler command), type:
-
-\begin{verbatim}
-    $ cc testprog.c
-    $ link testprog, cfitsio/lib, alpha$library:vaxcrtl/lib
-    $ run testprog
-\end{verbatim}
-The test program should produce a FITS file called `testprog.fit'
-that is identical to the `testprog.std' FITS file included with this
-release.  The diagnostic messages (which were piped to the file
-testprog.lis in the Unix example) should be identical to the listing
-contained in the file testprog.out.  The 'diff' and 'cmp' commands
-shown above should not report any differences in the files.  (There
-may be some minor format differences, such as the presence or
-absence of leading zeros, or 3 digit exponents in numbers,
-which can be ignored).
-
-The Fortran wrappers in CFITSIO may be tested with the testf77
-program on Unix systems with:
-
-\begin{verbatim}
-    % f77 -o testf77 testf77.f -L. -lcfitsio -lnsl -lsocket
-  or
-    % f77 -f -o testf77 testf77.f -L. -lcfitsio    (under SUN O/S)
-  or
-    % f77 -o testf77 testf77.f -Wl,-L. -lcfitsio -lm -lnsl -lsocket (HP/UX)
-
-    % testf77 > testf77.lis
-    % diff testf77.lis testf77.out
-    % cmp testf77.fit testf77.std
-\end{verbatim}
-On machines running SUN O/S, Fortran programs must be compiled with the
-'-f' option to force double precision variables to be aligned on 8-byte
-boundarys to make the fortran-declared variables compatible with C.  A
-similar compiler option may be required on other platforms.  Failing to
-use this option may cause the program to crash on FITSIO routines that
-read or write double precision variables.
-
-Also note that on some systems, the output listing of the testf77
-program may differ slightly from the testf77.std template, if leading
-zeros are not printed by default before the decimal point when using F
-format.
-
-A few other utility programs are included with CFITSIO; the first four
-of this programs can be compiled an linked by typing `make
-program\_name' where `program\_name' is the actual name of the program:
-
-\begin{verbatim}
-    speed - measures the maximum throughput (in MB per second)
-              for writing and reading FITS files with CFITSIO.
-
-    listhead - lists all the header keywords in any FITS file
-
-    fitscopy - copies any FITS file (especially useful in conjunction
-                 with the CFITSIO's extended input filename syntax).
-
-    cookbook - a sample program that performs common read and
-                 write operations on a FITS file.
-
-    iter_a, iter_b, iter_c - examples of the CFITSIO iterator routine
-\end{verbatim}
-
-
-\section{Linking Programs with CFITSIO}
-
-When linking applications software with the CFITSIO library, several
-system libraries usually need to be specified on the link command
-line.  On Unix systems, the most reliable way to determine what
-libraries are required is to type 'make testprog' and see what
-libraries the configure script has added.  The typical libraries that
-need to be added are -lm (the math library) and -lnsl and -lsocket
-(needed only for FTP and HTTP file access).  These latter 2 libraries
-are not needed on VMS and Windows platforms, because FTP file access is
-not currently supported on those platforms.
-
-Note that when upgrading to a newer version of CFITSIO it is usually
-necessary to recompile, as well as relink, the programs that use CFITSIO,
-because the definitions in fitsio.h often change.
-
-
-\section{Using CFITSIO in Multi-threaded Environments}
-
-CFITSIO can be used either with the
-POSIX pthreads interface or the OpenMP interface for multi-threaded
-parallel programs.  When used in a multi-threaded environment,
-the CFITSIO library *must* be built using
-the -D\_REENTRANT compiler directive.  This can be done using the following
-build commands:
-
-\begin{verbatim}
-  >./configure --enable-reentrant
-  > make
-\end{verbatim}
-A function called fits\_is\_reentrant is available to test
-whether or not CFITSIO was compiled with the -D\_REENTRANT
-directive.  When this feature is enabled, multiple threads can
-call any of the CFITSIO routines
-to simultaneously read or write separate
-FITS files.  Multiple threads can also read data from
-the same FITS file simultaneously, as long as the file
-was opened independently by each thread.  This relies on
-the operating system to correctly deal with reading the
-same file by multiple processes.  Different threads should
-not share the same 'fitsfile' pointer to read an opened
-FITS file, unless locks are placed around the calls to
-the CFITSIO reading routines.
-Different threads should never try to write to the same
-FITS file.
-
-
-\section{Getting Started with CFITSIO}
-
-In order to effectively use the CFITSIO library it is recommended that
-new users begin by reading the ``CFITSIO Quick Start Guide''.  It
-contains all the basic information needed to write programs that
-perform most types of operations on FITS files.  The set of example
-FITS utility programs that are available from the CFITSIO web site are
-also very useful for learning how to use CFITSIO.  To learn even more
-about the capabilities of the CFITSIO library the following steps are
-recommended:
-
-1.  Read the following short `FITS Primer' chapter for an overview of
-the structure of FITS files.
-
-2. Review the Programming Guidelines in Chapter 4 to become familiar
-with the conventions used by the CFITSIO interface.
-
-3.  Refer to the cookbook.c, listhead.c, and fitscopy.c programs that
-are included with this release for examples of routines that perform
-various common FITS file operations.  Type 'make program\_name' to
-compile and link these programs on Unix systems.
-
-4.  Write a simple program to read or write a FITS file using the Basic
-Interface routines described in Chapter 5.
-
-5.  Scan through the more specialized routines that are described in
-the following chapters to become familiar with the functionality that
-they provide.
-
-
-\section{Example Program}
-
-The following listing shows an example of how to use the CFITSIO
-routines in a C program.    Refer to the cookbook.c program that is
-included with the CFITSIO distribution for other example routines.
-
-This program creates a new FITS file, containing a FITS image.  An
-`EXPOSURE' keyword is written to the header, then the image data are
-written to the FITS file before closing the FITS file.
-
-\begin{verbatim}
-#include "fitsio.h"  /* required by every program that uses CFITSIO  */
-main()
-{
-    fitsfile *fptr;       /* pointer to the FITS file; defined in fitsio.h */
-    int status, ii, jj;
-    long  fpixel = 1, naxis = 2, nelements, exposure;
-    long naxes[2] = { 300, 200 };   /* image is 300 pixels wide by 200 rows */
-    short array[200][300];
-
-    status = 0;         /* initialize status before calling fitsio routines */
-    fits_create_file(&fptr, "testfile.fits", &status);   /* create new file */
-
-    /* Create the primary array image (16-bit short integer pixels */
-    fits_create_img(fptr, SHORT_IMG, naxis, naxes, &status);
-
-    /* Write a keyword; must pass the ADDRESS of the value */
-    exposure = 1500.;
-    fits_update_key(fptr, TLONG, "EXPOSURE", &exposure,
-         "Total Exposure Time", &status);
-
-    /* Initialize the values in the image with a linear ramp function */
-    for (jj = 0; jj < naxes[1]; jj++)
-        for (ii = 0; ii < naxes[0]; ii++)
-            array[jj][ii] = ii + jj;
-
-    nelements = naxes[0] * naxes[1];          /* number of pixels to write */
-
-    /* Write the array of integers to the image */
-    fits_write_img(fptr, TSHORT, fpixel, nelements, array[0], &status);
-
-    fits_close_file(fptr, &status);            /* close the file */
-
-    fits_report_error(stderr, status);  /* print out any error messages */
-    return( status );

-\chapter{  A FITS Primer }
-
-This section gives a brief overview of the structure of FITS files.
-Users should refer to the documentation available from the NOST, as
-described in the introduction, for more detailed information on FITS
-formats.
-
-FITS was first developed in the late 1970's as a standard data
-interchange format between various astronomical observatories.  Since
-then FITS has become the standard data format supported by most
-astronomical data analysis software packages.
-
-A FITS file consists of one or more Header + Data Units (HDUs), where
-the first HDU is called the `Primary HDU', or `Primary Array'.  The
-primary array contains an N-dimensional array of pixels, such as a 1-D
-spectrum, a 2-D image, or a 3-D data cube.  Six different primary
-data types are supported: Unsigned 8-bit bytes, 16-bit, 32-bit, and 64-bit signed
-integers, and 32 and 64-bit floating point reals.  FITS also has a
-convention for storing 16 and 32-bit unsigned integers (see the later
-section entitled `Unsigned Integers' for more details). The primary HDU
-may also consist of only a header with a null array containing no
-data pixels.
-
-Any number of additional HDUs may follow the primary array; these
-additional HDUs are called FITS `extensions'.  There are currently 3
-types of extensions defined by the FITS standard:
-
-\begin{itemize}
-\item
-  Image Extension - a N-dimensional array of pixels, like in a primary array
-\item
-  ASCII Table Extension - rows and columns of data in ASCII character format
-\item
-  Binary Table Extension - rows and columns of data in binary representation
-\end{itemize}
-
-In each case the HDU consists of an ASCII Header Unit followed by an optional
-Data Unit.  For historical reasons, each Header or Data unit must be an
-exact multiple of 2880 8-bit bytes long.  Any unused space is padded
-with fill characters (ASCII blanks or zeros).
-
-Each Header Unit consists of any number of 80-character keyword records
-or `card images' which have the
-general form:
-
-\begin{verbatim}
-  KEYNAME = value / comment string
-  NULLKEY =       / comment: This keyword has no value
-\end{verbatim}
-The keyword names may be up to 8 characters long and can only contain
-uppercase letters, the digits 0-9, the hyphen, and the underscore
-character. The keyword name is (usually) followed by an equals sign and
-a space character (= ) in columns 9 - 10 of the record, followed by the
-value of the keyword which may be either an integer, a floating point
-number, a character string (enclosed in single quotes), or a boolean
-value (the letter T or F).   A keyword may also have a null or undefined
-value if there is no specified value string, as in the second example, above
-
-The last keyword in the header is always the `END' keyword which has no
-value or comment fields. There are many rules governing the exact
-format of a keyword record (see the NOST FITS Standard) so it is better
-to rely on standard interface software like CFITSIO to correctly
-construct or to parse the keyword records rather than try to deal
-directly with the raw FITS formats.
-
-Each Header Unit begins with a series of required keywords which depend
-on the type of HDU.  These required keywords specify the size and
-format of the following Data Unit.  The header may contain other
-optional keywords to describe other aspects of the data, such as the
-units or scaling values.  Other COMMENT or HISTORY keywords are also
-frequently added to further document the data file.
-
-The optional Data Unit immediately follows the last 2880-byte block in
-the Header Unit.  Some HDUs do not have a Data Unit and only consist of
-the Header Unit.
-
-If there is more than one HDU in the FITS file, then the Header Unit of
-the next HDU immediately follows the last 2880-byte block of the
-previous Data Unit (or Header Unit if there is no Data Unit).
-
-The main required keywords in FITS primary arrays or image extensions are:
-\begin{itemize}
-\item
-BITPIX -- defines the data type of the array: 8, 16, 32, 64, -32, -64 for
-unsigned 8--bit byte, 16--bit signed integer, 32--bit signed integer,
-32--bit IEEE floating point, and 64--bit IEEE double precision floating
-point, respectively.
-\item
-NAXIS --  the number of dimensions in the array, usually 0, 1, 2, 3, or 4.
-\item
-NAXISn -- (n ranges from 1 to NAXIS) defines the size of each dimension.
-\end{itemize}
-
-FITS tables start with the keyword XTENSION = `TABLE' (for ASCII
-tables) or XTENSION = `BINTABLE' (for binary tables) and have the
-following main keywords:
-\begin{itemize}
-\item
-TFIELDS -- number of fields or columns in the table
-\item
-NAXIS2 -- number of rows in the table
-\item
-TTYPEn -- for each column (n ranges from 1 to TFIELDS) gives the
-name of the column
-\item
-TFORMn -- the data type of the column
-\item
-TUNITn -- the physical units of the column (optional)
-\end{itemize}
-
-Users should refer to the FITS Support Office at {\tt http://fits.gsfc.nasa.gov}
-for further information about the FITS format and related software
-packages.

-\chapter{ Programming Guidelines }
-
-
-\section{CFITSIO Definitions}
-
-Any program that uses the CFITSIO interface must include the fitsio.h
-header file with the statement
-
-\begin{verbatim}
-  #include "fitsio.h"
-\end{verbatim}
-This header file contains the prototypes for all the CFITSIO user
-interface routines as well as the definitions of various constants used
-in the interface.  It also defines a C structure of type `fitsfile'
-that is used by CFITSIO to store the relevant parameters that define
-the format of a particular FITS file.  Application programs must define
-a pointer to this structure for each FITS file that is to be opened.
-This structure is initialized (i.e., memory is allocated for the
-structure) when the FITS file is first opened or created with the
-fits\_open\_file or fits\_create\_file routines.  This fitsfile pointer
-is then passed as the first argument to every other CFITSIO routine
-that operates on the FITS file.  Application programs must not directly
-read or write elements in this fitsfile structure because the
-definition of the structure may change in future versions of CFITSIO.
-
-A number of symbolic constants are also defined in fitsio.h for the
-convenience of application programmers.  Use of these symbolic
-constants rather than the actual numeric value will help to make the
-source code more readable and easier for others to understand.
-
-\begin{verbatim}
-String Lengths, for use when allocating character arrays:
-
-  #define FLEN_FILENAME 1025 /* max length of a filename                  */
-  #define FLEN_KEYWORD   72  /* max length of a keyword                   */
-  #define FLEN_CARD      81  /* max length of a FITS header card          */
-  #define FLEN_VALUE     71  /* max length of a keyword value string      */
-  #define FLEN_COMMENT   73  /* max length of a keyword comment string    */
-  #define FLEN_ERRMSG    81  /* max length of a CFITSIO error message     */
-  #define FLEN_STATUS    31  /* max length of a CFITSIO status text string */
-
-  Note that FLEN_KEYWORD is longer than the nominal 8-character keyword
-  name length because the HIERARCH convention supports longer keyword names.
-
-Access modes when opening a FITS file:
-
-  #define READONLY  0
-  #define READWRITE 1
-
-BITPIX data type code values for FITS images:
-
-  #define BYTE_IMG      8  /*  8-bit unsigned integers */
-  #define SHORT_IMG    16  /* 16-bit   signed integers */
-  #define LONG_IMG     32  /* 32-bit   signed integers */
-  #define LONGLONG_IMG 64  /* 64-bit   signed integers */
-  #define FLOAT_IMG   -32  /* 32-bit single precision floating point */
-  #define DOUBLE_IMG  -64  /* 64-bit double precision floating point */
-
-  The following 4 data type codes are also supported by CFITSIO:
-  #define SBYTE_IMG  10   /*  8-bit signed integers, equivalent to */
-                          /*  BITPIX = 8, BSCALE = 1, BZERO = -128 */
-  #define USHORT_IMG  20  /* 16-bit unsigned integers, equivalent to */
-                          /*  BITPIX = 16, BSCALE = 1, BZERO = 32768 */
-  #define ULONG_IMG   40  /* 32-bit unsigned integers, equivalent to */
-                          /*  BITPIX = 32, BSCALE = 1, BZERO = 2147483648 */
-
-Codes for the data type of binary table columns and/or for the
-data type of variables when reading or writing keywords or data:
-
-                              DATATYPE               TFORM CODE
-  #define TBIT          1  /*                            'X' */
-  #define TBYTE        11  /* 8-bit unsigned byte,       'B' */
-  #define TLOGICAL     14  /* logicals (int for keywords     */
-                           /*  and char for table cols   'L' */
-  #define TSTRING      16  /* ASCII string,              'A' */
-  #define TSHORT       21  /* signed short,              'I' */
-  #define TLONG        41  /* signed long,                   */
-  #define TLONGLONG    81  /* 64-bit long signed integer 'K' */
-  #define TFLOAT       42  /* single precision float,    'E' */
-  #define TDOUBLE      82  /* double precision float,    'D' */
-  #define TCOMPLEX     83  /* complex (pair of floats)   'C' */
-  #define TDBLCOMPLEX 163  /* double complex (2 doubles) 'M' */
-
-  The following data type codes are also supported by CFITSIO:
-  #define TINT         31  /* int                            */
-  #define TSBYTE       12  /* 8-bit signed byte,         'S' */
-  #define TUINT        30  /* unsigned int               'V' */
-  #define TUSHORT      20  /* unsigned short             'U'  */
-  #define TULONG       40  /* unsigned long                  */
-
-  The following data type code is only for use with fits\_get\_coltype
-  #define TINT32BIT    41  /* signed 32-bit int,         'J' */
-
-
-HDU type code values (value returned when moving to new HDU):
-
-  #define IMAGE_HDU  0  /* Primary Array or IMAGE HDU */
-  #define ASCII_TBL  1  /* ASCII  table HDU */
-  #define BINARY_TBL 2  /* Binary table HDU */
-  #define ANY_HDU   -1  /* matches any type of HDU */
-
-Column name and string matching case-sensitivity:
-
-  #define CASESEN   1   /* do case-sensitive string match */
-  #define CASEINSEN 0   /* do case-insensitive string match */
-
-Logical states (if TRUE and FALSE are not already defined):
-
-  #define TRUE 1
-  #define FALSE 0
-
-Values to represent undefined floating point numbers:
-
-  #define FLOATNULLVALUE  -9.11912E-36F
-  #define DOUBLENULLVALUE -9.1191291391491E-36
-
-Image compression algorithm definitions
-
-  #define RICE_1       11
-  #define GZIP_1       21

-The concept of the Current Header and Data Unit, or CHDU, is
-fundamental to the use of the CFITSIO library.  A simple FITS image may
-only contain a single Header and Data unit (HDU), but in general FITS
-files can contain multiple Header Data Units (also known as
-`extensions'), concatenated one after the other in the file.  The user
-can specify which HDU should be initially opened at run time by giving
-the HDU name or number after the root file name.  For example,
-'myfile.fits[4]' opens the 5th HDU in the file (note that the numbering
-starts with 0), and 'myfile.fits[EVENTS] opens the HDU with the name
-'EVENTS' (as defined by the EXTNAME or HDUNAME keywords).  If no HDU is
-specified then CFITSIO opens the first HDU (the primary array) by
-default.  The CFITSIO routines which read and write data  only operate
-within the opened HDU,  Other CFITSIO routines are provided to move to
-and open any other existing HDU within the FITS file or to append or
-insert new HDUs in the FITS file.
-
-
-\section{Function Names and Variable Datatypes}
-
-Most of the CFITSIO routines have both a short name as well as a
-longer descriptive name.  The short name is only 5 or 6 characters long
-and is similar to the subroutine name in the Fortran-77 version of
-FITSIO.  The longer name is more descriptive and it is recommended that
-it be used instead of the short name to more clearly document the
-source code.
-
-Many of the CFITSIO routines come in families which differ only in the
-data type of the associated parameter(s).  The data type of these
-routines is indicated by the suffix of the routine name.  The short
-routine names have a 1 or 2 character suffix (e.g., 'j' in 'ffpkyj')
-while the long routine names have a 4 character or longer suffix
-as shown in the following table:
-
-\begin{verbatim}
-    Long      Short  Data
-    Names     Names  Type
-    -----     -----  ----
-    _bit        x    bit
-    _byt        b    unsigned byte
-    _sbyt       sb   signed byte
-    _sht        i    short integer
-    _lng        j    long integer
-    _lnglng     jj   8-byte LONGLONG integer (see note below)
-    _usht       ui   unsigned short integer
-    _ulng       uj   unsigned long integer
-    _uint       uk   unsigned int integer
-    _int        k    int integer
-    _flt        e    real exponential floating point (float)
-    _fixflt     f    real fixed-decimal format floating point (float)
-    _dbl        d    double precision real floating-point (double)
-    _fixdbl     g    double precision fixed-format floating point (double)
-    _cmp        c    complex reals (pairs of float values)
-    _fixcmp     fc   complex reals, fixed-format floating point
-    _dblcmp     m    double precision complex (pairs of double values)
-    _fixdblcmp  fm   double precision complex, fixed-format floating point
-    _log        l    logical (int)
-    _str        s    character string
-\end{verbatim}
-
-The logical data type corresponds to `int' for logical keyword values,
-and `byte' for logical binary table columns.  In other words, the value
-when writing a logical keyword must be stored in an `int' variable, and
-must be stored in a `char' array when reading or writing to `L' columns
-in a binary table.  Implicit data type conversion is not supported for
-logical table columns, but is for keywords, so a logical keyword may be
-read and cast to any numerical data type; a returned value = 0
-indicates false, and any other value = true.
-
-The `int' data type may be 2 bytes long on some old PC compilers,
-but otherwise it is nearly always 4 bytes long.   Some 64-bit
-machines, like the Alpha/OSF, define the `short', `int',
-and `long' integer data types to be 2, 4, and 8 bytes long,
-respectively.
-
-Because there is no universal C compiler standard for the name of the
-8-byte integer datatype, the fitsio.h include file typedef's
-'LONGLONG'  to be equivalent to  an
-appropriate 8-byte integer data type on each supported platform.
-For maximum software portability it is recommended that
-this LONGLONG datatype be used to define 8-byte integer variables
-rather than using the native data type name on a particular
-platform. On most
-32-bit Unix and Mac OS-X operating systems LONGLONG is equivalent to the
-intrinsic 'long long' 8-byte integer datatype.  On 64-bit systems (which currently
-includes Alpha OSF/1, 64-bit Sun Solaris, 64-bit SGI MIPS, and  64-bit
-Itanium and Opteron PC systems), LONGLONG is  simply typedef'ed to be
-equivalent to 'long'.   Microsoft Visual C++ Version 6.0 does not define
-a 'long long'  data type, so LONGLONG is typedef'ed to be equivalent to
-the '\_\_int64' data type on 32-bit windows systems when using Visual C++.
-
-A related issue that affects the portability of software is how to print
-out the value of a 'LONGLONG' variable with printf.  Developers may
-find it convenient to use the following preprocessing statements
-in their C programs to handle this in a machine-portable manner:
-
-
-\begin{verbatim}
-#if defined(_MSC_VER) /* Microsoft Visual C++ */
-          printf("%I64d", longlongvalue);
-	
-#elif (USE_LL_SUFFIX == 1)
-          printf("%lld", longlongvalue);
-	
-#else
-          printf("%ld", longlongvalue);
-#endif
-\end{verbatim}
-
-Similarly, the name of the C utility routine that converts a character
-string of digits into a 8-byte integer value is platform dependent:
-
-
-\begin{verbatim}
-#if defined(_MSC_VER) /* Microsoft Visual C++ */
-      /* VC++ 6.0 does not seem to have an 8-byte conversion routine */
-	
-#elif (USE_LL_SUFFIX == 1)
-          longlongvalue = atoll(*string);
-	
-#else
-          longlongvalue = atol(*string);
-#endif
-\end{verbatim}
-
-When dealing with the FITS byte data type it is important to remember
-that the raw values (before any scaling by the BSCALE and BZERO, or
-TSCALn and TZEROn keyword values) in byte arrays (BITPIX = 8) or byte
-columns (TFORMn = 'B') are interpreted as unsigned bytes with values
-ranging from 0 to 255.  Some C compilers define a 'char' variable as
-signed, so it is important to explicitly declare a numeric char
-variable as 'unsigned char' to avoid any ambiguity
-
-One feature of the CFITSIO routines is that they can operate on a `X'
-(bit) column in a binary table as though it were a `B' (byte) column.
-For example a `11X' data type column can be interpreted the same as a
-`2B' column (i.e., 2 unsigned 8-bit bytes).  In some instances, it can
-be more efficient to read and write whole bytes at a time, rather than
-reading or writing each individual bit.
-
-The complex and double precision complex data types are not directly
-supported in ANSI C so these data types should be interpreted as pairs
-of float or double values, respectively, where the first  value in each
-pair is the real part, and the second is the imaginary part.
-
-
-\section{Support for Unsigned Integers and Signed Bytes}
-
-Although FITS does not directly support unsigned integers as one of its
-fundamental data types, FITS can still be used to efficiently store
-unsigned integer data values in images and binary tables.  The
-convention used in FITS files is to store the unsigned integers as
-signed integers with an associated offset (specified by the BZERO or
-TZEROn keyword).  For example, to store unsigned 16-bit integer values
-in a FITS image the image would be defined as a signed 16-bit integer
-(with BITPIX keyword = SHORT\_IMG = 16) with the keywords BSCALE = 1.0
-and BZERO = 32768.  Thus the unsigned values of 0, 32768, and 65535,
-for example, are physically stored in the FITS image as -32768, 0, and
-32767, respectively;  CFITSIO automatically adds the BZERO offset to
-these values when they are read.  Similarly, in the case of unsigned
-32-bit integers the BITPIX keyword would be equal to LONG\_IMG = 32 and
-BZERO would be equal to 2147483648 (i.e. 2 raised to the 31st power).
-
-The CFITSIO interface routines will efficiently and transparently apply
-the appropriate offset in these cases so in general application
-programs do not need to be concerned with how the unsigned values are
-actually stored in the FITS file.  As a convenience for users, CFITSIO
-has several predefined constants for the value of BITPIX  (USHORT\_IMG,
-ULONG\_IMG) and for the TFORMn value in the case of binary tables (`U'
-and `V') which programmers can use when creating FITS files containing
-unsigned integer values.  The following code fragment illustrates how
-to write a FITS 1-D primary array of unsigned 16-bit integers:
-
-\begin{verbatim}
-      unsigned short uarray[100];
-      int naxis, status;
-      long naxes[10], group, firstelem, nelements;
-       ...
-      status = 0;
-      naxis = 1;
-      naxes[0] = 100;
-      fits_create_img(fptr, USHORT_IMG, naxis, naxes, &status);
-
-      firstelem = 1;
-      nelements = 100;
-      fits_write_img(fptr, TUSHORT, firstelem, nelements,
-                          uarray, &status);
-       ...
-\end{verbatim}
-In the above example, the 2nd parameter in fits\_create\_img tells
-CFITSIO to write the header keywords appropriate for an array of 16-bit
-unsigned integers (i.e., BITPIX = 16 and BZERO = 32768).  Then the
-fits\_write\_img routine writes the array of unsigned short integers
-(uarray) into the primary array of the FITS file.  Similarly, a 32-bit
-unsigned integer image may be created by setting the second parameter
-in fits\_create\_img equal to `ULONG\_IMG' and by calling the
-fits\_write\_img routine with the second parameter = TULONG to write
-the array of unsigned long image pixel values.
-
-An analogous set of routines are available for reading or writing unsigned
-integer values and signed byte values in a FITS binary table extension.
-When specifying the TFORMn keyword value which defines the format of a
-column, CFITSIO recognized 3 additional data type codes besides those
-already defined in the FITS standard: `U' meaning a 16-bit unsigned
-integer column, `V' for a 32-bit unsigned integer column, and 'S'
-for a signed byte column.  These non-standard data type codes are not
-actually written into the FITS file but instead are just used internally
-within CFITSIO.  The following code fragment illustrates how to use
-these features:
-
-\begin{verbatim}
-      unsigned short uarray[100];
-      unsigned int  varray[100];
-
-      int colnum, tfields, status;
-      long nrows, firstrow, firstelem, nelements, pcount;
-
-      char extname[] = "Test_table";           /* extension name */
-
-      /* define the name, data type, and physical units for the 2 columns */
-      char *ttype[] = { "Col_1", "Col_2", "Col_3" };
-      char *tform[] = { "1U",      "1V",    "1S"};  /* special CFITSIO codes */
-      char *tunit[] = { " ",        " ",    " " };
-       ...
-
-           /* write the header keywords */
-      status  = 0;
-      nrows   = 1;
-      tfields = 3
-      pcount  = 0;
-      fits_create_tbl(fptr, BINARY_TBL, nrows, tfields, ttype, tform,
-                tunit, extname, &status);
-
-           /* write the unsigned shorts to the 1st column */
-      colnum    = 1;
-      firstrow  = 1;
-      firstelem = 1;
-      nelements = 100;
-      fits_write_col(fptr, TUSHORT, colnum, firstrow, firstelem,
-              nelements, uarray, &status);
-
-           /* now write the unsigned longs to the 2nd column */
-      colnum    = 2;
-      fits_write_col(fptr, TUINT, colnum, firstrow, firstelem,
-              nelements, varray, &status);
-       ...
-\end{verbatim}
-Note that the non-standard TFORM values for the 3 columns, `U' and `V',
-tell CFITSIO to write the keywords appropriate for unsigned 16-bit and
-unsigned 32-bit integers, respectively (i.e., TFORMn = '1I' and TZEROn
-= 32678 for unsigned 16-bit integers, and TFORMn = '1J' and TZEROn =
-2147483648 for unsigned 32-bit integers).  The 'S' TFORMn value tells
-CFITSIO to write the keywords appropriate for a signed 8-bit byte column
-with TFORMn = '1B' and TZEROn = -128.  The calls to fits\_write\_col
-then write the arrays of unsigned integer values to the columns.
-
-
-\section{Dealing with Character Strings}
-
-The character string values in a FITS header or in an ASCII column in a
-FITS table extension are generally padded out with non-significant
-space characters (ASCII 32) to fill up the header record or the column
-width.  When reading a FITS string value, the CFITSIO routines will
-strip off these non-significant trailing spaces and will return a
-null-terminated string value containing only the significant
-characters.  Leading spaces in a FITS string are considered
-significant.  If the string contains all blanks, then CFITSIO will
-return a single blank character, i.e, the first blank is considered to
-be significant, since it distinguishes the string from a null or
-undefined string, but the remaining trailing spaces are not
-significant.
-
-Similarly, when writing string values to a FITS file the
-CFITSIO routines expect to get a null-terminated string as input;
-CFITSIO will pad the string with blanks if necessary when writing it
-to the FITS file.
-
-When calling CFITSIO routines that return a character string it is
-vital that the size of the char array be large enough to hold the
-entire string of characters, otherwise CFITSIO will overwrite whatever
-memory locations follow the char array, possibly causing the program to
-execute incorrectly.  This type of error can be difficult to debug, so
-programmers should always ensure that the char arrays are allocated
-enough space to hold the longest possible string, {\bf including} the
-terminating NULL character.  The fitsio.h file contains the following
-defined constants which programmers are strongly encouraged to use
-whenever they are allocating space for char arrays:
-
-\begin{verbatim}
-#define FLEN_FILENAME 1025 /* max length of a filename */
-#define FLEN_KEYWORD   72  /* max length of a keyword  */
-#define FLEN_CARD      81  /* length of a FITS header card */
-#define FLEN_VALUE     71  /* max length of a keyword value string */
-#define FLEN_COMMENT   73  /* max length of a keyword comment string */
-#define FLEN_ERRMSG    81  /* max length of a CFITSIO error message */
-#define FLEN_STATUS    31  /* max length of a CFITSIO status text string */
-\end{verbatim}
-For example, when declaring a char array to hold the value string
-of FITS keyword, use the following statement:
-
-\begin{verbatim}
-    char value[FLEN_VALUE];
-\end{verbatim}
-Note that FLEN\_KEYWORD is longer than needed for the nominal 8-character
-keyword name because the HIERARCH convention supports longer keyword names.
-
-
-\section{Implicit Data Type Conversion}
-
-The CFITSIO routines that read and write numerical data can perform
-implicit data type conversion.  This means that the data type of the
-variable or array in the program does not need to be the same as the
-data type of the value in the FITS file.  Data type conversion is
-supported for numerical and string data types (if the string contains a
-valid number enclosed in quotes) when reading a FITS header keyword
-value and for numeric values when reading or writing values in the
-primary array or a table column.  CFITSIO returns status =
-NUM\_OVERFLOW  if the converted data value exceeds the range of the
-output data type.  Implicit data type conversion is not supported
-within binary tables for string, logical, complex, or double complex
-data types.
-
-In addition, any table column may be read as if it contained string values.
-In the case of numeric columns the returned string will be formatted
-using the TDISPn display format if it exists.
-
-
-\section{Data Scaling}
-
-When reading numerical data values in the primary array or a
-table column, the values will be scaled automatically by the BSCALE and
-BZERO (or TSCALn and TZEROn) header values if they are
-present in the header.  The scaled data that is returned to the reading
-program will have
-
-\begin{verbatim}
-        output value = (FITS value) * BSCALE + BZERO
-\end{verbatim}
-(a corresponding formula using TSCALn and TZEROn is used when reading
-from table columns).  In the case of integer output values the floating
-point scaled value is truncated to an integer (not rounded to the
-nearest integer).  The fits\_set\_bscale and fits\_set\_tscale routines
-(described in the `Advanced' chapter) may be used to override the
-scaling parameters defined in the header (e.g., to turn off the scaling
-so that the program can read the raw unscaled values from the FITS
-file).
-
-When writing numerical data to the primary array or to a table column
-the data values will generally be automatically inversely scaled by the
-value of the BSCALE and BZERO (or TSCALn and TZEROn) keyword values if
-they they exist in the header.  These keywords must have been written
-to the header before any data is written for them to have any immediate
-effect.  One may also use the fits\_set\_bscale and fits\_set\_tscale
-routines to define or override the scaling keywords in the header
-(e.g., to turn off the scaling so that the program can write the raw
-unscaled values into the FITS file). If scaling is performed, the
-inverse scaled output value that is written into the FITS file will
-have
-
-\begin{verbatim}
-         FITS value = ((input value) - BZERO) / BSCALE
-\end{verbatim}
-(a corresponding formula using TSCALn and TZEROn is used when
-writing to table columns).  Rounding to the nearest integer, rather
-than truncation, is performed when writing integer data types to the
-FITS file.
-
-
-\section{Support for IEEE Special Values}
-
-The ANSI/IEEE-754 floating-point number standard defines certain
-special values that are used to represent such quantities as
-Not-a-Number (NaN), denormalized, underflow, overflow, and infinity.
-(See the Appendix in the NOST FITS standard or the NOST FITS User's
-Guide for a list of these values).  The CFITSIO routines that read
-floating point data in FITS files recognize these IEEE special values
-and by default interpret the overflow and infinity values as being
-equivalent to a NaN, and convert the underflow and denormalized values
-into zeros.  In some cases programmers may want access to the raw IEEE
-values, without any modification by CFITSIO.  This can be done by
-calling the fits\_read\_img or fits\_read\_col routines while
-specifying 0.0 as the value of the NULLVAL parameter.  This will force
-CFITSIO to simply pass the IEEE values through to the application
-program without any modification.  This is not fully supported on
-VAX/VMS machines, however, where there is no easy way to bypass the
-default interpretation of the IEEE special values.  This is also not
-supported when reading floating-point images that have been compressed
-with the FITS tiled image compression convention that is discussed in
-section 5.6;  the pixels values in tile compressed images are
-represented by scaled integers, and a reserved integer value
-(not a NaN) is used to represent undefined pixels.
-
-
-\section{Error Status Values and the Error Message Stack}
-
-Nearly all the CFITSIO routines return an error status value
-in 2 ways: as the value of the last parameter in the function call,
-and as the returned value of the function itself.  This provides
-some flexibility in the way programmers can test if an error
-occurred, as illustrated in the following 2 code fragments:
-
-\begin{verbatim}
-    if ( fits_write_record(fptr, card, &status) )
-         printf(" Error occurred while writing keyword.");
-
-or,
-
-    fits_write_record(fptr, card, &status);
-    if ( status )
-         printf(" Error occurred while writing keyword.");
-\end{verbatim}
-A listing of all the CFITSIO status code values is given at the end of
-this document.  Programmers are encouraged to use the symbolic
-mnemonics (defined in fitsio.h) rather than the actual integer status
-values to improve the readability of their code.
-
-The CFITSIO library uses an `inherited status' convention for the
-status parameter which means that if a routine is called with a
-positive input value of the status parameter as input, then the routine
-will exit immediately without changing the value of the status
-parameter.  Thus, if one passes the status value returned from each
-CFITSIO routine as input to the next CFITSIO routine, then whenever an
-error is detected all further CFITSIO processing will cease.  This
-convention can simplify the error checking in application programs
-because it is not necessary to check the value of the status parameter
-after every single CFITSIO routine call.  If a program contains a
-sequence of several CFITSIO calls, one can just check the status value
-after the last call.  Since the returned status values are generally
-distinctive, it should be possible to determine which routine
-originally returned the error status.
-
-CFITSIO also maintains an internal stack of error messages
-(80-character maximum length)  which in many cases provide a more
-detailed explanation of the cause of the error than is provided by the
-error status number alone.  It is recommended that the error message
-stack be printed out whenever a program detects a CFITSIO error.  The
-function fits\_report\_error will print out the entire error message
-stack, or alternatively one may call fits\_read\_errmsg to get the
-error messages one at a time.
-
-
-\section{Variable-Length Arrays in Binary Tables}
-
-CFITSIO provides easy-to-use support for reading and writing data in
-variable length fields of a binary table. The variable length columns
-have TFORMn keyword values of the form `1Pt(len)' where `t' is the
-data type code (e.g., I, J, E, D, etc.) and `len' is an integer
-specifying the maximum length of the vector in the table.  (CFITSIO also
-supports the experimental 'Q' datatype, which is identical to the 'P' type
-except that is supports is a 64-bit address space and hence much larger
-data structures).  If the value
-of `len' is not specified when the table is created (e.g., if the TFORM
-keyword value is simply specified as '1PE' instead of '1PE(400) ), then
-CFITSIO will automatically scan the table when it is closed to
-determine the maximum length of the vector and will append this value
-to the TFORMn value.
-
-The same routines that read and write data in an ordinary fixed length
-binary table extension are also used for variable length fields,
-however, the routine parameters take on a slightly different
-interpretation as described below.
-
-All the data in a variable length field is written into an area called
-the `heap' which follows the main fixed-length FITS binary table. The
-size of the heap, in bytes, is specified by the PCOUNT keyword in the
-FITS header. When creating a new binary table, the initial value of
-PCOUNT should usually be set to zero. CFITSIO will recompute the size
-of the heap as the data is written and will automatically update the
-PCOUNT keyword value when the table is closed.  When writing variable
-length data to a table, CFITSIO will automatically extend the size
-of the heap area if necessary, so that any following HDUs do not
-get overwritten.
-
-By default the heap data area starts immediately after the last row of
-the fixed-length table.  This default starting location may be
-overridden by the THEAP keyword, but this is not recommended.
-If additional rows of data are added to the table, CFITSIO will
-automatically shift the the heap down to make room for the new
-rows, but it is obviously be more efficient to initially
-create the table with the necessary number of blank rows, so that
-the heap does not needed to be constantly moved.
-
-When writing row of data to a variable length field the entire array of values for
-a given row of the table must be written with a single call to
-fits\_write\_col.
-The total length of the array is given by nelements
-+ firstelem - 1.  Additional elements cannot be appended to an existing
-vector at a later time since any attempt to do so will simply overwrite
-all the previously written data and the new data will be
-written to a new area of the heap.  The fits\_compress\_heap routine
-is provided to compress the heap and recover any unused space.
-To avoid having to deal with this issue, it is recommended
-that rows in a variable length field should only be written once.
-An exception to
-this general rule occurs when setting elements of an array as
-undefined.  It is allowed to first write a dummy value into the array with
-fits\_write\_col, and then call fits\_write\_col\_nul to flag the
-desired elements as undefined. Note that the rows of a table,
-whether fixed or variable length, do not have to be written
-consecutively and may be written in any order.
-
-When writing to a variable length ASCII character field (e.g., TFORM =
-'1PA') only a single character string can be written.  The `firstelem'
-and `nelements' parameter values in the fits\_write\_col routine are
-ignored and the number of characters to write is simply determined by
-the length of the input null-terminated character string.
-
-The fits\_write\_descript routine is useful in situations where
-multiple rows of a variable length column have the identical array of
-values.  One can simply write the array once for the first row, and
-then use fits\_write\_descript to write the same descriptor values into
-the other rows;  all the rows will then point to the same storage
-location thus saving disk space.
-
-When reading from a variable length array field one can only read as
-many elements as actually exist in that row of the table; reading does
-not automatically continue with the next row of the table as occurs
-when reading an ordinary fixed length table field.  Attempts to read
-more than this will cause an error status to be returned.  One can
-determine the number of elements in each row of a variable column with
-the fits\_read\_descript routine.
-
-
-\section{Multiple Access to the Same FITS File}
-
-CFITSIO supports simultaneous read and write access to multiple HDUs in
-the same FITS file.  Thus, one can open the same FITS file twice within
-a single program and move to 2 different HDUs in the file, and then
-read and write data or keywords to the 2 extensions just as if one were
-accessing 2 completely separate FITS files.   Since in general it is
-not possible to physically open the same file twice and then expect to
-be able to simultaneously (or in alternating succession) write to 2
-different locations in the file, CFITSIO recognizes when the file to be
-opened (in the call to fits\_open\_file) has already been opened and
-instead of actually opening the file again, just logically links the
-new file to the old file.  (This of course does not prevent the same
-file from being simultaneously opened by more than one program).  Then
-before CFITSIO reads or writes to either (logical) file, it makes sure
-that any modifications made to the other file have been completely
-flushed from the internal buffers to the file.  Thus, in principle, one
-could open a file twice, in one case pointing to the first extension
-and in the other pointing to the 2nd extension and then write data to
-both extensions, in any order, without danger of corrupting the file.
-There may be some efficiency penalties in doing this however, since
-CFITSIO has to flush all the internal buffers related to one file
-before switching to the  other, so it would still be prudent to
-minimize the number of times one switches back and forth between doing
-I/O to different HDUs in the same file.
-
-Some restriction apply:  a FITS file cannot be opened the first time
-with READONLY access, and then opened a second time with READWRITE access,
-because this may be phyically impossible (e.g., if the file resides
-on read-only media such as a CDROM).  Also, in multi-threaded environoments,
-one should never open the same file with write access in different threads.
-
-
-\section{When the Final Size of the FITS HDU is Unknown}
-
-It is not required to know the total size of a FITS data array or table
-before beginning to write the data to the FITS file.  In the case of
-the primary array or an image extension, one should initially create
-the array with the size of the highest dimension (largest NAXISn
-keyword) set to a dummy value, such as 1.  Then after all the data have
-been written and the true dimensions are known, then the NAXISn value
-should be updated using the fits\_update\_key routine before moving to
-another extension or closing the FITS file.
-
-When writing to FITS tables, CFITSIO automatically keeps track of the
-highest row number that is written to, and will increase the size of
-the table if necessary.  CFITSIO will also automatically insert space
-in the FITS file if necessary, to ensure that the data 'heap', if it
-exists, and/or any additional HDUs that follow the table do not get
-overwritten as new rows are written to the table.
-
-As a general rule it is best to specify the initial number of rows = 0
-when the table is created, then let CFITSIO keep track of the number of
-rows that are actually written.  The application program should not
-manually update the number of rows in the table (as given by the NAXIS2
-keyword) since CFITSIO does this automatically.  If a table is
-initially created with more than zero rows, then this will usually be
-considered as the minimum size of the table, even if fewer rows are
-actually written to the table.  Thus, if a table is initially created
-with NAXIS2 = 20, and CFITSIO only writes 10 rows of data before
-closing the table, then NAXIS2 will remain equal to 20.  If however, 30
-rows of data are written to this table, then NAXIS2 will be increased
-from 20 to 30.  The one exception to this automatic updating of the
-NAXIS2 keyword is if the application program directly modifies the
-value of NAXIS2 (up or down) itself just before closing the table.  In this
-case, CFITSIO does not update NAXIS2 again, since it assumes that the
-application program must have had a good reason for changing the value
-directly.  This is not recommended, however, and is only provided for
-backward compatibility with software that initially creates a table
-with a large number of rows, than decreases the NAXIS2 value to the
-actual smaller value just before closing the table.
-
-
-\section{CFITSIO Size Limitations}
-
-CFITSIO places very few restrictions on the size of FITS files that it
-reads or writes.  There are a few limits, however, that may affect
-some extreme cases:
-
-1.  The maximum number of FITS files that may be simultaneously opened
-by CFITSIO is set by NMAXFILES as defined in fitsio2.h.  It is currently
-set = 300 by default.  CFITSIO will allocate about 80 * NMAXFILES bytes
-of memory for internal use.  Note that the underlying C compiler or
-operating system, may have a smaller limit on the number of opened files.
-The C symbolic constant FOPEN\_MAX is intended to define the maximum
-number of files that may open at once (including any other text or
-binary files that may be open, not just FITS files).  On some systems it
-has been found that gcc supports a maximum of 255 opened files.
-
-2.  It used to be common for computer systems to only support disk files up
-to 2**31 bytes = 2.1 GB in size, but most systems now support larger files.
-CFITSIO can optionally read and write these so-called 'large files' that
-are greater than 2.1 GB on
-platforms where they are supported, but this
-usually requires that special compiler option flags be specified to turn
-on this  option.  On linux and solaris systems the compiler flags are
-'-D\_LARGEFILE\_SOURCE' and  `-D\_FILE\_OFFSET\_BITS=64'. These flags
-may also work on other platforms but this has not been tested.  Starting
-with version 3.0 of CFITSIO, the default Makefile that is distributed
-with CFITSIO will include these 2 compiler flags when building on Solaris
-and Linux PC systems.   Users on other platforms will need to add these
-compiler flags manually if they want to support large files.  In most
-cases it appears that it is not necessary to include these compiler
-flags when compiling application code that call the CFITSIO library
-routines.
-
-When CFITSIO is built with large file support (e.g., on Solaris and
-Linux PC system by default) then it can read and write FITS data files
-on disk that have any of these conditions:
-
-\begin{itemize}
-\item
-FITS files larger than 2.1 GB in size
-\item
-FITS images containing greater than 2.1 G pixels
-\item
-FITS images that have one dimension with more than 2.1 G pixels
-(as given by one of the NAXISn keyword)
-\item
-FITS tables containing more than 2.1E09 rows (given by the NAXIS2 keyword),
-or with rows that are more than 2.1 GB wide (given by the NAXIS1 keyword)
-\item
-FITS binary tables with a variable-length array heap that is larger
-than 2.1 GB (given by the PCOUNT keyword)
-\end{itemize}
-
-The current maximum FITS file size supported by  CFITSIO
-is about 6 terabytes (containing
-2**31 FITS blocks, each 2880 bytes in size). Currently, support for large
-files in CFITSIO has been tested on the Linux, Solaris, and IBM AIX
-operating systems.
-
-Note that when writing application programs that are intended to support
-large files it is important to use 64-bit integer variables
-to store quantities such as the dimensions of images, or the number of
-rows in a table.  These programs must also call the special versions
-of some of the CFITSIO routines that have been adapted to
-support 64-bit integers.  The names of these routines end in
-'ll' ('el' 'el') to distinguish them from the 32-bit integer
-version (e.g.,  fits\_get\_num\_rowsll).

-\chapter{Basic CFITSIO Interface Routines }
-
-This chapter describes the basic routines in the CFITSIO user interface
-that provide all the functions normally needed to read and write most
-FITS files.  It is recommended that these routines be used for most
-applications and that the more advanced routines described in the
-next chapter only be used in special circumstances when necessary.
-
-The following conventions are used in this chapter in the description
-of each function:
-
-1. Most functions have 2 names: a long descriptive name and a short
-concise name.  Both names are listed on the first line of the following
-descriptions, separated by a slash (/) character.  Programmers may use
-either name in their programs but the long names are recommended to
-help document the code and make it easier to read.
-
-2. A right arrow symbol ($>$) is used in the function descriptions to
-separate the input parameters from the output parameters in the
-definition of each routine.  This symbol is not actually part of the C
-calling sequence.
-
-3. The function parameters are defined in more detail in the
-alphabetical listing in Appendix B.
-
-4.  The first argument in almost all the functions is a pointer to a
-structure of type `fitsfile'.  Memory for this structure is allocated
-by CFITSIO when the FITS file is first opened or created and is freed
-when the FITS file is closed.
-
-5.  The last argument in almost all the functions is the error status
-parameter.  It must be equal to 0 on input, otherwise the function will
-immediately exit without doing anything.  A non-zero output value
-indicates that an error occurred in the function.  In most cases the
-status value is also returned as the value of the function itself.
-
-
-\section{CFITSIO Error Status Routines}
-
-
-\begin{description}
-\item[1 ] Return a descriptive text string (30 char max.) corresponding to
-   a CFITSIO error status code.\label{ffgerr}
-\end{description}
-
-\begin{verbatim}
-  void fits_get_errstatus / ffgerr (int status, > char *err_text)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Return the top (oldest) 80-character error message from the
-    internal CFITSIO stack of error messages and shift any remaining
-    messages on the stack up one level.  Call this routine
-    repeatedly to get each message in sequence.  The function returns
-   a value = 0 and a null error message when the error stack is empty.
-\label{ffgmsg}
-\end{description}
-
-\begin{verbatim}
-  int fits_read_errmsg / ffgmsg (char *err_msg)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Print out the error message corresponding to the input status
-    value and all the error messages on the CFITSIO stack to the specified
-    file stream  (normally to stdout or stderr).  If the input
-    status value = 0 then this routine does nothing.
-\label{ffrprt}
-\end{description}
-
-\begin{verbatim}
-  void fits_report_error / ffrprt (FILE *stream, status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]The fits\_write\_errmark routine puts an invisible marker on the
-   CFITSIO error stack.  The fits\_clear\_errmark routine can then be
-   used to delete any more recent error messages on the stack, back to
-   the position of the marker.  This preserves any older error messages
-   on the stack.  The fits\_clear\_errmsg routine simply clears all the
-   messages (and marks) from the stack.  These routines are called
-   without any arguments.
-\label{ffpmrk}  \label{ffcmsg}
-\end{description}
-
-\begin{verbatim}
-  void fits_write_errmark / ffpmrk (void)
-  void fits_clear_errmark / ffcmrk (void)
-  void fits_clear_errmsg / ffcmsg (void)
-\end{verbatim}
-
-
-\section{FITS File Access Routines}
-
-
-\begin{description}
-\item[1 ] Open an existing data file. \label{ffopen}
-
-
-\begin{verbatim}
-int fits_open_file / ffopen
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_diskfile / ffdkopen
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_data / ffdopn
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_table / fftopn
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-
-int fits_open_image / ffiopn
-    (fitsfile **fptr, char *filename, int iomode, > int *status)
-\end{verbatim}
-
-The iomode parameter determines the read/write access allowed in the
-file and can have values of READONLY (0) or READWRITE (1). The filename
-parameter gives the name of the file to be opened, followed by an
-optional argument giving the name or index number of the extension
-within the FITS file that should be moved to and opened (e.g.,
-\verb-myfile.fits+3- or \verb-myfile.fits[3]- moves to the 3rd extension within
-the file, and \verb-myfile.fits[events]- moves to the extension with the
-keyword EXTNAME = 'EVENTS').
-
-The fits\_open\_diskfile routine is similar to the fits\_open\_file routine
-except that it does not support the extended filename syntax in the input
-file name.  This routine simply tries to open the specified input file
-on magnetic disk.  This routine is mainly for use in cases where the
-filename (or directory path) contains square or curly bracket characters
-that would confuse the extended filename parser.
-
-The fits\_open\_data routine is similar to the fits\_open\_file routine
-except that it will move to the first HDU containing significant data,
-if a HDU name or number to open was not explicitly specified as
-part of the filename.  In this case, it will look for the first
-IMAGE HDU with NAXIS greater than 0, or the first table that does not contain the
-strings `GTI' (Good Time Interval extension) or `OBSTABLE' in the
-EXTNAME keyword value.
-
-The fits\_open\_table and fits\_open\_image routines are similar to
-fits\_open\_data except they will move to the first significant table
-HDU or image HDU in the file, respectively, if a HDU name or
-number is not specified as part of the filename.
-
-IRAF images (.imh format files) and raw binary data arrays may also be
-opened with READONLY access.  CFITSIO will automatically test if the
-input file is an IRAF image, and if, so will convert it on the fly into
-a virtual FITS image before it is opened by the application program.
-If the input file is a raw binary data array of numbers, then the data type
-and dimensions of the array must be specified in square brackets
-following the name of the file (e.g.  'rawfile.dat[i512,512]' opens a
-512 x 512 short integer image).  See the `Extended File Name Syntax'
-chapter for more details on how to specify the raw file name.  The raw
-file is converted on the fly into a virtual FITS image in memory that
-is then opened by the application program with READONLY access.
-
-Programs can read the input file from the 'stdin' file stream if a dash
-character ('-') is given as the filename. Files can also be opened over
-the network using FTP or HTTP protocols by supplying the appropriate URL
-as the filename.
-
-The input file can be modified in various ways to create a virtual file
-(usually stored in memory) that is then opened by the application
-program by supplying a filtering or binning specifier in square brackets
-following the filename. Some of the more common filtering methods are
-illustrated in the following paragraphs, but users should refer to the
-'Extended File Name Syntax' chapter for a complete description of
-the full file filtering syntax.
-
-When opening an image, a rectangular subset of the physical image may be
-opened by listing the first and last pixel in each dimension (and
-optional pixel skipping factor):
-
-\begin{verbatim}
-myimage.fits[101:200,301:400]
-\end{verbatim}
-will create and open a 100x100 pixel virtual image of that section of
-the physical image, and \verb+myimage.fits[*,-*]+ opens a virtual image
-that is the same size as the physical image but has been flipped in
-the vertical direction.
-
-When opening a table, the filtering syntax can be used to add or delete
-columns or keywords in the virtual table:
-\verb-myfile.fits[events][col !time; PI = PHA*1.2]- opens a virtual table in which the TIME column
-has been deleted and a new PI column has been added with a value 1.2
-times that of the PHA column. Similarly, one can filter a table to keep
-only those rows that satisfy a selection criterion:
-\verb-myfile.fits[events][pha > 50]- creates and opens a virtual table
-containing only those rows with a PHA value greater than 50. A large
-number of boolean and mathematical operators can be used in the
-selection expression. One can also filter table rows using 'Good Time
-Interval' extensions, and spatial region filters as in
-\verb-myfile.fits[events][gtifilter()]- and
-\verb-myfile.fits[events][regfilter( "stars.rng")]-.
-
-Finally, table columns may be binned or histogrammed to generate a
-virtual image. For example, \verb-myfile.fits[events][bin (X,Y)=4]- will
-result in a 2-dimensional image calculated by binning the X and Y
-columns in the event table with a bin size of 4 in each dimension. The
-TLMINn and TLMAXn keywords will be used by default to determine the
-range of the image.
-
-A single program can open the same FITS file more than once and then
-treat the resulting fitsfile pointers as though they were completely
-independent FITS files. Using this facility, a program can open a FITS
-file twice, move to 2 different extensions within the file, and then
- read and write data in those extensions in any order.
-\end{description}
-
-
-\begin{description}
-\item[2 ]  Create and open a new empty output FITS file. \label{ffinit}
-
-
-\begin{verbatim}
-int fits_create_file / ffinit
-    (fitsfile **fptr, char *filename, > int *status)
-
-int fits_create_diskfile / ffdkinit
-    (fitsfile **fptr, char *filename, > int *status)
-\end{verbatim}
-
-An error will be returned if the specified file already exists, unless
-the filename is prefixed with an exclamation point (!). In that case
-CFITSIO will overwrite (delete) any existing file with the same name.
-Note that the exclamation point is a special UNIX character so if
-it is used on the command line it must be preceded by a backslash to
-force the UNIX shell to accept the character as part of the filename.
-
-The output file will be written to the 'stdout' file stream if a dash
-character ('-') or the string 'stdout' is given as the filename. Similarly,
-'-.gz' or 'stdout.gz' will cause the file to be gzip compressed before
-it is written out to the stdout stream.
-
-Optionally, the name of a template file that is used to define the
-structure of the new file may be specified in parentheses following the
-output file name. The template file may be another FITS file, in which
-case the new file, at the time it is opened, will be an exact copy of
-the template file except that the data structures (images and tables)
-will be filled with zeros. Alternatively, the template file may be an
-ASCII format text file containing directives that define the keywords to be
-created in each HDU of the file. See the 'Extended File Name Syntax'
- section for a complete description of the template file syntax.
-
-The fits\_create\_diskfile routine is similar to the fits\_create\_file routine
-except that it does not support the extended filename syntax in the input
-file name.  This routine simply tries to create the specified file
-on magnetic disk.  This routine is mainly for use in cases where the
-filename (or directory path) contains square or curly bracket characters
- that would confuse the extended filename parser.
-\end{description}
-
-
-
-\begin{description}
-\item[3 ] Close a previously opened FITS file.  The first routine simply
-closes the file, whereas the second one also DELETES THE FILE, which
-can be useful in cases where a FITS file has been partially created,
-but then an error occurs which prevents it from being completed.
- \label{ffclos} \label{ffdelt}
-\end{description}
-
-\begin{verbatim}
-  int fits_close_file / ffclos (fitsfile *fptr, > int *status)
-
-  int fits_delete_file / ffdelt (fitsfile *fptr, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]Return the name, I/O mode (READONLY or READWRITE), and/or the file
-type (e.g. 'file://', 'ftp://') of the opened FITS file. \label{ffflnm}
- \label{ffflmd} \label{ffurlt}
-\end{description}
-
-\begin{verbatim}
-  int fits_file_name / ffflnm (fitsfile *fptr, > char *filename, int *status)
-
-  int fits_file_mode / ffflmd (fitsfile *fptr, > int *iomode, int *status)
-
-  int fits_url_type / ffurlt (fitsfile *fptr, > char *urltype, int *status)
-\end{verbatim}
-
-\section{HDU Access Routines}
-
-The following functions perform operations on Header-Data Units (HDUs)
-as a whole.
-
-
-\begin{description}
-\item[1 ] Move to a different HDU in the file.  The first routine moves to a
-    specified absolute HDU number (starting with 1 for the primary
-    array) in the FITS file, and the second routine moves a relative
-    number HDUs forward or backward from the current HDU.  A null
-    pointer may be given for the hdutype parameter if it's value is not
-    needed.  The third routine moves to the (first) HDU which has the
-    specified extension type and EXTNAME and EXTVER keyword values (or
-    HDUNAME and HDUVER keywords).  The hdutype parameter may have a
-    value of IMAGE\_HDU, ASCII\_TBL, BINARY\_TBL, or ANY\_HDU where
-    ANY\_HDU means that only the extname and extver values will be used
-    to locate the correct extension.  If the input value of extver is 0
-    then the EXTVER keyword is ignored and the first HDU with a
-    matching EXTNAME (or HDUNAME) keyword will be found.  If no
-    matching HDU is found in the file then the current HDU will remain
-    unchanged and a status = BAD\_HDU\_NUM will be returned.
-  \label{ffmahd} \label{ffmrhd} \label{ffmnhd}
-\end{description}
-
-\begin{verbatim}
-  int fits_movabs_hdu / ffmahd
-      (fitsfile *fptr, int hdunum, > int *hdutype, int *status)
-
-  int fits_movrel_hdu / ffmrhd
-      (fitsfile *fptr, int nmove, > int *hdutype, int *status)
-
-  int fits_movnam_hdu / ffmnhd
-      (fitsfile *fptr, int hdutype, char *extname, int extver, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Return the total number of HDUs in the FITS file.  This returns the
-number of completely defined HDUs in the file.  If a new HDU has just been added to
-the FITS file, then that last HDU will only be counted if it has been closed,
-or if data has been written to the HDU.
-   The current HDU remains unchanged by this routine. \label{ffthdu}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_num_hdus / ffthdu
-      (fitsfile *fptr, > int *hdunum, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Return the number of the current HDU (CHDU) in the FITS file (where
-    the primary array = 1).  This function returns the HDU number
-   rather than a status value.  \label{ffghdn}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_hdu_num / ffghdn
-      (fitsfile *fptr, > int *hdunum)
-\end{verbatim}
-
-\begin{description}
-\item[4 ] Return the type of the current HDU in the FITS file.  The possible
-   values for hdutype are: IMAGE\_HDU, ASCII\_TBL, or BINARY\_TBL.  \label{ffghdt}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_hdu_type / ffghdt
-      (fitsfile *fptr, > int *hdutype, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[5 ] Copy all or part of the HDUs in the FITS file associated with infptr
-    and append them to the end of the FITS file associated with
-    outfptr.  If 'previous' is true (not 0), then any HDUs preceding
-    the current HDU in the input file will be copied to the output
-    file.  Similarly, 'current' and 'following' determine whether the
-    current HDU, and/or any following HDUs in the input file will be
-    copied to the output file. Thus, if all 3 parameters are true, then the
-    entire input file will be copied.  On exit, the current HDU in
-    the input file will be unchanged, and the last HDU in the output
-   file will be the current HDU.  \label{ffcpfl}
-\end{description}
-
-\begin{verbatim}
-  int fits_copy_file / ffcpfl
-      (fitsfile *infptr, fitsfile *outfptr, int previous, int current,
-          int following, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Copy the current HDU from the FITS file associated with infptr and append it
-    to the end of the FITS file associated with outfptr.  Space may be
-   reserved for MOREKEYS additional keywords in the output header. \label{ffcopy}
-\end{description}
-
-\begin{verbatim}
-  int fits_copy_hdu / ffcopy
-      (fitsfile *infptr, fitsfile *outfptr, int morekeys, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[7 ] Write the current HDU in the input FITS file to the
-   output FILE stream (e.g., to stdout). \label{ffwrhdu}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_hdu / ffwrhdu
-      (fitsfile *infptr, FILE *stream, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[8 ]  Copy the header (and not the data) from the CHDU associated with infptr
-    to the CHDU associated with outfptr.  If the current output HDU
-    is not completely empty, then the CHDU will be closed and a new
-    HDU will be appended to the output file.   An empty output data unit
-   will be created with all values initially = 0). \label{ffcphd}
-\end{description}
-
-\begin{verbatim}
-  int fits_copy_header / ffcphd
-      (fitsfile *infptr, fitsfile *outfptr, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[9 ]  Delete the CHDU in the FITS file.  Any following HDUs will be shifted
-    forward in the file, to fill in the gap created by the deleted
-    HDU.  In the case of deleting the primary array (the first HDU in
-    the file) then the current primary array will be replace by a null
-    primary array containing the minimum set of required keywords and
-    no data.  If there are more extensions in the file following the
-    one that is deleted, then the the CHDU will be redefined to point
-    to the following extension.  If there are no following extensions
-    then the CHDU will be redefined to point to the previous HDU.  The
-    output hdutype parameter returns the type of the new CHDU.  A null
-    pointer may be given for
-   hdutype if the returned value is not needed. \label{ffdhdu}
-\end{description}
-
-\begin{verbatim}
-  int fits_delete_hdu / ffdhdu
-      (fitsfile *fptr, > int *hdutype, int *status)
-\end{verbatim}
-
-\section{Header Keyword Read/Write Routines}
-
-These routines read or write keywords in the Current Header Unit
-(CHU).  Wild card characters (*, ?, or \#) may be used when specifying
-the name of the keyword to be read: a '?' will match any single
-character at that position in the keyword name and a '*' will match any
-length (including zero) string of characters.  The '\#' character will
-match any consecutive string of decimal digits (0 - 9).  When a wild
-card is used the routine will only search for a match from the current
-header position to the end of the header and will not resume the search
-from the top of the header back to the original header position as is
-done when no wildcards are included in the keyword name.  The
-fits\_read\_record routine may be used to set the starting position
-when doing wild card searches.  A status value of KEY\_NO\_EXIST is
-returned if the specified keyword to be read is not found in the
-header.

-\subsection{Keyword Reading Routines}
-
-
-\begin{description}
-\item[1 ] Return the number of existing keywords (not counting the
-    END keyword) and the amount of space currently available for more
-    keywords.  It returns morekeys = -1 if the header has not yet been
-    closed.  Note that CFITSIO will dynamically add space if required
-    when writing new keywords to a header so in practice there is no
-    limit to the number of keywords that can be added to a header.  A
-    null pointer may be entered for the morekeys parameter if it's
-   value is not needed. \label{ffghsp}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_hdrspace / ffghsp
-      (fitsfile *fptr, > int *keysexist, int *morekeys, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Return the specified keyword.  In the first routine,
-    the datatype parameter specifies the desired returned data type of the
-    keyword value and can have one of the following symbolic constant
-    values:  TSTRING, TLOGICAL (== int), TBYTE, TSHORT, TUSHORT, TINT,
-    TUINT, TLONG, TULONG, TLONGLONG, TFLOAT, TDOUBLE, TCOMPLEX, and TDBLCOMPLEX.
-    Within the context of this routine, TSTRING corresponds to a
-    'char*' data type, i.e., a pointer to a character array.  Data type
-    conversion will be performed for numeric values if the keyword
-    value does not have the same data type.  If the value of the keyword
-    is undefined (i.e., the value field is blank) then an error status
-    = VALUE\_UNDEFINED will be returned.
-
-    The second routine returns the keyword value as a character string
-    (a literal copy of what is in the value field) regardless of the
-    intrinsic data type of the keyword.  The third routine returns
-    the entire 80-character header record of the keyword, with any
-    trailing blank characters stripped off. The fourth routine returns
-    the (next) header record that contains the literal string of characters
-    specified by the 'string' argument.
-
-    If a NULL comment pointer is supplied then the comment string
-   will not be returned. \label{ffgky} \label{ffgkey} \label{ffgcrd}
-\end{description}

-  int fits_read_str / ffgstr
-      (fitsfile *fptr, char *string, > char *card, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Return the nth header record in the CHU.  The first keyword
-   in the header is at keynum = 1;  if keynum = 0 then these routines
-   simply reset the internal CFITSIO pointer to the beginning of the header
-   so that subsequent keyword operations will start at the top of the
-   header (e.g., prior to searching for keywords using wild cards in
-   the keyword name).   The first routine returns the entire
-   80-character header record (with trailing blanks truncated),
-   while the second routine parses the record and returns the name,
-   value, and comment fields as separate (blank truncated)
-   character strings.  If a NULL comment pointer is given on input,
-   then the comment string will not be
-  returned. \label{ffgrec} \label{ffgkyn}
-\end{description}

-       char *comment, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ] Return the next keyword whose name matches one of the strings in
-    'inclist' but does not match any of the strings in 'exclist'.
-    The strings in inclist and exclist may contain wild card characters
-    (*, ?, and \#) as described at the beginning of this section.
-    This routine searches from the current header position to the
-    end of the header, only, and does not continue the search from
-    the top of the header back to the original position.  The current
-    header position may be reset with the ffgrec routine.  Note
-    that nexc may be set = 0 if there are no keywords to be excluded.
-    This routine returns status = KEY\_NO\_EXIST if a matching
-   keyword is not found. \label{ffgnxk}
-\end{description}

-       int nexc, > char *card, int  *status)
-\end{verbatim}
-
-\begin{description}
-\item[5 ] Return the physical units string from an existing keyword.  This
-    routine uses a local convention, shown in the following example,
-    in which the keyword units are enclosed in square brackets in the
-    beginning of the keyword comment field.  A null string is returned
-   if no units are defined for the keyword.  \label{ffgunt}
-\end{description}
-
-\begin{verbatim}

-      (fitsfile *fptr, char *keyname, > char *unit, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Concatenate the header keywords in the CHDU into a single long
-    string of characters.  This provides a convenient way of passing
-    all or part of the header information in a FITS HDU to other subroutines.
-    Each 80-character fixed-length keyword record is appended to the
-    output character string, in order, with no intervening separator or
-    terminating characters. The last header record is terminated with
-    a NULL character.  These routine allocates memory for the returned
-    character array, so the calling program must free the memory when
-    finished.  The cleanest way to do this is to
-    call the fits\_free\_memory routine.
-
-    There are 2 related routines: fits\_hdr2str simply concatenates all
-    the existing keywords in the header; fits\_convert\_hdr2str is similar,
-    except that if the CHDU is a tile compressed image (stored in a binary
-    table) then it will first convert that header back to that of the corresponding
-    normal FITS image before concatenating the keywords.
-
-    Selected keywords may be excluded from the returned character string.
-    If the second parameter (nocomments) is TRUE (nonzero) then any
-    COMMENT, HISTORY, or blank keywords in the header will not be copied
-    to the output string.
-
-    The 'exclist' parameter may be used to supply a list of keywords
-    that are to be excluded from the output character string. Wild card
-    characters (*, ?, and \#) may be used in the excluded keyword names.
-    If no additional keywords are to be excluded, then set nexc = 0 and
-   specify NULL for the the **exclist  parameter.  \label{ffhdr2str}
-\end{description}

-\subsection{Keyword Writing Routines}
-
-
-\begin{description}
-\item[1 ] Write a keyword of the appropriate data type into the
-    CHU.  The first routine simply appends a new keyword whereas the
-    second routine will update the value and comment fields of the
-    keyword if it already exists, otherwise it appends a new
-    keyword.  Note that the address to the value, and not the value
-    itself, must be entered.    The datatype parameter specifies the
-    data type of the keyword value with one of the following values:
-    TSTRING, TLOGICAL (== int), TBYTE, TSHORT, TUSHORT, TINT, TUINT,
-    TLONG, TLONGLONG, TULONG, TFLOAT, TDOUBLE.  Within the context of this
-    routine, TSTRING corresponds to a 'char*' data type, i.e., a pointer
-    to a character array.  A null pointer may be entered for the
-    comment parameter in which case the  keyword comment
-   field will be unmodified or left blank.  \label{ffpky} \label{ffuky}

-\end{verbatim}
-
-\begin{description}
-\item[2 ] Write a keyword with a null or undefined value (i.e., the
-    value field in the keyword is left blank).  The first routine
-    simply appends a new keyword whereas the second routine will update
-    the value and comment fields of the keyword if it already exists,
-    otherwise it appends a new keyword.  A null pointer may be
-    entered for the comment parameter in which case the  keyword
-    comment

-\end{verbatim}
-
-\begin{description}
-\item[4 ] Write the DATE keyword to the CHU. The keyword value will contain
-    the current system date as a character string in 'yyyy-mm-ddThh:mm:ss'
-    format. If a DATE keyword already exists in the header, then this
-    routine will simply update the keyword value with the current date.

-\section{Primary Array or IMAGE Extension I/O Routines}
-
-These routines read or write data values in the primary data array (i.e.,
-the first HDU in a FITS file) or an IMAGE extension.   There are also
-routines to get information about the data type and size of the image.
-Users should also read the following chapter on the CFITSIO iterator
-function which provides a more `object oriented' method of reading and
-writing images.  The iterator function is a little more complicated to
-use, but the advantages are that it usually takes less code to perform
-the same operation, and the resulting program often runs faster because
-the FITS files are read and written using the most efficient block size.
-
-C programmers should note that the ordering of arrays in FITS files, and
-hence in all the CFITSIO calls, is more similar to the dimensionality
-of arrays in Fortran rather than C.  For instance if a FITS image has
-NAXIS1 = 100 and NAXIS2 = 50, then a 2-D array just large enough to hold
-the image should be declared as array[50][100] and not as array[100][50].
-
-The `datatype'  parameter specifies the data type of the `nulval'  and
-`array' pointers and can have one of the following  values:  TBYTE,
-TSBYTE, TSHORT, TUSHORT, TINT, TUINT, TLONG, TLONGLONG, TULONG, TFLOAT,
-TDOUBLE.  Automatic data type conversion is performed if the data type
-of the FITS array (as defined by the BITPIX keyword) differs from that
-specified by 'datatype'.  The data values are also automatically scaled
-by the BSCALE and BZERO keyword values as they are being read or written
-in the FITS array.
-
-
-\begin{description}
-\item[1 ] Get the data type or equivalent data type of the image.  The
-    first routine returns the physical data type of the FITS image, as
-    given by the BITPIX keyword, with allowed values of BYTE\_IMG (8),
-    SHORT\_IMG (16), LONG\_IMG (32), LONGLONG\_IMG (64),
-    FLOAT\_IMG (-32), and DOUBLE\_IMG
-    (-64).
-    The second routine is similar, except that if the image pixel
-    values are scaled, with non-default values for the BZERO and BSCALE
-    keywords, then the routine will return the 'equivalent' data type
-    that is needed to store the scaled values.  For example, if BITPIX
-    = 16 and BSCALE = 0.1 then the equivalent data type is FLOAT\_IMG.
-    Similarly if BITPIX = 16, BSCALE = 1, and BZERO = 32768, then the
-    the pixel values span the range of an unsigned short integer and
-   the returned data type will be USHORT\_IMG. \label{ffgidt}

-\end{verbatim}
-
-\begin{description}
-\item[2 ] Get the number of dimensions, and/or the size of
-    each dimension in the image .  The number of axes in the image is
-    given by naxis, and the size of each dimension is given by the
-    naxes array (a maximum of maxdim dimensions will be returned).

-\end{verbatim}
-
-\begin{description}
-\item[3 ]Create a new primary array or IMAGE extension with a specified
-   data type and size.  If the FITS file is currently empty then a
-   primary array is created, otherwise a new IMAGE extension is
-  appended to the file. \label{ffcrim}

-
-\begin{description}
-\item[4 ] Copy an n-dimensional image in a particular row and column of a
-    binary table (in a vector column)
-    to or from a primary array or image extension.
-
-    The 'cell2image' routine
-    will append a new image extension (or primary array) to the output file.
-    Any WCS keywords associated with the input column image will be translated
-    into the appropriate form for an image extension.  Any other keywords
-    in the table header that are not specifically related to defining the
-    binary table structure or to other columns in the table
-    will also be copied to the header of the output image.
-
-    The 'image2cell' routine will copy the input image into the specified row
-    and column of the current binary table in the output file.  The binary table
-    HDU must exist before calling this routine, but it
-    may be empty, with no rows or columns of data.  The specified column
-    (and row) will be created if it does not already exist.  The 'copykeyflag'
-    parameter controls which keywords are copied from the input
-    image to the header of the output table: 0 = no keywords will be copied,
-    1 = all keywords will be copied (except those keywords that would be invalid in
-   the table header), and 2 = copy only the WCS keywords. \label{copycell}

-\item[5 ] Write a rectangular subimage (or the whole image) to the FITS data

-\begin{description}
-\item[6 ] Write pixels into the FITS data array.  'fpixel' is an array of
-   length NAXIS which gives the coordinate of the starting pixel to be
-   written to, such that fpixel[0] is in the range 1 to NAXIS1,
-   fpixel[1] is in the range 1 to NAXIS2, etc.  The first pair of routines
-   simply writes the array of pixels to the FITS file (doing data type
-   conversion if necessary) whereas the second routines will substitute
-   the  appropriate FITS null value for any elements which are equal to
-   the input value of nulval (note that this parameter gives the
-   address of the null value, not the null value itself).  For integer
-   FITS arrays, the FITS null value is defined by the BLANK keyword (an
-   error is returned if the BLANK keyword doesn't exist).  For floating
-   point FITS arrays  the special IEEE NaN (Not-a-Number) value will be
-   written into the FITS file.  If a null pointer is entered for
-   nulval, then the null value is ignored and this routine behaves

-\item[7 ] Set FITS data array elements equal to the appropriate null pixel
-    value. For integer FITS arrays, the FITS null value is defined by
-    the BLANK keyword  (an error is returned if the BLANK keyword
-    doesn't exist). For floating point FITS arrays the special IEEE NaN
-    (Not-a-Number) value will be written into the FITS file.  Note that

-    etc. The nelements parameter specifies the number of pixels to
-    read.  If fpixel is set to the first pixel, and nelements is set
-    equal to the NAXIS1 value, then this routine would read the first
-    row of the image.  Alternatively, if nelements is set equal to
-    NAXIS1 * NAXIS2 then it would read an entire 2D image, or the first
-    plane of a 3-D datacube.
-
-    The first 2 routines will return any undefined pixels in the FITS array
-    equal to the value of *nullval (note that this parameter gives the
-    address of the null value, not the null value itself) unless nulval
-    = 0 or *nulval = 0, in which case no checks for undefined pixels
-    will be performed.  The second 2 routines are similar except that any
-    undefined pixels will have the corresponding nullarray element set
-   equal to TRUE (= 1).  \label{ffgpxv}  \label{ffgpxf}

-\section{Image Compression}
-
-CFITSIO transparently supports the 2 methods of image compression described
-below.
-
-1)  The entire FITS file may be externally compressed with the gzip or Unix
-compress utility programs, producing a *.gz or *.Z file, respectively. When reading
-compressed files of this type, CFITSIO first uncompresses the entire file
-into memory before performing the requested read operations.  Output files
-can be directly written in the gzip compressed format if the user-specified
-filename ends with `.gz'.  In this case, CFITSIO initially writes the
-uncompressed file in memory and then compresses it and writes it to disk
-when the FITS file is closed, thus saving user disk space. Read and write
-access to these compressed FITS files is generally quite fast since all the
-I/O is performed in memory; the main limitation with this technique is that
-there must be enough available memory (or swap space) to hold the entire
-uncompressed FITS file.
-
-2) CFITSIO also supports the FITS tiled image compression convention in
-which the image is subdivided into a grid of rectangular tiles, and each
-tile of pixels is individually compressed.   The details of this FITS
-compression  convention are described at the FITS Support Office web site at
-http://fits.gsfc.nasa.gov/fits\_registry.html  Basically, the compressed
-image tiles are stored in rows of a variable length array column in a FITS
-binary table, however CFITSIO recognizes that this binary table extension
-contains an image and treats it as if it were an IMAGE extension.  This
-tile-compressed format is especially well suited for compressing very large
-images because a) the FITS header keywords remain uncompressed for rapid
-read access, and because b) it is possible to extract and uncompress
-sections of the image without having to uncompress the entire image. This
-format is also much more effective in compressing floating point images
-than simply compressing the image using gzip or compress because it
-approximates the floating point values with scaled integers which can then
-be compressed more efficiently.
-
-Currently CFITSIO supports 3 general purpose compression algorithms  plus
-one other special-purpose compression technique that is designed for data
-masks with positive integer pixel values. The 3 general purpose algorithms
-are GZIP, Rice, and HCOMPRESS, and the special purpose  algorithm is the
-IRAF pixel list compression technique (PLIO). In principle, any number of
-other compression algorithms could also be supported  by the FITS tiled
-image compression convention.
-
-The FITS image can be subdivided into any desired rectangular grid of
-compression tiles.  With the GZIP, Rice,  and PLIO algorithms, the default
-is to take each row of the image as a tile.  The HCOMPRESS algorithm is
-inherently 2-dimensional in nature, so the default in this case is to take
-16 rows of the image per tile. In most cases it makes little difference what
-tiling pattern is used, so the default tiles are usually adequate.  In the
-case of very small images, it could be more efficient to compress the whole
-image as a single tile. Note that the image dimensions are not required to
-be an integer multiple of the tile dimensions; if not, then the tiles at the
-edges of the image will be smaller than the other tiles.
-
-The 4 supported image compression algorithms are all 'loss-less' when
-applied to integer FITS images;  the pixel values are preserved exactly with
-no loss of information during the compression and uncompression process.  In
-addition, the HCOMPRESS algorithm supports a 'lossy' compression mode that
-will produce
-larger amount of image compression.  This is achieved by specifying a non-zero
-value for the HCOMPRESS ``scale''
-parameter.  Since the amount of compression that is achieved depends directly
-on the RMS noise in the image, it is usually more convention
-to specify the HCOMPRESS scale factor relative to the RMS noise.
-Setting s = 2.5 means use a scale factor that is 2.5 times the calculated RMS noise
-in the image tile.   In some cases
-it may be desirable to specify the exact scaling to be used,
-instead of specifying it relative to the calculated noise value.  This may
-be done by specifying the negative of desired scale value (typically
-in the range -2 to -100).
-
-Very high compression factors (of 100 or more) can be
-achieved by using large HCOMPRESS scale values, however, this can produce undesirable
-``blocky'' artifacts in the compressed image.  A variation of the HCOMPRESS
-algorithm (called HSCOMPRESS) can be used in this case to apply a small
-amount of smoothing of the image when it is uncompressed to help cover up
-these artifacts.  This smoothing is purely cosmetic and does not cause any
-significant change to the image pixel values.
-
-Floating point FITS images (which have BITPIX = -32 or -64) usually contain
-too much ``noise'' in the least significant bits of the mantissa of the
-pixel values  to be effectively compressed with any lossless algorithm.
-Consequently, floating point images are first quantized into scaled integer
-pixel values (and thus throwing away much of the noise) before being
-compressed with the specified algorithm (either GZIP, Rice, or HCOMPRESS).
-This technique produces much higher compression factors than
-simply using the GZIP utility to externally compress the whole FITS file,  but it also
-means that the original floating value pixel values are not exactly
-preserved. When done properly, this  integer scaling technique will only
-discard the insignificant noise while still preserving all the real
-information in the image.  The amount of precision that is retained in the
-pixel values is controlled by the "quantization level" parameter, q.  Larger
-values of q will result in compressed images whose pixels more closely match
-the floating point pixel values, but at the same time the amount of
-compression that is achieved will be reduced.  Users should experiment with
-different values for  this parameter to determine the optimal value that
-preserves all the useful information in the image, without needlessly
-preserving all the ``noise'' which will hurt the compression efficiency.
-
-The default value for the quantization scale factor is 16., which means that
-scaled integer pixel values will be quantized such that the difference
-between adjacent integer values will be 1/16th of the noise level in the
-image background. CFITSIO uses an optimized algorithm to accurately estimate
-the noise in the image.  As an example, if the RMS noise in the background
-pixels of an  image = 32.0,  then the spacing between adjacent scaled
-integer pixel values  will equal 2.0 by default.  Note that the RMS noise is
-independently calculated for each tile of the image, so the resulting
-integer scaling factor may fluctuate slightly for each tile.   In some cases
-it may be desirable to specify the exact quantization level to be used,
-instead of specifying it relative to the calculated noise value.  This may
-be done by specifying the negative of desired quantization level for the
-value of q.  In the previous example, one could specify q = -2.0 so that the
-quantized integer levels differ by 2.0.  Larger negative values for q means
-that the levels are more coarsely spaced, and will produce higher
-compression factors.
-
-There are 2 methods for specifying all the parameters needed to write a FITS
-image in the tile compressed format.  The parameters may either be specified
-at run time as part of the file name of the output compressed FITS file, or
-the writing program may call a set of helper CFITSIO subroutines that are provided
-for specifying the parameter values, as described below:
-
-1)  At run time, when specifying the name of the output FITS file to be
-created, the user can indicate that images should be
-written in tile-compressed format by enclosing the compression
-parameters in square brackets following the root disk file name
-in the following format:
-
-\begin{verbatim}
-    [compress NAME T1,T2; q QLEVEL, s HSCALE]
-\end{verbatim}
-where
-
-\begin{verbatim}
-    NAME   = algorithm name:  GZIP, Rice, HCOMPRESS, HSCOMPRSS or PLIO
-             may be abbreviated to the first letter (or HS for HSCOMPRESS)
-    T1,T2  = tile dimension (e.g. 100,100 for square tiles 100 pixels wide)
-    QLEVEL = quantization level for floating point FITS images
-    HSCALE = HCOMPRESS scale factor; default = 0 which is lossless.
-\end{verbatim}
-
-Here are a few examples of this extended syntax:
-
-
-\begin{verbatim}
-    myfile.fit[compress]    - use the default compression algorithm (Rice)
-                              and the default tile size (row by row)
-
-    myfile.fit[compress GZIP] - use the specified compression algorithm;
-    myfile.fit[compress Rice]     only the first letter of the algorithm
-    myfile.fit[compress PLIO]     name is required.
-    myfile.fit[compress HCOMP]
-
-    myfile.fit[compress R 100,100]   - use Rice and 100 x 100 pixel tiles
-
-    myfile.fit[compress R; q 10.0] - quantization level = (RMS-noise) / 10.
-    myfile.fit[compress HS; s 2.0]  -  HSCOMPRESS (with smoothing)
-                                          and scale = 2.0 * RMS-noise
-\end{verbatim}
-
-2)  Before calling the CFITSIO routine to write the image header
-keywords (e.g., fits\_create\_image) the programmer can call the
-routines described below to specify the compression algorithm and the
-tiling pattern that is to be used.  There are routines for specifying
-the various compression parameters and similar routines to
-return the current values of the parameters:
-\label{ffsetcomp}  \label{ffgetcomp}
-
-\begin{verbatim}
-  int fits_set_compression_type(fitsfile *fptr, int comptype, int *status)
-  int fits_set_tile_dim(fitsfile *fptr, int ndim, long *tilesize, int *status)
-  int fits_set_quantize_level(fitsfile *fptr, float qlevel, int *status)
-  int fits_set_hcomp_scale(fitsfile *fptr, float scale, int *status)
-  int fits_set_hcomp_smooth(fitsfile *fptr, int smooth, int *status)
-              Set smooth = 1 to apply smoothing when uncompressing the image
-
-  int fits_get_compression_type(fitsfile *fptr, int *comptype, int *status)
-  int fits_get_tile_dim(fitsfile *fptr, int ndim, long *tilesize, int *status)
-  int fits_get_quantize_level(fitsfile *fptr, float *level, int *status)
-  int fits_get_hcomp_scale(fitsfile *fptr, float *scale, int *status)
-  int fits_get_hcomp_smooth(fitsfile *fptr, int *smooth, int *status)
-\end{verbatim}
-4 symbolic constants are defined for use as the value of the
-`comptype' parameter:  GZIP\_1, RICE\_1, HCOMPRESS\_1 or PLIO\_1.
-Entering NULL for
-comptype will turn off the tile-compression and cause normal FITS
-images to be written.
-
-
-No special action is required by software when read tile-compressed images because
-all the CFITSIO routines that read normal uncompressed FITS images also
-transparently read images in the tile-compressed format;  CFITSIO essentially
-treats the binary table that contains the compressed tiles as if
-it were an IMAGE extension.
-
-
-The following 2 routines are available for compressing or
-or decompressing an image:
-
-\begin{verbatim}
-  int fits_img_compress(fitsfile *infptr, fitsfile *outfptr, int *status);
-  int fits_img_decompress (fitsfile *infptr, fitsfile *outfptr, int *status);
-\end{verbatim}
-Before calling the compression routine, the compression parameters must
-first be defined in one of the 2 way described in the previous paragraphs.
-There is also a routine to determine if the current HDU contains
-a tile compressed image (it returns 1 or 0):
-
-\begin{verbatim}
-  int fits_is_compressed_image(fitsfile *fptr, int *status);
-\end{verbatim}
-A small example program called 'imcopy' is included with CFITSIO that
-can be used to compress (or uncompress) any FITS image.  This
-program can be used to experiment with the various compression options
-on existing FITS images as shown in these examples:
-
-\begin{verbatim}
-1)  imcopy infile.fit 'outfile.fit[compress]'
-
-       This will use the default compression algorithm (Rice) and the
-       default tile size (row by row)
-
-2)  imcopy infile.fit 'outfile.fit[compress GZIP]'
-
-       This will use the GZIP compression algorithm and the default
-       tile size (row by row).  The allowed compression algorithms are
-       Rice, GZIP, and PLIO.  Only the first letter of the algorithm
-       name needs to be specified.
-
-3)  imcopy infile.fit 'outfile.fit[compress G 100,100]'
-
-       This will use the GZIP compression algorithm and 100 X 100 pixel
-       tiles.
-
-4)  imcopy infile.fit 'outfile.fit[compress R 100,100; q 10.0]'
-
-       This will use the Rice compression algorithm, 100 X 100 pixel
-       tiles, and quantization level = RMSnoise / 10.0 (assuming the
-       input image has a floating point data type).
-
-5)  imcopy infile.fit outfile.fit
-
-       If the input file is in tile-compressed format, then it will be
-       uncompressed to the output file.  Otherwise, it simply copies
-       the input image to the output image.
-
-6)  imcopy 'infile.fit[1001:1500,2001:2500]'  outfile.fit
-
-       This extracts a 500 X 500 pixel section of the much larger
-       input image (which may be in tile-compressed format).  The
-       output is a normal uncompressed FITS image.
-
-7)  imcopy 'infile.fit[1001:1500,2001:2500]'  outfile.fit.gz
-
-       Same as above, except the output file is externally compressed
-       using the gzip algorithm.
-
-\end{verbatim}
-
-\section{ASCII and Binary Table Routines}
-
-These routines perform read and write operations on columns of data in
-FITS ASCII or Binary tables.  Note that in the following discussions,
-the first row and column in a table is at position 1 not 0.
-
-Users should also read the following chapter on the CFITSIO iterator
-function which provides a more `object oriented' method of reading and
-writing table columns.  The iterator function is a little more
-complicated to use, but the advantages are that it usually takes less
-code to perform the same operation, and the resulting program often
-runs faster because the FITS files are read and written using the most
-efficient block size.
-
-
-\subsection{Create New Table}
-
-
-\begin{description}
-\item[1 ]Create a new ASCII or bintable table extension. If
-   the FITS file is currently empty then a dummy primary array will be
-   created before appending the table extension to it.  The tbltype
-   parameter defines the type of table and can have values of
-   ASCII\_TBL or BINARY\_TBL.  The naxis2 parameter gives the initial
-   number of rows to be created in the table, and should normally be
-   set = 0.  CFITSIO will automatically increase the size of the table
-   as additional rows are written.  A non-zero number of rows may be
-   specified to reserve space for that many rows, even if a fewer
-   number of rows will be written.  The tunit and extname parameters
-   are optional and a null pointer may be given if they are not
-   defined.  The FITS Standard recommends that only letters, digits,
-   and the underscore character be used in column names (the ttype
-   parameter) with no embedded spaces.  Trailing blank characters are
-   not significant.   \label{ffcrtb}
-\end{description}
-
-\begin{verbatim}
-  int fits_create_tbl / ffcrtb
-      (fitsfile *fptr, int tbltype, LONGLONG naxis2, int tfields, char *ttype[],
-       char *tform[], char *tunit[], char *extname, int *status)
-\end{verbatim}
-
-\subsection{Column Information Routines}
-
-
-\begin{description}
-\item[1 ]  Get the number of rows or columns in the current FITS table.
-     The number of rows is given by the NAXIS2 keyword and the
-     number of columns is given by the TFIELDS keyword in the header
-    of the table. \label{ffgnrw}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_num_rows / ffgnrw
-      (fitsfile *fptr, > long *nrows, int *status);
-
-  int fits_get_num_rowsll / ffgnrwll
-      (fitsfile *fptr, > LONGLONG *nrows, int *status);
-
-  int fits_get_num_cols / ffgncl
-      (fitsfile *fptr, > int *ncols, int *status);
-\end{verbatim}
-
-
-\begin{description}
-\item[2 ] Get the table column number (and name) of the column whose name
-matches an input template name.   If casesen  = CASESEN then the column
-name match will be case-sensitive, whereas if casesen = CASEINSEN then
-the case will be ignored.  As a general rule, the column names should
-be treated as case INsensitive.
-
-The input column name template may be either the exact name of the
-column to be searched for, or it may contain wild card characters (*,
-?, or \#), or it may contain the integer number of the desired column
-(with the first column = 1).  The `*' wild card character matches any
-sequence of characters (including zero characters) and the `?'
-character matches any single character.  The \# wildcard will match any
-consecutive string of decimal digits (0-9).  If more than one column
-name in the table matches the template string, then the first match is
-returned and the status value will be set to COL\_NOT\_UNIQUE  as a
-warning that a unique match was not found.  To find the other cases
-that match the template, call the routine again leaving the input
-status value equal to COL\_NOT\_UNIQUE and the next matching name will
-then be returned.  Repeat this process until a status =
-COL\_NOT\_FOUND  is returned.
-
-The FITS Standard recommends that only letters, digits, and the
-underscore character be used in column names (with no embedded
-spaces).  Trailing blank characters are not significant.

-      (fitsfile *fptr, int casesen, char *templt, > char *colname,
-       int *colnum, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Return the data type, vector repeat value, and the width in bytes
-    of a column in an ASCII or binary table.  Allowed values for the
-    data type in ASCII tables are:  TSTRING, TSHORT, TLONG, TFLOAT, and
-    TDOUBLE.  Binary tables also support these types: TLOGICAL, TBIT,
-    TBYTE, TCOMPLEX and TDBLCOMPLEX.  The negative of the data type code
-    value is returned if it is a variable length array column.  Note
-    that in the case of a 'J' 32-bit integer binary table column, this
-    routine will return data type = TINT32BIT (which in fact is
-    equivalent to TLONG).  With most current C compilers, a value in a
-    'J' column has the same size as an 'int' variable, and may not be
-    equivalent to a 'long' variable, which is 64-bits long on an
-    increasing number of compilers.
-
-    The 'repeat' parameter returns the vector repeat count on the binary
-    table TFORMn keyword value. (ASCII table columns always have repeat
-    = 1).  The 'width' parameter returns the width in bytes of a single
-    column element (e.g., a '10D' binary table column will have width =
-    8, an ASCII table 'F12.2' column will have width = 12, and a binary
-    table'60A' character string  column will have width = 60);  Note that
-    CFITSIO supports the local convention for specifying arrays of
-    fixed length strings within a binary table character column using
-    the syntax TFORM = 'rAw' where 'r' is the total number of characters
-    (= the width of the column) and 'w' is the width of a unit string
-    within the column.  Thus if the column has TFORM = '60A12' then this
-    means that each row of the table contains 5 12-character substrings
-    within the 60-character field, and thus in this case this routine will
-    return typecode = TSTRING, repeat = 60, and width = 12.  (The TDIMn
-    keyword may also be used to specify the unit string length; The pair
-    of keywords TFORMn = '60A' and TDIMn = '(12,5)'  would have the
-    same effect as TFORMn = '60A12').  The number
-    of substrings in any binary table character string field can be
-    calculated by (repeat/width).  A null pointer may be given for any of
-    the output parameters that are not needed.
-
-   The second routine, fit\_get\_eqcoltype is similar except that in
-   the case of scaled integer columns it returns the 'equivalent' data
-   type that is needed to store the scaled values, and not necessarily
-   the physical data type of the unscaled values as stored in the FITS
-   table.  For example if a '1I' column in a binary table has TSCALn =
-   1 and TZEROn = 32768, then this column effectively contains unsigned
-   short integer values, and thus the returned value of typecode will
-   be TUSHORT, not TSHORT.  Similarly, if a column has TTYPEn = '1I'
-   and TSCALn = 0.12, then the returned typecode
-  will be TFLOAT. \label{ffgtcl}

-\subsection{Routines to Edit Rows or Columns}
-
-
-\begin{description}
-\item[1 ] Insert or delete rows in an ASCII or binary table. When inserting rows
-    all the rows following row FROW are shifted down by NROWS rows;  if
-    FROW = 0 then the blank rows are inserted at the beginning of the
-    table.  Note that it is *not* necessary to insert rows in a table before
-    writing data to those rows (indeed, it would be inefficient to do so).
-    Instead one may simply write data to any row of the table, whether that
-    row of data already exists or not.
-
-    The first delete routine deletes NROWS consecutive rows
-    starting with row FIRSTROW.  The second delete routine takes an
-    input string that lists the rows or row ranges (e.g.,
-    '5-10,12,20-30'), whereas the third delete routine takes an input
-    integer array that specifies each individual row to be deleted. In
-    both latter cases, the input list of rows to delete must be sorted
-    in ascending order.  These routines update the NAXIS2 keyword to
-    reflect the new number of rows in the
-   table. \label{ffirow} \label{ffdrow} \label{ffdrws} \label{ffdrrg}
-\end{description}
-
-\begin{verbatim}
-  int fits_insert_rows / ffirow
-      (fitsfile *fptr, LONGLONG firstrow, LONGLONG nrows, > int *status)
-
-  int fits_delete_rows / ffdrow
-      (fitsfile *fptr, LONGLONG firstrow, LONGLONG nrows, > int *status)
-

-
-  int fits_delete_rowlistll / ffdrwsll
-      (fitsfile *fptr, LONGLONG *rowlist, LONGLONG nrows, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Insert or delete column(s) in an ASCII or binary
-    table.  When inserting, COLNUM specifies the column number that the
-    (first) new column should occupy in the table.  NCOLS specifies how
-    many columns are to be inserted. Any existing columns from this
-    position and higher are shifted over to allow room for the new
-    column(s).  The index number on all the following keywords will be
-    incremented or decremented if necessary to reflect the new position
-    of the column(s) in the table:  TBCOLn, TFORMn, TTYPEn, TUNITn,
-    TNULLn, TSCALn, TZEROn, TDISPn, TDIMn, TLMINn, TLMAXn, TDMINn,
-    TDMAXn, TCTYPn, TCRPXn, TCRVLn, TCDLTn, TCROTn,
-   and TCUNIn. \label{fficol} \label{fficls} \label{ffdcol}
-\end{description}
-
-\begin{verbatim}

-
-  int fits_delete_col / ffdcol(fitsfile *fptr, int colnum, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Copy a column from one HDU to another (or to the same HDU).  If
-    create\_col = TRUE, then a new column will be inserted in the output
-    table, at position `outcolumn', otherwise the existing output column will
-    be overwritten (in which case it must have a compatible data type).
-    If outcolnum is greater than the number of column in the table, then
-    the new column will be appended to the end of the table.
-    Note that the first column in a table is at colnum = 1.
-    The standard indexed keywords that related to the column (e.g., TDISPn,
-   TUNITn, TCRPXn, TCDLTn, etc.) will also be copied. \label{ffcpcl}
-\end{description}
-
-\begin{verbatim}

-       int create_col, > int *status);
-\end{verbatim}
-
-\begin{description}
-\item[4 ] Copy 'nrows' consecutive rows from one table to another, beginning
-    with row 'firstrow'.  These rows will be appended to any existing
-    rows in the output table.
-   Note that the first row in a table is at row = 1. \label{ffcprw}

-\end{verbatim}
-
-\begin{description}
-\item[5 ] Modify the vector length of a binary table column (e.g.,
-    change a column from TFORMn = '1E' to '20E').  The vector
-   length may be increased or decreased from the current value. \label{ffmvec}
-\end{description}

-      (fitsfile *fptr, int colnum, LONGLONG newveclen, > int *status)
-\end{verbatim}

-\subsection{Read and Write Column Data Routines}
-
-The following routines write or read data values in the current ASCII
-or binary table extension.  If a write operation extends beyond the
-current size of the table, then the number of rows in the table will
-automatically be increased and the NAXIS2 keyword value will be
-updated.  Attempts to read beyond the end of the table will result in
-an error.
-
-Automatic data type conversion is performed for numerical data types
-(only) if the data type of the column (defined by the TFORMn keyword)
-differs from the data type of the array in the calling routine.  ASCII and binary
-tables support the following data type values:  TSTRING, TBYTE, TSBYTE, TSHORT,
-TUSHORT, TINT, TUINT, TLONG, TLONGLONG, TULONG, TFLOAT, or TDOUBLE.
-Binary tables also support TLOGICAL (internally mapped to the `char'
-data type), TCOMPLEX, and TDBLCOMPLEX.
-
-Note that it is *not* necessary to insert rows in a table before
-writing data to those rows (indeed, it would be inefficient to do so).
-Instead, one may simply write data to any row of the table, whether that
-row of data already exists or not.
-
-Individual bits in a binary table 'X' or 'B' column may be read/written
-to/from a *char array by specifying the TBIT datatype.  The *char
-array will be interpreted as an array of logical TRUE (1) or FALSE (0)
-values that correspond to the value of each bit in the FITS 'X' or 'B' column.
-Alternatively, the values in a binary table 'X' column may be read/written
-8 bits at a time to/from an array of 8-bit integers by specifying the
-TBYTE datatype.
-
-Note that within the context of these routines, the TSTRING data type
-corresponds to a C 'char**' data type, i.e., a pointer to an array of
-pointers to an array of characters.  This is different from the keyword
-reading and writing routines where TSTRING corresponds to a C 'char*'
-data type, i.e., a single pointer to an array of characters.  When
-reading strings from a table, the char arrays obviously must have been
-allocated long enough to hold the whole FITS table string.
-
-Numerical data values are automatically scaled by the TSCALn and TZEROn
-keyword values (if they exist).
-
-In the case of binary tables with vector elements, the 'felem'
-parameter defines the starting element (beginning with 1, not 0) within
-the cell (a cell is defined as the intersection of a row and a column
-and may contain a single value or a vector of values).  The felem
-parameter is ignored when dealing with ASCII tables. Similarly, in the
-case of binary tables the 'nelements' parameter specifies the total
-number of vector values to be read or written (continuing on subsequent
-rows if required) and not the number of table cells.
-
-
-\begin{description}
-\item[1 ] Write elements into an ASCII or binary table column.
-\end{description}
-   The first routine simply writes the array of values to the FITS file
-   (doing data type conversion if necessary) whereas the second routine
-   will substitute the  appropriate FITS null value for all elements
-   which are equal to the input value of nulval (note that this
-   parameter gives the address of nulval, not the null value
-   itself).  For integer columns the FITS null value is defined by the
-   TNULLn keyword (an error is returned if the keyword doesn't exist).
-   For floating point columns  the special IEEE NaN (Not-a-Number)
-   value will be written into the FITS file.  If a null pointer is
-   entered for nulval, then the null value is ignored and this routine
-   behaves the same as the first routine.  The third routine
-   simply writes undefined pixel values to the column.  The fourth routine
-   fills every column in the table with null values, in the specified
-   rows (ignoring any columns that do not have a defined null value).
-   \label{ffpcl} \label{ffpcn} \label{ffpclu}
-
-\begin{verbatim}
-  int fits_write_col / ffpcl
-      (fitsfile *fptr, int datatype, int colnum, LONGLONG firstrow,
-       LONGLONG firstelem, LONGLONG nelements, DTYPE *array, > int *status)
-
-  int fits_write_colnull / ffpcn
-      (fitsfile *fptr, int datatype, int colnum, LONGLONG firstrow,
-      LONGLONG firstelem, LONGLONG nelements, DTYPE *array, DTYPE *nulval,
-      > int *status)

-
-   int fits_write_nullrows / ffprwu
-       (fitsfile *fptr, LONGLONG firstrow, LONGLONG nelements, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Read elements from an ASCII or binary table column.  The data type
-    parameter specifies the data type of the `nulval' and `array'  pointers;
-    Undefined array elements will be returned with a value = *nullval,
-    (note that this parameter gives the address of the null value, not the
-    null value itself) unless nulval = 0 or *nulval = 0, in which case
-    no checking for undefined pixels will be performed.  The second
-    routine is similar except that any undefined pixels will have the
-    corresponding nullarray element set equal to TRUE (= 1).
-
-    Any column, regardless of it's intrinsic data type, may be read as a
-    string.  It should be noted however that reading a numeric column
-    as a string is 10 - 100 times slower than reading the same column
-    as a number due to the large overhead in constructing the formatted
-    strings.  The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    data type of the column.  The length of the returned strings (not
-    including the null terminating character) can be determined with
-    the fits\_get\_col\_display\_width routine.  The following TDISPn
-    display formats are currently supported:
-
-\begin{verbatim}
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
-\end{verbatim}
-    where w is the width in characters of the displayed values, m is the minimum
-    number of digits displayed, and d is the number of digits to the right of the
-    decimal.  The .m field is optional.

-\subsection{Row Selection and Calculator Routines}
-
-These routines all parse and evaluate an input string containing a user
-defined arithmetic expression.  The first 3 routines select rows in a
-FITS table, based on whether the expression evaluates to true (not
-equal to zero) or false (zero).  The other routines evaluate the
-expression and calculate a value for each row of the table.  The
-allowed expression syntax is described in the row filter section in the
-`Extended File Name Syntax' chapter of this document.  The expression
-may also be written to a text file, and the name of the file, prepended
-with a '@' character may be supplied for the 'expr' parameter (e.g.
-'@filename.txt'). The  expression  in  the  file can be arbitrarily
-complex and extend over multiple lines of the file.  Lines  that begin
-with 2 slash characters ('//') will  be ignored and may be used to add
-comments to the file.
-
-
-\begin{description}

-\item[5 ]Evaluate an expression and write the result either to a column (if
-the expression is a function of other columns in the table) or to a
-keyword (if the expression evaluates to a constant and is not a

-parName parameter is the name of the column (which may or may not already
-exist) into which to write the results, and parInfo contains an
-optional TFORM keyword value if a new column is being created.  If a
-TFORM value is not specified then a default format will be used,
-depending on the expression.  If the expression evaluates to a constant,
-then the result will be written to the keyword name given by the
-parName parameter, and the parInfo parameter may be used to supply an
-optional comment for the keyword.  If the keyword does not already

-\subsection{Column Binning or Histogramming Routines}
-
-The following routines may be useful when performing histogramming operations on
-column(s) of a table to generate an image in a primary array or image extension.
-
-
-\begin{description}
-\item[1 ]  Calculate the histogramming parameters (min, max, and bin size
-for each axis of the histogram, based on a variety of possible input parameters.
-If the input names of the columns to be binned are null, then the routine will first
-look for the CPREF = "NAME1, NAME2, ..." keyword which lists the preferred
-columns.  If not present, then the routine will assume the column names X, Y, Z, and T
-for up to 4 axes (as specified by the NAXIS parameter).
-
-MININ and MAXIN are input arrays that give the minimum and maximum value for
-the histogram, along each axis.  Alternatively, the name of keywords that give
-the min, max, and binsize may be give with the MINNAME, MAXNAME, and BINNAME
-array parameters.  If the value = DOUBLENULLVALUE and no keyword names are
-given,  then the routine will use the TLMINn and TLMAXn keywords, if present, or the
-actual min and/or max values in the column.
-
-BINSIZEIN is an array giving the binsize along each axis.
-If the value =
-DOUBLENULLVALUE, and a keyword name is not specified with BINNAME,
-then this routine will first look for the TDBINn keyword, or else will
-use a binsize = 1, or a binsize that produces 10 histogram bins, which ever
-is smaller.

-\item[2 ] Copy the relevant keywords from the header of the table that is being
-binned, to the the header of the output histogram image.  This will not
-copy the table structure keywords (e.g., NAXIS, TFORMn, TTYPEn, etc.) nor
-will it copy the keywords that apply to other columns of the table that are
-not used to create the histogram.  This routine will translate the names of
-the World Coordinate System (WCS) keywords for the binned columns into the
-form that is need for a FITS image (e.g., the TCTYPn table keyword will
-be translated to the CTYPEn image keyword).

-\section{Utility Routines}
-
-
-\subsection{File Checksum Routines}
-
-The following routines either compute or validate the checksums for the
-CHDU.  The DATASUM keyword is used to store the numerical value of the
-32-bit, 1's complement checksum for the data unit alone.  If there is
-no data unit then the value is set to zero. The numerical value is
-stored as an ASCII string of digits, enclosed in quotes, because the
-value may be too large to represent as a 32-bit signed integer.  The
-CHECKSUM keyword is used to store the ASCII encoded COMPLEMENT of the
-checksum for the entire HDU.  Storing the complement, rather than the
-actual checksum, forces the checksum for the whole HDU to equal zero.
-If the file has been modified since the checksums were computed, then
-the HDU checksum will usually not equal zero.  These checksum keyword
-conventions are based on a paper by Rob Seaman published in the
-proceedings of the ADASS IV conference in Baltimore in November 1994
-and a later revision in June 1995.  See Appendix B for the definition
-of the parameters used in these routines.
-
-
-\begin{description}
-\item[1 ] Compute and write the DATASUM and CHECKSUM keyword values for the CHDU
-    into the current header.  If the keywords already exist, their values
-    will be updated only if necessary (i.e., if the file
-    has been modified since the original keyword
-   values were computed). \label{ffpcks}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_chksum / ffpcks
-      (fitsfile *fptr, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Update the CHECKSUM keyword value in the CHDU, assuming that the
-    DATASUM keyword exists and already has the correct value.  This routine
-    calculates the new checksum for the current header unit, adds it to the
-    data unit checksum, encodes the value into an ASCII string, and writes
-   the string to the CHECKSUM keyword. \label{ffupck}
-\end{description}
-
-\begin{verbatim}
-  int fits_update_chksum / ffupck
-      (fitsfile *fptr, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Verify the CHDU by computing the checksums and comparing
-    them with the keywords.  The data unit is verified correctly
-    if the computed checksum equals the value of the DATASUM
-    keyword.  The checksum for the entire HDU (header plus data unit) is
-    correct if it equals zero.  The output DATAOK and HDUOK parameters
-    in this routine are integers which will have a value = 1
-    if the data or HDU is verified correctly, a value = 0
-    if the DATASUM or CHECKSUM keyword is not present, or value = -1
-   if the computed checksum is not correct. \label{ffvcks}
-\end{description}
-
-\begin{verbatim}
-  int fits_verify_chksum / ffvcks
-      (fitsfile *fptr, > int *dataok, int *hduok, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ] Compute and return the checksum values for the CHDU
-    without creating or modifying the
-    CHECKSUM and DATASUM keywords.  This routine is used internally by
-   ffvcks, but may be useful in other situations as well. \label{ffgcks}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_chksum/ /ffgcks
-      (fitsfile *fptr, > unsigned long *datasum, unsigned long *hdusum,
-       int *status)
-\end{verbatim}
-
-\begin{description}
-\item[5 ] Encode a checksum value
-    into a 16-character string.  If complm is non-zero (true) then the 32-bit
-   sum value will be complemented before encoding. \label{ffesum}
-\end{description}
-
-\begin{verbatim}
-  int fits_encode_chksum / ffesum
-      (unsigned long sum, int complm, > char *ascii);
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Decode a 16-character checksum string into a unsigned long value.
-    If is non-zero (true). then the 32-bit sum value will be complemented
-    after decoding.  The checksum value is also returned as the
-   value of the function. \label{ffdsum}
-\end{description}
-
-\begin{verbatim}
-  unsigned long fits_decode_chksum / ffdsum
-           (char *ascii, int complm, > unsigned long *sum);
-\end{verbatim}
-
-
-\subsection{Date and Time Utility Routines}
-
-The following routines help to construct or parse the FITS date/time
-strings.   Starting in the year 2000, the FITS DATE keyword values (and
-the values of other `DATE-' keywords) must have the form 'YYYY-MM-DD'
-(date only) or 'YYYY-MM-DDThh:mm:ss.ddd...' (date and time) where the
-number of decimal places in the seconds value is optional.  These times
-are in UTC.  The older 'dd/mm/yy' date format may not be used for dates
-after 01 January 2000.  See Appendix B for the definition of the
-parameters used in these routines.
-
-
-\begin{description}
-\item[1 ] Get the current system date.  C already provides standard
-    library routines for getting the current date and time,
-    but this routine is provided for compatibility with
-    the Fortran FITSIO library.  The returned year has 4 digits
-    (1999, 2000, etc.) \label{ffgsdt}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_system_date/ffgsdt
-      ( > int *day, int *month, int *year, int *status )
-\end{verbatim}
-
-
-\begin{description}
-\item[2 ] Get the current system date and time string ('YYYY-MM-DDThh:mm:ss').
-The time will be in UTC/GMT if available, as indicated by a returned timeref
-value = 0.  If the returned value of timeref = 1 then this indicates that
-it was not possible to convert the local time to UTC, and thus the local
-time was returned.
-\end{description}
-
-\begin{verbatim}
-  int fits_get_system_time/ffgstm
-      (> char *datestr, int  *timeref, int *status)
-\end{verbatim}
-
-
-\begin{description}
-\item[3 ] Construct a date string from the input date values.  If the year
-is between 1900 and 1998, inclusive, then the returned date string will
-have the old FITS format ('dd/mm/yy'), otherwise the date string will
-have the new FITS format ('YYYY-MM-DD').  Use fits\_time2str instead
- to always return a date string using the new FITS format. \label{ffdt2s}
-\end{description}
-
-\begin{verbatim}
-  int fits_date2str/ffdt2s
-      (int year, int month, int day, > char *datestr, int *status)
-\end{verbatim}
-
-
-\begin{description}
-\item[4 ] Construct a new-format date + time string ('YYYY-MM-DDThh:mm:ss.ddd...').
-  If the year, month, and day values all = 0 then only the time is encoded
-  with format 'hh:mm:ss.ddd...'.  The decimals parameter specifies how many
-  decimal places of fractional seconds to include in the string.  If `decimals'
- is negative, then only the date will be return ('YYYY-MM-DD').
-\end{description}
-
-\begin{verbatim}
-  int fits_time2str/fftm2s
-      (int year, int month, int day, int hour, int minute, double second,
-      int decimals, > char *datestr, int *status)
-\end{verbatim}
-
-
-\begin{description}
-\item[5 ] Return the date as read from the input string, where the string may be
-in either the old ('dd/mm/yy')  or new ('YYYY-MM-DDThh:mm:ss' or
-'YYYY-MM-DD') FITS format.  Null pointers may be supplied for any
-  unwanted output date parameters.
-\end{description}
-
-\begin{verbatim}
-  int fits_str2date/ffs2dt
-      (char *datestr, > int *year, int *month, int *day, int *status)
-\end{verbatim}
-
-
-\begin{description}
-\item[6 ] Return the date and time as read from the input string, where the
-string may be in either the old  or new FITS format.  The returned hours,
-minutes, and seconds values will be set to zero if the input string
-does not include the time ('dd/mm/yy' or 'YYYY-MM-DD') .  Similarly,
-the returned year, month, and date values will be set to zero if the
-date is not included in the input string ('hh:mm:ss.ddd...').  Null
-pointers may be supplied for any unwanted output date and time
-parameters.
-\end{description}
-
-\begin{verbatim}
-  int fits_str2time/ffs2tm
-      (char *datestr, > int *year, int *month, int *day, int *hour,
-      int *minute, double *second, int *status)
-\end{verbatim}
-
-
-\subsection{General Utility Routines}
-
-The following utility routines may be useful for certain applications.
-
-
-\begin{description}
-\item[1 ] Return the revision number of the CFITSIO library.
-    The revision number will be incremented with each new
-   release of CFITSIO. \label{ffvers}
-\end{description}
-
-\begin{verbatim}
-  float fits_get_version / ffvers ( > float *version)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Write an 80-character message to the CFITSIO error stack.  Application
-    programs should not normally write to the stack, but there may be
-   some situations where this is desirable. \label{ffpmsg}
-\end{description}
-
-\begin{verbatim}
-  void fits_write_errmsg / ffpmsg (char *err_msg)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Convert a character string to uppercase (operates in place). \label{ffupch}
-\end{description}
-
-\begin{verbatim}
-  void fits_uppercase / ffupch (char *string)
-\end{verbatim}
-
-\begin{description}
-\item[4 ] Compare the input template string against the reference string
-    to see if they match.  The template string may contain wildcard
-    characters: '*' will match any sequence of characters (including
-    zero characters) and '?' will match any single character in the
-    reference string.  The '\#' character will match any consecutive string
-    of decimal digits (0 - 9).  If casesen = CASESEN = TRUE then the match will
-    be case sensitive, otherwise the case of the letters will be ignored
-    if casesen = CASEINSEN = FALSE.  The returned MATCH parameter will be
-    TRUE if the 2 strings match, and EXACT will be TRUE if the match is
-    exact (i.e., if no wildcard characters were used in the match).
-   Both strings must be 68 characters or less in length. \label{ffcmps}
-\end{description}
-
-\begin{verbatim}
-  void fits_compare_str / ffcmps
-       (char *templt, char *string, int casesen, > int *match, int *exact)
-\end{verbatim}
-
-\begin{description}
-\item[5 ]Split a string containing a list of names (typically file names or column
-   names) into individual name tokens by a sequence of calls to
-   fits\_split\_names.  The names in the list must be delimited by a comma
-   and/or spaces.  This routine ignores spaces and commas that occur
-   within parentheses, brackets, or curly brackets.  It also strips any
-   leading and trailing blanks from the returned name.
-
-   This routine is similar to the ANSI C 'strtok' function:
-
-   The first call to fits\_split\_names has a non-null input string.
-   It finds the first name in the string and terminates it by overwriting
-   the next character of the string with a null terminator and returns a
-   pointer to the name.  Each subsequent call, indicated by a NULL value
-   of the input string, returns the next name, searching from just past
-   the end of the previous name.  It returns NULL when no further names
-  are found.  \label{splitnames}
-\end{description}
-
-\begin{verbatim}
-   char *fits_split_names(char *namelist)
-\end{verbatim}
-   The following example shows how a string would be split into 3 names:
-
-\begin{verbatim}
-    myfile[1][bin (x,y)=4], file2.fits  file3.fits
-    ^^^^^^^^^^^^^^^^^^^^^^  ^^^^^^^^^^  ^^^^^^^^^^
-        1st name             2nd name    3rd name
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Test that the keyword name contains only legal characters (A-Z,0-9,
-    hyphen, and underscore) or that the keyword record contains only legal
-   printable ASCII characters  \label{fftkey} \label{fftrec}
-\end{description}
-
-\begin{verbatim}
-  int fits_test_keyword / fftkey (char *keyname, > int *status)
-
-  int fits_test_record / fftrec (char *card, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[7 ] Test whether the current header contains any NULL (ASCII 0) characters.
-    These characters are illegal in the header, but they will go undetected
-    by most of the CFITSIO keyword header routines, because the null is
-    interpreted as the normal end-of-string terminator.  This routine returns
-    the position of the first null character in the header, or zero if there
-    are no nulls.  For example a returned value of 110 would indicate that
-    the first NULL is located in the 30th character of the second keyword
-    in the header (recall that each header record is 80 characters long).
-    Note that this is one of the few CFITSIO routines in which the returned
-    value is not necessarily equal to the status value).   \label{ffnchk}
-\end{description}
-
-\begin{verbatim}
-  int fits_null_check / ffnchk (char *card, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[8 ] Parse a header keyword record and return the name of the keyword,
-    and the length of the name.
-    The keyword name normally occupies the first 8 characters of the
-    record, except under the HIERARCH convention where the name can
-   be up to 70 characters in length. \label{ffgknm}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_keyname / ffgknm
-      (char *card, > char *keyname, int *keylength, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[9 ] Parse a header keyword record, returning the value (as
-    a literal character string) and comment strings.  If the keyword has no
-    value (columns 9-10 not equal to '= '), then a null value string is
-    returned and the comment string is set equal to column 9 - 80 of the
-   input string. \label{ffpsvc}
-\end{description}
-
-\begin{verbatim}
-  int fits_parse_value / ffpsvc
-      (char *card, > char *value, char *comment, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[10] Construct an array indexed keyword name (ROOT + nnn).
-    This routine appends the sequence number to the root string to create
-   a keyword name (e.g., 'NAXIS' + 2 = 'NAXIS2') \label{ffkeyn}
-\end{description}
-
-\begin{verbatim}
-  int fits_make_keyn / ffkeyn
-      (char *keyroot, int value, > char *keyname, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[11]  Construct a sequence keyword name (n + ROOT).
-    This routine concatenates the sequence number to the front of the
-   root string to create a keyword name (e.g., 1 + 'CTYP' = '1CTYP') \label{ffnkey}
-\end{description}
-
-\begin{verbatim}
-  int fits_make_nkey / ffnkey
-      (int value, char *keyroot, > char *keyname, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[12] Determine the data type of a keyword value string. This routine
-    parses the keyword value string  to determine its data type.
-    Returns 'C', 'L', 'I', 'F' or 'X', for character string, logical,
-   integer, floating point, or complex, respectively. \label{ffdtyp}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_keytype / ffdtyp
-      (char *value, > char *dtype, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[13] Determine the integer data type of an integer keyword value string.
-   The returned datatype value is the minimum integer datatype (starting
-   from top of the following list and working down) required
-  to store the integer value:
-\end{description}
-
-\begin{verbatim}
-    Data Type      Range
-     TSBYTE:     -128 to 127
-     TBYTE:       128 to 255
-     TSHORT:     -32768 to 32767
-     TUSHORT:     32768 to 65535

-     TLONGLONG   -9223372036854775808 to 9223372036854775807
-\end{verbatim}
-
-\begin{description}
-\item[  ]  The *neg parameter returns 1 if the input value is
-    negative and returns 0 if it is non-negative.\label{ffinttyp}
-\end{description}

-\begin{verbatim}
-  int fits_get_inttype / ffinttyp
-      (char *value, > int *datatype, int *neg, int *status)
-\end{verbatim}
-
-\begin{description}
-\item[14] Return the class of an input header record.  The record is classified
-    into one of the following categories (the class values are
-    defined in fitsio.h).  Note that this is one of the few CFITSIO
-   routines that does not return a status value. \label{ffgkcl}

-    suitable for appending to (or deleting from) a FITS header file.
-    This routine is useful for parsing lines from an ASCII template file
-    and reformatting them into legal FITS header records.  The formatted
-    string may then be passed to the fits\_write\_record, ffmcrd, or
-    fits\_delete\_key routines
-   to append or modify a FITS header record. \label{ffgthd}
-\end{description}
-
-\begin{verbatim}
-  int fits_parse_template / ffgthd
-      (char *templt, > char *card, int *keytype, int *status)
-\end{verbatim}
-    The input templt character string generally should contain 3 tokens:
-    (1) the KEYNAME, (2) the VALUE, and (3) the COMMENT string.  The
-    TEMPLATE string must adhere to the following format:
-
-
-\begin{description}
-\item[- ]     The KEYNAME token must begin in columns 1-8 and be a maximum  of 8
-        characters long.  A legal FITS keyword name may only
-        contain the characters A-Z, 0-9, and '-' (minus sign) and
-        underscore.  This routine will automatically convert any lowercase
-        characters to uppercase in the output string.  If the first 8 characters
-        of the template line are
-        blank then the remainder of the line is considered to be a FITS comment
-       (with a blank keyword name).
-\end{description}
-
-
-\begin{description}
-\item[- ]     The VALUE token must be separated from the KEYNAME token by one or more
-        spaces and/or an '=' character.  The data type of the VALUE token
-        (numeric, logical, or character string) is automatically determined
-        and  the output CARD string is formatted accordingly.  The value
-        token may be forced to be interpreted as a string (e.g. if it is a
-        string of numeric digits) by enclosing it in single quotes.
-        If the value token is a character string that contains 1 or more
-        embedded blank space characters or slash ('/') characters then the
-       entire character string must be enclosed in single quotes.
-\end{description}
-
-
-\begin{description}
-\item[- ]     The COMMENT token is optional, but if present must be separated from
-       the VALUE token by a blank space or a  '/' character.
-\end{description}
-
-
-\begin{description}
-\item[- ]     One exception to the above rules is that if the first non-blank
-        character in the first 8 characters of the template string is a
-        minus sign ('-') followed
-        by a single token, or a single token followed by an equal sign,
-        then it is interpreted as the name of a keyword which is to be
-       deleted from the FITS header.
-\end{description}
-
-
-\begin{description}
-\item[- ]     The second exception is that if the template string starts with
-        a minus sign and is followed by 2 tokens (without an equals sign between
-        them) then the second token
-        is interpreted as the new name for the keyword specified by
-        first token.  In this case the old keyword name (first token)
-        is returned in characters 1-8 of the returned CARD string, and
-        the new keyword name (the second token) is returned in characters
-        41-48 of the returned CARD string.  These old and new names
-        may then be passed to the ffmnam routine which will change
-       the keyword name.
-\end{description}
-
-    The keytype output parameter indicates how the returned CARD string
-    should be interpreted:
-
-\begin{verbatim}
-        keytype                  interpretation
-        -------          -------------------------------------------------
-           -2            Rename the keyword with name = the first 8 characters of CARD
-                         to the new name given in characters 41 - 48 of CARD.
-
-           -1            delete the keyword with this name from the FITS header.
-
-            0            append the CARD string to the FITS header if the
-                         keyword does not already exist, otherwise update
-                         the keyword value and/or comment field if is already exists.
-
-            1            This is a HISTORY or COMMENT keyword; append it to the header
-
-            2            END record; do not explicitly write it to the FITS file.
-\end{verbatim}
-     EXAMPLES:  The following lines illustrate valid input template strings:
-
-\begin{verbatim}
-      INTVAL 7 / This is an integer keyword
-      RVAL           34.6   /     This is a floating point keyword
-      EVAL=-12.45E-03  / This is a floating point keyword in exponential notation
-      lval F / This is a boolean keyword
-                  This is a comment keyword with a blank keyword name
-      SVAL1 = 'Hello world'   /  this is a string keyword
-      SVAL2  '123.5'  this is also a string keyword
-      sval3  123+  /  this is also a string keyword with the value '123+    '
-      # the following template line deletes the DATE keyword
-      - DATE
-      # the following template line modifies the NAME keyword to OBJECT
-      - NAME OBJECT
-\end{verbatim}

-\begin{description}
-\item[19]  Translate a keyword name into a new name, based on a set of patterns.
-This routine is useful for translating keywords in cases such as
-adding or deleting columns in
-a table, or copying a column from one table to another, or extracting
-an array from a cell in a binary table column into an image extension.  In
-these cases, it is necessary to translate the names of the keywords associated
-with the original table column(s) into the appropriate keyword name in the final
-file.  For example, if column 2 is deleted from a table,
-then the value of 'n' in all the
-TFORMn and TTYPEn keywords for columns 3 and higher must be decremented
-by 1.  Even more complex translations are sometimes needed to convert the
-WCS keywords when extracting an image out of a table column cell into
-a separate image extension.
-
-The user passes an array of patterns to be matched.  Input pattern
-number i is pattern[i][0], and output pattern number i is
-pattern[i][1].  Keywords are matched against the input patterns.  If a
-match is found then the keyword is re-written according to the output
-pattern.
-
-Order is important.  The first match is accepted.  The fastest match
-will be made when templates with the same first character are grouped
-together.
-
-Several characters have special meanings:
-
-\begin{verbatim}
-     i,j - single digits, preserved in output template
-     n - column number of one or more digits, preserved in output template
-     m - generic number of one or more digits, preserved in output template
-     a - coordinate designator, preserved in output template
-     # - number of one or more digits
-     ? - any character
-     * - only allowed in first character position, to match all
-         keywords; only useful as last pattern in the list
-\end{verbatim}
-i, j, n, and m are returned by the routine.
-
-For example, the input pattern "iCTYPn" will match "1CTYP5" (if n\_value
-is 5); the output pattern "CTYPEi" will be re-written as "CTYPE1".
-Notice that "i" is preserved.
-
-The following output patterns are special:
-
-    "-" - do not copy a keyword that matches the corresponding input pattern
-
-    "+" - copy the input unchanged
-
-The inrec string could be just the 8-char keyword name, or the entire
-80-char header record.  Characters 9 - 80 in the input string simply get
-appended to the translated keyword name.
-
-If n\_range = 0, then only keywords with 'n' equal to n\_value will be
-considered as a pattern match.  If n\_range = +1, then all values of
-'n' greater than or equal to n\_value will be a match, and if -1,
-then values of 'n' less than or equal to n\_value will match.\label{translatekey}

-\chapter{  The CFITSIO Iterator Function }
-
-The fits\_iterate\_data function in CFITSIO provides a unique method of
-executing an arbitrary user-supplied `work' function that operates on
-rows of data in  FITS tables or on pixels in FITS images.  Rather than
-explicitly reading and writing the FITS images or columns of data, one
-instead calls the CFITSIO iterator routine, passing to it the name of
-the user's work function that is to be executed along with a list of
-all the table columns or image arrays that are to be passed to the work
-function.  The CFITSIO iterator function then does all the work of
-allocating memory for the arrays, reading the input data from the FITS
-file, passing them to the work function, and then writing any output
-data back to the FITS file after the work function exits.  Because
-it is often more efficient to process only a subset of the total table
-rows at one time, the iterator function can determine the optimum
-amount of data to pass in each iteration and repeatedly call the work
-function until the entire table been processed.
-
-For many applications this single CFITSIO iterator function can
-effectively replace all the other CFITSIO routines for reading or
-writing data in FITS images or tables.  Using the iterator has several
-important advantages over the traditional method of reading and writing
-FITS data files:
-
-\begin{itemize}
-\item
-It cleanly separates the data I/O from the routine that operates on
-the data.  This leads to a more modular and `object oriented'
-programming style.
-
-\item
-It simplifies the application program by eliminating the need to allocate
-memory for the data arrays and eliminates most of the calls to the CFITSIO
-routines that explicitly read and write the data.
-
-\item
-It ensures that the data are processed as efficiently as possible.
-This is especially important when processing tabular data since
-the iterator function will calculate the most efficient number
-of rows in the table to be passed at one time to the user's work
-function on each iteration.
-
-\item
-Makes it possible for larger projects to develop a library of work
-functions that all have a uniform calling sequence and are all
-independent of the details of the FITS file format.
-
-\end{itemize}
-
-There are basically 2 steps in using the CFITSIO iterator function.
-The first step is to design the work function itself which must have a
-prescribed set of input parameters.  One of these parameters is a
-structure containing pointers to the arrays of data; the work function
-can perform any desired operations on these arrays and does not need to
-worry about how the input data were read from the file or how the
-output data get written back to the file.
-
-The second step is to design the driver routine that opens all the
-necessary FITS files and initializes  the input parameters to the
-iterator function.  The driver program calls the CFITSIO iterator
-function which then reads the data and passes it to the user's work
-function.
-
-The following 2 sections describe these steps in more detail.  There
-are also several example programs included with the CFITSIO
-distribution which illustrate how to use the iterator function.
-
-
-\section{The Iterator Work Function}
-
-The user-supplied iterator work function must have the following set of
-input parameters (the function can be given any desired name):
-
-
-\begin{verbatim}
-  int user_fn( long totaln, long offset, long firstn, long nvalues,
-               int narrays, iteratorCol *data,  void *userPointer )
-\end{verbatim}
-
-\begin{itemize}
-
-\item
-  totaln -- the total number of table rows or image pixels
-            that will be passed to the work function
-            during 1 or more iterations.
-
-\item
-  offset     -- the offset applied to the first table row or image
-                pixel to be passed to the work function.  In other
-                words, this is the number of rows or pixels that
-                are skipped over before starting the iterations. If
-                offset = 0, then all the table rows or image pixels
-                will be passed to the work function.
-
-\item
-  firstn     -- the number of the first table row or image pixel
-                (starting with 1)  that is being passed in this
-                particular call to the work function.
-
-\item
-  nvalues    -- the number of table rows or image pixels that are
-                being passed in this particular call to the work
-                function.  nvalues will always be less than or
-                equal to totaln and will have the same value on
-                each iteration, except possibly on the last
-                call which may have a smaller value.
-
-\item
-  narrays     -- the number of arrays of data that are being passed
-                 to the work function.  There is one array for each
-                 image or table column.
-
-\item
-  *data   -- array of structures, one for each
-             column or image.  Each structure contains a pointer
-             to the array of data as well as other descriptive
-             parameters about that array.
-
-\item
-  *userPointer -- a user supplied pointer that can be used
-                 to pass ancillary information from the driver function
-                 to the work function.
-                 This pointer is passed to the CFITSIO iterator function
-                 which then passes it on to the
-                 work function without any modification.
-                 It may point to a single number, to an array of values,
-                 to a structure containing an arbitrary set of parameters
-                 of different types,
-                 or it may be a null pointer if it is not needed.
-                 The work function must cast this pointer to the
-                 appropriate data type before using it it.
-\end{itemize}
-
-The totaln, offset, narrays, data, and userPointer parameters are
-guaranteed to have the same value on each iteration.  Only firstn,
-nvalues, and the arrays of data pointed to by the data structures may
-change on each iterative call to the work function.
-
-Note that the iterator treats an image as a long 1-D array of pixels
-regardless of it's intrinsic dimensionality.  The total number of
-pixels is just the product of the size of each dimension, and the order
-of the pixels is the same as the order that they are stored in the FITS
-file. If the work function needs to know the number and size of the
-image dimensions then these parameters can be passed via the
-userPointer structure.
-
-The iteratorCol structure is currently defined as follows:
-
-\begin{verbatim}
-typedef struct  /* structure for the iterator function column information */
-{
-   /* structure elements required as input to fits_iterate_data: */
-
-  fitsfile *fptr;       /* pointer to the HDU containing the column or image */
-  int      colnum;      /* column number in the table; ignored for images    */
-  char     colname[70]; /* name (TTYPEn) of the column; null for images      */
-  int      datatype;    /* output data type (converted if necessary) */
-  int      iotype;      /* type: InputCol, InputOutputCol, or OutputCol */
-
-  /* output structure elements that may be useful for the work function: */
-
-  void     *array;    /* pointer to the array (and the null value) */
-  long     repeat;    /* binary table vector repeat value; set     */

-\end{verbatim}
-
-Instead of directly reading or writing the elements in this structure,
-it is recommended that programmers use the access functions that are
-provided for this purpose.
-
-The first five elements in this structure must be initially defined by
-the driver routine before calling the iterator routine.  The CFITSIO
-iterator routine uses this information to determine what column or
-array to pass to the work function, and whether the array is to be
-input to the work function, output from the work function, or both.
-The CFITSIO iterator function fills in the values of the remaining
-structure elements before passing it to the work function.
-
-The array structure element is a pointer to the actual data array and
-it must be cast to the correct data type before it is used.  The
-`repeat' structure element give the number of data values in each row
-of the table, so that the total number of data values in the array is
-given by repeat * nvalues.  In the case of image arrays and ASCII
-tables, repeat will always be equal to 1.  When the data type is a
-character string, the array pointer is actually a pointer to an array
-of string pointers (i.e., char **array).  The other output structure
-elements are provided for convenience in case that information is
-needed within the work function.  Any other information may be passed
-from the driver routine to the work function via the userPointer
-parameter.
-
-Upon completion, the work routine must return an integer status value,
-with 0 indicating success and any other value indicating an error which
-will cause the iterator function to immediately exit at that point.  Return status
-values in the range 1 -- 1000 should be avoided since these are
-reserved for use by CFITSIO.  A return status value of -1 may be used to
-force the CFITSIO iterator function to stop at that point and return
-control to the driver routine after writing any output arrays to the
-FITS file.  CFITSIO does not considered this to be an error condition,
-so any further processing by the application program will continue normally.
-
-
-\section{The Iterator Driver Function}
-
-The iterator driver function must open the necessary FITS files and
-position them to the correct HDU.  It must also initialize the following
-parameters in the iteratorCol structure (defined above) for each
-column or image before calling the CFITSIO iterator function.
-Several `constructor' routines are provided in CFITSIO for this
-purpose.
-
-\begin{itemize}
-\item
-  *fptr --  The fitsfile pointer to the table or image.
-\item
-colnum -- the number of the column in the table.  This value is ignored
-          in the case of images.  If colnum equals 0, then the column name
-          will be used to identify the column to be passed to the
-          work function.
-
-\item
-colname -- the name (TTYPEn keyword) of the column.  This is
-           only required if colnum = 0 and is ignored for images.
-\item
-datatype -- The desired data type of the array to be passed to the
-            work function.  For numerical data the data type does
-            not need to be the same as the actual data type in the
-            FITS file, in which case CFITSIO will do the conversion.
-            Allowed values are: TSTRING, TLOGICAL, TBYTE, TSBYTE, TSHORT, TUSHORT,
-            TINT, TLONG, TULONG, TFLOAT, TDOUBLE.  If the input
-            value of data type equals 0, then the  existing
-            data type of the column or image will be used without
-            any conversion.
-
-\item
-iotype -- defines whether the data array is to be input to the
-          work function (i.e, read from the FITS file), or output
-          from the work function (i.e., written to the FITS file) or
-          both.  Allowed values are InputCol, OutputCol, or InputOutputCol.
-	  Variable-length array columns are supported as InputCol or
-	  InputOutputCol types, but may not be used for an OutputCol type.
-\end{itemize}
-
-After the driver routine has initialized all these parameters, it
-can then call the CFITSIO iterator function:
-
-
-\begin{verbatim}
-  int fits_iterate_data(int narrays, iteratorCol *data, long offset,
-      long nPerLoop, int (*workFn)( ), void *userPointer, int *status);
-\end{verbatim}
-
-\begin{itemize}
-\item
-
-   narrays    -- the number of columns or images that are to be passed
-                 to the work function.
-\item
-   *data --     pointer to array of structures containing information
-                about each column or image.
-
-\item
-   offset      -- if positive, this number of rows at the
-                      beginning of the table (or pixels in the image)
-                      will be skipped and will not be passed to the work
-                      function.
-
-\item
-   nPerLoop   - specifies the number of table rows (or number of
-                    image pixels) that are to be passed to the work
-                    function on each iteration.  If nPerLoop = 0
-                    then CFITSIO will calculate the optimum number
-                    for greatest efficiency.
-                    If nPerLoop is negative, then all the rows
-                    or pixels will be passed at one time, and the work
-                    function will only be called once.  If any variable
-		    length arrays are being processed, then the nPerLoop
-		    value is ignored, and the iterator will always process
-		    one row of the table at a time.
-
-\item
-   *workFn     - the name (actually the address) of the work function
-                 that is to be called by fits\_iterate\_data.
-
-\item
-   *userPointer - this is a user supplied pointer that can be used
-                  to pass ancillary information from the driver routine
-                  to the work function.  It may point to a single number,
-                  an array, or to a structure containing an arbitrary set
-                  of parameters.
-
-\item
-   *status      - The CFITSIO error status.  Should = 0 on input;
-                  a non-zero output value indicates an error.
-\end{itemize}
-
-When fits\_iterate\_data is called it first allocates memory to hold
-all the requested columns of data or image pixel arrays.  It then reads
-the input data from the FITS tables or images into the arrays then
-passes the structure with pointers to these data arrays to the work
-function.  After the work function returns, the iterator function
-writes any output columns of data or images back to the FITS files.  It
-then repeats this process for any remaining sets of rows or image
-pixels until it has processed the entire table or image or until the
-work function returns a non-zero status value.  The iterator then frees
-the memory that it initially allocated and returns control to the
-driver routine that called it.
-
-
-\section{Guidelines for Using the Iterator Function}
-
-The totaln, offset, firstn, and nvalues parameters that are passed to
-the work function are useful for determining how much of the data has
-been processed and how much remains left to do.  On the very first call
-to the work function firstn will be equal to offset + 1;  the work
-function may need to perform various initialization tasks before
-starting to  process the data. Similarly, firstn + nvalues - 1 will be
-equal to totaln on the last iteration, at which point the work function
-may need to perform some clean up operations before exiting for the
-last time.  The work function can also force an early termination of
-the iterations by returning a status value = -1.
-
-The narrays and iteratorCol.datatype arguments allow the work function
-to double check that the number of input arrays and their data types
-have the expected values.  The iteratorCol.fptr and iteratorCol.colnum
-structure elements can be used if the work function needs to read or
-write the values of other keywords in the FITS file associated with
-the array.  This should generally only be done during the
-initialization step or during the clean up step after the last set of
-data has been processed.  Extra FITS file I/O during the main
-processing loop of the work function can seriously degrade the speed of
-the program.
-
-If variable-length array columns are being processed, then the iterator
-will operate on one row of the table at a time.  In this case the
-the repeat element in the interatorCol structure will be set equal to
-the number of elements in the current row that is being processed.
-
-One important feature of the iterator is that the first element in each
-array that is passed to the work function gives the value that is used
-to represent null or undefined values in the array.  The real data then
-begins with the second element of the array (i.e., array[1], not
-array[0]).  If the first array element is equal to zero, then this
-indicates that all the array elements have defined values and there are
-no undefined values.  If array[0] is not equal to zero, then this
-indicates that some of the data values are undefined and this value
-(array[0]) is used to represent them.  In the case of output arrays
-(i.e., those arrays that will be written back to the FITS file by the
-iterator function after the work function exits) the work function must
-set the first array element to the desired null value if necessary,
-otherwise the first element should be set to zero to indicate that
-there are no null values in the output array.  CFITSIO defines 2
-values, FLOATNULLVALUE and DOUBLENULLVALUE, that can be used as default
-null values for float and double data types, respectively.  In the case
-of character string data types, a null string is always used to
-represent undefined strings.
-
-In some applications it may be necessary to recursively call the iterator
-function.  An example of this is given by one of the example programs
-that is distributed with CFITSIO: it first calls a work function that
-writes out a 2D histogram image.  That work function in turn calls
-another work function that reads the  `X' and `Y' columns in a table to
-calculate the value of each 2D histogram image pixel. Graphically, the
-program structure can be described as:
-
-\begin{verbatim}
- driver --> iterator --> work1_fn --> iterator --> work2_fn
-\end{verbatim}
-
-Finally, it should be noted that the table columns or image arrays that
-are passed to the work function do not all have to come from the same
-FITS file and instead may come from any combination of sources as long
-as they have the same length.   The length of the first table column or
-image array is used by the iterator if they do not all have the same
-length.
-

-All of the iterator routines are listed below.  Most of these routines
-do not have a corresponding short function name.
-
-
-\begin{description}
-\item[1 ]  Iterator `constructor' functions that set
-   the value of elements in the iteratorCol structure
-   that define the columns or arrays. These set the fitsfile
-    pointer, column name, column number, datatype, and iotype,

-    to be set with one function call (one supplies the column
-   name, the other the column number). \label{ffiterset}

-\chapter{ World Coordinate System Routines }
-
-The FITS community has adopted a set of keyword conventions that define
-the transformations needed to convert between pixel locations in an
-image and the corresponding celestial coordinates on the sky, or more
-generally, that define world coordinates that are to be associated with
-any pixel location in an n-dimensional FITS array. CFITSIO is distributed
-with a a few self-contained World Coordinate System (WCS) routines,
-however, these routines DO NOT support all the latest WCS conventions,
-so it is STRONGLY RECOMMENDED that software developers use a more robust
-external WCS library.  Several recommended libraries are:
-
-
-\begin{verbatim}
-  WCSLIB -  supported by Mark Calabretta
-  WCSTools - supported by Doug Mink
-  AST library - developed by the U.K. Starlink project
-\end{verbatim}
-
-More information about the WCS keyword conventions and links to all of
-these WCS libraries can be found on the FITS Support Office web site at
-http://fits.gsfc.nasa.gov under the WCS link.
-
-The functions provided in these external WCS libraries will need
-access to the  WCS keywords contained in the FITS file headers.
-One convenient way to pass this information to the external library is
-to use the fits\_hdr2str routine in CFITSIO (defined below) to copy the
-header keywords into one long string, and then pass this string to an
-interface routine in the external library that will extract
-the necessary WCS information (e.g., the 'wcspih' routine in the WCSLIB
-library and the 'astFitsChan' and 'astPutCards' functions in the AST
-library).
-
-
-\begin{description}
-\item[1 ] Concatenate the header keywords in the CHDU into a single long
-    string of characters. Each 80-character fixed-length keyword
-    record is appended to the output character string, in order, with
-    no intervening separator or terminating characters. The last header
-    record is terminated with a NULL character.  This routine allocates
-    memory for the returned character array, so the calling program must
-    free the memory when finished.
-
-    There are 2 related routines: fits\_hdr2str simply concatenates all
-    the existing keywords in the header; fits\_convert\_hdr2str is similar,
-    except that if the CHDU is a tile compressed image (stored in a binary
-    table) then it will first convert that header back to that of a
-    normal FITS image before concatenating the keywords.
-
-    Selected keywords may be excluded from the returned character string.
-    If the second parameter (nocomments) is TRUE (nonzero) then any
-    COMMENT, HISTORY, or blank keywords in the header will not be copied
-    to the output string.
-
-    The 'exclist' parameter may be used to supply a list of keywords
-    that are to be excluded from the output character string. Wild card
-    characters (*, ?, and \#) may be used in the excluded keyword names.
-    If no additional keywords are to be excluded, then set nexc = 0 and
-   specify NULL for the the **exclist  parameter.  \label{hdr2str}
-\end{description}
-
-\begin{verbatim}
-  int fits_hdr2str
-      (fitsfile *fptr, int nocomments, char **exclist, int nexc,

-\begin{description}
-\item[2 ]  The following CFITSIO routine is specifically designed for use
-in conjunction with the WCSLIB library.  It is not expected that
-applications programmers will call this routine directly, but it
-is documented here for completeness.  This routine extracts arrays
-from a binary table that contain WCS information using the -TAB table
-lookup convention.  See the documentation provided with the WCSLIB
- library for more information.  \label{wcstab}

-\section{ Self-contained WCS Routines}
-
-The following routines DO NOT support the more recent WCS conventions
-that have been approved as part of the FITS standard.  Consequently,
-the following routines ARE NOW DEPRECATED.  It is STRONGLY RECOMMENDED
-that software developers not use these routines, and instead use an
-external WCS library, as described in the previous section.
-
-These routines are included mainly for backward compatibility with
-existing software.  They support the following standard map
-projections: -SIN, -TAN, -ARC, -NCP, -GLS, -MER, and -AIT (these are the
-legal values for the coordtype parameter).  These routines are based
-on similar functions in Classic AIPS.  All the angular quantities are
-given in units of degrees.
-
-
-\begin{description}
-\item[1 ] Get the values of the basic set of standard FITS celestial coordinate
-    system keywords from the header of a FITS image (i.e., the primary
-    array or an IMAGE extension).  These values may then be passed to
-    the fits\_pix\_to\_world and fits\_world\_to\_pix routines that
-    perform the coordinate transformations.  If any or all of the WCS
-    keywords are not present, then default values will be returned. If
-    the first coordinate axis is the declination-like coordinate, then
-    this routine will swap them so that the longitudinal-like coordinate
-    is returned as the first axis.
-
-    The first routine (ffgics) returns
-    the primary WCS, whereas the second routine returns the particular
-    version of the WCS specified by the 'version' parameter, which much
-    be a character ranging from 'A' to 'Z' (or a blank character, which is
-    equivalent to calling ffgics).
-
-    If the file uses the newer 'CDj\_i' WCS transformation matrix
-    keywords instead of old style 'CDELTn' and 'CROTA2' keywords, then
-    this routine will calculate and return the values of the equivalent
-    old-style keywords.  Note that the conversion from the new-style
-    keywords to the old-style values is sometimes only an
-    approximation, so if the approximation is larger than an internally
-    defined threshold level, then CFITSIO will still return the
-    approximate WCS keyword values, but will also return with status =
-    APPROX\_WCS\_KEY, to warn the calling program that approximations
-    have been made.  It is then up to the calling program to decide
-    whether the approximations are sufficiently accurate for the
-    particular application, or whether more precise WCS transformations
-   must be performed using new-style WCS keywords directly. \label{ffgics}

-\chapter{  Hierarchical Grouping Routines }
-
-These functions allow for the creation and manipulation of FITS HDU
-Groups, as defined in "A Hierarchical Grouping Convention for FITS" by
-Jennings, Pence, Folk and Schlesinger:
-
-http://fits.gsfc.nasa.gov/group.html
-
-A group is a
-collection of HDUs whose association is defined by a {\it grouping
-table}.  HDUs which are part of a group are referred to as {\it member
-HDUs} or simply as {\it members}. Grouping table member HDUs may
-themselves be grouping tables, thus allowing for the construction of
-open-ended hierarchies of HDUs.
-
-Grouping tables contain one row for each member HDU. The grouping table
-columns provide identification information that allows applications to
-reference or "point to" the member HDUs. Member HDUs are expected, but
-not required, to contain a set of GRPIDn/GRPLCn keywords in their
-headers for each grouping table that they are referenced by. In this
-sense, the GRPIDn/GRPLCn keywords "link" the member HDU back to its
-Grouping table. Note that a member HDU need not reside in the same FITS
-file as its grouping table, and that a given HDU may be referenced by
-up to 999 grouping tables simultaneously.
-
-Grouping tables are implemented as FITS binary tables with up to six
-pre-defined column TTYPEn values: 'MEMBER\_XTENSION', 'MEMBER\_NAME',
-'MEMBER\_VERSION', 'MEMBER\_POSITION', 'MEMBER\_URI\_TYPE' and 'MEMBER\_LOCATION'.
-The first three columns allow member HDUs to be identified by reference to
-their XTENSION, EXTNAME and EXTVER keyword values. The fourth column allows
-member HDUs to be identified by HDU position within their FITS file.
-The last two columns identify the FITS file in which the member HDU resides,
-if different from the grouping table FITS file.
-
-Additional user defined "auxiliary" columns may also be included with any
-grouping table. When a grouping table is copied or modified the presence of
-auxiliary columns is always taken into account by the grouping support
-functions; however, the grouping support functions cannot directly
-make use of this data.
-
-If a grouping table column is defined but the corresponding member HDU
-information is unavailable then a null value of the appropriate data type
-is inserted in the column field. Integer columns (MEMBER\_POSITION,
-MEMBER\_VERSION) are defined with a TNULLn value of zero (0). Character field
-columns (MEMBER\_XTENSION, MEMBER\_NAME, MEMBER\_URI\_TYPE, MEMBER\_LOCATION)
-utilize an ASCII null character to denote a null field value.
-
-The grouping support functions belong to two basic categories: those that
-work with grouping table HDUs (ffgt**) and those that work with member HDUs
-(ffgm**). Two functions, fits\_copy\_group() and fits\_remove\_group(), have the
-option to recursively copy/delete entire groups. Care should be taken when
-employing these functions in recursive mode as poorly defined groups could
-cause unpredictable results. The problem of a grouping table directly or
-indirectly referencing itself (thus creating an infinite loop) is protected
-against; in fact, neither function will attempt to copy or delete an HDU
-twice.

-   function only adds or removes grouping table columns, it does not add
-   or delete group members (i.e., table rows). If the grouping table already
-   has the desired structure then no operations are performed and function
-   simply returns with a (0) success status code. If the requested structure

-   all members of the group defined by the grouping table. Valid values are:
-   OPT\_RM\_GPT (delete only the grouping table) and OPT\_RM\_ALL (recursively
-   delete all HDUs that belong to the group). Any groups containing the
-   grouping table gfptr as a member are updated, and if rmopt == OPT\_RM\_GPT
-   all members have their GRPIDn and GRPLCn  keywords updated accordingly.
-   If rmopt == OPT\_RM\_ALL, then other groups that contain the deleted members

-   members of the group infptr. Valid values are: OPT\_GCP\_GPT (copy only
-   the grouping table) and OPT\_GCP\_ALL (recursively copy ALL the HDUs that
-   belong to the group defined by infptr). If the cpopt == OPT\_GCP\_GPT then
-   the members of infptr have their GRPIDn and GRPLCn keywords updated to
-   reflect the existence of the new grouping table outfptr, since they now
-   belong to the new group. If cpopt == OPT\_GCP\_ALL then the new
-   grouping table outfptr only contains pointers to the copied member HDUs
-   and not the original member HDUs of infptr. Note that, when
-   cpopt == OPT\_GCP\_ALL, all members of the group defined by infptr will be
-   copied to a single FITS file pointed to by outfptr regardless of their
-  file distribution in the original group.  \label{ffgtcp}

-\item[6 ] Merge the two groups defined by the grouping table HDUs infptr and outfptr
-    by combining their members into a single grouping table. All member HDUs
-    (rows) are copied from infptr to outfptr. If mgopt == OPT\_MRG\_COPY then
-    infptr continues to exist unaltered after the merge. If the mgopt ==

-\item[7 ]"Compact" the group defined by grouping table pointed to by gfptr. The
-   compaction is achieved by merging (via fits\_merge\_groups()) all direct
-   member HDUs of gfptr that are themselves grouping tables. The cmopt
-   parameter defines whether the merged grouping table HDUs remain after
-   merging (cmopt == OPT\_CMT\_MBR) or if they are deleted after merging
-   (cmopt == OPT\_CMT\_MBR\_DEL). If the grouping table contains no direct
-   member HDUs that are themselves grouping tables then this function
-   does nothing. Note that this function is not recursive, i.e., only the
-  direct member HDUs of gfptr are considered for merging. \label{ffgtcm}

-\item[8 ]Verify the integrity of the grouping table pointed to by gfptr to make
-   sure that all group members are accessible and that all links to other
-   grouping tables are valid. The firstfailed parameter returns the member
-   ID (row number) of the first member HDU to fail verification (if positive

-\item[9 ] Open a grouping table that contains the member HDU pointed to by mfptr.
-    The grouping table to open is defined by the grpid parameter, which
-    contains the keyword index value of the GRPIDn/GRPLCn keyword(s) that
-    link the member HDU mfptr to the grouping table. If the grouping table
-    resides in a file other than the member HDUs file then an attempt is
-    first made to open the file readwrite, and failing that readonly. A
-    pointer to the opened grouping table HDU is returned in gfptr.
-
-    Note that it is possible, although unlikely and undesirable, for the
-    GRPIDn/GRPLCn keywords in a member HDU header to be non-continuous, e.g.,
-    GRPID1, GRPID2, GRPID5, GRPID6. In such cases, the grpid index value
-    specified in the function call shall identify the (grpid)th GRPID value.
-    In the above example, if grpid == 3, then the group specified by GRPID5
-   would be opened. \label{ffgtop}

-   (the HDU position number, Primary array == 1) if both the grouping table
-   and the member HDU reside in the same FITS file. The new member HDU shall
-   have the appropriate GRPIDn and GRPLCn keywords created in its header.

-    the opened member HDU is returned as mfptr. Note that if the member HDU

-\section{FITS File Access Routines}
-
-
-\begin{description}
-\item[1 ] Open an existing FITS file residing in core computer memory.  This
-routine is analogous to fits\_open\_file.   The 'filename'  is
-currently ignored by this routine and may be any arbitrary string. In
-general, the application must have preallocated an initial block of
-memory to hold the FITS file prior to calling this routine:  'memptr'
-points to the starting address and 'memsize' gives the initial size of
-the block of memory.  'mem\_realloc' is a pointer to an optional
-function that CFITSIO can call to allocate additional memory, if needed
-(only if mode = READWRITE), and is modeled after the standard C
-'realloc' function;  a null pointer may be given if the initial
-allocation of memory is all that will be required (e.g., if the file is
-opened with mode = READONLY).  The 'deltasize' parameter may be used to
-suggest a minimum amount of additional memory that should be allocated
-during each call to the memory reallocation function.  By default,
-CFITSIO will reallocate enough additional space to hold the entire
-currently defined FITS file (as given by the NAXISn keywords) or 1 FITS
-block (= 2880 bytes), which ever is larger.  Values of deltasize less
-than 2880 will be ignored.  Since the memory reallocation operation can
-be computationally expensive, allocating a larger initial block of
-memory, and/or specifying a larger deltasize value may help to reduce
-the number of reallocation calls and make the application program run
-faster.  Note that values of the memptr and memsize pointers will be updated
-by CFITSIO if the location or size of the FITS file in memory
-should change as a result of allocating more memory. \label{ffomem}

-\item[2 ] Create a new FITS file residing in core computer memory.  This
-routine is analogous to fits\_create\_file.    In general, the
-application must have preallocated an initial block of memory to hold
-the FITS file prior to calling this routine:  'memptr' points to the

-\item[3 ] Reopen a FITS file that was previously opened with

-    pointer may then be treated as a separate file, and one may
-    simultaneously read or write to 2 (or more)  different extensions in
-    the same file.   The fits\_open\_file routine (above) automatically
-    detects cases where a previously opened file is being opened again,
-    and then internally call fits\_reopen\_file, so programs should rarely
-    need to explicitly call this routine.

-\item[5 ] Parse the input filename or URL into its component parts, namely:
-\begin{itemize}
-\item
-the file type (file://, ftp://, http://, etc),
-\item
-the base input file name,
-\item
-the name of the output file that the input file is to be copied to prior

-and the
-image pixel filtering specifier.
-\end{itemize}
-A null pointer (0) may be be specified for any of the output string arguments
-that are not needed.  Null strings will be returned for any components that are not
-present in the input file name.  The calling routine must allocate sufficient
-memory to hold the returned character strings.  Allocating the string lengths
-equal to FLEN\_FILENAME is guaranteed to be safe.
-These routines are mainly for internal use

-
-\begin{description}
-\item[6 ] Parse the input filename and return the HDU number that would be
-moved to if the file were opened with fits\_open\_file.  The returned
-HDU number begins with 1 for the primary array, so for example, if the
-input filename = `myfile.fits[2]' then hdunum = 3 will be returned.
-CFITSIO does not open the file to check if the extension actually
-exists if an extension number is specified. If an extension name is
-included in the file name specification (e.g.  `myfile.fits[EVENTS]'
-then this routine will have to open the FITS file and look for the
-position of the named extension, then close file again.  This is not
-possible if the file is being read from the stdin stream, and an error
-will be returned in this case.  If the filename does not specify an
-explicit extension (e.g. 'myfile.fits') then hdunum = -99 will be
-returned, which is functionally equivalent to hdunum = 1. This routine
-is mainly used for backward compatibility in the ftools software
-package and is not recommended for general use.  It is generally better
-and more efficient to first open the FITS file with fits\_open\_file,
-then use fits\_get\_hdu\_num to determine which HDU in the file has
-been opened, rather than calling fits\_parse\_input\_url followed by a
-call to fits\_open\_file.

-name includes the file type if specified, (e.g.  'ftp://' or 'http://')
-and the full path name, to the extent that it is specified in the input
-filename.  It does not include the HDU name or number, or any filtering
-specifications. The calling routine must allocate sufficient

-
-\begin{verbatim}
-   2:  the file does not exist, but a compressed version does exist
-   1:  the disk file does exist
-   0:  neither the file nor a compressed version of the file exist

-\item[9 ]Flush any internal buffers of data to the output FITS file. These
-   routines rarely need to be called, but can be useful in cases where
-   other processes need to access the same FITS file in real time,
-   either on disk or in memory.  These routines also help to ensure
-   that if the application program subsequently aborts then the FITS
-   file will have been closed properly.  The first routine,
-   fits\_flush\_file is more rigorous and completely closes, then
-   reopens, the current HDU, before flushing the internal buffers, thus
-   ensuring that the output FITS file is identical to what would be
-   produced if the FITS was closed at that point (i.e., with a call to
-   fits\_close\_file).  The second routine, fits\_flush\_buffer simply
-   flushes the internal CFITSIO buffers of data to the output FITS
-   file, without updating and closing the current HDU.  This is much
-   faster, but there may be circumstances where the flushed file does
-   not completely reflect the final state of the file as it will exist
-   when the file is actually closed.
-
-   A typical use of these routines would be to flush the state of a
-   FITS table to disk after each row of the table is written.  It is
-   recommend that fits\_flush\_file be called after the first row is
-   written, then fits\_flush\_buffer may be called after each
-   subsequent row is written.  Note that this latter routine will not
-   automatically update the NAXIS2 keyword which records the number of
-   rows of data in the table, so this keyword must be explicitly
-   updated by the application program after each row is written.

-\item[2 ] Create (append) a new empty HDU at the end of the FITS file.
-    This is now  the CHDU but it is completely empty and has

-\begin{description}
-\item[3 ] Insert a new IMAGE extension immediately following the CHDU, or
-    insert a new Primary Array at the beginning of the file.  Any
-    following extensions in the file will be shifted down to make room
-    for the new extension.  If the CHDU is the last HDU in the file
-    then the new image extension will simply be appended to the end of
-    the file.   One can force a new primary array to be inserted at the
-    beginning of the FITS file by setting status = PREPEND\_PRIMARY prior
-    to calling the routine.  In this case the old primary array will be
-    converted to an IMAGE extension. The new extension (or primary
-    array) will become the CHDU.  Refer to Chapter 9 for a list of
-   pre-defined bitpix values.  \label{ffiimg}

-\end{verbatim}
-
-\begin{description}
-\item[4 ] Insert a new ASCII or binary table extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for the
-    new extension.  If there are no other following extensions then the
-    new table extension will simply be appended to the end of the
-    file.   If the FITS file is currently empty then this routine will
-    create a dummy primary array before appending the table to it. The
-    new extension will become the CHDU.  The tunit and extname
-    parameters are optional and a null pointer may be given if they are
-    not defined.  When inserting an ASCII table with
-    fits\_insert\_atbl, a null pointer  may given for the *tbcol
-    parameter in which case each column of the table will be separated
-    by a single space character. Similarly, if the input value of
-    rowlen is  0, then CFITSIO will calculate the default rowlength
-    based on the tbcol and ttype values.  Under normal circumstances,
-    the nrows
-    paramenter should have a value of 0; CFITSIO will automatically update
-    the number of rows as data is written to the table.  When inserting a binary table
-    with fits\_insert\_btbl, if there are following extensions in the
-    file and if the table contains variable length array columns then
-    pcount must specify the expected final size of the data heap,
-   otherwise pcount must = 0. \label{ffitab} \label{ffibin}

-\end{verbatim}
-
-\begin{description}
-\item[5 ] Modify the size, dimensions, and/or data type of the current
-    primary array or image extension. If the new image, as specified
-    by the input arguments, is larger than the current existing image
-    in the FITS file then zero fill data will be inserted at the end
-    of the current image and any following extensions will be moved
-    further back in the file.  Similarly, if the new image is
-    smaller than the current image then any following extensions
-    will be shifted up towards the beginning of the FITS file
-    and the image data will be truncated to the new size.
-    This routine rewrites the BITPIX, NAXIS, and NAXISn keywords
-   with the appropriate values for the new image. \label{ffrsim}

-\item[6 ] Copy the data (and not the header) from the CHDU associated with infptr
-    to the CHDU associated with outfptr. This will overwrite any data
-    previously in the output CHDU.  This low level routine is used by
-    fits\_copy\_hdu, but it may also be useful in certain application programs
-    that want to copy the data from one FITS file to another but also
-    want to modify the header keywords. The required FITS header keywords
-    which define the structure of the HDU must be written to the
-   output CHDU before calling this routine. \label{ffcpdt}

-\item[7 ] Read or write a specified number of bytes starting at the specified byte
-    offset from the start of the extension data unit.  These low

-\item[8 ] This routine forces CFITSIO to rescan the current header keywords that
-    define the structure of the HDU (such as the NAXIS and BITPIX
-    keywords) so that it reinitializes the internal buffers that
-    describe the HDU structure.  This routine is useful for
-    reinitializing the structure of an HDU if any of the required
-    keywords (e.g., NAXISn) have been modified.  In practice it should
-    rarely be necessary to call this routine because CFITSIO

-\section{Specialized Header Keyword Routines}
-
-
-\subsection{Header Information Routines}
-
-
-\begin{description}
-\item[1 ] Reserve space in the CHU for MOREKEYS more header keywords.
-    This routine may be called to allocate space for additional keywords
-    at the time the header is created (prior to writing any data).
-    CFITSIO can dynamically add more space to the header when needed,
-    however it is more efficient to preallocate the required space
-   if the size is known in advance. \label{ffhdef}
-\end{description}
-
-\begin{verbatim}
-  int fits_set_hdrsize / ffhdef
-      (fitsfile *fptr, int morekeys, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Return the number of keywords in the header (not counting the END
-    keyword) and the current position
-    in the header.  The position is the number of the keyword record that
-    will be read next (or one greater than the position of the last keyword
-    that was read). A value of 1 is returned if the pointer is
-   positioned at the beginning of the header. \label{ffghps}
-\end{description}
-
-\begin{verbatim}
-  int fits_get_hdrpos / ffghps
-      (fitsfile *fptr, > int *keysexist, int *keynum, int *status)
-\end{verbatim}
-
-
-\subsection{Read and Write the Required Keywords}
-
-
-\begin{description}
-\item[1 ] Write the required extension header keywords into the CHU.
-  These routines are not required, and instead the appropriate
-  header may be constructed by writing each individual keyword in the
-  proper sequence.
-
-  The simpler fits\_write\_imghdr routine is equivalent to calling
-  fits\_write\_grphdr with the default values of simple = TRUE, pcount
-  = 0, gcount = 1, and extend = TRUE.  The PCOUNT, GCOUNT and EXTEND
-  keywords are not required in the primary header and are only written
-  if pcount is not equal to zero, gcount is not equal to zero or one,
-  and if extend is TRUE, respectively.  When writing to an IMAGE
-  extension, the SIMPLE and EXTEND parameters are ignored.  It is
-  recommended that fits\_create\_image or fits\_create\_tbl be used
-  instead of these routines to write the
-  required header keywords. The general fits\_write\_exthdr routine
-  may be used to write the header of any conforming FITS
- extension.  \label{ffphpr} \label{ffphps}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_imghdr / ffphps
-      (fitsfile *fptr, int bitpix, int naxis, long *naxes, > int *status)
-
-  int fits_write_imghdrll / ffphpsll

-       LONGLONG pcount, LONGLONG gcount, > int *status)
-
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Write the ASCII table header keywords into the CHU.  The optional
-    TUNITn and EXTNAME keywords are written only if the input pointers
-    are not null.  A null pointer may given for the
-    *tbcol parameter in which case a single space will be inserted
-    between each column of the table.  Similarly, if rowlen is
-    given = 0, then CFITSIO will calculate the default rowlength based on
-   the tbcol and ttype values. \label{ffphtb}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_atblhdr / ffphtb
-      (fitsfile *fptr, LONGLONG rowlen, LONGLONG nrows, int tfields, char **ttype,
-       long *tbcol, char **tform, char **tunit, char *extname, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Write the binary table header keywords into the CHU.   The optional
-   TUNITn and EXTNAME keywords are written only if the input pointers
-   are not null.  The pcount parameter, which specifies the
-   size of the variable length array heap, should initially = 0;
-   CFITSIO will automatically update the PCOUNT keyword value if any
-   variable length array data is written to the heap.  The TFORM keyword
-   value for variable length vector columns should have the form 'Pt(len)'
-   or '1Pt(len)' where `t' is the data type code letter (A,I,J,E,D, etc.)
-   and  `len' is an integer specifying the maximum length of the vectors
-   in that column (len must be greater than or equal to the longest
-   vector in the column).  If `len' is not specified when the table is
-   created (e.g., the input TFORMn value is just '1Pt') then CFITSIO will
-   scan the column when the table is first closed and will append the
-   maximum length to the TFORM keyword value.  Note that if the table
-   is subsequently modified to increase the maximum length of the vectors
-   then the modifying program is responsible for also updating the TFORM
-  keyword value.  \label{ffphbn}
-\end{description}

-\end{verbatim}
-
-\begin{description}
-\item[4 ] Read the required keywords from the CHDU (image or table).  When
-    reading from an IMAGE extension the SIMPLE and EXTEND parameters are
-    ignored.  A null pointer may be supplied for any of the returned
-   parameters that are not needed. \label{ffghpr} \label{ffghtb} \label{ffghbn}

-\subsection{Write Keyword Routines}
-
-These routines simply append a new keyword to the header and do not
-check to see if a keyword with the same name already exists.  In
-general it is preferable to use the fits\_update\_key routine to ensure
-that the same keyword is not written more than once to the header.  See
-Appendix B for the definition of the parameters used in these
-routines.
-
-
-
-\begin{description}
-\item[1 ]  Write (append) a new keyword of the appropriate data type into the CHU.
-     A null pointer may be entered for the comment parameter, which
-     will cause the comment field of the keyword to be left blank.  The
-     flt, dbl, cmp, and dblcmp versions of this routine have the added
-     feature that if the 'decimals' parameter is negative, then the 'G'
-     display format rather then the 'E' format will be used when
-     constructing the keyword value, taking the absolute value of
-     'decimals' for the precision.  This will suppress trailing zeros,
-     and will use a fixed format rather than an exponential format,
-    depending on the magnitude of the value. \label{ffpkyx}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_key_str / ffpkys
-      (fitsfile *fptr, char *keyname, char *value, char *comment,

-      (fitsfile *fptr, char *keyname, DTYPE *numval, int decimals,
-      char *comment, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Write (append) a string valued keyword into the CHU which may be longer
-    than 68 characters in length.  This uses the Long String Keyword
-    convention that is described in the`Local FITS Conventions' section
-    in Chapter 4.  Since this uses a non-standard FITS convention to
-    encode the long keyword string, programs which use this routine
-    should also call the fits\_write\_key\_longwarn routine to add some
-    COMMENT keywords to warn users of the FITS file that this
-    convention is being used.  The fits\_write\_key\_longwarn routine
-    also writes a keyword called LONGSTRN to record the version of the
-    longstring convention that has been used, in case a new convention
-    is adopted at some point in the future.   If the LONGSTRN keyword
-    is already present in the header, then fits\_write\_key\_longwarn
-    will
-   simply return without doing anything. \label{ffpkls} \label{ffplsw}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_key_longstr / ffpkls
-      (fitsfile *fptr, char *keyname, char *longstr, char *comment,
-       > int *status)
-
-  int fits_write_key_longwarn / ffplsw
-      (fitsfile *fptr, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Write (append) a numbered sequence of keywords into the CHU.  The
-    starting index number (nstart) must be greater than 0. One may
-    append the same comment to every keyword (and eliminate the need
-    to have an array of identical comment strings, one for each keyword) by
-    including the ampersand character as the last non-blank character in the
-    (first) COMMENTS string parameter.  This same string
-    will then be used for the comment field in all the keywords.
-    One may also enter a null pointer for the comment parameter to
-   leave the comment field of the keyword blank. \label{ffpknx}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_keys_str / ffpkns
-      (fitsfile *fptr, char *keyroot, int nstart, int nkeys,
-       char **value, char **comment, > int *status)
-
-  int fits_write_keys_[log, lng] / ffpkn[lj]
-      (fitsfile *fptr, char *keyroot, int nstart, int nkeys,
-       DTYPE *numval, char **comment, int *status)
-
-  int fits_write_keys_[flt, dbl, fixflg, fixdbl] / ffpkne[edfg]
-      (fitsfile *fptr, char *keyroot, int nstart, int nkey,
-       DTYPE *numval, int decimals, char **comment, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]Copy an indexed keyword from one HDU to another, modifying
-    the index number of the keyword name in the process.  For example,
-    this routine could read the TLMIN3 keyword from the input HDU
-    (by giving keyroot = `TLMIN' and innum = 3) and write it to the
-    output HDU with the keyword name TLMIN4 (by setting outnum = 4).
-    If the input keyword does not exist, then this routine simply
-   returns without indicating an error. \label{ffcpky}
-\end{description}
-
-\begin{verbatim}
-  int fits_copy_key / ffcpky
-      (fitsfile *infptr, fitsfile *outfptr, int innum, int outnum,
-       char *keyroot, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[5 ]Write (append) a `triple precision' keyword into the CHU in F28.16 format.
-    The floating point keyword value is constructed by concatenating the
-    input integer value with the input double precision fraction value
-    (which must have a value between 0.0 and 1.0). The ffgkyt routine should
-    be used to read this keyword value, because the other keyword reading
-   routines will not preserve the full precision of the value. \label{ffpkyt}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_key_triple / ffpkyt
-      (fitsfile *fptr, char *keyname, long intval, double frac,
-       char *comment, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ]Write keywords to the CHDU that are defined in an ASCII template file.
-   The format of the template file is described under the fits\_parse\_template
-  routine. \label{ffpktp}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_key_template / ffpktp
-      (fitsfile *fptr, const char *filename, > int *status)
-\end{verbatim}
-
-\subsection{Insert Keyword Routines}
-
-These insert routines are somewhat less efficient than the `update' or
-`write' keyword routines  because the following keywords in the header
-must be shifted down to make room for the inserted keyword.  See
-Appendix B for the definition of the parameters used in these
-routines.
-
-
-\begin{description}
-\item[1 ] Insert a new keyword record into the CHU at the specified position
-    (i.e., immediately preceding the (keynum)th keyword in the header.)
-  \label{ffirec}
-\end{description}
-
-\begin{verbatim}
-  int fits_insert_record / ffirec
-      (fitsfile *fptr, int keynum, char *card, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Insert a new keyword into the CHU.  The new keyword is inserted
-    immediately following the last keyword that has been read from the
-    header.  The `longstr' version has the same functionality as the
-    `str' version except that it also supports the local long string
-    keyword convention for strings longer than 68 characters.  A null
-    pointer may be entered for the comment parameter which will cause
-    the comment field to be left blank.  The flt, dbl, cmp, and dblcmp
-    versions of this routine have the added
-     feature that if the 'decimals' parameter is negative, then the 'G'
-     display format rather then the 'E' format will be used when
-     constructing the keyword value, taking the absolute value of
-     'decimals' for the precision.  This will suppress trailing zeros,
-     and will use a fixed format rather than an exponential format,
-    depending on the magnitude of the value. \label{ffikyx}

-\subsection{Read Keyword Routines}
-
-Wild card characters may be used when specifying the name of the
-keyword to be read.
-
-
-\begin{description}
-\item[1 ] Read a keyword value (with the appropriate data type) and comment from
-    the CHU.  If a NULL comment pointer is given on input, then the comment
-    string will not be returned.  If the value of the keyword is not defined
-    (i.e., the value field is blank) then an error status = VALUE\_UNDEFINED
-    will be returned and the input value will not be changed (except that
-    ffgkys will reset the value to a null string).

-\begin{verbatim}
-  int fits_read_key_str / ffgkys
-      (fitsfile *fptr, char *keyname, > char *value, char *comment,

-
-  NOTE: after calling the following routine, programs must explicitly free
-        the memory allocated for 'longstr' after it is no longer needed or

-\section{Define Data Scaling and Undefined Pixel Parameters}
-
-These routines set or modify the internal parameters used by CFITSIO
-to either scale the data or to represent undefined pixels.  Generally
-CFITSIO will scale the data according to the values of the BSCALE and
-BZERO (or TSCALn and TZEROn) keywords, however these routines may be
-used to override the keyword values.  This may be useful when one wants
-to read or write the raw unscaled values in the FITS file.  Similarly,
-CFITSIO generally uses the value of the BLANK or TNULLn keyword to
-signify an undefined pixel, but these routines may be used to override
-this value.  These routines do not create or modify the corresponding
-header keyword values.  See Appendix B for the definition of the
-parameters used in these routines.

-\section{Specialized FITS Primary Array or IMAGE Extension I/O Routines}
-
-These routines read or write data values in the primary data array
-(i.e., the first HDU in the FITS file) or an IMAGE extension.
-Automatic data type conversion is performed for if the data type of the
-FITS array (as defined by the BITPIX keyword) differs from the data
-type of the array in the calling routine.  The data values are
-automatically scaled by the BSCALE and BZERO header values as they are
-being written or read from the FITS array.  Unlike the basic routines
-described in the previous chapter, most of these routines specifically
-support the FITS random groups format.  See Appendix B for the
-definition of the parameters used in these routines.
-
-The more primitive reading and writing routines (i. e., ffppr\_,
-ffppn\_, ffppn, ffgpv\_, or ffgpf\_) simply treat the primary array as
-a long 1-dimensional array of pixels, ignoring the intrinsic
-dimensionality of the array.  When dealing with a 2D image, for
-example, the application program must calculate the pixel offset in the
-1-D array that corresponds to any particular X, Y coordinate in the
-image.  C programmers should note that the ordering of arrays in FITS
-files, and hence in all the CFITSIO calls, is more similar to the
-dimensionality of arrays in Fortran rather than C.  For instance if a
-FITS image has NAXIS1 = 100 and NAXIS2 = 50, then a 2-D array just
-large enough to hold the image should be declared as array[50][100] and
-not as array[100][50].
-
-For convenience, higher-level routines are also provided to specifically
-deal with 2D images (ffp2d\_ and ffg2d\_) and 3D data cubes (ffp3d\_
-and ffg3d\_).  The dimensionality of the FITS image is passed by the
-naxis1, naxis2, and naxis3 parameters and the declared dimensions of
-the program array are passed in the dim1 and dim2 parameters.  Note
-that the dimensions of the program array may be larger than the
-dimensions of the FITS array.  For example if a FITS image with NAXIS1
-= NAXIS2 = 400 is read into a program array which is dimensioned as 512
-x 512 pixels, then the image will just fill the lower left corner of
-the array with pixels in the range 1 - 400 in the X an Y directions.
-This has the effect of taking a contiguous set of pixel value in the
-FITS array and writing them to a non-contiguous array in program memory
-(i.e., there are now some blank pixels around the edge of the image in
-the program array).
-
-The most general set of routines (ffpss\_, ffgsv\_, and ffgsf\_) may be
-used to transfer a rectangular subset of the pixels in a FITS
-N-dimensional image to or from an array which has been declared in the
-calling program.  The fpixel and lpixel parameters are integer arrays
-which specify the starting and ending pixel coordinate in each dimension
-(starting with 1, not 0) of the FITS image that is to be read or
-written.  It is important to note that these are the starting and
-ending pixels in the FITS image, not in the declared array in the
-program. The array parameter in these routines is treated simply as a
-large one-dimensional array of the appropriate data type containing the
-pixel values; The pixel values in the FITS array are read/written
-from/to this program array in strict sequence without any gaps;  it is
-up to the calling routine to correctly interpret the dimensionality of
-this array.  The two FITS reading routines (ffgsv\_ and ffgsf\_ ) also
-have an `inc' parameter which defines the data sampling interval in
-each dimension of the FITS array.  For example, if inc[0]=2 and
-inc[1]=3 when reading a 2-dimensional FITS image, then only every other
-pixel in the first dimension and every 3rd pixel in the second
-dimension will be returned to the 'array' parameter.
-
-Two types of routines are provided to read the data array which differ in
-the way undefined pixels are handled.  The first type of routines (e.g.,
-ffgpv\_) simply return an array of data elements in which undefined
-pixels are set equal to a value specified by the user in the `nulval'
-parameter.  An additional feature of these routines is that if the user
-sets nulval = 0, then no checks for undefined pixels will be performed,
-thus reducing the amount of CPU processing.  The second type of routines
-(e.g., ffgpf\_) returns the data element array and, in addition, a char
-array that indicates whether the value of the corresponding data pixel
-is undefined (= 1) or defined (= 0).  The latter type of routines may
-be more convenient to use in some circumstances, however, it requires
-an additional array of logical values which can be unwieldy when working
-with large data arrays.

-\item[2 ] Return optimal number of rows to read or write at one time for

-\item[3 ] Define the zero indexed byte offset of the 'heap' measured from
-    the start of the binary table data.  By default the heap is assumed
-    to start immediately following the regular table data, i.e., at
-    location NAXIS1 x NAXIS2.  This routine is only relevant for
-    binary tables which contain variable length array columns (with
-    TFORMn = 'Pt').  This routine also automatically writes
-    the value of theap to a keyword in the extension header.  This
-    routine must be called after the required keywords have been

-\item[5 ] Re-pack the vectors in the binary table variable array heap to recover
-    any unused space.  Normally, when a vector in a variable length
-    array column is rewritten the previously written array remains in
-    the heap as wasted unused space.  This routine will repack the
-    arrays that are still in use, thus eliminating any bytes in the
-    heap that are no longer in use.  Note that if several vectors point
-    to the same bytes in the heap, then this routine will make
-    duplicate copies of the bytes for each vector, which will actually
-   expand the size of the heap. \label{ffcmph}

-\subsection{Low-Level Table Access Routines}
-
-The following 2 routines provide low-level access to the data in ASCII
-or binary tables and are mainly useful as an efficient way to copy all
-or part of a table from one location to another.  These routines simply
-read or write the specified number of consecutive bytes in an ASCII or
-binary table, without regard for column boundaries or the row length in
-the table.  These routines do not perform any machine dependent data
-conversion or byte swapping.  See Appendix B for the definition of the
-parameters used in these routines.
-
-
-\begin{description}
-\item[1 ] Read or write a consecutive array of bytes from an ASCII or binary
-   table \label{ffgtbb}  \label{ffptbb}
-\end{description}
-
-\begin{verbatim}
-  int fits_read_tblbytes / ffgtbb
-      (fitsfile *fptr, LONGLONG firstrow, LONGLONG firstchar, LONGLONG nchars,

-
-  int fits_write_tblbytes / ffptbb
-      (fitsfile *fptr, LONGLONG firstrow, LONGLONG firstchar, LONGLONG nchars,
-       unsigned char *values, > int *status)
-\end{verbatim}
-
-
-\subsection{Write Column Data Routines}
-
-
-\begin{description}
-\item[1 ] Write elements into an ASCII or binary table column (in the CDU).
-    The data type of the array is implied by the suffix of the
-   routine name. \label{ffpcls}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_col_str / ffpcls
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, LONGLONG firstelem,

-           LONGLONG firstelem, LONGLONG nelements, DTYPE *array, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Write elements into an ASCII or binary table column
-    substituting the appropriate FITS null value for any elements that
-    are equal to the nulval parameter.    \label{ffpcnx}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_colnull_[log, byt, sht, usht, int, uint, lng, ulng, lnglng, flt, dbl] /
-      ffpcn[l,b,i,ui,k,uk,j,uj,jj,e,d]
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, LONGLONG firstelem,
-       LONGLONG nelements, DTYPE *array, DTYPE nulval, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Write string elements into a binary table column (in the CDU)
-    substituting the FITS null value for any elements that
-   are equal to the nulstr string.  \label{ffpcns}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_colnull_str / ffpcns
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, LONGLONG firstelem,
-       LONGLONG nelements, char **array, char *nulstr, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ] Write bit values into a binary byte ('B') or bit ('X') table column (in
-    the CDU).  Larray is an array of characters corresponding to the
-    sequence of bits to be written.  If an element of larray is true
-    (not equal to zero) then the corresponding bit in the FITS table is
-    set to 1, otherwise the bit is set to 0.  The 'X' column in a FITS
-    table is always padded out to a multiple of 8 bits where the bit
-    array starts with the most significant bit of the byte and works
-    down towards the 1's bit.  For example, a '4X' array, with the
-    first bit = 1 and the remaining 3 bits = 0 is equivalent to the 8-bit
-    unsigned byte decimal value of 128  ('1000 0000B').  In the case of
-    'X' columns, CFITSIO can write to all 8 bits of each byte whether
-    they are formally valid or not.  Thus if the column is defined as
-    '4X', and one calls ffpclx with firstbit=1 and nbits=8, then all
-    8 bits will be written into the first byte (as opposed to writing
-    the first 4 bits into the first row and then the next 4 bits into
-    the next row), even though the last 4 bits of each byte are formally
-    not defined and should all be set = 0.  It should also be noted that
-    it is more efficient to write 'X' columns an entire byte at a time,
-    instead of bit by bit.  Any of the CFITSIO routines that write to
-    columns (e.g. fits\_write\_col\_byt) may be used for this purpose.
-    These routines will interpret 'X' columns as though they were 'B'
-    columns (e.g.,  '1X' through '8X' is equivalent
-   to '1B', and '9X' through '16X' is equivalent to '2B').  \label{ffpclx}
-\end{description}
-
-\begin{verbatim}
-  int fits_write_col_bit / ffpclx
-      (fitsfile *fptr, int colnum, LONGLONG firstrow, long firstbit,
-       long nbits, char *larray, > int *status)
-\end{verbatim}
-
-\begin{description}
-\item[5 ] Write the descriptor for a variable length column in a binary table.
-    This routine can be used in conjunction with ffgdes to enable
-    2 or more arrays to point to the same storage location to save
-   storage space if the arrays are identical. \label{ffpdes}
-\end{description}
-
-\begin{verbatim}
-    int fits_write_descript / ffpdes
-        (fitsfile *fptr, int colnum, LONGLONG rownum, LONGLONG repeat,
-         LONGLONG offset, > int *status)
-\end{verbatim}
-
-\subsection{Read Column Data Routines}
-
-Two types of routines are provided to get the column data which differ
-in the way undefined pixels are handled.  The first set of routines
-(ffgcv) simply return an array of data elements in which undefined
-pixels are set equal to a value specified by the user in the 'nullval'
-parameter.  If nullval = 0, then no checks for undefined pixels will be
-performed, thus increasing the speed of the program.  The second set of
-routines (ffgcf) returns the data element array and in addition a
-logical array of flags which defines whether the corresponding data
-pixel is undefined.  See Appendix B for the definition of the
-parameters used in these routines.
-
-    Any column, regardless of it's intrinsic data type, may be read as a
-    string.  It should be noted however that reading a numeric column as
-    a string is 10 - 100 times slower than reading the same column as a number
-    due to the large overhead in constructing the formatted strings.
-    The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    data type of the column.  The length of the returned strings (not
-    including the null terminating character) can be determined with
-    the fits\_get\_col\_display\_width routine.  The following TDISPn
-    display formats are currently supported:
-
-\begin{verbatim}
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
-\end{verbatim}
-    where w is the width in characters of the displayed values, m is
-    the minimum number of digits displayed, and d is the number of
-    digits to the right of the decimal.  The .m field is optional.
-
-
-\begin{description}
-\item[1 ] Read elements from an ASCII or binary table column (in the CDU).  These

-\item[5 ] Read bit values from a byte ('B') or bit (`X`) table column (in the
-    CDU).  Larray is an array of logical values corresponding to the
-    sequence of bits to be read.  If larray is true then the
-    corresponding bit was set to 1, otherwise the bit was set to 0.
-    The 'X' column in a FITS table is always padded out to a multiple

-    equivalent to the 8-bit unsigned byte value of 128.
-    Note that in the case of 'X' columns, CFITSIO can read  all 8 bits
-    of each byte whether they are formally valid or not.  Thus if the

-\chapter{ Extended File Name Syntax }
-
-
-\section{Overview}
-
-CFITSIO supports an extended syntax when specifying the name of the
-data file to be opened or created  that includes the following
-features:
-
-\begin{itemize}
-\item
-CFITSIO can read IRAF format images which have header file names that
-end with the '.imh' extension, as well as reading and writing FITS
-files,   This feature is implemented in CFITSIO by first converting the
-IRAF image into a temporary FITS format file in memory, then opening
-the FITS file.  Any of the usual CFITSIO routines then may be used to
-read the image header or data.  Similarly, raw binary data arrays can
-be read by converting them on the fly into virtual FITS images.
-
-\item
-FITS files on the Internet can be read (and sometimes written) using the FTP,
-HTTP, or ROOT protocols.
-
-\item
-FITS files can be piped between tasks on the stdin and stdout streams.
-
-\item
-FITS files can be read and written in shared memory.  This can
-potentially achieve better data I/O performance compared to reading and
-writing the same FITS files on magnetic disk.
-
-\item
-Compressed FITS files in gzip or Unix COMPRESS format can be directly read.
-
-\item
-Output FITS files can be written directly in compressed gzip format,
-thus saving disk space.
-
-\item
-FITS table columns can be created, modified, or deleted 'on-the-fly' as
-the table is opened by CFITSIO.  This creates a virtual FITS file containing
-the modifications that is then opened by the application program.
-
-\item
-Table rows may be selected, or filtered out, on the fly when the table
-is opened by CFITSIO, based on an user-specified expression.
-Only rows for which the expression evaluates to 'TRUE' are retained
-in the copy of the table that is opened by the application program.
-
-\item
-Histogram images may be created on the fly by binning the values in
-table columns, resulting in a virtual N-dimensional FITS image.  The
-application program then only sees the FITS image (in the primary
-array) instead of the original FITS table.
-\end{itemize}
-
-The latter 3 table filtering features in particular add very powerful
-data processing capabilities directly into CFITSIO, and hence into
-every task that uses CFITSIO to read or write FITS files.  For example,
-these features transform a very simple program that just copies an
-input FITS file to a new output file (like the `fitscopy' program that
-is distributed with CFITSIO) into a multipurpose FITS file processing
-tool.  By appending fairly simple qualifiers onto the name of the input
-FITS file, the user can perform quite complex table editing operations
-(e.g., create new columns, or filter out rows in a table) or create
-FITS images by binning or histogramming the values in table columns.
-In addition, these functions have been coded using new state-of-the art
-algorithms that are, in some cases, 10 - 100 times faster than previous
-widely used implementations.
-
-Before describing the complete syntax for the extended FITS file names
-in the next section, here are a few examples of FITS file names that
-give a quick overview of the allowed syntax:
-
-\begin{itemize}
-\item
-{\tt myfile.fits}: the simplest case of a FITS file on disk in the current
-directory.
-
-\item
-{\tt myfile.imh}: opens an IRAF format image file and converts it on the
-fly into a temporary FITS format image in memory which can then be read with
-any other CFITSIO routine.
-
-\item
-{\tt rawfile.dat[i512,512]}: opens a raw binary data array (a 512 x 512
-short integer array in this case) and converts it on the fly into a
-temporary FITS format image in memory which can then be read with any
-other CFITSIO routine.
-
-\item
-{\tt myfile.fits.gz}: if this is the name of a new output file, the '.gz'
-suffix will cause it to be compressed in gzip format when it is written to
-disk.
-
-\item
-{\tt myfile.fits.gz[events, 2]}:  opens and uncompresses the gzipped file
-myfile.fits then moves to the extension with the keywords EXTNAME
-= 'EVENTS' and EXTVER = 2.
-
-\item
-{\tt -}:  a dash (minus sign) signifies that the input file is to be read
-from the stdin file stream, or that the output file is to be written to
-the stdout stream.  See also the stream:// driver which provides a
-more efficient, but more restricted method of reading or writing to
-the stdin or stdout streams.
-
-\item
-{\tt ftp://legacy.gsfc.nasa.gov/test/vela.fits}:  FITS files in any ftp
-archive site on the Internet may be directly opened with read-only
-access.
-
-\item
-{\tt http://legacy.gsfc.nasa.gov/software/test.fits}: any valid URL to a
-FITS file on the Web may be opened with read-only access.
-
-\item
-{\tt root://legacy.gsfc.nasa.gov/test/vela.fits}: similar to ftp access
-except that it provides write as well as read access to the files
-across the network. This uses the root protocol developed at CERN.
-
-\item
-{\tt shmem://h2[events]}: opens the FITS file in a shared memory segment and
-moves to the EVENTS extension.
-
-\item
-{\tt mem://}:  creates a scratch output file in core computer memory.  The
-resulting 'file' will disappear when the program exits, so this
-is mainly useful for testing purposes when one does not want a
-permanent copy of the output file.
-
-\item
-{\tt myfile.fits[3; Images(10)]}: opens a copy of the image contained in the
-10th row of the 'Images' column in the binary table in the 3th extension
-of the FITS file.  The virtual file that is opened by the application just
-contains this single image in the primary array.
-
-\item
-{\tt myfile.fits[1:512:2, 1:512:2]}: opens a section of the input image
-ranging from the 1st to the 512th pixel in  X and Y, and selects every
-second pixel in both dimensions, resulting in a 256 x 256 pixel input image
-in this case.
-
-\item
-{\tt myfile.fits[EVENTS][col Rad = sqrt(X**2 + Y**2)]}:  creates and opens
-a virtual file on the fly that is identical to
-myfile.fits except that it will contain a new column in the EVENTS
-extension called 'Rad' whose value is computed using the indicated
-expression which is a function of the values in the X and Y columns.
-
-\item
-{\tt myfile.fits[EVENTS][PHA > 5]}:  creates and opens a virtual FITS
-files that is identical to 'myfile.fits' except that the EVENTS table
-will only contain the rows that have values of the PHA column greater
-than 5.  In general, any arbitrary boolean expression using a C or
-Fortran-like syntax, which may combine AND and OR operators,
-may be used to select rows from a table.
-
-\item
-{\tt myfile.fits[EVENTS][bin (X,Y)=1,2048,4]}:  creates a temporary FITS
-primary array image which is computed on the fly by binning (i.e,
-computing the 2-dimensional histogram) of the values in the X and Y
-columns of the EVENTS extension.  In this case the X and Y coordinates
-range from 1 to 2048 and the image pixel size is 4 units in both
-dimensions, so the resulting image is 512 x 512 pixels in size.
-
-\item
-The final example combines many of these feature into one complex
-expression (it is broken into several lines for clarity):
-
-\begin{verbatim}
-   ftp://legacy.gsfc.nasa.gov/data/sample.fits.gz[EVENTS]
-   [col phacorr = pha * 1.1 - 0.3][phacorr >= 5.0 && phacorr <= 14.0]
-   [bin (X,Y)=32]
-\end{verbatim}
-In this case, CFITSIO (1) copies and uncompresses the FITS file from
-the ftp site on the legacy machine, (2) moves to the 'EVENTS'
-extension, (3) calculates a new column called 'phacorr', (4) selects
-the rows in the table that have phacorr in the range 5 to 14, and
-finally (5) bins the remaining rows on the X and Y column coordinates,
-using a pixel size = 32 to create a 2D image.  All this processing is
-completely transparent to the application program, which simply sees
-the final 2-D image in the primary array of the opened file.
-\end{itemize}
-
-The full extended CFITSIO FITS file name can contain several different
-components depending on the context.  These components are described in
-the following sections:
-
-\begin{verbatim}
-When creating a new file:
-   filetype://BaseFilename(templateName)[compress]
-
-When opening an existing primary array or image HDU:
-   filetype://BaseFilename(outName)[HDUlocation][ImageSection][pixFilter]
-
-When opening an existing table HDU:
-   filetype://BaseFilename(outName)[HDUlocation][colFilter][rowFilter][binSpec]
-\end{verbatim}
-The filetype, BaseFilename, outName, HDUlocation, ImageSection, and pixFilter
-components, if present, must be given in that order, but the colFilter,
-rowFilter, and binSpec specifiers may follow in any order.  Regardless
-of the order, however, the colFilter specifier, if present, will be
-processed first by CFITSIO, followed by the rowFilter specifier, and
-finally by the binSpec specifier.
-
-
-\section{Filetype}
-
-The type of file determines the medium on which the file is located
-(e.g., disk or network) and, hence, which internal device driver is used by
-CFITSIO to read and/or write the file.  Currently supported types are
-
-\begin{verbatim}
-        file://  - file on local magnetic disk (default)
-         ftp://  - a readonly file accessed with the anonymous FTP protocol.
-                   It also supports  ftp://username:password@hostname/...
-                   for accessing password-protected ftp sites.
-        http://  - a readonly file accessed with the HTTP protocol.  It
-                   supports username:password just like the ftp driver.
-                   Proxy HTTP servers are supported using the http_proxy
-                   environment variable (see following note).
-      stream://  - special driver to read an input FITS file from the stdin
-                   stream, and/or write an output FITS file to the stdout
-		   stream.  This driver is fragile and has limited
-		   functionality (see the following note).
-      gsiftp://  - access files on a computational grid using the gridftp
-                   protocol in the Globus toolkit (see following note).
-        root://  - uses the CERN root protocol for writing as well as
-                   reading files over the network (see following note).
-       shmem://  - opens or creates a file which persists in the computer's
-                   shared memory (see following note).
-         mem://  - opens a temporary file in core memory.  The file
-                   disappears when the program exits so this is mainly
-                   useful for test purposes when a permanent output file
-                   is not desired.
-\end{verbatim}
-If the filetype is not specified, then type file:// is assumed.
-The double slashes '//' are optional and may be omitted in most cases.
-
-
-\subsection{Notes about HTTP proxy servers}
-
-A proxy HTTP server may be used by defining the address (URL) and port
-number of the proxy server with the http\_proxy environment variable.
-For example
-
-\begin{verbatim}
-    setenv http_proxy http://heasarc.gsfc.nasa.gov:3128
-\end{verbatim}
-will cause CFITSIO to use port 3128 on the heasarc proxy server whenever
-reading a FITS file with HTTP.
-
-
-\subsection{Notes about the stream filetype driver}
-
-The stream driver can be used to efficiently read a FITS file from the stdin
-file stream or write a FITS to the stdout file stream.  However, because these
-input and output streams must be accessed sequentially, the FITS file reading or
-writing application must also read and write the file sequentially, at least
-within the tolerances described below.
-
-CFITSIO supports 2 different methods for accessing FITS files on the stdin and
-stdout streams.  The original method, which is invoked by specifying a dash
-character, "-", as the name of the file when opening or creating it, works by
-storing a complete copy of the entire FITS file in memory.  In this case, when
-reading from stdin, CFITSIO will copy the entire stream into memory before doing
-any processing of the file.  Similarly, when writing to stdout, CFITSIO will
-create a copy of the entire FITS file in memory, before finally flushing it out
-to  the stdout stream when the FITS file is closed.  Buffering the entire FITS
-file in this way allows the application to randomly access any part of the FITS
-file, in any order, but it also requires that the user have sufficient available
-memory (or virtual memory) to store the entire file, which may not be possible
-in the case of very large files.
-
-The newer stream filetype provides a more memory-efficient method of accessing
-FITS files on the stdin or stdout streams.  Instead of storing a copy of the
-entire FITS file in memory, CFITSIO only uses a set of internal  buffer which by
-default can store  40 FITS blocks, or about  100K bytes of the FITS file.  The
-application program must process the FITS file sequentially from beginning to
-end, within this 100K buffer.  Generally speaking the application  program must
-conform to the following restrictions:
-
-\begin{itemize}
-\item
-The program must finish reading or writing the header keywords
-before reading or writing any data in the HDU.
-\item
-The HDU can contain at most about 1400 header keywords.  This is the
-maximum that can fit in the nominal 40 FITS block buffer.  In principle,
-this limit could be increased by recompiling CFITSIO with a larger
-buffer limit, which is set by the NIOBUF parameter in fitsio2.h.
-\item
-The program must read or write the data in a sequential manner from the
-beginning to the end of the HDU.  Note that CFITSIO's internal
-100K buffer allows a little latitude in meeting this requirement.
-\item
-The program cannot move back to a previous HDU in the FITS file.
-\item
-Reading or writing of variable length array columns in binary tables is not
-supported on streams, because this requires moving back and forth between the
-fixed-length portion of the binary table and the following heap area where the
-arrays are actually stored.
-\item
-Reading or writing of tile-compressed images is not supported on streams,
-because the images are internally stored using variable length arrays.
-\end{itemize}
-
-
-\subsection{Notes about the gsiftp filetype}
-
-DEPENDENCIES: Globus toolkit (2.4.3 or higher) (GT) should be installed.
-There are two different ways to install GT:
-
-1) goto the globus toolkit web page www.globus.org and follow the
-   download and compilation instructions;
-
-2) goto the Virtual Data Toolkit web page http://vdt.cs.wisc.edu/
-   and follow the instructions (STRONGLY SUGGESTED);
-
-Once a globus client has been installed in your system with a specific flavour
-it is possible to compile and install the CFITSIO libraries.
-Specific configuration flags must be used:
-
-1)  --with-gsiftp[[=PATH]] Enable Globus Toolkit gsiftp protocol support
-    PATH=GLOBUS\_LOCATION i.e. the location of your globus installation
-
-2)  --with-gsiftp-flavour[[=PATH] defines the specific Globus flavour
-        ex. gcc32
-
-Both the flags must be used and it is mandatory to set  both the PATH and the
-flavour.
-
-USAGE: To access files on a gridftp server it is necessary to use a gsiftp prefix:
-
-example: gsiftp://remote\_server\_fqhn/directory/filename
-
-The gridftp driver uses a local buffer on a temporary file the file is located
-in the /tmp directory. If you have special permissions on /tmp or you do not have a /tmp
-directory, it is possible to force another location setting the GSIFTP\_TMPFILE environment
-variable (ex. export GSIFTP\_TMPFILE=/your/location/yourtmpfile).
-
-Grid FTP supports multi channel transfer. By default a single channel transmission is
-available. However, it is possible to modify this behavior setting the GSIFTP\_STREAMS
-environment variable (ex. export GSIFTP\_STREAMS=8).
-
-
-
-\subsection{Notes about the root filetype}
-
-The original rootd server can be obtained from:
-\verb-ftp://root.cern.ch/root/rootd.tar.gz-
-but, for it to work correctly with CFITSIO one has to use a modified
-version which supports a command to return the length of the file.
-This modified version is available in rootd subdirectory
-in the CFITSIO ftp area at
-
-\begin{verbatim}
-      ftp://legacy.gsfc.nasa.gov/software/fitsio/c/root/rootd.tar.gz.
-\end{verbatim}
-
-This small server is started either by inetd when a client requests a
-connection to a rootd server or by hand (i.e. from the command line).
-The rootd server works with the ROOT TNetFile class. It allows remote
-access to ROOT database files in either read or write mode. By default
-TNetFile assumes port 432 (which requires rootd to be started as root).
-To run rootd via inetd add the following line to /etc/services:
-
-\begin{verbatim}
-  rootd     432/tcp
-\end{verbatim}
-and to /etc/inetd.conf, add the following line:
-
-\begin{verbatim}
-  rootd stream tcp nowait root /user/rdm/root/bin/rootd rootd -i
-\end{verbatim}
-Force inetd to reread its conf file with \verb+kill -HUP <pid inetd>+.
-You can also start rootd by hand running directly under your private
-account (no root system privileges needed). For example to start
-rootd listening on port 5151 just type:   \verb+rootd -p 5151+
-Notice that no \& is needed. Rootd will go into background by itself.
-
-\begin{verbatim}
-  Rootd arguments:
-    -i                says we were started by inetd
-    -p port#          specifies a different port to listen on
-    -d level          level of debug info written to syslog
-                      0 = no debug (default)
-                      1 = minimum
-                      2 = medium
-                      3 = maximum
-\end{verbatim}
-Rootd can also be configured for anonymous usage (like anonymous ftp).
-To setup rootd to accept anonymous logins do the following (while being
-logged in as root):
-
-\begin{verbatim}
-   - Add the following line to /etc/passwd:
-
-     rootd:*:71:72:Anonymous rootd:/var/spool/rootd:/bin/false
-
-     where you may modify the uid, gid (71, 72) and the home directory
-     to suite your system.
-
-   - Add the following line to /etc/group:
-
-     rootd:*:72:rootd
-
-     where the gid must match the gid in /etc/passwd.
-
-   - Create the directories:
-
-     mkdir /var/spool/rootd
-     mkdir /var/spool/rootd/tmp
-     chmod 777 /var/spool/rootd/tmp
-
-     Where /var/spool/rootd must match the rootd home directory as
-     specified in the rootd /etc/passwd entry.
-
-   - To make writeable directories for anonymous do, for example:
-
-     mkdir /var/spool/rootd/pub
-     chown rootd:rootd /var/spool/rootd/pub
-\end{verbatim}
-That's all.  Several additional remarks:  you can login to an anonymous
-server either with the names "anonymous" or "rootd".  The password should
-be of type user@host.do.main. Only the @ is enforced for the time
-being.  In anonymous mode the top of the file tree is set to the rootd
-home directory, therefore only files below the home directory can be
-accessed.  Anonymous mode only works when the server is started via
-inetd.
-
-
-\subsection{Notes about the shmem filetype:}
-
-Shared memory files are currently supported on most Unix platforms,
-where the shared memory segments are managed by the operating system
-kernel and `live' independently of processes. They are not deleted (by
-default) when the process which created them terminates, although they
-will disappear if the system is rebooted.  Applications can create
-shared memory files in CFITSIO by calling:
-
-\begin{verbatim}
-   fit_create_file(&fitsfileptr, "shmem://h2", &status);
-\end{verbatim}
-where the root `file' names are currently restricted to be 'h0', 'h1',
-'h2', 'h3', etc., up to a maximum number defined by the the value of
-SHARED\_MAXSEG (equal to 16 by default).  This is a prototype
-implementation of the shared memory interface and a more robust
-interface, which will have fewer restrictions on the number of files
-and on their names, may be developed in the future.
-
-When opening an already existing FITS file in shared memory one calls
-the usual CFITSIO routine:
-
-\begin{verbatim}
-   fits_open_file(&fitsfileptr, "shmem://h7", mode, &status)
-\end{verbatim}
-The file mode can be READWRITE or READONLY just as with disk files.
-More than one process can operate on READONLY mode files at the same
-time.  CFITSIO supports proper file locking (both in READONLY and
-READWRITE modes), so calls to fits\_open\_file may be locked out until
-another other process closes the file.
-
-When an application is finished accessing a FITS file in a shared
-memory segment, it may close it  (and the file will remain in the
-system) with fits\_close\_file, or delete it with fits\_delete\_file.
-Physical deletion is postponed until the last process calls
-ffclos/ffdelt.  fits\_delete\_file tries to obtain a READWRITE lock on
-the file to be deleted, thus it can be blocked if the object was not
-opened in READWRITE mode.
-
-A shared memory management utility program called `smem', is included
-with the CFITSIO distribution.  It can be built by typing `make smem';
-then type `smem -h' to get a list of valid options.  Executing smem
-without any options causes it to list all the shared memory segments
-currently residing in the system and managed by the shared memory
-driver. To get a list of all the shared memory objects, run the system
-utility program `ipcs  [-a]'.
-
-
-\section{Base Filename}
-
-The base filename is the name of the file optionally including the
-director/subdirectory path, and in the case of `ftp', `http', and `root'
-filetypes, the machine identifier.  Examples:
-
-\begin{verbatim}
-    myfile.fits
-    !data.fits
-    /data/myfile.fits
-    fits.gsfc.nasa.gov/ftp/sampledata/myfile.fits.gz
-\end{verbatim}
-
-When creating a new output file on magnetic disk (of type file://) if
-the base filename begins with an exclamation point (!) then any
-existing file with that same basename will be deleted prior to creating
-the new FITS file.  Otherwise if the file to be created already exists,
-then CFITSIO will return an error and will not overwrite the existing
-file.  Note  that the exclamation point,  '!', is a special UNIX
-character, so if it is used  on the command line rather than entered at
-a task prompt, it must be  preceded by a backslash to force the UNIX
-shell to pass it verbatim to the application program.
-
-If the output disk file name ends with the suffix '.gz', then CFITSIO
-will compress the file using the gzip compression algorithm before
-writing it to disk.  This can reduce the amount of disk space used by
-the file.  Note that this feature requires that the uncompressed file
-be constructed in memory before it is compressed and written to disk,
-so it can fail if there is insufficient available memory.
-
-An input FITS file may be compressed with the gzip or Unix compress
-algorithms, in which case CFITSIO will uncompress the file on the fly
-into a temporary file (in memory or on disk).  Compressed files may
-only be opened with read-only permission.  When specifying the name of
-a compressed FITS file it is not necessary to append the file suffix
-(e.g., `.gz' or `.Z').  If CFITSIO cannot find the input file name
-without the suffix, then it will automatically search for a compressed
-file with the same root name.  In the case of reading ftp and http type
-files, CFITSIO generally looks for a compressed version of the file
-first, before trying to open the uncompressed file.  By default,
-CFITSIO copies (and uncompressed if necessary) the ftp or http FITS
-file into memory on the local machine before opening it.  This will
-fail if the local machine does not have enough memory to hold the whole
-FITS file, so in this case, the output filename specifier (see the next
-section) can be used to further control how CFITSIO reads ftp and http
-files.
-
-If the input file is an IRAF image file (*.imh file) then CFITSIO will
-automatically convert it on the fly into a virtual FITS image before it
-is opened by the application program.  IRAF images can only be opened
-with READONLY file access.
-
-Similarly, if the input file is a raw binary data array, then CFITSIO
-will convert it on the fly into a virtual FITS image with the basic set
-of required header keywords before it is opened by the application
-program (with READONLY access).  In this case the data type and
-dimensions of the image must be specified in square brackets following
-the filename (e.g. rawfile.dat[ib512,512]). The first character (case
-insensitive) defines the data type of the array:
-
-\begin{verbatim}
-     b         8-bit unsigned byte
-     i        16-bit signed integer
-     u        16-bit unsigned integer
-     j        32-bit signed integer
-     r or f   32-bit floating point
-     d        64-bit floating point
-\end{verbatim}
-An optional second character specifies the byte order of the array
-values: b or B indicates big endian (as in FITS files and the native
-format of SUN UNIX workstations and Mac PCs) and l or L indicates
-little endian (native format of DEC OSF workstations and IBM PCs).  If
-this character is omitted then the array is assumed to have the native
-byte order of the local machine.  These data type characters are then
-followed by a series of one or more integer values separated by commas
-which define the size of each dimension of the raw array.  Arrays with
-up to 5 dimensions are currently supported.  Finally, a byte offset to
-the position of the first pixel in the data file may be specified by
-separating it with a ':' from the last dimension value.  If omitted, it
-is assumed that the offset = 0.  This parameter may be used to skip
-over any header information in the file that precedes the binary data.
-Further examples:
-
-\begin{verbatim}
-  raw.dat[b10000]           1-dimensional 10000 pixel byte array
-  raw.dat[rb400,400,12]     3-dimensional floating point big-endian array
-  img.fits[ib512,512:2880]  reads the 512 x 512 short integer array in
-                            a FITS file, skipping over the 2880 byte header
-\end{verbatim}
-
-One special case of input file is where the filename = `-' (a dash or
-minus sign) or 'stdin' or 'stdout', which signifies that the input file
-is to be read from the stdin stream, or written to the stdout stream if
-a new output file is being created.  In the case of reading from stdin,
-CFITSIO first copies the whole stream into a temporary FITS file (in
-memory or on disk), and subsequent reading of the FITS file occurs in
-this copy.  When writing to stdout, CFITSIO first constructs the whole
-file in memory (since random access is required), then flushes it out
-to the stdout stream when the file is closed.  In addition, if the
-output filename = '-.gz' or 'stdout.gz' then it will be gzip compressed
-before being written to stdout.
-
-This ability to read and write on the stdin and stdout steams allows
-FITS files to be piped between tasks in memory rather than having to
-create temporary intermediate FITS files on disk.  For example if task1
-creates an output FITS file, and task2 reads an input FITS file, the
-FITS file may be piped between the 2 tasks by specifying
-
-\begin{verbatim}
-   task1 - | task2 -
-\end{verbatim}
-where the vertical bar is the Unix piping symbol.  This assumes that the 2
-tasks read the name of the FITS file off of the command line.
-
-
-\section{Output File Name when Opening an Existing File}
-
-An optional output filename may be specified in parentheses immediately
-following the base file name to be opened.  This is mainly useful in
-those cases where CFITSIO creates a temporary copy of the input FITS
-file before it is opened and passed to the application program.  This
-happens by default when opening a network FTP or HTTP-type file, when
-reading a compressed FITS file on a local disk, when reading from the
-stdin stream, or when a column filter, row filter, or binning specifier
-is included as part of the input file specification.  By default this
-temporary file is created in memory.  If there is not enough memory to
-create the file copy, then CFITSIO will exit with an error.   In these
-cases one can force a permanent file to be created on disk, instead of
-a temporary file in memory, by supplying the name in parentheses
-immediately following the base file name.  The output filename can
-include the '!' clobber flag.
-
-Thus, if the input filename to CFITSIO is:
-\verb+file1.fits.gz(file2.fits)+
-then CFITSIO will uncompress `file1.fits.gz' into the local disk file
-`file2.fits' before opening it.  CFITSIO does not automatically delete
-the output file, so it will still exist after the application program
-exits.
-
-The output filename "mem://" is also allowed, which will write the
-output file into memory, and also allow write access to the file.  This
-'file' will disappear when it is closed, but this may be useful for
-some applications which only need to modify a temporary copy of the file.
-
-In some cases, several different temporary FITS files will be created
-in sequence, for instance, if one opens a remote file using FTP, then
-filters rows in a binary table extension, then create an image by
-binning a pair of columns.  In this case, the remote file will be
-copied to a temporary local file, then a second temporary file will be
-created containing the filtered rows of the table, and finally a third
-temporary file containing the binned image will be created.  In cases
-like this where multiple files are created, the outfile specifier will
-be interpreted the name of the final file as described below, in descending
-priority:
-
-\begin{itemize}
-\item
-as the name of the final image file if an image within a single binary
-table cell is opened or if an image is created by binning a table column.
-\item
-as the name of the file containing the filtered table if a column filter
-and/or a row filter are specified.
-\item
-as the name of the local copy of the remote FTP or HTTP file.
-\item
-as the name of the uncompressed version of the FITS file, if a
-compressed FITS file on local disk has been opened.
-\item
-otherwise, the output filename is ignored.
-\end{itemize}
-
-The output file specifier is useful when reading FTP or HTTP-type
-FITS files since it can be used to create a local disk copy of the file
-that can be reused in the future.  If the output file name = `*' then a
-local file with the same name as the network file will be created.
-Note that CFITSIO will behave differently depending on whether the
-remote file is compressed or not as shown by the following examples:
-\begin{itemize}
-\item
-\verb+ftp://remote.machine/tmp/myfile.fits.gz(*)+ - the remote compressed
-file is copied to the local compressed file `myfile.fits.gz', which
-is then uncompressed in local memory before being opened and passed
-to the application program.
-
-\item
-\verb+ftp://remote.machine/tmp/myfile.fits.gz(myfile.fits)+ - the
-remote compressed file is copied and uncompressed into the local file
-`myfile.fits'.  This example requires less local memory than the
-previous example since the file is uncompressed on disk instead of in
-memory.
-
-\item
-\verb+ftp://remote.machine/tmp/myfile.fits(myfile.fits.gz)+ - this will
-usually produce an error since CFITSIO itself cannot compress files.
-\end{itemize}
-
-The exact behavior of CFITSIO in the latter case depends on the type of
-ftp server running on the remote machine and how it is configured.  In
-some cases, if the file `myfile.fits.gz' exists on the remote machine,
-then the server will copy it to the local machine.  In other cases the
-ftp server will automatically create and transmit a compressed version
-of the file if only the uncompressed version exists.  This can get
-rather confusing, so users should use a certain amount of caution when
-using the output file specifier with FTP or HTTP file types, to make
-sure they get the behavior that they expect.
-
-
-\section{Template File Name when Creating a New File}
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described in the following Template Files chapter.
-
-
-\section{Image Tile-Compression Specification}
-
-When specifying the name of the output FITS file to be created, the
-user can indicate that images should be written in tile-compressed
-format (see section 5.5, ``Primary Array or IMAGE Extension I/O
-Routines'') by enclosing the compression parameters in square brackets
-following the root disk file name.  Here are some examples of the
-syntax for specifying tile-compressed output images:
-
-\begin{verbatim}
-    myfile.fit[compress]    - use Rice algorithm and default tile size
-
-    myfile.fit[compress GZIP] - use the specified compression algorithm;
-    myfile.fit[compress Rice]     only the first letter of the algorithm
-    myfile.fit[compress PLIO]     name is required.
-
-    myfile.fit[compress Rice 100,100]   - use 100 x 100 pixel tile size
-    myfile.fit[compress Rice 100,100;2] - as above, and use noisebits = 2
-\end{verbatim}
-
-
-\section{HDU Location Specification}
-
-The optional HDU location specifier defines which HDU (Header-Data
-Unit, also known as an `extension') within the FITS file to initially
-open.  It must immediately follow the base file name (or the output
-file name if present).  If it is not specified then the first HDU (the
-primary array) is opened.  The HDU location specifier is required if
-the colFilter, rowFilter, or binSpec specifiers are present, because
-the primary array is not a valid HDU for these operations. The HDU may
-be specified either by absolute position number, starting with 0 for
-the primary array, or by reference to the HDU name, and optionally, the
-version number and the HDU type of the desired extension.  The location
-of an image within a single cell of a binary table may also be
-specified, as described below.
-
-The absolute position of the extension is specified either by enclosed
-the number in square brackets (e.g., `[1]' = the first extension
-following the primary array) or by preceded the number with a plus sign
-(`+1').  To specify the HDU by name, give the name of the desired HDU
-(the value of the EXTNAME or HDUNAME keyword) and optionally the
-extension version number (value of the EXTVER keyword) and the
-extension type (value of the XTENSION keyword: IMAGE, ASCII or TABLE,
-or BINTABLE), separated by commas and all enclosed in square brackets.
-If the value of EXTVER and XTENSION are not specified, then the first
-extension with the correct value of EXTNAME is opened. The extension
-name and type are not case sensitive, and the extension type may be
-abbreviated to a single letter (e.g., I = IMAGE extension or primary
-array, A or T = ASCII table extension, and B = binary table BINTABLE
-extension).   If the HDU location specifier is equal to `[PRIMARY]' or
-`[P]', then the primary array (the first HDU) will be opened.
-
-An optional pound sign character ("\#") may be appended to the extension
-name or number to signify that any other extensions in the file should
-be ignored during any subsequent file filtering operations.  For example,
-when doing row filtering operations on a table extension, CFITSIO normally
-creates a copy of the filtered table in memory, along with a verbatim
-copy of all the other extensions in the input FITS file.  If the pound
-sign is appended to the table extension name, then only that extension,
-and none of the other extensions in the file, will by copied to memory,
-as in the following example:
-
-\begin{verbatim}
-   myfile.fit[events#][TIME > 10000]
-\end{verbatim}
-
-FITS images are most commonly stored in the primary array or an image
-extension, but images can also be stored as a vector in a single cell
-of a binary table (i.e. each row of the vector column contains a
-different image).  Such an image can be opened with CFITSIO by
-specifying the desired column  name and the row number after the binary
-table HDU specifier as shown in the following examples. The column name
-is separated from the HDU specifier by a semicolon and the row number
-is enclosed in parentheses.  In this case CFITSIO copies the image from
-the table cell into a temporary primary array before it is opened.  The
-application program then just sees the image in the primary array,
-without any extensions.  The particular row to be opened may be
-specified either by giving an absolute integer row number (starting
-with 1 for the first row), or by specifying a boolean expression that
-evaluates to TRUE for the desired row.  The first row that satisfies
-the expression will be used.  The row selection expression has the same
-syntax as described in the Row Filter Specifier section, below.
-
- Examples:
-
-\begin{verbatim}
-   myfile.fits[3] - open the 3rd HDU following the primary array
-   myfile.fits+3  - same as above, but using the FTOOLS-style notation
-   myfile.fits[EVENTS] - open the extension that has EXTNAME = 'EVENTS'
-   myfile.fits[EVENTS, 2]  - same as above, but also requires EXTVER = 2
-   myfile.fits[events,2,b] - same, but also requires XTENSION = 'BINTABLE'
-   myfile.fits[3; images(17)] - opens the image in row 17 of the 'images'
-                                column in the 3rd extension of the file.
-   myfile.fits[3; images(exposure > 100)] - as above, but opens the image
-                   in the first row that has an 'exposure' column value
-                   greater than 100.
-\end{verbatim}
-
-
-\section{Image Section}
-
-A virtual file containing a rectangular subsection of an image can be
-extracted and opened by specifying the range of pixels (start:end)
-along each axis to be extracted from the original image.  One can also
-specify an optional pixel increment (start:end:step) for each axis of
-the input image.  A pixel step = 1 will be assumed if it is not
-specified.  If the start pixel is larger then the end pixel, then the
-image will be flipped (producing a mirror image) along that dimension.
-An asterisk, '*', may be used to specify the entire range of an axis,
-and '-*' will flip the entire axis. The input image can be in the
-primary array, in an image extension, or contained in a vector cell of
-a binary table. In the later 2 cases the extension name or number must
-be specified before the image section specifier.
-
- Examples:
-
-\begin{verbatim}
-  myfile.fits[1:512:2, 2:512:2] -  open a 256x256 pixel image
-              consisting of the odd numbered columns (1st axis) and
-              the even numbered rows (2nd axis) of the image in the
-              primary array of the file.
-
-  myfile.fits[*, 512:256] - open an image consisting of all the columns
-              in the input image, but only rows 256 through 512.
-              The image will be flipped along the 2nd axis since
-              the starting pixel is greater than the ending pixel.
-
-  myfile.fits[*:2, 512:256:2] - same as above but keeping only
-              every other row and column in the input image.
-
-  myfile.fits[-*, *] - copy the entire image, flipping it along
-              the first axis.
-
-  myfile.fits[3][1:256,1:256] - opens a subsection of the image that
-              is in the 3rd extension of the file.
-
-  myfile.fits[4; images(12)][1:10,1:10] - open an image consisting
-	      of the first 10 pixels in both dimensions. The original
-	      image resides in the 12th row of the 'images' vector
-	      column in the table in the 4th extension of the file.
-\end{verbatim}
-
-When CFITSIO opens an image section it first creates a temporary file
-containing the image section plus a copy of any other HDUs in the
-file. (If a `\#' character is appended to the name or number of the
-image HDU, as in  "myfile.fits[1\#][1:200,1:200]", then the other
-HDUs in the input file will not be copied into memory).
-This temporary file is then opened by the application program,
-so it is not possible to write to or modify the input file when
-specifying an image section.  Note that CFITSIO automatically updates
-the world coordinate system keywords in the header of the image
-section, if they exist, so that the coordinate associated with each
-pixel in the image section will be computed correctly.
-
-
-\section{Image Transform Filters}
-
-CFITSIO can apply a user-specified mathematical function to the value
-of every pixel in a FITS image, thus creating a new virtual image
-in computer memory that is then opened and read by the application
-program.  The original FITS image is not modified by this process.
-
-The image transformation specifier is appended to the input
-FITS file name and is enclosed in square brackets.  It begins with the
-letters 'PIX' to distinguish it from other types of FITS file filters
-that are recognized by CFITSIO.  The image transforming function may
-use any of the mathematical operators listed in the following
-'Row Filtering Specification' section of this document.
-Some examples of  image transform filters are:
-
-\begin{verbatim}
- [pix X * 2.0]               - multiply each pixel by 2.0
- [pix sqrt(X)]               - take the square root of each pixel
- [pix X + #ZEROPT            - add the value of the ZEROPT keyword
- [pix X>0 ? log10(X) : -99.] - if the pixel value is greater
-                               than 0, compute the base 10 log,
-                               else set the pixel = -99.
-\end{verbatim}
-Use the letter 'X' in the expression to represent the current pixel value
-in the image.  The expression is evaluated
-independently for each pixel in the image and may be a function of 1) the
-original pixel value, 2) the value of other pixels in the image at
-a given relative offset from the position of the pixel that is being
-evaluated, and 3) the value of
-any header keywords.  Header keyword values are represented
-by the name of the keyword preceded by the '\#' sign.
-
-
-To access the the value of adjacent pixels in the image,
-specify the (1-D) offset from the current pixel in curly brackets.
-For example
-
-\begin{verbatim}
- [pix  (x{-1} + x + x{+1}) / 3]
-\end{verbatim}
-will replace each pixel value with the running mean of the values of that
-pixel and it's 2 neighboring pixels.  Note that in this notation the image
-is treated as a 1-D array, where each row of the image (or higher dimensional
-cube) is appended one after another in one long array of pixels.
-It is possible to refer to pixels
-in the rows above or below the current pixel by using the value of the
-NAXIS1 header keyword.  For example
-
-\begin{verbatim}
- [pix (x{-#NAXIS1} + x + x{#NAXIS1}) / 3]
-\end{verbatim}
-will compute the mean of each image pixel and the pixels immediately
-above and below it in the adjacent rows of the image.
-The following more complex example
-creates a smoothed virtual image where each pixel
-is a 3 x 3 boxcar average of the input image pixels:
-
-\begin{verbatim}
-  [pix (X + X{-1} + X{+1}
-      + X{-#NAXIS1} + X{-#NAXIS1 - 1} + X{-#NAXIS1 + 1}
-      + X{#NAXIS1} + X{#NAXIS1 - 1} + X{#NAXIS1 + 1}) / 9.]
-\end{verbatim}
-If the pixel offset
-extends beyond the first or last pixel in the image, the function will
-evaluate to undefined, or NULL.
-
-For  complex  or commonly used image filtering operations,
-one  can  write the expression into an external text  file and
-then import it  into the
-filter using  the syntax '[pix @filename.txt]'.   The mathematical
-expression can
-extend over multiple lines of text in the  file.
-Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-By default, the datatype of the resulting image will be the same as
-the original image, but one may force a different datatype by appended
-a code letter to the 'pix' keyword:
-
-\begin{verbatim}
-      pixb  -  8-bit byte    image with BITPIX =   8
-      pixi  - 16-bit integer image with BITPIX =  16
-      pixj  - 32-bit integer image with BITPIX =  32
-      pixr  - 32-bit float   image with BITPIX = -32
-      pixd  - 64-bit float   image with BITPIX = -64
-\end{verbatim}
-Also by default, any other HDUs in the input file will be copied without
-change to the
-output virtual FITS file, but one may discard the other HDUs by adding
-the number '1' to the 'pix' keyword (and following any optional datatype code
-letter).  For example:
-
-\begin{verbatim}
-     myfile.fits[3][pixr1  sqrt(X)]
-\end{verbatim}
-will create a virtual FITS file containing only a primary array image
-with 32-bit floating point pixels that have a value equal to the square
-root of the pixels in the image that is in the 3rd extension
-of the 'myfile.fits' file.
-
-
-
-\section{Column and Keyword Filtering Specification}
-
-The optional column/keyword filtering specifier is used to modify the
-column structure and/or the header keywords in the HDU that was
-selected with the previous HDU location specifier. This filtering
-specifier must be enclosed in square brackets and can be distinguished
-from a general row filter specifier (described below) by the fact that
-it begins with the string 'col ' and is not immediately followed by an
-equals sign.  The original file is not changed by this filtering
-operation, and instead the modifications are made on a copy of the
-input FITS file (usually in memory), which also contains a copy of all
-the other HDUs in the file.  (If a `\#' character is appended to the name
-or number of the
-table HDU then only the primary array, and none of the other
-HDUs in the input file will be copied into memory).
-This temporary file is passed to the
-application program and will persist only until the file is closed or
-until the program exits, unless the outfile specifier (see above) is
-also supplied.
-
-The column/keyword filter can be used to perform the following
-operations.  More than one operation may be specified by separating
-them with commas or semi-colons.
-
-\begin{itemize}
-
-\item
-Copy only a specified list of columns columns to the filtered input file.
-The list of column name should be separated by semi-colons.  Wild card
-characters may be used in the column names to match multiple columns.
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table
-except the explicitly deleted columns will appear in the filtered
-table (i.e., there is no need to explicitly list the columns to
-be included if any columns are being deleted).
-
-\item
-Delete a column or keyword by listing the name preceded by a minus sign
-or an exclamation mark (!), e.g., '-TIME' will delete the TIME column
-if it exists, otherwise the TIME keyword.  An error is returned if
-neither a column nor keyword with this name exists.  Note  that the
-exclamation point,  '!', is a special UNIX character, so if it is used
-on the command line rather than entered at a task prompt, it must be
-preceded by a backslash to force the UNIX shell to ignore it.
-
-\item
-Rename an existing column or keyword with the syntax 'NewName ==
-OldName'.  An error is returned if neither a column nor keyword with
-this name exists.
-
-\item
-Append a new column or keyword to the table.  To create a column,
-give the new name, optionally followed by the data type in parentheses,
-followed by a single equals sign and an  expression to be used to
-compute the value (e.g., 'newcol(1J) = 0' will create a new 32-bit
-integer column called 'newcol' filled with zeros).  The data type is
-specified using the same syntax that is allowed for the value of the
-FITS TFORMn keyword (e.g., 'I', 'J', 'E', 'D', etc. for binary tables,
-and 'I8', F12.3', 'E20.12', etc. for ASCII tables).  If the data type is
-not specified then an appropriate data type will be chosen depending on
-the form of the expression (may be a character string, logical, bit, long
-integer, or double column). An appropriate vector count (in the case
-of binary tables) will also be added if not explicitly specified.
-
-When creating a new keyword, the keyword name must be preceded by a
-pound sign '\#', and the expression must evaluate to a scalar
-(i.e., cannot have a column name in the expression).  The comment
-string for the keyword may be specified in parentheses immediately
-following the keyword name (instead of supplying a data type as in
-the case of creating a new column).  If the keyword name ends with a
-pound sign '\#', then cfitsio will substitute the number of the
-most recently referenced column for the \# character .
-This is especially useful when writing
-a column-related keyword like TUNITn for a newly created column,
-as shown in the following examples.
-
-\item
-Recompute (overwrite) the values in an existing column or keyword by
-giving the name followed by an equals sign and an arithmetic
-expression.
-\end{itemize}
-
-The expression that is used when appending or recomputing columns or
-keywords can be arbitrarily complex and may be a function of other
-header keyword values and other columns (in the same row).  The full
-syntax and available functions for the expression are described below
-in the row filter specification section.
-
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table
-except the explicitly deleted columns will appear in the filtered
-table.  If no columns to be deleted are specified, then only the
-columns that are explicitly listed will be included in the filtered
-output table.  To include all the columns, add the '*' wildcard
-specifier at the end of the list, as shown in the examples.
-
-For  complex  or commonly used operations,  one  can  place the
-operations into an external text  file and import it  into the  column
-filter using  the syntax '[col @filename.txt]'.   The operations can
-extend over multiple lines of the  file, but multiple operations must
-still be separated by semicolons.   Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-Examples:
-
-\begin{verbatim}
-   [col Time; rate]              - only the Time and rate columns will
-                                   appear in the filtered input file.
-
-   [col Time, *raw]              - include the Time column and any other
-                                   columns whose name ends with 'raw'.
-
-   [col -TIME; Good == STATUS]   - deletes the TIME column and
-                                   renames the status column to 'Good'
-
-   [col PI=PHA * 1.1 + 0.2; #TUNIT#(column units) = 'counts';*]
-                                 - creates new PI column from PHA values
-                                   and also writes the TUNITn keyword
-                                   for the new column.  The final '*'
-                                   expression means preserve all the
-                                   columns in the input table in the
-                                   virtual output table;  without the '*'
-                                   the output table would only contain
-                                   the single 'PI' column.
-
-   [col rate = rate/exposure; TUNIT#(&) = 'counts/s';*]
-                                 - recomputes the rate column by dividing
-                                   it by the EXPOSURE keyword value. This
-                                   also modifies the value of the TUNITn
-                                   keyword for this column. The use of the
-                                   '&' character for the keyword comment
-                                   string means preserve the existing
-                                   comment string for that keyword. The
-                                   final '*' preserves all the columns
-                                   in the input table in the virtual
-                                   output table.
-\end{verbatim}
-
-
-\section{Row Filtering Specification}
-
-    When entering the name of a FITS table that is to be opened by a
-    program, an optional row filter may be specified to select a subset
-    of the rows in the table.  A temporary new FITS file is created on
-    the fly which contains only those rows for which the row filter
-    expression evaluates to true.  The primary array and any other
-    extensions in the input file are also copied to the temporary
-    file.
-(If a `\#' character is appended to the name
-or number of the
-table HDU then only the primary array, and none of the other
-HDUs in the input file will be copied into the temporary file).
-    The original FITS file is closed and the new virtual file
-    is opened by the application program.  The row filter expression is
-    enclosed in square brackets following the file name and extension
-    name (e.g., 'file.fits[events][GRADE==50]'  selects only those rows
-    where the GRADE column value equals 50).   When dealing with tables
-    where each row has an associated time and/or 2D spatial position,
-    the row filter expression can also be used to select rows based on
-    the times in a Good Time Intervals (GTI) extension, or on spatial
-    position as given in a SAO-style region file.
-
-
-\subsection{General Syntax}
-
-    The row filtering  expression can be an arbitrarily  complex series
-    of operations performed  on constants,  keyword values,  and column
-    data taken from the specified FITS TABLE extension.  The expression
-    must evaluate to a boolean  value for each row  of the table, where
-    a value of FALSE means that the row will be excluded.
-
-    For complex or commonly  used filters, one can place the expression
-    into a text file and import it into the row filter using the syntax
-    '[@filename.txt]'.  The expression can be  arbitrarily complex and
-    extend over multiple lines of the file.  Any lines in the external
-    text file that begin with 2 slash characters ('//') will be ignored
-    and may be used to add comments into the file.
-
-    Keyword and   column data  are referenced by   name.  Any  string of
-    characters not surrounded by    quotes (ie, a constant  string)   or
-    followed by   an open parentheses (ie,   a  function name)   will be
-    initially interpreted   as a column  name and  its contents for the
-    current row inserted into the expression.  If no such column exists,
-    a keyword of that  name will be searched for  and its value used, if
-    found.  To force the  name to be  interpreted as a keyword (in case
-    there is both a column and keyword with the  same name), precede the
-    keyword name with a single pound sign, '\#', as in '\#NAXIS2'.  Due to
-    the generalities of FITS column and  keyword names, if the column or
-    keyword name  contains a space or a  character which might appear as
-    an arithmetic  term then enclose  the  name in '\$'  characters as in
-    \$MAX PHA\$ or \#\$MAX-PHA\$.  Names are case insensitive.
-
-    To access a table entry in a row other  than the current one, follow
-    the  column's name  with  a row  offset  within  curly  braces.  For
-    example, 'PHA\{-3\}' will evaluate to the value  of column PHA, 3 rows
-    above  the  row currently  being processed.   One  cannot specify an
-    absolute row number, only a relative offset.  Rows that fall outside
-    the table will be treated as undefined, or NULLs.
-
-    Boolean   operators can be  used in  the expression  in either their
-    Fortran or C forms.  The following boolean operators are available:
-
-\begin{verbatim}

-\end{verbatim}
-Three different random number functions are provided:  random(), with
-no arguments, produces a uniform random deviate between 0 and 1;
-randomn(), also with no arguments, produces a normal (Gaussian) random
-deviate  with zero mean and unit standard deviation; randomp(x)
-produces a Poisson random deviate whose expected number of counts is
-X.  X may be any positive real number of expected counts, including
-fractional values, but the return value is an integer.
-
-When the random functions are used in a vector expression, by default
-the same random value will be used when evaluating each element of the vector.
-If different random numbers are desired, then the name of a vector
-column should be supplied as the single argument to the random
-function (e.g., "flux + 0.1 * random(flux)", where "flux' is the
-name of a vector column).  This will create a vector of
-random numbers that will be used in sequence when evaluating each
-element of the vector expression.
-
-An alternate syntax for the min and max functions  has only a single
-argument which  should be  a  vector value (see  below).  The result
-will be the minimum/maximum element contained within the vector.
-
-The accum(x) function forms the cumulative sum of x, element by element.
-Vector columns are supported simply by performing the summation process
-through all the values.  Null values are treated as 0.  The seqdiff(x)
-function forms the sequential difference of x, element by element.
-The first value of seqdiff is the first value of x.  A single null
-value in x causes a pair of nulls in the output.  The seqdiff and
-accum functions are functional inverses, i.e., seqdiff(accum(x)) == x
-as long as no null values are present.
-
-In the if-then-else expression, "b?x:y", b is an explicit boolean
-value or expression.  There is no automatic type conversion from
-numeric to boolean values, so one needs to use "iVal!=0" instead of
-merely "iVal" as the boolean argument. x and y can be any scalar data
-type (including string).
-
-The angsep function computes the angular separation in degrees
-between 2 celestial positions, where the first 2 parameters
-give the RA-like and Dec-like coordinates (in decimal degrees)
-of the first position, and the 3rd and 4th parameters give the
-coordinates of the second position.
-
-The substring function strmid(S,P,N) extracts a substring from S,
-starting at string position P, with a substring length N.  The first
-character position in S is labeled as 1. If P is 0, or refers to a
-position beyond the end of S, then the extracted substring will be
-NULL.  S, P, and N may be functions of other columns.
-
-The string search function strstr(S,R) searches for the first occurrence
-of the substring R in S.  The result is an integer, indicating the
-character position of the first match (where 1 is the first character
-position of S).  If no match is found, then strstr() returns a NULL
-value.
-
-The  following  type  casting  operators  are  available,  where the
-inclosing parentheses are required and taken  from  the  C  language
-usage. Also, the integer to real casts values to double precision:
-
-\begin{verbatim}
-                "real to integer"    (int) x     (INT) x
-                "integer to real"    (float) i   (FLOAT) i
-\end{verbatim}
-
-    In addition, several constants are built in  for  use  in  numerical
-    expressions:
-
-
-\begin{verbatim}
-        #pi              3.1415...      #e             2.7182...
-        #deg             #pi/180        #row           current row number
-        #null         undefined value   #snull         undefined string
-\end{verbatim}
-
-    A  string constant must  be enclosed  in quotes  as in  'Crab'.  The
-    "null" constants  are useful for conditionally  setting table values
-    to a NULL, or undefined, value (eg., "col1==-99 ? \#NULL : col1").
-
-    There is also a function for testing if  two  values  are  close  to
-    each  other,  i.e.,  if  they are "near" each other to within a user
-    specified tolerance. The  arguments,  value\_1  and  value\_2  can  be
-    integer  or  real  and  represent  the two values who's proximity is
-    being tested to be within the specified tolerance, also  an  integer
-    or real:
-
-\begin{verbatim}
-                    near(value_1, value_2, tolerance)
-\end{verbatim}
-    When  a  NULL, or undefined, value is encountered in the FITS table,
-    the expression will evaluate to NULL unless the undefined  value  is
-    not   actually   required  for  evaluation,  e.g. "TRUE  .or.  NULL"
-    evaluates to TRUE. The  following  two  functions  allow  some  NULL
-    detection  and  handling:
-
-\begin{verbatim}
-         "a null value?"              ISNULL(x)
-         "define a value for null"    DEFNULL(x,y)
-\end{verbatim}
-    The former
-    returns a boolean value of TRUE if the  argument  x  is  NULL.   The
-    later  "defines"  a  value  to  be  substituted  for NULL values; it
-    returns the value of x if x is not NULL, otherwise  it  returns  the
-    value of y.
-
-
-
-
-\subsection{Bit Masks}
-
-    Bit  masks can be used to select out rows from bit columns (TFORMn =
-    \#X) in FITS files. To represent the mask,  binary,  octal,  and  hex
-    formats are allowed:
-
-
-\begin{verbatim}
-                 binary:   b0110xx1010000101xxxx0001
-                 octal:    o720x1 -> (b111010000xxx001)
-                 hex:      h0FxD  -> (b00001111xxxx1101)
-\end{verbatim}
-
-    In  all  the  representations, an x or X is allowed in the mask as a
-    wild card. Note that the x represents a  different  number  of  wild
-    card  bits  in  each  representation.  All  representations are case
-    insensitive.
-
-    To construct the boolean expression using the mask  as  the  boolean
-    equal  operator  described above on a bit table column. For example,
-    if you had a 7 bit column named flags in a  FITS  table  and  wanted
-    all  rows  having  the bit pattern 0010011, the selection expression
-    would be:
-
-
-\begin{verbatim}
-                            flags == b0010011
-    or
-                            flags .eq. b10011
-\end{verbatim}
-
-    It is also possible to test if a range of bits is  less  than,  less
-    than  equal,  greater  than  and  greater than equal to a particular
-    boolean value:
-
-
-\begin{verbatim}
-                            flags <= bxxx010xx
-                            flags .gt. bxxx100xx
-                            flags .le. b1xxxxxxx
-\end{verbatim}
-
-    Notice the use of the x bit value to limit the range of  bits  being
-    compared.
-
-    It  is  not necessary to specify the leading (most significant) zero
-    (0) bits in the mask, as shown in the second expression above.
-
-    Bit wise AND, OR and NOT operations are  also  possible  on  two  or
-    more  bit  fields  using  the  '\&'(AND),  '$|$'(OR),  and the '!'(NOT)
-    operators. All of these operators result in a bit  field  which  can
-    then be used with the equal operator. For example:
-
-
-\begin{verbatim}
-                          (!flags) == b1101100
-                          (flags & b1000001) == bx000001
-\end{verbatim}
-
-    Bit  fields can be appended as well using the '+' operator.  Strings
-    can be concatenated this way, too.
-
-
-\subsection{Vector Columns}
-
-    Vector columns can also be used  in  building  the  expression.   No
-    special  syntax  is required if one wants to operate on all elements
-    of the vector.  Simply use the column name as for a  scalar  column.
-    Vector  columns  can  be  freely  intermixed  with scalar columns or
-    constants in virtually all expressions.  The result will be  of  the
-    same dimension as the vector.  Two vectors in an expression, though,
-    need to  have  the  same  number  of  elements  and  have  the  same
-    dimensions.
-
-    Arithmetic and logical operations are all performed on an element by
-    element basis.  Comparing two vector columns,  eg  "COL1  ==  COL2",
-    thus  results  in  another vector of boolean values indicating which
-    elements of the two vectors are equal.
-
-    Eight functions are available that operate on a vector and return a
-    scalar result:
-
-\begin{verbatim}
-    "minimum"      MIN(V)          "maximum"               MAX(V)
-    "average"      AVERAGE(V)      "median"                MEDIAN(V)
-    "summation"    SUM(V)          "standard deviation"    STDDEV(V)
-    "# of values"  NELEM(V)        "# of non-null values"  NVALID(V)
-\end{verbatim}
-    where V represents the name of a vector column or a manually
-    constructed vector using curly brackets as described below.  The
-    first 6 of these functions ignore any null values in the vector when
-    computing the result.  The STDDEV() function computes the sample
-    standard deviation, i.e. it is proportional to 1/SQRT(N-1) instead
-    of 1/SQRT(N), where N is NVALID(V).
-
-    The SUM function literally sums all  the elements in x,  returning a
-    scalar value.   If V  is  a  boolean  vector, SUM returns the number
-    of TRUE elements. The NELEM function  returns the number of elements
-    in vector V whereas NVALID return the number of non-null elements in
-    the  vector.   (NELEM  also  operates  on  bit  and string  columns,
-    returning their column widths.)  As an example, to  test whether all
-    elements of two vectors satisfy a  given logical comparison, one can
-    use the expression
-
-\begin{verbatim}
-              SUM( COL1 > COL2 ) == NELEM( COL1 )
-\end{verbatim}
-
-    which will return TRUE if all elements  of  COL1  are  greater  than
-    their corresponding elements in COL2.
-
-    To  specify  a  single  element  of  a  vector, give the column name
-    followed by  a  comma-separated  list  of  coordinates  enclosed  in
-    square  brackets.  For example, if a vector column named PHAS exists
-    in the table as a one dimensional, 256  component  list  of  numbers
-    from  which  you  wanted to select the 57th component for use in the
-    expression, then PHAS[57] would do the  trick.   Higher  dimensional
-    arrays  of  data  may appear in a column.  But in order to interpret
-    them, the TDIMn keyword must appear in the header.  Assuming that  a
-    (4,4,4,4)  array  is packed into each row of a column named ARRAY4D,
-    the  (1,2,3,4)  component  element  of  each  row  is  accessed   by
-    ARRAY4D[1,2,3,4].    Arrays   up   to   dimension  5  are  currently
-    supported.  Each vector index can itself be an expression,  although
-    it  must  evaluate  to  an  integer  value  within the bounds of the
-    vector.  Vector columns which contain spaces or arithmetic operators
-    must   have   their   names  enclosed  in  "\$"  characters  as  with
-    \$ARRAY-4D\$[1,2,3,4].
-
-    A  more  C-like  syntax  for  specifying  vector  indices  is   also
-    available.   The element used in the preceding example alternatively
-    could be specified with the syntax  ARRAY4D[4][3][2][1].   Note  the
-    reverse  order  of  indices  (as in C), as well as the fact that the
-    values are still ones-based (as  in  Fortran  --  adopted  to  avoid
-    ambiguity  for  1D vectors).  With this syntax, one does not need to
-    specify all of the indices.  To  extract  a  3D  slice  of  this  4D
-    array, use ARRAY4D[4].
-
-    Variable-length vector columns are not supported.
-
-    Vectors can  be manually constructed  within the expression  using a
-    comma-separated list of  elements surrounded by curly braces ('\{\}').
-    For example, '\{1,3,6,1\}' is a 4-element vector containing the values
-    1, 3, 6, and 1.  The  vector can contain  only boolean, integer, and
-    real values (or expressions).  The elements will  be promoted to the
-    highest  data type   present.  Any   elements   which  are themselves
-    vectors, will be expanded out with  each of its elements becoming an
-    element in the constructed vector.
-
-
-\subsection{Good Time Interval Filtering}
-
-    A common filtering method involves selecting rows which have a time
-    value which lies within what is called a Good Time Interval or GTI.
-    The time intervals are defined in a separate FITS table extension
-    which contains 2 columns giving the start and stop time of each
-    good interval.  The filtering operation accepts only those rows of
-    the input table which have an associated time which falls within
-    one of the time intervals defined in the GTI extension. A high
-    level function, gtifilter(a,b,c,d), is available which evaluates
-    each row of the input table  and returns TRUE  or FALSE depending
-    whether the row is inside or outside the  good time interval.  The
-    syntax is
-
-\begin{verbatim}
-      gtifilter( [ "gtifile" [, expr [, "STARTCOL", "STOPCOL" ] ] ] )
-    or
-      gtifilter( [ 'gtifile' [, expr [, 'STARTCOL', 'STOPCOL' ] ] ] )
-\end{verbatim}
-    where  each "[]" demarks optional parameters.  Note that  the quotes
-    around the gtifile and START/STOP column are required.  Either single
-    or double quotes may be used.  In cases where this expression is
-    entered on the Unix command line, enclose the entire expression in
-    double quotes, and then use single quotes within the expression to
-    enclose the 'gtifile' and other terms.  It is also usually possible
-    to do the reverse, and enclose the whole expression in single quotes
-    and then use double quotes within the expression.  The gtifile,
-    if specified,  can be blank  ("") which will  mean to use  the first
-    extension  with   the name "*GTI*"  in   the current  file,  a plain
-    extension  specifier (eg, "+2",  "[2]", or "[STDGTI]") which will be
-    used  to  select  an extension  in  the current  file, or  a regular
-    filename with or without an extension  specifier which in the latter
-    case  will mean to  use the first  extension  with an extension name
-    "*GTI*".  Expr can be   any arithmetic expression, including  simply
-    the time  column  name.  A  vector  time expression  will  produce a
-    vector boolean  result.  STARTCOL and  STOPCOL are the  names of the
-    START/STOP   columns in the    GTI extension.  If   one  of them  is
-    specified, they both  must be.
-
-    In  its  simplest form, no parameters need to be provided -- default
-    values will be used.  The expression "gtifilter()" is equivalent to
-
-\begin{verbatim}
-       gtifilter( "", TIME, "*START*", "*STOP*" )
-\end{verbatim}
-    This will search the current file for a GTI  extension,  filter  the
-    TIME  column in the current table, using START/STOP times taken from
-    columns in the GTI  extension  with  names  containing  the  strings
-    "START"  and "STOP".  The wildcards ('*') allow slight variations in
-    naming conventions  such  as  "TSTART"  or  "STARTTIME".   The  same
-    default  values  apply for unspecified parameters when the first one
-    or  two  parameters  are  specified.   The  function   automatically
-    searches   for   TIMEZERO/I/F   keywords  in  the  current  and  GTI
-    extensions, applying a relative time offset, if necessary.
-
-
-\subsection{Spatial Region Filtering}
-
-    Another common  filtering method selects rows based on whether the
-    spatial position associated with each row is located within a given
-    2-dimensional region.  The syntax for this high-level filter is
-
-\begin{verbatim}
-       regfilter( "regfilename" [ , Xexpr, Yexpr [ , "wcs cols" ] ] )
-\end{verbatim}
-    where each "[]" demarks optional parameters. The region file name
-    is required and must be  enclosed in quotes.  The remaining
-    parameters are optional.  There are 2 supported formats for the
-    region file: ASCII file or FITS binary table.  The region file
-    contains a list of one or more geometric shapes (circle,
-    ellipse, box, etc.) which defines a region on the celestial sphere
-    or an area within a particular 2D image.  The region file is
-    typically generated using an image display program such as fv/POW
-    (distribute by the HEASARC), or ds9 (distributed by the Smithsonian
-    Astrophysical Observatory).  Users should refer to the documentation
-    provided with these programs for more details on the syntax used in
-    the region files.  The FITS region file format is defined in a document
-    available from the FITS Support Office at
-    http://fits.gsfc.nasa.gov/ registry/ region.html
-
-    In its simplest form, (e.g., regfilter("region.reg") ) the
-    coordinates in the default 'X' and 'Y' columns will be used to
-    determine if each row is inside or outside the area specified in
-    the region file.  Alternate position column names, or expressions,
-    may be entered if needed, as in
-
-\begin{verbatim}
-        regfilter("region.reg", XPOS, YPOS)
-\end{verbatim}
-    Region filtering can be applied most unambiguously if the positions
-    in the region file and in the table to be filtered are both give in
-    terms of absolute celestial coordinate units.  In this case the
-    locations and sizes of the geometric shapes in the region file are
-    specified in angular units on the sky (e.g., positions given in
-    R.A. and Dec.  and sizes in arcseconds or arcminutes).  Similarly,
-    each row of the filtered table will have a celestial coordinate
-    associated with it.  This association is usually implemented using
-    a set of so-called 'World Coordinate System' (or WCS) FITS keywords
-    that define the coordinate transformation that must be applied to
-    the values in the 'X' and 'Y' columns to calculate the coordinate.
-
-    Alternatively, one can perform spatial filtering using unitless
-    'pixel' coordinates for the regions and row positions.  In this
-    case the user must be careful to ensure that the positions in the 2
-    files are self-consistent.  A typical problem is that the region
-    file may be generated using a binned image, but the unbinned
-    coordinates are given in the event table.  The ROSAT events files,
-    for example, have X and Y pixel coordinates that range from 1 -
-    15360.  These coordinates are typically binned by a factor of 32 to
-    produce a 480x480 pixel image.  If one then uses a region file
-    generated from this image (in image pixel units) to filter the
-    ROSAT events file, then the X and Y column values must be converted
-    to corresponding pixel units as in:
-
-\begin{verbatim}
-        regfilter("rosat.reg", X/32.+.5, Y/32.+.5)
-\end{verbatim}
-    Note that this binning conversion is not necessary if the region
-    file is specified using celestial coordinate units instead of pixel
-    units because CFITSIO is then able to directly compare the
-    celestial coordinate of each row in the table with the celestial
-    coordinates in the region file without having to know anything
-    about how the image may have been binned.
-
-    The last "wcs cols" parameter should rarely be needed. If supplied,
-    this  string contains the names of the 2 columns (space or comma
-    separated) which have the associated WCS keywords. If not supplied,
-    the filter  will scan the X  and Y expressions for column names.
-    If only one is found in each  expression, those columns will be
-    used, otherwise an error will be returned.
-
-    These region shapes are supported (names are case insensitive):
-
-\begin{verbatim}
-       Point         ( X1, Y1 )               <- One pixel square region
-       Line          ( X1, Y1, X2, Y2 )       <- One pixel wide region
-       Polygon       ( X1, Y1, X2, Y2, ... )  <- Rest are interiors with

-\end{verbatim}
-    where (Xc,Yc) is  the coordinate of  the shape's center; (X\#,Y\#) are
-    the coordinates  of the shape's edges;  Rxxx are the shapes' various
-    Radii or semimajor/minor  axes; and Axxx  are the angles of rotation
-    (or bounding angles for Sector) in degrees.  For rotated shapes, the
-    rotation angle  can  be left  off, indicating  no rotation.   Common
-    alternate  names for the regions  can also be  used: rotbox = box;
-    rotrectangle = rectangle;  (rot)rhombus = (rot)diamond;  and pie
-    = sector.  When a  shape's name is  preceded by a minus sign, '-',
-    the defined region  is instead the area  *outside* its boundary (ie,
-    the region is inverted).  All the shapes within a single region
-    file are OR'd together to create the region, and the order is
-    significant. The overall way of looking at region files is that if
-    the first region is an excluded region then a dummy included region
-    of the whole detector is inserted in the front. Then each region
-    specification as it is processed overrides any selections inside of
-    that region specified by previous regions. Another way of thinking
-    about this is that if a previous excluded region is completely
-    inside of a subsequent included region the excluded region is
-    ignored.
-
-    The positional coordinates may be given either in pixel units,
-    decimal degrees or hh:mm:ss.s, dd:mm:ss.s units.  The shape sizes
-    may be given in pixels, degrees, arcminutes, or arcseconds.  Look
-    at examples of region file produced by fv/POW or ds9 for further
-    details of the region file format.
-
-    There are three low-level  functions that are primarily for use with
-    regfilter function, but they  can  be  called  directly.  They
-    return  a  boolean true   or  false  depending   on  whether a   two
-    dimensional point is in the region or not.  The positional coordinates
-    must be given in pixel units:
-
-\begin{verbatim}
-    "point in a circular region"
-          circle(xcntr,ycntr,radius,Xcolumn,Ycolumn)
-
-    "point in an elliptical region"
-         ellipse(xcntr,ycntr,xhlf_wdth,yhlf_wdth,rotation,Xcolumn,Ycolumn)
-
-    "point in a rectangular region"
-             box(xcntr,ycntr,xfll_wdth,yfll_wdth,rotation,Xcolumn,Ycolumn)
-
-    where
-       (xcntr,ycntr) are the (x,y) position of the center of the region
-       (xhlf_wdth,yhlf_wdth) are the (x,y) half widths of the region
-       (xfll_wdth,yfll_wdth) are the (x,y) full widths of the region
-       (radius) is half the diameter of the circle
-       (rotation) is the angle(degrees) that the region is rotated with
-             respect to (xcntr,ycntr)
-       (Xcoord,Ycoord) are the (x,y) coordinates to test, usually column
-             names
-       NOTE: each parameter can itself be an expression, not merely a
-             column name or constant.

-\section{ Binning or Histogramming Specification}
-
-The optional binning specifier is enclosed in square brackets and can
-be distinguished from a general row filter specification by the fact
-that it begins with the keyword 'bin'  not immediately followed by an
-equals sign.  When binning is specified, a temporary N-dimensional FITS
-primary array is created by computing the histogram of the values in
-the specified columns of a FITS table extension.  After the histogram
-is computed the input FITS file containing the table is then closed and
-the temporary FITS primary array is opened and passed to the
-application program.  Thus, the application program never sees the
-original FITS table and only sees the image in the new temporary file
-(which has no additional extensions).  Obviously, the application
-program must be expecting to open a FITS image and not a FITS table in
-this case.
-
-The data type of the FITS histogram image may be specified by appending
-'b' (for 8-bit byte), 'i' (for 16-bit integers), 'j' (for 32-bit
-integer), 'r' (for 32-bit floating points), or 'd' (for 64-bit double
-precision floating point)  to the 'bin' keyword (e.g. '[binr X]'
-creates a real floating point image).  If the data type is not
-explicitly specified then a 32-bit integer image will be created by
-default, unless the weighting option is also specified in which case
-the image will have a 32-bit floating point data type by default.
-
-The histogram image may have from 1 to 4 dimensions (axes), depending
-on the number of columns that are specified.  The general form of the
-binning specification is:
-
-\begin{verbatim}
- [bin{bijrd}  Xcol=min:max:binsize, Ycol= ..., Zcol=..., Tcol=...; weight]
-\end{verbatim}
-in which up to 4 columns, each corresponding to an axis of the image,
-are listed. The column names are case insensitive, and the column
-number may be given instead of the name, preceded by a pound sign
-(e.g., [bin \#4=1:512]).  If the column name is not specified, then
-CFITSIO will first try to use the 'preferred column' as specified by
-the CPREF keyword if it exists (e.g., 'CPREF = 'DETX,DETY'), otherwise
-column names 'X', 'Y', 'Z', and 'T' will be assumed for each of the 4
-axes, respectively.  In cases where the column name could be confused
-with an arithmetic expression, enclose the column name in parentheses to
-force the name to be interpreted literally.
-
-Each column name may be followed by an equals sign and then the lower
-and upper range of the histogram, and the size of the histogram bins,
-separated by colons.  Spaces are allowed before and after the equals
-sign but not within the 'min:max:binsize' string.  The min, max and
-binsize values may be integer or floating point numbers, or they may be
-the names of keywords in the header of the table.  If the latter, then
-the value of that keyword is substituted into the expression.
-
-Default values for the min, max and binsize quantities will be
-used if not explicitly given in the binning expression as shown
-in these examples:
-
-\begin{verbatim}
-    [bin x = :512:2]  - use default minimum value
-    [bin x = 1::2]    - use default maximum value
-    [bin x = 1:512]   - use default bin size
-    [bin x = 1:]      - use default maximum value and bin size
-    [bin x = :512]    - use default minimum value and bin size
-    [bin x = 2]       - use default minimum and maximum values
-    [bin x]           - use default minimum, maximum and bin size
-    [bin 4]           - default 2-D image, bin size = 4 in both axes
-    [bin]             - default 2-D image
-\end{verbatim}
-CFITSIO  will use the value of the TLMINn, TLMAXn, and TDBINn keywords,
-if they exist, for the default min, max, and binsize, respectively.  If
-they do not exist then CFITSIO will use the actual minimum and maximum
-values in the column for the histogram min and max values.  The default
-binsize will be set to 1, or (max - min) / 10., whichever is smaller,
-so that the histogram will have at least 10 bins along each axis.
-
-A shortcut notation is allowed if all the columns/axes have the same
-binning specification.  In this case all the column names may be listed
-within parentheses, followed by the (single) binning specification, as
-in:
-
-\begin{verbatim}
-    [bin (X,Y)=1:512:2]
-    [bin (X,Y) = 5]
-\end{verbatim}
-
-The optional weighting factor is the last item in the binning specifier
-and, if present, is separated from the list of columns by a
-semi-colon.  As the histogram is accumulated, this weight is used to
-incremented the value of the appropriated bin in the histogram.  If the
-weighting factor is not specified, then the default weight = 1 is
-assumed.  The weighting factor may be a constant integer or floating
-point number, or the name of a keyword containing the weighting value.
-Or the weighting factor may be the name of a table column in which case
-the value in that column, on a row by row basis, will be used.
-
-In some cases, the column or keyword may give the reciprocal of the
-actual weight value that is needed.  In this case, precede the weight
-keyword or column name by a slash '/' to tell CFITSIO to use the
-reciprocal of the value when constructing the histogram.
-
-For  complex or commonly  used  histograms, one  can also  place its
-description  into  a  text  file and  import   it  into  the binning
-specification  using the  syntax [bin  @filename.txt].  The file's
-contents  can extend over   multiple lines, although  it must still
-conform to the  no-spaces rule  for the min:max:binsize syntax and each
-axis specification must still be comma-separated.  Any lines in the
-external text file that begin with 2 slash characters ('//') will be
-ignored and may be used to add comments into the file.
-
- Examples:
-
-
-\begin{verbatim}
-    [bini detx, dety]                - 2-D, 16-bit integer histogram
-                                       of DETX and DETY columns, using
-                                       default values for the histogram
-                                       range and binsize
-
-    [bin (detx, dety)=16; /exposure] - 2-D, 32-bit real histogram of DETX
-                                       and DETY columns with a bin size = 16
-                                       in both axes. The histogram values
-                                       are divided by the EXPOSURE keyword
-                                       value.
-
-    [bin time=TSTART:TSTOP:0.1]      - 1-D lightcurve, range determined by

-                                       and 1000 bins in the range
-                                       8000. to 8100. for the Y axis.
-

-\end{verbatim}
-\chapter{Template Files }
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described in the following sections.
-
-
-\section{Detailed Template Line Format}
-
-The format of each ASCII template line closely follows the format of a
-FITS keyword record:
-
-\begin{verbatim}
-  KEYWORD = KEYVALUE / COMMENT
-\end{verbatim}
-except that free format may be used (e.g., the equals sign may appear
-at any position in the line) and TAB characters are allowed and are
-treated the same as space characters.  The KEYVALUE and COMMENT fields
-are optional.  The equals sign character is also optional, but it is
-recommended that it be included for clarity.  Any template line that
-begins with the pound '\#' character is ignored by the template parser
-and may be use to insert comments into the template file itself.
-
-The KEYWORD name field is limited to 8 characters in length and only
-the letters A-Z, digits 0-9, and the hyphen and underscore characters
-may be used, without any embedded spaces. Lowercase letters in the
-template keyword name will be converted to uppercase.  Leading spaces
-in the template line preceding the keyword name are generally ignored,
-except if the first 8 characters of a template line are all blank, then
-the entire line is treated as a FITS comment keyword (with a blank
-keyword name) and is copied verbatim into the FITS header.
-
-The KEYVALUE field may have any allowed  FITS  data type: character
-string, logical, integer, real, complex integer, or complex real.  The
-character string values need not be enclosed in single quote characters
-unless they are necessary to distinguish the string from a different
-data type (e.g.  2.0 is a real but '2.0' is a string).  The keyword has
-an undefined (null) value if the template record only contains blanks
-following the "=" or between the "=" and the "/" comment field
-delimiter.
-
-String keyword values longer than 68 characters (the maximum length
-that will fit in a single FITS keyword record) are permitted using the
-CFITSIO long string convention. They can either be specified as a
-single long line in the template, or by using multiple lines where the
-continuing lines contain the 'CONTINUE' keyword, as in this example:
-
-\begin{verbatim}
-  LONGKEY = 'This is a long string value that is contin&'
-  CONTINUE  'ued over 2 records' / comment field goes here
-\end{verbatim}
-The format of template lines with CONTINUE keyword is very strict:  3
-spaces must follow CONTINUE and the rest of the line is copied verbatim
-to the FITS file.
-
-The start of the optional COMMENT field must be preceded by "/", which
-is used to separate it from the keyword value field. Exceptions are if
-the KEYWORD name field contains COMMENT, HISTORY, CONTINUE, or if the
-first 8 characters of the template line are blanks.
-
-More than one Header-Data Unit (HDU) may be defined in the template
-file.  The start of an HDU definition is denoted with a SIMPLE or
-XTENSION template line:
-
-1) SIMPLE begins a Primary HDU definition. SIMPLE may only appear as
-the  first keyword in the template file. If the template file begins
-with XTENSION instead of SIMPLE, then a default empty Primary HDU is
-created, and the template is then assumed to define the keywords
-starting with the first extension following the Primary HDU.
-
-2) XTENSION marks the beginning of a new extension HDU definition.  The
-previous HDU will be closed at this point and processing of the next
-extension begins.
-
-
-\section{Auto-indexing of Keywords}
-
-If a template keyword name ends with a "\#" character, it is said to be
-'auto-indexed'.   Each "\#" character will be replaced by the current
-integer index value, which gets reset = 1 at the start of each new HDU
-in the file (or 7 in the special case of a GROUP definition).  The
-FIRST indexed keyword in each template HDU definition is used as the
-'incrementor';  each subsequent occurrence of this SAME keyword will
-cause the index value to be incremented.  This behavior can be rather
-subtle, as illustrated in the following examples in which the TTYPE
-keyword is the incrementor in both cases:
-
-\begin{verbatim}
-  TTYPE# = TIME
-  TFORM# = 1D
-  TTYPE# = RATE
-  TFORM# = 1E
-\end{verbatim}
-will create TTYPE1, TFORM1, TTYPE2, and TFORM2 keywords.  But if the
-template looks like,
-
-\begin{verbatim}
-  TTYPE# = TIME
-  TTYPE# = RATE
-  TFORM# = 1D
-  TFORM# = 1E
-\end{verbatim}
-this results in a FITS files with  TTYPE1, TTYPE2, TFORM2, and TFORM2,
-which is probably not what was intended!
-
-
-\section{Template Parser Directives}
-
-In addition to the template lines which define individual keywords, the
-template parser recognizes 3 special directives which are each preceded
-by the backslash character:  \verb+ \include, \group+, and \verb+ \end+.
-
-The 'include' directive must be followed by a filename. It forces the
-parser to temporarily stop reading the current template file and begin
-reading the include file. Once the parser reaches the end of the
-include file it continues parsing the current template file.  Include
-files can be nested, and HDU definitions can span multiple template
-files.
-
-The start of a GROUP definition is denoted with the 'group' directive,
-and the end of a GROUP definition is denoted with the 'end' directive.
-Each GROUP contains 0 or more member blocks (HDUs or GROUPs). Member
-blocks of type GROUP can contain their own member blocks. The GROUP
-definition itself occupies one FITS file HDU of special type (GROUP
-HDU), so if a template specifies 1 group with 1 member HDU like:
-
-\begin{verbatim}
-\group
-grpdescr = 'demo'
-xtension bintable
-# this bintable has 0 cols, 0 rows
-\end
-\end{verbatim}
-then the parser creates a FITS file with 3 HDUs :
-
-\begin{verbatim}
-1) dummy PHDU
-2) GROUP HDU (has 1 member, which is bintable in HDU number 3)
-3) bintable (member of GROUP in HDU number 2)
-\end{verbatim}
-Technically speaking, the GROUP HDU is a BINTABLE with 6 columns. Applications
-can define additional columns in a GROUP HDU using TFORMn and TTYPEn
-(where n is 7, 8, ....) keywords or their auto-indexing equivalents.
-
-For a more complicated example of a template file using the group directives,
-look at the sample.tpl file that is included in the CFITSIO distribution.
-
-
-\section{Formal Template Syntax}
-
-The template syntax can formally be defined as follows:
-
-\begin{verbatim}
-    TEMPLATE = BLOCK [ BLOCK ... ]
-
-       BLOCK = { HDU | GROUP }
-
-       GROUP = \GROUP [ BLOCK ... ] \END
-
-         HDU = XTENSION [ LINE ... ] { XTENSION | \GROUP | \END | EOF }
-
-        LINE = [ KEYWORD [ = ] ] [ VALUE ] [ / COMMENT ]
-
-    X ...     - X can be present 1 or more times
-    { X | Y } - X or Y
-    [ X ]     - X is optional
-\end{verbatim}
-
-At the topmost level, the template defines 1 or more template blocks. Blocks
-can be either HDU (Header Data Unit) or a GROUP. For each block the parser
-creates 1 (or more for GROUPs) FITS file HDUs.
-
-
-
-\section{Errors}
-
-In general the fits\_execute\_template() function tries to be as atomic
-as possible, so either everything is done or nothing is done. If an
-error occurs during parsing of the template, fits\_execute\_template()
-will (try to) delete the top level BLOCK (with all its children if any)
-in which the error occurred, then it will stop reading the template file
-and it will return with an error.
-
-
-\section{Examples}
-
-1. This template file will create a 200 x 300 pixel image, with 4-byte
-integer pixel values, in the primary HDU:
-
-\begin{verbatim}
-  SIMPLE = T
-  BITPIX = 32
-  NAXIS = 2     / number of dimensions
-  NAXIS1 = 100  / length of first axis
-  NAXIS2 = 200  / length of second axis
-  OBJECT = NGC 253 / name of observed object
-\end{verbatim}
-The allowed values of BITPIX are 8, 16, 32, -32, or -64,
-representing, respectively, 8-bit integer, 16-bit integer, 32-bit
-integer, 32-bit floating point, or 64 bit floating point pixels.
-
-2.  To create a FITS  table, the template first needs to include
-XTENSION = TABLE or BINTABLE to define whether it is an ASCII or binary
-table, and NAXIS2 to define the number of rows in the table.  Two
-template lines are then needed to define the name (TTYPEn) and FITS data
-format (TFORMn) of the columns, as in this example:
-
-\begin{verbatim}
-  xtension = bintable
-  naxis2 = 40
-  ttype# = Name
-  tform# = 10a
-  ttype# = Npoints
-  tform# = j
-  ttype# = Rate
-  tunit# = counts/s
-  tform# = e
-\end{verbatim}
-The above example defines a null primary array followed by a 40-row
-binary table extension with 3 columns called 'Name', 'Npoints', and
-'Rate', with data formats of '10A' (ASCII character string), '1J'
-(integer) and '1E' (floating point), respectively.  Note that the other
-required FITS keywords (BITPIX, NAXIS, NAXIS1, PCOUNT, GCOUNT, TFIELDS,
-and END) do not need to be explicitly defined in the template because
-their values can be inferred from the other keywords in the template.
-This example also illustrates that the templates are generally
-case-insensitive (the keyword names and TFORMn values are converted to
-upper-case in the FITS file) and that string keyword values generally
-do not need to be enclosed in quotes.
-
-\chapter{  Local FITS Conventions }
-
-CFITSIO supports several local FITS conventions which are not
-defined in the official NOST FITS standard and which are not
-necessarily recognized or supported by other FITS software packages.
-Programmers should be cautious about using these features, especially
-if the FITS files that are produced are expected to be processed by
-other software systems which do not use the CFITSIO interface.
-
-
-\section{64-Bit Long Integers}
-
-CFITSIO supports reading and writing FITS images or table columns containing
-64-bit integer data values. Support for 64-bit integers was added to the
-official FITS Standard in December 2005.
- FITS 64-bit images have BITPIX =
-64, and the 64-bit binary table columns have TFORMn = 'K'.  CFITSIO also
-supports the 'Q' variable-length array table column format which is
-analogous to the 'P' column format except that the array descriptor
-is stored as a pair of 64-bit integers.
-
-For the convenience of C programmers, the fitsio.h include file
-defines (with a typedef statement) the 'LONGLONG' datatype to be
-equivalent to an appropriate 64-bit integer datatype on each platform.
-Since there is currently no universal standard
-for the name of the 64-bit integer datatype (it might be defined as
-'long long', 'long', or '\_\_int64' depending on the platform)
-C programmers may prefer to use the 'LONGLONG' datatype when
-declaring or allocating 64-bit integer quantities when writing
-code which needs to run on multiple platforms.
-Note that CFITSIO will implicitly convert the datatype when reading
-or writing FITS 64-bit integer images and columns with data arrays of
-a different integer or floating point datatype, but there is an
-increased risk of loss of numerical precision or
-numerical overflow  in this case.
-
-
-\section{Long String Keyword Values.}
-
-The length of a standard FITS string keyword is limited to 68
-characters because it must fit entirely within a single FITS header
-keyword record.  In some instances it is necessary to encode strings
-longer than this limit, so CFITSIO supports a local convention in which
-the string value is continued over multiple keywords.  This
-continuation convention uses an ampersand character at the end of each
-substring to indicate that it is continued on the next keyword, and the
-continuation keywords all have the name CONTINUE without an equal sign
-in column 9. The string value may be continued in this way over as many
-additional CONTINUE keywords as is required.  The following lines
-illustrate this continuation convention which is used in the value of
-the STRKEY keyword:
-
-\begin{verbatim}
-LONGSTRN= 'OGIP 1.0'    / The OGIP Long String Convention may be used.
-STRKEY  = 'This is a very long string keyword&'  / Optional Comment
-CONTINUE  ' value that is continued over 3 keywords in the &  '
-CONTINUE  'FITS header.' / This is another optional comment.
-\end{verbatim}
-It is recommended that the LONGSTRN keyword, as shown here, always be
-included in any HDU that uses this longstring convention as a warning
-to any software that must read the keywords.  A routine called fits\_write\_key\_longwarn
-has been provided in CFITSIO to write this keyword if it does not
-already exist.
-
-This long string convention is supported by the following CFITSIO
-routines:
-
-\begin{verbatim}
-    fits_write_key_longstr  - write a long string keyword value
-    fits_insert_key_longstr - insert a long string keyword value
-    fits_modify_key_longstr - modify a long string keyword value
-    fits_update_key_longstr - modify a long string keyword value
-    fits_read_key_longstr   - read  a long string keyword value
-    fits_delete_key         - delete a keyword
-\end{verbatim}
-The fits\_read\_key\_longstr routine is unique among all the CFITSIO
-routines in that it internally allocates memory for the long string
-value;  all the other CFITSIO routines that deal with arrays require
-that the calling program pre-allocate adequate space to hold the array
-of data.  Consequently, programs which use the fits\_read\_key\_longstr
-routine must be careful to free the allocated memory for the string
-when it is no longer needed.
-
-The following 2 routines also have limited support for this long string
-convention,
-
-\begin{verbatim}
-      fits_modify_key_str - modify an existing string keyword value
-      fits_update_key_str - update a string keyword value
-\end{verbatim}
-in that they will correctly overwrite an existing long string value,
-but the new string value is limited to a maximum of 68 characters in
-length.
-
-The more commonly used CFITSIO routines to write string valued keywords
-(fits\_update\_key and fits\_write\_key) do not support this long
-string convention and only support strings up to 68 characters in
-length.  This has been done deliberately to prevent programs from
-inadvertently writing keywords using this non-standard convention
-without the explicit intent of the programmer or user.   The
-fits\_write\_key\_longstr routine must be called instead to write long
-strings.  This routine can also be used to write ordinary string values
-less than 68 characters in length.
-
-
-\section{Arrays of Fixed-Length Strings in Binary Tables}
-
-CFITSIO supports 2 ways to specify that a character column in a binary
-table contains an array of fixed-length strings.  The first way, which
-is officially supported by the FITS Standard document, uses the TDIMn keyword.
-For example, if TFORMn = '60A' and TDIMn = '(12,5)' then that
-column will be interpreted as containing an array of 5 strings, each 12
-characters long.
-
-CFITSIO also supports a
-local convention for the format of the TFORMn keyword value of the form
-'rAw' where 'r' is an integer specifying the total width in characters
-of the column, and 'w' is an integer specifying the (fixed) length of
-an individual unit string within the vector.  For example, TFORM1 =
-'120A10' would indicate that the binary table column is 120 characters
-wide and consists of 12 10-character length strings.  This convention
-is recognized by the CFITSIO routines that read or write strings in
-binary tables.   The Binary Table definition document specifies that
-other optional characters may follow the data type code in the TFORM
-keyword, so this local convention is in compliance with the
-FITS standard although other FITS readers may not
-recognize this convention.
-
-The Binary Table definition document that was approved by the IAU in
-1994 contains an appendix describing an alternate convention for
-specifying arrays of fixed or variable length strings in a binary table
-character column (with the form 'rA:SSTRw/nnn)'.  This appendix was not
-officially voted on by the IAU and hence is still provisional.  CFITSIO
-does not currently support this proposal.
-
-
-\section{Keyword Units Strings}
-
-One limitation of the current FITS Standard is that it does not define
-a specific convention for recording the physical units of a keyword
-value.  The TUNITn keyword can be used to specify the physical units of
-the values in a table column, but there is no analogous convention for
-keyword values.  The comment field of the keyword is often used for
-this purpose, but the units are usually not specified in a well defined
-format that FITS readers can easily recognize and extract.
-
-To solve this problem, CFITSIO uses a local convention in which the
-keyword units are enclosed in square brackets as the first token in the
-keyword comment field; more specifically, the opening square bracket
-immediately follows the slash '/' comment field delimiter and a single
-space character.  The following examples illustrate keywords that use
-this convention:
-
-
-\begin{verbatim}
-EXPOSURE=               1800.0 / [s] elapsed exposure time
-V_HELIO =                16.23 / [km s**(-1)] heliocentric velocity
-LAMBDA  =                5400. / [angstrom] central wavelength
-FLUX    = 4.9033487787637465E-30 / [J/cm**2/s] average flux
-\end{verbatim}
-
-In general, the units named in the IAU(1988) Style Guide are
-recommended, with the main exception that the preferred unit for angle
-is 'deg' for degrees.
-
-The fits\_read\_key\_unit and fits\_write\_key\_unit routines in
-CFITSIO read and write, respectively, the keyword unit strings in an
-existing keyword.
-
-
-\section{HIERARCH Convention for Extended Keyword Names}
-
-CFITSIO supports the HIERARCH keyword convention which allows keyword
-names that are longer then 8 characters and may contain the full range
-of printable ASCII text characters.  This convention
-was developed at the European Southern Observatory (ESO)  to support
-hierarchical FITS keyword such as:
-
-\begin{verbatim}
-HIERARCH ESO INS FOCU POS = -0.00002500 / Focus position
-\end{verbatim}
-Basically, this convention uses the FITS keyword 'HIERARCH' to indicate
-that this convention is being used, then the actual keyword name
-({\tt'ESO INS FOCU POS'} in this example) begins in column 10 and can
-contain any printable ASCII text characters, including spaces.  The
-equals sign marks the end of the keyword name and is followed by the
-usual value and comment fields just as in standard FITS keywords.
-Further details of this convention are described at
-http://arcdev.hq.eso.org/dicb/dicd/dic-1-1.4.html (search for
-HIERARCH).
-
-This convention allows a much broader range of keyword names
-than is allowed by the FITS Standard.  Here are more examples
-of such keywords:
-
-\begin{verbatim}
-HIERARCH LongKeyword = 47.5 / Keyword has > 8 characters, and mixed case
-HIERARCH XTE$TEMP = 98.6 / Keyword contains the '$' character
-HIERARCH Earth is a star = F / Keyword contains embedded spaces
-\end{verbatim}
-CFITSIO will transparently read and write these keywords, so application
-programs do not in general need to know anything about the specific
-implementation details of the HIERARCH convention.  In particular,
-application programs do not need to specify the `HIERARCH' part of the
-keyword name when reading or writing keywords (although it
-may be included if desired).  When writing a keyword, CFITSIO first
-checks to see if the keyword name is legal as a standard FITS keyword
-(no more than 8 characters long and containing only letters, digits, or
-a minus sign or underscore). If so it writes it as a standard FITS
-keyword, otherwise it uses the hierarch convention to write the
-keyword.   The maximum keyword name length is 67 characters, which
-leaves only 1 space for the value field.  A more practical limit is
-about 40 characters, which leaves enough room for most keyword values.
-CFITSIO returns an error if there is not enough room for both the
-keyword name and the keyword value on the 80-character card, except for
-string-valued keywords which are simply truncated so that the closing
-quote character falls in column 80.  In the current implementation,
-CFITSIO preserves the case of the letters when writing the keyword
-name, but it is case-insensitive when reading or searching for a
-keyword.  The current implementation allows any ASCII text character
-(ASCII 32 to ASCII 126) in the keyword name except for the '='
-character.  A space is also required on either side of the equal sign.
-
-
-\section{Tile-Compressed Image Format}
-
-CFITSIO supports a convention for compressing n-dimensional images and
-storing the resulting byte stream in a variable-length column in a FITS
-binary table.  The general principle used in this convention is to
-first divide the n-dimensional image into a rectangular grid of
-subimages or `tiles'.  Each tile is then compressed as a continuous
-block of data, and the resulting compressed byte stream is stored in a
-row of a variable length column in a FITS binary table. By dividing the
-image into tiles it is generally possible to extract and uncompress
-subsections of the image without having to uncompress the whole image.
-The default tiling pattern treats each row of a 2-dimensional image (or
-higher dimensional cube) as a tile, such that each tile contains NAXIS1
-pixels (except the default with the HCOMPRESS algorithm is to
-compress the whole 2D image as a single tile). Any other rectangular
-tiling pattern may also be defined. In
-the case of relatively small images it may be sufficient to compress
-the entire image as a single tile, resulting in an output binary table
-with 1 row.  In the case of 3-dimensional data cubes, it may be
-advantageous to treat each plane of the cube as a separate tile if
-application software typically needs to access the cube on a plane by
-plane basis.
-
-See section 5.6 ``Image Compression''
-for more information on using this tile-compressed image format.
-
-\chapter{  Optimizing Programs }
-
-CFITSIO has been carefully designed to obtain the highest possible
-speed when reading and writing FITS files.  In order to achieve the
-best performance, however, application programmers must be careful to
-call the CFITSIO routines appropriately and in an efficient sequence;
-inappropriate usage of CFITSIO routines can greatly slow down the
-execution speed of a program.
-
-The maximum possible I/O speed of CFITSIO depends of course on the type
-of computer system that it is running on.  As a rough guide, the
-current generation of workstations can achieve speeds of 2 -- 10 MB/s
-when reading or writing FITS images and similar, or slightly slower
-speeds with FITS binary tables.  Reading of FITS files can occur at
-even higher rates (30MB/s or more) if the FITS file is still cached in
-system memory following a previous read or write operation on the same
-file.  To more accurately predict the best performance that is possible
-on any particular system, a diagnostic program called ``speed.c'' is
-included with the CFITSIO distribution which can be run to
-approximately measure the maximum possible speed of writing and reading
-a test FITS file.
-
-The following 2 sections provide some background on how CFITSIO
-internally manages the data I/O and describes some strategies that may
-be used to optimize the processing speed of software that uses
-CFITSIO.
-
-
-\section{How CFITSIO Manages Data I/O}
-
-Many CFITSIO operations involve transferring only a small number of
-bytes to or from the FITS file (e.g, reading a keyword, or writing a
-row in a table); it would be very inefficient to physically read or
-write such small blocks of data directly in the FITS file on disk,
-therefore CFITSIO maintains a set of internal Input--Output (IO)
-buffers in RAM memory that each contain one FITS block (2880 bytes) of
-data.  Whenever CFITSIO needs to access data in the FITS file, it first
-transfers the FITS block containing those bytes into one of the IO
-buffers in memory.  The next time CFITSIO needs to access bytes in the
-same block it can then go to the fast IO buffer rather than using a
-much slower system disk access routine.  The number of available IO
-buffers is determined by the NIOBUF parameter (in fitsio2.h) and is
-currently set to 40 by default.
-
-Whenever CFITSIO reads or writes data it first checks to see if that
-block of the FITS file is already loaded into one of the IO buffers.
-If not, and if there is an empty IO buffer available, then it will load
-that block into the IO buffer (when reading a FITS file) or will
-initialize a new block (when writing to a FITS file).  If all the IO
-buffers are already full, it must decide which one to reuse (generally
-the one that has been accessed least recently), and flush the contents
-back to disk if it has been modified before loading the new block.
-
-The one major exception to the above process occurs whenever a large
-contiguous set of bytes are accessed, as might occur when reading or
-writing a FITS image.  In this case CFITSIO bypasses the internal IO
-buffers and simply reads or writes the desired bytes directly in the
-disk file with a single call to a low-level file read or write
-routine.  The minimum threshold for the number of bytes to read or
-write this way is set by the MINDIRECT parameter and is currently set
-to 3 FITS blocks = 8640 bytes.  This is the most efficient way to read
-or write large chunks of data and can achieve IO transfer rates of
-5 -- 10MB/s or greater.  Note that this fast direct IO process is not
-applicable when accessing columns of data in a FITS table because the
-bytes are generally not contiguous since they are interleaved by the
-other columns of data in the table.  This explains why the speed for
-accessing FITS tables is generally slower than accessing
-FITS images.
-
-Given this background information, the general strategy for efficiently
-accessing FITS files should be apparent:  when dealing with FITS
-images, read or write large chunks of data at a time so that the direct
-IO mechanism will be invoked;  when accessing FITS headers or FITS
-tables, on the other hand, once a particular FITS block has been
-loading into one of the IO buffers, try to access all the needed
-information in that block before it gets flushed out of the IO buffer.
-It is important to avoid the situation where the same FITS block is
-being read then flushed from a IO buffer multiple times.
-
-The following section gives more specific suggestions for optimizing
-the use of CFITSIO.
-
-
-\section{Optimization Strategies}
-
-1.  Because the data in FITS files is always stored in "big-endian" byte order,
-where the first byte of numeric values contains the most significant bits and the
-last byte contains the least significant bits, CFITSIO must swap the order of the bytes
-when reading or writing FITS files when running on little-endian machines (e.g.,
-Linux and Microsoft Windows operating systems running on PCs with x86 CPUs).
-
-On fairly new CPUs that support "SSSE3" machine instructions
-(e.g., starting with Intel Core 2 CPUs in 2007, and in AMD CPUs
-beginning in 2011) significantly faster 4-byte and 8-byte swapping
-algorithms are available. These faster byte swapping functions are
-not used by default in CFITSIO (because of the potential code
-portablility issues), but users can enable them on supported
-platforms by adding the appropriate compiler flags (-mssse3 with gcc
-or icc on linux) when compiling the swapproc.c source file, which will
-allow the compiler to generate code using the SSSE3 instruction set.
-A convenient way to do this is to configure the CFITSIO library
-with the following command:
-
-\begin{verbatim}
-  >  ./configure --enable-ssse3
-\end{verbatim}
-Note, however, that a binary executable file that is
-created using these faster functions will only run on
-machines that support the SSSE3 machine instructions. It will
-crash on machines that do not support them.
-
-For faster 2-byte swaps on virtually all x86-64 CPUs (even those that
-do not support SSSE3), a variant using only SSE2 instructions exists.
-SSE2 is enabled by default on x86\_64 CPUs with 64-bit operating systems
-(and is also automatically enabled by the --enable-ssse3 flag).
-When running on x86\_64 CPUs with 32-bit operating systems, these faster
-2-byte swapping algorithms are not used by default in CFITSIO, but can be
-enabled explicitly with:
-
-\begin{verbatim}
-./configure --enable-sse2
-\end{verbatim}
-Preliminary testing indicates that these SSSE3 and SSE2 based
-byte-swapping algorithms can boost the CFITSIO performance when
-reading or writing FITS images by 20\% - 30\% or more.
-It is important to note, however, that compiler optimization must be
-turned on (e.g., by using the -O1 or -O2 flags in gcc) when building
-programs that use these fast byte-swapping algorithms in order
-to reap the full benefit of the SSSE3 and SSE2 instructions; without
-optimization, the code may actually run slower than when using
-more traditional byte-swapping techniques.
-
-2.  When dealing with a FITS primary array or IMAGE extension, it is
-more efficient to read or write large chunks of the  image at a time
-(at least 3 FITS blocks = 8640 bytes) so that the direct IO mechanism
-will be used as described in the previous section.  Smaller chunks of
-data are read or written via the IO buffers, which is somewhat less
-efficient because of the extra copy operation and additional
-bookkeeping steps that are required.  In principle it is more efficient
-to read or write as big an array of image pixels at one time as
-possible, however, if the array becomes so large that the operating
-system cannot store it all in RAM, then the performance may be degraded
-because of the increased swapping of virtual memory to disk.
-
-3.  When dealing with FITS tables, the most important efficiency factor
-in the software design is to read or write the data in the FITS file in
-a single pass through the file.  An example of poor program design
-would be to read a large, 3-column table by sequentially reading the
-entire first column, then going back to read the 2nd column, and
-finally the 3rd column; this obviously requires 3 passes through the
-file which could triple the execution time of an IO limited program.
-For small tables this is not important, but when reading multi-megabyte
-sized tables these inefficiencies can become significant.  The more
-efficient procedure in this case is to read or write only as many rows
-of the table as will fit into the available internal IO buffers, then
-access all the necessary columns of data within that range of rows.
-Then after the program is completely finished with the data in those
-rows it can move on to the next range of rows that will fit in the
-buffers, continuing in this way until the entire file has been
-processed.  By using this procedure of accessing all the columns of a
-table in parallel rather than sequentially, each block of the FITS file
-will only be read or written once.
-
-The optimal number of rows to read or write at one time in a given
-table depends on the width of the table row and on the number of IO
-buffers that have been allocated in CFITSIO.  The CFITSIO Iterator routine
-will automatically use the optimal-sized buffer, but there is also a
-CFITSIO routine that will return the optimal number of rows for a given
-table:  fits\_get\_rowsize.  It is not critical to use exactly the
-value of nrows returned by this routine, as long as one does not exceed
-it.  Using a very small value however can also lead to poor performance
-because of the overhead from the larger number of subroutine calls.
-
-The optimal number of rows returned by fits\_get\_rowsize is valid only
-as long as the application program is only reading or writing data in
-the specified table.  Any other calls to access data in the table
-header would  cause additional blocks of data
-to be loaded into the IO buffers displacing data from the original
-table, and should be avoided during the critical period while the table
-is being read or written.
-
-4.  Use the CFITSIO Iterator routine.  This routine provides a
-more `object oriented' way of reading and writing FITS files
-which automatically uses the most appropriate data buffer size
-to achieve the maximum I/O throughput.
-
-5.  Use binary table extensions rather than ASCII table
-extensions for better efficiency  when dealing with tabular data.  The
-I/O to ASCII tables is slower because of the overhead in formatting or
-parsing the ASCII data fields and because ASCII tables are about twice
-as large as binary tables that have the same information content.
-
-6. Design software so that it reads the FITS header keywords in the
-same order in which they occur in the file.  When reading keywords,
-CFITSIO searches forward starting from the position of the last keyword
-that was read.  If it reaches the end of the header without finding the
-keyword, it then goes back to the start of the header and continues the
-search down to the position where it started.  In practice, as long as
-the entire FITS header can fit at one time in the available internal IO
-buffers, then the header keyword access will be relatively fast and it makes
-little difference which order they are accessed.
-
-7. Avoid the use of scaling (by using the BSCALE and BZERO or TSCAL and
-TZERO keywords) in FITS files since the scaling operations add to the
-processing time needed to read or write the data.  In some cases it may
-be more efficient to temporarily turn off the scaling (using fits\_set\_bscale or
-fits\_set\_tscale) and then read or write the raw unscaled values in the FITS
-file.
-
-8. Avoid using the `implicit data type conversion' capability in
-CFITSIO.  For instance, when reading a FITS image with BITPIX = -32
-(32-bit floating point pixels), read the data into a single precision
-floating point data array in the program.  Forcing CFITSIO to convert
-the data to a different data type can slow the program.
-
-9. Where feasible, design FITS binary tables using vector column
-elements so that the data are written as a contiguous set of bytes,
-rather than as single elements in multiple rows.  For example, it is
-faster to access the data in a table that contains a single row
-and 2 columns with TFORM keywords equal to  '10000E' and '10000J', than
-it is to access the same amount of data in a table with 10000 rows
-which has columns with the TFORM keywords equal to '1E' and '1J'.  In
-the former case the 10000 floating point values in the first column are
-all written in a contiguous block of the file which can be read or
-written quickly, whereas in the second case each floating point value
-in the first column is interleaved with the integer value in the second
-column of the same row so CFITSIO has to explicitly move to the
-position of each element to be read or written.
-
-10. Avoid the use of variable length vector columns in binary tables,
-since any reading or writing of these data requires that CFITSIO first
-look up or compute the starting address of each row of data in the
-heap.  In practice, this is probably not a significant efficiency issue.
-
-11. When copying data from one FITS table to another, it is faster to
-transfer the raw bytes instead of reading then writing each column of
-the table.  The CFITSIO routines fits\_read\_tblbytes and
-fits\_write\_tblbytes will perform low-level reads or writes of any
-contiguous range of bytes in a table extension.  These routines can be
-used to read or write a whole row (or multiple rows  for even greater
-efficiency) of a table with a single function call.   These routines
-are fast because they bypass all the usual data scaling, error checking
-and machine dependent data conversion that is normally done by CFITSIO,
-and they allow the program to write the data to the output file in
-exactly the same byte order.  For these same reasons, these routines
-can corrupt the FITS data file if used incorrectly because no
-validation or machine dependent conversion is performed by these
-routines.  These routines are only recommended for optimizing critical
-pieces of code and should only be used by programmers who thoroughly
-understand the internal format of the FITS tables they are reading or
-writing.
-
-12. Another strategy for improving the speed of writing a FITS table,
-similar to the previous one, is to directly construct the entire byte
-stream for a whole table row (or multiple rows) within the application
-program and then write it to the FITS file with
-fits\_write\_tblbytes.  This avoids all the overhead normally present
-in the column-oriented CFITSIO write routines.  This technique should
-only be used for critical applications because it makes the code more
-difficult to understand and maintain, and it makes the code more system
-dependent (e.g., do the bytes need to be swapped before writing to the
-FITS file?).
-
-13.  Finally, external factors such as the speed of the data storage device,
-the size of the data cache, the amount of disk fragmentation, and the amount of
-RAM available on the system can all have a significant impact on
-overall I/O efficiency.  For critical applications, the entire hardware
-and software system should be reviewed to identify any
-potential I/O bottlenecks.

-              cfortran.h :  Interfacing C or C++ and FORTRAN
-
-Supports: Alpha and VAX VMS, Alpha OSF, DECstation and VAX Ultrix, IBM RS/6000, 
-          Silicon Graphics, Sun, CRAY, Apollo, HP9000, LynxOS, Convex, Absoft,
-          f2c, g77, NAG f90, PowerStation Fortran with Visual C++, NEC SX-4,
-          Portland Group.
-
-C and C++ are generally equivalent as far as cfortran.h is concerned.
-Unless explicitly noted otherwise, mention of C implicitly includes C++.
-C++ compilers tested include: 
-  SunOS> CC +p +w      # Clean compiles.
-  IRIX>  CC            # Clean compiles.
-  IRIX>  CC -fullwarn  # Still some warnings to be overcome.
-  GNU>   g++ -Wall     # Compiles are clean, other than warnings for unused
-                       #   cfortran.h static routines.
-
-N.B.: The best documentation on interfacing C or C++ and Fortran is in
-      the chapter named something like 'Interfacing C and Fortran'
-      to be found in the user's guide of almost every Fortran compiler.
-      Understanding this information for one or more Fortran compilers
-      greatly clarifies the aims and actions of cfortran.h.
-      Such a chapter generally also addresses issues orthogonal to cfortran.h,
-      for example the order of array indices, the index of the first element,
-      as well as compiling and linking issues.

-I Introduction
---------------
-
-cfortran.h is an easy-to-use powerful bridge between C and FORTRAN.
-It provides a completely transparent, machine independent interface between
-C and FORTRAN routines (= subroutines and/or functions) and global data,
-i.e. structures and COMMON blocks.
-
-The complete cfortran.h package consists of 4 files: the documentation in
-cfortran.doc, the engine cfortran.h, examples in cfortest.c and 
-cfortex.f/or. [cfortex.for under VMS, cfortex.f on other machines.]
-
-The cfortran.h package continues to be developed. The most recent version is
-available via www at http://www-zeus.desy.de/~burow
-or via anonymous ftp at zebra.desy.de (131.169.2.244).
-
-The examples may be run using one of the following sets of instructions:
-
-N.B. Unlike earlier versions, cfortran.h 3.0 and later versions
-     automatically uses the correct ANSI ## or pre-ANSI /**/
-     preprocessor operator as required by the C compiler.
-
-N.B. As a general rule when trying to determine how to link C and Fortran,
-     link a trivial Fortran program using the Fortran compilers verbose option,
-     in order to see how the Fortran compiler drives the linker. e.g.
-       unix> cat f.f
-                END
-       unix> f77 -v f.f
-       .. lots of info. follows ...
-
-N.B. If using a C main(), i.e. Fortran PROGRAM is not entry of the executable,
-     and if the link bombs with a complaint about
-     a missing "MAIN" (e.g. MAIN__, MAIN_, f90_main or similar),
-     then Fortran has hijacked the entry point to the executable
-     and wishes to call the rest of the executable via "MAIN".
-     This can usually be satisfied by doing e.g. 'cc -Dmain=MAIN__ ...'
-     but often kills the command line arguments in argv and argc.
-     The f77 verbose option, usually -v, may point to a solution.

-
-By changing the SELECTion ifdef of cfortest.c and recompiling one can try out
-a few dozen different few-line examples.
-
-
-
-The benefits of using cfortran.h include:
-1. Machine/OS/compiler independent mixing of C and FORTRAN.
-
-2. Identical (within syntax) calls across languages, e.g.
-C FORTRAN
-      CALL HBOOK1(1,'pT spectrum of pi+',100,0.,5.,0.)
-/* C*/
-           HBOOK1(1,"pT spectrum of pi+",100,0.,5.,0.);
-
-3. Each routine need only be set up once in its lifetime. e.g.
-/* Setting up a FORTRAN routine to be called by C.
-   ID,...,VMX are merely the names of arguments.
-   These tags must be unique w.r.t. each other but are otherwise arbitrary. */
-PROTOCCALLSFSUB6(HBOOK1,hbook1,INT,STRING,INT,FLOAT,FLOAT,FLOAT)
-#define HBOOK1(ID,CHTITLE,NX,XMI,XMA,VMX)                        \
-     CCALLSFSUB6(HBOOK1,hbook1,INT,STRING,INT,FLOAT,FLOAT,FLOAT, \
-               ID,CHTITLE,NX,XMI,XMA,VMX) 
-
-4. Source code is NOT required for the C routines exported to FORTRAN, nor for
-   the FORTRAN routines imported to C. In fact, routines are most easily
-   prototyped using the information in the routines' documentation.
-
-5. Routines, and the code calling them, can be coded naturally in the language
-   of choice. C routines may be coded with the natural assumption of being 
-   called only by C code. cfortran.h does all the required work for FORTRAN 
-   code to call C routines. Similarly it also does all the work required for C
-   to call FORTRAN routines. Therefore:
-     - C programmers need not embed FORTRAN argument passing mechanisms into 
-       their code.
-     - FORTRAN code need not be converted into C code. i.e. The honed and 
-       time-honored FORTRAN routines are called by C.
-
-6. cfortran.h is a single ~1700 line C include file; portable to most
-   remaining, if not all, platforms.
-
-7. STRINGS and VECTORS of STRINGS along with the usual simple arguments to 
-   routines are supported as are functions returning STRINGS or numbers. Arrays
-   of pointers to strings and values of structures as C arguments, will soon be
-   implemented. After learning the machinery of cfortran.h, users can expand 
-   it to create custom types of arguments. [This requires no modification to
-   cfortran.h, all the preprocessor directives required to implement the
-   custom types can be defined outside cfortran.h]
-
-8. cfortran.h requires each routine to be exported to be explicitly set up. 
-   While is usually only be done once in a header file it would be best if
-   applications were required to do no work at all in order to cross languages.
-   cfortran.h's simple syntax could be a convenient back-end for a program
-   which would export FORTRAN or C routines directly from the source code. 
-
-
-                                    -----
-
-Example 1 - cfortran.h has been used to make the C header file hbook.h, 
-            which then gives any C programmer, e.g. example.c, full and 
-            completely transparent access to CERN's HBOOK library of routines.
-            Each HBOOK routine required about 3 lines of simple code in
-            hbook.h. The example also demonstrates how FORTRAN common blocks
-            are defined and used.
-
-/* hbook.h */
-#include "cfortran.h"
-        :
-PROTOCCALLSFSUB6(HBOOK1,hbook1,INT,STRING,INT,FLOAT,FLOAT,FLOAT)

-     CCALLSFSUB6(HBOOK1,hbook1,INT,STRING,INT,FLOAT,FLOAT,FLOAT, \
-               ID,CHTITLE,NX,XMI,XMA,VMX)

-*/
-        :
-  FAKE.p[7]=1.0;
-	:
-}           
-
-N.B. i) The routine is language independent.
-    ii) hbook.h is machine independent.  
-   iii) Applications using routines via cfortran.h are machine independent.
-
-                                    -----
-
-Example 2 - Many VMS System calls are most easily called from FORTRAN, but
-            cfortran.h now gives that ease in C.
-
-#include "cfortran.h"
-
-PROTOCCALLSFSUB3(LIB$SPAWN,lib$spawn,STRING,STRING,STRING)
-#define LIB$SPAWN(command,input_file,output_file)          \
-     CCALLSFSUB3(LIB$SPAWN,lib$spawn,STRING,STRING,STRING, \
-                  command,input_file,output_file)
-
-main ()
-{
-LIB$SPAWN("set term/width=132","","");
-}
-
-Obviously the cfortran.h command above could be put into a header file along
-with the description of the other system calls, but as this example shows, it's
-not much hassle to set up cfortran.h for even a single call.
-
-                                    -----
-
-Example 3 - cfortran.h and the source cstring.c create the cstring.obj library 
-            which gives FORTRAN access to all the functions in C's system 
-            library described by the system's C header file string.h.
-
-C     EXAMPLE.FOR
-      PROGRAM EXAMPLE
-      DIMENSION I(20), J(30)
-        :
-      CALL MEMCPY(I,J,7)
-        :
-      END
-
-/* cstring.c */
-#include <string.h>             /* string.h prototypes memcpy() */
-#include "cfortran.h"
-
-        :
-FCALLSCSUB3(memcpy,MEMCPY,memcpy,PVOID,PVOID,INT)
-        :
-
-
-The simplicity exhibited in the above example exists for many but not all
-machines. Note 4. of Section II ii) details the limitations and describes tools
-which try to maintain the best possible interface when FORTRAN calls C
-routines.

-
-II Using cfortran.h
--------------------
-
-The user is asked to look at the source files cfortest.c and cfortex.f
-for clarification by example.
-
-o) Notes: 
-
-o Specifying the Fortran compiler
-  cfortran.h generates interfaces for the default Fortran compiler. The default
-can be overridden by defining, 
-     . in the code,              e.g.: #define    NAGf90Fortran
-  OR . in the compile directive, e.g.: unix> cc -DNAGf90Fortran
-one of the following before including cfortran.h:
- NAGf90Fortran   f2cFortran  hpuxFortran  apolloFortran  sunFortran
-  IBMR2Fortran  CRAYFortran  mipsFortran     DECFortran  vmsFortran
- CONVEXFortran       PowerStationFortran          AbsoftUNIXFortran
-     SXFortran   pgiFortran                        AbsoftProFortran
-This also allows crosscompilation.
-If wanted, NAGf90Fortran, f2cFortran, DECFortran, AbsoftUNIXFortran,
-AbsoftProFortran and pgiFortran must be requested by the user.
-
-o /**/
-  cfortran.h (ab)uses the comment kludge /**/ when the ANSI C preprocessor
-catenation operator ## doesn't exist. In at least MIPS C, this kludge is
-sensitive to  blanks surrounding arguments to macros.
-  Therefore, for applications using non-ANSI C compilers, the argtype_i,
-routine_name, routine_type and common_block_name arguments to the
-PROTOCCALLSFFUNn, CCALLSFSUB/FUNn, FCALLSCSUB/FUNn and COMMON_BLOCK macros 
---- MUST NOT --- be followed by any white space characters such as
-blanks, tabs or newlines.
-
-o LOGICAL
-  FORTRAN LOGICAL values of .TRUE. and .FALSE. do not agree with the C
-representation of TRUE and FALSE on all machines. cfortran.h does the
-conversion for LOGICAL and PLOGICAL arguments and for functions returning
-LOGICAL. Users must convert arrays of LOGICALs from C to FORTRAN with the 
-C2FLOGICALV(array_name, elements_in_array); macro. Similarly, arrays of LOGICAL
-values may be converted from the FORTRAN into C representation by using
-F2CLOGICALV(array_name, elements_in_array);
-
-  When C passes or returns LOGICAL values to FORTRAN, by default cfortran.h 
-only makes the minimal changes required to the value. [e.g. Set/Unset the 
-single relevant bit or do nothing for FORTRAN compilers which use 0 as FALSE
-and treat all other values as TRUE.] Therefore cfortran.h will pass LOGICALs
-to FORTRAN which do not have an identical representation to .TRUE. or .FALSE.
-This is fine except for abuses of FORTRAN/77 in the style of:
-       logical l
-       if (l .eq. .TRUE.)     ! (1)
-instead of the correct:
-       if (l .eqv. .TRUE.)    ! (2)
-or:
-       if (l)                 ! (3)
-For FORTRAN code which treats LOGICALs from C in the method of (1),
-LOGICAL_STRICT must be defined before including cfortran.h, either in the
-code, "#define LOGICAL_STRICT", or compile with "cc -DLOGICAL_STRICT".
-There is no reason to use LOGICAL_STRICT for FORTRAN code which does not do (1).
-At least the IBM's xlf and the Apollo's f77 do not even allow code along the
-lines of (1).
-
-  DECstations' DECFortran and MIPS FORTRAN compilers use different internal
-representations for LOGICAL values. [Both compilers are usually called f77,
-although when both are installed on a single machine the MIPS' one is usually
-renamed. (e.g. f772.1 for version 2.10.)] cc doesn't know which FORTRAN
-compiler is present, so cfortran.h assumes MIPS f77. To use cc with DECFortran
-define the preprocessor constant 'DECFortran'.
-e.g.        i)  cc -DDECFortran -c the_code.c
-        or  ii) #define DECFortran  /* in the C code or add to cfortran.h. */
-
-  MIPS f77 [SGI and DECstations], f2c, and f77 on VAX Ultrix treat
-.eqv./.neqv. as .eq./.ne.. Therefore, for these compilers, LOGICAL_STRICT is
-defined by default in cfortran.h. [The Sun and HP compilers have not been
-tested, so they may also require LOGICAL_STRICT as the default.]
-
-o SHORT and BYTE 
-  They are irrelevant for the CRAY where FORTRAN has no equivalent to C's short.
-Similarly BYTE is irrelevant for f2c and for VAX Ultrix f77 and fort. The
-author has tested SHORT and BYTE with a modified cfortest.c/cfortex.f on all
-machines supported except for the HP9000 and the Sun.
-
-  BYTE is a signed 8-bit quantity, i.e. values are -128 to 127, on all machines
-except for the SGI [at least for MIPS Computer Systems 2.0.] On the SGI it is
-an unsigned 8-bit quantity, i.e. values are 0 to 255, although the SGI 'FORTRAN
-77 Programmers Guide' claims BYTE is signed. Perhaps MIPS 2.0 is dated, since
-the DECstations using MIPS 2.10 f77 have a signed BYTE.
-
-  To minimize the difficulties of signed and unsigned BYTE, cfortran.h creates
-the type 'INTEGER_BYTE' to agree with FORTRAN's BYTE. Users may define 
-SIGNED_BYTE or UNSIGNED_BYTE, before including cfortran.h, to specify FORTRAN's
-BYTE. If neither is defined, cfortran.h assumes SIGNED_BYTE.
-
-o CRAY
-  The type DOUBLE in cfortran.h corresponds to FORTRAN's DOUBLE PRECISION.
-  The type FLOAT  in cfortran.h corresponds to FORTRAN's REAL.
-
-On a classic CRAY [i.e. all models except for the t3e]:
-( 64 bit) C float       == C double == Fortran REAL
-(128 bit) C long double             == Fortran DOUBLE PRECISION
-Therefore when moving a mixed C and FORTRAN app. to/from a classic CRAY,
-either the C code will have to change,
-or the FORTRAN code and cfortran.h declarations will have to change.
-DOUBLE_PRECISION is a cfortran.h macro which provides the former option,
-i.e. the C code is automatically changed.
-DOUBLE_PRECISION is 'long double' on classic CRAY and 'double' elsewhere.
-DOUBLE_PRECISION thus corresponds to FORTRAN's DOUBLE PRECISION
-on all machines, including classic CRAY.
-
-On a classic CRAY with the fortran compiler flag '-dp':
-Fortran DOUBLE PRECISION thus is also the faster 64bit type.
-(This switch is often used since the application is usually satisfied by
- 64 bit precision and the application needs the speed.)
-DOUBLE_PRECISION is thus not required in this case,
-since the classic CRAY behaves like all other machines.
-If DOUBLE_PRECISION is used nonetheless, then on the classic CRAY
-the default cfortran.h behavior must be overridden,
-for example by the C compiler option '-DDOUBLE_PRECISION=double'.
-
-On a CRAY t3e:
-(32 bit) C float                   == Fortran Unavailable
-(64 bit) C double == C long double == Fortran REAL == Fortran DOUBLE PRECISION
-Notes:
-- (32 bit) is available as Fortran REAL*4 and
-  (64 bit) is available as Fortran REAL*8.
-  Since cfortran.h is all about more portability, not about less portability,
-  the use of the nonstandard REAL*4 and REAL*8 is strongly discouraged.
-- Fortran DOUBLE PRECISION is folded to REAL with the following warning:
-    'DOUBLE PRECISION is not supported on this platform.  REAL will be used.'
-  Similarly, Fortran REAL*16 is mapped to REAL*8 with a warning.
-This behavior differs from that of other machines, including the classic CRAY.
-FORTRAN_REAL is thus introduced for the t3e,
-just as DOUBLE_PRECISION is introduced for the classic CRAY.
-FORTRAN_REAL is 'double' on t3e and 'float' elsewhere.
-FORTRAN_REAL thus corresponds to FORTRAN's REAL on all machines, including t3e.
-
-
-o f2c
-  f2c, by default promotes REAL functions to double. cfortran.h does not (yet)
-support this, so the f2c -R option must be used to turn this promotion off.
-
-o f2c
-[Thanks to Dario Autiero for pointing out the following.]
-f2c has a strange feature in that either one or two underscores are appended
-to a Fortran name of a routine or common block,
-depending on whether or not the original name contains an underscore.
-
-   S.I. Feldman et al., "A fortran to C converter",
-   Computing Science Technical Report No. 149.
-
-   page 2, chapter 2: INTERLANGUAGE conventions
-   ...........
-   To avoid conflict with the names of library routines and with names that
-   f2c generates,
-   Fortran names may have one or two underscores appended. Fortran names are
-   forced to lower case (unless the -U option described in Appendix B is in
-   effect); external names, i.e. the names of fortran procedures and common
-   blocks, have a single underscore appended if they do not contain any
-   underscore and have a pair of underscores appended if they do contain
-   underscores. Thus fortran subroutines names ABC, A_B_C and A_B_C_ result
-   in C functions named abc_, a_b_c__ and a_b_c___.
-   ...........
-
-cfortran.h is unable to change the naming convention on a name by name basis.
-Fortran routine and common block names which do not contain an underscore
-are unaffected by this feature.
-Names which do contain an underscore may use the following work-around:
-
-/* First 2 lines are a completely standard cfortran.h interface
-   to the Fortran routine E_ASY . */
-                  PROTOCCALLSFSUB2(E_ASY,e_asy, PINT, INT)
-#define E_ASY(A,B)     CCALLSFSUB2(E_ASY,e_asy, PINT, INT, A, B)
-#ifdef f2cFortran
-#define e_asy_ e_asy__
-#endif
-/* Last three lines are a work-around for the strange f2c naming feature. */
-
-o NAG f90
-  The Fortran 77 subset of Fortran 90 is supported. Extending cfortran.h to 
-interface C with all of Fortran 90 has not yet been examined.
-  The NAG f90 library hijacks the main() of any program and starts the user's 
-program with a call to: void f90_main(void);
-While this in itself is only a minor hassle, a major problem arises because
-NAG f90 provides no mechanism to access command line arguments.
-  At least version 'NAGWare f90 compiler Version 1.1(334)' appended _CB to
-common block names instead of the usual _. To fix, add this to cfortran.h:
-#ifdef old_NAG_f90_CB_COMMON
-#define COMMON_BLOCK                 CFC_  /* for all other Fortran compilers */
-#else
-#define COMMON_BLOCK(UN,LN)          _(LN,_CB)
-#endif
-
-o RS/6000
-  Using "xlf -qextname ...", which appends an underscore, '_', to all FORTRAN
-external references, requires "cc -Dextname ..." so that cfortran.h also
-generates these underscores.
-Use -Dextname=extname if extname is a symbol used in the C code.
-The use of "xlf -qextname" is STRONGLY ENCOURAGED, since it allows for
-transparent naming schemes when mixing C and Fortran.
-
-o HP9000
-  Using "f77 +ppu      ...", which appends an underscore, '_', to all FORTRAN
-external references, requires "cc -Dextname ..." so that cfortran.h also
-generates these underscores.
-Use -Dextname=extname if extname is a symbol used in the C code.
-The use of "f77 +ppu"      is STRONGLY ENCOURAGED, since it allows for
-transparent naming schemes when mixing C and Fortran.
-
-  At least one release of the HP /lib/cpp.ansi preprocessor is broken and will
-go into an infinite loop when trying to process cfortran.h with the
-## catenation operator. The K&R version of cfortran.h must then be used and the
-K&R preprocessor must be specified. e.g.
-                                         HP9000> cc -Aa -tp,/lib/cpp -c source.c
-The same problem with a similar solution exists on the Apollo.
-An irrelevant error message '0: extraneous name /usr/include' will appear for
-each source file due to another HP bug, and can be safely ignored.
-e.g. 'cc -v -c -Aa -tp,/lib/cpp cfortest.c' will show that the driver passes
-'-I /usr/include' instead of '-I/usr/include' to /lib/cpp
-
-On some machines the above error causes compilation to stop; one must then use
-K&R C, as with old HP compilers which don't support function prototyping.
-cfortran.h has to be informed that K&R C is to being used, e.g.
-HP9000> cc -D__CF__KnR -c source.c
-
-o AbsoftUNIXFortran
-By default, cfortran.h follows the default AbsoftUNIX/ProFortran and prepends _C
-to each COMMON BLOCK name. To override the cfortran.h behavior
-#define COMMON_BLOCK(UN,LN) before #including cfortran.h.
-[Search for COMMON_BLOCK in cfortran.h for examples.]
-
-o Apollo
-On at least one release, 'C compiler 68K Rev6.8(168)', the default C 
-preprocessor, from cc -A xansi or cc -A ansi, enters an infinite loop when 
-using cfortran.h. This Apollo bug can be circumvented by using:
-     . cc -DANSI_C_preprocessor=0 to force use of /**/, instead of '##'.
- AND . The pre-ANSI preprocessor, i.e. use cc -Yp,/usr/lib
-The same problem with a similar solution exists on the HP.
-
-o Sun
-Old versions of cc(1), say <~1986, may require help for cfortran.h applications:
- . #pragma may not be understood, hence cfortran.h and cfortest.c may require
-   sun> mv cfortran.h cftmp.h && grep -v "^#pragma" <cftmp.h >cfortran.h
-   sun> mv cfortest.c cftmp.c && grep -v "^#pragma" <cftmp.c >cfortest.c
- . Old copies of math.h may not include the following from a newer math.h.
-   [For an ancient math.h on a 386 or sparc, get similar from a new math.h.]
-   #ifdef mc68000     /* 5 lines Copyright (c) 1988 by Sun Microsystems, Inc. */
-   #define FLOATFUNCTIONTYPE	int
-   #define RETURNFLOAT(x) 		return (*(int *)(&(x)))
-   #define ASSIGNFLOAT(x,y)	*(int *)(&x) = y
-   #endif
-
-o CRAY, Sun, Apollo [pre 6.8 cc], VAX Ultrix and HP9000
-  Only FORTRAN routines with less than 15 arguments can be prototyped for C,
-since these compilers don't allow more than 31 arguments to a C macro. This can
-be overcome, [see Section IV], with access to any C compiler without this
-limitation, e.g. gcc, on ANY machine.
-
-o VAX Ultrix
-  vcc (1) with f77 is not supported. Although: 
-VAXUltrix> f77 -c cfortex.f
-VAXUltrix> vcc -o cfortest cfortest.c cfortex.o -lI77 -lU77 -lF77  &&  cfortest
-will link and run. However, the FORTRAN standard I/O is NOT merged with the
-stdin and stdout of C, and instead uses the files fort.6 and fort.5. For vcc,
-f77 can't drive the linking, as for gcc and cc, since vcc objects must be
-linked using lk (1).  f77 -v doesn't tell much, and without VAX Ultrix manuals,
-the author can only wait for the info. required.
-
-  fort (1) is not supported. Without VAX Ultrix manuals the author cannot 
-convince vcc/gcc/cc and fort to generate names of routines and COMMON blocks
-that match at the linker, lk (1). i.e. vcc/gcc/cc prepend a single underscore
-to external references, e.g. NAME becomes _NAME, while fort does not modify the
-references. So ... either fort has prepend an underscore to external
-references, or vcc/gcc/cc have to generate unmodified names. man 1 fort
-mentions JBL, is JBL the only way?
-
-o VAX VMS C
-  The compiler 'easily' exhausts its table space and generates:
-%CC-F-BUGCHECK, Compiler bug check during parser phase    .
-                Submit an SPR with a problem description.
-                At line number 777 in DISK:[DIR]FILE.C;1.
-where the line given, '777', includes a call across C and FORTRAN via
-cfortran.h, usually with >7 arguments and/or very long argument expressions.
-This SPR can be staved off, with the simple modification to cfortran.h, such
-that the relevant CCALLSFSUBn (or CCALLSFFUNn or FCALLSCFUNn) is not
-cascaded up to CCALLSFSUB14, and instead has its own copy of the contents of 
-CCALLSFSUB14. [If these instructions are not obvious after examining cfortran.h
-please contact the author.]
-[Thanks go to Mark Kyprianou (kyp@stsci.edu) for this solution.]
-
-o Mips compilers
-  e.g. DECstations and SGI, require applications with a C main() and calls to
-GETARG(3F), i.e. FORTRAN routines returning the command line arguments, to use
-two macros as shown:
-        :
-CF_DECLARE_GETARG;              /* This must be external to all routines.     */
-        :
-main(int argc, char *argv[])
-{
-        :
-CF_SET_GETARG(argc,argv);       /* This must precede any calls to GETARG(3F). */
-        :
-}
-The macros are null and benign on all other systems. Sun's GETARG(3F) also
-doesn't work with a generic C main() and perhaps a workaround similar to the
-Mips' one exists.
-
-o Alpha/OSF
-Using the DEC Fortran and the DEC C compilers of DEC OSF/1 [RT] V1.2 (Rev. 10),
-Fortran, when called from C, has occasional trouble using a routine received as
-a dummy argument.
-
-e.g. In the following the Fortran routine 'e' will crash when it tries to use
-     the C routine 'c' or the Fortran routine 'f'.
-     The example works on other systems.
-
-C FORTRAN                           /* C */
-      integer function f()          #include <stdio.h>
-      f = 2                         int f_();
-      return                        int e_(int (*u)());
-      end
-                                    int c(){ return 1;}
-      integer function e(u)         int d (int (*u)()) { return u();}
-      integer u
-      external u                    main()
-      e=u()                         {         /* Calls to d  work.  */
-      return                        printf("d (c ) returns %d.\n",d (c ));
-      end                           printf("d (f_) returns %d.\n",d (f_));
-                                              /* Calls to e_ crash. */
-                                    printf("e_(c ) returns %d.\n",e_(c ));
-                                    printf("e_(f_) returns %d.\n",e_(f_));
-                                    }
-
-Solutions to the problem are welcomed!
-A kludge which allows the above example to work correctly, requires an extra
-argument to be given when calling the dummy argument function.
-i.e. Replacing 'e=u()' by 'e=u(1)' allows the above example to work.
-
-
-o The FORTRAN routines are called using macro expansions, therefore the usual
-caveats for expressions in arguments apply. The expressions to the routines may
-be evaluated more than once, leading to lower performance and in the worst case
-bizarre bugs.
-
-o For those who wish to use cfortran.h in large applications. [See Section IV.]
-This release is intended to make it easy to get applications up and running. 
-This implies that applications are not as efficient as they could be:
-- The current mechanism is inefficient if a single header file is used to
-  describe a large library of FORTRAN functions. Code for a static wrapper fn.
-  is generated in each piece of C source code for each FORTRAN function 
-  specified with the CCALLSFFUNn statement, irrespective of whether or not the
-  function is ever called. 
-- Code for several static utility routines internal to cfortran.h is placed 
-  into any source code which #includes cfortran.h. These routines should
-  probably be in a library.
-
-
-i) Calling FORTRAN routines from C:
-   --------------------------------
-
-The FORTRAN routines are defined by one of the following two instructions:
-
-for a SUBROUTINE:
-/* PROTOCCALLSFSUBn is optional for C, but mandatory for C++. */
-PROTOCCALLSFSUBn(ROUTINE_NAME,routine_name,argtype_1,...,argtype_n)
-#define     Routine_name(argname_1,..,argname_n)               \
-CCALLSFSUBn(ROUTINE_NAME,routine_name,argtype_1,...,argtype_n, \
-                         argname_1,..,argname_n) 
-
-for a FUNCTION:
-PROTOCCALLSFFUNn(routine_type,ROUTINE_NAME,routine_name,argtype_1,...,argtype_n)
-#define     Routine_name(argname_1,..,argname_n)               \
-CCALLSFFUNn(ROUTINE_NAME,routine_name,argtype_1,...,argtype_n, \
-                         argname_1,..,argname_n) 
-
-Where:
-'n' = 0->14 [SUBROUTINE's ->27] (easily expanded in cfortran.h to > 14 [27]) is 
-    the number of arguments to the routine.
-Routine_name = C       name of the routine (IN UPPER CASE LETTERS).[see 2.below]
-ROUTINE_NAME = FORTRAN name of the routine (IN UPPER CASE LETTERS).
-routine_name = FORTRAN name of the routine (IN lower case LETTERS).
-routine_type = the type of argument returned by FORTRAN functions.
-             = BYTE, DOUBLE, FLOAT, INT, LOGICAL, LONG, SHORT, STRING, VOID.
-               [Instead of VOID one would usually use CCALLSFSUBn.
-                VOID forces a wrapper function to be used.]
-argtype_i    = the type of argument passed to the FORTRAN routine and must be
-               consistent in the definition and prototyping of the routine s.a.
-             = BYTE, DOUBLE, FLOAT, INT, LOGICAL, LONG, SHORT, STRING.
-             For vectors, i.e. 1 dim. arrays use 
-             = BYTEV, DOUBLEV, FLOATV, INTV, LOGICALV, LONGV, SHORTV, 
-               STRINGV, ZTRINGV.
-             For vectors of vectors, i.e. 2 dim. arrays use
-             = BYTEVV, DOUBLEVV, FLOATVV, INTVV, LOGICALVV, LONGVV, SHORTVV.
-             For n-dim. arrays, 1<=n<=7 [7 is the maximum in Fortran 77],
-             = BYTEV..nV's..V, DOUBLEV..V, FLOATV..V, INTV..V, LOGICALV..V, 
-               LONGV..V, SHORTV..V.
-                N.B. Array dimensions and types are checked by the C compiler.
-             For routines changing the values of an argument, the keyword is 
-                  prepended by a 'P'.
-             = PBYTE, PDOUBLE, PFLOAT, PINT, PLOGICAL, PLONG, PSHORT,
-               PSTRING, PSTRINGV, PZTRINGV.
-             For EXTERNAL procedures passed as arguments use
-             = ROUTINE.
-             For exceptional arguments which require no massaging to fit the
-                  argument passing mechanisms use
-             = PVOID.
-                The argument is cast and passed as (void *).
-                Although PVOID could be used to describe all array arguments on
-                most (all?) machines , it shouldn't be because the C compiler
-                can no longer check the type and dimension of the array.
-argname_i    = any valid unique C tag, but must be consistent in the definition 
-               as shown.
-
-Notes:
-
-1. cfortran.h may be expanded to handle a more argument type. To suppport new
-arguments requiring complicated massaging when passed  between Fortran and C,
-the user will have to understand cfortran.h and follow its code and mechanisms.
-
-To define types requiring little or no massaging when passed between Fortran 
-and C, the pseudo argument type SIMPLE may be used.
-For a user defined type called 'newtype', the definitions required are:
-
-/* The following 7 lines are required verbatim.
-   'newtype' is the name of the new user defined argument type.
-*/
-#define newtype_cfV(  T,A,B,F)       SIMPLE_cfV(T,A,B,F)
-#define newtype_cfSEP(T,  B)         SIMPLE_cfSEP(T,B)
-#define newtype_cfINT(N,A,B,X,Y,Z)   SIMPLE_cfINT(N,A,B,X,Y,Z)
-#define newtype_cfSTR(N,T,A,B,C,D,E) SIMPLE_cfSTR(N,T,A,B,C,D,E)
-#define newtype_cfCC( T,A,B)         SIMPLE_cfCC(T,A,B)
-#define newtype_cfAA( T,A,B)         newtype_cfB(T,A) /* Argument B not used. */
-#define newtype_cfU(  T,A)           newtype_cfN(T,A)
-
-/* 'parameter_type(A)' is a declaration for 'A' and describes the type of the 
-parameter expected by the Fortran function.  This type will be used in the
-prototype for the function, if  using ANSI C, and to declare the argument used
-by the intermediate function if calling a Fortran FUNCTION.
-Valid 'parameter_type(A)' include: int A
-                                   void (*A)()
-                                   double A[17]
-*/
-#define newtype_cfN(  T,A)     parameter_type(A)      /* Argument T not used. */
-
-/* Before any argument of the new type is passed to the Fortran routine, it may
-be massaged as given by 'massage(A)'.
-*/
-#define newtype_cfB(  T,A)     massage(A)             /* Argument T not used. */
-
-An example of a simple user defined type is given cfortex.f and cfortest.c.
-Two uses of SIMPLE user defined types are [don't show the 7 verbatim #defines]:
-
-/* Pass the address of a structure, using a type called PSTRUCT */
-#define PSTRUCT_cfN(  T,A)        void *A
-#define PSTRUCT_cfB(  T,A)       (void *) &(A)
-
-/* Pass an integer by value, (not standard F77 ), using a type called INTVAL */
-#define INTVAL_cfN(   T,A)      int A
-#define INTVAL_cfB(   T,A)         (A)
-
-[If using VAX VMS, surrounding the #defines with "#pragma (no)standard" allows
- the %CC-I-PARAMNOTUSED messages to be avoided.]
-
-Upgrades to cfortran.h try to be, and have been, backwards compatible. This
-compatibility cannot be offered to user defined types. SIMPLE user defined 
-types are less of a risk since they require so little effort in their creation.
-If a user defined type is required in more than one C header file of interfaces
-to libraries of Fortran routines, good programming practice, and ease of code
-maintenance, suggests keeping any user defined type within a single file which
-is #included as required. To date, changes to the SIMPLE macros were introduced
-in versions 2.6, 3.0 and 3.2 of cfortran.h.
-
-
-2. Routine_name is the name of the macro which the C programmer will use in
-order to call a FORTRAN routine. In theory Routine_name could be any valid and
-unique name, but in practice, the name of the FORTRAN routine in UPPER CASE
-works everywhere and would seem to be an obvious choice.
-
-
-3. <BYTE|DOUBLE|BYTE|DOUBLE|FLOAT|INT|LOGICAL|LONG|SHORT><V|VV|VVV|...>
-
-cfortran.h encourages the exact specification of the type and dimension of
-array parameters because it allows the C compiler to detect errors in the
-arguments when calling the routine.
-
-cfortran.h does not strictly require the exact specification since the argument 
-is merely the address of the array and is passed on to the calling routine.
-Any array parameter could be declared as PVOID, but this circumvents
-C's compiletime ability to check the correctness of arguments and is therefore
-discouraged.
-
-Passing the address of these arguments implies that PBYTEV, PFLOATV, ... ,
-PDOUBLEVV, ... don't exist in cfortran.h, since by default the routine and the
-calling code share the same array, i.e. the same values at the same memory
-location.
-
-These comments do NOT apply to arrays of (P)S/ZTRINGV. For these parameters,
-cfortran.h passes a massaged copy of the array to the routine. When the routine
-returns, S/ZTRINGV ignores the copy, while PS/ZTRINGV replaces the calling
-code's original array with copy, which may have been modified by the called
-routine.
-
-
-4. (P)STRING(V):
-- STRING - If the argument is a fixed length character array, e.g. char ar[8];,
-the string is blank, ' ', padded on the right to fill out the array before
-being passed to the FORTRAN routine. The useful size of the string is the same
-in both languages, e.g. ar[8] is passed as character*7. If the argument is a
-pointer, the string cannot be blank padded, so the length is passed as
-strlen(argument). On return from the FORTRAN routine, pointer arguments are not
-disturbed, but arrays have the terminating '\0' replaced to its original
-position. i.e. The padding blanks are never visible to the C code.
-
-- PSTRING - The argument is massaged as with STRING before being passed to the
-FORTRAN routine. On return, the argument has all trailing blanks removed,
-regardless of whether the argument was a pointer or an array.
-
-- (P)STRINGV - Passes a 1- or 2-dimensional char array. e.g. char a[7],b[6][8];
-STRINGV may thus also pass a string constant, e.g. "hiho".
-(P)STRINGV does NOT pass a pointer, e.g. char *, to either a 1- or a
-2-dimensional array, since it cannot determine the array dimensions.
-A pointer can only be passed using (P)ZTRINGV.
-N.B. If a C routine receives a character array argument, e.g. char a[2][3],
-     such an argument is actually a pointer and my thus not be passed by
-     (P)STRINGV. Instead (P)ZTRINGV must be used.
-
-- STRINGV - The elements of the argument are copied into space malloc'd, and
-each element is padded with blanks. The useful size of each element is the same
-in both languages. Therefore char bb[6][8]; is equivalent to character*7 bb(6).
-On return from the routine the malloc'd space is simply released.
-
-- PSTRINGV - Since FORTRAN has no trailing '\0', elements in an array of
-strings are contiguous. Therefore each element of the C array is padded with
-blanks and strip out C's trailing '\0'. After returning from the routine, the
-trailing '\0' is reinserted and kill the trailing blanks in each element.
-
-- SUMMARY: STRING(V) arguments are blank padded during the call to the FORTRAN
-routine, but remain original in the C code. (P)STRINGV arguments are blank
-padded for the FORTRAN call, and after returning from FORTRAN trailing blanks
-are stripped off.
-
-
-5. (P)ZTRINGV:
-- (P)ZTRINGV - is identical to (P)STRINGV,
-except that the dimensions of the array of strings is explicitly specified,
-which thus also allows a pointer to be passed.
-(P)ZTRINGV can thus pass a 1- or 2-dimensional char array, e.g. char b[6][8],
-or it can pass a pointer to such an array, e.g. char *p;.
-ZTRINGV may thus also pass a string constant, e.g. "hiho".
-If passing a 1-dimensional array, routine_name_ELEMS_j (see below) must be 1.
-[Users of (P)ZTRINGV should examine cfortest.c for examples.]:
-
-- (P)ZTRINGV must thus be used instead of (P)STRINGV whenever sizeof()
-can't be used to determine the dimensions of the array of string or strings.
-e.g. when calling FORTRAN from C with a char * received by C as an argument.
-
-- There is no (P)ZTRING type, since (P)ZTRINGV can pass a 1-dimensional
-array or a pointer to such an array, e.g. char a[7], *b;
-If passing a 1-dimensional array, routine_name_ELEMS_j (see below) must be 1.
-
-- To specify the numbers of elements,
-routine_name_ELEMS_j and routine_name_ELEMLEN_j must be defined as shown below
-before interfacing the routine with CCALLSFSUBn, PROTOCCALLSFFUNn, etc.
-
-#define routine_name_ELEMS_j   ZTRINGV_ARGS(k)       
-                                 [..ARGS for subroutines, ..ARGF for functions.]

-#define routine_name_ELEMS_j   ZTRINGV_NUM(l)
-Where: routine_name is as above.
-       j            [1-n], is the argument being specifying.
-       k            [1-n], the value of the k'th argument is the dynamic number
-                    of elements for argument j. The k'th argument must be
-                    of type BYTE, DOUBLE, FLOAT, INT, LONG or SHORT.
-       l            the number of elements for argument j. This must be an
-                    integer constant available at compile time.
-                    i.e. it is static.
-
-- Similarly to specify the useful length, [i.e. don't count C's trailing '\0',]
-of each element:
-#define routine_name_ELEMLEN_j ZTRINGV_ARGS(m)
-                                 [..ARGS for subroutines, ..ARGF for functions.]
-or
-#define routine_name_ELEMLEN_j ZTRINGV_NUM(q)
-Where: m            [1-n], as for k but this is the length of each element. 
-       q            as for l but this is the length of each element. 
-
-
-6. ROUTINE
-The argument is an EXTERNAL procedure.
-
-When C passes a routine to Fortran, the language of the function must be
-specified as follows:  [The case of some_*_function must be given as shown.]
-
-When C passes a C routine to a Fortran: 
-    FORTRAN_ROUTINE(arg1, .... ,       
-                    C_FUNCTION(SOME_C_FUNCTION,some_c_function),
-                    ...., argn);
-
-and similarly when C passes a Fortran routine to Fortran:
-    FORTRAN_ROUTINE(arg1, .... ,
-                    FORTRAN_FUNCTION(SOME_FORT_FUNCTION,some_fort_function),
-                    ...., argn);
-
-If fcallsc has been redefined; the same definition of fcallsc used when creating
-the wrapper for 'some_c_function' must also be defined when C_FUNCTION is used.
-See ii) 4. of this section for when and how to redefine fcallsc.
-
-ROUTINE was introduced with cfortran.h version 2.6. Earlier versions of
-cfortran.h used PVOID to pass external procedures as arguments. Using PVOID for
-this purpose is no longer recommended since it won't work 'as is' for
-apolloFortran, hpuxFortran800, AbsoftUNIXFortran, AbsoftProFortran.
-
-7. CRAY only: 
-In a given piece of source code, where FFUNC is any FORTRAN routine,
-FORTRAN_FUNCTION(FFUNC,ffunc)
-disallows a previous 
-#define FFUNC(..) CCALLSFSUBn(FFUNC,ffunc,...) [ or CCALLSFFUNn]
-in order to make the UPPER CASE FFUNC callable from C.
-#define Ffunc(..) ... is OK though, as are obviously any other names.
-
-
-ii) Calling C routines from FORTRAN:
-    --------------------------------
-
-Each of the following two statements to export a C routine to FORTRAN create
-FORTRAN 'wrappers', written in C, which must be compiled and linked along with
-the original C routines and with the FORTRAN calling code.
-
-FORTRAN callable 'wrappers' may also be created for C macros. i.e. in this
-section, the term 'C function' may be replaced by 'C macro'.
-
-for C functions returning void:
-FCALLSCSUBn(             Routine_name,ROUTINE_NAME,routine_name,argtype_1,...,argtype_n)
-
-for all other C functions:
-FCALLSCFUNn(routine_type,Routine_name,ROUTINE_NAME,routine_name,argtype_1,...,argtype_n)
-
-Where:
-'n' = 0->27 (easily expanded to > 27) stands for the number of arguments to the 
-    routine.
-Routine_name = the C       name of the routine. [see 9. below]
-ROUTINE_NAME = the FORTRAN name of the routine (IN UPPER CASE LETTERS).
-routine_name = the FORTRAN name of the routine (IN lower case LETTERS).
-routine_type = the type of argument returned by C functions.
-             = BYTE, DOUBLE, FLOAT, INT, LOGICAL, LONG, SHORT, STRING, VOID.
-               [Instead of VOID, FCALLSCSUBn is recommended.]
-argtype_i    = the type of argument passed to the FORTRAN routine and must be
-               consistent in the definition and prototyping of the routine
-             = BYTE, DOUBLE, FLOAT, INT, LOGICAL, LONG, SHORT, STRING.
-             For vectors, i.e. 1 dim. arrays use 
-             = BYTEV, DOUBLEV, FLOATV, INTV, LOGICALV, LONGV, SHORTV, STRINGV.
-             For vectors of vectors, 2 dim. arrays use
-             = BYTEVV, DOUBLEVV, FLOATVV, INTVV, LOGICALVV, LONGVV, SHORTVV.
-             For n-dim. arrays use
-             = BYTEV..nV's..V, DOUBLEV..V, FLOATV..V, INTV..V, LOGICALV..V, 
-               LONGV..V, SHORTV..V.
-             For routines changing the values of an argument, the keyword is 
-                  prepended by a 'P'.
-             = PBYTE, PDOUBLE, PFLOAT, PINT, PLOGICAL, PLONG, PSHORT, 
-               PSTRING, PNSTRING, PPSTRING, PSTRINGV.
-             For EXTERNAL procedures passed as arguments use
-             = ROUTINE.
-             For exceptional arguments which require no massaging to fit the
-                  argument passing mechanisms use
-             = PVOID.
-                The argument is cast and passed as (void *).
-
-
-Notes:
-
-0. For Fortran calling C++ routines, C++ does NOT easily allow support for: 
-   STRINGV.
-   BYTEVV, DOUBLEVV, FLOATVV, INTVV, LOGICALVV, LONGVV, SHORTVV.
-   BYTEV..V, DOUBLEV..V, FLOATV..V, INTV..V, LOGICALV..V, LONGV..V, SHORTV..V.
-Though there are ways to get around this restriction,
-the restriction is not serious since these types are unlikely to be used as
-arguments for a C++ routine.
-
-1. FCALLSCSUB/FUNn expect that the routine to be 'wrapped' has been properly
-prototyped, or at least declared.
-
-
-2. cfortran.h may be expanded to handle a new argument type not already among
-the above. 
-
-
-3. <BYTE|DOUBLE|BYTE|DOUBLE|FLOAT|INT|LOGICAL|LONG|SHORT><V|VV|VVV|...>
-
-cfortran.h encourages the exact specification of the type and dimension of
-array parameters because it allows the C compiler to detect errors in the
-arguments when declaring the routine using FCALLSCSUB/FUNn, assuming the
-routine to be 'wrapped' has been properly prototyped.
-
-cfortran.h does not strictly require the exact specification since the argument 
-is merely the address of the array and is passed on to the calling routine.
-Any array parameter could be declared as PVOID, but this circumvents
-C's compiletime ability to check the correctness of arguments and is therefore
-discouraged.
-
-Passing the address of these arguments implies that PBYTEV, PFLOATV, ... ,
-PDOUBLEVV, ... don't exist in cfortran.h, since by default the routine and the
-calling code share the same array, i.e. the same values at the same memory
-location.
-
-These comments do NOT apply to arrays of (P)STRINGV. For these parameters,
-cfortran.h passes a massaged copy of the array to the routine. When the routine
-returns, STRINGV ignores the copy, while PSTRINGV replaces the calling
-code's original array with copy, which may have been modified by the called
-routine.
-
-
-4. (P(N))STRING arguments have any trailing blanks removed before being passed
-to C, the same holds true for each element in (P)STRINGV. Space is malloc'd in
-all cases big enough to hold the original string (elements) as well as C's
-terminating '\0'. i.e. The useful size of the string (elements) is the same in
-both languages. P(N)STRING(V) => the string (elements) will be copied from the
-malloc'd space back into the FORTRAN bytes. If one of the two escape mechanisms
-mentioned below for PNSTRING has been used, the copying back to FORTRAN is
-obviously not relevant.
-
-
-5. (PN)STRING's, [NOT PSTRING's nor (P)STRINGV's,] behavior may be overridden
-in two cases.  In both cases PNSTRING and STRING behave identically.
-
-a) If a (PN)STRING argument's first 4 bytes are all the NUL character,
-i.e. '\0\0\0\0' the NULL pointer is passed to the C routine.
-
-b) If the characters of a (PN)STRING argument contain at least one HEX-00, i.e.
-the NUL character, i.e. C strings' terminating '\0', the address of the string
-is simply passed to the C routine. i.e. The argument is treated in this case as
-it would be with PPSTRING, to which we refer the reader for more detail.
-
-Mechanism a) overrides b). Therefore, to use this mechanism to pass the NULL
-string, "", to C, the first character of the string must obviously be the NUL
-character, but of the first 4 characters in the string, at least one must not
-be HEX-00.
-
-Example:
-C FORTRAN                         /* C */
-      character*40 str            #include "cfortran.h"
-C Set up a NULL as :              void cs(char *s) {if (s) printf("%s.\n",s);}
-C    i)  4 NUL characters.        FCALLSCSUB1(cs,CS,cs,STRING)
-C    ii) NULL pointer.
-      character*4 NULL        
-      NULL = CHAR(0)//CHAR(0)//CHAR(0)//CHAR(0)
-
-      data str/'just some string'/
-
-C Passing the NULL pointer to cs.
-      call cs(NULL)
-C Passing a copy of 'str' to cs.
-      call cs(str)
-C Passing address of 'str' to cs. Trailing blanks NOT killed.
-      str(40:) = NULL
-      call cs(str)
-      end
-
-Strings passed from Fortran to C via (PN)STRING must not have undefined
-contents, otherwise undefined behavior will result, since one of the above two
-escape mechanisms may occur depending on the contents of the string.
-
-This is not be a problem for STRING arguments, which are read-only in the C
-routine and hence must have a well defined value when being passed in.
-
-PNSTRING arguments require special care. Even if they are write-only in the C
-routine, PNSTRING's above two escape mechanisms require that the value of the
-argument be well defined when being passed in from Fortran to C. Therefore,
-unless one or both of PNSTRING's escape mechanisms are required, PSTRING should
-be used instead of PNSTRING.
-Prior to version 2.8, PSTRING did have the above two escape mechanisms,
-but they were removed from PSTRING to allow strings with undefined contents to
-be passed in. PNSTRING behaves like the old PSTRING.
-[Thanks go to Paul Dubois (dubios@icf.llnl.gov) for pointing out that PSTRING
- must allow for strings with undefined contents to be passed in.]
-
-Example:
-C FORTRAN                         /* C */
-      character*10 s,sn           #include "cfortran.h"
-                                  void ps(char *s) {strcpy(s,"hello");}
-C Can   call ps  with undef. s.   FCALLSCSUB1(ps,PS,ps,PSTRING)
-      call ps(s)                  FCALLSCSUB1(ps,PNS,pns,PNSTRING)
-      print *,s,'=s'
-                              
-C Can't call pns with undef. s.
-C e.g. If first 4 bytes of s were
-C      "\0\0\0\0", ps would try
-C      to copy to NULL because
-C      of PNSTRING mechanism.
-      sn = ""
-      call pns(sn)
-      print *,sn,'=sn'
-                                               
-      end
-
-
-6. PPSTRING
-The address of the string argument is simply passed to the C routine. Therefore
-the C routine and the FORTRAN calling code share the same string at the same
-memory location. If the C routine modifies the string, the string will also be
-modified for the FORTRAN calling code.
-The user is responsible for negociating the differences in representation of a
-string in Fortran and in C, i.e. the differences are not automatically resolved
-as they are for (P(N)STRING(V).
-This mechanism is provided for two reasons:
-   - Some C routines require the string to exist at the given memory location, 
-     after the C routine has exited. Recall that for the usual (P(N)STRING(V)
-     mechanism, a copy of the FORTRAN string is given to the C routine, and this
-     copy ceases to exist after returning to the FORTRAN calling code.
-   - This mechanism can save runtime CPU cycles over (P(N)STRING(V), since it
-     does not perform their malloc, copy and kill trailing blanks of the string
-     to be passed.
-     Only in a small minority of cases does the potential benefit of the saved
-     CPU cycles outweigh the programming effort required to manually resolve
-     the differences in representation of a string in Fortran and in C.
-
-For arguments passed via PPSTRING, the argument passed may also be an array of
-strings.
-
-
-7. ROUTINE
-ANSI C requires that the type of the value returned by the routine be known,
-For all ROUTINE arguments passed from Fortran to C, the type of ROUTINE is
-specified by defining a cast as follows:
-
-#undef  ROUTINE_j
-#define ROUTINE_j   (cast)
-where:
-       j            [1-n], is the argument being specifying.
-       (cast)       is a cast matching that of the argument expected by the C
-                    function protoytpe for which a wrapper is being defined.
-
-e.g. To create a Fortran wrapper for qsort(3C):
-#undef  ROUTINE_4
-#define ROUTINE_4 (int (*)(void *,void *))
-FCALLSCSUB4(qsort,FQSORT,fqsort,PVOID,INT,INT,ROUTINE)
-
-In order to maintain backward compatibility, cfortran.h defines a generic cast
-for ROUTINE_1, ROUTINE_2, ..., ROUTINE_27. The user's definition is therefore
-strictly required only for DEC C, which at the moment is the only compiler
-which insists on the correct cast for pointers to functions.
-
-When using the ROUTINE argument inside some Fortran code:
-- it is difficult to pass a C routine as the parameter,
-  since in many Fortran implementations,
-  Fortran has no access to the normal C namespace.
-  e.g. For most UNIX,
-       Fortran implicitly only has access to C routines ending in _.
-  If the calling Fortran code receives the routine as a parameter
-  it can of course easily pass it along.
-- if a Fortran routine is passed directly as the parameter,
-  the called C routine must call the parameter routine
-  using the Fortran argument passing conventions.
-- if a Fortran routine is to be passed as the parameter,
-  but if Fortran can be made to pass a C routine as the parameter,
-  then it may be best to pass a C-callable wrapper for the Fortran routine.
-  The called C routine is thus spared all Fortran argument passing conventions.
-  cfortran.h can be used to create such a C-callable wrapper
-  to the parameter Fortran routine.
-
-ONLY PowerStationFortran:
-This Fortran provides no easy way to pass a Fortran routine as an argument to a
-C routine. The problem arises because in Fortran the stack is cleared by the
-called routine, while in C/C++ it is cleared by the caller.
-The C/C++ stack clearing behavior can be changed to that of Fortran by using
-stdcall__ in the function prototype. The stdcall__ cannot be applied in this
-case since the called C routine expects the ROUTINE parameter to be a C routine
-and does not know that it should apply stdcall__.
-In principle the cfortran.h generated Fortran callable wrapper for the called C
-routine should be able to massage the ROUTINE argument such that stdcall__ is
-performed, but it is not yet known how this could be easily done.
-
-
-8. THE FOLLOWING INSTRUCTIONS ARE NOT REQUIRED FOR VAX VMS
-                                  ------------
-(P)STRINGV information [NOT required for VAX VMS]: cfortran.h cannot convert
-the FORTRAN vector of STRINGS to the required C vector of STRINGS without
-explicitly knowing the number of elements in the vector. The application must
-do one of the following for each (P)STRINGV argument in a routine before that
-routine's FCALLSCFUNn/SUBn is called:
-
-#define routine_name_STRV_Ai NUM_ELEMS(j)
- or
-#define routine_name_STRV_Ai NUM_ELEM_ARG(k)
- or
-#define routine_name_STRV_Ai TERM_CHARS(l,m)
-
-where: routine_name     is as above.
-       i [i=1->n.]      specifies the argument number of a STRING VECTOR.
-       j                would specify a fixed number of elements. 
-       k [k=1->n. k!=i] would specify an integer argument which specifies the
-                        number of elements.
-       l [char]         the terminating character at the beginning of an
-                        element, indicating to cfortran.h that the preceding
-                        elements in the vector are the valid ones.
-       m [m=1-...]      the number of terminating characters required to appear
-                        at the beginning of the terminating string element.
-                        The terminating element is NOT passed on to 
-                        the C routine.
-
-e.g.      #define ce_STRV_A1 TERM_CHARS(' ',2)
-          FCALLSCSUB1(ce,CE,ce,STRINGV)
-
-cfortran.h will pass on all elements, in the 1st and only argument to the C
-routine ce, of the STRING VECTOR until, but not including, the first string
-element beginning with 2 blank, ' ', characters.
-
-
-9. INSTRUCTIONS REQUIRED ONLY FOR FORTRAN COMPILERS WHICH GENERATE
-                -------------     
-   ROUTINE NAMES WHICH ARE UNDISTINGUISHABLE FROM C ROUTINE NAMES
-   i.e. VAX VMS
-        AbsoftUNIXFortran (AbsoftProFortran ok, since it uses Uppercase names.)
-        HP9000      if not using the +ppu      option of f77
-        IBM RS/6000 if not using the -qextname option of xlf
-   Call them the same_namespace compilers.
-
-FCALLSCSUBn(...) and FCALLSCFUNn(...), when compiled, are expanded into
-'wrapper' functions, so called because they wrap around the original C 
-functions and interface the format of the original C functions' arguments and
-return values with the format of the FORTRAN call.
-
-Ideally one wants to be able to call the C routine from FORTRAN using the same
-name as the original C name. This is not a problem for FORTRAN compilers which
-append an underscore, '_', to the names of routines, since the original C
-routine has the name 'name', and the FORTRAN wrapper is called 'name_'.
-Similarly, if the FORTRAN compiler generates upper case names for routines, the
-original C routine 'name' can have a wrapper called 'NAME', [Assuming the C
-routine name is not in upper case.] For these compilers, e.g. Mips, CRAY, IBM
-RS/6000 'xlf -qextname', HP-UX 'f77 +ppu', the naming of the wrappers is done
-automatically.
-
-For same_namespace compilers things are not as simple, but cfortran.h tries to
-provide tools and guidelines to minimize the costs involved in meeting their
-constraints. The following two options can provide same_namespace compilers
-with distinct names for the wrapper and the original C function.
-
-These compilers are flagged by cfortran.h with the CF_SAME_NAMESPACE  constant,
-so that the change in the C name occurs only when required.
-
-For the remainder of the discussion, routine names generated by FORTRAN
-compilers are referred to in lower case, these names should be read as upper
-case for the appropriate compilers.
-
-
-HP9000: (When f77 +ppu is not used.)
-f77 has a -U option which forces uppercase external names to be generated.
-Unfortunately, cc does not handle recursive macros. Hence, if one wished to use
--U for separate C and FORTRAN namespaces, one would have to adopt a different
-convention of naming the macros which allow C to call FORTRAN subroutines.
-(Functions are not a problem.) The macros are currently the uppercase of the
-original FORTRAN name, and would have to be changed to lower case or mixed
-case, or to a different name. (Lower case would of course cause conflicts on
-many other machines.) Therefore, it is suggested that f77 -U  not be used, and
-instead that Option a) or Option b) outlined below be used.
-
-
-VAX/VMS:
-For the name used by FORTRAN in calling a C routine to be the same as that of
-the C routine, the source code of the C routine is required. A preprocessor
-directive can then force the C compiler to generate a different name for the C
-routine. 
-e.g.                #if defined(vms)
-                    #define name name_
-                    #endif
-                    void name() {printf("name: was called.\n");}
-                    FCALLSCSUB0(name,NAME,name)
-
-In the above, the C compiler generates the original routine with the name
-'name_' and a wrapper called 'NAME'. This assumes that the name of the routine,
-as seen by the C programmer, is not in upper case. The VAX VMS linker is not
-case sensitive, allowing cfortran.h to export the upper case name as the
-wrapper, which then doesn't conflict with the routine name in C. Since the IBM,
-HP and AbsoftUNIXFortran platforms have case sensitive linkers
-this technique is not available to them.
-
-The above technique is required even if the C name is in mixed case, see 
-Option a) for the other compilers, but is obviously not required when 
-Option b) is used.
-
-
-Option a) Mixed Case names for the C routines to be called by FORTRAN.
-
-If the original C routines have mixed case names, there are no name space
-conflicts.
-
-Nevertheless for VAX/VMS, the technique outlined above must also used.
-
-
-Option b) Modifying the names of C routines when used by FORTRAN:
-
-The more robust naming mechanism, which guarantees portability to all machines, 
-'renames' C routines when called by FORTRAN. Indeed, one must change the names
-on same_namespace compilers when FORTRAN calls C routines for which the source
-is unavailable. [Even when the source is available, renaming may be preferable
-to Option a) for large libraries of C routines.]
-
-Obviously, if done for a single type of machine, it must be done for all
-machines since the names of routines used in FORTRAN code cannot be easily
-redefined for different machines.
-
-The simplest way to achieve this end is to do explicitly give the modified
-FORTRAN name in the FCALLSCSUBn(...) and FCALLSCFUNn(...) declarations. e.g.
-
-FCALLSCSUB0(name,CFNAME,cfname)
-
-This allows FORTRAN to call the C routine 'name' as 'cfname'. Any name can of
-course be used for a given routine when it is called from FORTRAN, although
-this is discouraged due to the confusion it is sure to cause.  e.g. Bizarre,
-but valid and allowing C's 'call_back' routine to be called from FORTRAN as
-'abcd':
-
-FCALLSCSUB0(call_back,ABCD,abcd)
-
-
-cfortran.h also provides preprocessor directives for a systematic 'renaming' of
-the C routines when they are called from FORTRAN. This is done by redefining
-the fcallsc macro before the FCALLSCSUB/FUN/n declarations as follows:
-
-#undef  fcallsc
-#define fcallsc(UN,LN) preface_fcallsc(CF,cf,UN,LN)
-
-FCALLSCSUB0(hello,HELLO,hello)
-
-Will cause C's routine 'hello' to be known in FORTRAN as 'cfhello'. Similarly
-all subsequent FCALLSCSUB/FUN/n declarations will generate wrappers to allow
-FORTRAN to call C with the C routine's name prefaced by 'cf'. The following has
-the same effect, with subsequent FCALLSCSUB/FUN/n's appending the modifier to
-the original C routines name.
-
-#undef  fcallsc
-#define fcallsc(UN,LN) append_fcallsc(Y,y,UN,LN)
-
-FCALLSCSUB0(Xroutine,ROUTINE,routine)
-
-Hence, C's Xroutine is called from FORTRAN as:
-       CALL XROUTINEY()
-
-The original behavior of FCALLSCSUB/FUN/n, where FORTRAN routine names are left
-identical to those of C, is returned using:
-
-#undef  fcallsc
-#define fcallsc(UN,LN) orig_fcallsc(UN,LN)
-
-
-In C, when passing a C routine, i.e. its wrapper, as an argument to a FORTRAN
-routine, the FORTRAN name declared is used and the correct fcallsc must be in
-effect. E.g. Passing 'name' and 'routine' of the above examples to the FORTRAN
-routines, FT1 and FT2, respectively:

-
-iii) Using C to manipulate FORTRAN COMMON BLOCKS:
-     -------------------------------------------------------
-
-FORTRAN common blocks are set up with the following three constructs:
-
-1.
-#define Common_block_name COMMON_BLOCK(COMMON_BLOCK_NAME,common_block_name)
-
-Common_block_name is in UPPER CASE. 
-COMMON_BLOCK_NAME is in UPPER CASE.
-common_block_name is in lower case. 
-[Common_block_name actually follows the same 'rules' as Routine_name in Note 2.
- of II i).] This construct exists to ensure that C code accessing the common
-block is machine independent.
-
-2.
-COMMON_BLOCK_DEF(TYPEDEF_OF_STRUCT, Common_block_name);
-
-where 
-typedef { ... } TYPEDEF_OF_STRUCT;
-declares the structure which maps on to the common block. The #define of
-Common_block_name must come before the use of COMMON_BLOCK_DEF.
-
-3.
-In exactly one of the C source files, storage should be set aside for the
-common block with the definition: 
-
-TYPEDEF_OF_STRUCT  Common_block_name;
-
-The above definition may have to be omitted on some machines for a common block
-which is initialized by Fortran BLOCK DATA or is declared with a smaller size
-in the C routines than in the Fortran routines.
-
-The rules for common blocks are not well defined when linking/loading a mixture
-of C and Fortran, but the following information may help resolve problems.
-
-From the 2nd or ANSI ed. of K&R C, p.31, last paragraph:
-i)
- An external variable must be defined, exactly once, outside of any function;
- this sets aside storage for it.
-ii)
- The variable must also be declared in each function that wants to access it;
- ...
- The declaration ... may be implicit from context.
-
-In Fortran, every routine says 'common /bar/ foo',
-i.e. part ii) of the above, but there's no part i) requirement.
-cc/ld on some machines don't require i) either.
-Therefore, when handling Fortran, and sometimes C,
-the loader/linker must automagically set aside storage for common blocks.
-
-Some loaders, including at least one for the CRAY, turn off the
-'automagically set aside storage' capability for Fortran common blocks,
-if any C object declares that common block.
-Therefore, C code should define, i.e. set aside storage,
-for the the common block as shown above.
-
-e.g.
-C Fortran
-      common /fcb/  v,w,x
-      character *(13) v, w(4), x(3,2)
-
-/* C */
-typedef struct { char v[13],w[4][13],x[2][3][13]; } FCB_DEF;
-#define Fcb COMMON_BLOCK(FCB,fcb)
-COMMON_BLOCK_DEF(FCB_DEF,Fcb);
-FCB_DEF Fcb;      /* Definition, which sets aside storage for Fcb, */
-                  /* may appear in at most one C source file.      */
-
-
-C programs can place a string (or a multidimensional array of strings) into a
-FORTRAN common block using the following call:
-
-C2FCBSTR( CSTR, FSTR,DIMENSIONS);
-
-where:
-
-CSTR is a pointer to the first element of C's copy of the string (array). 
-     The C code must use a duplicate of, not the original, common block string,
-     because the FORTRAN common block does not allocate space for C strings'
-     terminating '\0'.
-
-FSTR is a pointer to the first element of the string (array) in the common
-     block.
-
-DIMENSIONS is the number of dimensions of string array. 
-     e.g. char a[10]      has DIMENSIONS=0.
-          char aa[10][17] has DIMENSIONS=1.
-          etc...
-
-C2FCBSTR will copy the string (array) from CSTR to FSTR, padding with blanks, 
-' ', the trailing characters as required. C2FCBSTR uses DIMENSIONS and FSTR to
-determine the lengths of the individual string elements and the total number of
-elements in the string array.
-
-Note that:
-- the number of string elements in CSTR and FSTR are identical.
-- for arrays of strings, the useful lengths of strings in CSTR and FSTR must be
-  the same. i.e. CSTR elements each have 1 extra character to accommodate the
-  terminating '\0'.
-- On most non-ANSI compilers, the DIMENSION argument cannot be prepended by any
-  blanks.
-
-
-FCB2CSTR( FSTR, CSTR,DIMENSIONS)
-
-is the inverse of C2FCBSTR, and shares the same arguments and caveats.
-FCB2CSTR copies each string element of FSTR to CSTR, minus FORTRAN strings'
-trailing blanks.
-
-
-cfortran.h USERS ARE STRONGLY URGED TO EXAMINE THE COMMON BLOCK EXAMPLES IN
-cfortest.c AND cfortex.f. The use of strings in common blocks is
-demonstrated, along with a suggested way for C to imitate FORTRAN EQUIVALENCE'd
-variables.
-
-
-              ===> USERS OF CFORTRAN.H NEED READ NO FURTHER <===
-
-
-III Some Musings
-----------------
-
-cfortran.h is simple enough to be used by the most basic of applications, i.e.
-making a single C/FORTRAN routine available to the FORTRAN/C programmers. Yet
-cfortran.h is powerful enough to easily make entire C/FORTRAN libraries
-available to FORTRAN/C programmers. 
-
-
-cfortran.h is the ideal tool for FORTRAN libraries which are being (re)written
-in C, but are to (continue to) support FORTRAN users. It allows the routines to
-be written in 'natural C', without having to consider the FORTRAN argument
-passing mechanisms of any machine. It also allows C code accessing these
-rewritten routines, to use the C entry point. Without cfortran.h, one risks the
-perverse practice of C code calling a C function using FORTRAN argument passing
-mechanisms!
-
-
-Perhaps the philosophy and mechanisms of cfortran.h could be used and extended
-to create other language bridges such as ADAFORTRAN, CPASCAL, COCCAM, etc.
-
-
-The code generation machinery inside cfortran.h, i.e. the global structure is
-quite good, being clean and workable as seen by its ability to meet the needs
-and constraints of many different compilers. Though the individual instructions
-of the A..., C..., T..., R... and K... tables deserve to be cleaned up.
-
-
-
-IV  Getting Serious with cfortran.h
------------------------------------
-
-cfortran.h is set up to be as simple as possible for the casual user. While
-this ease of use will always be present, 'hooks', i.e. preprocessor directives,
-are required in cfortran.h so that some of the following 'inefficiencies' can
-be eliminated if they cause difficulties:
-
-o cfortran.h contains a few small routines for string manipulation. These
-routines are declared static and are included and compiled in all source code
-which uses cfortran.h. Hooks should be provided in cfortran.h to create an
-object file of these routines, allowing cfortran.h to merely prototypes
-these routines in the application source code. This is the only 'problem' which
-afflicts both halves of cfortran.h. The remaining discussion refers to the C
-calls FORTRAN half only.
-
-o Similar to the above routines, cfortran.h generates code for a 'wrapper'
-routine for each FUNCTION exported from FORTRAN. Again cfortran.h needs
-preprocessor directives to create a single object file of these routines,
-and to merely prototype them in the applications.
-
-o Libraries often contain hundreds of routines. While the preprocessor makes
-quick work of generating the required interface code from cfortran.h and the
-application.h's, it may be convenient for very large stable libraries to have
-final_application.h's which already contain the interface code, i.e. these
-final_application.h's would not require cfortran.h. [The convenience can be
-imagined for the VAX VMS CC compiler which has a fixed amount of memory for
-preprocessor directives. Not requiring cfortran.h, with its hundreds of
-directives, could help prevent this compiler from choking on its internal
-limits quite so often.]
-
-With a similar goal in mind, cfortran.h defines 100's of preprocessor
-directives. There is always the potential that these will clash with other tags
-in the users code, so final_applications.h, which don't require cfortran.h,
-also provide the solution.
-
-In the same vein, routines with more than 14 arguments can not be interfaced by
-cfortran.h with compilers which limit C macros to 31 arguments. To resolve this
-difficulty, final_application.h's can be created on a compiler without this
-limitation.
-
-Therefore, new machinery is required to do:
-
-application.h + cfortran.h => final_application.h
-
-The following example may help clarify the means and ends:
-
-If the following definition of the HBOOK1 routine, the /*commented_out_part*/,
-is passed through the preprocessor [perhaps #undefing and #defining preprocessor
-constants if creating an application.h for compiler other than that of the
-preprocessor being used, e.g. cpp -Umips -DCRAY ... ] :
-
-#include "cfortran.h"
-PROTOCCALLSFSUB6(HBOOK1,hbook1,INT,STRING,INT,FLOAT,FLOAT,FLOAT)
-/*#define HBOOK1(ID,CHTITLE,NX,XMI,XMA,VMX)                 \*/
-     CCALLSFSUB6(HBOOK1,hbook1,INT,STRING,INT,FLOAT,FLOAT,FLOAT, \
-                 ID,CHTITLE,NX,XMI,XMA,VMX) 
-
-A function prototype is produced by the PROTOCCALLSFSUB6(...).
-Interface code is produced, based on the 'variables', 
-ID,CHTITLE,NX,XMI,XMA,VMX, which will correctly massage a HBOOK1 call.
-Therefore, adding the #define line:
-
-'prototype code'
-#define HBOOK1(ID,CHTITLE,NX,XMI,XMA,VMX)                 \
- 'interface code'(ID,CHTITLE,NX,XMI,XMA,VMX)
-
-which is placed into final_application.h.
-
-The only known limitation of the above method does not allow the 'variable'
-names to include B1,B2,...,B9,BA,BB,... 
-
-Obviously the machinery to automatically generate final_applications.h from
-cfortran.h and applications.h needs more than just some preprocessor
-directives, but a fairly simple unix shell script should be sufficient. Any
-takers?
-
-
-
-V Machine Dependencies of cfortran.h
-------------------------------------
-
-Porting cfortran.h applications, e.g. the hbook.h and cstring.c mentioned
-above, to other machines is trivial since they are machine independent. Porting
-cfortran.h requires a solid knowledge of the new machines C preprocessor, and
-its FORTRAN argument passing mechanisms. Logically cfortran.h exists as two
-halves, a "C CALLS FORTRAN" and a "FORTRAN CALLS C" utility. In some cases it
-may be perfectly reasonable to port only 'one half' of cfortran.h onto a new
-system.
-
-
-The lucky programmer porting cfortran.h to a new machine, must discover the
-FORTRAN argument passing mechanisms. A safe starting point is to assume that
-variables and arrays are simply passed by reference, but nothing is guaranteed.
-Strings, and n-dimensional arrays of strings are a different story. It is
-doubtful that any systems do it quite like VAX VMS does it, so that a UNIX or
-f2c versions may provide an easier starting point.
-
-
-cfortran.h uses and abuses the preprocessor's ## operator. Although the ##
-operator does not exist in many compilers, many kludges do. cfortran.h uses
-/**/ with no space allowed between the slashes, '/', and the macros or tags
-to be concatenated. e.g.
-#define concat(a,b) a/**/b   /* works*/
-main()
-{
-  concat(pri,ntf)("hello");           /* e.g. */
-}
-N.B. On some compilers without ##, /**/ may also not work. The author may be
-able to offer alternate kludges.
-
-
-
-VI Bugs in vendors C compilers and other curiosities
-----------------------------------------------------
-
-1. ULTRIX xxxxxx 4.3 1 RISC
-
-Condolences to long suffering ultrix users!
-DEC supplies a working C front end for alpha/OSF, but not for ultrix.
-
-From K&R ANSI C p. 231:
-   ultrix> cat cat.c
-   #define cat(x, y) x ## y
-   #define xcat(x,y) cat(x,y)
-   cat(cat(1,2),3)
-   xcat(xcat(1,2),3)
-   ultrix> cc -E cat.c
-   123                  <---- Should be: cat(1,2)3
-   123                  <---- Correct.
-   ultrix> 
-
-The problem for cfortran.h, preventing use of -std and -std1:
-   ultrix> cat c.c
-   #define cat(x, y) x ## y
-   #define xcat(x,y) cat(x,y)
-   #define AB(X) X+X
-   #define C(E,F,G)  cat(E,F)(G)
-   #define X(E,F,G) xcat(E,F)(G)
-   C(A,B,2)
-   X(A,B,2)
-   ultrix> cc -std1 -E c.c
-   2+2  
-   AB  (2)              <---- ?????????????
-   ultrix>
-   ultrix> cc -std0 -E c.c
-   2+2  
-   AB(2)                <---- ?????????????
-   ultrix>
-
-Due to further ultrix preprocessor problems,
-for all definitions of definitions with arguments,
-cfortran.h >= 3.0 includes the arguments and recommends the same,
-even though it is not required by ANSI C.
-e.g. Users are advised to do
-   #define fcallsc(UN,LN) orig_fcallsc(UN,LN)
-instead of
-   #define fcallsc        orig_fcallsc
-since ultrix fails to properly preprocess the latter example.
-CRAY used to (still does?) occasionally trip up on this problem.
-
-
-2. ConvexOS convex C210 11.0 convex
-
-In a program with a C main, output to LUN=6=* from Fortran goes into
-$pwd/fort.6 instead of stdout. Presumably, a magic incantation can be called
-from the C main in order to properly initialize the Fortran I/O.
-
-
-3. SunOS 5.3 Generic_101318-69 sun4m sparc
-
-The default data and code alignments produced by cc, gcc and f77 are compatible.
-If deviating from the defaults, consistent alignment options must be used
-across all objects compiled by cc and f77. [Does gcc provide such options?]
-
-
-4. SunOS 5.3 Generic_101318-69 sun4m sparc with cc: SC3.0.1 13 Jul 1994
-   or equivalently
-   ULTRIX 4.4 0 RISC using cc -oldc
-   are K&R C preprocessors that suffer from infinite loop macros, e.g.
-
-  zedy03> cat src.c
-  #include "cfortran.h"
-                            PROTOCCALLSFFUN1(INT,FREV,frev, INTV)
-  #define FREV(A1)               CCALLSFFUN1(    FREV,frev, INTV, A1)
-  /* To avoid the problem, deletete these ---^^^^--- spaces.    */
-  main() { static int a[] = {1,2}; FREV(a); return EXIT_SUCCESS; }
-
-  zedy03> cc -c -Xs -v -DMAX_PREPRO_ARGS=31 -D__CF__KnR src.c
-  "src.c", line 4: FREV: actuals too long
-  "src.c", line 4: FREV: actuals too long
-  .... 3427 more lines of the same message
-  "src.c", line 4: FREV: actuals too long
-  cc : Fatal error in /usr/ccs/lib/cpp
-  Segmentation fault (core dumped) 
-
-
-5. Older sun C compilers
-
-To link to f77 objects, older sun C compilers require the math.h macros:
-
-#define RETURNFLOAT(x)   { union {double _d; float _f; } _kluge; \
-                           _kluge._f = (x); return _kluge._d;   }
-#define ASSIGNFLOAT(x,y) { union {double _d; float _f; } _kluge; \
-                           _kluge._d = (y); x = _kluge._f;      }
-
-Unfortunately, in at least some copies of the sun math.h, the semi-colon
-for 'float _f;' is left out, leading to compiler warnings.
-
-The solution is to correct math.h, or to change cfortran.h to #define 
-RETURNFLOAT(x) and ASSIGNFLOAT(x,y) instead of including math.h.
-
-
-6. gcc version 2.6.3 and probably all other versions as well
-
-Unlike all other C compilers supported by cfortran.h,
-'gcc -traditional' promotes to double all functions returning float
-as demonstrated bu the following example.
-
-/* m.c */
-#include <stdio.h>
-int main() { FLOAT_FUNCTION d(); float f; f = d(); printf("%f\n",f); return 0; }
-
-/* d.c */
-float d() { return -123.124; }
-
-burow[29] gcc -c -traditional d.c
-burow[30] gcc -DFLOAT_FUNCTION=float m.c d.o && a.out
-0.000000
-burow[31] gcc -DFLOAT_FUNCTION=double m.c d.o && a.out
--123.124001
-burow[32]
-
-Thus, 'gcc -traditional' is not supported by cfortran.h.
-Support would require the same RETURNFLOAT, etc. macro machinery
-present in old sun math.h, before sun gave up the same promotion.
-
-
-7. CRAY
-
-At least some versions of the t3e and t3d C preprocessor are broken
-in the fashion described below.
-At least some versions of the t90 C preprocessor do not have this problem.
-
-On the CRAY, all Fortran names are converted to uppercase.
-Generally the uppercase name is also used for the macro interface
-created by cfortran.h.
-
-For example, in the following interface,
-EASY is both the name of the macro in the original C code
-and EASY is the name of the resulting function to be called.
-
-#define EASY(A,B)      CCALLSFSUB2(EASY,easy, PINT, INTV, A, B)
-
-The fact that a macro called EASY() expands to a function called EASY()
-is not a problem for a working C preprocessor.
-From Kernighan and Ritchie, 2nd edition, p.230:
-
-    In both kinds of macro, the replacement token sequence is repeatedly
-  rescanned for more identifiers. However, once a given identifier has been
-  replaced in a given expansion, it is not replaced if it turns up again during
-  rescanning; instead it is left unchanged.
-
-Unfortunately, some CRAY preprocessors are broken and don't obey the above rule.
-A work-around is for the user to NOT use the uppercase name
-of the name of the macro interface provided by cfortran.h. For example:
-
-#define Easy(A,B)      CCALLSFSUB2(EASY,easy, PINT, INTV, A, B)
-
-Luckily, the above work-around is not required since the following
-work-around within cfortran.h also circumvents the bug:
-
-   /* (UN), not UN, is required in order to get around  CRAY preprocessor bug.*/
-   #define CFC_(UN,LN)            (UN)      /* Uppercase FORTRAN symbols.     */
-
-Aside: The Visual C++ compiler is happy with UN, but barfs on (UN),
-       so either (UN) causes nonstandard C/C++ or Visual C++ is broken.
-

-Acknowledgements:
-- CERN very generously sponsored a week in 1994 for me to work on cfortran.h.
-- M.L.Luvisetto (Istituto Nazionale Fisica Nucleare - Centro Nazionale
-  Analisi Fotogrammi, Bologna, Italy) provided all the support for the port to
-  the CRAY. Marisa's encouragement and enthusiasm was also much appreciated.
-- J.Bunn (CERN) supported the port to PowerStation Fortran with Visual C++.
-- Paul Schenk (UC Riverside, CERN PPE/OPAL) in June 1993 extended cfortran.h 2.7
-  to have C++ call Fortran. This was the starting point for full C++ in 3.4.
-- Glenn P.Davis of University Corp. for Atmospheric Research (UCAR) / Unidata
-  supported the NEC SX-4 port and helped understand the CRAY.
-- Tony Goelz of Absoft Corporation ported cfortran.h to Absoft.
-- Though cfortran.h has been created in my 'copious' free time, I thank 
-  NSERC for their generous support of my grad. student and postdoc years.
-- Univ.Toronto, DESY, CERN and others have provided time on their computers.

-I have no time right now to read through licenses.
-IIRC, library GPL is fairly unrestrictive, so I'll choose that. So.....

-You may consider this e-mail as a notice that as an alternative to any
-other cfortran licenses,
-I hereby relase all versions and all parts of cfortran under the

-   Modifications:
-      Oct 1997: Changed symbol name extname to appendus (PDW/HSTX)
-                (Conflicted with a common variable name in FTOOLS)
-      Nov 1997: If g77Fortran defined, also define f2cFortran (PDW/HSTX)
-      Feb 1998: Let VMS see the NUM_ELEMS code. Lets programs treat
-                single strings as vectors with single elements
-      Nov 1999: If macintoxh defined, also define f2cfortran (for Mac OS-X)
-      Apr 2000: If WIN32 defined, also define PowerStationFortran and
-                VISUAL_CPLUSPLUS (Visual C++)
-      Jun 2000: If __GNUC__ and linux defined, also define f2cFortran
-                (linux/gcc environment detection)
-      Apr 2002: If __CYGWIN__ is defined, also define f2cFortran
-      Nov 2002: If __APPLE__ defined, also define f2cfortran (for Mac OS-X)
-
-      Nov 2003: If __INTEL_COMPILER or INTEL_COMPILER defined, also define
-                f2cFortran (KMCCARTY)
-      Dec 2005: If f2cFortran is defined, enforce REAL functions in FORTRAN
-                returning "double" in C.  This was one of the items on
-		Burkhard's TODO list. (KMCCARTY)
-      Dec 2005: Modifications to support 8-byte integers. (MR)
-		USE AT YOUR OWN RISK!
-      Feb 2006  Added logic to typedef the symbol 'LONGLONG' to an appropriate
-                intrinsic 8-byte integer datatype  (WDP)
-      Apr 2006: Modifications to support gfortran (and g77 with -fno-f2c flag)
-                since by default it returns "float" for FORTRAN REAL function.
-                (KMCCARTY)
-      May 2008: Revert commenting out of "extern" in COMMON_BLOCK_DEF macro.
-		Add braces around do-nothing ";" in 3 empty while blocks to
-		get rid of compiler warnings.  Thanks to ROOT developers
-		Jacek Holeczek and Rene Brun for these suggestions. (KMCCARTY)
-      Dec 2008  Added typedef for LONGLONG to support Borland compiler (WDP)

-/*  Old CFARGT14 -> CFARGT14FS as seen below, for Absoft cross-compile yields:
-      SunOS> cc -c -Xa -DAbsoftUNIXFortran c.c
-      "c.c", line 406: warning: argument mismatch
-    Haven't checked if this is ANSI C or a SunOS bug. SunOS -Xs works ok.
-    Behavior is most clearly seen in example:
-      #define A 1 , 2
-      #define  C(X,Y,Z) x=X. y=Y. z=Z.
-      #define  D(X,Y,Z) C(X,Y,Z)
-      D(x,A,z)
-    Output from preprocessor is: x = x . y = 1 . z = 2 .

-                   Log of Changes Made to CFITSIO
-
-Version 3.31 - 18 July 2012
-
-   - enhanced the CFITSIO column filtering syntax to allow the comma, in addition
-     to the semi-colon, to be used to separate clauses, for example:
-     [col X,Y;Z = max(X,Y)].  This was done because users are not allowed to
-     enter the semi-colon character in the on-line Hera data processing
-     system due to computer security concerns.
-
-   - enhanced the CFITSIO extended filename syntax to allow specifying image
-     compression parameters (e.g. '[compress Rice]') when opening an existing
-     FITS file with write access.  The specified compression parameters will
-     be used by default if more images are appended to the existing file.
-
-   - modified drvrfile.c to do additional file secrity checks when CFITSIO
-     is running within the HEASARC's Hera software system.  In this case
-     CFITSIO will not allow FITS files to be created outside of the user's
-     individual Hera data directory area.
-
-   - fixed an issue in fpack and funpack on Windows machines, caused by
-     the fact that the 'rename' function behaves differently on Windows
-     in that it does not clobber an existing file, as it does on Unix
-     platforms.
-
-   - fixed bug in the way byte-swapping was being performed when writing 
-     integer*8 null values to an image or binary table column.  
-
-   - added the missing macro definition for fffree to fitsio.h.
-
-   - modified the low level table read and write functions in getcol*.c and 
-     putcol*.c to remove the 32-bit limitation on the number of elements. 
-     These routines now support reading and writing more than 2**31 elements
-     at one time. Thanks to Keh-Cheng Chu (Stanford U.) for the patch.
-
-   - modified Makefile.in so that the shared libcfitsio.so is linked against 
-     pthreads and libm.
-
-Version 3.30 - 11 April 2012
-
-  Enhancements
-
-   - Added new routine called fits_is_reentrant which returns 1 or 0 depending on
-     whether or not CFITSIO was compiled with the -D_REENTRANT directive.  This can
-     be used to determine if it is safe to use CFITSIO in multi-threaded programs.
-
-   - Implimented much faster byte-swapping algorithms in swapproc.c based on code
-     provided by Julian Taylor at ESO, Garching.  These routines significantly 
-     improve the FITS image read and write speed (by more than a factor of 2 in 
-     some cases) on little-endian machines (e.g., Linux and Microsoft Windows and
-     Macs running on x86 CPUs) where byte-swapping is required when reading and 
-     writing data in FITS files.  This has no effect on big-endian machines 
-     (e.g. Motorola CPUs and some IBM systems).  Even faster byte-swapping
-     performance can be achieved in some cases by invoking the new "--enable-sse2" 
-     or "--enable-ssse3" configure options when building CFITSIO on machines that
-     have CPUs and compilers that support the SSE2 and SSSE3 machine instructions.
-
-   - added additional support for implicit data type conversion in cases where
-     the floating point image has been losslessly compressed with gzip.  The
-     pixels in these compressed images can now be read back as arrays of short, 
-     int, and long integers as well as single and double precision floating-point.
-
-   - modified fitsio2.h and f77_wrap.h to recognize IBM System z mainframes by
-     testing if __s390x__ or __s390__ is defined.
-
-   - small change to ffgcrd in getkey.c so that it supports reading a blank
-     keyword (e.g., a keyword whose name simply contains 8 space chracters).
-
-   Bug Fixes
-
-   - fixed a bug in imcomp_decompress_tile that caused the tile-compressed image 
-     to be uncompressed incorrectly (even though the tile-compressed image itself
-     was written correctly) under the following specific conditions:
-      - the original FITS image has a "float" datatype (R*4) 
-      - one or more of the image tiles cannot be compressed using the standard
-        quantization method  and instead are losslessly compressed with gzip
-      - the pixels in these tiles are not all equal to zero (this bug does
-        affect tiles where all the pixels are equal to zero)
-      - the program that is reading the compressed image uses CFITSIO's
-        "implicit datatype conversion" feature to read the "float" image
-        back into an array of "double" pixel values.
-      If all these conditions are met, then the returned pixel values in the
-      affected image tiles will be garbage, with values often ranging 
-      up to 10**34.  Note that this bug does not affect the fpack/funpack
-      programs, because funpack does not use CFITSIO's implicit datatype
-      conversion feature when uncompressing the image.
-
-Version 3.29 - 2 December 2011
-
-  Enhancements
-
-   - modified Makefile.in to allow configure to override the lib and include
-     destination directories.
-		   
-   - added (or restored actually) support for tile compression of 1-byte integer 
-     images in imcomp_compress_tile.  Support for that data type was overlooked
-     during recent updates to this routine.
-
-   - modified the fits_get_token command-line parsing routine to perform more
-     rigorous checks to determine if the token can be interpreted as a number 
-     or not.
-
-   - made small modification to fpack.c to not allow the -i2f option (convert
-     image from integer to floating point) with the "-g -q 0" option (do lossless 
-     gzip compression).  It is more efficient to simply use the -g option alone.
-
-   - made modifications to fitsio.h and drvrfile.c to support reading and
-     writing large FITS files (> 2.1 GB) when building CFITSIO using 
-     Microsoft Visual C++ on Windows platforms.
-
-   - added new WCS routine (ffgicsa) which returns the WCS keyword values
-     for a particular WCS version ('A' - 'Z').
-
-   Bug Fixes
-
-   - fixed a problem with multi-threaded apps that open/close FITS files
-     simultaneously by putting mutex locks around the call to
-     fits_already_open and in fits_clear_Fptr.
-
-   - fixed a bug when using the 'regfilter' function to select a subset of the
-     rows in a FITS table that have coordinates that lie within a specified
-     spatial region on the sky.  This bug only affects the rarely used panda
-     (and epanda and bpanda) region shapes in which the region is defined by
-     the intersection of an annulus  and a pie-shaped wedge.  The previous code
-     (starting with version 3.181 of CFITSIO where support for the panda region
-     was first introduced) only worked correctly if the 2 angles that define
-     the wedge have values between -180 and +180.  If not, then fewer rows than
-     expected may have been selected from the table.
-
-   - fixed the extended filename parser so that when creating a histogram by
-     binning 2 table columns, if a keyword or column name is given as the
-     weighting factor,  then the output histrogram image will have a floating
-     point datatype, not the default integer datatype as is the case when no
-     weigth is specified (e.g. with a filename like 
-     "myfile.fits[bin x,y; weight_column]"
-
-   - added fix to the code in imcompress.c to work around a problem with
-     dereferencing the value of a pointer, in cases where the address of 
-     that pointer has not been defined (e.g., the nulval variable).
-
-    - modified the byte shuffling algorithm in fits_shuffle_8bytes to work
-     around a strange bug in the proprietary SunStudioExpress C compiler
-     under OpenSolaris.
-
-   - removed spurious messages on the CFITSIO error stack when opening a
-     FITS file with FTP (in drvrnet.c);
-
-Version 3.28 - 12 May 2011
-
-   - added an enhancement to the tiled-image compression method when compressing
-     floating-point image using the standard (lossy) quantization method.  In 
-     cases where an image tile cannot be quantized,  The floating-point pixel values
-     will be losslessly compressed with gzip before writing them to the tile-
-     compressed file.  Previously, the uncompressed pixel values would have
-     been written to the file, which obviously requires more disk space. 
-
-   - made significant internal changes to the structure of the tile compression
-     and uncompression routines in imcompress.c to make them more modular and
-     easier to maintain.
-
-   - modified configure.in and configure to force it to build a Universal 
-     binary on Mac OS X.
-
-   - modified the ffiter function in putcol.c to properly clean up allocated
-     memory if an error occurs.
-     
-   - in quantize.c, when searching for the min and max values in a float array,
-     initialize the max value to -FLT_MAX instead of FLT_MIN (and similarly
-     for double array). 
-
-Version 3.27 - 3 March 2011
-
-  Enhancements
-
-    - added new routines fits_read_str and fits_delete_str which read or
-      delete, respectively, a header keyword record that contains a specified 
-      character string.
-
-    - added a new routine called fits_free_memory which frees the memory
-      that fits_read_key_longstr allocated for the long string keyword value.
-
-    - enhanced the ffmkky routine in fitscore.c to not put a space before the
-      equals sign when writing long string-valued keywords using the ESO
-      HIERARCH keyword convension, if that extra character is needed to
-      fit the length of the keyword name + value string within the 80-character
-      FITS keyword record.
-
-    - made small change to fits_translate_keyword to support translation of
-      blank keywords (where the name = 8 blank chracters)
-
-    - modified fpack so that it uses the minimum of the 2nd, 3rd, and 5th order
-      MAD noise values when quantizing and compressing a floating point image.
-      This is more conservative than just using the 3rd order MAD value alone.
-
-    - added new routine imcomp_copy_prime2img to imcompress.c that is used by
-      funpack to copy any keywords that may have been added to the primary
-      array of the compressed image file (a null image) back into the header of 
-      the uncompressed image.
-
-    - enhanced the fits_quantize_float and fits_quantize_double routines in
-      quantize.c to also compress the tile if it is completely filled with
-      null values.  Previously, this type of tile would have been written 
-      to the output compressed image without any compression.
-
-    - enhanced imcomp_decompress_tile to support implicit datatype conversion
-      when reading a losslessly compressed (with gzip) real*4 image into an
-      array of real*8 values.  
-
-    - in imcompress.c, removed possible attempt to free memory that had not 
-      been allocated.
-
-
-Version 3.26 - 30 December 2010
-
-  Enhancements
-
-   - defined 2 new macros in fitsio.h:  
-       #define CFITSIO_MAJOR 3
-       #define CFITSIO_MINOR 26
-     These may be used within other macros to detect the CFITSIO
-     version number at compile time.
-     
-   - modified group.c to initialize the output URL to a null string in 
-     fits_url2relurl.  Also added more robust tests to see if 2 file
-     pointers point to the same file.
-
-   - enhanced the template keyword parsing code in grparser.c to support
-     the 'D' exponent character in the ASCII representation of floating
-     point keyword values (as in TVAL = 1.23D03).  Previously, the parser
-     would have writen this keyword with a string value (TVAL = '1.23D03').
-
-   - modified the low-level routines that write a keyword record to a FITS 
-     header so that they silently replace any illegal characters (ASCII 
-     values less than 32 or greater than 126) with an ASCII space character.
-     Previously, these routines would have returned with an error when
-     encountering these illegal characters in the keyword record (most commonly 
-     tab, carriage return, and line feed characters).
-
-   - made substantial internal changes to imcompress.c in preparation for
-     possible future support for compression methods for FITS tables analogous
-     to the tiled image compression method.
-
-   - replaced all the source code in CFITSIO that was distributed under the
-     GNU General Public License with freely available code.  In particular,
-     the  gzip file compression and uncompression code was replaced by the
-     zlib compression library.  Thus, beginning with this version 3.26 of CFITSIO,
-     other software applications may freely use CFITSIO without necessarily
-     incurring any GNU licensing requirement.  See the License.txt file for
-     the CFITSIO licensing requirements.
-
-   - added support for using cfitsio in different 'locales' which use a
-     comma, not a period, as the decimal point character in ASCII 
-     representation of a floating point number (e.g., France).  This
-     affects how floating point keyword values and floating point numbers
-     in ASCII tables are read and written with the 'printf' and 'strtod'
-     functions.
-
-   - added a new utility routine called fits_copy_rows/ffcprw that copies
-     a specified range of rows from one table to another.
-
-   - enhanced the test for illegal ASCII characters in a header (fftrec) to
-     print out the name of the offending character (e.g TAB or Line Feed) as
-     well as the Hex value of the chracter.
-     
-   - modified ffgtbc (in fitscore.c) to support nonstandard vector variable
-     length array columns in binary tables (e.g. with TFORMn = 2000PE(500)').
-     
-   - modified the configure file to add "-lm" when linking CFITSIO on
-     Solaris machines.
-     
-   - added new routine, fits_get_inttype, to parse an integer keyword value
-     string and return the minimum integer datatype (TBYTE, TSHORT, TLONG, 
-     TLONGLONG) required to store the integer value.
-
-   - added new routine, fits_convert_hdr2str, which is similar to fits_hdr2str
-     except that if the input HDU is a tile compressed image (stored 
-     in a binary table) then it will first convert that header back to 
-     that of a normal uncompressed FITS image before concatenating the header
-     keyword records.
-
-   - modified the file template reading routine (ngp_line_from_file in 
-     grparser.c) so that it ignores any carriage return characters (\r)
-     in the line, that might be present, e.g. if the file was created on a 
-     Windows machine that uses \r\n as end of line characters.
-
-   - modified the ffoptplt routine in cfileio.c to check if the PCOUNT
-     keyword in the template file has a non-zero value, and if so, resets
-     it to zero in the newly created file.
-
-   Bug Fixes
-   
-   - fixed a bug when uncompressing floating-point images that contain Nan
-     values on some 64-bit platforms.
-     
-   - fixed a bug when updating the value of the CRPIXn world coordinate 
-     system keywords when extracting a subimage from larger FITS image, using the
-     extended CFITSIO syntax (e.g.  myimage[1:500:2, 1:500:2]).  This bug only 
-     affects casee where the pixel increment value is not equal to 1, and caused
-     the coordinate grid to be shifted by between 0.25 pixels (in the case of
-     a pixel increment of 2) and 0.5 pixels (for large pixel increment values).
-
-   - fixed a potential string buffer overflow error in the ffmkls routine
-     that modifies the value and comment strings in a keyword that uses
-     the HEASARC long string keyword convention. 
-
-   - fixed a bug in imcompress.c that could cause programs to abort on 64-bit 
-     machines when using gzip to tile-compress images.  Changed the declaration
-     of clen in imcomp_compress_tile from int to size_t.
-
-Version 3.25 - 9 June 2010
-
-   - fixed bug that was introduced in version 3.13 that broke the ability
-     to reverse an image section along the y-axis with an image section
-     specifier like this: myimage.fits[*,-*].  This bug caused the output
-     image to be filled with zeros.
-
-   - fixed typo in the definition of the ftgprh Fortran wrapper routine
-     in f77_wrap3.c.
-
-   - modified the cfitsio.pc.in configuration file to make the lib path
-     a variable instead of hard coding the path.   The provides more
-     flexibility for projects such as suse and fedora when building CFITSIO.
-
-   - fixed bug in imcomp_compress_tile in imcompress.c which caused
-     null pixel values to be written incorrectly in the rare case where 
-     the floating-point tile of pixels could not be quantized into integers.
-
-   - modified imcompress.c to add a new specialized routine to uncompress
-     an input image and then write it to a output image on a tile by tile basis.
-     This appears to be faster than the old method of uncompressing the
-     whole image into memory before writing it out.  It also supports
-     large images with more than 2**31 pixels.
-
-   - made trivial changes to 2 statements in drvrfile.c to suppress 
-     nuisance compiler warnings.
-
-   - some compilers define CLOCKS_PER_SEC as a double instead of an integer,
-     so added an explicted integer type conversion to 2 statements in
-     imcompress.c that used this macro.
-     
-   - removed debugging printf statements in drvrnet.c (15 July)
-
-Version 3.24 - 26 January 2010
-
-   - modified fits_translate_keywords so that it silently ignores any
-     illegal ASCII characters in the value or comment fields of the input
-     FITS file. Otherwise, fpack would abort without compressing input
-     files that contained this minor violation of the FITS rules.
-
-   - added support for Super H cpu in fitsio2.h
-   
-   - updated funpack to correctly handle the -S option, and to use a
-     more robust algorithm for creating temporary output files.
-   
-   - modified the imcomp_compress_tile routine to support the NOCOMPRESS
-     debugging option for real*4 images.
-
-Version 3.23 - 7 January 2010
-
-   - reduced the default value for the floating point image quantization
-     parameter (q) from 16 to 4.  This parameter is used when tile compressing
-     floating point images.  This change will increase the average compression
-     ratio for floating point images from about 4.6 to about 6.5 without losing 
-     any significant information in the image.
-     
-   - enhanced the template keyword parsing routine to reject a header
-     template string that only contains a sequence of dashes.
-
-   - enhanced the ASCII region file reading routine to allow tabs as well
-     as spaces between fields in the file.
-
-   - got rid of bogus error message when calling fits_update_key_longstr
-
-   - Made the error message more explicit when CFITSIO tries to write
-     to a GZIP compressed file.  Instead of just stating "cannot write
-     to a READONLY file", it will say "cannot write to a GZIP compressed
-     file".
-
-Version 3.22 - 28 October 2009
-
-   - added an option (in imcompress.c) to losslessly compress floating
-     point images, rather than using the default integer scaling method.
-     This option is almost never useful in practice for astronomical 
-     images (because the amount of compression is so poor), but it has 
-     been added for test comparison purposes.
-
-   - enhanced the dithering option when quantizing and compressing
-     floating point images so that a random dithering starting point
-     is used, so that the same dithering pattern does not get used for
-     every image.
-
-   - modified the architecture setup section of fitsio2.h to support the
-     64-core 8x8-architecture Tile64 platform (thanks to Ken Mighell, NOAO)
-
-   Fixes
-
-   - fixed a problem that was introduced in version 3.13 of CFITSIO
-     in cases where a program writes it own END keyword to the header
-     instead of letting CFITSIO do it, as is strongly recommended.  In
-     one case this caused CFITSIO to rewrite the END keyword and any
-     blank fill keywords in the header many times, causing a 
-     noticeable slow-down in the FITS file writing speed.
-
-Version 3.21 - 24 September 2009
-
-   - fixed bug in cfileio.c  that caused CFITSIO to crash with a bus error
-     on Mac OS X if CFITSIO was compiled with multi-threaded support (with
-     the  --enable-reentrant configure option). The Mac requires an
-     additional thread initialization step that is not required on Linux
-     machines.  Even with this fix, occasional bus errors have been seen on
-     some Mac platforms, The bus errors are seen when running the
-     thread_test.c program.  The bus errors are very intermittent, and occur
-     less than about 1% of the time, on the affected platforms. 
-     These bus errors have not been seen on Linux platforms. 
-
-   - fixed invalid C comment delimiter ("//*" should have been "/*")
-     in imcompress.c.
-
-   - Increased the CFITSIO version number string length
-     in fpackutil.c, to fix problem on some platforms when running
-     fpack -V or funpack -V.   Also modified the output format of the
-     fpack -L command.
-
-Version 3.20 - 31 August 2009
-
-   - modified configure.in and configure so that it will build the Fortran
-     interface routines by default, even if no Fortran compiler is found
-     in the user's path. Building the interface routines may be disabled 
-     by specifying FC="none".  This was done at the request of users who
-     obtained CFITSIO from some other standard linux distributions, where
-     CFITSIO was apparently built in an environment that had no Fortran 
-     compiler and hence did not build the Fortran wrappers.
-
-   - modified ffchdu (close HDU) so that it calls the routine to update
-     the maximum length of variable length table columns in the TFORM
-     values in all cases  where the values may have changed.  Previously
-     it would not update the values if a value was already specified in
-     the TFORM value.
-
-   - added 2 new string manipulation functions to the CFITSIO parser 
-     (contributed by Craig Markwardt): strmid extracts a substring
-     from a string, and strstr searches for a substring within a string.
-
-   - removed the code in quantize.c that treated "floating-point integer" 
-     images as a special case (it would just do a datatype conversion from
-     float to int, and not otherwise quantize the pixel values).  This 
-     caused complications with the new subtractive dithering feature.
-
-   - enhanced the code for converting floating point images to quantized
-     scaled integer prior to tile-compressing them, to apply a random
-     subtractive dithering, which improves the photometric accuracy
-     of the compressed images.
-   
-   - added new internal routine, iraf_delete_file, for use by fpack to
-     delete a pair of IRAF format header and pixel files.
-
-   - small change in cfileio.c in the way it recognizes an IRAF format
-     .imh file.  Instead of just requiring that the filename contain the
-     ".imh" string, that string must occur at the end of the file name.
-
-   - fixed bug in the code that is used when tile-compressing real*4 FITS 
-     images, which quantizes the floating point pixel values into
-     integer levels.  The bug would only appear in the fairly rare
-     circumstance of tile compressing a floating point image that contains
-     null pixels (NaNs) and only when using the lossy Hcompress algorithm
-     (with the s parameter not equal to 1).  This could cause underflow of
-     low valued pixels, causing them to appear as very large pixel values
-     (e.g., > 10**30)  in the compressed image
-
-   - changed the "if defined" blocks in fitsio.h, fitsio2.h and f77_wrap.h
-     to correctly set the length of long variables on sparc64 machines.
-     Patch contributed by Matthew Truch (U. Penn).
-
-   - modified the HTTP file access code in drvrnet.c to support basic
-     HTTP authentication, where the user supplies a user name and
-     password.  The CFITSIO filename format in this case is:
-     "http://username:password@hostname/..."
-     Thanks to Jochen Liske (ESO) for the suggestion and the code.
-
-Version 3.181 (BETA) - 12 May 2009
-
-   - modified region.c and region.h to add support for additional
-     types of region shapes that are supported by ds9: panda, epanda,
-     and bpanda.
-
-   - fixed compiler error when using the new _REENTRANT flag, having to 
-     do with the an attempted static definition of Fitsio_Lock in 
-     several source files, after declaring it to be non-static in fitsio2.h.
-    
-Version 3.18 (BETA) - 10 April 2009
-
-   - Made extensive changes to make CFITSIO thread safe.  Previously,
-     all opened FITS files shared a common pool of memory to store
-     the most recently read or written FITS records in the files.
-     In a multi-threaded environment different threads could 
-     simultaneously read or write to this common area causing
-     unpredictable results. This was changed so that every opened
-     FITS file has its own private memory area for buffering the
-     file. Most of the changes were in buffers.c, fitsio.h, and
-     fitsio2.h. Additional changes were made to cfileio.c, mainly
-     to put locks around small sections of code when setting up the
-     low-level drivers to read or write the FITS file.  Also, locks
-     were needed around the GZIP compression and uncompression code
-     in compress.c.,  the error message stack access routine in
-     fitscore.c, the encode and decode routines in fits_hcompress.c
-     and  fits_hdecompress.c, in ricecomp.c,  and  the table row
-     selection and table calculator functions. Also, removed the
-     'static' declaration of the local variables in pliocomp.c
-     which did not appeared to be required and prevented the
-     routines from being thread safe.
-
-     As a consequence of having a separate memory buffer for every
-     FITS file (by default, about 115 kB per file), CFITSIO may now
-     allocate more memory than previously when an application
-     program opens multiple FITS files at once.  The read and write
-     speed may also be slightly faster, since the buffers are not
-     shared between files.
-
-   - Added new families of Fortran wrapper routines to read and
-     write values to large tables that have more than 2**31 rows. 
-     The arguments that define the first row and first element to
-     read or write must be I*8 integers, not ordinary I*4
-     integers.  The names of these new routines have 'LL' appended
-     to them, so for example, ftgcvb becomes ftgcvbll.
-
-   Fixes
-   
-   - Corrected an obscure bug in imcompress.c that would have incorrectly 
-     written the null values only in the rare case of writing a signed 
-     byte array that is then tile compressed using the Hcompress or PLIO
-     algorithm.
-
-Version 3.14 - 18 March 2009
-
-  Enhancements
-
-   - modified the tiled-image compression and uncompression code to
-     support compressing unsigned 16-bit integer images with PLIO.
-     FITS unsigned integer arrays are offset by -32768, but the PLIO
-     algorithm does not work with negative integer values.  In this
-     case, an offset of 32768 is added to the array before compression,
-     and then subtracted again when reading the compressed array.
-     IMPORTANT NOTE:  This change is not backward compatible, so
-     these PLIO compressed unsigned 16-bit integer images will not be
-     read correctly by previous versions of CFITSIO; the pixel values
-     will have an offset of +32768.
-
-   - minor changes to the fpack utility to print out more complete
-     version information with the -V option, and format the report
-     produced by the -T option more compactly.
-
-  Fixes
-  
-   - Modified imcomp_compress_image (which is called by fpack) so that
-     it will preserve any null values (NaNs) if the input image has
-     a floating point datatype (BITPIX = -32 or -64).  Null values in
-     integer datatype images are handled correctly.
-
-   - Modified imcomp_copy_comp2img so that it does not copy the
-     ZBLANK keyword, if present, from the compressed image header
-     when uncompressing the image.
-     
-   - Fixed typo in the Fortran wrapper macro for the ftexist function.
-
-Version 3.13 -  5 January 2009
-
-  Enhancements
-
-   - updated the typedef of LONGLONG in fitsio.h and cfortran.h to
-     support the Borland compiler which uses the  __int64 data type.
-     
-   - added new feature to the extended filename syntax so that when
-     performing a filtering operation on specified HDU, if you add
-     a '#' character after the name or number of the HDU, then ONLY
-     that HDU (and the primary array if the HDU is a table) will be
-     copied into the filtered version of the file in memory.  Otherwise,
-     by default CFITSIO copies all the HDUs from the input file into
-     memory.
-     
-   - when specifying a section, if the specified number of dimensions
-     is less than the number of dimensions in the image, then CFITSIO
-     will use the entire dimension, as if a '*' had been specified.
-     Thus [1:100] is equivalent to [1:100,*] when specifying a section
-     of 2 dimensional image.
-
-   - modified fits_copy_image_section to read/write the section 1 row
-     at a time, instead of the whole section, to reduce memory usage.
-
-   - added new stream:// drivers for reading/writing to stdin/stdout.
-     This driver is somewhat fragile, but for simple FITS read and
-     write operations this driver streams the FITS file on stdin
-     or stdout without first copying the entire file in memory, as is
-     done when specifying the file name as "-".
-   
-   - slight modification to ffcopy to make sure that the END keyword
-     is correctly written before copying the data.  This is required
-     by the new stream driver.
-     
-   - modified ffgcprll, so that when writing data to an HDU, it first
-     checks that the END keyword has been written to the correct place.
-     This is required by the new stream driver.
-
-  Fixes
-   
-   - fixed bug in ffgcls2 when reading an ASCII string column in binary
-     tables in cases where the width of the column is greater than 2880 
-     characters and when reading more than 1 row at a time.  Similar 
-     change was made to ffpcls to fix same problem with writing to 
-     columns wider than 2880 characters.
-     
-   - updated the source files listed in makepc.bat so that it can be
-     used to build CFITSIO with the Borland C++ compiler.
-     
-   - fixed overflow error in ffiblk that could cause writing to Large Files
-     (> 2.1 GB) to fail with an error status.
-      
-   - fixed a bug in the spatial region code (region.c) with the annulus 
-     region.   This bug only affected specialized applications which
-     directly use the internal region structure; it does not affect
-     any CFITSIO functions directly.
-
-   - fixed memory corruption bug in region.c that was triggered if the
-     region file contained a large number of excluded regions.
-
-   - got rid of a harmless error message that would appear if filtering
-     a FITS table with a GTI file that has zero rows. (eval_f.c)
-
-   - modified fits_read_rgnfile so that it removes the error messages
-     from the error stack if it is unable to open the region file as
-     a FITS file. (region.c)
-     
-Version 3.12 - 8 October 2008
-
-   - modified the histogramming code so that the first pixel in the binned
-     array is chosen as the reference pixel by default, if no other
-     value is previously defined.
-
-   - modified ffitab and ffibin to allow a null pointer to the 
-     EXTNAME string, when inserting a table with no name.
-
-Version 3.11 - 19 September 2008
-
-   - optimized the code when tile compressing real*4 images (which get
-     scaled to integers).  This produced a modest speed increase.  For 
-     best performance, one must specify the absolute q quantization 
-     parameter, rather than relative to the noise in the tile (which
-     is expensive to compute).
-
-   - modified the FITS region file reading code to check for NaN values,
-     which signify the end of the array of points in a polygon region.
-
-   - removed the test for LONGSIZE == 64 from fitsio.h, since it may 
-     not be defined.
-
-   - modified imcompress.c to support unconventional floating point FITS 
-     images that also have BSCALE and BZERO keywords.  The compressed
-     floating point images are linearly scaled twice in this case.
-
-Version 3.10 - 20 August 2008
-
-   - fixed a number of cases, mainly dealing with long input file names
-     (> 1024 char), where unsafe usage of strcat and strcpy could have caused
-     buffer overflows.  These buffer overflows could cause the application
-     to crash, and at least theoretically, could be exploited by a
-     malicious user to execute arbitrary code.  There are no known instances
-     of this type of malicious attack on CFITSIO applications, and the
-     likelihood of such an attack seems remote.  None the less, it would
-     be prudent for CFITSIO users to upgrade to this new version to guard
-     against this possibility.
-
-   - modified some of the routines to define input character string
-     parameters as "const char *" rather than just "char *" to eliminate
-     some compiler warnings when the calling routine passes a constant
-     string to the CFITSIO routine.  Most of the changes were to the
-     keyword name argument in the many routines that read or write keywords.
-
-   - fixed bug when tile-compressing a FITS image which caused all the 
-     completely blank keywords in the input header to be deleted from 
-     the output compressed image.  Also added a feature to preserve any
-     empty FITS blocks in the header (reserved space for future keywords)
-     when compressing or uncompressing an image.
-
-   - fixed small bug in the way the default tile size is set in imcompress.c.
-     (Fix sent in by Paul Price).
-
-   - added support for reading FITS format region files (in addition
-     to the ASCII format that was previously supported).  Thanks to
-     Keith Arnaud for modifying region.c to do this.
-
-Version 3.09 - 12 June 2008
-
-   - fixed bug in the calculator function, parse_data, that evaluates 
-     expressions then selecting rows or modifying values in table columns.
-     This bug only appeared in unusual circumstances
-     where the calculated value has a null value (= TNULLn).  The bug
-     could cause elements to not be flagged as having a null value, or
-     in rare cases could cause valid elements to be flagged as null. This
-     only appears to have affected 64-bit platforms (where size(long) = 8).
-   
-   - fixed typo in imcomp_decompress_tile: call to fffi2r8 should have 
-     been to fffi4r8.
-     
-   - in the imcopy_copy_comp2img routine, moved the call to 
-     fits_translate_keywords outside of the 'if' statement.  This could 
-     affect reading compressed images that did not have a EXTNAME keyword
-     in the header.
-     
-   - fixed imcomp_compress_tile in imcompress.c to properly support
-     writing unsigned integers, in place, to tile compressed images.
-
-   - modified fits_read_compressed_img so that if the calling routine
-     specifies nullval = 0, then it will not check for null-valued
-     pixels in the compressed FITS image.  This mimics the same
-     behavior when reading normal uncompressed FITS images.
-
-Version 3.08 - 15 April 2008 
-
-   - fixed backwards compatibility issue when uncompressing a Rice
-     compressed image that was created with previous versions of 
-     CFITSIO (this late fix was added on May 18).
-
-   - small change to cfortran.h to add "extern" to the common block 
-     definition.  This was done for compatibility with the version
-     of cfortran.h that is distributed by the debian project.
-   
-   - relaxed the requirement that a string valued keyword must have a
-     closing quote character.  If the quote is missing, CFITSIO will silently
-     append a quote at the end of the keyword record.  This change was made
-     because otherwise it is very difficult to correct the keyword
-     because CFITSIO would exit with an error before making the fix.
-   
-   - added a new BYTEPIX compression parameter when tile-compressing 
-     images with the Rice algorithm.
-
-   - cached the NAXIS and NAXISn keyword values in the fitsio structure
-     for efficiency, to eliminate duplicates reads of these keywords.
-   
-   - added variants of the Rice compression and uncompression routines to
-     support short int images (in addition to the routines that support int).
-
-   - moved the definition of LONGLONG_MIN and LONGLONG_MAX from fitsio2.h
-     to fitsio.h, to make it accessible to application programs.
-
-   - make efficiency improvements to fitscore.c, to avoid needless searches
-     through the entire header when reading the required keywords that must
-     be near the beginning of the header.
-     
-   - made several improvements to getcol.c to optimize reading of compressed
-     and uncompressed images.
-
-   - changed the compression level in the gzip code from 6 to 1.  In most
-     cases this will provide nearly the same amount of compression, but is
-     significantly faster in some cases.
-	   
-   - added new "helper routines' to imcompress.c to allow applications to
-     specified the "quantize level" and Hcompress scaling and smoothing 
-     parameters
-
-   - modified the extended filename syntax to support the "quantize level"
-     and Hcompress scaling and smoothing parameters.  The parser in 
-     cfileio.c was extensively modified.
-
-   - extensive changes to quantize.c:
-       - replace the "nbits" parameter with "quantize level"
-       - the quantize level is now relative to the RMS noise in the image
-       - the HCOMPRESS scale factor is now relative to the RMS noise
-       - added routines to calculate RMS noise in image 
-      (these changes require a change to the main file structure in fitsio.h)
-
-   - initialize errno = 0 before the call to strtol in ffext, in case errno
-     has previously been set by an unrelated error condition.
-
-   - added the corresponding long name for the ffgkyjj routine to longnam.h.		   
-
-   - changed imcomp_copy_comp2img (in imcompress.c) to not require the
-     presence of the EXTNAME keyword in the input compressed image header.
-
-   - modified imcompress.c to only write the UNCOMPRESSED_DATA column
-     in tile-compressed images if it is actually needed.  This eliminates
-     the need to subsequently delete the column if it is not used 
-     (which is almost always the case).
-
-   - found that it is necessary to seek to the EOF of a file after 
-     truncating the size of the file, to reestablish a definite
-     current location in the file.  The required small changes to 3
-     routines: file_truncate (to seek to EOF) and fftrun (to set io_pos) 
-     and the truncation routine in drvrmem.c.
-
-   - improved the efficiency when compressing integer images with
-     gzip.  Previously, the image was always represented using integer*4
-     pixels, which were then compressed.  Now, if the range of pixel
-     values can be represented with integer*2 pixels or integer*1 pixels, 
-     then that is used.  This change is backward compatible with any 
-     compressed images that used the previous method.
-
-   - changed the default tiling pattern when using Hcompress from 
-     large squares (200 to 600 pixels wide) to 16 rows of the image.
-     This generally requires less memory, compresses faster, and is more
-     consistent with the default row by row tiling when using the other
-     compression methods.
-
-   - modified imcomp_init_table in imcompress.c to enforce a restriction
-     when using the Hcompress algorithm that the 1st 2 dimensions of sll
-     image tiles must be at least 4 pixels long.  Hcompress becomes very
-     inefficient for smaller dimensions, and does not work at all with
-     1D images.
-     
-   - fixed bug in the Hcompress compression algorithm that could affect
-     compression of I*4 images, using non-square compression tiles
-     (in the encode64 routine).
-
-Version 3.07 - 6 December 2007  (internal release)
-
-   - fixed bug with the PLIO image compression routine which silently
-     produced a corrupted compressed image if the uncompressed image pixels
-     were not all in the range 0 to 2**24.  (fixed in November)
-     
-   - fixed several 'for' loops in imcompress.c which were exceeding the
-     bounds of an array by 1.  (fixed in November)
-
-   - fixed a possible, but unlikely, memory overflow issue in iraffits.c.
-   
-   - added a clarification to the cfortran.doc file that cfortran.h
-     may be used and distributed under the terms of the GNU Library
-     General Public License.
-   
-   - fixed bug in the fits_modify_vector_len routine when modifying
-     the vector length of a 'X' bit column.
-	   
-Version 3.06 - 27 August 2007  
-
-   - modified the imcopy.c utility program (to tile-compress images)
-     so that it writes the default EXTNAME = 'COMPRESSED_IMAGE'
-     keyword in the compressed images, to preserve the behavior of
-     earlier versions of imcopy.
-
-   - modified the angsep function in the FITS calculator (in eval.y)
-     to use haversines, instead of the 'law of cosines', to provide
-     more precision at small angles (< 0.1 arcsec).
-
-Version 3.05 -  July 2007 (internal release only)
-
-   - extensive changes to imcompress.c to fully support implicit data
-     type conversion when reading and writing arrays of data to FITS
-     images, where the data type of the array is not the same as the
-     data type of the FITS image.  This includes support for null pixels,
-     and data scaling via the BSCALE and BZERO keywords.
-
-   - rewrote the fits_read_tbl_coord routine in wcssub.c, that gets the 
-     standard set of WCS keywords appropriate to a pair of columns in a
-     table, to better support the full set of officially approved WCS keywords.  
-     
-   - made significant changes to histo.c, which creates an image by binning
-     columns of a table, to better translate the WCS keywords in the table
-     header into the WCS keywords that are appropriate for an image HDU.
-
-   - modified imcompress.c so that when pixels are written to a 
-     tile-compressed image, the appropriate BSCALE and BZERO values of
-     that image are applied.  This fixes a bug in which writing to
-     an unsigned integer datatype image (with BZERO = 32768) was not
-     done correctly.
-     
-Version 3.04 - 3 April 2007
-
-   - The various table calculator routines (fits_select_rows, etc.) implicitly
-     assumed that the input table has not been modified immediately prior to
-     the call.   To cover cases where the table has been modified a call to 
-     ffrdef has been added to ffprs.  IN UNUSUAL CASES THIS CHANGE COULD 
-     CAUSE CFITSIO TO BEHAVE DIFFERENTLY THAN IN PREVIOUS VERSIONS.  For
-     example, opening a FITS table with this column-editing virtual file
-     expression:
-         myfile.fits[3][col A==X; B = sqrt(X)]
-     no longer works, because the X column does not exist when the 
-     sqrt expression is evaluated.  The correct expression in this case is
-         myfile.fits[3][col A==X; B = sqrt(A)]
-     
-   - modified putkey.c to support USHORT_IMG when calling fits_create_img
-     to create a signed byte datatype image.
-     
-   - enhanced the column histogramming function to propagate any TCn_k and
-     TPn_k keywords in the table header to the corresponding CDi_j and PCi_j 
-     keywords in the image header.
-     
-   - enhanced the random, randomn, and randomp functions in the lexical
-     parser to take a vector column name argument to specify the length
-     of the vector of random numbers that should be generated (provided by
-     Craig Markwardt, GSFC)
-
-   - enhanced the ffmcrd routine (to modify an existing header card) to
-     support long string keywords so that any CONTINUE keywords associated
-     with the previous keyword will be deleted.
-
-   - modified the ffgtbp routine to recognize the TDIMn keyword for 
-     ASCII string columns in a binary table.  The first dimension is
-     taken to be the size of a unit string.   (The TFORMn = 'rAw'
-     syntax may also be used to specify the unit string size).
-     
-   - in fits_img_decompress, the fits_get_img_param function was called
-     with an invalid dimension size, which caused a fatal error on at
-     least 1 platform.
-
-   - in ffopentest, set the status value before returning in case of error.
-   
-   - in the drvrnet.c file, the string terminators needed to be changed
-     from "\n" to "\r\n" to support the strict interpretation of the
-     http and ftp standard that is enforced by some newer web servers.
-
-Version 3.03 - 11 December 2006
-
-  New Routine
-  
-  - fits_write_hdu writes the current HDU to a FILE stream (e.g. stdout).
-  
-  Changes
-  
-  - modified the region parsing code to support region files where the
-    keyword "physical" is on a separate line preceding the region shape
-    token. (However, "physical" coordinates are not fully supported, and
-    are treated identically to "image" coordinates).
-    
-  - enhanced the iterator routines to support calculations on 64-bit
-    integer columns and images.  Currently, the values are cast to
-    double precision when doing the calculations, which can cause a
-    loss of precision for integer values greater than about 2**52.
-
-  - added support for accessing FITS files on the computational grid.
-    Giuliano Taffoni and Andrea Barisani, at INAF, University of Trieste,
-    Italy, implemented the necessary I/O driver routines in drvrgsiftp.c.
-
-  - modified the tiled image compression/uncompression routines to 
-    preserve/restore the original CHECKSUM and DATASUM keywords if they
-    exist. (saved as ZHECKSUM and ZDATASUM in the compressed image)
-  
-  - split fits_select_image_section into 2 routines: a higher level routine
-    that creates the output file and copies other HDUs from the input file
-    to the output file, and a lower level routine that extracts the image
-    section from the input image into an output image HDU.
-    
-  - Improved the error messages that get generated if one tries to 
-    use the lexical parser to perform calculations on variable-length
-    array columns.
-
-  - added "#define MACHINE NATIVE" in fitsio2.h for all machines where
-    BYTESWAPPED == FALSE.  This may improve the file writing performance
-    by eliminating the need to allocate a temporary buffer in some cases.
-
-  - modified the configure.in and configure script to fix problems with
-    testing if network services are available, which affects the definition
-    of the HAVE_NET_SERVICES flag.
-
-  - added explicit type casting to all malloc statements, and deleted 
-    declarations of unreferenced variables in the image compression code 
-    to suppress compiler warnings.
-    
-  - fixed incorrect logic in fitsio2.h in the way it determined if numerical
-    values are byteswapped or not on MIPS and ARM architectures.
-
-  - added __BORLANDC__ to the list of environments in fitsio.h that don't
-    use %lld in printf for longlong integers
-    
-  - added "#if defined(unix)" around "#include <usistd.h>" statements in
-    several C source files, to make them compatible with Windows.
-    
-
-Version 3.02 - 18 Sept 2006
-
-  - applied the security patch to the gzip code, available at
-    http://security.FreeBSD.org/patches/SA-06:21/gzip.patch
-    The insufficient bounds checks in buffer use can cause gzip to crash,
-    and may permit the execution of arbitrary code.  The NULL pointer
-    deference can cause gzip to crash.  The infinite loop can cause a
-    Denial-of-Service situation where gzip uses all available CPU time.
-
-  - added HCOMPRESS as one of the compression algorithm options in the
-    tiled image compression code.  (code provided by Richard White (STScI))
-    Made other improvements to preserve the exact header structure in the 
-    compressed image file so that the compressed-and-then-uncompressed FITS 
-    image will be as identical as possible to the original FITS image file.  
-
-  New Routines		   
-
-  - the following new routines were added to support reading and writing
-    non-standard extension types:
-     fits_write_exthdr - write required keywords for a conforming extension
-     fits_write_ext - write data to the extension
-     fits_read_ext  - read data from the extension
-     
-  - added new routines to compute the RMS noise in the background pixels
-    of an image: fits_rms_float and fits_rms_short  (take an input
-    array of floats or shorts, respectively).
-
-  Fixes
-
-  - added the missing 64-bit integer case to set of "if (datatype)" 
-    statements in the routine that returns information about a 
-    particular column (ffgbclll).
-    
-  - fixed a parsing error in ffexts in cases where an extension number
-    is followed by a semi-colon and then the column and row number of an
-    array in a binary table.  Also removed an extraneous HISTORY keyword
-    that was being written when specifying an input image in a table cel.
-  
-  - modified the routine that reads a table column returning a string
-    value (ffgcls) so that if the displayed numerical value is too
-    wide to fit in the specified length string, then it will return
-    a string of "*" characters instead of the number string.
-
-  - small change to fitsio.h to support a particular Fortran and C
-    compiler combination on a SGI Altix system
-    
-  - added a test in the gunzip code to prevent seg. fault when trying
-    to uncompress a corrupted file (at least in some cases).
-
-  - fixed a rarely-occurring bug in the routine that copies a table
-    cell into an image; had to call the ffflsh call a few lines earlier.
-
-Version 3.01 - (in FTOOLS 6.1 release)
-
-  - modified fits_copy_image2cell to correctly copy all the appropriate
-    header keywords when copying an image into a table cell
-
-  - in eval.y, explicitly included the code for the lgamma function 
-    instead of assuming it is available in a system library (e.g., the
-    lgamma function is currently not included in MS Visual++ libraries)
-
-  - modified the logic in fits_pixel_filter so that the default data
-    type of the output image will be promoted to at least BITPIX = -32
-    (a single precision floating point) if the expression that is being
-    evaluated resolves to a floating point result.  If the expression 
-    resolves to an integer result, the output image will have the same
-    BITPIX as the input image.
-
-  - in fits_copy_cell2image, added 5 more WCS keywords to the list of
-    keywords related to other columns that should be deleted in the
-    output image header.
-
-  - disabled code in cfileio.c that would write HISTORY keywords to the
-    output file in fits_copy_image2cell and cell2image, because some tasks
-    would not want these extraneous HISTORY keywords.
-
-  - added 2 new random number functions to the CFITSIO parser
-    RANDOMN() - produces a normal deviate (mean=0, stddev=1)
-    RANDOMP(X) - produces a Poisson deviate for an expected # of counts X
-
-  - in f77_wrap.h, removed the restriction that "g77Fortran" must be 
-    defined on 64-bit Itanium machines before assuming that 
-    sizeof(long) = 8.  It appears that "long"s are always
-    8 bytes long on this machine, regardless of what compilers are used.
-
-  - added test in fitsio.h so that LONGLONG cannot be multiply defined
-  
-  - modified longnam.h so that both "fits_write_nulrows" and 
-    "fits_write_nullrows"  get replace by the string "ffprwu".  This
-    fixes a documentation error regarding the long name of this
-    routine.
-
-   Bug fixes
-
-  - fixed a potential null character string dereferencing error in the
-    the ffphtb and ffphbn routines that write the FITS table keywords.
-    This concerned the optional TUNITn keywords.
-
-  - fixed a few issues in fits_copy_cell2image and fits_copy_image2cell
-    related to converting some WCS keyword between the image extension
-    form and the table cell form of the keyword. (cfileio.c)
-
-  - fixed bug in fits_translate_keyword (fitscore.c) that, e.g.,  caused 
-   'EQUINOX' to be translated to EQUINOXA' if the pattern is 'EQUINOXa'
-
-  - fixed 2 bugs that could affect 'tile compressed' floating point
-    images that contain NaN pixels (null pixels).  First, the
-    ZBLANK keyword was not being written, and second, an integer
-    overflow could occur when computing the BZERO offset in the
-    compressed array.  (quantize.c and imcompress.c)
-
-Version 3.006 - 20 February 2006  -(first full release of v3)
-
-  - enhanced the 'col' extended filename syntax to support keyword name
-    expressions like
-       [col error=sqrt(rate); #TUNIT# = 'counts/s'], 
-    in which the trailing '#' will be replaced by the column number
-    of the most recently referenced column.
-    
-  - fixed bug in the parse_data iterator work function that caused it
-    to fail to return a value of -1 in cases where only a selected
-    set of rows were to be processed. (affected Fv)
-
-  - added code to fitsio.h and cfortran.h to typedef LONGLONG to
-    the appropriate 8-byte integer data type.  Most compilers now
-    support the 'long long' data type, but older MS Visual C++
-    compilers used '__int64' instead.
-
-  - made several small changes based on testing by Martin Reinecke:
-    o in  eval.y, change 'int undef' to 'long undef'
-    o in getcold.c and getcole.c, fixed a couple format conversion 
-      specifiers when displaying the value of long long variables.
-    o in fitsio.h, modified the definition of USE_LL_SUFFIX in the
-      case of Athon64 machines.
-    o in fitsio2.h,  defined BYTESWAPPED in the case of SGI machines.
-    o in group.c, added 'include unistd.h' to get rid of compiler warning.
-      
-Version 3.005 - 20 December 2005  (beta)
-
-  - cfortran.h has been enhanced to support 64-bit integer parameters
-    when calling C routines from Fortran.  This modification was kindly 
-    provided by Martin Reinecke (MPE, Garching).  
-    
-  - Many new Fortran wrapper routines have been added to support reading
-    and writing 64-bit integer values in FITS files.  These new routines
-    are documented in the updated version of the 'FITSIO User's Guide' 
-    for Fortran programmers.
-
-  - fixed a problem in the fits_get_keyclass routine that caused it
-    to not recognize the special COMMENT keywords at the beginning
-    of most FITS files that defines the FITS format.
-
-  - added a new check to the ffifile routine that parses the 
-    input extended file name, to distinguish between a FITS extension
-    name that begins with 'pix', and a pixel filtering operator that 
-    begins with the 'pix' keyword.
-
-  - small change to the WCSLIB interface routine, fits_read_wcstab, to
-    be more permissive in allowing the TDIMn keyword to be omitted for
-    degenerate coordinate array.
-
-Version 3.004 - 16 September 2005 (3rd public beta release)
-
-  - a major enhancement to the CFITSIO virtual file parser was provided
-    by Robert Wiegand (GSFC).  One can now specify filtering operations
-    that will be applied on the fly to the pixel values in a FITS image. 
-    For example [pix sqrt(X)] will create a virtual FITS image where the
-    pixel values are the square root of the input image pixels.
-
-  - modified region.c so that it interprets the position angles of regions
-    in a SAO style region file in the same way as DS9.  In particular, if
-    the region parameters are given in WCS units, then the position angle
-    should be relative to the WCS coordinates of the image (increasing CCW
-    from West) instead of relative to the X/Y pixel coordinate system.
-    This only affects rotated images (e.g. with non-zero CROTA2 keyword)
-    with elliptical or rectangular regions.
-
-  - cleaned up fitsio.h and fitsio2.h to make the definition of LONGLONG
-    and BYTESWAPPED and MACHINE more logical.
-    
-  - removed HAVE_LONGLONG everywhere since it is no longer needed (the 
-    compiler now must have an 8-byte integer datatype to build CFITSIO).
-    
-  - added support for the 64-bit IBM AIX platform
-
-  - modified eval.y so that the circle, ellipse, box, and near functions
-    can operate on vectors as well as scalars.  This allows region filtering
-    on images that are stored in a vector cell in a binary table. 
-    (provided by Craig Markwardt, GSFC)
-
-  New Routines
-  
-  - added new fits_read_wcstab routine that serves as an interface to
-    Mark Calabretta's wcslib library for reading WCS information when
-    the -TAB table lookup convention is used in the FITS file.
-
-  - added new fits_write_nullrows routine, which writes null values into
-    every column of a specified range of rows in a FITS table.
-
-  - added the fits_translate_keyword and fits_translate_keywords utility
-    routines for converting the names of keywords when moving columns and
-    images around.
-    
-  - added fits_copy_cell2image and fits_copy_image2cell routines for
-    copying an image extension (or primary array) to or from a cell
-    in a binary table vector column. 
-  
-  Bug fixes
-  
-  - fixed a memory leak in eval.y;  was fixed by changing a call to malloc
-    to cmalloc instead.
-
-  - changed the definition of several global variables at the beginning
-    of buffers.c to make them 'static' and thus invisible to applications
-    programs.
-
-  - in fits_copy_image_cell, added a call to flush the internal buffers
-    before reading from the file, in case any records had been modified.
-
-Version 3.003 - 28 July 2005 - 2nd public beta release (used in HEASOFT)
-
-  Enhancements
-  
-  - enhanced the string column reading routing fits_get_col_str to 
-    support cases where the user enters a null pointer (rather than
-    a null string) as the nulval parameter.
-
-  - modified the low level ffread and ffwrite routines that physically
-    read and write data from the FITS file so that they write the name
-    of the file to the CFITSIO error stack if an error occurs.
-
-  - changed the definition of fits_open_file into a macro that will test
-    that the version of the fitsio.h include file that was used to 
-    build the CFITSIO library is the same version as included when
-    compiling the application program.
-
-  - made a simple modification to region.c to support regions files
-    of type "linear", for compatibility with ds9 and fv.
-    
-  - modified the internal ffgpr routine (and renamed it ffgprll) so
-    that it returns the TNULL value as a LONGLONG parameter instead
-    of 'long'.
-    
-  - in fits_get_col_display_width, added support for TFORM = 'k'
-  
-  - modified fitsio.h, fitsio2.h, and f77_wrap.h to add test for (_SX)
-    to identify NEC SX supercomputers.
-
-  - modified eval_f.c to treat table columns of TULONG  (unsigned long)
-    as a double.  Also added support for TLONGLONG (8-byte integers) as
-    a double, which is only a temporary fix, since doubles only have about
-    52 bits of precision.
-
-  - changed the 'blank' parameter in the internal ffgphd function to
-    to type LONGLONG to support integer*8 FITS images.
-
-  - when reading the TNULL keyword value, now use ffc2jj instead of
-    ffc2ii, to support integer*8 values.
-
-  Bug fixes
-
-  - fixed a significant bug when writing character strings to a variable
-    length array column of a binary table. This bug would result in some
-    unused space in the variable length heap, making the heap somewhat
-    larger than necessary.  This in itself is usually a minor issue, since
-    the FITS files are perfectly valid, and other software should have
-    no problems reading back the characters strings. In some cases, however,
-    this problem could cause the program that is writing the table
-    to exit with a status = 108 disk read error.
-
-  - modified the standalone imcopy.c utility program to fix a memory allocation
-    bug when running on 64-bit platforms where sizeof(long) = 8 bytes.
-
-  - added an immediate 'return' statement to ffgtcl if the input status >0, 
-    to prevent a segfault on some platforms.
-
-Version 3.002 - 15 April 2005 - first public beta release
-
-  - in drvrfile.c, if it fails to open the file for some reason, then
-    it should reset file_outfile to a null string, to avoid errors on
-    a subsequent call to open a file.
- 
-  - updated fits_get_keyclass to recognize most of the WCS keywords
-    defined in the WCS Papers I and II.
-
-Version 3.001 - 15 March 2005  - released with HEASOFT 6.0
-
-  - numerous minor changes to the code to get rid of compiler warning
-    messages, mainly dealing with numerical data type casting and the
-    subsequent possible loss of precision in the result.
-
-Version 3.000 - 1 March 2005 (internal beta release)
-
-  Enhancements:
-
-   - Made major changes to many of the CFITSIO routines to more generally 
-     support Large Files (> 2.1 GB).  These changes are intended to 
-     be 100% backward compatible with software that used the previous 
-     versions of CFITSIO.  The datatype of many of the integer parameters 
-     in the CFITSIO functions has been changed from 'long' to 'LONGLONG', 
-     which is typedef'ed to be equivalent to an 8-byte integer datatype on 
-     each platform. With these changes, CFITSIO supports the following:
-        - integer FITS keywords with absolute values > 2**31
-        - FITS files with total sizes > 2**31 bytes
-	- FITS tables in which the number of rows, the row width, or
-	  the size of the heap is > 2**31 bytes
-	- FITS images with dimensions > 2**31 bytes (support is still 
-	  somewhat limited, with full support to be added later).
-
-   - added another lexical parser function (thanks to Craig Markwardt,
-     GSFC): angsep computes the angular separation between 2 positions
-     on the celestial sphere.
-  
-   - modified the image subset extraction code (e.g., when specifying
-     an image subregion when opening the file, such as 
-     'myimage.fits[21:40, 81:90]') so that in addition to
-     updating the values of the primary WCS keywords CRPIXk, CDELTi, and
-     CDj_i in the extracted/binned image, it also looks for and updates 
-     any secondary WCS keywords (e.g., 'CRPIX1P').
-
-   - made cosmetic change to group.c, so that when a group table is
-     copied, any extra columns will be appended after the last existing
-     column, instead of being inserted before the last column.
-     
-   - modified the routines that read tile compressed images to support
-     NULL as the input value for the 'anynul' parameter (meaning the
-     calling program does not want the value of 'anynul' returned to it).
-      
-   - when constructing or parsing a year/month/day character string,
-     (e.g, when writing the DATE keyword) the routines now rigorously
-     verify that the input day value is valid for the given month 
-     (including leap years).
-
-   - added some checks in cfileio.c to detect if some vital parameters
-     that are stored in memory have been corrupted.  This can occur if
-     a user's program writes to areas of memory that it did not allocate.
-
-   - added the wcsutil_alternate.c source code file which contains
-     non-working stubs for the 2 Classic AIPS world coordinate
-     conversion routines that are distributed under the GNU General
-     Public License.  Users who are unwilling or unable to distribute
-     their software under the General Public License may use this 
-     alternate source file which has no GPL restrictions, instead
-     of wcsutil.c.  This will have no effect on programs that use 
-     CFITSIO as long as they do not call the fits_pix_to_world/ffwldp
-     or fits_world_to_pix/ffxypx routines.
-     
-   Bug Fixes
-   
-   - in ffdtdm (which parses the TDIMn keyword value), the check for
-     consistency between the length of the array defined by TDIMn and
-     the size of the TFORMn repeat value, is now not performed for variable
-     length array columns (which always have repeat = 1).
-
-   - fixed byteswapping problem when writing null values to non-standard
-     long integer FITS images with BITPIX = 64 and FITS table columns with
-     TFORMn = 'K'.
-
-   - fixed buffer overflow problem in fits_parse_template/ffgthd that
-     occurred only if the input template keyword value string was much
-     longer than can fit in an 80-char header record.
-     
-Version 2.510 - 2 December 2004
-
-  New Routines:
-  
-   - added fits_open_diskfile and fits_create_diskfile routines that simply
-     open or create a FITS file with a specified name.  CFITSIO does not
-     try to parse the name using the extended filename syntax.
-     
-   - 2 new C functions, CFITS2Unit and CUnit2FITS, were added to convert
-     between the C fitsfile pointer value and the Fortran unit number.
-     These functions may be useful in mixed language C and Fortran programs.   
-   
-  Enhancements:
-  
-   - added the ability to recognize and open a compressed FITS file
-     (compressed with gzip or unix compress) on the stdin standard input
-     stream.
-  
-   - Craig Markwardt (GSFC) provided 2 more lexical parser functions:
-     accum(x) and seqdiff(x) that compute the cumulative sum and the
-     sequential difference of the values of x.
-  
-   - modified putcole.c and putcold.c so that when writing arrays of
-     pixels to the FITS image or column that contain null values, and
-     there are also numerical overflows when converting some of the
-     non-null values to the FITS values, CFITSIO will now ignore the
-     overflow error until after all the data have been written. Previously,
-     in some circumstances CFITSIO would have simply stopped writing any
-     data after the first overflow error.     
-      
-   - modified fitsio2.h to try to eliminate compiler warning messages
-     on some platforms about the use of 'long long' constants when 
-     defining the value of LONGLONG_MAX (whether to use L or LL
-     suffix).
-
-   - modified region.c to support 'physical' regions in addition to
-     'image', 'fk4', etc.
-
-   - modified ffiurl (input filename parsing routine) to increase the 
-     maximum allowed extension number that can be specified from 9999 
-     to 99999 (e.g. 'myfile.fits+99999')
-
-  Bug Fixes:
-  
-   - added check to fits_create_template to force it to start with
-     the primary array in the template file, in case an extension
-     number was specified as part of the template FITS file name.
-      
-Version 2.500 - 28 & 30 July 2004
-
-  New Routine:  
-  
-   - fits_file_exists tests whether the specified input file, or a 
-     compressed version of the file, exists on disk.
-
-  Enhancements:
-
-   - modified the way CFITSIO reads and writes data in COMPLEX ('C') and
-     DBLCOMPLEX 'M' columns.  Now, in all cases, when referring to the
-     number of elements in the vector, or the value of the offset to a 
-     particular element within the vector, CFITSIO considers each pair of
-     numbers (the imaginary and real parts) as a single element instead of
-     treating each single number as an element. In particular, this changes
-     the behavior of fits_write_col_null when writing to complex columns.  
-     It also changes the length of the 'nullarray' vector in the
-     fits_read_colnull routine;  it is now only 1/2 as long as before.
-     Each element of the nullarray is set = 1 if either the real or 
-     imaginary parts of the corresponding complex value have a null
-     value.(this change was added to version 2.500 on 30 July).
-
-   - Craig Markwardt, at GSFC, provided a number of significant enhancements
-     to the CFITSIO lexical parser that is used to evaluate expressions:
-     
-       - the parser now can operate on bit columns ('X') in a similar
-         way as for other numeric columns (e.g., 'B' or 'I' columns)
-	 
-       - range checking has been implemented, so that the following 
-         conditions return a Null value, rather than returning an error:
-	 divide by zero, sqrt(negative),  arccos(>1), arcsin(>1),
-	 log(negative), log10(negative)
-	 
-       - new vector functions:  MEDIAN, AVERAGE, STDDEV, and 
-         NVALID (returns the number of non-null values in the vector)
-
-       - all the new functions (and SUM, MIN and MAX) ignore null values
-       
-   - modified the iterator to support variable-length array columns
-
-   - modified configure to support AIX systems that have flock in a non-
-     standard location.
-     
-   - modified configure to remove the -D_FILE_OFFSET_BITS flag when running
-     on Mac Darwin systems.  This caused conflicts with the Fortran
-     wrappers, and should only be needed in any case when using CFITSIO
-     to read/write FITS files greater than 2.1 GB in size.
-
-   - modified fitsio2.h to support compilers that define LONG_LONG_MAX.
-
-   - modified ffrsim (resize an existing image) so that it supports changing
-     the datatype to an unsigned integer image using the USHORT_IMG and
-     ULONG_IMG definitions.
-
-   - modified the disk file driver (drvrfile.c) so that if an output
-     file is specified when opening an ordinary file (e.g. with the syntax
-     'myfile.fits(outputfile.fits)' then it will make a copy of the file,
-     close the original file and open the copy.  Previously, the
-     specified output file would be ignored unless the file was compressed.
-
-   - modified f77_wrap.h and f77_wrap3.c to support the Fortran wrappers
-     on 64-bit AMD Opteron machines
-
-  Bug fixes:
-
-   - made small change to ffsrow in eval_f.c to avoid potential array 
-     bounds overflow.
-     
-   - made small change to group.c to fix problem where an 'int' was
-     incorrectly being cast to a 'long'.
-
-   - corrected a memory allocation error in the new fits_hdr2str routine
-     that was added in version 2.48
-
-   - The on-the-fly row-selection filtering would fail with a segfault
-     if the length of a table row (NAXIS1 value) was greater than
-     500000 bytes.  A small change to eval_f.c was required to fix this.
-
-Version 2.490 - 11 February 2004
-
-  Bug fixes:
-
-  - fixed a bug that was introduced in the previous release, which caused
-    the CFITSIO parser to no longer move to a named extension when opening
-    a FITS file, e.g., when opening myfile.fit[events] CFITSIO would just
-    open the primary array instead of moving to the EVENTS extension.
-
-  - new group.c file from the INTEGRAL Science Data Center.  It fixes
-    a problem when you attach a child to a parent and they are both
-    is the same file, but, that parent contains groups in other files.
-    In certain cases the attach would not happen because it seemed that
-    the new child was already in the parent group.
-
-  - fixed bug in fits_calculator_rng when performing a calculation
-    on a range of rows in a table, so that it does not reset the
-    value in all the other rows that are not in the range = 0.
-
-  - modified fits_write_chksum so that it updates the TFORMn 
-    keywords for any variable length vector table columns BEFORE 
-    calculating the CHECKSUM values.  Otherwise the CHECKSUM
-    value is invalidated when the HDU is subsequently closed.
-
-Version 2.480 - 28 January 2004
-
-  New Routines:
-
-  - fits_get_img_equivtype - just like fits_get_img_type, except in
-    the case of scaled integer images, it returns the 'equivalent' 
-    data type that is necessary to store the scaled data values.  
-
-  - fits_hdr2str copies all the header keywords in the current HDU
-    into a single long character string.  This is a convenient method
-    of passing the header information to other subroutines.
-    The user may exclude any specified keywords from the list.
-
-  Enhancements:
-
-  - modified the filename parser so that it accepts extension
-    names that begin with digits, as in 'myfile.fits[123TEST]'.
-    In this case CFITSIO will try to open the extension with
-    EXTNAME = '123TEST' instead of trying to move to the 123rd
-    extension in the file.
-
-  - the template keyword parser now preserves the comments on the
-    the mandatory FITS keywords if present, otherwise a standard
-    default comment is provided.
-
-  - modified the ftp driver file (drvrnet.c) to overcome a timeout
-    or hangup problem caused by some firewall software at the user's
-    end (Thanks to Bruce O'Neel for this fix).
-
-  - modified iraffits.c to incorporate Doug Mink's latest changes to
-    his wcstools library routines.  The biggest change is that now
-    the actual image dimensions, rather than the physically stored
-    dimensions, are used when converting an IRAF file to FITS.
-
-  Bug fixes:
-
-  - when writing to ASCII FITS tables, the 'elemnum' parameter was
-    supposed to be ignored if it did not have the default value of 1.
-    In some cases however setting elemnum to a value other than 1 
-    could cause the wrong number of rows to be produced in the output
-    table.
-
-  - If a cfitsio calculator expression was imported from a text file
-    (e.g. using the extended filename syntax 'file.fits[col @file.calc]')
-    and if any individual lines in that text file were greater than 
-    255 characters long, then a space character would be inserted
-    after the 255th character.  This could corrupt the line if the space
-    was inserted within a column name or keyword name token.
-
-Version 2.480beta  (used in the FTOOLS 5.3 release, 1 Nov 2003)
-
-  New Routines:
-
-  - fits_get_eqcoltype - just like fits_get_coltype, except in the
-    case of scaled integer columns, it returns the 'equivalent' 
-    data type that is necessary to store the scaled data values.  
-
-  - fits_split_names - splits an input string containing a comma or
-    space delimited list of names (typically file names or column
-    names) into individual name tokens.
-
-  Enhancements:
-
-  - changed fhist in histo.c so that it can make histograms of ASCII
-    table columns as well as binary table columns (as long as they
-    contain numeric data).
-
-  Bug fixes:
-
-  - removed an erroneous reference to listhead.c in makefile.vcc, that is
-    used to build the cfitsio dll under Windows.  This caused a 'main'
-    routine to be added to the library, which causes problems when linking
-    fortran programs to cfitsio under windows.
-
-  - if an error occurs when opening for a 2nd time (with ffopen) a file that
-    is already open (e.g., the specified extension doesn't exist), and
-    if the file had been modified before attempting to reopen it, then
-    the modified buffers may not get written to disk and the internal
-    state of the file may become corrupted.  ffclos was modified to
-    always set status=0 before calling ffflsh if the file has been 
-    concurrently opened more than once.
-
-Version 2.470 - 18 August 2003
-
-  Enhancements:
-
-  - defined 'TSBYTE' to represent the 'signed char' datatype (similar to
-    'TBYTE' that represents the 'unsigned char' datatype) and added
-    support for this datatype to all the routines that read or write
-    data to a FITS image or table.   This was implemented by adding 2
-    new C source code files to the package: getcolsb.c and putcolsb.c.
-
-  - Defined a new '1S' shorthand data code for a signed byte column in
-    a binary table.  CFITSIO will write TFORMn = '1B' and
-    TZEROn = -128 in this case, which is the convention used to
-    store signed byte values in a 'B' type column.
-
-  - in fitsio2.h, added test of whether  `__x86_64__` is defined, to 
-    support the new AMD Opteron 64-bit processor
-
-  - modified configure to not use the -fast compiler flag on Solaris
-    platforms when using the proprietary Solaris cc compiler.  This
-    flag causes compilation problems in eval_y.c (compiler just
-    hangs forever).
-
-  Bug fixes:
-
-  - In the special case of writing 0 elements to a vector table column
-    that contains 0 rows, ffgcpr no longer adds a blank row to the table.
-    
-  - added error checking code for cases where a ASCII string column
-    in a binary table is greater than 28800 characters wide, to avoid
-    going into an infinite loop.
-
-  - the fits_get_col_display_width routine was incorrectly returning
-    width = 0 for a 'A' binary table column that did not have an 
-    explicit vector length character.
-
-Version 2.460 - 20 May 2003
-
-  Enhancements:
-
-  - modified the HTTP driver in drvrnet.c so that CFITSIO can read
-    FITS files via a proxy HTTP server.  (This code was contributed by
-    Philippe Prugniel, Obs. de Lyon).  To use this feature, the 
-    'http_proxy' environment variable must be defined with the
-    address (URL) and port number of the proxy server, i.e.,
-      > setenv http_proxy http://heasarc.gsfc.nasa.gov:3128
-    will use port 3128 on heasarc.gsfc.nasa.gov
-
-  - suppressed some compiler warnings by casting a variable of 
-    type 'size_t' to type 'int' in fftkey (in fitscore.c) and
-    iraftofits and irafrdimge (in iraffits.c).
-
-Version 2.450 - 30 April 2003
-
-  Enhancements:
-
-  - modified the WCS keyword reading routine (ffgics) to support cases
-    where some of the CDi_j keywords are omitted (with an assumed 
-    value = 0).
-
-  - Made a change to http_open_network in drvrnet.c to add a 'Host: '
-    string to the open request.  This is required by newer HTTP 1.1
-    servers (so-called virtual servers).
-
-  - modified ffgcll (read logical table column) to return the illegal
-    character value itself if the FITS file contains a logical value that is
-    not equal to T, F or zero.  Previously it treated this case the
-    same as if the FITS file value was = 0.
-
-  - modified fits_movnam_hdu (ffmnhd) so that it will move to a tile-
-    compressed image (that is stored in a binary table) if the input
-    desired HDU type is BINARY_TBL as well as if the HDU type = IMAGE_HDU.
-
-  Bug fixes:
-
-  - in the routine that checks the data fill bytes (ffcdfl), the call
-    to ffmbyt should not ignore an EOF error when trying to read the bytes.
-    This is a little-used routine that is not called by any other CFITSIO
-    routine.
-
-  - fits_copy_file was not reporting an error if it hit the End Of File
-    while copying the last extension in the input file to the output file.
-
-  - fixed inconsistencies in the virtual file column filter parser
-    (ffedit_columns) to properly support expressions which create or
-    modify a keyword, instead of a column.  Previously it was only possible
-    to modify keywords in a table extension (not an image), and the 
-    keyword filtering could cause some of the table columns to not
-    get propagated into the virtual file.  Also, spaces are now
-    allowed within the specified keyword comment field.
-
-  - ffdtyp was incorrectly returning the data type of FITS keyword
-    values of the form '1E-09' (i.e., an exponential value without
-    a decimal point) as integer rather than floating point.
-
-  - The enhancement in the previous 2.440 release to allow more files to be
-    opened at one time introduced a bug: if ffclos is called with
-    a non-zero status value, then any subsequent call to ffopen will likely
-    cause a segmentation fault.  The fits_clear_Fptr routine was modified
-    to fix this.
-
-  - rearranged the order of some computations in fits_resize_img so as
-    to not exceed the range of a 32-bit integer when dealing with 
-    large images.
-
-  - the template parser routine, ngp_read_xtension, was testing for
-    "ASCIITABLE" instead of "TABLE" as the XTENSION value of an ASCII
-    table, and it did not allow for optional trailing spaces in the IMAGE"
-    or "TABLE" string value.
-
-Version 2.440 - 8 January 2003
-
-  Enhancements:
-
-  - modified the iterator function, ffiter, to operate on random
-    groups files.
-
-  - decoupled the NIOBUF (= 40) parameter from the limit on the number
-    FITS files that can be opened, so that more files may be opened
-    without the overhead of having to increase the number of NIOBUF
-    buffers.  A new NMAXFILES parameter is defined in fitsio2.h which sets
-    the maximum number of opened FITS files.  It is set = 300 by default.
-    Note however, that the underlying compiler or operating system may
-    not allow this many files to be opened at one time.
-
-  - updated the version of cfortran.h that is distributed with CFITSIO from 
-    version 3.9 to version 4.4.  This required changes to f77_wrap.h
-    and f77_wrap3.c.  The original cfortran.h v4.4 file was modified
-    slightly to support CFITSIO and ftools (see comments in the header
-    of cfortran.h).
-
-  - modified ffhist so that it copies all the non-structural keywords from
-    the original binary table header to the binned image header.
-
-  - modified fits_get_keyclass so that it recognizes EXTNAME =
-    COMPRESSED_IMAGE as a special tile compression keyword.
-
-  - modified Makefile.in to support the standard --prefix convention
-    for specifying the install target directory.
-
-  Bug fixes:
-
-  - in fits_decompress_img, needed to add a call to ffpscl to turn
-    off the BZERO and BSCALE scaling when reading the compressed image.
-
-Version 2.430 - 4 November 2002
-
-  Enhancements:
-
-  - modified fits_create_hdu/ffcrhd so that it returns without doing
-    anything and does not generate an error if the current HDU is 
-    already an empty HDU.  There is no need in this case to append
-    a new empty HDU to the file.
-
-  - new version of group.c (supplied by B. O'Neel at the ISDC) fixes 2
-    limitations:  1 - Groups now have 256 characters rather than 160
-    for the path lengths in the group tables. - ISDC SPR 1720.  2 -
-    Groups now can have backpointers longer than 68 chars using the long
-    string convention. - ISDC SPR 1738.
-
-  - small change to f77_wrap.h and f77_wrap3.c to support the fortran
-    wrappers on SUN solaris 64-bit sparc systems (see also change to v2.033)
-
-  - small change to find_column in  eval_f.c to support unsigned long
-    columns in binary tables (with TZEROn = 2147483648.0)
-
-  - small modification to cfortran.h to support Mac OS-X, (Darwin)
-
-  Bug fixes:
-
-  - When reading tile-compress images, the BSCALE and BZERO scaling
-    keywords were not being applied, if present.
-
-  - Previous changes to the error message stack code caused the
-    tile compressed image routines to not clean up spurious error
-    messages properly.
-
-  - fits_open_image was not skipping over null primary arrays.
-
-Version 2.420 - 19 July 2002
-
-  Enhancements:
-
-  - modified the virtual filename parser to support exponential notation
-    when specifying the min, max or binsize in a binning specifier, as in:
-    myfile.fits[binr X=1:10:1.0E-01, Y=1:10:1.0E-01]
-
-  - removed the limitation on the maximum number of HDUs in a FITS file 
-    (limit used to be 1000 HDUs per file).  Now any number of HDUs
-    can be written/read in a FITS file. (BUT files that have huge numbers
-    of HDUs can be difficult to manage and are not recommended);
-
-  - modified grparser.c to support HIERARCH keywords, based on 
-    code supplied by Richard Mathar (Max-Planck)
-
-  - moved the ffflsh (fits_flush_buffer) from the private to the
-    public interface, since this routine may be useful for some  
-    applications.  It is much faster than ffflus.
-
-  - small change to the definition of OFF_T in fitsio.h to support
-    large files on IBM AIX operating systems.
-
-  Bug fixes:
-
-  - fixed potential problem reading beyond array bounds in ffpkls.  This
-    would not have affected the content of any previously generated FITS
-    files.
-
-  - in the net driver code in drvrnet.c, the requested protocol string
-    was changed from "http/1.0" to "HTTP/1.0" to support apache 1.3.26.
-
-  - When using the virtual file syntax to open a vector cell in a binary
-    table as if it were a primary array image, there was a bug
-    in fits_copy_image_cell which garbled the data if the vector
-    was more than 30000 bytes long.
-
-  - fixed problem that caused fits_report_error to crash under Visual
-    C++ on Windows systems.  The fix is to use the '/MD' switch
-    on the cl command line, or, in Visual Studio, under project
-    settings / C++ select use runtime library multithreaded DLL
-
-  - modified ffpscl so it does not attempt to reset the scaling values
-    in the internal structure if the image is tile-compressed.
-
-  - fixed multiple bugs in mem_rawfile_open which affected the case
-    where a raw binary file is read and converted on the fly into
-    a FITS file.
-
-  - several small changes to group.c to suppress compiler warnings.
-
-Version 2.410 - 22 April 2002 (used in the FTOOLS 5.2 release)
-
-  New Routines:
-
-  - fits_open_data behaves similarly to fits_open_file except that it
-    also will move to the first HDU containing significant data if
-    and an explicit HDU name or number to open was not specified.
-    This is useful for automatically skipping over a null primary
-    array when opening the file.
-
-  - fits_open_table and fits_open_image behaves similarly to 
-    fits_open_data, except they move to the first table or image
-    HDU in the file, respectively.
-
-  - fits_write_errmark and fits_clear_errmark routines can be use
-    to write an invisible marker to the CFITSIO error stack, and
-    then clear any more recent messages on the stack, back to 
-    that mark.  This preserves any older messages on the stack.
-
-  - fits_parse_range utility routine parses a row list string
-    and returns integer arrays giving the min and max row in each
-    range.
-
-  - fits_delete_rowrange deletes a specified list of rows or row
-    ranges.
-
-  - fits_copy_file copies all or part of the HDUs in the input file
-    to the output file.
-
-  - added fits_insert_card/ffikey to the publicly defined set
-    of routines (previously, it was a private routine).
-
-  Enhancements:
-
-  - changed the default numeric display format in ffgkys from 'E' format
-    to 'G' format, and changed the format for 'X' columns to a 
-    string of 8 1s or 0s representing each bit value.
-
-  - modified ffflsh so the system 'fflush' call is not made in cases
-    where the file was opened with 'READONLY' access.
-
-  - modified the output filename parser so the "-.gz", and "stdout.gz"
-    now cause the output file to be initially created in memory,
-    and then compressed and written out to the stdout stream when
-    the file is closed.
-
-  - modified the routines that delete rows from a table to also 
-    update the variable length array heap, to remove any orphaned
-    data from the heap.
-
-  - modified ffedit_columns so that wild card characters may be
-    used when specifying column names in the 'col' file filter
-    specifier (e.g.,  file.fits[col TIME; *RAW] will create a
-    virtual table contain only the TIME column and any other columns
-    whose name ends with 'RAW').
-
-  - modified the keyword classifier utility, fits_get_keyclass, to
-    support cases where the input string is just the keyword name,
-    not the entire 80-character card.
-
-  - modified configure.in and configure to see if a proprietary
-    C compiler is available (e.g. 'cc'), and only use 'gcc' if not.
-
-  - modified ffcpcl (copy columns from one table to another) so that
-    it also copies any WCS keywords related to that column.
-
-  - included an alternate source file that can be used to replace
-    compress.c, which is distributed under the GNU General Public
-    License.  The alternate file contains non-functional stubs for
-    the compression routines, which can be used to make a version of
-    CFITSIO that does not have the GPL restrictions (and is also less
-    functional since it cannot read or write compressed FITS files).
-
-  - modifications to the iterator routine (ffiter) to support writing
-    tile compressed output images.
-
-  - modified ffourl to support the [compress] qualifier when specifying
-    the optional output file name. E.g., file.fit(out.file[compress])[3]
-
-  - modified imcomp_compress_tile to fully support implicit data type
-    conversion when writing to tile-compressed images.  Previously,
-    one could not write a floating point array to an integer compressed
-    image.
-
-  - increased the number of internal 2880-byte I/O buffers allocated
-    by CFITSIO from 25 to 40, in recognition of the larger amount
-    of memory available on typical machines today compared with
-    a few years ago.  The number of buffers can be set by the user
-    with the NIOBUF parameter in fitsio2.h.  (Setting this too large
-    can actually hurt performance).
-
-  - modified the #if statements in fitsio2.h, f77_wrap.h and f77_wrap1.c
-    to support the new Itanium 64-bit Intel PC.
-
-  - a couple minor modifications to fitsio.h needed to support the off_t
-    datatype on debian linux systems.
-
-  - increased internal buffer sizes in ffshft and ffsrow to improve
-    the I/O performance.
-
-  Bug fixes:
-
-  - fits_get_keyclass could sometimes try to append to an unterminated 
-    string, causing an overflow of a string array.   
-
-  - fits_create_template no longer worked because of improvements made
-    to other routines.  Had to modify ffghdt to not try to rescan
-    the header keywords if the file is still empty and contains no
-    keywords yet.
-
-  - ffrtnm, which returns the root filename, sometimes did not work 
-    properly when testing if the 'filename+n' convention was used for
-    specifying an extension number.
-
-  - fixed minor problem in the keyword template parsing routine, ffgthd
-    which in rare cases could cause an improperly terminated string to
-    be returned.
-
-  - the routine to compare 2 strings, ffcmps, failed to find a match 
-    in comparing strings like "*R" and "ERROR" where the match occurs
-    on the last character, but where the same matching character occurs
-    previously in the 2nd string.
-
-  - the region file reading routine (ffrrgn) did not work correctly if
-    the region file (created by POW and perhaps other programs) had an
-    'exclude' region (beginning with a '-' sign) as the first region 
-    in the file.  In this case all points outside the excluded region
-    should be accepted, but in fact no points were being accepted
-    in this case.
-
-Version 2.401 - 28 Jan 2002
-
-  - added the imcopy example program to the release (and Makefile)
-
-  Bug fixes:
-
-  - fixed typo in the imcompress code which affected compression
-    of 3D datacubes.
-
-  - made small change to fficls (insert column) to allow colums with
-    TFORMn = '1PU' and '1PV' to be inserted in a binary table.  The
-    'U' and 'V' are codes only used within CFITSIO to represent unsigned
-    16-bit and 32-bit integers; They get replaced by '1PI' and '1PJ'
-    respectively in the FITS table header, along with the appropriate
-    TZEROn keyword.
-
-Version 2.400 - 18 Jan 2002
-
-  (N.B.: Application programs must be recompiled, not just relinked 
-     with the new CFITSIO library because of changes made to fitsio.h)
-
-  New Routines:
-
-  - fits_write_subset/ffpss writes a rectangular subset (or the whole
-    image) to a FITS image.
-
-  - added a whole new family of routines to read and write arrays of 
-    'long long' integers (64-bit) to FITS images or table columns.  The
-    new routine names all end in 'jj':  ffpprjj, ffppnjj, ffp2djj,
-    ffp3djj, ffppssjj, ffpgpjj, ffpcljj, ffpcnjj. ffgpvjj, ffgpfjj,
-    ffg2djj, ffg3djj, ffgsvjj, ffgsfjj, ffggpjj, ffgcvjj, and ffgcfjj.
-
-  - added a set of helper routines that are used in conjunction with
-    the new support for tiled image compression.  3 routines set the
-    parameters that should be used when CFITSIO compresses an image:
-        fits_set_compression_type
-        fits_set_tile_dim
-        fits_set_noise_bits
-
-      3 corresponding routines report back the current settings:
-        fits_get_compression_type
-        fits_get_tile_dim
-        fits_get_noise_bits
-
-  Enhancements:
-
-  - major enhancement was made to support writing to tile-compressed
-    images.  In this format, the image is divided up into a rectangular
-    grid of tiles, and each tile of pixels is compressed individually
-    and stored in a row of a variable-length array column in a binary
-    table.  CFITSIO has been able to transparently read this compressed
-    image format ever since version 2.1.  Now all the CFITSIO image
-    writing routines also transparently support this format.  There are
-    2 ways to force CFITSIO to write compressed images: 1) call the
-    fits_set_compression_type routine before writing the image header
-    keywords, or 2), specify that the image should be compressed when
-    entering the name of the output FITS file, using a new extended
-    filename syntax.  (examples: "myfile.fits[compress]" will use the
-    default compression parameters, and "myfile.fits[compress GZIP
-    100,100] will use the GZIP compression algorithm with 100 x 100
-    pixel tiles.
-
-  - added new driver to support creating output .gz compressed fits
-    files.  If the name of the output FITS file to be created ends with
-    '.gz' then CFITSIO will initially write the FITS file in memory and
-    then, when the FITS file is closed, CFITSIO will gzip the entire
-    file before writing it out to disk.
-
-  - when over-writing vectors in a variable length array in a binary
-    table, if the new vector to be written is less than or equal to
-    the length of the previously written vector, then CFITSIO will now
-    reuse the existing space in the heap, rather than always appending
-    the new array to the end of the heap.
-
-  - modified configure.in to support building cfitsio as a dynamic 
-    library on Mac OS X. Use 'make shared' like on other UNIX platforms,
-    but a .dylib file will be created instead of .so.  If installed in a 
-    nonstandard location, add its location to the DYLD_LIBRARY_PATH 
-    environment variable so that the library can be found at run time.
-
-  - made various modifications to better support the  8-byte long integer
-    datatype on more platforms.  The 'LONGLONG' datatype is typedef'ed
-    to equal 'long long' on most Unix platforms and MacOS, and equal
-    to '__int64' on Windows machines.
-
-  - modified configure.in and makefile.in to better support cases 
-    where the system has no Fortran compiler and thus the f77 wrapper
-    routines should not be compiled.
-
-  - made small modification to eval.y and eval_y.f to get rid of warning
-    on some platforms about redefinition of the 'alloca'.
-
-  Bug fixes:
-
-  - other recent bug fixes in ffdblk (delete blocks) caused ffdhdu (delete
-    HDU) to fail when trying to replace the primary array with a null
-    primary array.
-
-  - fixed bug that prevented inserting a new variable length column
-    into a table that already contained variable length data.
-
-  - modified fits_delete_file so that it will delete the file even if
-    the input status value is not equal to zero.
-
-  - in fits_resize_image, it was sometimes necessary to call ffrdef to
-    force the image structure to be defined.
-
-  - modified the filename parser to support input files with names like:
-    "myfile.fits.gz(mem://tmp)" in which the url type is specified for
-    the output file but not for the input file itself.  This required
-    modifications to ffiurl and ffrtnm.

-Version 2.301 -   7 Dec 2001
-
-  Enhancements:
-
-   - modified the http file driver so that if the filename to be opened
-     contains a '?' character (most likely a cgi related string) then it
-     will not attempt to append a .gz or .Z as it would normally do.
-
-   - added support for the '!' clobber character when specifying
-     the output disk file name in CFITSIO's extended filename syntax, e.g.,
-     'http://a.b.c.d/myfile.fits.gz(!outfile.fits)'
-
-   - added new device driver which is used when opening a compressed FITS
-     file on disk by uncompressing it into memory with READWRITE
-     access.  This happens when specifying an output filename
-     'mem://'.
-
-   - added 2 other device drivers to open http and ftp files in memory
-     with write access.
-
-   - improved the error trapping and reporting in cases where program
-     attempts to write to a READONLY file (especially in cases where the
-    'file' resides in memory, as is the case when opening an ftp or http
-     file.
-
-   - modified the extended filename parser so that it is does not confuse
-     the bracket character '[' which is sometimes used in the root name
-     of files of type 'http://', as the start of an extname or row filter
-     expression.  If the file is of type 'http://', the parser now
-     checks to see if the last character in the extended file name is
-     a ')' or ']'.  If not, it does not try to parse the file name
-     any further.
-
-   - improved the efficiency when writing FITS files in memory, by
-     initially allocating enough memory for the entire HDU when it is
-     created, rather than incrementally reallocing memory 2880 bytes
-     at a time (modified ffrhdu and mem_truncate).  This change also
-     means that the program will fail much sooner if it cannot allocate
-     enough memory to hold the entire FITS HDU.
-
-  Bug fixes:
-
-   - There was an error in the definition of the Fortran ftphtb wrapper
-     routine (writes required ASCII table header keywords) that caused
-     it to fail on DEC OSF and other platforms where sizeof(long) = 8.
-
-Version 2.300 - 23 Oct 2001
-
-  New Routines:
-
-   - fits_comp_img and fits_decomp_img are now fully supported and
-     documented.  These routine compress and decompress, respective,
-     a FITS image using a new algorithm in which the image is first
-     divided into a grid of rectangular tiles, then the compressed byte
-     stream from each tile is stored in a row of a binary table.
-     CFITSIO can transparently read FITS images stored in this
-     compressed format.  Compression ratios of 3 - 6 are typically
-     achieved.  Large compression ratios are achieved for floating
-     point images by throwing away non-significant noise bits in the
-     pixel values.
-
-   - fits_test_heap tests the integrity of the binary table heap and
-     returns statistics on the amount of unused space in the heap and
-     the amount of space that is pointed to by more than 1 descriptor.
-
-   - fits_compress_heap which will reorder the arrays in the binary
-     table heap, recovering any unused space.
-
-  Enhancements:
-
-   - made substantial internal changes to the code to support FITS
-     files containing 64-bit integer data values.  These files have
-     BITPIX = 64 or TFORMn = 'K'.  This new feature in CFITSIO is
-     currently only enabled if SUPPORT_64BIT_INTEGERS is defined = 1 in
-     the beginning of the fitsio2.h file.  By default support for
-     64-bit integers is not enabled.
-
-   - improved the ability to read and return a table column value as a
-     formatted string by supporting quasi-legal TDISPn values which
-     have a lowercase format code letter, and by completely ignoring
-     other unrecognizable TDISPn values.  Previously, unrecognized
-     TDISPn values could cause zero length strings to be returned.
-
-   - made fits_write_key_longstr more efficient when writing keywords
-     using the long string CONTINUE convention.  It previously did not
-     use all the available space on each card when the string to be
-     written contained many single quote characters.
-
-   - added a new "CFITSIO Quick Start Guide" which provides all the
-     basic information needed to write C programs using CFITSIO.
-
-   - updated the standard COMMENT keywords that are written at the 
-     beginning of every primary array to refer to the newly published
-     FITS Standard document in Astronomy and Astrophysics.
-     Note: because of this change, any FITS file created with this
-     version of CFITSIO will not be identical to the same file written
-     with a previous version of CFITSIO.
-
-   - replaced the 2 routines in pliocomp.c with new versions provided by
-     D Tody and N Zarate.  These routines compress/uncompress image pixels
-     using the IRAF pixel list compression algorithm.
-
-   - modified fits_copy_hdu so that when copying a Primary Array
-     to an Image extension, the COMMENT cards which give the reference
-     to the A&A journal article about FITS are not copied.  In the
-     inverse case the COMMENT keywords are inserted in the header.
-     
-   - modified configure and Makefile.in to add capability to build a
-     shared version of the CFITSIO library.  Type 'make shared' or 
-     'make libcfitsio.so' to invoke this option.
-
-   - disabled some uninformative error messages on the error stack:
-       1) when calling ffclos (and then ffchdu) with input status > 0
-       2) when ffmahd tries to move beyond the end of file.
-     The returned status value remains the same as before, but the
-     annoying error messages no longer get written to the error stack.
-
-   - The syntax for column filtering has been modified so that
-     if one only specifies a list of column names, then only those
-     columns will be copied into the output file.  This provides a simple
-     way to make a copy of a table containing only a specified list of
-     columns.  If the column specifier explicitly deletes a column, however,
-     than all the other columns will be copied to the filtered input
-     file, regardless of whether the columns were listed or not.
-     Similarly, if the expression specifies only a column to be modified
-     or created, then all the other columns in the table will be
-     copied.
-
-      mytable.fit[1][col Time;Rate]  - only the Time and Rate
-        columns will be copied to the filtered input file.
-
-      mytable.fit[1][col -Time ] - all but the Time column are copied
-        to the filtered input file.
-
-      mytable.fit[1][col Rate;-Time] - same as above.
-
-   - changed a '#if defined' statement in f77_wrap.h and f77_wrap1.c 
-     to support the fortran wrappers on 64-bit IBM/RS6000 systems
-
-   - modified group.c so that when attaching one group (the child) to 
-     another (the parent), check in each file for the existence of a 
-     pointer to the other before adding the link. This is to prevent
-     multiple links from forming under all circumstances.
-
-   - modified the filename parser to accept 'STDIN', 'stdin', 
-     'STDOUT' and 'stdout' in addition to '-' to mean read the
-     file from standard input or write to standard output.
-
-   - Added support for reversing an axis when reading a subsection
-     of a compressed image using the extended filename syntax, as in
-     myfile.fits+1[-*, *] or myfile.fits+1[600:501,501:600]
-
-   - When copying a compressed image to a uncompressed image, the
-     EXTNAME keyword is no longer copied if the value is equal to
-     'COMPRESSED_IMAGE'.
-
-   - slight change to the comment field of the DATE keyword to reflect
-     the fact that the Unix system date and time is not true UTC time.
-
-  Bug fixes:
-
-   - fits_write_key_longstr was not writing the keyword if a null
-     input string value was given.
-
-   - writing data to a variable length column, if that binary table is not
-     the last HDU in the FITS file, might overwrite the following HDU.
-     Fixed this by changing the order of a couple operations in ffgcpr.
-
-   - deleting a column from a table containing variable length columns
-     could cause the last few FITS blocks of the file to be reset = 0.
-     This bug occurred as a result of modifications to ffdblk in v2.202.
-     This mainly affects users of the 'compress_fits' utility
-     program.
-
-   - fixed obscure problem when writing bits to a variable length 'B' 
-     column.
-
-   - when reading a subsection of an image, the BSCALE and BZERO pixel
-     scaling may not have been applied when reading image pixel values
-     (even though the scaling keywords were properly written in the
-     header).
-
-   - fits_get_keyclass was not returning 'TYP_STRUCT_KEY' for the
-     END keyword.
-
-Version 2.204 - 26 July 2001 
-
-  Bug fixes:
-
-   - Re-write of fits_clean_url in group.c to solve various problems
-     with invalid bounds checking.
-
-Version 2.203 -  19 July 2001 (version in FTOOLS v5.1)
-
-  Enhancements:
-
-   - When a row selection or calculator expression is written in
-     an external file (and read by CFITSIO with the '@filename' syntax)
-     the file can now contain comment lines.  The comment line must
-     begin with 2 slash characters as the first 2 characters on the
-     line.  CFITSIO will ignore the entire line when reading the
-     expression.
-
-  Bug fixes:
-
-   - With previous versions of CFITSIO, the pixel values in a FITS
-     image could be read incorrectly in the following case: when
-     opening a subset of a FITS image (using the
-     'filename.fits[Xmin:Xmax,Ymin:Ymax]' notation) on a PC linux, PC
-     Windows, or DEC OSF machine (but not on a SUN or Mac).  This
-     problem only occurs when reading more than 8640 bytes of data
-     (2160 4-byte integers) at a time, and usually only occurs if the
-     reading program reads the pixel data immediately after opening the
-     file, without first reading any header keywords.  This error would
-     cause strips of zero valued pixels to appear at semi-random
-     positions in the image, where each strip usually would be 2880
-     bytes long.  This problem does not affect cases where the input
-     subsetted image is simply copied to a new output FITS file.
-
-
-Version 2.202 -  22 May 2001
-
-  Enhancements:
-
-   - revised the logic in the routine that tests if a point is
-     within a region:  if the first region is an excluded region,
-     then it implicitly assumes a prior include region covering
-     the entire detector.  It also now supports cases where a 
-     smaller include region is within a prior exclude region.
-
-   - made enhancement to ffgclb (read bytes) so that it can
-     also read values from a logical column, returning an array
-     of 1s and 0s.  
-
-   - defined 2 new grouping error status values (349, 350) in 
-     cfitsio.h and made minor changes to group.c to use these new
-     status values.
-
-   - modified fits_open_file so that if it encounters an error while
-     trying to move to a user-specified extension (or select a subset
-     of the rows in an input table, or make a histogram of the
-     column values) it will close the input file instead of leaving
-     it open.
-
-   - when using the extended filename syntax to filter the rows in
-     an input table, or create a histogram image from the values in
-     a table column, CFITSIO now writes HISTORY keywords in the 
-     output file to document the filtering expression that was used.
-
-  Bug fixes:
-
-   - ffdblk (called by ffdrow) could overwrite the last FITS block(s) in 
-     the file in some cases where one writes data to a variable length
-     column and then calls ffdrow to delete rows in the table.  This
-     bug was similar to the ffiblk bug that was fixed in v2.033.
-
-   - modified fits_write_col_null to fix a problem which under unusual
-     circumstances would cause a End-of-File error when trying to
-     read back the value in an ASCII string column, after initializing
-     if by writing a null value to it. 
-
-   - fixed obscure bug in the calculator function that caused an
-     error when trying to modify the value of a keyword in a HDU
-     that does not have a NAXIS2 keyword (e.g., a null primary array).
-
-   - the iterator function (in putcol.c) had a bug when calculating
-     the optimum number rows to process in the case where the table
-     has very wide rows (>33120 bytes) and the calculator expression
-     involves columns from more than one FITS table.  This could
-     cause an infinite loop in calls to the ffcalc calculator function.
-
-   - fixed bug in ffmvec, which modifies the length of an 
-     existing vector column in a binary table.  If the vector
-     was reduced in length, the FITS file could sometimes be left
-     in a corrupted state, and in all cases the values in the remaining
-     vector elements of that column would be altered.
-
-   - in drvrfile.c, replaced calls to fsetpos and fgetpos with
-     fseek and ftell (or fseeko and ftello) because the fpos_t
-     filetype used in fsetpos is incompatible with the off_t
-     filetype used in fseek, at least on some platforms (Linux 7.0).
-     (This fix was inserted into the V2.201 release on April 4).
-
-   - added "#define fits_write_pixnull ffppxn" to longnam.h
-
-Version 2.201 - 15 March 2001
-
-  Enhancements
-
-   - enhanced the keyword reading routines so that they will do
-     implicit datatype conversion from a string keyword value
-     to a numeric keyword value, if the string consist of a
-     valid number enclosed in quotes.  For example, the keyword
-     mykey = '37.5' can be read by ffgkye.
-
-   - modified ffiimg so that it is possible to insert a new
-     primary array at the beginning of the file.  The original
-     primary array is then converted into an IMAGE extension.
-
-   - modified ffcpdt (copy data unit) to support the case where 
-     the data unit is being copied between 2 HDUs in the same file.
-
-   - enhanced the fits_read_pix and fits_read_pixnull routines so
-     that they support the tiled image compression format that the
-     other image reading routines also support.
-
-   - modified the Extended File Name syntax to also accept a 
-     minus sign (-) as well as an exclamation point (!) as
-     the leading character when specifying a column or or keyword
-     to be deleted, as in [col -time] will delete the TIME column.
-
-   - now completely support reading subimages, including pixel
-     increments in each dimension, for tile-compressed images
-     (where the compressed image tiles are stored in a binary
-      table).
-
-  Bug fixes:
-
-   - fixed confusion in the use of the fpos_t and off_t datatypes
-     in the fgetpos and fsetpos routines in drvrfile.c which caused
-     problems with the Windows VC++ compiler.  (fpos_t is not 
-     necessarily identical to off_t)
-
-   - fixed a typo in the fits_get_url function in group.c which 
-     caused problems when determining the relative URL to a compressed
-     FITS file.
-
-   - included fitsio.h in the shared memory utility program,
-     smem.c, in order to define OFF_T. 
-
-   - fixed typo in the datatype of 'nullvalue' in ffgsvi, which caused
-     attempts to read subsections of a short integer tiled compressed
-     image to fail with a bus error.    
-
-   - fixed bug in ffdkey which sometimes worked incorrectly if one 
-     tried to delete a nonexistent keyword beyond the end of the header.
-
-   - fixed problem in fits_select_image_section when it writes a dummy
-     value to the last pixel of the section.  If the image contains
-     scaled integer pixels, then in some cases the pixel value could end
-     up out of range.
-
-   - fixed obscure bug in the ffpcn_ family of routines which gave
-     a floating exception when trying to write zero number of pixels to
-     a zero length array  (why would anyone do this?)
-
-Version 2.200 - 26 Jan 2001
-
-  Enhancements
-
-   - updated the region filtering code to support the latest region
-     file formats that are generated by the POW, SAOtng and ds9
-     programs.  Region positions may now be given in HH:MM:SS.s,
-     DD:MM:SS.s format, and region sizes may be given arcsec or arcmin
-     instead of only in pixel units.  Also changed the logic so that if
-     multiple 'include' regions are specified in the region file, they
-     are ORed together, instead of ANDed, so that the filtering keeps
-     points that are located within any of the 'include' regions, not
-     just the intersection of the regions.
-
-   - added support for reading raw binary data arrays by converting
-     them on the fly into virtual FITS files.
-
-   - modified ffpmsg, which writes error messages to CFITSIO's internal
-     error stack, so that messages > 80 characters long will be wrapped
-     around into multiple 80 character messages, instead of just
-     being truncated at 80 characters.
-
-   - modified the CFITSIO parser so that expression which involve
-     scaled integer columns get cast to double rather than int.
-
-   - Modified the keyword template parsing routine, ffgthd, to
-     support the HIERARCH keyword.
-
-   - modified ffainit and ffbinit so that they don't unnecessarily
-     allocate 0 bytes of memory if there are no columns (TFIELDS = 0)
-     in the table that is being opened.
-
-   - modified fitsio2.h to support NetBSD on Alpha OSF platforms
-     (NetBSD does not define the '__unix__' symbol).
-
-   - changed the way OFF_T is defined in fitsio.h for greater
-     portability.
-
-   - changed drvrsmem.c so it is compiled only when HAVE_SHMEM_SERVICES
-     is defined in order to removed the conditional logic from the Makefile
-
-   - reorganized the CFITSIO User's guide to make it
-     clearer and easier for new users to learn the basic routines.
-
-   - fixed ffhdef (which reserves space for more header keywords) so
-     that is also updates the start position of the next HDU.  This
-     affected the offset values returned by ffghof.
-
-Version 2.100 - 18 Oct 2000
-
-  Enhancements
-
-   - made substantial modification to the code to support Large files,
-     i.e., files larger than 2**31 bytes = 2.1GB.  FITS files up to
-     6 terabytes in size may now be read and written on platforms
-     that support Large files (currently only Solaris).
-
-   - modified ffpcom and ffphis, which write COMMENT and HISTORY 
-     keywords, respectively, so that they now use columns 9 - 80, 
-     instead of only columns 11 - 80.  Previously, these routines
-     avoided using columns 9 and 10, but this is was unnecessarily
-     restrictive.
-
-   - modified ffdhdu so that instead of refusing to delete the 
-     primary array, it will replace the current primary array 
-     with a null primary array containing the bare minimum of
-     required keywords and no data.
-
-  New Routines
-
-   - fits_read_pix, fits_read_pixnull, fits_read_subset, and fits_write_pix
-     routines were added to enable reading and writing of Large images,
-     with more than 2.1e9 pixels.  These new routines are now recommended
-     as the basic routines for reading and writing all images.
-
-   - fits_get_hduoff returns the byte offset in the file to
-     the start and end of the current HDU.  This routine replaces the
-     now obsolete fits_get_hduaddr routine;  it uses 'off_t' instead of
-     'long' as the datatype of the arguments and can support offsets
-     in files greater than 2.1GB in size.
-
-  Bug fixes:
-
-   - fixed bug in fits_select_image_section that caused an integer
-     overflow when reading very large image sections (bigger than
-     8192 x 8192 4-byte pixels).
-
-   - improved ffptbb, the low-level table writing routine, so that 
-     it will insert additional rows in the table if the table is
-     not already big enough.  Previously it would have just over-
-     written any HDUs following the table in the FITS file.
-
-   - fixed a bug in the  fits_write_col_bit/ffpclx routine which
-     could not write to a bit 'X' column if that was the first column
-     in the table to be written to.  This bug would not appear if
-     any other datatype column was written to first.
-
-   - non-sensible (but still formally legal) binary table TFORM values
-     such as '8A15', or '1A8' or 'A8' would confuse CFITSIO and cause it
-     to return a 308 error.  When parsing the TFORMn = 'rAw' value,
-     the ffbnfm routine has been modified to ignore the 'w' value in cases 
-     where w > r.
-
-   - fixed bug in the blsearch routine in iraffits.c which sometimes
-     caused an out-of-bounds string pointer to be returned when searching
-     for blank space in the header just before the 'END' keyword.
-
-   - fixed minor problem in ffgtcr in group.c, which sometimes failed
-     while trying to move to the end of file before appending a
-     grouping table.
-
-   - on Solaris, with Sun CC 5.0, one must check for '__unix' rather
-     than '__unix__' or 'unix' as it's symbol.  Needed to modify this
-     in drvrfile.c in 3 places.
-
-   - in ffextn, the FITS file would be left open if the named
-     extension doesn't exist, thus preventing the file from being
-     opened again later with write access.
-
-   - fixed bug in ffiimg that would cause attempts to insert a new
-     image extension following a table extension, and in front of any
-     other type of extension, to fail.
-
-Version 2.037 - 6 July 2000
-
-  Enhancements
-
-   - added support in the extended filename syntax for flipping
-     an image along any axis either by specifying a starting 
-     section pixel number greater than the ending pixel number,
-     or by using '-*' to flip the whole axis.  Examples:
-     "myfile.fits[1:100, 50:10]" or "myfile.fits[-*,*]".
-
-   - when reading a section of an image with the extended filename
-     syntax (e.g. image.fits[1:100:2, 1:100:2), any CDi_j WCS keywords
-     will be updated if necessary to transfer the world coordinate
-     system from the imput image to the output image section.
-
-   - on UNIX platforms, added support for filenames that begin
-     with "~/" or "~user/".  The "~" symbol will get expanded
-     into a string that gives the user's home directory.
-
-   - changed the filename parser to support disk file names that
-     begin with a minus sign.  Previously, the leading minus sign would
-     cause CFITSIO to try to read/write the file from/to stdin/stdout.
-
-   - modified the general fits_update_key routine, which writes
-     or updates a keyword value, to use the 'G' display format
-     instead of the 'E' format for floating point keyword values.
-     This will eliminate trailing zeros from appearing in the value.
-
-   - added support for the "-CAR" celestial coordinate projection
-     in the ffwldp and ffxypx routines.  The "-CAR" projection is
-     the default simplest possible linear projection.
-
-   - added new fits_create_memfile/ffimem routine to create a new
-     fits file at a designated memory location.
-
-   - ported f77_wrap.h and f77_wrap1.c so that the Fortran interface
-     wrappers work correctly on 64-bit SGI operating systems.  In this
-     environment, C 'long's  are 8-bytes long, but Fortran 'integers'
-     are still only 4-bytes long, so the words have to be converted
-     by the wrappers.
-
-   - minor modification to cfortran.h to automatically detect when it
-     is running on a linux platform, and then define f2cFortran in that
-     case.  This eliminates the need to define -Df2cFortran on the
-     command line.
-
-   - modified group.c to support multiple "/" characters in
-     the path name of the file to be opened/created.
-
-   - minor modifications to the parser (eval.y, eval_f.c, eval_y.c)
-     to a) add the unary '+' operator, and b) support copying the
-     TDIMn keyword from the input to the output image under certain
-     circumstances.
-
-   - modified the lexical parser in eval_l.y and eval_l.c to
-     support #NULL and #SNULL constants which act to set the
-     value to Null.  Support was also added for the C-conditional
-     expression: 'boolean ? trueVal : falseVal'.
-
-   - small modification to eval_f.c to write an error message to
-     the error stack if numerical overflow occurs when evaluating
-     an expression.
-
-   - configure and configure.in now support the egcs g77 compiler
-     on Linux platforms.
-
-  Bug fixes:
-
-   - fixed a significant bug when using the extended filename binning
-     syntax to generate a 2-dimensional image from a histogram of the
-     values in 2 table columns.  This bug would cause table events that
-     should have been located in the row just below the bottom row of
-     the image (and thus should have been excluded from the histogram)
-     to be instead added into the first row of the image.  Similarly,
-     the first plane of a 3-D or 4-D data cube would include the events
-     that should have been excluded as falling in the previous plane of
-     the cube.
-
-   - fixed minor bug when parsing an extended filename that contains
-     nested pairs of square brackets (e.g., '[col newcol=oldcol[9]]').
-
-   - fixed bug when reading unsigned integer values from a table or
-     image with fits_read_col_uint/ffgcvuk.  This bug only occurred on
-     systems like Digital Unix (now Tru64 Unix) in which 'long'
-     integers are 8 bytes long, and only when reading more than 7200
-     elements at a time.  This bug would generally cause the program to
-     crash with a segmentation fault.
-
-   - modified ffgcpr to update 'heapstart' as well as 'numrows' when
-     writing more rows beyond the end of the table.  heapstart
-     is needed to calculate if more space needs to be inserted in the
-     table when inserting columns into the table.
-
-   - modified fficls (insert column), ffmvec, ffdrow and ffdcol to 
-     not use the value of the NAXIS2 keyword as the number of rows
-     in the table, and instead use the value that is stored in
-     an internal structure, because the keyword value may not
-     be up to date.
-
-   - Fixed bug in the iterator function that affected the handling
-     of null values in string columns in ASCII and binary tables.
-
-   - Reading a subsample of pixels in very large images, (e.g., 
-     file = myfile.fits[1:10000:10,1:10000:10],  could cause a
-     long integer overflow (value > 2**31) in the computation of the
-     starting byte offset in the file, and cause a return error status
-     = 304 (negative byte address).  This was fixed by changing the
-     order of the arithmetic operations in calculating the value of
-     'readptr' in the ffgcli, ffgclj, ffgcle, ffgcld, etc. routines.
-
-   - In version 2.031, a fix to prevent compressed files from being
-     opened with write privilege was implemented incorrectly.  The fix
-     was intended to not allow a compressed FITS file to be opened
-     except when a local uncompressed copy of the file is being
-     produced (then the copy is opened with write access), but in fact
-     the opposite behavior occurred:  Compressed files could be opened
-     with write access, EXCEPT when a local copy is produced.   This
-     has been fixed in the mem_compress_open and file_compress_open
-     routines.
-
-   - in iraffits.c, a global variable called 'val' caused multiply
-     defined symbols warning when linking cfitsio and IRAF libraries.
-     This was fixed by making 'val' a local variable within the
-     routine.
-
-Version 2.036 - 1 Feb 2000
-
-   - added 2 new generic routines, ffgpf and ffgcf which are analogous
-     to ffgpv and ffgcv but return an array of null flag values instead
-     of setting null pixels to a reserved value.
-
-   - minor change to eval_y.c and eval.y to "define alloca malloc"
-     on all platforms, not just VMS.
-
-   - added support for the unsigned int datatype (TUINT) in the
-     generic ffuky routine and changed ffpky so that unsigned ints
-     are cast to double instead of long before being written to 
-     the header. 
-
-   - modified ffs2c so that if a null string is given as input then
-     a null FITS string (2 successive single quotes) will be returned.
-     Previously this routine would just return a string with a single
-     quote, which could cause an illegal keyword record to be written.
-
-   - The file flush operation on Windows platforms apparently
-     changes the internal file position pointer (!) in violation of the
-     C standard.  Put a patch into the file_flush routine to explicitly
-     seek back to the original file position.
-
-   - changed the name of imcomp_get_compressed_image_parms to
-     imcomp_get_compressed_image_par to not exceed the 31 character
-     limit on some compilers.
-
-   - modified the filename parser (which is used when moving to a
-     named HDU) to support EXTNAME values which contain embedded blanks.
-
-   - modified drvrnet.c to deal with ftp compressed files better so
-     that even fits files returned from cgi queries which have the wrong
-     mime types and/or wrong types of file names should still decompress.
-
-   - modified ffgics to reduce the tolerance for acceptable skewness
-     between the axes, and added a new warning return status = 
-     APPROX_WCS_KEY in cases where there is significant skewness
-     between the axes.
-
-   - fixed bug in ffgics that affected cases where the first coordinate
-     axis was DEC, not RA, and the image was a mirror image of the sky.
-
-   - fixed bug in ffhist when trying to read the default binning
-     factor keyword, TDBIN.
-
-   - modified ffhist so that is correctly computes the rotation angle
-     in a 2-D image if the first histogram column has a CROTA type
-     keyword but the 2nd column does not.
-
-   - modified ffcpcl so that it preserves the comment fields on the
-     TTYPE and TFORM keywords when the column is copied to a new file.
-
-   - make small change to configure.in to support FreeBSD Linux 
-     by setting CFLAGS = -Df2cFortran instead of -Dg77Fortran. Then
-     regenerated configure with autoconf 2.13 instead of 2.12.     
-
-Version 2.035 - 7 Dec 1999 (internal release only, FTOOLS 5.0.2)
-
-   - added new routine called fits_get_keyclass/ffgkcl that returns
-     the general class of the keyword, e.g., required structural 
-     keyword, WCS keyword, Comment keyword, etc.  15 classes of
-     keywords have been defined in fitsio.h
-
-   - added new routine called fits_get_img_parm/ffgipr that is similar
-     to ffgphd but it only return the bitpix, naxis, and naxisn values.
-
-   - added 3 new routines that support the long string keyword
-     convention: fits_insert_key_longstr, fits_modify_key_longstr
-     fits_update_key_longstr.
-
-   - modified ffgphd which reads image header keywords to support
-     the new experimental compressed image format.
-
-   - when opening a .Z compressed file, CFITSIO tries to allocate
-     memory equal to 3 times the file size, which may be excessive
-     in some cases.  This was changed so that if the allocation fails,
-     then CFITSIO will try again to allocate only enough memory
-     equal to 1 times the file size.  More memory will be allocated
-     later if this turns out to be too small.
-
-   - improved the error checking in the fits_insert_key routine
-     to check for illegal characters in the keyword.
-
-Version 2.034 - 23 Nov 1999
-
-   - enhanced support for the new 'CD' matrix world coordinate system
-     keywords in the ffigics routine.  This routine has been enhanced
-     to look for the new 'CD' keywords, if present, and convert them
-     back to the old CDELTn and CROTAn values, which are then returned.  
-     The routine will also swap the WCS parameters for the 2 axes if
-     the declination-like axis is the first WCS axis.
-
-   - modified ffphbn in putkey.c to support the 'U' and 'V" TFORM characters
-     (which represent unsigned short and unsigned int columns) in variable
-     length array columns.  (previously only supported these types in
-     fixed length columns).
-
-   - added checks when reading gzipped files to detect unexpected EOF.
-     Previously, the 'inflate_codes' routine would just sit in an infinite 
-     loop if the file ended unexpectedly.
-
-   - modified fits_verify_chksum/ffvcks so that checksum keywords with
-     a blank value string are treated as undefined, the same as
-     if the keyword did not exist at all.
-
-   - fixed ffghtb and ffghbn so that they return the extname value 
-     in cases where there are no columns in the table.
-
-   - fixed bug in the ffgtwcs routine (this is a little utility 
-     routine to aid in interfacing to Doug Mink's WCS routines);
-     it was not correctly padding the length of string-valued keywords
-     in the returned string.
-
-   - fixed bug in 'iraffits.c' that prevented Type-2 IRAF images from
-     being correctly byte-swapped on PCs and DEC-OSF machines.
-
-   - fixed tiny memory leak in irafncmp in iraffits.c.  Only relevant when
-     reading IRAF .imh files.
-
-   - fixed a bug (introduced in version 2.027) that caused the keyword
-     reading routines to sometimes not find a matching keyword if the
-     input name template used the '*' wildcard as the last character.
-     (e.g., if input name = 'COMMENT*' then it would not find the
-     'COMMENT' keywords.  (It would have found longer keywords like
-     'COMMENTX' correctly). The fix required a minor change to ffgcrd
-     in getkey.c
-
-   - modified the routine (ffswap8) that does byteswapping of
-     double precision numbers.  Some linux systems have reported floating
-     point exceptions because they were trying to interpret the bytes
-     as a double before the bytes had been swapped.
-
-   - fixed bug in the calculation of the position of the last byte
-     in the string of bits to be read in ffgcxuk and ffgcxui.  This
-     bug generally caused no harm, but could cause the routine to
-     exit with an invalid error message about trying to read
-     beyond the size of the field.
-
-   - If a unix machine did not have '__unix__', 'unix', or  '__unix'
-     C preprocessor symbols defined, then CFITSIO would correctly open
-     one FITS file, but would not correctly open subsequent files. Instead
-     it would think that the same file was being opened multiple times.
-     This problem has only been seen on an IBM/AIX machine. The fits_path2url
-     and fits_url2path routines in group.c were modified to fix the problem.
-
-   - fixed bug in group.c, which affected WINDOWS platforms only, that 
-     caused programs to go into infinite loop when trying to open
-     certain files.
-
-   - the ftrsim Fortran wrapper routine to ffrsim was not defined
-     correctly, which caused the naxis(2) value to be passed incorrectly
-     on Dec OSF machines, where sizeof(long) != sizeof(int).
-
-Version 2.033 - 17 Sept 1999
-
-   - New Feature: enhanced the row selection parser so that comparisons
-     between values in different rows of the table are allowed, and the
-     string comparisons with <, >, <=, and >= are supported.
-
-   - added new routine the returns the name of the keyword in the
-     input keyword record string.  The name is usually the first
-     8 characters of the record, except if the HIERARCH convention
-     is being used in which case the name may be up to 67 characters
-     long.
-
-   - added new routine called fits_null_check/ffnchk that checks to
-     see if the current header contains any null (ASCII 0) characters.
-     These characters are illegal in FITS headers, but they go undetected
-     by the other CFITSIO routines that read the header keywords.
-
-   - the group.c file has been replaced with a new version as supplied
-     by the ISDC.  The changes are mainly to support partial URLs and
-     absolute URLs more robustly.  Host dependent directory paths are
-     now converted to true URLs before being read from/written to
-     grouping tables.
-
-   - modified ffnmhd slightly so that it will move to the first extension
-     in which either the EXTNAME or the HDUNAME keyword is equal to the
-     user-specified name.  Previously, it only checked for HDUNAME if
-     the EXTNAME keyword did not exist.
-
-   - made small change to drvrnet.c so that it uncompress files 
-     which end in .Z and .gz just as for ftp files.
-
-   - rewrote ffcphd (copy header) to handle the case where the
-     input and output HDU are in the same physical FITS file.
-
-   - fixed bug in how long string keyword values (using the CONTINUE
-     convention) were read.  If the string keyword value ended in an
-     '&' character, then fits_read_key_longstr, fits_modify_key_str,
-     and fits_delete_key would interpret the following keyword as
-     a continuation, regardless of whether that keyword name was
-     'CONTINUE' as required by this convention.  There was also a bug
-     in that if the string keyword value was all blanks, then 
-     fits_modify_key_str could in certain unusual cases think
-     that the keyword ended in an '&' and go into an infinite loop.
-
-   - modified ffgpv so that it calls the higher level ffgpv_ routine
-     rather than directly calling the lower level ffgcl_ routine. This
-     change is needed to eventually support reading compressed images.
-
-   - added 3 new routines to get the image datatype, image dimensions,
-     and image axes length.  These support the case where the image is
-     compressed and stored in a binary table.
-
-   - fixed bug in ffiblk that could sometimes cause it to insert a
-     new block in a file somewhere in the middle of the data, instead
-     of at the end of the HDU.  This fortunately is a rare problem,
-     mainly only occurring in certain cases when  inserting rows in a binary 
-     table that contains variable length array data (i.e., has a heap).
-
-   - modified fits_write_tdim so that it double checks the TFORMn
-     value directly if the column repeat count stored in the internal
-     structure is not equal to the product of all the dimensions.
-
-   - fixed bug that prevented ffitab or ffibin from inserting a new
-     table after a null primary array (can't read NAXIS2 keyword).
-     Required a small change to ffrdef.
-
-   - modified testprog.c so that it will continue to run even if
-     it cannot open or process the template file testprog.tpt.
-
-   - modified the logic in lines 1182-1185 of grparser.c so that
-     it returns the correct status value in case of an error.
-
-   - added test in fitsio2.h to see if __sparcv9 is defined; this
-     identifies a machine running Solaris 7 in 64-bit mode where
-     long integers are 64 bits long.
-
-Version 2.032 - 25 May 1999
-
-   - the distribution .tar file was changed so that all the files
-     will be untarred into a  subdirectory by default instead of
-     into the current directory.
-
-   - modified ffclos so that it always frees the space allocated by
-     the fptr pointer, even when another fptr points to the same file.
-
-   - plugged a potential (but rare in practice) memory leak in ffpinit
-
-   - fixed bug in all the ffp3d_ and ffg3d_ routines in cases where
-     the data cube that has been allocated in memory has more planes
-     than the data cube in the FITS file.
-
-   - modified drvrsmem.c so that it allocates a small shared
-     memory segment only if CFITSIO tries to read or write a
-     FITS file in shared memory.  Previously it always allocated
-     the segment whether it was needed or not.  Also, this small
-     segment is removed if 0 shared memory segments remain in 
-     the system.
-
-   - put "static" in front of 7 DECLARE macros in compress.c
-     because these global variables were causing conflicts with other
-     applications programs that had variables with the same names.
-
-   - modified ffasfm to return datatype = TDOUBLE instead of TFLOAT
-     if the ASCII table column has TFORMn = 'Ew.d' with d > 6.
-
-   - modified the column reading routines to a) print out the offending
-     entry if an error occurs when trying to read a numeric ASCII table
-     column, and b) print out the column number that had the error
-     (the messages are written to CFITSIOs error stack)
-
-   - major updates to the Fortran FITSIO User's Guide to include many
-     new functions that have been added to CFITSIO in the past year.
-
-   - modified fitsio2.h so that the test for __D_FLOAT etc. is only
-     made on Alpha VMS machines, to avoid syntax errors on some other
-     platforms.
-
-   - modified ffgthd so that it recognizes a floating point value
-     that uses the 'd' or 'D' exponent character.
-
-   - removed the range check in fftm2s that returned an error if
-     'decimals' was less than zero.  A negative value is OK and is
-     used to return only the date and not the time in the string.
-
-Version 2.031 - 31 Mar 1999
-
-   - moved the code that updates the NAXIS2 and PCOUNT keywords from
-     ffchdu into the lower lever ffrdef routine.  This ensures that
-     other routines which call ffrdef will correctly update these 2
-     keywords if required.  Otherwise, for instance, calling 
-     fits_write_checksum before closing the HDU could cause the NAXIS2
-     keyword (number of rows in the table) to not be updated.
-
-   - fixed bug (introduced in version 2.030) when writing null values
-     to a primary array or image extension.  If trying to set more
-     than 1 pixel to null at a time, then typically only 1 null would
-     be written.  Also fixed related bug when writing null values to
-     rows in a table that are beyond the currently defined size of the
-     table (the size of the table was not being expanded properly).
-
-   - enhanced the extended filename parser to support '*' in image
-     section specifiers, to mean use the whole range of the axis.
-     myfile.fits[*,1:100] means use the whole range of the first
-     axis and pixels 1 to 100 in the second axis.  Also supports
-     an increment, as in myfile.fits[*:2, *:2] to use just the
-     odd numbered rows and columns.
-
-   - modified fitscore.c to set the initial max size of the header, when
-     first reading it, to the current size of the file, rather than to 
-     2 x 10**9 to avoid rare cases where CFITSIO ends up writing a huge 
-     file to disk.
-
-   - modified file_compress_open so that it will not allow a compressed
-     FITS file to be opened with write access.  Otherwise, a program
-     could write to the temporary copy of the uncompressed file, but
-     the modification would be lost when the program exits.
-
-Version 2.030 - 24 Feb 1999
-
-   - fixed bug in ffpclu when trying to write a null value to a row
-     beyond the current size of the table (wouldn't append new rows
-     like it should).
-
-   - major new feature:  enhanced the routines that read ASCII string
-     columns in tables so that they can read any table column, including
-     logical and numeric valued columns.  The column values are returned
-     as a formatted string.  The format is determined by the TDISPn
-     keyword if present, otherwise a default format based on the
-     datatype of the column is used.
-
-  -  new routine:  fits_get_col_display_width/ffgcdw returns the length
-     of the formatted strings that will be returned by the routines that
-     read table columns as strings. 
-
-   - major new feature:  added support for specifying an 'image section'
-     when opening an image:  e.g,  myfile.fits[1:512:2,2:512:2] to 
-     open a 256x256 pixel image consisting of the odd columns and the 
-     even numbered rows of the input image.
-
-   - added supporting project files and instructions for building 
-     CFITSIO under Windows NT with the Microsoft Visual C++ compiler.
-
-   - changed the variable 'template' to 'templt' in testprog.c since
-     it conflicted with a reserved word on some compilers.
-
-   - modified group.c to conditionally include sys/stat.h only on
-     unix platforms
-
-   - fixed bug in the ffiter iterator function that caused it to always
-     pass 'firstn' = 1 to the work function when reading from the
-     primary array or IMAGE extension. It worked correctly for tables.
-
-   - fixed bug in the template header keyword parser (ffgthd) in cases
-     where the input template line contains a logical valued keyword
-     (T or F) without any following comment string.  It was previously
-     interpreting this as a string-valued keyword.
-
-   - modified ffrhdu that reads and opens a new HDU, so that it
-     ignores any leading blank characters in the XTENSION name, e.g.,
-     XTENSION= '  BINTABLE' will not cause any errors, even though
-     this technically violates the FITS Standard.
-
-   - modified ffgtbp that reads the required table keywords to make
-     it more lenient and not exit with an error if the THEAP keyword
-     in binary tables cannot be read as an integer.  Now it will
-     simply ignore this keyword if it cannot be read.
-
-   - added test for 'WIN32' as well as '__WIN32__' in fitsio2.h,
-     eval.l and eval_l.c in a preprocessor statement.
-
-   - changed definition of strcasecmp and strncasecmp in fitsio2.h,
-     eval.l and eval_l.c to conform to the function prototypes under
-     the Alpha VMS v7.1 compiler.
-
-   - corrected the long function names in longnam.h for the new WCS 
-     utility functions in wcssubs.c
-
-Version 2.029 - 11 Feb 1999
-
-   - fixed bug in the way NANs and underflows were being detected on
-     VAX and Alpha VMS machines.
-
-   - enhanced the filename parser to distinguish between a VMS-style
-     directory name (e.g.  disk:[directory]myfile.fits) and a CFITSIO
-     filter specifier at the end of the name.
-
-   - modified ffgthd to support the HIERARCH convention for keyword
-     names that are longer than 8 characters or contain characters
-     that would be illegal in standard FITS keyword names.
-
-   - modified the include statements in grparser.c so that malloc.h 
-     and memory.h are only included on the few platforms that really
-     need them.
-
-   - modified the file_read routine in drvrfile.c to ignore the last
-     record in the FITS file it it only contains a single character that
-     is equal to 0, 10 or 32.  Text editors sometimes append a character
-     like this to the end of the file, so CFITSIO will ignore it and
-     treat it as if it had reached the end of file.
-
-   - minor modifications to fitsio.h to help support the ROOT environment.
-
-   - installed new version of group.c and group.h; the main change
-     is to support relative paths (e.g.  "../filename") in the URLs
-
-   - modified the histogramming routines so that it looks for the
-     default preferred column axes in a keyword of the form
-     CPREF = 'Xcol, Ycol'
-     instead of separate keywords of the form
-     CPREF1 = 'Xcol'
-     CPREF2 = 'Ycol'
-
-   - fixed bug so that if the binning spec is just a single integer,
-     as in  [bin 4] then this will be interpreted as meaning to make
-     a 2D histogram using the preferred or default axes, with the
-     integer taken as the binning factor in both axes.
-
-Version 2.028 - 27 Jan 1999
-
-   - if the TNULLn keyword value was outside the range of a 'I' or 'B'
-     column, an overflow would occur when setting the short or char 
-     to the TNULLn value, leading to incorrect values being flagged as
-     being undefined.  This has been fixed so that CFITSIO will ignore
-     TNULLn values that are beyond the range of the column data type.
-
-   - changed a few instances of the string {"\0"} to {'\0'} in the
-     file groups.c
-
-   - installed new version of the grparser.c file from the ISDC
-
-   - added new WCS support routines (in wcssub.c) which make it easier
-     to call Doug Mink's WCSlib routines for converting between plate
-     and sky coordinates.   The CFITSIO routines themselves never
-     call a WCSlib routine, so CFITSIO is not dependent on WCSlib.
-
-   - modified  ffopen so that if you use the extended filename
-     syntax to both select rows in a table and then bin columns into
-     a histogram, then CFITSIO will simply construct an array listing
-     the good row numbers to be used when making the histogram,
-     instead of making a whole new temporary FITS file containing
-     the selected rows.
-
-   - modified ffgphd which parses the primary array header keywords
-     when opening a file, to not choke on minor format errors in 
-     optional keywords.  Otherwise, this prevents CFITSIO from
-     even opening the file.
-
-   - changed a few more variable declarations in compress.c from global
-     to static.
-
-Version 2.027 - 12 Jan 1999
-
-   - modified the usage of the output filename specifier so that it,
-       a) gives the name of the binned image, if specified, else,
-       b) gives the name of column filtered and/or row filtered table, if 
-          specified, else
-       c) is the name for a local copy of the ftp or http file, else,
-       d) is the name for the local uncompressed version of the compressed
-          FITS file, else,
-       e) the output filename is ignored.
-
-   - fixed minor bug in ffcmps, when comparing 2 strings while using
-     a '*' wild card character.
-
-   - fixed bug in ftgthd that affected cases where the template string
-     started with a minus sign and contained 2 tokens (to rename a
-     keyword).
-
-   - added support for the HIERARCH keyword convention for reading 
-     and writing keywords longer than 8 characters or that contain
-     ASCII characters not allowed in normal FITS keywords. 
-
-   - modified the extended filename syntax to support opening images
-     that are contained in a single cell of a binary table with syntax:
-     filename.fits[extname; col_name(row_expression)]
-
-Version 2.026 - 23 Dec 1998
-
-   - modified the group parser to:
-     a) support CFITSIO_INCLUDE_FILES environment variable, which can
-     point to the location of template files, and, 
-     b) the FITS file parameter passed to the parser no longer has to point
-     to an empty file.  If there are already HDUs in the file, then the
-     parser appends new HDUs to the end of the file.
-
-   - make a small change to the drvrnet.c file to accommodate creating
-     a static version of the CFITSIO library.
-
-   - added 2 new routines to read consecutive bits as an unsigned integer 
-     from a Bit 'X' or Byte 'B' column (ffgcxui and ffgcxuk).
-
-   - modified the logic for determining histogram boundaries in ffhisto
-     to add one more bin by default, to catch values that are right on
-     the upper boundary of the histogram, or are in the last partial bin.
-
-   - modified cfitsio2.h to support the new Solaris 7 64-bit mode operating
-     system.
-
-   - Add utility routine, CFits2Unit, to the Fortran wrappers which searches
-     the gFitsFiles array for a fptr, returning its element (Fortran unit
-     number), or allocating a new element if one doesn't already
-     exists... for C calling Fortran calling CFITSIO.
-
-   - modified configure so that it does not use the compiler optimizer
-     when using gcc 2.8.x on Linux
-
-   - (re)added the fitsio.* documentation files that describe the
-     Fortran-callable FITSIO interface to the C routines.
-
-   - modified the lexical parser in eval_f.c to fix bug in null detections
-     and bug in ffsrow when nrows = 0.
-
-   - modified ffcalc so that it creates a TNULLn keyword if appropriate 
-     when a new column is created.  Also fixed detection of OVERFLOWs
-     so that it ignores null values.
-
-   - added hyperbolic trig and rounding functions to
-     the lexical parser in the eval* files.
-
-   - improved error message that gets written when the group number is
-     out of range when reading a 'random groups' array.
-
-   - added description of shared memory, grouping, and template parsing
-     error messages to ffgerr and to the User's Guide.  Moved the error
-     code definitions from drvsmem.h to fitsio.h.
-
-   - modified grparser.c to compile correctly on Alpha/OSF machines
-
-   - modified drvrnet.c to eliminate compiler warnings
-
-   - Modified Makefile.in to include targets for building all the sample
-     programs that are included with CFITSIO.
-
-Version 2.025 - 1 Dec 1998
-
-   - modified ffgphd and ffgtbp so that they ignores BLANK and TNULLn keywords
-     that  do not have a valid integer value.  Also, any error while reading
-     the BSCALE, BZERO, TSCALn, or TZEROn keywords will be ignored.  
-     Previously, CFITSIO would have simply refused to read an HDU that had 
-     such an invalid keyword.
-
-   - modified the parser in eval_f.c to accept out of order times in GTIs
-
-   - updated cfitsio_mac.sit.hqx to fix bad target parameters for Mac's
-     speed test program
-
-   - modified template parser in grparser.c to: 1) not write GRPNAME keyword
-     twice, and 2) assign correct value for EXTVERS keyword.
-
-   - fixed minor bugs in group.c; mainly would only affect users of the
-     INTEGRAL Data Access Layer.
-
-   - temporarily removed the prototype for ffiwcs from fitsio.h until
-     full WCS support is added to CFITSIO in the near future.
-
-   - modified the HTTP driver to send a User-Agent string:
-     HEASARC/CFITSIO/<version number>
-
-   - declared local variables in compress.c as 'static' to avoid
-     conflicts with other libraries.
-
-Version 2.024 - 9 Nov 1998
-
-   - added new function fits_url_type which returns the driver prefix string
-     associated with a particular FITS file pointer.
-
-Version 2.023 - 1 Nov 1998 - first full release of CFITSIO 2.0
-
-   - slightly modified the way real keyword values are formatted, to ensure
-     that it includes a decimal point.  E.g.,  '1.0E-09' instead of '1E-09'
-
-   - added new function to support template files when creating new FITS files.
-
-   - support the TCROTn WCS keyword in tables, when reading the WCS keywords.
-
-   - modified the iterator to support null values in logical columns in
-     binary tables.
-
-   - fixed bug in iterator to support null values in integer columns in
-     ASCII tables.
-
-   - changed the values for FLOATNULLVALUE and DOUBLENULLVALUE to make them
-     less likely to duplicate actual values in the data.
-
-   - fixed major bug when freeing memory in the iterator function.  It caused
-     mysterious crashes on a few platforms, but had no effect on most others.
-
-   - added support for reading IRAF format image (.imh files)
-
-   - added more error checking to return an error if the size of the FITS
-     file exceeds the largest value of a long integer (2.1 GB on 32-bit
-     platforms).
-
-   - CFITSIO now will automatically insert space for additional table rows
-     or add space to the data heap, if one writes beyond the current end
-     of the table or heap.  This prevents any HDUs which might follow
-     the current HDU from being overwritten.  It is thus no longer necessary
-     to explicitly call fits_insert_rows before writing new rows of data
-     to the FITS file.
-
-   - CFITSIO now automatically keeps track of the number of rows that have
-     been written to a FITS table, and updates the NAXIS2 keyword accordingly
-     when the table is closed.  It is no longer necessary for the application
-     program to updated NAXIS2.  
-
-   - When reading from a FITS table, CFITSIO will now return an error if the
-     application tries to read beyond the end of the table. 
-
-   - added 2 routines to get the number of rows or columns in a table.
-
-   - improved the undocumented feature that allows a '20A' column to be
-     read as though it were a '20B' column by fits_read_col_byt.  
-
-   - added overflow error checking when reading keywords.  Previously, the
-     returned value could be silently truncated to the maximum allowed value
-     for that data type.  Now an error status is returned whenever an 
-     overflow occurs.
-
-   - added new set of routines dealing with hierarchical groups of files.
-     These were provided by Don Jennings of the INTEGRAL Science Data Center.
-
-   - added new URL parsing routines.
-
-   - changed the calling sequence to ffghad (get HDU address) from
-     ffghad(fitsfile *fptr, > long *headstart, long *dataend) to
-     ffghad(fitsfile *fptr, > long *headstart, long datastart, 
-            long *dataend, int *status) 
-
-   - major modification to support opening the same FITS file more
-     than once.  Now one can open the same file multiple times and
-     read and write simultaneously to different HDUs within the file.
-     fits_open_file automatically detects if the file is already opened.
-
-   - added the ability to clobber/overwrite an existing file
-     with the same name when creating a new output file.  Just
-     precede the output file name with '!' (an exclamation mark)
-
-   - changed the ffpdat routine which writes the DATE keyword
-     to use the new 'YYYY-MM-DDThh:mm:ss' format.
-
-   - added several new routines to create or parse the new date/time
-     format string.
-
-   - changed ifdef for DECFortran in f77_wrap.h and f77_wrap1.c:
-     expanded to recognize Linux/Alpha
-
-   - added new lexical parsing routines (from Peter Wilson):
-     eval_l.c, eval_y.c, eval_f.c, eval_defs.h, and eval_tab.h.
-     These are used when doing on-the-fly table row selections.
-
-   - added new family of routines to support reading and writing
-     'unsigned int' data type values in keywords, images or tables.
-
-   - restructured all the putcol and getcol routines to provide
-     simpler and more robust support for machines which have
-     sizeof(long) = 8.  Defined a new datatype INT32BIT which is
-     always 32 bits long (platform independent) and is used internally
-     in CFITSIO when reading or writing BITPIX = 32 images or 'J'
-     columns.  This eliminated the need for specialize routines like
-     ffswaplong, ffunswaplong, and ffpacklong.
-
-   - overhauled cfileio.c (and other files) to use loadable drivers for
-     doing data I/O to different devices.  Now CFITSIO support network 
-     access to ftp:// and http:// files, and to shared memory files.
-
-   - removed the ffsmem routine and replaced it with ffomem.  This will
-     only affect software that reads an existing file in core memory.
-     (written there by some other process).
-
-   - modified all the ffgkn[] routines (get an array of keywords) so
-     that the 'nfound' parameter is = the number of keywords returned,
-     not the highest index value on the returned keywords.  This makes
-     no difference if the starting index value to look for = 1.
-     This change is not backward compatible with previous versions
-     of CFITSIO, but is the way that FITSIO behaved.
-
-   - added new error code = 1 for any application error external
-     to CFITSIO.  Also reports "unknown error status" if the
-     value doesn't match a known CFITSIO error.
-
-Version 1.42 - 30 April 1998 (included in FTOOLS 4.1 release)
-
-   - modified the routines which read a FITS float values into
-     a float array, or read FITS double values into a double array,
-     so that the array value is also explicitly set in addition
-     to setting the array of flag values, if the FITS value is a NaN.
-     This ensures that no NaN values get passed back to the calling
-     program, which can cause serious problems on some platforms (OSF).
-
-   - added calls to ffrdef at the beginning of the insert
-     or delete rows or columns routines in editcol.c to make sure
-     that CFITSIO has correctly initialized the HDU information.
-
-   - added new routine ffdrws to delete a list of rows in a table
-
-   - added ffcphd to copy the header keywords from one hdu to another
-
-   - made the anynul parameter in the ffgcl* routines optional
-     by first checking to see if the pointer is not null before
-     initializing it.
-
-   - modified ffbinit and ffainit to ignore minor format
-     errors in header keywords so that cfitsio can at least
-     move to an extension that contains illegal keywords.
-
-   - modified all the ffgcl* routines to simply return without
-     error if nelem = 0.
-
-   - added check to ffclose to check the validity of the fitsfile
-     pointer before closing it.  This should prevent program crashes
-     when someone tries to close the same file more than once.
-
-   - replaced calls to strcmp and strncmp with macros FSTRCMP and
-     FSTRNCMP in a few places to improve performance when reading
-     header keywords (suggested by Mike Noble)
-
-  Bug Fixes:
-
-   - fixed typo in macro definition of error 504 in the file fitsio.h.
-
-   - in ffopen, reserved space for 4 more characters in the input
-     file name in case a '.zip' suffix needs to be added.
-
-   - small changes to ffpclx to fix problems when writing bit (X) data
-     columns beyond the current end of file.
-
-   - fixed small bug in ffcrhd where a dummy pointer was not initialized
-
-   - initialized the dummy variable in ffgcfe and ffgcfd which
-     was causing crashes under OSF in some cases.
-
-   - increased the length of the allocated string ffgkls by 2
-     to support the case of reading a numeric keyword as a string
-     which doesn't have the enclosing quote characters.
-
-Version 1.4 - 6 Feb 1998 
-
-   - major restructuring of the CFITSIO User's Guide
-
-   - added the new 'iterator' function.  The fortran wrapper is
-     in f77_iter.c for now.
-
-   - enhanced ffcrtb so that it writes a dummy primary array
-     if none currently exists before appending the table.
-
-   - removed the ffgcl routine and replaced it with ffgcvl 
-
-   - modified ffpcnl to just take a single input null value instead
-     of an entire array of null value flags.
-
-   - modified ffcmps and ffgnxk so that, for example, the string 'rate' 
-     is not considered a match to the string 'rate2', and 'rate*'
-     is a match to the string 'rate'.
-
-   - modified ffgrsz to also work with images, in which case
-     it returns the optimum number of pixels to process at
-     one time.
-
-   - modified ffgthd to support null valued keywords
-
-   - added a new source file 'f77_wrap.c' that includes all the
-     Fortran77 wrapper routines for calling CFITSIO.  This will
-     eventually replace the Fortran FITSIO library.
-
-   - added new routines:
-     ffppn - generic write primary array with null values
-     ffpprn - write null values to primary array
-
-     ffuky - 'update' a keyword value, with any specified datatype.
-
-     ffrprt - write out report of error status and error messages
-     ffiter - apply a user function iteratively to all the rows of a table
-     ffpkyc - write complex-valued keyword
-     ffpkym - write double complex-valued keyword
-     ffpkfc - write complex-valued keyword in fixed format
-     ffpkfm - write double complex-valued keyword in fixed format
-
-     ffgkyc - read complex-valued keyword
-     ffgkym - read double complex-valued keyword
-
-     ffmkyc - modify complex-valued keyword
-     ffmkym - modify double complex-valued keyword
-     ffmkfc - modify complex-valued keyword in fixed format
-     ffmkfm - modify double complex-valued keyword in fixed format
-
-     ffukyc - update complex-valued keyword
-     ffukym - update double complex-valued keyword
-     ffukfc - update complex-valued keyword in fixed format
-     ffukfm - update double complex-valued keyword in fixed format
-
-     ffikyc - insert complex-valued keyword
-     ffikym - insert double complex-valued keyword
-     ffikfc - insert complex-valued keyword in fixed format
-     ffikfm - insert double complex-valued keyword in fixed format
-
-     ffpktp - write or modify keywords using ASCII template file
-     ffcpcl - copy a column from one table to another
-     ffcpky - copy an indexed keyword from one HDU to another
-     ffpcnl - write logical values, including nulls, to binary table
-     ffpcns - write string values,  including nulls, to table
-     ffmnhd - move to HDU with given exttype, EXTNAME and EXTVERS values
-     ffthdu - return the total number of HDUs in the file
-     ffghdt - return the type of the  CHDU
-     ffflnm - return the name of the open FITS file
-     ffflmd - return the mode of the file (READONLY or READWRITE)
-
-   - modified ffmahd and ffmrhd (to move to a new extension) so that
-     a null pointer may be given for the returned HDUTYPE argument.
-
-   - worked around a bug in the Mac CWpro2 compiler by changing all
-     the statements like "#if BYTESWAPPED == TRUE" to "if BYTESWAPPED".
-
-   - modified ffitab (insert new ASCII table) to allow tables with
-     zero number of columns
-
-   - modified Makefile.in and configure to define the -Dg77Fortran
-     CFLAGS variable on Linux platforms.  This is needed to 
-     compile the new f77_wrap.c file (which includes cfortran.h)
-
-  Bug Fixes:
-
-   - fixed small bug in ffgrz (get optimum row size) which sometimes
-     caused it to return slightly less than the maximum optimum size.
-     This bug would have done no harm to application programs.
-
-   - fixed bug in ffpclk and ffgclk to add an 'else' case
-     if size of int is not equal to size of short or size of long.
-
-   - added test to ffgkls to check if the input string is not null before
-     allocating memory for it.
-
-Version 1.32 - 21 November 1997 (internal release only)
-
-   - fixed bug in the memory deallocation (free) statements
-     in the ffopen routine in the cfileio.c file.
-
-   - modified ffgphd to tolerate minor violations of the FITS 
-     standard in the format of the XTENSION = 'IMAGE   '
-     keyword when reading FITS files.  Extra trailing spaces
-     are now allowed in the keyword value.  (FITS standard
-     will be changed so that this is not a violation).
-
-Version 1.31 - 4 November 1997 (internal release only)
-
-  Enhancements:
-
-   - added support for directly reading compressed FITS files
-     by copying the algorithms from the gzip program. This 
-     supports the Unix compress, gzip and pkzip algorithms.
-
-   - modified ffiimg, ffitab, and ffibin (insert HDUs into
-     a FITS file) so that if the inserted HDU is at the end of
-     the FITS file, then it simply appends a new empty HDU
-     and writes the required keywords.  This allows space
-     to be reserved for additional keywords in the header
-     if desired.
-
-   - added the ffchfl and ffcdfl routines to check the header and
-     data fill values, for compatibility with the Fortran FITSIO
-     library.
-
-   - added the ffgsdt routine to return the system date
-     for compatibility with the Fortran FITSIO library.
-
-   - added a diagnostic error message (written to the error stack)
-     if the routines that read data from image or column fail.
-
-   - modified ffgclb so that it simply copies the bytes from 
-     an ASCII 'nA' or 'An' format column into the user's byte
-     array.  Previously, CFITSIO would return an error when 
-     trying to read an 'A' column with ffgclb.
-
-   - modified ffpclb so that it simply copies the input array 
-     of bytes to an ASCII 'nA' or 'An' format column.
-     Previously, CFITSIO would return an error when 
-     trying to write to an 'A' column with ffpclb.
-
-  Bug Fixes:
-
-   - ffgkls was allocating one too few bytes when reading continued
-     string keyword values. 
-
-   - in testprog.c added code to properly free the memory that
-     had been allocated for string arrays.
-
-   - corrected typographical errors in the User's Guide.
-
-Version 1.30 - 11 September 1997
-
-   - major overhaul to support reading and writing FITS files
-     in memory.   The new routines fits_set_mem_buff and 
-     fits_write_mem_buff have been added to initialize and
-     copy out the memory buffer, respectively.
-
-   - added support for reading FITS files piped in on 'stdin'
-     and piped out on 'stdout'.  Just specify the file name as '-'
-     when opening or creating the FITS file.
-
-   - added support for 64-bit SGI IRIX machines.  This required
-     adding routines to pack and unpack 32-bit integers into
-     64-bit integers.
-
-   - cleaned up the code that supports G_FLOAT and IEEE_FLOAT
-     on Alpha VMS systems.  Now, the type of float is determined
-     at compile time, not run time.
-
-  Bug Fixes:
-
-   - replaced the malloc calls in the error message stack routines
-     with a static fixed size array.  The malloc's cause more
-     problems than they solved, and were prone to cause memory
-     leaks if users don't clear the error message stack when
-     closing the FITS file.
-
-   - when writing float or double keywords, test that the value
-     is not a special IEEE value such as a NaN.  Some
-     compilers would write the string 'NaN' in this case into
-     the output value string.
-
-   - fixed bug in ffiblk, to ignore EOF status return if it is
-     inserting blocks at the end of the file.
-
-   - removed the 'l' from printf format string that is constructed
-     in the ffcfmt routine.  This 'l' is non-standard and causes problems
-     with the Metrowerks compiler on a Mac.
-
-   - the default null value in images was mistakenly being set
-     equal to NO_NULL = 314, rather than NULL_UNDEFINED = 1234554321
-     in the ffgphd routine.
-
-   - check status value in ffgkls to make sure the keyword exists
-     before allocating memory for the value string.
-
-   - fixed the support for writing and reading unsigned long integer
-     keyword values in ffpky and ffgky by internally treating
-     the values as doubles.  This required changes to ffc2r and
-     ffc2d as well.
-
-   - added explicit cast to 'double' in one place in putcolb.c and
-     6 places in pubcolui.c, to get rid of warning messages issued
-     by one compiler.
-
-   - in ffbinit and ffainit, it is necessary to test that tfield > 0
-     before trying to allocate memory with calloc.  Otherwise, some
-     compilers return a null pointer which CFITSIO interprets to 
-     mean the memory allocation failed.
-
-   - had to explicitly cast the null buffer pointer to a char
-     pointer (cptr = (char *)buffer;) in 4 places in the buffers.c
-     file to satisfy a picky C++ compiler.
-
-   - changed the test for an ALPHA VMS system to see if
-     '__VMS' is defined, rather than 'VMS'.  The latter
-     is not defined by at least one C++ compiler.
-
-   - modified ffpcls so that it can write a null string to
-     a variable length string column, without going into
-     an infinite loop.
-
-   - fixed bug in ffgcfl that caused the 'next' variable to be
-     incremented twice.
-
-   - fixed bug in ffgcpr that caused it write 2x the number of
-     complex elements into the descriptor when writing to
-     a complex or double complex variable length array column.
-
-   - added call to ffrdef at the end of ffrsim to ensure that
-     the internal structures are updated to correspond to the
-     modified header keywords
-
-Version 1.25 - 7 July 1997
-
-   - improved the efficiency of the ffiblk routine, when inserting
-     more than one block into the file.
-
-   - fixed bug in ffwend that in rare instances caused the beginning
-     of the following extension to be overwritten by blank fill.
-
-   - added new routine to modify the size of an existing primary
-     array or image extension: fits_resize_img/ffrsim.
-
-   - added support for null-valued keywords, e.g., keywords that
-     have no defined value.  These keywords have an equal sign and
-     space in columns 9-10, but have not value string.  Example:
-     KEYNAME =                      / null-valued keyword
-     Support for this feature required the following changes:
-       - modified ffpsvc to return a null value string without error
-       - modified ffc2[ilrd] to return error VALUE_UNDEFINED in this case
-       - modified ffgkn[sljed] to continue reading additional keywords
-         even if one or more keywords have undefined values.
-       - added 4 new routines:  ffpkyu, ffikyu, ffmkyu, ffukyu to
-         write, insert, modify, or update an undefined keyword
-
-   - a new makefile.os2 file was added, for building CFITSIO
-     on OS/2 systems.
-
-   - modified ffgtkn so that if it finds an unexpected keyword
-     name, the returned error status = BAD_ORDER instead of
-     NOT_POS_INT.
-
-   - added 2 new routines, fits_write_key_unit/ffpunt and
-     fits_read_key_unit/ffgunt to write/read the physical
-     units of a keyword value.  These routines use a local
-     FITS convention for storing the units in square brackets
-     following the '/' comment field separator, as in:
-     VELOCITY=                   12 / [km/s] orbit speed 
-     The testprog.c program was modified to test these
-     new routines.
-
-   - in the test of Alpha OSF/1 machines in fitsio2.h,
-     change 'defined(unix)' to 'defined(__unix__)' which
-     appears to be a more robust test.
-
-   - remove test for linux environment variable from fitsio2.h
-
-Version 1.24 - 2 May 1997
-
-   - fixed bug in ffpbyt that incorrectly computed the current
-     location in the FITS file when writing > 10000 bytes.
-
-   - changed the datatype of the 'nbytes' parameter in ffpbyt 
-     from 'int' to 'long'.   Made corresponding datatype change
-     to some internal variables in ffshft.
-
-   - changed '(unsigned short *)' to '(short *)' in getcolui.c, and
-     changed '(unsigned long *)'  to '(long *)'  in getcoluj.c, to
-     work around problem with the VAX/VMS cc compiler.
-
-Version 1.23 - 24 April 1997
-
-   - modified ffcins and ffdins (in editcol.c) to simply return 
-     without error if there are no (zero) rows in the table.
-
-Version 1.22 - 18 April 1997
-
-   - fixed bug in ffgcpr that caused it to think that all values were
-     undefined in ASCII tables columns that have TNULLn = '        '
-     (i.e., the TNULLn keyword value is a string of blanks.
-
-   - fixed bug in the ffgcl[bdeijk,ui,uj] family of routines
-     when parsing a numeric value in an ASCII table.  The
-     returned values would have the decimal place shifted to
-     the left if the table field contained an explicit decimal
-     point followed by blanks.  Example:  in an F5.2 column,
-     the value '16.  ' would be returned as 0.16.  If the
-     trailing zeros were present, then cfitsio returned the
-     correct value (e.g.,  '16.00' returns 16.).
-
-   - fixed another bug in the ffgcl[bdeijk,ui,uj] family of routines
-     that caused them to misread values in an ASCII table in rows
-     following an undefined value when all the values were read
-     at once in a single call to the routine.
-
-Version 1.21 - 26 March 1997
-
-   - added general support for reading and writing unsigned integer
-     keywords, images, and binary table column values.
-
-   - fixed bug in the way the column number was used in ffgsve and
-     similar routines.  This bug caused cfitsio to read (colnum - 1)
-     rather than the desired column.
-
-   - fixed a bug in ftgkls that prevented it from reading more than one
-     continuation line of a long string keyword value.
-
-   - fixed the definition of fits_write_longwarn in longnam.h
-
-Version 1.20 - 29 Jan 1997
-
-   - when creating a binary table with variable length vector columns, if the
-     calling routine does not specify a value for the maximum length of
-     the vector (e.g.,  TFORMn = '1PE(400)')  then cfitsio will automatically
-     calculate the maximum value and append it to the TFORM value
-     when the binary table is first closed.
-
-   - added the set of routines to do coordinate system transformations
-
-   - added support for wildcards ('*', '?', and '#') in the input
-     keyword name when reading, modifying, or deleting keywords.
-
-   - added new general keyword reading routine, ffgnxk, to return
-     the next keyword whose name matches a list of template names,
-     but does not match any names on a second template list.
-
-   - modified ftgrec so that it simply moves to the beginning
-     of the header if the input keyword number = 0
-
-   - added check in ffdelt to make sure the input fits file pointer is
-     not already null
-
-   - added check in ffcopy to make sure the output HDU does not
-     already contain any keywords (it must be empty).
-
-   - modified ffgcls so that it does not test if each string column
-     value equals the null string value if the null string value
-     is longer than the width of the column.
-
-   - fixed bug in ftgtdm that caused it to fail if the TDIMn 
-     keyword did not exist in the FITS file
-
-   - modified testprog.c to include tests of keyword wildcards
-     and the WCS coordinate transformation routines.
-
-   - added a test for 'EMX' in fitsio2.h so that cfitsio builds 
-     correctly on a PC running OS/2.
-
-Version 1.11 - 04 Dec 1996
-
-   - modified the testprog.c program that is included with the
-     distribution, so that the output FITS file is identical to
-     that produced by the Fortran FITSIO test program.
-
-   - changed all instances of the 'extname' variable to 'extnm'
-     to avoid a conflict with the -Dextname switch in cfortran.h
-     on HP machines.
-
-   - in all the routines like ffi4fi1, which convert an array
-     of values to integers just prior to writing them to the FITS
-     file, the integer value is now rounded to the nearest integer
-     rather than truncated. (ffi4fi1, ffi4fi2, ffi4fi4, etc)
-
-   - changed ffgcfl (and hence ffgcl) so that the input value
-     of the logical array element is not changed if the corresponding
-     FITS value is undefined.
-
-   - in ffgacl, the returned value of TBCOL was off by 1 (too small)
-
-   - fixed the comment of EXTNAME keyword to read 'binary table'
-     instead of 'ASCII table' in the header of binary tables.
-
-Version 1.101 - 17 Nov 1996
-
-   - Made major I/O efficiency improvements by adding internal buffers
-     rather than directly reading or writing to disk.  Access to 
-     columns in binary tables is now 50 - 150 times faster.  Access to
-     FITS image is also slightly faster.
-
-   - made significant speed improvements when reading numerical data
-     in FITS ASCII tables by writing my own number parsing routines
-     rather than using the sscanf C library routine.  This change
-     requires that the -lm argument now be included when linking
-     a program that calls cfitsio (under UNIX).
-
-   - regrouped the source files into logically related sets of routines.
-     The Makefile now runs much faster since every single routine is
-     not split into a separate file.
-
-   - now use the memcpy function, rather than a 'for' loop in several
-     places for added efficiency
-
-   - redesigned the low-level binary table read and write routines
-     (ffpbytoff and ffgbytoff) for greater efficiency.
-
-   - added a new error status: 103 = too many open FITS files.
-
-   - added a 'extern "C"' statement around the function prototypes
-     in fitsio.h, to support use of cfitsio by C++ compilers.
-
-   - fixed routines for writing or reading fixed-length substrings
-     within a binary table ASCII column, with TFORM values of
-     of the form 'rAw' where 'r' is the total width of the ASCII
-     column and 'w' is the width of a substring within the column.
-
-   - no longer automatically rewrite the END card and following fill
-     values if they are already correct.
-
-   - all the 'get keyword value and comment' routines have been changed 
-     so that the comment is not returned if the input pointer is NULL.
-
-   - added new routine to return the optimum number of tables rows
-     that should be read or written at one time for optimum efficiency.
-
-   - modified the way numerical values in ASCII tables are parsed so
-     that embedded spaces in the value are ignored, and implicit
-     decimal points are now supported.   (e.g, the string '123E 12'
-     in a 'E10.2' format column will be interpreted as 1.23 * 10**12).
-
-   - modified ffpcl and ffgcl to support binary table columns of
-     all datatype (added logical, bit, complex, and double complex)
-
-   - when writing numerical data to ASCII table columns, the ffpcl_
-     routines now return an overflow error if a value is too large
-     to be expressed in the column format.
-
-   - closed small memory leak in ffpcls.
-
-   - initialized the 'incre' variable in ffgcpr to eliminate compiler warning.
-
-Version 1.04 - 17 Sept 1996
-
-   - added README.MacOS and cfitsio_mac.sit.hqx to the distribution
-     to support the Mac platforms.
-
-   - fixed bug in ffpdfl that caused an EOF error (107) when a program
-     creates a new extension that is an exact multiple of 2880 bytes long,
-     AND the program does not write a value to the last element
-     in the table or image.
-
-   - fixed bug in all the ffgsf* and ffgcv* routines which caused
-     core dumps when reading null values in a table.
-
-Version 1.03 - 20 August 1996
-
-   - added full support for reading and writing the C 'int'
-     data type.  This was a problem on Alpha/OSF where short,
-     int, and long datatypes are 2, 4, and 8 bytes long, respectively.
-
-   - cleaned up the code in the byte-swapping routines.
-
-   - renamed the file 'longname.h' to 'longnam.h' to avoid conflict
-     with a file with the same name in another unrelated package.
-
-Version 1.02 - 15 August 1996
-
-   - ffgtbp was not correctly reading the THEAP keyword, hence would
-     not correctly read variable length data in binary tables if
-     the heap was not at the default starting location (i.e., 
-     starting immediately after the fixed length table).
-
-   - now force the cbuff variable in ffpcl_ and ffgcl_ to be
-     aligned on a double word boundary.  Non-alignment can
-     cause program to crash on some systems.
-

-\`configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]
-  --libexecdir=DIR        program executables [EPREFIX/libexec]

-
-Some influential environment variables:
-  CC          C compiler command
-  CFLAGS      C compiler flags
-  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
-              nonstandard directory <lib dir>
-  LIBS        libraries to pass to the linker, e.g. -l<library>
-  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
-              you have headers in a nonstandard directory <include dir>
-  CPP         C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.
-
-Report bugs to the package provider.

-C  This is the FITSIO cookbook program that contains an annotated listing of
-C  various computer programs that read and write files in FITS format
-C  using the FITSIO subroutine interface.  These examples are
-C  working programs which users may adapt and modify for their own
-C  purposes.  This Cookbook serves as a companion to the FITSIO User's
-C  Guide that provides more complete documentation on all the
-C  available FITSIO subroutines.
-
-C  Call each subroutine in turn:
-
-      call writeimage
-      call writeascii
-      call writebintable
-      call copyhdu
-      call selectrows
-      call readheader
-      call readimage
-      call readtable
-      print *
-      print *,"All the fitsio cookbook routines ran successfully."
-
-      end
-C *************************************************************************
-      subroutine writeimage
-
-C  Create a FITS primary array containing a 2-D image
-
-      integer status,unit,blocksize,bitpix,naxis,naxes(2)
-      integer i,j,group,fpixel,nelements,array(300,200)
-      character filename*80
-      logical simple,extend
-
-C  The STATUS parameter must be initialized before using FITSIO.  A
-C  positive value of STATUS is returned whenever a serious error occurs.
-C  FITSIO uses an `inherited status' convention, which means that if a
-C  subroutine is called with a positive input value of STATUS, then the
-C  subroutine will exit immediately, preserving the status value. For 
-C  simplicity, this program only checks the status value at the end of 
-C  the program, but it is usually better practice to check the status 
-C  value more frequently.
-
-      status=0
-
-C  Name of the FITS file to be created:
-      filename='ATESTFILEZ.FITS'
-
-C  Delete the file if it already exists, so we can then recreate it.
-C  The deletefile subroutine is listed at the end of this file.
-      call deletefile(filename,status)
-
-C  Get an unused Logical Unit Number to use to open the FITS file.
-C  This routine is not required;  programmers can choose any unused
-C  unit number to open the file.
-      call ftgiou(unit,status)
-
-C  Create the new empty FITS file.  The blocksize parameter is a
-C  historical artifact and the value is ignored by FITSIO.
-      blocksize=1
-      call ftinit(unit,filename,blocksize,status)
-
-C  Initialize parameters about the FITS image.
-C  BITPIX = 16 means that the image pixels will consist of 16-bit
-C  integers.  The size of the image is given by the NAXES values. 
-C  The EXTEND = TRUE parameter indicates that the FITS file
-C  may contain extensions following the primary array.
-      simple=.true.
-      bitpix=16
-      naxis=2
-      naxes(1)=300
-      naxes(2)=200
-      extend=.true.
-
-C  Write the required header keywords to the file
-      call ftphpr(unit,simple,bitpix,naxis,naxes,0,1,extend,status)
-
-C  Initialize the values in the image with a linear ramp function
-      do j=1,naxes(2)
-          do i=1,naxes(1)
-              array(i,j)=i - 1 +j - 1
-          end do
-      end do
-
-C  Write the array to the FITS file.
-C  The last letter of the subroutine name defines the datatype of the
-C  array argument; in this case the 'J' indicates that the array has an
-C  integer*4 datatype. ('I' = I*2, 'E' = Real*4, 'D' = Real*8).
-C  The 2D array is treated as a single 1-D array with NAXIS1 * NAXIS2
-C  total number of pixels.  GROUP is seldom used parameter that should
-C  almost always be set = 1.
-      group=1
-      fpixel=1
-      nelements=naxes(1)*naxes(2)
-      call ftpprj(unit,group,fpixel,nelements,array,status)
-
-C  Write another optional keyword to the header
-C  The keyword record will look like this in the FITS file:
-C
-C  EXPOSURE=                 1500 / Total Exposure Time
-C
-      call ftpkyj(unit,'EXPOSURE',1500,'Total Exposure Time',status)
-
-C  The FITS file must always be closed before exiting the program. 
-C  Any unit numbers allocated with FTGIOU must be freed with FTFIOU.
-      call ftclos(unit, status)
-      call ftfiou(unit, status)
-
-C  Check for any errors, and if so print out error messages.
-C  The PRINTERROR subroutine is listed near the end of this file.
-      if (status .gt. 0)call printerror(status)
-      end
-C *************************************************************************
-      subroutine writeascii
-
-C  Create an ASCII table containing 3 columns and 6 rows.  For convenience,
-C  the ASCII table extension is appended to the FITS image file created 
-C  previously by the WRITEIMAGE subroutine.
-
-      integer status,unit,readwrite,blocksize,tfields,nrows,rowlen
-      integer nspace,tbcol(3),diameter(6), colnum,frow,felem
-      real density(6)
-      character filename*40,extname*16
-      character*16 ttype(3),tform(3),tunit(3),name(6)

-      data density/5.1,5.3,5.52,3.94,1.33,0.69/
-
-C  The STATUS parameter must always be initialized.
-      status=0
-
-C  Name of the FITS file to append the ASCII table to:
-      filename='ATESTFILEZ.FITS'
-
-C  Get an unused Logical Unit Number to use to open the FITS file.
-      call ftgiou(unit,status)
-
-C  Open the FITS file with write access.

-C  FITSIO usually generates an internal stack of error messages whenever
-C  an error occurs.  These messages provide much more information on the
-C  cause of the problem than can be provided by the single integer error
-C  status value.  The FTGMSG subroutine retrieves the oldest message from
-C  the stack and shifts any remaining messages on the stack down one
-C  position.  FTGMSG is called repeatedly until a blank message is
-C  returned, which indicates that the stack is empty.  Each error message
-C  may be up to 80 characters in length.  Another subroutine, called
-C  FTCMSG, is available to simply clear the whole error message stack in
-C  cases where one is not interested in the contents.

-  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
-  x^32+x^26+x^23+x^22+x^16+x^12+x^11+x^10+x^8+x^7+x^5+x^4+x^2+x+1.
-
-  Polynomials over GF(2) are represented in binary, one bit per coefficient,
-  with the lowest powers in the most significant bit.  Then adding polynomials
-  is just exclusive-or, and multiplying a polynomial by x is a right shift by
-  one.  If we call the above polynomial p, and represent a byte as the
-  polynomial q, also with the lowest power in the most significant bit (so the
-  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
-  where a mod b means the remainder after dividing a by b.
-
-  This calculation is done using the shift-register method of multiplying and
-  taking the remainder.  The register is initialized to zero, and for each
-  incoming bit, x^32 is added mod p to the register if the bit is a one (where
-  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
-  x (which is shifting right by one and adding x^32 mod p if the bit shifted
-  out is a one).  We start with the highest power (least significant bit) of
-  q and repeat for all eight bits of q.
-
-  The first table is simply the CRC of all possible eight bit values.  This is
-  all the information needed to generate CRCs on data a byte at a time for all
-  combinations of CRC register values and incoming bytes.  The remaining tables
-  allow for word-at-a-time CRC calculation for both big-endian and little-
-  endian machines, where a word is four bytes.

-/*
- *  ALGORITHM
- *
- *      The "deflation" process depends on being able to identify portions
- *      of the input text which are identical to earlier input (within a
- *      sliding window trailing behind the input currently being processed).
- *
- *      The most straightforward technique turns out to be the fastest for
- *      most input files: try all possible matches and select the longest.
- *      The key feature of this algorithm is that insertions into the string
- *      dictionary are very simple and thus fast, and deletions are avoided
- *      completely. Insertions are performed at each input character, whereas
- *      string matches are performed only when the previous match ends. So it
- *      is preferable to spend more time in matches to allow very fast string
- *      insertions and avoid deletions. The matching algorithm for small
- *      strings is inspired from that of Rabin & Karp. A brute force approach
- *      is used to find longer strings when a small match has been found.
- *      A similar algorithm is used in comic (by Jan-Mark Wams) and freeze
- *      (by Leonid Broukhis).
- *         A previous version of this file used a more sophisticated algorithm
- *      (by Fiala and Greene) which is guaranteed to run in linear amortized
- *      time, but has a larger average cost, uses more memory and is patented.
- *      However the F&G algorithm may be faster for some highly redundant
- *      files if the parameter max_chain_length (described below) is too large.
- *
- *  ACKNOWLEDGEMENTS
- *
- *      The idea of lazy evaluation of matches is due to Jan-Mark Wams, and
- *      I found it in 'freeze' written by Leonid Broukhis.
- *      Thanks to many people for bug reports and testing.

-
-   The ftp driver uses passive mode exclusivly.  If your remote system can't 
-   deal with passive mode then it'll fail.  Since Netscape Navigator uses 
-   passive mode as well there shouldn't be too many ftp servers which have
-   problems.
-
-
-   The http driver works properly with 301 and 302 redirects.  For many more 
-   gory details see http://www.w3c.org/Protocols/rfc2068/rfc2068.  The only
-   catch to the 301/302 redirects is that they have to redirect to another 
-   http:// url.  If not, things would have to change a lot in cfitsio and this
-   was thought to be too difficult.

-
-   This redirect was from apache 1.2.5 but most of the other servers produce 
-   something very similiar.  The parser for the redirects finds the first 
-   anchor <A> tag in the body and goes there.  If that wasn't what was intended
-   by the remote system then hopefully the error stack, which includes notes 
-   about the redirect will help the user fix the problem.
-
-
-
-   Root protocal doesn't have any real docs, so, the emperical docs are as 
-   follows.  
-
-   First, you must use a slightly modified rootd server.  The modifications 
-   include implimentation of the stat command which returns the size of the 
-   remote file.  Without that it's impossible for cfitsio to work properly
-   since fitsfiles don't include any information about the size of the files 
-   in the headers.  The rootd server closes the connections on any errors, 
-   including reading beyond the end of the file or seeking beyond the end 
-   of the file.  The rootd:// driver doesn't reopen a closed connection, if
-   the connection is closed you're pretty much done.
-
-   The messages are of the form
-
-   <len><opcode><optional information>
-
-   All binary information is transfered in network format, so use htonl and 
-   ntohl to convert back and forth.
-
-   <len> :== 4 byte length, in network format, the len doesn't include the
-         length of <len>
-   <opcode> :== one of the message opcodes below, 4 bytes, network format
-   <optional info> :== depends on opcode
-
-   The response is of the same form with the same opcode sent.  Success is
-   indicated by <optional info> being 0.
-
-   Root is a NFSish protocol where each read/write includes the byte
-   offset to read or write to.  As a result, seeks will always succeed
-   in the driver even if they would cause a fatal error when you try
-   to read because you're beyond the end of the file.
-
-   There is file locking on the host such that you need to possibly
-   create /usr/tmp/rootdtab on the host system.  There is one file per
-   socket connection, though the rootd daemon can support multiple
-   files open at once.
-
-   The messages are sent in the following order:
-
-   ROOTD_USER - user name, <optional info> is the user name, trailing
-   null is sent though it's not required it seems.  A ROOTD_AUTH
-   message is returned with any sort of error meaning that the user
-   name is wrong.
-
-   ROOTD_PASS - password, ones complemented, stored in <optional info>. Once
-   again the trailing null is sent.  Once again a ROOTD_AUTH message is 
-   returned
-
-   ROOTD_OPEN - <optional info> includes filename and one of
-     {create|update|read} as the file mode.  ~ seems to be dealt with
-     as the username's login directory.  A ROOTD_OPEN message is
-     returned.
-
-   Once the file is opened any of the following can be sent:
-
-   ROOTD_STAT - file status and size
-   returns a message where <optional info> is the file length in bytes
-
-   ROOTD_FLUSH - flushes the file, not sure this has any real effect
-   on the daemon since the daemon uses open/read/write/close rather
-   than the buffered fopen/fread/fwrite/fclose.
-
-   ROOTD_GET - on send <optional info> includes a text message of
-   offset and length to get.  Return is a status message first with a
-   status value, then, the raw bytes for the length that you
-   requested.  It's an error to seek or read past the end of the file,
-   and, the rootd daemon exits and won't respond anymore.  Ie, don't
-   do this.
-
-   ROOTD_PUT - on send <optional info> includes a text message of
-   offset and length to put.  Then send the raw bytes you want to
-   write.  Then recieve a status message
-
-
-   When you are finished then you send the message:
-
-   ROOTD_CLOSE - closes the file
-
-   Once the file is closed then the socket is closed.

-09-Mar-98 : initial version 1.0 released
-23-Mar-98 : shared_malloc now accepts new handle as an argument
-23-Mar-98 : shmem://0, shmem://1, etc changed to shmem://h0, etc due to bug
-            in url parser.
-10-Apr-98 : code cleanup
-13-May-99 : delayed initialization added, global table deleted on exit when
-            no shmem segments remain, and last process terminates

-     f77_wrap1.c and f77_wrap2.c have now been split into 4 files to

-     f77_wrap1.c was split into f77_wrap1.c and f77_wrap3.c, and
-     f77_wrap2.c was split into f77_wrap2.c and f77_wrap4.c:

-
-     Peter's original comments:
-
-     Together, f77_wrap1.c and f77_wrap2.c contain C wrappers for all

-     (eg, unsigned integers), a few routines prototyped in fitsio2.h,
-     which only a handful of FTOOLS use, plus a few obsolete FITSIO

-     The main exception are read/write routines ending in j (ie, long
-     data) which get redirected to C routines ending in k (ie, int
-     data). This is more consistent with the default integer type in

-
-     f77_wrap1.c and f77_wrap2.c have now been split into 4 files to
-     prevent compile-time memory errors (from expansion of compiler commands).
-     f77_wrap1.c was split into f77_wrap1.c and f77_wrap3.c, and
-     f77_wrap2.c was split into f77_wrap2.c and f77_wrap4.c:
-
-       f77_wrap1.c contains routines operating on whole files and some
-       utility routines.
-
-       f77_wrap2.c contains routines operating on primary array, image,
-       or column elements.
-
-       f77_wrap3.c contains routines operating on headers & keywords.
-
-       f77_wrap4.c contains miscellaneous routines.
-
-     Peter's original comments:
-
-     Together, f77_wrap1.c and f77_wrap2.c contain C wrappers for all
-     the CFITSIO routines prototyped in fitsio.h, except for the
-     generic datatype routines and features not supported in fortran
-     (eg, unsigned integers), a few routines prototyped in fitsio2.h,
-     which only a handful of FTOOLS use, plus a few obsolete FITSIO
-     routines not present in CFITSIO.  This file allows Fortran code
-     to use the CFITSIO library instead of the FITSIO library without
-     modification.  It also gives access to new routines not present
-     in FITSIO.  Fortran FTOOLS must continue using the old routine
-     names from FITSIO (ie, ftxxxx), but most of the C-wrappers simply
-     redirect those calls to the corresponding CFITSIO routines (ie,
-     ffxxxx), with appropriate parameter massaging where necessary.
-     The main exception are read/write routines ending in j (ie, long
-     data) which get redirected to C routines ending in k (ie, int
-     data). This is more consistent with the default integer type in
-     Fortran. f77_wrap1.c primarily holds routines operating on whole
-     files and extension headers.  f77_wrap2.c handle routines which
-     read and write the data portion, plus miscellaneous extra routines.

-
-     f77_wrap1.c and f77_wrap2.c have now been split into 4 files to
-     prevent compile-time memory errors (from expansion of compiler commands).
-     f77_wrap1.c was split into f77_wrap1.c and f77_wrap3.c, and
-     f77_wrap2.c was split into f77_wrap2.c and f77_wrap4.c:
-       
-       f77_wrap1.c contains routines operating on whole files and some 
-       utility routines.
-     
-       f77_wrap2.c contains routines operating on primary array, image, 
-       or column elements.
-
-       f77_wrap3.c contains routines operating on headers & keywords.
-
-       f77_wrap4.c contains miscellaneous routines.
-
-     Peter's original comments:
-
-     Together, f77_wrap1.c and f77_wrap2.c contain C wrappers for all
-     the CFITSIO routines prototyped in fitsio.h, except for the
-     generic datatype routines and features not supported in fortran
-     (eg, unsigned integers), a few routines prototyped in fitsio2.h,
-     which only a handful of FTOOLS use, plus a few obsolete FITSIO
-     routines not present in CFITSIO.  This file allows Fortran code
-     to use the CFITSIO library instead of the FITSIO library without
-     modification.  It also gives access to new routines not present
-     in FITSIO.  Fortran FTOOLS must continue using the old routine
-     names from FITSIO (ie, ftxxxx), but most of the C-wrappers simply
-     redirect those calls to the corresponding CFITSIO routines (ie,
-     ffxxxx), with appropriate parameter massaging where necessary.
-     The main exception are read/write routines ending in j (ie, long
-     data) which get redirected to C routines ending in k (ie, int
-     data). This is more consistent with the default integer type in
-     Fortran. f77_wrap1.c primarily holds routines operating on whole
-     files and extension headers.  f77_wrap2.c handle routines which
-     read and write the data portion, plus miscellaneous extra routines.
-

-/*  #########################################################################
-These routines to apply the H-compress compression algorithm to a 2-D Fits
-image were written by R. White at the STScI and were obtained from the STScI at
-http://www.stsci.edu/software/hcompress.html
-
-This source file is a concatination of the following sources files in the
-original distribution 
- htrans.c 
- digitize.c 
- encode.c 
- qwrite.c 
- doencode.c 
- bit_output.c 
- qtree_encode.c
-
-The following modifications have been made to the original code:
-
-  - commented out redundant "include" statements
-  - added the noutchar global variable 
-  - changed all the 'extern' declarations to 'static', since all the routines are in
-    the same source file
-  - changed the first parameter in encode (and in lower level routines from a file stream
-    to a char array
-  - modifid the encode routine to return the size of the compressed array of bytes
-  - changed calls to printf and perror to call the CFITSIO ffpmsg routine
-  - modified the mywrite routine, and lower level byte writing routines,  to copy 
-    the output bytes to a char array, instead of writing them to a file stream
-  - replace "exit" statements with "return" statements
-  - changed the function declarations to the more modern ANSI C style

-These routines to apply the H-compress decompression algorithm to a 2-D Fits
-image were written by R. White at the STScI and were obtained from the STScI at
-http://www.stsci.edu/software/hcompress.html
-
-This source file is a concatination of the following sources files in the
-original distribution 
-  hinv.c 
-  hsmooth.c 
-  undigitize.c 
-  decode.c 
-  dodecode.c 
-  qtree_decode.c 
-  qread.c 
-  bit_input.c
-
-
-The following modifications have been made to the original code:
-
-  - commented out redundant "include" statements
-  - added the nextchar global variable 
-  - changed all the 'extern' declarations to 'static', since all the routines are in
-    the same source file
-  - changed the first parameter in decode (and in lower level routines from a file stream
-    to a char array
-  - modified the myread routine, and lower level byte reading routines,  to copy 
-    the input bytes to a char array, instead of reading them from a file stream
-  - changed the function declarations to the more modern ANSI C style
-  - changed calls to printf and perror to call the CFITSIO ffpmsg routine
-  - replace "exit" statements with "return" statements

-Translate a keyword name to a new name, based on a set of patterns.
-The user passes an array of patterns to be matched.  Input pattern
-number i is pattern[i][0], and output pattern number i is
-pattern[i][1].  Keywords are matched against the input patterns.  If a
-match is found then the keyword is re-written according to the output
-pattern.
-
-Order is important.  The first match is accepted.  The fastest match
-will be made when templates with the same first character are grouped
-together.
-
-Several characters have special meanings:
-
-     i,j - single digits, preserved in output template
-     n - column number of one or more digits, preserved in output template
-     m - generic number of one or more digits, preserved in output template
-     a - coordinate designator, preserved in output template
-     # - number of one or more digits
-     ? - any character
-     * - only allowed in first character position, to match all
-         keywords; only useful as last pattern in the list
-
-i, j, n, and m are returned by the routine.
-
-For example, the input pattern "iCTYPn" will match "1CTYP5" (if n_value
-is 5); the output pattern "CTYPEi" will be re-written as "CTYPE1".
-Notice that "i" is preserved.
-
-The following output patterns are special
-
-Special output pattern characters:
-
-    "-" - do not copy a keyword that matches the corresponding input pattern
-
-    "+" - copy the input unchanged
-
-The inrec string could be just the 8-char keyword name, or the entire 
-80-char header record.  Characters 9 = 80 in the input string simply get
-appended to the translated keyword name.
-
-If n_range = 0, then only keywords with 'n' equal to n_value will be 
-considered as a pattern match.  If n_range = +1, then all values of 
-'n' greater than or equal to n_value will be a match, and if -1, 
-then values of 'n' less than or equal to n_value will match.

-Translate a keyword name to a new name, based on a set of patterns.
-The user passes an array of patterns to be matched.  Input pattern
-number i is pattern[i][0], and output pattern number i is
-pattern[i][1].  Keywords are matched against the input patterns.  If a
-match is found then the keyword is re-written according to the output
-pattern.
-
-Order is important.  The first match is accepted.  The fastest match
-will be made when templates with the same first character are grouped
-together.
-
-Several characters have special meanings:
-
-     i,j - single digits, preserved in output template
-     n, m - column number of one or more digits, preserved in output template
-     k - generic number of one or more digits, preserved in output template
-     a - coordinate designator, preserved in output template
-     # - number of one or more digits
-     ? - any character
-     * - only allowed in first character position, to match all
-         keywords; only useful as last pattern in the list
-
-i, j, n, and m are returned by the routine.
-
-For example, the input pattern "iCTYPn" will match "1CTYP5" (if n_value
-is 5); the output pattern "CTYPEi" will be re-written as "CTYPE1".
-Notice that "i" is preserved.
-
-The following output patterns are special
-
-Special output pattern characters:
-
-    "-" - do not copy a keyword that matches the corresponding input pattern
-
-    "+" - copy the input unchanged
-
-The inrec string could be just the 8-char keyword name, or the entire 
-80-char header record.  Characters 9 = 80 in the input string simply get
-appended to the translated keyword name.
-
-If n_range = 0, then only keywords with 'n' equal to n_value will be 
-considered as a pattern match.  If n_range = +1, then all values of 
-'n' greater than or equal to n_value will be a match, and if -1, 
-then values of 'n' less than or equal to n_value will match.

-*I.  Introduction
-
-This document describes the Fortran-callable subroutine interface that
-is provided as part of the CFITSIO library (which is written in ANSI
-C).  This is a companion document to the CFITSIO User's Guide which
-should be consulted for further information about the underlying
-CFITSIO library.  In the remainder of this document, the terms FITSIO
-and CFITSIO are interchangeable and refer to the same library.
-
-FITSIO/CFITSIO is a machine-independent library of routines for reading
-and writing data files in the FITS (Flexible Image Transport System)
-data format.  It can also read IRAF format image files and raw binary
-data arrays by converting them on the fly into a virtual FITS format
-file.  This library was written to provide a powerful yet simple
-interface for accessing FITS files which will run on most commonly used
-computers and workstations. FITSIO supports all the features described
-in the official NOST definition of the FITS format and can read and
-write all the currently defined types of extensions, including ASCII
-tables (TABLE), Binary tables (BINTABLE) and IMAGE extensions. The
-FITSIO subroutines insulate the programmer from having to deal with the
-complicated formatting details in the FITS file, however, it is assumed
-that users have a general knowledge about the structure and usage of
-FITS files.
-
-The CFITSIO package was initially developed by the HEASARC (High Energy
-Astrophysics Science Archive Research Center) at the NASA Goddard Space
-Flight Center to convert various existing and newly acquired
-astronomical data sets into FITS format and to further analyze data
-already in FITS format.  New features continue to be added to CFITSIO
-in large part due to contributions of ideas or actual code from users
-of the package.  The Integral Science Data Center in Switzerland, and
-the XMM/ESTEC project in The Netherlands made especially significant
-contributions that resulted in many of the new features that appeared
-in v2.0 of CFITSIO.
-
-The latest version of the CFITSIO source code, documentation, and
-example programs are available on the World-Wide Web or via anonymous
-ftp from:

-*II.  Creating FITSIO/CFITSIO 
- 
-**A.  Building the Library
-
-To use the FITSIO subroutines one must first build the CFITSIO library,
-which requires a C compiler. gcc is ideal, or most other ANSI-C
-compilers will also work.  The CFITSIO code is contained in about 40 C
-source files (*.c) and header files (*.h). On VAX/VMS systems 2
-assembly-code files (vmsieeed.mar and vmsieeer.mar) are also needed.
-
-The Fortran interface subroutines to the C CFITSIO routines are located
-in the f77\_wrap1.c, through f77\_wrap4.c files.  These are relatively simple
-'wrappers' that translate the arguments in the Fortran subroutine into
-the appropriate format for the corresponding C routine.  This
-translation is performed transparently to the user by a set of C macros
-located in the cfortran.h file.  Unfortunately cfortran.h does not
-support every combination of C and Fortran compilers so the Fortran
-interface is not supported on all platforms. (see further notes below).  
-
-A standard combination of C and Fortran compilers will be assumed by
-default, but one may also specify a particular Fortran compiler by
-doing:
--
- >  setenv CFLAGS -DcompilerName=1
--
-(where 'compilerName' is the name of the compiler) before running 
-the configure command.  The currently recognized compiler
-names are: 
--
- g77Fortran
- IBMR2Fortran
- CLIPPERFortran
- pgiFortran
- NAGf90Fortran
- f2cFortran
- hpuxFortran
- apolloFortran
- sunFortran
- CRAYFortran
- mipsFortran
- DECFortran
- vmsFortran
- CONVEXFortran
- PowerStationFortran
- AbsoftUNIXFortran
- AbsoftProFortran
- SXFortran
--
-Alternatively, one may edit the CFLAGS line in the Makefile to add the
-'-DcompilerName' flag after running the './configure' command.
-
-The CFITSIO library is built on Unix systems by typing:
--
- >  ./configure [--prefix=/target/installation/path]
-                [--enable-sse2] [--enable-ssse3]
- >  make          (or  'make shared')
- >  make install  (this step is optional)
--
-at the operating system prompt.  The configure command customizes the
-Makefile for the particular system, then the `make' command compiles the
-source files and builds the library.  Type `./configure' and not simply
-`configure' to ensure that the configure script in the current directory
-is run and not some other system-wide configure script.  The optional
-'prefix' argument to configure gives the path to the directory where
-the CFITSIO library and include files should be installed via the later
-'make install' command. For example,
--
-   > ./configure --prefix=/usr1/local
--
-will cause the 'make install' command to copy the CFITSIO libcfitsio file 
-to /usr1/local/lib and the necessary include files to /usr1/local/include
-(assuming of course that the  process has permission to write to these 
-directories).
-
-The optional --enable-sse2 and --enable-ssse3 flags will cause configure to 
-attempt to build CFITSIO using faster byte-swapping algorithms.
-See the "Optimizing Programs" section of this manual for
-more information about these options.
-
-By default, the Makefile will be configured to build the set of Fortran-callable
-wrapper routines whose calling sequences are described later in this
-document.
-
-The 'make shared' option builds a shared or dynamic version of the
-CFITSIO library.  When using the shared library the executable code is
-not copied into your program at link time and instead the program
-locates the necessary library code at run time, normally through
-LD\_LIBRARY\_PATH or some other method. The advantages of using a shared
-library are:
--
-   1.  Less disk space if you build more than 1 program
-   2.  Less memory if more than one copy of a program using the shared
-       library is running at the same time since the system is smart
-       enough to share copies of the shared library at run time.
-   3.  Possibly easier maintenance since a new version of the shared
-       library can be installed without relinking all the software
-       that uses it (as long as the subroutine names and calling
-       sequences remain unchanged).
-   4.  No run-time penalty.
--
-The disadvantages are:
--
-   1. More hassle at runtime.  You have to either build the programs
-      specially or have LD_LIBRARY_PATH set right.
-   2. There may be a slight start up penalty, depending on where you are
-      reading the shared library and the program from and if your CPU is
-      either really slow or really heavily loaded.
--
-
-On HP/UX systems, the environment variable CFLAGS should be set
-to -Ae before running configure to enable "extended ANSI" features.
-
-It may not be possible to statically link programs that use CFITSIO on
-some platforms (namely, on Solaris 2.6) due to the network drivers
-(which provide FTP and HTTP access to FITS files).  It is possible to
-make both a dynamic and a static version of the CFITSIO library, but
-network file access will not be possible using the static version. 
-
-On VAX/VMS and ALPHA/VMS systems the make\_gfloat.com command file may
-be executed to build the cfitsio.olb object library using the default
-G-floating point option for double variables.  The make\_dfloat.com and
-make\_ieee.com files may be used instead to build the library with the
-other floating point options. Note that the getcwd function that is
-used in the group.c module may require that programs using CFITSIO be
-linked with the ALPHA\$LIBRARY:VAXCRTL.OLB library.  See the example
-link line in the next section of this document.
-
-On Windows IBM-PC type platforms the situation is more complicated
-because of the wide variety of Fortran compilers that are available and
-because of the inherent complexities of calling the CFITSIO C routines
-from Fortran.  Two different versions of the CFITSIO dll library are
-available, compiled with the Borland C++ compiler and the Microsoft
-Visual C++ compiler, respectively, in the files
-cfitsiodll\_2xxx\_borland.zip and cfitsiodll\_3xxx\_vcc.zip, where
-'3xxx' represents the current release number.  Both these dll libraries
-contain a set of Fortran wrapper routines which may be compatible with
-some, but probably not all, available Fortran compilers.  To test if
-they are compatible, compile the program testf77.f and try linking to
-these dll libraries.  If these libraries do not work with a particular
-Fortran compiler, then there are 2 possible solutions.  The first
-solution would be to modify the file cfortran.h for that particular
-combination of C and Fortran compilers, and then rebuild the CFITSIO
-dll library.  This will require, however, a some expertise in
-mixed language programming.
-The other solution is to use the older v5.03 Fortran-77 implementation
-of FITSIO that is still available from the FITSIO web-site.  This
-version is no longer supported, but it does provide the basic functions
-for reading and writing FITS files and should be compatible with most
-Fortran compilers.
-
-CFITSIO has currently been tested on the following platforms:
--
-  OPERATING SYSTEM           COMPILER
-   Sun OS                     gcc and cc (3.0.1)
-   Sun Solaris                gcc and cc
-   Silicon Graphics IRIX      gcc and cc
-   Silicon Graphics IRIX64    MIPS
-   Dec Alpha OSF/1            gcc and cc
-   DECstation  Ultrix         gcc
-   Dec Alpha OpenVMS          cc 
-   DEC VAX/VMS                gcc and cc
-   HP-UX                      gcc
-   IBM AIX                    gcc
-   Linux                      gcc
-   MkLinux                    DR3
-   Windows 95/98/NT           Borland C++ V4.5
-   Windows 95/98/NT/ME/XP     Microsoft/Compaq Visual C++ v5.0, v6.0
-   Windows 95/98/NT           Cygwin gcc
-   OS/2                       gcc + EMX
-   MacOS 7.1 or greater       Metrowerks 10.+
--
-CFITSIO will probably run on most other Unix platforms.  Cray
-supercomputers are currently not supported.
-
-**B.  Testing the Library
- 
-The CFITSIO library should be tested by building and running
-the testprog.c program that is included with the release. 
-On Unix systems type:
--
-    % make testprog
-    % testprog > testprog.lis
-    % diff testprog.lis testprog.out
-    % cmp testprog.fit testprog.std
--
- On VMS systems,
-(assuming cc is the name of the C compiler command), type:
--
-    $ cc testprog.c
-    $ link testprog, cfitsio/lib, alpha$library:vaxcrtl/lib
-    $ run testprog
--
-The testprog program should produce a FITS file called `testprog.fit'
-that is identical to the `testprog.std' FITS file included with this
-release.  The diagnostic messages (which were piped to the file
-testprog.lis in the Unix example) should be identical to the listing
-contained in the file testprog.out.  The 'diff' and 'cmp' commands
-shown above should not report any differences in the files.  (There
-may be some minor formatting differences, such as the presence or
-absence of leading zeros, or 3 digit exponents in numbers,
-which can be ignored).
-
-The Fortran wrappers in CFITSIO may be tested with the testf77
-program.  On Unix systems the fortran compilation and link command
-may be called 'f77' or 'g77', depending on the system.
--
-   % f77 -o testf77 testf77.f -L. -lcfitsio -lnsl -lsocket  
- or
-   % f77 -f -o testf77 testf77.f -L. -lcfitsio    (under SUN O/S)
- or
-   % f77 -o testf77 testf77.f -Wl,-L. -lcfitsio -lm -lnsl -lsocket (HP/UX)
- or
-   % g77 -o testf77 -s testf77.f -lcfitsio -lcc_dynamic -lncurses (Mac OS-X)
-
-   % testf77 > testf77.lis
-   % diff testf77.lis testf77.out
-   % cmp testf77.fit testf77.std
--
-On machines running SUN O/S, Fortran programs must be compiled with the
-'-f' option to force double precision variables to be aligned on 8-byte
-boundaries to make the fortran-declared variables compatible with C.  A
-similar compiler option may be required on other platforms.  Failing to
-use this option may cause the program to crash on FITSIO routines that
-read or write double precision variables.
-
-On Windows platforms, linking Fortran programs with a C library 
-often depends on the particular compilers involved.  Some users have 
-found the following commands work when using the Intel Fortran compiler:
--
-ifort /libs.dll cfitsio.lib /MD testf77.f /Gm
-
-or possibly,
-
-ifort /libs:dll cfitsio.lib /MD /fpp /extfpp:cfortran.h,fitsio.h 
-    /iface:cvf testf77.f
--
-Also note that on some systems the output listing of the testf77
-program may differ slightly from the testf77.std template if leading
-zeros are not printed by default before the decimal point when using F
-format.
-
-A few other utility  programs are included with CFITSIO: 
--
-    speed - measures the maximum throughput (in MB per second)
-              for writing and reading FITS files with CFITSIO
-
-    listhead - lists all the header keywords in any FITS file
-
-    fitscopy - copies any FITS file (especially useful in conjunction
-                 with the CFITSIO's extended input filename syntax)
-
-    cookbook - a sample program that performs common read and
-                 write operations on a FITS file.
-
-    iter_a, iter_b, iter_c - examples of the CFITSIO iterator routine
--
-
-The first 4 of these utility programs can be compiled and linked by typing
--
-   %  make program_name
--
-
-**C.  Linking Programs with FITSIO
-
-When linking applications software with the FITSIO library, several system libraries usually need to be specified on the link command line.  On 
-Unix systems, the most reliable way to determine what libraries are required
-is to type 'make testprog' and see what libraries the configure script has 
-added.  The typical libraries that may need to be added are -lm (the math 
-library) and -lnsl and -lsocket (needed only for FTP and HTTP file access).
-These latter 2 libraries are not needed on VMS and Windows platforms, 
-because FTP file access is not currently supported on those platforms.
- 
-Note that when upgrading to a newer version of CFITSIO it is usually
-necessary to recompile, as well as relink, the programs that use CFITSIO,
-because the definitions in fitsio.h often change.
- 
-**D.  Getting Started with FITSIO
-
-In order to effectively use the FITSIO library as quickly as possible,
-it is recommended that new users follow these steps:
-
-1.  Read the following `FITS Primer' chapter for a brief
-overview of the structure of FITS files.  This is especially important
-for users who have not previously dealt with the FITS table and image
-extensions.
-
-2.  Write a simple program to read or write a FITS file using the Basic
-Interface routines. 
-
-3.  Refer to the cookbook.f program that is included with this release
-for examples of routines that perform various common FITS file
-operations.
-
-4. Read Chapters 4 and 5 to become familiar with the conventions and
-advanced features of the FITSIO interface.
-
-5.  Scan through the more extensive set of routines that are provided
-in the `Advanced Interface'.  These routines perform more specialized
-functions than are provided by the Basic Interface routines.
-
-**E.  Example Program
-
-The following listing shows an example of how to use the FITSIO
-routines in a Fortran program.  Refer to the cookbook.f program that
-is included with the FITSIO distribution for examples of other
-FITS programs.

-**G.  Acknowledgments
-
-The development of many of the powerful features in CFITSIO was made
-possible through collaborations with many people or organizations from
-around the world.  The following, in particular, have made especially
-significant contributions:
-
-Programmers from the Integral Science Data Center, Switzerland (namely,
-Jurek Borkowski, Bruce O'Neel, and Don Jennings), designed the concept
-for the plug-in I/O drivers that was introduced with CFITSIO 2.0.  The
-use of `drivers' greatly simplified  the low-level I/O, which in turn
-made other new features in CFITSIO (e.g., support for compressed FITS
-files and support for IRAF format image files) much easier to
-implement.  Jurek Borkowski wrote the Shared Memory driver, and Bruce
-O'Neel wrote the drivers for accessing FITS files over the network
-using the FTP, HTTP, and ROOT protocols.
-
-The ISDC also provided the template parsing routines (written by Jurek
-Borkowski) and the hierarchical grouping routines (written by Don
-Jennings).  The ISDC DAL (Data Access Layer) routines are layered on
-top of CFITSIO and make extensive use of these features.
-
-Uwe Lammers (XMM/ESA/ESTEC, The Netherlands) designed the
-high-performance lexical parsing algorithm that is used to do
-on-the-fly filtering of FITS tables.  This algorithm essentially
-pre-compiles the user-supplied selection expression into a form that
-can be rapidly evaluated for each row.  Peter Wilson (RSTX, NASA/GSFC)
-then wrote the parsing routines used by CFITSIO based on Lammers'
-design, combined with other techniques such as the CFITSIO iterator
-routine to further enhance the data processing throughput.  This effort
-also benefited from a much earlier lexical parsing routine that was
-developed by Kent Blackburn (NASA/GSFC). More recently, Craig Markwardt
-(NASA/GSFC) implemented additional functions (median, average, stddev)
-and other enhancements to the lexical parser.
-
-The CFITSIO iterator function is loosely based on similar ideas
-developed for the XMM Data Access Layer.
-
-Peter Wilson (RSTX, NASA/GSFC) wrote the complete set of
-Fortran-callable wrappers for all the CFITSIO routines, which in turn
-rely on the CFORTRAN macro developed by Burkhard Burow.
-
-The syntax used by CFITSIO for filtering or binning input FITS files is
-based on ideas developed for the AXAF Science Center Data Model by
-Jonathan McDowell, Antonella Fruscione, Aneta Siemiginowska and Bill
-Joye. See http://heasarc.gsfc.nasa.gov/docs/journal/axaf7.html for
-further description of the AXAF Data Model.
-
-The file decompression code were taken directly from the gzip (GNU zip)
-program developed by Jean-loup Gailly and others.
-
-Doug Mink, SAO, provided the routines for converting IRAF format 
-images into FITS format.
-
-Martin Reinecke (Max Planck Institute, Garching)) provided the modifications to 
-cfortran.h that are necessary to support 64-bit integer values when calling 
-C routines from fortran programs.  The cfortran.h macros were originally developed 
-by Burkhard Burow (CERN).
-
-Julian Taylor (ESO, Garching) provided the fast byte-swapping algorithms
-that use the SSE2 and SSSE3 machine instructions available on x86\_64 CPUs.
-
-In addition, many other people have made valuable contributions to the
-development of CFITSIO.  These include (with apologies to others that may
-have inadvertently been omitted):

-*III.  A FITS Primer
-
-This section gives a brief overview of the structure of FITS files.
-Users should refer to the documentation available from the NOST, as
-described in the introduction, for more detailed information on FITS
-formats.
-
-FITS was first developed in the late 1970's as a standard data
-interchange format between various astronomical observatories.  Since
-then FITS has become the defacto standard data format supported by most
-astronomical data analysis software packages.  
-
-A FITS file consists of one or more Header + Data Units (HDUs), where
-the first HDU is called the `Primary HDU', or `Primary Array'.  The
-primary array contains an N-dimensional array of pixels, such as a 1-D
-spectrum, a 2-D image, or a 3-D data cube.  Six different primary
-datatypes are supported: Unsigned 8-bit bytes, 16, 32, and 64-bit signed
-integers, and 32 and 64-bit floating point reals.  FITS also has a
-convention for storing unsigned integers (see the later
-section entitled `Unsigned Integers' for more details). The primary HDU
-may also consist of only a header with a null array containing no
-data pixels.
-
-Any number of additional HDUs may follow the primary array; these
-additional HDUs are called FITS `extensions'.  There are currently 3
-types of extensions defined by the FITS standard:
-
-\begin{itemize}
-\item
-  Image Extension - a N-dimensional array of pixels, like in a primary array
-\item
-  ASCII Table Extension - rows and columns of data in ASCII character format
-\item
-  Binary Table Extension - rows and columns of data in binary representation
-\end{itemize}
-
-In each case the HDU consists of an ASCII Header Unit followed by an optional
-Data Unit.  For historical reasons, each Header or Data unit must be an
-exact multiple of 2880 8-bit bytes long.  Any unused space is padded
-with fill characters (ASCII blanks or zeros).
-
-Each Header Unit consists of any number of 80-character keyword records
-or `card images' which have the general form:
--
-  KEYNAME = value / comment string
-  NULLKEY =       / comment: This keyword has no value
--
-The keyword names may be up to 8 characters long and can only contain
-uppercase letters, the digits 0-9, the hyphen, and the underscore
-character. The keyword name is (usually) followed by an equals sign and
-a space character (= ) in columns 9 - 10 of the record, followed by the
-value of the keyword which may be either an integer, a floating point
-number, a character string (enclosed in single quotes), or a boolean
-value (the letter T or F).   A keyword may also have a null or undefined
-value if there is no specified value string, as in the second example.
-
-The last keyword in the header is always the `END' keyword which has no
-value or comment fields. There are many rules governing the exact
-format of a keyword record (see the NOST FITS Standard) so it is better
-to rely on standard interface software like FITSIO to correctly
-construct or to parse the keyword records rather than try to deal
-directly with the raw FITS formats.
-
-Each Header Unit begins with a series of required keywords which depend
-on the type of HDU.  These required keywords specify the size and
-format of the following Data Unit.  The header may contain other
-optional keywords to describe other aspects of the data, such as the
-units or scaling values.  Other COMMENT or HISTORY keywords are also
-frequently added to further document the data file.
-
-The optional Data Unit immediately follows the last 2880-byte block in
-the Header Unit.  Some HDUs do not have a Data Unit and only consist of
-the Header Unit.
-
-If there is more than one HDU in the FITS file, then the Header Unit of
-the next HDU immediately follows the last 2880-byte block of the
-previous Data Unit (or Header Unit if there is no Data Unit).
-
-The main required keywords in FITS primary arrays or image extensions are:
-\begin{itemize}
-\item
-BITPIX -- defines the datatype of the array: 8, 16, 32, 64, -32, -64 for
-unsigned 8--bit byte, 16--bit signed integer, 32--bit signed integer,
-64--bit signed integer,
-32--bit IEEE floating point, and 64--bit IEEE double precision floating
-point, respectively.
-\item
-NAXIS --  the number of dimensions in the array, usually 0, 1, 2, 3, or 4.
-\item
-NAXISn -- (n ranges from 1 to NAXIS) defines the size of each dimension.
-\end{itemize}
-
-FITS tables start with the keyword XTENSION = `TABLE' (for ASCII
-tables) or XTENSION = `BINTABLE' (for binary tables) and have the
-following main keywords:
-\begin{itemize}
-\item
-TFIELDS -- number of fields or columns in the table
-\item
-NAXIS2 -- number of rows in the table
-\item
-TTYPEn -- for each column (n ranges from 1 to TFIELDS) gives the
-name of the column
-\item
-TFORMn -- the datatype of the column
-\item
-TUNITn -- the physical units of the column (optional)
-\end{itemize}

-*V.  FITSIO Conventions and Guidelines
-
-**A.  CFITSIO Size Limitations
-
-CFITSIO places few restrictions on the size of FITS files that it
-reads or writes.  There are a few limits, however, which may affect
-some extreme cases:
-
-1.  The maximum number of FITS files that may be simultaneously opened
-by CFITSIO is set by NMAXFILES as defined in fitsio2.h.  It is currently
-set = 300 by default.  CFITSIO will allocate about 80 * NMAXFILES bytes
-of memory for internal use.  Note that the underlying C compiler or
-operating system, may have a smaller limit on the number of opened files.
-The C symbolic constant FOPEN\_MAX is intended to define the maximum
-number of files that may open at once (including any other text or
-binary files that may be open, not just FITS files).  On some systems it
-has been found that gcc supports a maximum of 255 opened files.
-
-2.  By default, CFITSIO can handle FITS files up to 2.1 GB in size (2**31
-bytes).  This file size limit is often imposed by 32-bit operating
-systems.  More recently, as 64-bit operating systems become more common, an
-industry-wide standard (at least on Unix systems) has been developed to
-support larger sized files (see http://ftp.sas.com/standards/large.file/). 
-Starting with version 2.1 of CFITSIO, larger FITS files up to 6 terabytes
-in size may be read and written on supported platforms.  In order
-to support these larger files, CFITSIO must be compiled with the
-'-D\_LARGEFILE\_SOURCE' and `-D\_FILE\_OFFSET\_BITS=64' compiler flags. 
-Some platforms may also require the `-D\_LARGE\_FILES' compiler flag.
- This causes the compiler to allocate 8-bytes instead of
-4-bytes for the `off\_t' datatype which is used to store file offset
-positions.  It appears that in most cases it is not necessary to
-also include these compiler flags when compiling programs that link to
-the CFITSIO library.
-
-If CFITSIO is compiled with the -D\_LARGEFILE\_SOURCE 
-and -D\_FILE\_OFFSET\_BITS=64 flags on a
-platform that supports large files, then it can read and write FITS
-files that contain up to 2**31 2880-byte FITS records, or approximately
-6 terabytes in size.  It is still required that the value of the NAXISn
-and PCOUNT keywords in each extension be within the range of a signed
-4-byte integer (max value = 2,147,483,648).  Thus, each dimension of an
-image (given by the NAXISn keywords), the total width of a table
-(NAXIS1 keyword), the number of rows in a table (NAXIS2 keyword), and
-the total size of the variable-length array heap in binary tables
-(PCOUNT keyword) must be less than this limit.
-
-Currently, support for large files within CFITSIO has been tested
-on the Linux, Solaris, and IBM AIX operating systems.
-
-**B.  Multiple Access to the Same FITS File
-
-CFITSIO supports simultaneous read and write access to multiple HDUs in
-the same FITS file.  Thus, one can open the same FITS file twice within
-a single program and move to 2 different HDUs in the file, and then
-read and write data or keywords to the 2 extensions just as if one were
-accessing 2 completely separate FITS files.   Since in general it is
-not possible to physically open the same file twice and then expect to
-be able to simultaneously (or in alternating succession) write to 2
-different locations in the file, CFITSIO recognizes when the file to be
-opened (in the call to fits\_open\_file) has already been opened and
-instead of actually opening the file again, just logically links the
-new file to the old file.  (This only applies if the file is opened
-more than once within the same program, and does not prevent the same
-file from being simultaneously opened by more than one program).  Then
-before CFITSIO reads or writes to either (logical) file, it makes sure
-that any modifications made to the other file have been completely
-flushed from the internal buffers to the file.  Thus, in principle, one
-could open a file twice, in one case pointing to the first extension
-and in the other pointing to the 2nd extension and then write data to
-both extensions, in any order, without danger of corrupting the file,
-There may be some efficiency penalties in doing this however, since
-CFITSIO has to flush all the internal buffers related to one file
-before switching to the  other, so it would still be prudent to
-minimize the number of times one switches back and forth between doing
-I/O to different HDUs in the same file.
-
-**C.  Current Header Data Unit (CHDU)
-
-In general, a FITS file can contain multiple Header Data Units, also
-called extensions.  CFITSIO only operates within one HDU at any given
-time, and the currently selected HDU is called the Current Header Data
-Unit (CHDU).  When a FITS file is first created or opened the CHDU is
-automatically defined to be the first HDU (i.e., the primary array).
-CFITSIO routines are provided to move to and open any other existing
-HDU within the FITS file or to append or insert a new HDU in the FITS
-file which then becomes the CHDU.
-
-**D.  Subroutine Names
-
-All FITSIO subroutine names begin with the letters 'ft' to distinguish
-them from other subroutines and are 5 or 6 characters long. Users should
-not name their own subroutines beginning with 'ft' to avoid conflicts.
-(The SPP interface routines all begin with 'fs'). Subroutines which read
-or get information from the FITS file have names beginning with
-'ftg...'. Subroutines which write or put information into the FITS file
-have names beginning with 'ftp...'.
-
-**E.  Subroutine Families and Datatypes
-
-Many of the subroutines come in families which differ only in the
-datatype of the associated parameter(s) .  The datatype of these
-subroutines is indicated by the last letter of the subroutine name
-(e.g., 'j' in 'ftpkyj') as follows:
--
-        x - bit 
-        b - character*1 (unsigned byte)  
-        i - short integer (I*2)
-        j - integer (I*4, 32-bit integer)
-        k - long long integer (I*8, 64-bit integer)
-        e - real exponential floating point (R*4)
-        f - real fixed-format floating point (R*4)
-        d - double precision real floating-point (R*8)
-        g - double precision fixed-format floating point (R*8)
-        c - complex reals (pairs of R*4 values)
-        m - double precision complex (pairs of R*8 values)
-        l - logical (L*4)
-        s - character string
--
-
-When dealing with the FITS byte datatype, it is important to remember
-that the raw values (before any scaling by the BSCALE and BZERO, or
-TSCALn and TZEROn keyword values) in byte arrays (BITPIX = 8) or byte
-columns (TFORMn = 'B') are interpreted as unsigned bytes with values
-ranging from 0 to 255. Some Fortran compilers support a non-standard
-byte datatype such as INTEGER*1, LOGICAL*1, or BYTE, which can sometimes
-be used instead of CHARACTER*1 variables. Many machines permit passing a
-numeric datatype (such as INTEGER*1) to the FITSIO subroutines which are
-expecting a CHARACTER*1 datatype, but this technically violates the
-Fortran-77 standard and is not supported on all machines (e.g., on a VAX/VMS
-machine one must use the VAX-specific \%DESCR function).
-
-One feature of the CFITSIO routines is that they can operate on a `X'
-(bit) column in a binary table as though it were a `B' (byte) column.
-For example a `11X' datatype column can be interpreted the same as a
-`2B' column (i.e., 2 unsigned 8-bit bytes).  In some instances, it can
-be more efficient to read and write whole bytes at a time, rather than
-reading or writing each individual bit.
-
-The double precision complex datatype is not a standard Fortran-77
-datatype.  If a particular Fortran compiler does not directly support
-this datatype,  then one may instead pass an array of pairs of double
-precision values to these subroutines.  The first  value in each pair
-is the real part, and the second is the imaginary part.
-
-**F.  Implicit Data Type Conversion
-
-The FITSIO routines that read and write numerical data can perform
-implicit data type conversion.  This means that the data type of the
-variable or array in the program does not need to be the same as the
-data type of the value in the FITS file.  Data type conversion is
-supported for numerical and string data types (if the string contains a
-valid number enclosed in quotes) when reading a FITS header keyword
-value and for numeric values when reading or writing values in the
-primary array or a table column.  CFITSIO returns status =
-NUM\_OVERFLOW  if the converted data value exceeds the range of the
-output data type.  Implicit data type conversion is not supported
-within binary tables for string, logical, complex, or double complex
-data types.
-
-In addition, any table column may be read as if it contained string values.
-In the case of numeric columns the returned string will be formatted
-using the TDISPn display format if it exists.
-
-**G.  Data Scaling
-
-When reading numerical data values in the primary array or a
-table column, the values will be scaled automatically by the BSCALE and
-BZERO (or TSCALn and TZEROn) header keyword values if they are
-present in the header.  The scaled data that is returned to the reading
-program will have
--
-        output value = (FITS value) * BSCALE + BZERO
--
-(a corresponding formula using TSCALn and TZEROn is used when reading
-from table columns).  In the case of integer output values the floating
-point scaled value is truncated to an integer (not rounded to the
-nearest integer).  The ftpscl and fttscl subroutines may be used to
-override the scaling parameters defined in the header (e.g., to turn
-off the scaling so that the program can read the raw unscaled values
-from the FITS file).
-
-When writing numerical data to the primary array or to a table
-column the data values will generally be automatically inversely scaled
-by the value of the BSCALE and BZERO (or TSCALn and TZEROn) header
-keyword values if they they exist in the header.  These keywords must
-have been written to the header before any data is written for them to
-have any effect.  Otherwise, one may use the ftpscl and fttscl
-subroutines to define or override the scaling keywords in the header
-(e.g., to turn off the scaling so that the program can write the raw
-unscaled values into the FITS file). If scaling is performed, the
-inverse scaled output value that is written into the FITS file will
-have
--
-         FITS value = ((input value) - BZERO) / BSCALE
--
-(a corresponding formula using TSCALn and TZEROn is used when
-writing to table columns).  Rounding to the nearest integer, rather
-than truncation, is performed when writing integer datatypes to the
-FITS file.
-
-**H.  Error Status Values and the Error Message Stack
-
-The last parameter in nearly every FITSIO subroutine is the error
-status value which is both an input and an output parameter.  A
-returned positive value for this parameter indicates an error was
-detected.  A listing of all the FITSIO status code values is given at
-the end of this document.
-
-The FITSIO library uses an `inherited status' convention for the status
-parameter which means that if a subroutine is called with a positive
-input value of the status parameter, then the subroutine will exit
-immediately without changing the value of the status parameter.  Thus,
-if one passes the status value returned from each FITSIO routine as
-input to the next FITSIO subroutine, then whenever an error is detected
-all further FITSIO processing will cease.  This convention can simplify
-the error checking in application programs because it is not necessary
-to check the value of the status parameter after every single FITSIO
-subroutine call.  If a program contains a sequence of several FITSIO
-calls, one can just check the status value after the last call.  Since
-the returned status values are generally distinctive, it should be
-possible to determine which subroutine originally returned the error
-status.  
-
-FITSIO also maintains an internal stack of error messages (80-character
-maximum length) which in many cases provide a more detailed explanation
-of the cause of the error than is provided by the error status number
-alone. It is recommended that the error message stack be printed out
-whenever a program detects a FITSIO error. To do this, call the FTGMSG
-routine repeatedly to get the successive messages on the stack. When the
-stack is empty FTGMSG will return a blank string. Note that this is a
-`First In -- First Out' stack, so the oldest error message is returned
-first by ftgmsg.
-
-**I.  Variable-Length Array Facility in Binary Tables
-
-FITSIO provides easy-to-use support for reading and writing data in
-variable length fields of a binary table. The variable length columns
-have TFORMn keyword values of the form `1Pt(len)' or `1Qt(len)' where `t' is the
-datatype code (e.g., I, J, E, D, etc.) and `len' is an integer
-specifying the maximum length of the vector in the table.  If the value
-of `len' is not specified when the table is created (e.g., if the TFORM
-keyword value is simply specified as '1PE' instead of '1PE(400) ), then
-FITSIO will automatically scan the table when it is closed to
-determine the maximum length of the vector and will append this value
-to the TFORMn value.
-
-The same routines which read and write data in an ordinary fixed length
-binary table extension are also used for variable length fields,
-however, the subroutine parameters take on a slightly different
-interpretation as described below.
-
-All the data in a variable length field is written into an area called
-the `heap' which follows the main fixed-length FITS binary table.  The
-size of the heap, in bytes, is specified with the PCOUNT keyword in the
-FITS header.  When creating a new binary table, the initial value of
-PCOUNT should usually be set to zero.  FITSIO will recompute the size
-of the heap as the data is written and will automatically update the
-PCOUNT keyword value when the table is closed.  When writing variable
-length data to a table, CFITSIO will automatically extend the size
-of the heap area if necessary, so that any following HDUs do not
-get overwritten.
-
-By default the heap data area starts immediately after the last row of
-the fixed-length table.  This default starting location may be
-overridden by the THEAP keyword, but this is not recommended.  
-If additional rows of data are added to the table, CFITSIO will
-automatically shift the the heap down to make room for the new
-rows, but it is obviously be more efficient to initially
-create the table with the necessary number of blank rows, so that
-the heap does not needed to be constantly moved.
-
-When writing to a variable length field, the entire array of values for
-a given row of the table must be written with a single call to FTPCLx.
-The total length of the array is calculated from (NELEM+FELEM-1). One
-cannot append more elements to an existing field at a later time; any
-attempt to do so will simply overwrite all the data which was previously
-written. Note also that the new data will be written to a new area of
-the heap and the heap space used by the previous write cannot be
-reclaimed. For this reason it is advised that each row of a variable
-length field only be written once. An exception to this general rule
-occurs when setting elements of an array as undefined. One must first
-write a dummy value into the array with FTPCLx, and then call FTPCLU to
-flag the desired elements as undefined. (Do not use the FTPCNx family
-of routines with variable length fields). Note that the rows of a table,
-whether fixed or variable length, do not have to be written
-consecutively and may be written in any order.
-
-When writing to a variable length ASCII character field (e.g., TFORM =
-'1PA') only a single character string written.  FTPCLS writes the whole
-length of the input string (minus any trailing blank characters), thus
-the NELEM and FELEM parameters are ignored.  If the input string is
-completely blank then FITSIO will write one blank character to the FITS
-file.  Similarly, FTGCVS and FTGCFS read the entire string (truncated
-to the width of the character string argument in the subroutine call)
-and also ignore the NELEM and FELEM parameters.
-
-The FTPDES subroutine is useful in situations where multiple rows of a
-variable length column have the identical array of values.  One can
-simply write the array once for the first row, and then use FTPDES to
-write the same descriptor values into the other rows (use the FTGDES
-routine to read the first descriptor value);  all the rows will then
-point to the same storage location thus saving disk space.
-
-When reading from a variable length array field one can only read as
-many elements as actually exist in that row of the table; reading does
-not automatically continue with the next row of the table as occurs
-when reading an ordinary fixed length table field.  Attempts to read
-more than this will cause an error status to be returned.  One can
-determine the number of elements in each row of a variable column with
-the FTGDES subroutine.
-
-**I.  Support for IEEE Special Values
-
-The ANSI/IEEE-754 floating-point number standard defines certain
-special values that are used to represent such quantities as
-Not-a-Number (NaN), denormalized, underflow, overflow, and infinity.
-(See the Appendix in the NOST FITS standard or the NOST FITS User's
-Guide for a list of these values).  The FITSIO subroutines that read
-floating point data in FITS files recognize these IEEE special values
-and by default interpret the overflow and infinity values as being
-equivalent to a NaN, and convert the underflow and denormalized values
-into zeros.  In some cases programmers may want access to the raw IEEE
-values, without any modification by FITSIO.  This can be done by
-calling the FTGPVx or FTGCVx routines while specifying 0.0 as the value
-of the NULLVAL parameter.  This will force FITSIO to simply pass the
-IEEE values through to the application program, without any
-modification.  This does not work for double precision values on
-VAX/VMS machines, however, where there is no easy way to bypass the
-default interpretation of the IEEE special values. This is also not 
-supported when reading floating-point images that have been compressed
-with the FITS tiled image compression convention that is discussed in
-section 5.6;  the pixels values in tile compressed images are
-represented by scaled integers, and a reserved integer value 
-(not a NaN) is used to represent undefined pixels.
-
-
-**J.  When the Final Size of the FITS HDU is Unknown
-
-It is not required to know the total size of a FITS data array or table
-before beginning to write the data to the FITS file.  In the case of
-the primary array or an image extension, one should initially create
-the array with the size of the highest dimension (largest NAXISn
-keyword) set to a dummy value, such as 1.  Then after all the data have
-been written and the true dimensions are known, then the NAXISn value
-should be updated using the fits\_ update\_key routine before moving to
-another extension or closing the FITS file.
-
-When writing to FITS tables, CFITSIO automatically keeps track of the
-highest row number that is written to, and will increase the size of
-the table if necessary.  CFITSIO will also automatically insert space
-in the FITS file if necessary, to ensure that the data 'heap', if it
-exists, and/or any additional HDUs that follow the table do not get
-overwritten as new rows are written to the table.
-
-As a general rule it is best to specify the initial number of rows = 0
-when the table is created, then let CFITSIO keep track of the number of
-rows that are actually written.  The application program should not
-manually update the number of rows in the table (as given by the NAXIS2
-keyword) since CFITSIO does this automatically.  If a table is
-initially created with more than zero rows, then this will usually be
-considered as the minimum size of the table, even if fewer rows are
-actually written to the table.  Thus, if a table is initially created
-with NAXIS2 = 20, and CFITSIO only writes 10 rows of data before
-closing the table, then NAXIS2 will remain equal to 20.  If however, 30
-rows of data are written to this table, then NAXIS2 will be increased
-from 20 to 30.  The one exception to this automatic updating of the
-NAXIS2 keyword is if the application program directly modifies the
-value of NAXIS2 (up or down) itself just before closing the table.  In this
-case, CFITSIO does not update NAXIS2 again, since it assumes that the
-application program must have had a good reason for changing the value
-directly.  This is not recommended, however, and is only provided for
-backward compatibility with software that initially creates a table
-with a large number of rows, than decreases the NAXIS2 value to the
-actual smaller value just before closing the table.
-
-**K.  Local FITS Conventions supported by FITSIO
-
-CFITSIO supports several local FITS conventions which are not
-defined in the official NOST FITS standard and which are not
-necessarily recognized or supported by other FITS software packages.
-Programmers should be cautious about using these features, especially
-if the FITS files that are produced are expected to be processed by
-other software systems which do not use the CFITSIO interface.
-
-***1.  Support for Long String Keyword Values.
-
-The length of a standard FITS string keyword is limited to 68
-characters because it must fit entirely within a single FITS header
-keyword record.  In some instances it is necessary to encode strings
-longer than this limit, so FITSIO supports a local convention in which
-the string value is continued over multiple keywords. This
-continuation convention uses an ampersand character at the end of each
-substring to indicate that it is continued on the next keyword, and the
-continuation keywords all have the name CONTINUE without an equal sign
-in column 9. The string value may be continued in this way over as many
-additional CONTINUE keywords as is required.  The following lines
-illustrate this continuation convention which is used in the value of
-the STRKEY keyword:
--
-LONGSTRN= 'OGIP 1.0'           / The OGIP Long String Convention may be used.
-STRKEY  = 'This is a very long string keyword&'  / Optional Comment
-CONTINUE  ' value that is continued over 3 keywords in the &  '
-CONTINUE  'FITS header.' / This is another optional comment.
--
-It is recommended that the LONGSTRN keyword, as shown
-here, always be included in any HDU that uses this longstring
-convention.  A subroutine called FTPLSW
-has been provided in CFITSIO to write this keyword if it does not
-already exist.
-
-This long string convention is supported by the following FITSIO
-subroutines that deal with string-valued keywords:
--
-      ftgkys - read a string keyword
-      ftpkls - write (append) a string keyword
-      ftikls - insert a string keyword
-      ftmkls - modify the value of an existing string keyword
-      ftukls - update an existing keyword, or write a new keyword
-      ftdkey - delete a keyword
--
-These routines will transparently read, write, or delete a long string
-value in the FITS file, so programmers in general do not have to be
-concerned about the details of the convention that is used to encode
-the long string in the FITS header.  When reading a long string, one
-must ensure that the character string parameter used in these
-subroutine calls has been declared long enough to hold the entire
-string, otherwise the returned string value will be truncated.
-
-Note that the more commonly used FITSIO subroutine to write string
-valued keywords (FTPKYS) does NOT support this long string convention
-and only supports strings up to 68 characters in length.  This has been
-done deliberately to prevent programs from inadvertently writing
-keywords using this non-standard convention without the explicit intent
-of the programmer or user.   The FTPKLS subroutine must be called
-instead to write long strings.  This routine can also be used to write
-ordinary string values less than 68 characters in length.
-
-***2.  Arrays of Fixed-Length Strings in Binary Tables
-
-CFITSIO supports 2 ways to specify that a character column in a binary
-table contains an array of fixed-length strings.  The first way, which
-is officially supported by the FITS Standard document, uses the TDIMn keyword.
-For example, if TFORMn = '60A' and TDIMn = '(12,5)' then that 
-column will be interpreted as containing an array of 5 strings, each 12
-characters long.
-
-FITSIO also supports a 
-local convention for the format of the TFORMn keyword value of the form
-'rAw' where 'r' is an integer specifying the total width in characters
-of the column, and 'w' is an integer specifying the (fixed) length of
-an individual unit string within the vector.  For example, TFORM1 =
-'120A10' would indicate that the binary table column is 120 characters
-wide and consists of 12 10-character length strings.  This convention
-is recognized by the FITSIO subroutines that read or write strings in
-binary tables.   The Binary Table definition document specifies that
-other optional characters may follow the datatype code in the TFORM
-keyword, so this local convention is in compliance with the
-FITS standard, although other FITS readers are not required to
-recognize this convention.
-
-The Binary Table definition document that was approved by the IAU in
-1994 contains an appendix describing an alternate convention for
-specifying arrays of fixed or variable length strings in a binary table
-character column (with the form 'rA:SSTRw/nnn)'.  This appendix was not
-officially voted on by the IAU and hence is still provisional.  FITSIO
-does not currently support this proposal.
-
-***3.  Keyword Units Strings
-
-One deficiency of the current FITS Standard is that it does not define
-a specific convention for recording the physical units of a keyword
-value.  The TUNITn keyword can be used to specify the physical units of
-the values in a table column, but there is no analogous convention for
-keyword values.  The comment field of the keyword is often used for
-this purpose, but the units are usually not specified in a well defined
-format that FITS readers can easily recognize and extract.
-
-To solve this deficiency, FITSIO uses a local convention in which the
-keyword units are enclosed in square brackets as the first token in the
-keyword comment field; more specifically, the opening square bracket
-immediately follows the slash '/' comment field delimiter and a single
-space character.  The following examples illustrate keywords that use
-this convention:
-
--
-EXPOSURE=               1800.0 / [s] elapsed exposure time
-V_HELIO =                16.23 / [km s**(-1)] heliocentric velocity
-LAMBDA  =                5400. / [angstrom] central wavelength
-FLUX    = 4.9033487787637465E-30 / [J/cm**2/s] average flux
--
-
-In general, the units named in the IAU(1988) Style Guide are
-recommended, with the main exception that the preferred unit for angle
-is 'deg' for degrees.
-
-The FTPUNT and FTGUNT subroutines in FITSIO write and read,
-respectively, the keyword unit strings in an existing keyword.
-
-***4.  HIERARCH Convention for Extended Keyword Names
-
-CFITSIO supports the HIERARCH keyword convention which allows keyword
-names that are longer then 8 characters and may contain the full range
-of printable ASCII text characters.  This convention 
-was developed at the European Southern Observatory (ESO)  to support 
-hierarchical FITS keyword such as:
--
-HIERARCH ESO INS FOCU POS = -0.00002500 / Focus position
--
-Basically, this convention uses the FITS keyword 'HIERARCH' to indicate
-that this convention is being used, then the actual keyword name
-({\tt'ESO INS FOCU POS'} in this example) begins in column 10 and can
-contain any printable ASCII text characters, including spaces.  The
-equals sign marks the end of the keyword name and is followed by the
-usual value and comment fields just as in standard FITS keywords.
-Further details of this convention are described at
-http://arcdev.hq.eso.org/dicb/dicd/dic-1-1.4.html (search for
-HIERARCH).
-
-This convention allows a much broader range of keyword names 
-than is allowed by the FITS Standard.  Here are more examples
-of such keywords:
--
-HIERARCH LongKeyword = 47.5 / Keyword has > 8 characters, and mixed case
-HIERARCH XTE$TEMP = 98.6 / Keyword contains the '$' character
-HIERARCH Earth is a star = F / Keyword contains embedded spaces
--
-CFITSIO will transparently read and write these keywords, so application
-programs do not in general need to know anything about the specific
-implementation details of the HIERARCH convention.  In particular,
-application programs do not need to specify the `HIERARCH' part of the
-keyword name when reading or writing keywords (although it
-may be included if desired).  When writing a keyword, CFITSIO first
-checks to see if the keyword name is legal as a standard FITS keyword
-(no more than 8 characters long and containing only letters, digits, or
-a minus sign or underscore). If so it writes it as a standard FITS
-keyword, otherwise it uses the hierarch convention to write the
-keyword.   The maximum keyword name length is 67 characters, which
-leaves only 1 space for the value field.  A more practical limit is
-about 40 characters, which leaves enough room for most keyword values.
-CFITSIO returns an error if there is not enough room for both the
-keyword name and the keyword value on the 80-character card, except for
-string-valued keywords which are simply truncated so that the closing
-quote character falls in column 80.  In the current implementation,
-CFITSIO preserves the case of the letters when writing the keyword
-name, but it is case-insensitive when reading or searching for a
-keyword.  The current implementation allows any ASCII text character
-(ASCII 32 to ASCII 126) in the keyword name except for the '='
-character.  A space is also required on either side of the equal sign.
-
-**L.  Optimizing Code for Maximum Processing Speed
-
-CFITSIO has been carefully designed to obtain the highest possible
-speed when reading and writing FITS files.  In order to achieve the
-best performance, however, application programmers must be careful to
-call the CFITSIO routines appropriately and in an efficient sequence;
-inappropriate usage of CFITSIO routines can greatly slow down the
-execution speed of a program.
-
-The maximum possible I/O speed of CFITSIO depends of course on the type
-of computer system that it is running on.  As a rough guide, the
-current generation of workstations can achieve speeds of 2 -- 10 MB/s
-when reading or writing FITS images and similar, or slightly slower
-speeds with FITS binary tables.  Reading of FITS files can occur at
-even higher rates (30MB/s or more) if the FITS file is still cached in
-system memory following a previous read or write operation on the same
-file.  To more accurately predict the best performance that is possible
-on any particular system, a diagnostic program called ``speed.c'' is
-included with the CFITSIO distribution which can be run to
-approximately measure the maximum possible speed of writing and reading
-a test FITS file.
-
-The following 2 sections provide some background on how CFITSIO
-internally manages the data I/O and describes some strategies that may
-be used to optimize the processing speed of software that uses
-CFITSIO.
-
-***1.  Background Information: How CFITSIO Manages Data I/O
-
-Many CFITSIO operations involve transferring only a small number of
-bytes to or from the FITS file (e.g, reading a keyword, or writing a
-row in a table); it would be very inefficient to physically read or
-write such small blocks of data directly in the FITS file on disk,
-therefore CFITSIO maintains a set of internal Input--Output (IO)
-buffers in RAM memory that each contain one FITS block (2880 bytes) of
-data.  Whenever CFITSIO needs to access data in the FITS file, it first
-transfers the FITS block containing those bytes into one of the IO
-buffers in memory.  The next time CFITSIO needs to access bytes in the
-same block it can then go to the fast IO buffer rather than using a
-much slower system disk access routine.  The number of available IO
-buffers is determined by the NIOBUF parameter (in fitsio2.h) and is
-currently set to 40.
-
-Whenever CFITSIO reads or writes data it first checks to see if that
-block of the FITS file is already loaded into one of the IO buffers.
-If not, and if there is an empty IO buffer available, then it will load
-that block into the IO buffer (when reading a FITS file) or will
-initialize a new block (when writing to a FITS file).  If all the IO
-buffers are already full, it must decide which one to reuse (generally
-the one that has been accessed least recently), and flush the contents
-back to disk if it has been modified before loading the new block.
-
-The one major exception to the above process occurs whenever a large
-contiguous set of bytes are accessed, as might occur when reading or
-writing a FITS image.  In this case CFITSIO bypasses the internal IO
-buffers and simply reads or writes the desired bytes directly in the
-disk file with a single call to a low-level file read or write
-routine.  The minimum threshold for the number of bytes to read or
-write this way is set by the MINDIRECT parameter and is currently set
-to 3 FITS blocks = 8640 bytes.  This is the most efficient way to read
-or write large chunks of data and can achieve IO transfer rates of
-5 -- 10MB/s or greater.  Note that this fast direct IO process is not
-applicable when accessing columns of data in a FITS table because the
-bytes are generally not contiguous since they are interleaved by the
-other columns of data in the table.  This explains why the speed for
-accessing FITS tables is generally slower than accessing
-FITS images.
-
-Given this background information, the general strategy for efficiently
-accessing FITS files should now be apparent:  when dealing with FITS
-images, read or write large chunks of data at a time so that the direct
-IO mechanism will be invoked;  when accessing FITS headers or FITS
-tables, on the other hand, once a particular FITS block has been
-loading into one of the IO buffers, try to access all the needed
-information in that block before it gets flushed out of the IO buffer.
-It is important to avoid the situation where the same FITS block is
-being read then flushed from a IO buffer multiple times.
-
-The following section gives more specific suggestions for optimizing
-the use of CFITSIO.
-
-***2.  Optimization Strategies
-
-1.  Because the data in FITS files is always stored in "big-endian" byte order,
-where the first byte of numeric values contains the most significant bits and the
-last byte contains the least significant bits, CFITSIO must swap the order of the bytes
-when reading or writing FITS files when running on little-endian machines (e.g., 
-Linux and Microsoft Windows operating systems running on PCs with x86 CPUs). 
-
-On fairly new CPUs that support "SSSE3" machine instructions 
-(e.g., starting with Intel Core 2 CPUs in 2007, and in AMD CPUs 
-beginning in 2011) significantly faster 4-byte and 8-byte swapping
-algorithms are available. These faster byte swapping functions are 
-not used by default in CFITSIO (because of the potential code 
-portablility issues), but users can enable them on supported 
-platforms by adding the appropriate compiler flags (-mssse3 with gcc
-or icc on linux) when compiling the swapproc.c source file, which will
-allow the compiler to generate code using the SSSE3 instruction set.
-A convenient way to do this is to configure the CFITSIO library
-with the following command:
--
-  >  ./configure --enable-ssse3
--
-Note, however, that a binary executable file that is 
-created using these faster functions will only run on 
-machines that support the SSSE3 machine instructions. It will
-crash on machines that do not support them.
-
-For faster 2-byte swaps on virtually all x86-64 CPUs (even those that
-do not support SSSE3), a variant using only SSE2 instructions exists.
-SSE2 is enabled by default on x86\_64 CPUs with 64-bit operating systems
-(and is also automatically enabled by the --enable-ssse3 flag).
-When running on x86\_64 CPUs with 32-bit operating systems, these faster 
-2-byte swapping algorithms are not used by default in CFITSIO, but can be 
-enabled explicitly with:
--
-./configure --enable-sse2
--
-Preliminary testing indicates that these SSSE3 and SSE2 based
-byte-swapping algorithms can boost the CFITSIO performance when 
-reading or writing FITS images by 20\% - 30\% or more.
-It is important to note, however, that compiler optimization must be
-turned on (e.g., by using the -O1 or -O2 flags in gcc) when building
-programs that use these fast byte-swapping algorithms in order
-to reap the full benefit of the SSSE3 and SSE2 instructions; without
-optimization, the code may actually run slower than when using
-more traditional byte-swapping techniques.
-
-2.  When dealing with a FITS primary array or IMAGE extension, it is
-more efficient to read or write large chunks of the  image at a time
-(at least 3 FITS blocks = 8640 bytes) so that the direct IO mechanism
-will be used as described in the previous section.  Smaller chunks of
-data are read or written via the IO buffers, which is somewhat less
-efficient because of the extra copy operation and additional
-bookkeeping steps that are required.  In principle it is more efficient
-to read or write as big an array of image pixels at one time as
-possible, however, if the array becomes so large that the operating
-system cannot store it all in RAM, then the performance may be degraded
-because of the increased swapping of virtual memory to disk.
-
-3.  When dealing with FITS tables, the most important efficiency factor
-in the software design is to read or write the data in the FITS file in
-a single pass through the file.  An example of poor program design
-would be to read a large, 3-column table by sequentially reading the
-entire first column, then going back to read the 2nd column, and
-finally the 3rd column; this obviously requires 3 passes through the
-file which could triple the execution time of an I/O limited program.
-For small tables this is not important, but when reading multi-megabyte
-sized tables these inefficiencies can become significant.  The more
-efficient procedure in this case is to read or write only as many rows
-of the table as will fit into the available internal I/O buffers, then
-access all the necessary columns of data within that range of rows.
-Then after the program is completely finished with the data in those
-rows it can move on to the next range of rows that will fit in the
-buffers, continuing in this way until the entire file has been
-processed.  By using this procedure of accessing all the columns of a
-table in parallel rather than sequentially, each block of the FITS file
-will only be read or written once.
-
-The optimal number of rows to read or write at one time in a given
-table depends on the width of the table row, on the number of I/O
-buffers that have been allocated in FITSIO, and also on the number of
-other FITS files that are open at the same time (since one I/O buffer
-is always reserved for each open FITS file).  Fortunately, a FITSIO
-routine is available that will return the optimal number of rows for a
-given table:  call ftgrsz(unit, nrows, status).  It is not critical to
-use exactly the value of nrows returned by this routine, as long as one
-does not exceed it.  Using a very small value however can also lead to
-poor performance because of the overhead from the larger number of
-subroutine calls.
-
-The optimal number of rows returned by ftgrsz is valid only as long as
-the application program is only reading or writing data in the
-specified table.  Any other calls to access data in the table header 
-would  cause additional blocks of data to be
-loaded into the I/O buffers displacing data from the original table,
-and should be avoided during the critical period while the table is
-being read or written.
-
-4.  Use binary table extensions rather than ASCII table
-extensions for better efficiency  when dealing with tabular data.  The
-I/O to ASCII tables is slower because of the overhead in formatting or
-parsing the ASCII data fields, and because ASCII tables are about twice
-as large as binary tables with the same information content.
-
-5. Design software so that it reads the FITS header keywords in the
-same order in which they occur in the file.  When reading keywords,
-FITSIO searches forward starting from the position of the last keyword
-that was read.  If it reaches the end of the header without finding the
-keyword, it then goes back to the start of the header and continues the
-search down to the position where it started.  In practice, as long as
-the entire FITS header can fit at one time in the available internal I/O
-buffers, then the header keyword access will be very fast and it makes
-little difference which order they are accessed.
-
-6. Avoid the use of scaling (by using the BSCALE and BZERO or TSCAL and
-TZERO keywords) in FITS files since the scaling operations add to the
-processing time needed to read or write the data.  In some cases it may
-be more efficient to temporarily turn off the scaling (using ftpscl or
-fttscl) and then read or write the raw unscaled values in the FITS
-file.
-
-7. Avoid using the 'implicit datatype conversion' capability in
-FITSIO.  For instance, when reading a FITS image with BITPIX = -32
-(32-bit floating point pixels), read the data into a single precision
-floating point data array in the program.  Forcing FITSIO to convert
-the data to a different datatype can significantly slow the program.
-
-8. Where feasible, design FITS binary tables using vector column
-elements so that the data are written as a contiguous set of bytes,
-rather than as single elements in multiple rows.  For example, it is
-faster to access the data in a table that contains a single row
-and 2 columns with TFORM keywords equal to  '10000E' and '10000J', than
-it is to access the same amount of data in a table with 10000 rows
-which has columns with the TFORM keywords equal to '1E' and '1J'.  In
-the former case the 10000 floating point values in the first column are
-all written in a contiguous block of the file which can be read or
-written quickly, whereas in the second case each floating point value
-in the first column is interleaved with the integer value in the second
-column of the same row so CFITSIO has to explicitly move to the
-position of each element to be read or written.
-
-9. Avoid the use of variable length vector columns in binary tables,
-since any reading or writing of these data requires that CFITSIO first
-look up or compute the starting address of each row of data in the
-heap.  In practice, this is probably not a significant efficiency issue.
-
-10. When copying data from one FITS table to another, it is faster to
-transfer the raw bytes instead of reading then writing each column of
-the table.  The FITSIO subroutines FTGTBS and FTPTBS (for ASCII
-tables), and  FTGTBB and FTPTBB (for binary tables) will perform
-low-level reads or writes of any contiguous range of bytes in a table
-extension.  These routines can be used to read or write a whole row (or
-multiple rows) of a table with a single subroutine call.   These
-routines are fast because they bypass all the usual data scaling, error
-checking and machine dependent data conversion that is normally done by
-FITSIO, and they allow the program to write the data to the output file
-in exactly the same byte order.  For these same reasons, use of these
-routines can be somewhat risky because no validation or machine
-dependent conversion is performed by these routines.  In general these
-routines are only recommended for optimizing critical pieces of code
-and should only be used by programmers who thoroughly understand the
-internal byte structure of the FITS tables they are reading or
-writing.
-
-11. Another strategy for improving the speed of writing a FITS table,
-similar to the previous one, is to directly construct the entire byte
-stream for a whole table row (or multiple rows) within the application
-program and then write it to the FITS file with
-ftptbb.  This avoids all the overhead normally present
-in the column-oriented CFITSIO write routines.  This technique should
-only be used for critical applications, because it makes the code more
-difficult to understand and maintain, and it makes the code more system
-dependent (e.g., do the bytes need to be swapped before writing to the
-FITS file?).
-
-12.  Finally, external factors such as the type of magnetic disk
-controller (SCSI or IDE), the size of the disk cache, the average seek
-speed of the disk, the amount of disk fragmentation, and the amount of
-RAM available on the system can all have a significant impact on
-overall I/O efficiency.  For critical applications, a system
-administrator should review the proposed system hardware to identify any
-potential I/O bottlenecks.

-*VII.  Basic Interface Routines
-
-This section defines a basic set of subroutines that can be
-used to perform the most common types of read and write operations
-on FITS files.  New users should start with these subroutines and
-then, as needed, explore the more advance routines described in
-the following chapter to perform more complex or specialized operations.
-
-A right arrow symbol ($>$) is used to separate the input parameters from
-the output parameters in the  definition of each routine.  This symbol
-is not actually part of the calling sequence.  Note that
-the status parameter is both an input and an output parameter
-and must be initialized = 0 prior to calling the FITSIO subroutines.
-
-Refer to Chapter 9 for the definition of all the parameters 
-used by these interface routines.
-
-**A.  FITSIO Error Status Routines \label{FTVERS}
-
->1  Return the current version number of the fitsio library.
-    The version number will be incremented with each new
->   release of CFITSIO.
--
-        FTVERS( > version)
--
->2  Return the descriptive text string corresponding to a FITSIO error
-    status code.   The 30-character length string contains a brief
->   description of the cause of the error.
--
-        FTGERR(status, > errtext)
--
->3  Return the top (oldest) 80-character error message from the
-    internal FITSIO stack of error messages and shift any remaining
-    messages on the stack up one level.  Any FITSIO error will
-    generate one or more messages on the stack.  Call this routine
-    repeatedly to get each message in sequence.  The error stack is empty
->   when a blank string is returned.
--
-        FTGMSG( > errmsg)
--
->4 The FTPMRK routine puts an invisible marker on the 
-   CFITSIO error stack.  The FTCMRK routine can then be
-   used to delete any more recent error messages on the stack, back to
-   the position of the marker.  This preserves any older error messages
-   on the stack.  FTCMSG simply clears the entire error message stack.
->  These routines are called without any arguments.
--
-        FTPMRK
-        FTCMRK
-        FTCMSG
--
-
->5  Print out the error message corresponding to the input status
-    value and all the error messages on the FITSIO stack  to the specified
-    file stream  (stream can be either the string 'STDOUT' or 'STDERR').
->   If the input status value = 0 then this routine does nothing.
--
-       FTRPRT (stream, > status)
--
->6  Write an 80-character message to the FITSIO error stack.  Application
-    programs should not normally write to the stack, but there may be
->   some situations where this is desirable.
--
-        FTPMSG(errmsg)
--
-
-**B.  File I/O Routines
-
->1 Open an existing FITS file with readonly or readwrite access.
-   This routine always opens the primary array (the first HDU) of 
-   the file, and does not move to a following extension, if one was
-   specified as part of the filename.   Use the FTNOPN routine to
-   automatically move to the extension.  This routine will also
-   open IRAF images (.imh format files) and raw binary data arrays
-   with READONLY access by first converting them on the fly into
-   virtual FITS images.  See the `Extended File Name Syntax' chapter
-   for more details.  The FTDKOPEN routine simply opens the specified
-   file without trying to interpret the filename using the extended
->  filename syntax.
--
-        FTOPEN(unit,filename,rwmode, > blocksize,status)
-        FTDKOPEN(unit,filename,rwmode, > blocksize,status)
--
->2 Open an existing FITS file with readonly or readwrite access
-   and move to a following extension, if one was specified as
-   part of the filename.  (e.g.,  'filename.fits+2' or
-   'filename.fits[2]' will move to the 3rd HDU in the file).
-   Note that this routine differs from FTOPEN in that it does not
->  have the redundant blocksize argument.
--
-        FTNOPN(unit,filename,rwmode, > status)
--
->3 Open an existing FITS file with readonly or readwrite access
-   and then move to the first HDU containing significant data, if a) an HDU
-   name or number to open was not explicitly specified as part of the
-   filename, and b) if the FITS file contains a null primary array (i.e.,
-   NAXIS = 0).  In this case, it will look for the first IMAGE HDU with
-   NAXIS > 0, or the first table that does not contain the strings `GTI'
-   (Good Time Interval) or `OBSTABLE' in the EXTNAME keyword value.  FTTOPN
-   is similar, except it will move to the first significant table HDU
-   (skipping over any image HDUs) in the file if a specific HDU name
-   or number is not specified.  FTIOPN will move to the first non-null
->  image HDU, skipping over any tables.
--
-        FTDOPN(unit,filename,rwmode, > status)
-        FTTOPN(unit,filename,rwmode, > status)
-        FTIOPN(unit,filename,rwmode, > status)
--
->4 Open and initialize a new empty FITS file.   A template file may also be
-   specified to define the structure of the new file (see section 4.2.4).
-   The FTDKINIT routine simply creates the specified
-   file without trying to interpret the filename using the extended
->  filename syntax.
--
-        FTINIT(unit,filename,blocksize, > status)
-        FTDKINIT(unit,filename,blocksize, > status)
--
->>5 Close a FITS file previously opened with ftopen or ftinit
--
-        FTCLOS(unit, > status)
--
->6  Move to a specified (absolute) HDU in the FITS file (nhdu = 1 for the
->   FITS primary array)
--
-        FTMAHD(unit,nhdu, > hdutype,status)
--
->7  Create a primary array (if none already exists), or insert a 
-    new IMAGE extension immediately following the CHDU, or
-    insert a new Primary Array at the beginning of the file.  Any
-    following extensions in the file will be shifted down to make room
-    for the new extension.  If the CHDU is the last HDU in the file
-    then the new image extension will simply be appended to the end of
-    the file.   One can force a new primary array to be inserted at the
-    beginning of the FITS file by setting status = -9 prior
-    to calling the routine.  In this case the existing primary array will be
-    converted to an IMAGE extension. The new extension (or primary
-    array) will become the CHDU.  The FTIIMGLL routine is identical
-    to the FTIIMG routine except that the 4th parameter (the length
-    of each axis) is an array of 64-bit integers rather than an array
->   of 32-bit integers.
--
-        FTIIMG(unit,bitpix,naxis,naxes, > status) 
-        FTIIMGLL(unit,bitpix,naxis,naxesll, > status) 
--
->8  Insert a new ASCII TABLE extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new table extension will simply be appended to the
-    end of the file.  The new extension will become the CHDU. The FTITABLL
-    routine is identical
-    to the FTITAB routine except that the 2nd and 3rd parameters (that give
-    the size of the table) are 64-bit integers rather than 
-    32-bit integers.  Under normal circumstances, the nrows and nrowsll 
-    paramenters should have a value of 0; CFITSIO will automatically update
->   the number of rows as data is written to the table.
--
-        FTITAB(unit,rowlen,nrows,tfields,ttype,tbcol,tform,tunit,extname, >
-               status)
-        FTITABLL(unit,rowlenll,nrowsll,tfields,ttype,tbcol,tform,tunit,extname, >
-               status)
--
->9  Insert a new binary table extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new bintable extension will simply be appended to the
-     end of the file.  The new extension will become the CHDU. The FTIBINLL
-    routine is identical
-    to the FTIBIN routine except that the 2nd parameter (that gives
-    the length of the table) is a 64-bit integer rather than 
-    a 32-bit integer. Under normal circumstances, the nrows and nrowsll

--
-        FTPREC(unit,card, > status)
--
->2  Put (append) a new keyword of the appropriate datatype into the CHU. 
-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the
-     precision.  This will suppress trailing zeros, and will use a
-     fixed format rather than an exponential format,
->    depending on the magnitude of the value.
--
-        FTPKY[JKLS](unit,keyword,keyval,comment, > status)
-        FTPKY[EDFG](unit,keyword,keyval,decimals,comment, > status)  
--
->3 Get the nth 80-character header record from the CHU.  The first keyword
-   in the header is at key\_no = 1;  if key\_no = 0 then this subroutine
-   simple moves the internal pointer to the beginning of the header
-   so that subsequent keyword operations will start at the top of 
->  the header; it also returns a blank card value in this case.

-**D.  Data I/O Routines
-
-The following routines read or write data values in the current HDU of
-the FITS file.  Automatic datatype conversion 
-will be attempted for numerical datatypes if the specified datatype is 
-different from the actual datatype of the FITS array or table column.
-
->>1 Write elements into the primary data array or image extension.
--
-        FTPPR[BIJKED](unit,group,fpixel,nelements,values, > status)
--
->2  Read elements from the primary data array or image extension.  
-    Undefined array elements will be 
-    returned with a value = nullval, unless nullval = 0 in which case no 
-    checks for undefined pixels will be performed. The anyf parameter is 
-    set to true (= .true.) if any of the returned
->   elements were undefined.
--
-        FTGPV[BIJKED](unit,group,fpixel,nelements,nullval, > values,anyf,status)
--
->3  Write elements into an ASCII or binary table column. The `felem'
-    parameter applies only to vector columns in binary tables and is 
->   ignored when writing to ASCII tables.
--
-        FTPCL[SLBIJKEDCM](unit,colnum,frow,felem,nelements,values, > status)
--
->4  Read elements from an ASCII or binary table column.  Undefined
-    array elements will be returned with a value = nullval, unless nullval = 0 
-    (or = ' ' for ftgcvs) in which case no checking for undefined values will
-    be performed. The ANYF parameter is set to true if any of the returned
-    elements are undefined. 
-
-    Any column, regardless of it's intrinsic datatype, may be read as a
-    string.  It should be noted however that reading a numeric column
-    as a string is 10 - 100 times slower than reading the same column
-    as a number due to the large overhead in constructing the formatted
-    strings.  The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    datatype of the column.  The length of the returned strings  can be
-    determined with the ftgcdw routine.  The following TDISPn display
-    formats are currently supported:
--
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
--
-  where w is the width in characters of the displayed values, m is the minimum
-  number of digits displayed, and d is the number of digits to the right of the 
->  decimal.  The .m field is optional.

-*VIII   Advanced Interface Subroutines
-
-This chapter defines all the available subroutines in the FITSIO user
-interface. For completeness, the basic subroutines described in the
-previous chapter are also repeated here. A right arrow symbol is used
-here to separate the input parameters from the output parameters in the
-definition of each subroutine. This symbol is not actually part of the
-calling sequence. An alphabetical list and definition of all the
-parameters is given at the end of this section. 
-
-**A.  FITS File Open and Close Subroutines: \label{FTOPEN}
-
->1 Open an existing FITS file with readonly or readwrite access. The 
-FTDKOPEN routine simply opens the specified file without trying to 
-interpret the filename using the extended filename syntax. FTDOPN opens
-the file and 
-also moves to the first HDU containing significant data, if no specific
-HDU is specified as part of the filename.  FTTOPN and FTIOPN are similar
-except that they will move to the first table HDU or image HDU, respectively,
->if a HDU name or number is not specified as part of the filename.
--
-        FTOPEN(unit,filename,rwmode, > blocksize,status)
-        FTDKOPEN(unit,filename,rwmode, > blocksize,status)
-
-        FTDOPN(unit,filename,rwmode, > status)
-        FTTOPN(unit,filename,rwmode, > status)
-        FTIOPN(unit,filename,rwmode, > status)
--
-
->2 Open an existing FITS file with readonly or readwrite access
-   and move to a following extension, if one was specified as
-   part of the filename.  (e.g.,  'filename.fits+2' or
-   'filename.fits[2]' will move to the 3rd HDU in the file).
-   Note that this routine differs from FTOPEN in that it does not
->  have the redundant blocksize argument.
--
-        FTNOPN(unit,filename,rwmode, > status)
--
->3  Reopen a FITS file that was previously opened with 
-    FTOPEN, FTNOPN, or FTINIT.  The newunit number
-    may then be treated as a separate file, and one may
-    simultaneously read or write to 2 (or more)  different extensions in
-    the same file.   The FTOPEN and FTNOPN routines (above) automatically
-    detects cases where a previously opened file is being opened again,
-    and then internally call FTREOPEN, so programs should rarely
->   need to explicitly call this routine.
--
-       FTREOPEN(unit, > newunit, status)
--
->4 Open and initialize a new empty FITS file.
-   The FTDKINIT routine simply creates the specified
-   file without trying to interpret the filename using the extended
->  filename syntax.
--
-       FTINIT(unit,filename,blocksize, > status)
-       FTDKINIT(unit,filename,blocksize, > status)
--
-
->5   Create a new FITS file, using a template file to define its
-  initial size and structure.  The template may be another FITS HDU
-  or an ASCII template file.  If the input template file name
-  is blank, then this routine behaves the same as FTINIT.
-  The currently supported format of the ASCII template file is described
-  under the fits\_parse\_template routine (in the general Utilities 
-  section), but this may change slightly later releases of
-> CFITSIO.
--
-       FTTPLT(unit, filename, tplfilename, > status)
--
->6 Flush internal buffers of data to the output FITS file 
-   previously opened with ftopen or ftinit.  The routine usually
-   never needs to be called, but doing so will ensure that
-   if the program subsequently aborts, then the FITS file will
->  have at least been closed properly.
--
-        FTFLUS(unit, > status)
--
->>7 Close a FITS file previously opened with ftopen or ftinit
--
-        FTCLOS(unit, > status)
--
->8  Close and DELETE a FITS file previously opened with ftopen or ftinit.
-    This routine may be  useful in cases where a FITS file is created, but
->   an error occurs which prevents the complete file from being written.
--
-        FTDELT(unit, > status)
--
->9  Get the value of an unused I/O unit number which may then be used
-    as input to FTOPEN or FTINIT.  This routine searches for the first
-    unused unit number in the range from with 99 down to 50.   This
-    routine just keeps an internal list of the allocated unit numbers
-    and does not physically check that the Fortran unit is available (to be
-    compatible with the SPP version of FITSIO).  Thus users must not
-    independently allocate any unit numbers in the range 50 - 99 
-    if this routine is also to be used in the same program.  This 
-    routine is provided for convenience only, and it is not required 
->   that the unit numbers used by FITSIO be allocated by this routine.
--
-        FTGIOU( > iounit, status)
--
->10  Free (deallocate) an I/O unit number which was previously allocated
-    with FTGIOU.   All previously allocated unit numbers may be
->   deallocated at once by calling FTFIOU with iounit = -1.
--
-        FTFIOU(iounit, > status)
--
->11  Return the Fortran unit number that corresponds to the C fitsfile
-pointer value, or vice versa.  These 2 C routines may be useful in 
-mixed language programs where both C and Fortran subroutines need
-to access the same file.  For example, if a FITS file is opened
-with unit 12 by a Fortran subroutine, then a C routine within the
-same program could get the fitfile pointer value to access the same file
-by calling  'fptr = CUnit2FITS(12)'.  These routines return a value
->of zero if an error occurs.
--
-      int       CFITS2Unit(fitsfile *ptr);
-      fitsfile* CUnit2FITS(int unit);
--
-
->11  Parse the input filename and return the HDU number that would be
-moved to if the file were opened with FTNOPN.    The returned HDU
-number begins with 1 for the primary array, so for example, if the
-input filename = `myfile.fits[2]' then hdunum = 3 will be returned.
-FITSIO does not open the file to check if the extension actually exists
-if an extension number is specified. If an extension *name* is included
-in the file name specification (e.g.  `myfile.fits[EVENTS]' then this
-routine will have to open the FITS file and look for the position of
-the named extension, then close file again.  This is not possible if
-the file is being read from the stdin stream, and an error will be
-returned in this case.  If the filename does not specify an explicit
-extension (e.g. 'myfile.fits') then hdunum = -99 will be returned,
-which is functionally equivalent to hdunum = 1. This routine is mainly
-used for backward compatibility in the ftools software package and is
-not recommended for general use.  It is generally better and more
-efficient to first open the FITS file with FTNOPN, then use FTGHDN to
-determine which HDU in the file has been opened, rather than calling
-> FTEXTN followed by a call to FTNOPN.
--
-        FTEXTN(filename, > nhdu, status)
--
->>12 Return the name of the opened FITS file. 
--
-        FTFLNM(unit, > filename, status)
--
->>13 Return the I/O mode of the open FITS file (READONLY = 0, READWRITE = 1).
--
-        FTFLMD(unit, > iomode, status)
--
->14 Return the file type of the opened FITS file (e.g. 'file://', 'ftp://',
->  etc.).
--
-        FTURLT(unit, > urltype, status)
--
->15  Parse the input filename or URL into its component parts: the file
-type (file://, ftp://, http://, etc), the base input file name, the
-name of the output file that the input file is to be copied to prior
-to opening, the HDU or extension specification, the filtering
-specifier, the binning specifier, and the column specifier.  Blank
-strings will be returned for any components that are not present
->in the input file name.
--
-       FTIURL(filename, > filetype, infile, outfile, extspec, filter, 
-               binspec, colspec, status)
--
->16 Parse the input file name and return the root file name.  The root
-name includes the file type if specified, (e.g.  'ftp://' or 'http://')
-and the full path name, to the extent that it is specified in the input
-filename.  It does not include the HDU name or number, or any filtering
->specifications.
--
-       FTRTNM(filename, > rootname, status)
--
-
->16 Test if the input file or a compressed version of the file (with
-a .gz, .Z, .z, or .zip extension) exists on disk.  The returned value of 
-the 'exists' parameter will have 1 of the 4 following values:
--
-   2:  the file does not exist, but a compressed version does exist
-   1:  the disk file does exist
-   0:  neither the file nor a compressed version of the file exist
-  -1:  the input file name is not a disk file (could be a ftp, http,
-       smem, or mem file, or a file piped in on the STDIN stream)
--
-> 
--
-      FTEXIST(filename, > exists, status);
--
-**B.  HDU-Level Operations \label{FTMAHD}
-
-When a FITS file is first opened or created, the internal buffers in
-FITSIO automatically point to the first HDU in the file.  The following
-routines may be used to move to another HDU in the file.  Note that
-the HDU numbering convention used in FITSIO  denotes the primary array
-as the first HDU, the first extension in a FITS file is the second HDU,
-and so on.
-
->1  Move to a specified (absolute) HDU in the FITS file (nhdu = 1 for the
->   FITS primary array)
--
-        FTMAHD(unit,nhdu, > hdutype,status)
--
->>2 Move to a new (existing) HDU forward or backwards relative to the CHDU
--
-        FTMRHD(unit,nmove, > hdutype,status)  
--
->3  Move to the (first) HDU which has the specified extension type and
-    EXTNAME (or HDUNAME) and EXTVER keyword values.  The hdutype parameter
-    may have
-    a value of IMAGE\_HDU (0), ASCII\_TBL (1), BINARY\_TBL (2), or ANY\_HDU (-1)
-    where ANY\_HDU means that only the extname and extver values will be
-    used to locate the correct extension.  If the input value of
-    extver is 0 then the EXTVER keyword is ignored and the first HDU
-    with a matching EXTNAME (or HDUNAME) keyword will be found.  If no
-    matching HDU is found in the file then the current HDU will remain
-    unchanged
->   and a status = BAD\_HDU\_NUM (301) will be returned. 
--
-        FTMNHD(unit, hdutype, extname, extver, > status)
--
->>4 Get the number of the current HDU in the FITS file (primary array = 1)
--
-        FTGHDN(unit, > nhdu)
--
->5  Return the type of the current HDU in the FITS file.  The possible
->   values for hdutype are IMAGE\_HDU (0), ASCII\_TBL (1), or BINARY\_TBL (2).  
--
-        FTGHDT(unit, > hdutype, status)
--
->6  Return the total number of HDUs in the FITS file.
->   The CHDU remains unchanged. 
--
-        FTTHDU(unit, > hdunum, status)
--
->7 Create (append) a new empty HDU following the last extension that
-    has been previously accessed by the program.   This will overwrite
-    any extensions in an existing FITS file if the program has not already
-    moved to that (or a later) extension using the FTMAHD or FTMRHD routines.
-    For example, if an existing FITS file contains a primary array and 5 
-    extensions and a program (1) opens the FITS file, (2) moves to
-    extension 4, (3) moves back to the primary array, and (4) then calls
-    FTCRHD, then the new extension will be written following the 4th
->   extension, overwriting the existing 5th extension. 
--
-        FTCRHD(unit, > status)
--
-
->8  Create a primary array (if none already exists), or insert a 
-    new IMAGE extension immediately following the CHDU, or
-    insert a new Primary Array at the beginning of the file.  Any
-    following extensions in the file will be shifted down to make room
-    for the new extension.  If the CHDU is the last HDU in the file
-    then the new image extension will simply be appended to the end of
-    the file.   One can force a new primary array to be inserted at the
-    beginning of the FITS file by setting status = -9 prior
-    to calling the routine.  In this case the existing primary array will be
-    converted to an IMAGE extension. The new extension (or primary
-    array) will become the CHDU.  The FTIIMGLL routine is identical
-    to the FTIIMG routine except that the 4th parameter (the length
-    of each axis) is an array of 64-bit integers rather than an array
->   of 32-bit integers.
--
-        FTIIMG(unit,bitpix,naxis,naxes, > status) 
-        FTIIMGLL(unit,bitpix,naxis,naxesll, > status) 
--
->9  Insert a new ASCII TABLE extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new table extension will simply be appended to the
-    end of the file.  The new extension will become the CHDU. The FTITABLL
-    routine is identical
-    to the FTITAB routine except that the 2nd and 3rd parameters (that give
-    the size of the table) are 64-bit integers rather than 
->   32-bit integers.
--
-        FTITAB(unit,rowlen,nrows,tfields,ttype,tbcol,tform,tunit,extname, >
-               status)
-        FTITABLL(unit,rowlenll,nrowsll,tfields,ttype,tbcol,tform,tunit,extname, >
-               status)
--
-
->10  Insert a new binary table extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new bintable extension will simply be appended to the
-    end of the file.  The new extension will become the CHDU. The FTIBINLL
-    routine is identical
-    to the FTIBIN routine except that the 2nd parameter (that gives
-    the length of the table) is a 64-bit integer rather than 
->   a 32-bit integer.
--
-        FTIBIN(unit,nrows,tfields,ttype,tform,tunit,extname,varidat > status)
-        FTIBINLL(unit,nrowsll,tfields,ttype,tform,tunit,extname,varidat > status)
-
--
-
->11  Resize an image by modifing the size, dimensions, and/or datatype of the 
-    current primary array or image extension. If the new image, as specified
-    by the input arguments, is larger than the current existing image
-    in the FITS file then zero fill data will be inserted at the end
-    of the current image and any following extensions will be moved 
-    further back in the file.  Similarly, if the new image is
-    smaller than the current image then any following extensions
-    will be shifted up towards the beginning of the FITS file
-    and the image data will be truncated to the new size.
-    This routine rewrites the BITPIX, NAXIS, and NAXISn keywords
-    with the appropriate values for new image. The FTRSIMLL routine is identical
-    to the FTRSIM routine except that the 4th parameter (the length
-    of each axis) is an array of 64-bit integers rather than an array
->   of 32-bit integers.
--
-        FTRSIM(unit,bitpix,naxis,naxes,status)
-        FTRSIMLL(unit,bitpix,naxis,naxesll,status)
--
->12 Delete the CHDU in the FITS file.  Any following HDUs will be shifted
-    forward in the file, to fill in the gap created by the deleted
-    HDU.  In the case of deleting the primary array (the first HDU in
-    the file) then the current primary array will be replace by a null
-    primary array containing the minimum set of required keywords and
-    no data.  If there are more extensions in the file following the
-    one that is deleted, then the the CHDU will be redefined to point
-    to the following extension.  If there are no following extensions
-    then the CHDU will be redefined to point to the previous HDU.  The
-    output HDUTYPE parameter indicates the type of the new CHDU after
->   the previous CHDU has been deleted.
--
-        FTDHDU(unit, > hdutype,status)
--
->13  Copy all or part of the input FITS file and append it
-    to the end of the output FITS file.  If 'previous' (an integer parameter) is
-    not equal to 0, then any HDUs preceding the current HDU in the input file
-    will be copied to the output file.  Similarly, 'current' and 'following'
-    determine whether the current HDU, and/or any following HDUs in the input
-    file will be copied to the output file. If all 3 parameters are not equal
-    to zero, then the entire input file will be copied.  On return, the current
-    HDU in the input file will be unchanged, and the last copied HDU will be the 
->   current HDU in the output file.     
--
-        FTCPFL(iunit, ounit, previous, current, following, > status)
--
->14 Copy the entire CHDU from the FITS file associated with IUNIT to the CHDU 
-    of the FITS file associated with OUNIT. The output HDU must be empty and
-    not already contain any keywords.  Space will be reserved for MOREKEYS
-    additional  keywords in the output header if there is not already enough 
->   space. 
--
-        FTCOPY(iunit,ounit,morekeys, > status)
--
->15 Copy the header (and not the data) from the CHDU associated with inunit
-    to the CHDU associated with outunit.  If the current output HDU
-    is not completely empty, then the CHDU will be closed and a new
-    HDU will be appended to the output file.  This routine will automatically
-    transform the necessary keywords when copying a primary array to
-    and image extension, or an image extension to a primary array. 
->   An empty output data unit will be created (all values = 0). 
--
-        FTCPHD(inunit, outunit, > status)
--
->16 Copy just the data from the CHDU associated with IUNIT 
-    to the CHDU associated with OUNIT. This will overwrite 
-    any data previously in the OUNIT CHDU.  This low level routine is used
-    by FTCOPY, but it may also be useful in certain application programs
-    which want to copy the data from one FITS file to another but also
-    want to modify the header keywords in the process. all the required 
-    header keywords must be written to the OUNIT CHDU before calling
->   this routine 
--
-        FTCPDT(iunit,ounit, > status)
--
-
-**C.  Define or Redefine the structure of the CHDU \label{FTRDEF}
-
-It should rarely be necessary to call the subroutines in this section.
-FITSIO internally calls these routines whenever necessary, so any calls
-to these routines by application programs will likely be redundant.
-
->1  This routine forces FITSIO to scan the current header keywords that
-    define the structure of the HDU (such as the NAXISn, PCOUNT and GCOUNT
-    keywords) so that it can initialize the internal buffers that describe
-    the HDU structure.  This routine may be used instead of the more
-    complicated calls to ftpdef, ftadef or ftbdef.  This routine is
-    also very useful for reinitializing the structure of an HDU, 
-    if the number of rows in a table, as specified by the NAXIS2 keyword,
->   has been modified from its initial value.
--
-        FTRDEF(unit, > status)   (DEPRECATED)
--
->2 Define the structure of the primary array or IMAGE extension.  When
-   writing GROUPed FITS files that by convention set the NAXIS1 keyword
-   equal to 0, ftpdef must be called with naxes(1) = 1, NOT 0, otherwise
-   FITSIO will report an error status=308 when trying to write data
-   to a group. Note: it is usually simpler to call FTRDEF rather
->  than this routine.
--
-        FTPDEF(unit,bitpix,naxis,naxes,pcount,gcount, > status)  (DEPRECATED)
--
->3  Define the structure of an ASCII table (TABLE) extension. Note: it 
->   is usually simpler to call FTRDEF rather than this routine.
--

-    This is useful if one does not know the total size of the data unit until
-    after the data have been written.  The size (in bytes) of an ASCII or 
-    Binary table is given by NAXIS1 * NAXIS2.  (Note that to determine the
-    value of NAXIS1 it is often more convenient to read the value of the
-    NAXIS1 keyword from the output file, rather than computing the row 
-    length directly from all the TFORM keyword values).  Note: it

-    to start immediately following the regular table data, i.e., at
-    location NAXIS1 x NAXIS2.  This routine is only relevant for 
-    binary tables which contain variable length array columns (with
-    TFORMn = 'Pt').  This subroutine also automatically writes
-    the value of theap to a keyword in the extension header.  This 
-    subroutine must be called after the required keywords have been
-    written (with ftphbn) and after the table structure has been defined

-**D.  FITS Header I/O Subroutines
-
-***1.  Header Space and Position Routines \label{FTHDEF}
-
->1  Reserve space in the CHU for MOREKEYS more header keywords.  
-    This subroutine may be called to reserve space for keywords which are
-    to be written at a later time, after the data unit or subsequent
-    extensions have been written to the FITS file.  If this subroutine is
-    not explicitly called, then the initial size of the FITS header will be
-    limited to the space available at the time that  the first data is written
-    to the associated data unit.   FITSIO has the ability to dynamically
-    add more space to the header if needed, however it is more efficient
->   to preallocate the required space if the size is known in advance.
--
-        FTHDEF(unit,morekeys, > status)
--
->2  Return the number of existing keywords in the CHU (NOT including the
-    END keyword which is not considered a real keyword) and the remaining
-    space available to write additional keywords in the CHU.  (returns
-    KEYSADD = -1 if the header has not yet been closed).
-    Note that FITSIO will attempt to dynamically add space for more 
->   keywords if required when appending new keywords to a header.
--
-        FTGHSP(iunit, > keysexist,keysadd,status)
--
->3  Return the number of keywords in the header and the current position 
-    in the header.  This returns the number of the keyword record that 
-    will be read next (or one greater than the position of the last keyword 
-    that was read or written). A value of 1 is returned if the pointer is
->   positioned at the beginning of the header.  
--
-        FTGHPS(iunit, > keysexist,key_no,status)
--
-***2.  Read or Write Standard Header Routines \label{FTPHPR}
-
-These subroutines provide a simple method of reading or writing most of
-the keyword values that are normally required in a FITS files.  These
-subroutines are provided for convenience only and are not required to
-be used.  If preferred, users may call the lower-level subroutines
-described in the previous section to individually read or write the
-required keywords.  Note that in most cases, the required keywords such
-as NAXIS, TFIELD, TTYPEn, etc, which define the structure of the HDU
-must be written to the header before any data can be written to the
-image or table.
-
->1  Put the primary header or IMAGE extension keywords into the CHU.
-There are 2 available routines: The simpler FTPHPS routine is
-equivalent to calling ftphpr with the default values of SIMPLE = true,
-pcount = 0, gcount = 1, and EXTEND = true.  PCOUNT, GCOUNT and EXTEND
-keywords are not required in the primary header and are only written if
-pcount is not equal to zero, gcount is not equal to zero or one, and if
-extend is TRUE, respectively.  When writing to an IMAGE extension, the
->SIMPLE and EXTEND parameters are ignored.

--
->5 Put the binary table header keywords into the CHU. The optional
-   TUNITn and EXTNAME keywords are written only if the input string
-   values are not blank.  The pcount parameter, which specifies the
-   size of the variable length array heap, should initially = 0;
-   FITSIO will automatically update the PCOUNT keyword value if any
-   variable length array data is written to the heap.  The TFORM keyword
-   value for variable length vector columns should have the form 'Pt(len)'
-   or '1Pt(len)' where `t' is the data type code letter (A,I,J,E,D, etc.)
-   and  `len' is an integer specifying the maximum length of the vectors
-   in that column (len must be greater than or equal to the longest
-   vector in the column).  If `len' is not specified when the table is
-   created (e.g., the input TFORMn value is just '1Pt') then FITSIO will
-   scan the column when the table is first closed and will append the
-   maximum length to the TFORM keyword value.  Note that if the table
-   is subsequently modified to increase the maximum length of the vectors
-   then the modifying program is responsible for also updating the TFORM 
->  keyword value.

-***3.  Write Keyword Subroutines \label{FTPREC}
-
->>1 Put (append) an 80-character record into the CHU. 
--
-        FTPREC(unit,card, > status)
--
->2  Put (append) a COMMENT keyword into the CHU.  Multiple COMMENT keywords
->   will be written if the input comment string is longer than 72 characters. 
--
-        FTPCOM(unit,comment, > status)
--
->3 Put (append) a HISTORY keyword into the CHU.  Multiple HISTORY keywords
->   will be written if the input history string is longer than 72 characters.
--
-        FTPHIS(unit,history, > status)
--
->4  Put (append) the DATE keyword into the CHU.  The keyword value will contain
-    the current system date as a character string in 'dd/mm/yy' format. If
-    a DATE keyword already exists in the header, then this subroutine will
->   simply update the keyword value in-place with the current date.
--
-        FTPDAT(unit, > status)
--
->5  Put (append) a new keyword of the appropriate datatype into the CHU. 
-    Note that FTPKYS will only write string values up to 68 characters in 
-    length; longer strings will be truncated.  The FTPKLS routine can be 
-    used to write longer strings, using a non-standard FITS convention.
-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the
-     precision.  This will suppress trailing zeros, and will use a
-     fixed format rather than an exponential format,
->    depending on the magnitude of the value.
--
-        FTPKY[JKLS](unit,keyword,keyval,comment, > status)
-        FTPKY[EDFG](unit,keyword,keyval,decimals,comment, > status)  
--
->6  Put (append) a string valued keyword into the CHU which may be longer 
-    than 68 characters in length.  This uses the Long String Keyword
-    convention that is described in the "Usage Guidelines and Suggestions"
-    section of this document.  Since this uses a non-standard FITS 
-    convention to encode the long keyword string, programs which use
-    this routine should also call the FTPLSW routine to add some COMMENT
-    keywords to warn users of the FITS file that this convention is
-    being used.  FTPLSW also writes a keyword called LONGSTRN to record
-    the version of the longstring convention that has been used, in case
-    a new convention is adopted at some point in the future.   If the
-    LONGSTRN keyword is already present in the header, then FTPLSW will
->   simply return and will not write duplicate keywords.
--
-        FTPKLS(unit,keyword,keyval,comment, > status)
-        FTPLSW(unit, > status)
--
->7  Put (append) a new keyword with an undefined, or null, value into the CHU.
->   The value string of the keyword is left blank in this case.
--
-        FTPKYU(unit,keyword,comment, > status)
--
->8  Put (append) a numbered sequence of keywords into the CHU.   One may
-    append the same comment to every keyword (and eliminate the need
-    to have an array of identical comment strings, one for each keyword) by
-    including the ampersand character as the last non-blank character in the
-    (first) COMMENTS string parameter.  This same string 
-    will then be used for the comment field in all the keywords. (Note
-    that the SPP version of these routines only supports a single comment
->   string).

-                   status)
--
->9 Copy an indexed keyword from one HDU to another, modifying
-    the index number of the keyword name in the process.  For example,
-    this routine could read the TLMIN3 keyword from the input HDU
-    (by giving keyroot = "TLMIN" and innum = 3) and write it to the
-    output HDU with the keyword name TLMIN4 (by setting outnum = 4).
-    If the input keyword does not exist, then this routine simply
->   returns without indicating an error. 
--
-        FTCPKY(inunit, outunit, innum, outnum, keyroot, > status)
--
->10 Put (append) a 'triple precision' keyword into the CHU in F28.16 format.
-    The floating point keyword value is constructed by concatenating the 
-    input integer value with the input double precision fraction value
-    (which must have a value between 0.0 and 1.0). The FTGKYT routine should 
-    be used to read this keyword value, because the other keyword reading
->   subroutines will not preserve the full precision of the value.
--
-        FTPKYT(unit,keyword,intval,dblval,comment, > status)

->11 Write keywords to the CHDU that are defined in an ASCII template file.
-   The format of the template file is described under the ftgthd
->  routine below. 
--
-        FTPKTP(unit, filename, > status)
--
->12 Append the physical units string to an existing keyword.  This

-***4.  Insert Keyword Subroutines \label{FTIREC}
-
->1  Insert a new keyword record into the CHU at the specified position
-    (i.e., immediately preceding the (keyno)th keyword in the header.)
-    This 'insert record' subroutine is somewhat less efficient
-    then the 'append record' subroutine (FTPREC) described above because
->   the remaining keywords in the header have to be shifted down one slot.
--
-        FTIREC(unit,key_no,card, > status)
--
->2  Insert a new keyword into the CHU.  The new keyword is inserted
-    immediately following the last keyword that has been read from the header.
-    The FTIKLS subroutine works the same as the FTIKYS subroutine, except
-    it also supports long string values greater than 68 characters in length.
-    These 'insert keyword' subroutines are somewhat less efficient then 
-    the 'append keyword' subroutines described above because the remaining
->   keywords in the header have to be shifted down one slot.

--
-***5.  Read Keyword Subroutines \label{FTGREC}
-
-These routines return the value of the specified keyword(s).  Wild card
-characters (*, ?, or \#) may be used when specifying the name of the keyword 
-to be read: a '?' will match any single character at that position in the
-keyword name and a '*' will match any length (including zero) string of
-characters.  The '\#' character will match any consecutive string of
-decimal digits (0 - 9). Note that when a wild card is used in the input 
-keyword name, the routine will only search for a match from the current 
-header position to the end of the header.  It will not resume the search 
-from the top of the header back to the original header position as is done
-when no wildcards are included in the keyword name.  If the desired
-keyword string is 8-characters long (the maximum length of a keyword
-name) then a '*' may be appended as the ninth character of the input
-name to force the keyword search to stop at the end of the header
-(e.g., 'COMMENT *' will search for the next COMMENT keyword).  The
-ffgrec routine may be used to set the starting position when doing
-wild card searches.
-
->1 Get the nth 80-character header record from the CHU.  The first keyword
-   in the header is at key\_no = 1;  if key\_no = 0 then this subroutine
-   simple moves the internal pointer to the beginning of the header
-   so that subsequent keyword operations will start at the top of 
->  the header; it also returns a blank card value in this case.
--
-        FTGREC(unit,key_no, > card,status)
--
->2  Get the name, value (as a string), and comment of the nth keyword in CHU.
-    This routine also checks that the returned keyword name (KEYWORD) contains
-    only legal ASCII characters.  Call FTGREC and FTPSVC to bypass this error
->   check.
--
-        FTGKYN(unit,key_no, > keyword,value,comment,status)
--
->>3  Get the 80-character header record for the named keyword
--
-        FTGCRD(unit,keyword, > card,status)
--
->4  Get the next keyword whose name matches one of the strings in
-    'inclist' but does not match any of the strings in 'exclist'.
-    The strings in inclist and exclist may contain wild card characters
-    (*, ?, and \#) as described at the beginning of this section.
-    This routine searches from the current header position to the
-    end of the header, only, and does not continue the search from
-    the top of the header back to the original position.  The current
-    header position may be reset with the ftgrec routine.  Note
-    that nexc may be set = 0 if there are no keywords to be excluded.
-    This routine returns status = 202 if a matching
->   keyword is not found.
--
-        FTGNXK(unit,inclist,ninc,exclist,nexc, > card,status)
--
->5   Get the literal keyword value as a character string.  Regardless
-     of the datatype of the keyword, this routine simply returns the
-     string of characters in the value field of the keyword along with
->    the comment field.
--
-        FTGKEY(unit,keyword, > value,comment,status) 
--
->6  Get a keyword value (with the appropriate datatype) and comment from 
->   the CHU

-        FTGKY[EDJKLS](unit,keyword, > keyval,comment,status)
--
->7  Get a sequence of numbered keyword values.  These
->   routines do not support wild card characters in the root name.
--
-        FTGKN[EDJKLS](unit,keyroot,startno,max_keys, > keyvals,nfound,status)
--
->8  Get the value of a floating point keyword, returning the integer and
-    fractional parts of the value in separate subroutine arguments.
-    This subroutine may be used to read any keyword but is especially
->   useful for reading the 'triple precision' keywords written by FTPKYT.
--
-        FTGKYT(unit,keyword, > intval,dblval,comment,status)
--
->9  Get the physical units string in an existing keyword.  This
-    routine uses a local convention, shown in the following example,
-    in which the keyword units are
-    enclosed in square brackets in the beginning of the keyword comment
-    field.  A blank string is returned if no units are defined
->    for the keyword.

->5  Modify the value and comment fields of an existing keyword in the CHU.
-    The FTMKLS subroutine works the same as the FTMKYS subroutine, except
-    it also supports long string values greater than 68 characters in length.
-    Optionally, one may modify only the value field and leave the comment
-    field unchanged by setting the input COMMENT parameter equal to
-    the ampersand character (\&).
-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the
-     precision.  This will suppress trailing zeros, and will use a

-
->1  Update an 80-character record in the CHU.  If the specified keyword
-    already exists then that header record will be replaced with 
-    the input CARD string.  If it does not exist then the new record will 
-    be added to the header.
-    The FTUKLS subroutine works the same as the FTUKYS subroutine, except
->   it also supports long string values greater than 68 characters in length.
--
-        FTUCRD(unit,keyword,card, > status)
--
->2  Update the value and comment fields of a keyword in the CHU.
-    The specified keyword is modified if it already exists (by calling
-    FTMKYx) otherwise a new keyword is created by calling FTPKYx.
-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the

-***8.  Delete Keyword Subroutines \label{FTDREC}
-
->1  Delete an existing keyword record.  The space previously occupied by  
-    the keyword is reclaimed by moving all the following header records up
-    one row in the header.  The first routine deletes a keyword at a
-    specified position in the header (the first keyword is at position 1),
-    whereas the second routine deletes a specifically named keyword.

-**F.  Data Scaling and Undefined Pixel Parameters  \label{FTPSCL}
-
-These subroutines define or modify the internal parameters used by
-FITSIO to either scale the data or to represent undefined pixels.
-Generally FITSIO will scale the data according to the values of the BSCALE
-and BZERO (or TSCALn and TZEROn) keywords, however these subroutines
-may be used to override the keyword values.  This may be useful when
-one wants to read or write the raw unscaled values in the FITS file.
-Similarly, FITSIO generally uses the value of the BLANK or TNULLn
-keyword to signify an undefined pixel, but these routines may be used
-to override this value.  These subroutines do not create or modify the
-corresponding header keyword values.
-
->1  Reset the scaling factors in the primary array or image extension; does 
-    not change the BSCALE and BZERO keyword values and only affects the
-    automatic scaling performed when the data elements are written/read
-    to/from the FITS file.   When reading from a FITS file the returned
-    data value = (the value given in the FITS array) * BSCALE + BZERO.
-    The inverse formula is used when writing data values to the FITS
-    file.  (NOTE: BSCALE and BZERO must be declared as Double Precision
->   variables).

-    value = (the value given in the FITS array) * TSCAL + TZERO.  The

-**G.  FITS Primary Array or IMAGE Extension I/O Subroutines \label{FTPPR}
-
-    These subroutines put or get data values in the primary data array
-(i.e., the first HDU in the FITS file) or an IMAGE extension.  The
-data array is represented as a single one-dimensional array of
-pixels regardless of the actual dimensionality of the array, and the
-FPIXEL parameter gives the position within this 1-D array of the first
-pixel to read  or write.  Automatic data type conversion is performed
-for numeric data (except for complex data types) if the data type of
-the primary array (defined by the BITPIX keyword) differs from the data
-type of the array in the calling subroutine.  The data values are also
-scaled by the BSCALE and BZERO header values as they are being written
-or read from the FITS array.  The ftpscl subroutine MUST be
-called to define the scaling parameters when writing data to the FITS
-array or to override the default scaling value given in the header when
-reading the FITS array.
-
-    Two sets of subroutines are provided to read the data array which
-differ in the way undefined pixels are handled.  The first set of
-routines (FTGPVx) simply return an array of data elements in which
-undefined pixels are set equal to a value specified by the user in the
-'nullval' parameter.  An additional feature of these subroutines is
-that if the user sets nullval = 0, then no checks for undefined pixels
-will be performed, thus increasing the speed of the program.  The
-second set of routines (FTGPFx) returns the data element array and, in
-addition, a logical array which defines whether the corresponding data
-pixel is undefined.  The latter set of subroutines may be more
-convenient to use in some circumstances, however, it requires an
-additional array of logical values which can be unwieldy when working
-with large data arrays.  Also for programmer convenience, sets of
-subroutines to directly read or write 2 and 3 dimensional arrays  have
-been provided, as well as a set of subroutines to read or write any
-contiguous rectangular subset of pixels within the n-dimensional array.
-
->1  Get the data type of the image (= BITPIX value).  Possible returned 
-    values are: 8, 16, 32, 64, -32, or -64 corresponding to unsigned byte,
-    signed 2-byte integer, signed 4-byte integer, signed 8-byte integer,
-    real, and double.
-
-    The second subroutine is similar to FTGIDT, except that if the image
-    pixel values are scaled, with non-default values for the BZERO and
-    BSCALE keywords, then this routine will return the 'equivalent'
-    data type that is needed to store the scaled values.  For example,
-    if BITPIX = 16 and BSCALE = 0.1 then the equivalent data type is
-    floating point, and -32 will be returned.  There are 2 special cases:
-    if the image contains unsigned 2-byte integer values, with BITPIX =
-    16, BSCALE = 1, and BZERO = 32768, then this routine will return
-    a non-standard value of 20 for the bitpix value.  Similarly if the
-    image contains unsigned 4-byte integers, then bitpix will
->   be returned with a value of 40.

-The following 4 subroutines transfer FITS images with 2 or 3 dimensions
-to or from a data array which has been declared in the calling program.  
-The dimensionality of the FITS image is passed by the naxis1, naxis2,
-and naxis3 parameters and the declared dimensions of the program array
-are passed in the dim1 and dim2 parameters.  Note that the program array
-does not have to have the same dimensions as the FITS array, but must
-be at least as big.  For example if a FITS image with NAXIS1 = NAXIS2 = 400
-is read into a program array which is dimensioned as 512 x 512 pixels,
-then the image will just fill the lower left corner of the array
-with pixels in the range 1 - 400 in the X an Y directions.  This has
-the effect of taking a contiguous set of pixel value in the FITS array
-and writing them to a non-contiguous array in program memory
-(i.e., there are now some blank pixels around the edge of the image

-The following subroutines transfer a rectangular subset of the pixels
-in a FITS N-dimensional image to or from an array which has been
-declared in the calling program.  The fpixels and lpixels parameters
-are integer arrays which specify the starting and ending pixels in each
-dimension of the FITS image that are to be read or written.  (Note that
-these are the starting and ending pixels in the FITS image, not in the
-declared array). The array parameter is treated simply as a large
-one-dimensional array of the appropriate datatype containing the pixel
-values; The pixel values in the FITS array are read/written  from/to
-this program array in strict sequence without any gaps;  it is up to
-the calling routine to correctly interpret the dimensionality of this
-array.  The two families of FITS reading routines (FTGSVx and FTGSFx
-subroutines) also have an 'incs' parameter which defines the
-data sampling interval in each dimension of the FITS array.  For
-example, if incs(1)=2 and incs(2)=3 when reading a 2-dimensional
-FITS image, then only every other pixel in the first dimension
-and every 3rd pixel in the second dimension will be returned in
-the 'array' parameter. [Note: the FTGSSx family of routines which
-were present in previous versions of FITSIO have been superseded
-by the more general FTGSVx family of routines.]

-**H.  FITS ASCII and Binary Table Data I/O Subroutines 
-
-***1.  Column Information Subroutines \label{FTGCNO}
-
->1   Get the number of rows or columns in the current FITS table.
-     The number of rows is given by the NAXIS2 keyword and the
-     number of columns is given by the TFIELDS keyword in the header
-     of the table.  The FTGNRWLL routine is identical to FTGNRW except
-     that the number of rows is returned as a 64-bit integer rather
->    than a 32-bit integer.
--
-        FTGNRW(unit, > nrows, status)
-        FTGNRWLL(unit, > nrowsll, status)
-        FTGNCL(unit, > ncols, status)
--
->2  Get the table column number (and name) of the column whose name
-matches an input template name.  The table column names are defined by
-the TTYPEn keywords in the FITS header.  If a column does not have a
-TTYPEn keyword, then these routines assume that the name consists of
-all blank characters.  These 2 subroutines perform the same function
-except that FTGCNO only returns the number of the matching column whereas
-FTGCNN also returns the name of the column.  If CASESEN = .true. then
-the column name match will be case-sensitive.
-
-The input column name template (COLTEMPLATE) is (1) either the exact
-name of the column to be searched for, or (2) it may contain wild cards
-characters (*, ?, or \#), or (3) it may contain the number of the desired
-column (where the number is expressed as ASCII digits).  The first 2 wild 
-cards behave similarly to UNIX filename matching:  the '*' character matches 
-any sequence of characters (including zero characters) and the '?'
-character matches any single character.  The \# wildcard will match
-any consecutive string of decimal digits (0-9).  As an example, the template
-strings 'AB?DE', 'AB*E', and 'AB*CDE' will all match the string
-'ABCDE'.  If more than one column name in the table matches the
-template string, then the first match is returned and the status value
-will be set to 237 as a warning that a unique match was not found.  To
-find the other cases that match the template, simply call the
-subroutine again leaving the input status value equal to  237 and the
-next matching name will then be returned.  Repeat this process until a
-status = 219 (column name not found) is returned.  If these subroutines
-fail to match the template to any of the columns in the table, they
-lastly check if the template can be interpreted as a simple positive
-integer (e.g., '7', or '512') and if so, they return that column
-number.  If no matches are found then a status = 219 error is
-returned.
-
-Note that the FITS Standard recommends that only letters, digits, and
-the underscore character be used in column names (with no embedded
->spaces in the name).  Trailing blank characters are not significant.

-        FTGCNN(unit,casesen,coltemplate, > colname,colnum,status)
--
->3  Get the datatype of a column in an ASCII or binary table.  This 
-    routine returns an integer code value corresponding to the datatype
-    of the column. (See the FTBNFM and FTASFM subroutines in the Utilities
-    section of this document for a list of the code values).  The vector
-    repeat count (which is alway 1 for ASCII table columns) is also returned.
-    If the specified column has an ASCII character datatype (code = 16) then
-    the width of a unit string in the column is also returned.  Note that
-    this routine supports the local convention for specifying arrays of
-    strings within a binary table character column, using the syntax 
-    TFORM = 'rAw' where 'r' is the total number of characters (= the width 
-    of the column) and 'w' is the width of a unit string within the column.  
-    Thus if the column has TFORM = '60A12' then this routine will return 
-    datacode = 16, repeat = 60, and width = 12.  (The TDIMn
-    keyword may also be used to specify the unit string length; The pair
-    of keywords TFORMn = '60A' and TDIMn = '(12,5)'  would have the
-    same effect as TFORMn = '60A12').
-
-   The second routine, FTEQTY is similar except that in
-   the case of scaled integer columns it returns the 'equivalent' data
-   type that is needed to store the scaled values, and not necessarily
-   the physical data type of the unscaled values as stored in the FITS
-   table.  For example if a '1I' column in a binary table has TSCALn =
-   1 and TZEROn = 32768, then this column effectively contains unsigned
-   short integer values, and thus the returned value of typecode will
-   be the code for an unsigned short integer, not a signed short integer.
-   Similarly, if a column has TTYPEn = '1I'
-   and TSCALn = 0.12, then the returned typecode
->  will be the code for a 'real' column.

->4  Return the display width of a column.  This is the length
-    of the string that will be returned  
-    when reading the column as a formatted string.  The display width is
-    determined by the TDISPn keyword, if present, otherwise by the data
->   type of the column.

->6  Get information about an existing binary table column. (NOTE: TSCAL and
-    TZERO must be declared as Double Precision variables). DATATYPE is a 
-    character string which returns the datatype of the column as defined
-    by the TFORMn keyword (e.g., 'I', 'J','E', 'D', etc.).  In the case
-    of an ASCII character column, DATATYPE will have a value of the 
-    form 'An' where 'n' is an integer expressing the width of the field
-    in characters.  For example, if TFORM = '160A8' then FTGBCL will return
-    DATATYPE='A8' and REPEAT=20.   All the returned parameters are scalar
->   quantities.

-***2.  Low-Level Table Access Subroutines \label{FTGTBS}
-
-The following subroutines provide low-level access to the data in ASCII
-or binary tables and are mainly useful as an efficient way to copy all
-or part of a table from one location to another.  These routines simply
-read or write the specified number of consecutive bytes in an ASCII or
-binary table, without regard for column boundaries or the row length in
-the table.  The first two subroutines read or write consecutive bytes
-in a table to or from a character string variable, while the last two
-subroutines read or write consecutive bytes to or from a variable
-declared as a numeric data type (e.g., INTEGER, INTEGER*2, REAL, DOUBLE
-PRECISION).  These routines do not perform any machine dependent data
-conversion or byte swapping, except that conversion to/from ASCII
-format is performed by the FTGTBS and FTPTBS routines on machines which
-do not use ASCII character codes in the internal data representations
-(e.g., on IBM mainframe computers).
-
->1  Read a consecutive string of characters from an ASCII table 
-    into a character variable (spanning columns and multiple rows if necessary)

->1  Insert blank rows into an existing ASCII or binary table (in the CDU).
-    All the rows FOLLOWING row FROW are shifted down by NROWS rows.  If
-    FROW or FROWLL equals 0 then the blank rows are inserted at the beginning of the 
-    table.  These routines modify the NAXIS2 keyword to reflect the new 
-    number of rows in the table.  Note that it is *not* necessary to insert rows in a table before
-    writing data to those rows (indeed, it would be inefficient to do so).
-    Instead, one may simply write data to any row of the table, whether that
->   row of data already exists or not.

->2  Delete rows from an existing ASCII or binary table (in the CDU).
-    The NROWS (or NROWSLL) is the number of rows are deleted, starting 
-    with row FROW (or FROWLL), and
-    any remaining rows in the table are shifted up to fill in the space.
-    These routines modify the NAXIS2 keyword to reflect the new number

-    In the first routine, 'rowrange' is a character string listing the
-    rows or row ranges to delete (e.g., '2-4, 5, 8-9'). In the second
-    routine, 'rowlist' is an integer array of row numbers to be deleted
-    from the table.  nrows is the number of row numbers in the list.
-    The first row in the table is 1 not 0.  The list of row numbers

-        FTDRWS(unit,rowlist,nrows, > status)
--
->4  Insert a blank column (or columns) into an existing ASCII or binary 
-    table (in the CDU).  COLNUM specifies the column number that the (first)
-    new column should occupy in the table.  NCOLS specifies how many 
-    columns are to be inserted. Any existing columns from this position and
-    higher are moved over to allow room for the new column(s).  
-    The index number on all the following keywords will be incremented
-    if necessary to reflect the new position of the column(s) in the table:
-    TBCOLn, TFORMn, TTYPEn, TUNITn, TNULLn, TSCALn, TZEROn, TDISPn, TDIMn,

->6  Delete a column from an existing ASCII or binary table (in the CDU).
-    The index number of all the keywords listed above (for FTICOL) will be

-***4.  Read and Write Column Data Routines \label{FTPCLS}
-
-These subroutines put or get data values in the current ASCII or Binary table
-extension.  Automatic data type conversion is performed for numerical data
-types (B,I,J,E,D) if the data type of the column (defined by the TFORM keyword)
-differs from the data type of the calling subroutine.  The data values are also
-scaled by the TSCALn and TZEROn header values as they are being written to
-or read from the FITS array.  The fttscl subroutine MUST be used to define the
-scaling parameters when writing data to the table or to override the default
-scaling values given in the header when reading from the table. 
-Note that it is *not* necessary to insert rows in a table before
-writing data to those rows (indeed, it would be inefficient to do so).
-Instead, one may simply write data to any row of the table, whether that
-row of data already exists or not.
-
-    In the case of binary tables with vector elements, the 'felem'
-parameter defines the starting pixel within the element vector.  This
-parameter is ignored with ASCII tables. Similarly, in the case of
-binary tables the 'nelements' parameter specifies the total number of
-vector values read or written (continuing on subsequent rows if
-required) and not the number of table elements.  Two sets of
-subroutines are provided to get the column data which differ in the way
-undefined pixels are handled.  The first set of routines (FTGCV)
-simply return an array of data elements in which undefined pixels are
-set equal to a value specified by the user in the 'nullval' parameter.
-An additional feature of these subroutines is that if the user sets
-nullval = 0, then no checks for undefined pixels will be performed,
-thus increasing the speed of the program.  The second set of routines
-(FTGCF) returns the data element array and in addition a logical array
-of flags which defines whether the corresponding data pixel is undefined.
-
-    Any column, regardless of it's intrinsic datatype, may be read as a
-    string.  It should be noted however that reading a numeric column
-    as a string is 10 - 100 times slower than reading the same column as
-    a number due to the large overhead in constructing the formatted
-    strings.    The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    datatype of the column.  The length of the returned strings can be
-    determined with the ftgcdw routine.  The following TDISPn display
-    formats are currently supported:
--
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
--
-  where w is the width in characters of the displayed values, m is the minimum
-  number of digits displayed, and d is the number of digits to the right of the 
-  decimal.  The .m field is optional.

-**I.  Row Selection and Calculator Routines \label{FTFROW}
-
-These routines all parse and evaluate an input string containing a user
-defined arithmetic expression.  The first 3 routines select rows in a
-FITS table, based on whether the expression evaluates to true (not
-equal to zero) or false (zero).  The other routines evaluate the
-expression and calculate a value for each row of the table.  The
-allowed expression syntax is described in the row filter section in the
-earlier `Extended File Name Syntax' chapter of this document.  The
-expression may also be written to a text file, and the name of the
-file, prepended with a '@' character may be supplied for the 'expr'
-parameter (e.g.  '@filename.txt'). The  expression  in  the  file can
-be arbitrarily complex and extend over multiple lines of the file.
-Lines  that begin with 2 slash characters ('//') will  be ignored and
-may be used to add comments to the file.
-

-exist) into which to write the results, and parInfo contains an
-optional TFORM keyword value if a new column is being created.  If a
-TFORM value is not specified then a default format will be used,

-**J.  Celestial Coordinate System Subroutines \label{FTGICS}
-
-The FITS community has adopted a set of keyword conventions that define
-the transformations needed to convert between pixel locations in an
-image and the corresponding celestial coordinates on the sky, or more
-generally, that define world coordinates that are to be associated with
-any pixel location in an n-dimensional FITS array. CFITSIO is distributed
-with a couple of self-contained World Coordinate System (WCS) routines,
-however, these routines DO NOT support all the latest WCS conventions,
-so it is STRONGLY RECOMMENDED that software developers use a more robust
-external WCS library.  Several recommended libraries are:
--
-  WCSLIB -  supported by Mark Calabretta
-  WCSTools - supported by Doug Mink
-  AST library - developed by the U.K. Starlink project
--
-
-More information about the WCS keyword conventions and links to all of
-these WCS libraries can be found on the FITS Support Office web site at
-http://fits.gsfc.nasa.gov under the WCS link.
-
-The functions provided in these external WCS libraries will need access to
-the  WCS information contained in the FITS file headers.  One convenient
-way to pass this information to the external library is to use  FITSIO
-to copy the header keywords into one long character string, and then
-pass this string to an interface routine in the external library that
-will extract the necessary WCS information (e.g., see the astFitsChan
-and astPutCards routines in the Starlink AST library).
-
-The following FITSIO routines DO NOT support the more recent WCS conventions
-that have been approved as part of the FITS standard.  Consequently,
-the following routines ARE NOW DEPRECATED.  It is STRONGLY RECOMMENDED
-that software developers not use these routines, and instead use an
-external WCS library, as described above.
-
-These routines are included mainly for backward compatibility with
-existing software.  They support the following standard map 
-projections: -SIN, -TAN, -ARC, -NCP, -GLS, -MER, and -AIT (these are the
-legal values for the coordtype parameter).  These routines are based
-on similar functions in Classic AIPS.  All the angular quantities are
-given in units of degrees.
-
->1  Get the values of all the standard FITS celestial coordinate system
-    keywords from the header of a FITS image (i.e., the primary array or
-    an image extension).  These values may then be passed to the subroutines
-    that perform the coordinate transformations.  If any or all of the WCS 
-    keywords are not present, then default values will be returned. If
-    the first coordinate axis is the declination-like coordinate, then
-    this routine will swap them so that the longitudinal-like coordinate
-    is returned as the first axis.
-
-    If the file uses the newer 'CDj\_i' WCS transformation matrix
-    keywords instead of old style 'CDELTn' and 'CROTA2' keywords, then
-    this routine will calculate and return the values of the equivalent
-    old-style keywords.    Note that the conversion from the new-style
-    keywords to the old-style values is sometimes only an
-    approximation, so if the approximation is larger than an internally
-    defined threshold level, then CFITSIO will still return the
-    approximate WCS keyword values, but will also return with status =
-    506, to warn the calling program that approximations have been
-    made.  It is then up to the calling program to decide whether the
-    approximations are sufficiently accurate for the particular
-    application, or whether more precise WCS transformations must be
->   performed using new-style WCS keywords directly.

-**K.  File Checksum Subroutines \label{FTPCKS}
-
-The following routines either compute or validate the checksums for the
-CHDU.  The DATASUM keyword is used to store the numerical value of the
-32-bit, 1's complement checksum for the data unit alone.  If there is
-no data unit then the value is set to zero. The numerical value is
-stored as an ASCII string of digits, enclosed in quotes, because the
-value may be too large to represent as a 32-bit signed integer.  The
-CHECKSUM keyword is used to store the ASCII encoded COMPLEMENT of the
-checksum for the entire HDU.  Storing the complement, rather than the
-actual checksum, forces the checksum for the whole HDU to equal zero.
-If the file has been modified since the checksums were computed, then
-the HDU checksum will usually not equal zero.  These checksum keyword
-conventions are based on a paper by Rob Seaman published in the
-proceedings of the ADASS IV conference in Baltimore in November 1994
-and a later revision in June 1995.
-
->1  Compute and write the DATASUM and CHECKSUM keyword values for the CHDU
-    into the current header.  The DATASUM value is the 32-bit checksum
-    for the data unit, expressed as a decimal integer enclosed in single 
-    quotes. The CHECKSUM keyword value is a 16-character string which
-    is the ASCII-encoded value for the complement of the checksum for 
-    the whole HDU.  If these keywords already exist, their values
-    will be updated only if necessary (i.e., if the file has been modified 
->   since the original keyword values were computed).
--
-        FTPCKS(unit, > status) 
--
->2  Update the CHECKSUM keyword value in the CHDU, assuming that the
-    DATASUM keyword exists and already has the correct value.  This routine
-    calculates the new checksum for the current header unit, adds it to the 
-    data unit checksum, encodes the value into an ASCII string, and writes
->   the string to the CHECKSUM keyword.
--
-        FTUCKS(unit, > status) 
--
->3  Verify the CHDU by computing the checksums and comparing
-    them with the keywords.  The data unit is verified correctly
-    if the computed checksum equals the value of the DATASUM
-    keyword.  The checksum for the entire HDU (header plus data unit) is 
-    correct if it equals zero.  The output DATAOK and HDUOK parameters
-    in this subroutine are integers which will have a value = 1
-    if the data or HDU is verified correctly, a value = 0
-    if the DATASUM or CHECKSUM keyword is not present, or value = -1

-
->2  Get the current system date and time string ('YYYY-MM-DDThh:mm:ss').
-The time will be in UTC/GMT if available, as indicated by a returned timeref 
-value = 0.  If the returned value of timeref = 1 then this indicates that
-it was not possible to convert the local time to UTC, and thus the local
->time was returned.
--
-        FTGSTM(> datestr, timeref, status)
--
-
->3  Construct a date string from the input date values.  If the year
-is between 1900 and 1998, inclusive, then the returned date string will
-have the old FITS format ('dd/mm/yy'), otherwise the date string will
-have the new FITS format ('YYYY-MM-DD').  Use FTTM2S instead
-> to always return a date string using the new FITS format. 
--
-        FTDT2S( year, month, day, > datestr, status)
--
-
->4  Construct a new-format date + time string ('YYYY-MM-DDThh:mm:ss.ddd...').
-  If the year, month, and day values all = 0 then only the time is encoded
-  with format 'hh:mm:ss.ddd...'.  The decimals parameter specifies how many
-  decimal places of fractional seconds to include in the string.  If `decimals'
-> is negative, then only the date will be return ('YYYY-MM-DD').
--
-        FTTM2S( year, month, day, hour, minute, second, decimals, 
-                > datestr, status)
--
-
->5  Return the date as read from the input string, where the string may be
-in either the old ('dd/mm/yy')  or new ('YYYY-MM-DDThh:mm:ss' or
->'YYYY-MM-DD') FITS format.  
--
-        FTS2DT(datestr, > year, month, day, status)
--
-
->6  Return the date and time as read from the input string, where the
-string may be in either the old  or new FITS format.  The returned hours,
-minutes, and seconds values will be set to zero if the input string
-does not include the time ('dd/mm/yy' or 'YYYY-MM-DD') .  Similarly,
-the returned year, month, and date values will be set to zero if the
->date is not included in the input string ('hh:mm:ss.ddd...'). 
--
-        FTS2TM(datestr, > year, month, day, hour, minute, second, status)

-**M.  General Utility Subroutines \label{FTGHAD}
-
-The following utility subroutines may be useful for certain applications:
-
->>1  Return the starting byte address of the CHDU and the next HDU.
--
-        FTGHAD(iunit, > curaddr, nextaddr)
--
->>2  Convert a character string to uppercase (operates in place).
--
-        FTUPCH(string)
--
->3  Compare the input template string against the reference string
-    to see if they match.  The template string may contain wildcard
-    characters: '*' will match any sequence of characters (including
-    zero characters) and '?' will match any single character in the
-    reference string. The '\#' character will match any consecutive string
-    of decimal digits (0 - 9).  If CASESN = .true. then the match will be
-    case sensitive.  The returned MATCH parameter will be .true. if
-    the 2 strings match, and EXACT will be .true. if the match is
-    exact (i.e., if no wildcard characters were used in the match).
->   Both strings must be 68 characters or less in length.
--
-        FTCMPS(str_template, string, casesen, > match, exact)
--
-
->4  Test that the keyword name contains only legal characters: A-Z,0-9,
->   hyphen, and underscore.
--
-        FTTKEY(keyword, > status)
--
->5  Test that the keyword record contains only legal printable ASCII
->     characters
--
-        FTTREC(card, > status)
--
->6  Test whether the current header contains any NULL (ASCII 0) characters.
-    These characters are illegal in the header, but they will go undetected
-    by most of the CFITSIO keyword header routines, because the null is 
-    interpreted as the normal end-of-string terminator.  This routine returns
-    the position of the first null character in the header, or zero if there
-    are no nulls.  For example a returned value of 110 would indicate that
-    the first NULL is located in the 30th character of the second keyword
-    in the header (recall that each header record is 80 characters long).
-    Note that this is one of the few FITSIO routines in which the returned
->   value is not necessarily equal to the status value).   
--
-        FTNCHK(unit, > status)
--
->7  Parse a header keyword record and return the name of the keyword
-    and the length of the name.
-    The keyword name normally occupies the first 8 characters of the
-    record, except under the HIERARCH convention where the name can
->   be up to 70 characters in length.
--
-        FTGKNM(card, > keyname, keylength, staThe '\#' character will match any consecutive string
-    of decimal digits (0 - 9). tus)
--  
->8  Parse a header keyword record.
-    This subroutine parses the input header record to return the value (as
-    a character string) and comment strings.  If the keyword has no
-    value (columns 9-10 not equal to '= '), then the value string is returned
-    blank and the comment string is set equal to column 9 - 80 of the
->   input string.
--
-        FTPSVC(card, > value,comment,status)
--
->9  Construct a sequence keyword name (ROOT + nnn).
-    This subroutine appends the sequence number to the root string to create
->   a keyword name (e.g., 'NAXIS' + 2 = 'NAXIS2')
--
-        FTKEYN(keyroot,seq_no, > keyword,status)
--
->10 Construct a sequence keyword name (n + ROOT).
-    This subroutine concatenates the sequence number to the front of the
->   root string to create a keyword name (e.g., 1 + 'CTYP' = '1CTYP')
--
-        FTNKEY(seq_no,keyroot, > keyword,status)
--
->11 Determine the datatype of a keyword value string.
-    This subroutine parses the keyword value string (usually columns 11-30
->   of the header record) to determine its datatype.  
--
-        FTDTYP(value, > dtype,status)
--
->11 Return the class of input header record.  The record is classified
-    into one of the following categories (the class values are
-    defined in fitsio.h).  Note that this is one of the few FITSIO
->   routines that does not return a status value.

->12 Parse the 'TFORM' binary table column format string.
-    This subroutine parses the input TFORM character string and returns the
-    integer datatype code, the repeat count of the field, and, in the case
-    of character string fields, the length of the unit string.  The following
-    datatype codes are returned (the negative of the value is returned

--
-                Datatype                DATACODE value

-        FTBNFM(tform, > datacode,repeat,width,status)
--
->13 Parse the 'TFORM' keyword value that defines the column format in
-    an ASCII table.  This routine parses the input TFORM character
-    string and returns the datatype code, the width of the column,
-    and (if it is a floating point column) the number of decimal places
-    to the right of the decimal point.  The returned datatype codes are
-    the same as for the binary table, listed above, with the following
-    additional rules:  integer columns that are between 1 and 4 characters
-    wide are defined to be short integers (code = 21).  Wider integer
-    columns are defined to be regular integers (code = 41).  Similarly,
-    Fixed decimal point columns (with TFORM = 'Fw.d') are defined to
-    be single precision reals (code = 42) if w is between 1 and 7 characters
-    wide, inclusive.  Wider 'F' columns will return a double precision
-    data code (= 82).  'Ew.d' format columns will have datacode = 42,
->   and 'Dw.d' format columns will have datacode = 82.
--
-        FTASFM(tform, > datacode,width,decimals,status)
--
->14 Calculate the starting column positions and total ASCII table width
-    based on the input array of ASCII table TFORM values.  The SPACE input
-    parameter defines how many blank spaces to leave between each column
-    (it is recommended to have one space between columns for better human
->   readability).
--
-        FTGABC(tfields,tform,space, > rowlen,tbcol,status)
--
->15 Parse a template string and return a formatted 80-character string
-    suitable for appending to (or deleting from) a FITS header file.  
-    This subroutine is useful for parsing lines from an ASCII template file
-    and reformatting them into legal FITS header records.  The formatted
-    string may then be passed to the FTPREC, FTMCRD, or FTDKEY subroutines 
->   to append or modify a FITS header record.
--
-        FTGTHD(template, > card,hdtype,status)
--
-    The input TEMPLATE character string generally should contain 3 tokens:
-    (1) the KEYNAME, (2) the VALUE, and (3) the COMMENT string.  The
-    TEMPLATE string must adhere to the following format:
-
->-      The KEYNAME token must begin in columns 1-8 and be a maximum  of 8
-        characters long.  If the first 8 characters of the template line are
-        blank then the remainder of the line is considered to be a FITS comment
-        (with a blank keyword name).  A legal FITS keyword name may only
-        contain the characters A-Z, 0-9, and '-' (minus sign) and
-        underscore.  This subroutine will automatically convert any lowercase
-        characters to uppercase in the output string.  If KEYNAME = 'COMMENT'
-        or 'HISTORY' then the remainder of the line is considered to be a FITS
->       COMMENT or HISTORY record, respectively.
-
->-      The VALUE token must be separated from the KEYNAME token by one or more
-        spaces and/or an '=' character.  The datatype of the VALUE token
-        (numeric, logical, or character string) is automatically determined
-        and  the output CARD string is formatted accordingly.  The value
-        token may be forced to be interpreted as a string (e.g. if it is a
-        string of numeric digits) by enclosing it in single quotes.
-        If the value token is a character string that contains 1 or more 
-        embedded blank space characters or slash ('/') characters then the 
->       entire character string must be enclosed in single quotes.
-
->-      The COMMENT token is optional, but if present must be separated from
->       the VALUE token by a blank space or a  '/' character.
-
->-      One exception to the above rules is that if the first non-blank
-        character in the template string is a minus sign ('-') followed
-        by a single token, or a single token followed by an equal sign, 
-        then it is interpreted as the name of a keyword which is to be  
->       deleted from the FITS header.  
-
->-      The second exception is that if the template string starts with
-        a minus sign and is followed by 2 tokens then the second token
-        is interpreted as the new name for the keyword specified by
-        first token.  In this case the old keyword name (first token)
-        is returned in characters 1-8 of the returned CARD string, and
-        the new keyword name (the second token) is returned in characters
-        41-48 of the returned CARD string.  These old and new names
-        may then be passed to the FTMNAM subroutine which will change
->       the keyword name.
-
-    The HDTYPE output parameter indicates how the returned CARD string
-    should be interpreted:
--
-        hdtype                  interpretation
-        ------           -------------------------------------------------
-           -2            Modify the name of the keyword given in CARD(1:8)
-                         to the new name given in CARD(41:48)
-
-           -1            CARD(1:8) contains the name of a keyword to be deleted
-                         from the FITS header.
-
-            0            append the CARD string to the FITS header if the
-                         keyword does not already exist, otherwise update
-                         the value/comment if the keyword is already present
-                         in the header.
-
-            1            simply append this keyword to the FITS header (CARD
-                         is either a HISTORY or COMMENT keyword).
-
-            2            This is a FITS END record; it should not be written
-                         to the FITS header because FITSIO automatically
-                         appends the END record when the header is closed.
--
-     EXAMPLES:  The following lines illustrate valid input template strings:
--
-      INTVAL 7 This is an integer keyword
-      RVAL           34.6   /     This is a floating point keyword
-      EVAL=-12.45E-03  This is a floating point keyword in exponential notation
-      lval F This is a boolean keyword
-                  This is a comment keyword with a blank keyword name
-      SVAL1 = 'Hello world'   /  this is a string keyword
-      SVAL2  '123.5'  this is also a string keyword
-      sval3  123+  /  this is also a string keyword with the value '123+    '
-      # the following template line deletes the DATE keyword
-      - DATE 
-      # the following template line modifies the NAME keyword to OBJECT
-      - NAME OBJECT
--                
->16  Parse the input string containing a list of rows or row ranges, and
-     return integer arrays containing the first and last row in each
-     range.  For example, if rowlist = "3-5, 6, 8-9" then it will
-     return numranges = 3, rangemin = 3, 6, 8 and rangemax = 5, 6, 9.
-     At most, 'maxranges' number of ranges will be returned.  'maxrows'
-     is the maximum number of rows in the table; any rows or ranges
-     larger than this will be ignored.  The rows must be specified in
-     increasing order, and the ranges must not overlap. A minus sign
-     may be use to specify all the rows to the upper or lower bound, so
-     "50-" means all the rows from 50 to the end of the table, and "-"
->    means all the rows in the table, from 1 - maxrows.

-*VI.  The CFITSIO Iterator Function
-
-The fits\_iterate\_data function in CFITSIO provides a unique method of
-executing an arbitrary user-supplied `work' function that operates on
-rows of data in  FITS tables or on pixels in FITS images.  Rather than
-explicitly reading and writing the FITS images or columns of data, one
-instead calls the CFITSIO iterator routine, passing to it the name of
-the user's work function that is to be executed along with a list of
-all the table columns or image arrays that are to be passed to the work
-function.  The CFITSIO iterator function then does all the work of
-allocating memory for the arrays, reading the input data from the FITS
-file, passing them to the work function, and then writing any output
-data back to the FITS file after the work function exits.  Because
-it is often more efficient to process only a subset of the total table
-rows at one time, the iterator function can determine the optimum
-amount of data to pass in each iteration and repeatedly call the work
-function until the entire table been processed.
-
-For many applications this single CFITSIO iterator function can
-effectively replace all the other CFITSIO routines for reading or
-writing data in FITS images or tables.  Using the iterator has several
-important advantages over the traditional method of reading and writing
-FITS data files:
-
-\begin{itemize}
-\item
-It cleanly separates the data I/O from the routine that operates on
-the data.  This leads to a more modular and `object oriented'
-programming style.  
-
-\item
-It simplifies the application program by eliminating the need to allocate
-memory for the data arrays and eliminates most of the calls to the CFITSIO
-routines that explicitly read and write the data.
-
-\item
-It ensures that the data are processed as efficiently as possible.
-This is especially important when processing tabular data since
-the iterator function will calculate the most efficient number
-of rows in the table to be passed at one time to the user's work 
-function on each iteration.
-
-\item
-Makes it possible for larger projects to develop a library of work
-functions that all have a uniform calling sequence and are all
-independent of the details of the FITS file format.
-
-\end{itemize}
-
-There are basically 2 steps in using the CFITSIO iterator function.
-The first step is to design the work function itself which must have a
-prescribed set of input parameters.  One of these parameters is a
-structure containing pointers to the arrays of data; the work function
-can perform any desired operations on these arrays and does not need to
-worry about how the input data were read from the file or how the
-output data get written back to the file.
-
-The second step is to design the driver routine that opens all the
-necessary FITS files and initializes  the input parameters to the
-iterator function.  The driver program calls the CFITSIO iterator
-function which then reads the data and passes it to the user's work
-function.
-
-Further details on using the iterator function can be found in the
-companion CFITSIO User's Guide, and in the iter\_a.f, iter\_b.f and
-iter\_c.f example programs.

-
-*IV.   Extended File Name Syntax
-
-**A.  Overview
-
-CFITSIO supports an extended syntax when specifying the name of the
-data file to be opened or created  that includes the following
-features:
-
-\begin{itemize}
-\item
-CFITSIO can read IRAF format images which have header file names that
-end with the '.imh' extension, as well as reading and writing FITS
-files,   This feature is implemented in CFITSIO by first converting the
-IRAF image into a temporary FITS format file in memory, then opening
-the FITS file.  Any of the usual CFITSIO routines then may be used to
-read the image header or data.  Similarly, raw binary data arrays can
-be read by converting them on the fly into virtual FITS images.
-
-\item
-FITS files on the Internet can be read (and sometimes written) using the FTP,
-HTTP, or ROOT protocols.
-
-\item
-FITS files can be piped between tasks on the stdin and stdout streams.
-
-\item
-FITS files can be read and written in shared memory.  This can potentially
-achieve much better data I/O performance compared to reading and
-writing the same FITS files on magnetic disk.
-
-\item
-Compressed FITS files in gzip or Unix COMPRESS format can be directly read.
-
-\item
-Output FITS files can be written directly in compressed gzip format,
-thus saving disk space.
-
-\item
-FITS table columns can be created, modified, or deleted 'on-the-fly' as
-the table is opened by CFITSIO.  This creates a virtual FITS file containing
-the modifications that is then opened by the application program.
-
-\item
-Table rows may be selected, or filtered out, on the fly when the table
-is opened by CFITSIO, based on an arbitrary user-specified expression.
-Only rows for which the expression evaluates to 'TRUE' are retained
-in the copy of the table that is opened by the application program.
-
-\item
-Histogram images may be created on the fly by binning the values in
-table columns, resulting in a virtual N-dimensional FITS image.  The
-application program then only sees the FITS image (in the primary
-array) instead of the original FITS table.
-\end{itemize}
-
-The latter 3 features in particular add very powerful data processing
-capabilities directly into CFITSIO, and hence into every task that uses
-CFITSIO to read or write FITS files.  For example, these features
-transform a very simple program that just copies an input FITS file to
-a new output file (like the `fitscopy' program that is distributed with
-CFITSIO) into a multipurpose FITS file processing tool.  By appending
-fairly simple qualifiers onto the name of the input FITS file, the user
-can perform quite complex table editing operations (e.g., create new
-columns, or filter out rows in a table) or create FITS images by
-binning or histogramming the values in table columns.  In addition,
-these functions have been coded using new state-of-the art algorithms
-that are, in some cases, 10 - 100 times faster than previous widely
-used implementations.
-
-Before describing the complete syntax for the extended FITS file names
-in the next section, here are a few examples of FITS file names that
-give a quick overview of the allowed syntax:
-
-\begin{itemize}
-\item
-{\tt 'myfile.fits'}: the simplest case of a FITS file on disk in the current
-directory.
-
-\item
-{\tt 'myfile.imh'}: opens an IRAF format image file and converts it on the
-fly into a temporary FITS format image in memory which can then be read with
-any other CFITSIO routine.
-
-\item
-{\tt rawfile.dat[i512,512]}: opens a raw binary data array (a 512 x 512
-short integer array in this case) and converts it on the fly into a
-temporary FITS format image in memory which can then be read with any
-other CFITSIO routine.
-
-\item
-{\tt myfile.fits.gz}: if this is the name of a new output file, the '.gz'
-suffix will cause it to be compressed in gzip format when it is written to 
-disk.
-
-\item
-{\tt 'myfile.fits.gz[events, 2]'}:  opens and uncompresses the gzipped file
-myfile.fits then moves to the extension which has the keywords EXTNAME
-= 'EVENTS' and EXTVER = 2.
-
-\item
-{\tt '-'}:  a dash (minus sign) signifies that the input file is to be read
-from the stdin file stream, or that the output file is to be written to
-the stdout stream. 
-
-\item
-{\tt 'ftp://legacy.gsfc.nasa.gov/test/vela.fits'}:  FITS files in any ftp
-archive site on the Internet may be directly opened with read-only
-access.
-
-\item
-{\tt 'http://legacy.gsfc.nasa.gov/software/test.fits'}: any valid URL to a
-FITS file on the Web may be opened with read-only access.
-
-\item
-{\tt 'root://legacy.gsfc.nasa.gov/test/vela.fits'}: similar to ftp access
-except that it provides write as well as read access to the files
-across the network. This uses the root protocol developed at CERN.
-
-\item
-{\tt 'shmem://h2[events]'}: opens the FITS file in a shared memory segment and
-moves to the EVENTS extension.  
-
-\item
-{\tt 'mem://'}:  creates a scratch output file in core computer memory.  The
-resulting 'file' will disappear when the program exits, so this
-is mainly useful for testing purposes when one does not want a
-permanent copy of the output file.
-
-\item
-{\tt 'myfile.fits[3; Images(10)]'}: opens a copy of the image contained in the
-10th row of the 'Images' column in the binary table in the 3th extension
-of the FITS file.  The application just sees this single image as the 
-primary array.
-
-\item
-{\tt 'myfile.fits[1:512:2, 1:512:2]'}: opens a section of the input image
-ranging from the 1st to the 512th pixel in  X and Y, and selects every 
-second pixel in both dimensions, resulting in a 256 x 256 pixel image 
-in this case.
-
-\item
-{\tt 'myfile.fits[EVENTS][col Rad = sqrt(X**2 + Y**2)]'}:  creates and opens
-a temporary file on the fly (in memory or on disk) that is identical to
-myfile.fits except that it will contain a new column in the EVENTS
-extension called 'Rad' whose value is computed using the indicated
-expression which is a function of the values in the X and Y columns.
-
-\item
-{\tt 'myfile.fits[EVENTS][PHA > 5]'}:  creates and opens a temporary FITS
-files that is identical to 'myfile.fits' except that the EVENTS table
-will only contain the rows that have values of the PHA column greater
-than 5.  In general, any arbitrary boolean expression using a C or
-Fortran-like syntax, which may combine AND and OR operators,
-may be used to select rows from a table.
-
-\item
-{\tt 'myfile.fits[EVENTS][bin (X,Y)=1,2048,4]'}:  creates a temporary FITS
-primary array image which is computed on the fly by binning (i.e,
-computing the 2-dimensional histogram) of the values in the X and Y
-columns of the EVENTS extension.  In this case the X and Y coordinates
-range from 1 to 2048 and the image pixel size is 4 units in both
-dimensions, so the resulting image is 512 x 512 pixels in size.
-
-\item
-The final example combines many of these feature into one complex
-expression (it is broken into several lines for clarity):
--
-  'ftp://legacy.gsfc.nasa.gov/data/sample.fits.gz[EVENTS]
-   [col phacorr = pha * 1.1 - 0.3][phacorr >= 5.0 && phacorr <= 14.0]
-   [bin (X,Y)=32]' 
--
-In this case, CFITSIO (1) copies and uncompresses the FITS file from
-the ftp site on the legacy machine, (2) moves to the 'EVENTS'
-extension, (3) calculates a new column called 'phacorr', (4) selects
-the rows in the table that have phacorr in the range 5 to 14, and
-finally (5) bins the remaining rows on the X and Y column coordinates,
-using a pixel size = 32 to create a 2D image.  All this processing is
-completely transparent to the application program, which simply sees
-the final 2-D image in the primary array of the opened file.
-\end{itemize}
-
-The full extended CFITSIO FITS file name can contain several different
-components depending on the context.  These components are described in
-the following sections:
--
-When creating a new file:
-   filetype://BaseFilename(templateName)
-
-When opening an existing primary array or image HDU:
-   filetype://BaseFilename(outName)[HDUlocation][ImageSection]
-
-When opening an existing table HDU:
-   filetype://BaseFilename(outName)[HDUlocation][colFilter][rowFilter][binSpec]
--
-The filetype, BaseFilename, outName, HDUlocation, and ImageSection
-components, if present, must be given in that order, but the colFilter,
-rowFilter, and binSpec specifiers may follow in any order.  Regardless
-of the order, however, the colFilter specifier, if present, will be
-processed first by CFITSIO, followed by the rowFilter specifier, and
-finally by the binSpec specifier.
-
-**A.  Filetype
-
-The type of file determines the medium on which the file is located
-(e.g., disk or network) and, hence, which internal device driver is used by
-CFITSIO to read and/or write the file.  Currently supported types are
--
-        file://  - file on local magnetic disk (default)
-        ftp://   - a readonly file accessed with the anonymous FTP protocol.
-                   It also supports  ftp://username:password@hostname/...
-                   for accessing password-protected ftp sites.
-        http://  - a readonly file accessed with the HTTP protocol.  It
-                   supports username:password just like the ftp driver.
-                   Proxy HTTP servers are supported using the http_proxy
-                   environment variable (see following note).
-      stream://  - special driver to read an input FITS file from the stdin
-                   stream, and/or write an output FITS file to the stdout
-		   stream.  This driver is fragile and has limited
-		   functionality (see the following note).
-      gsiftp://  - access files on a computational grid using the gridftp
-                   protocol in the Globus toolkit (see following note).
-        root://  - uses the CERN root protocol for writing as well as
-                   reading files over the network.
-        shmem:// - opens or creates a file which persists in the computer's
-                   shared memory.
-        mem://   - opens a temporary file in core memory.  The file 
-                   disappears when the program exits so this is mainly
-                   useful for test purposes when a permanent output file
-                   is not desired.
--
-If the filetype is not specified, then type file:// is assumed.
-The double slashes '//' are optional and may be omitted in most cases.
-
-***1.  Notes about HTTP proxy servers
-
-A proxy HTTP server may be used by defining the address (URL) and port 
-number of the proxy server with the http\_proxy environment variable.
-For example
--
-    setenv http_proxy http://heasarc.gsfc.nasa.gov:3128
--
-will cause CFITSIO to use port 3128 on the heasarc proxy server whenever
-reading a FITS file with HTTP.
-
-***2.  Notes about the stream filetype driver
-
-The stream driver can be used to efficiently read a FITS file from the stdin
-file stream or write a FITS to the stdout file stream.  However, because these
-input and output streams must be accessed sequentially, the FITS file reading or
-writing application must also read and write the file sequentially, at least
-within the tolerances described below.  
-
-CFITSIO supports 2 different methods for accessing FITS files on the stdin and
-stdout streams.  The original method, which is invoked by specifying a dash
-character, "-", as the name of the file when opening or creating it, works by
-storing a complete copy of the entire FITS file in memory.  In this case, when
-reading from stdin, CFITSIO will copy the entire stream into memory before doing
-any processing of the file.  Similarly, when writing to stdout, CFITSIO will
-create a copy of the entire FITS file in memory, before finally flushing it out
-to  the stdout stream when the FITS file is closed.  Buffering the entire FITS
-file in this way allows the application to randomly access any part of the FITS
-file, in any order, but it also requires that the user have sufficient available
-memory (or virtual memory) to store the entire file, which may not be possible
-in the case of very large files.  
-
-The newer stream filetype provides a more memory-efficient method of accessing
-FITS files on the stdin or stdout streams.  Instead of storing a copy of the
-entire FITS file in memory, CFITSIO only uses a set of internal  buffer which by
-default can store  40 FITS blocks, or about  100K bytes of the FITS file.  The
-application program must process the FITS file sequentially from beginning to
-end, within this 100K buffer.  Generally speaking the application  program must
-conform to the following restrictions:
-
-\begin{itemize}
-\item
-The program must finish reading or writing the header keywords 
-before reading or writing any data in the HDU.
-\item
-The HDU can contain at most about 1400 header keywords.  This is the
-maximum that can fit in the nominal 40 FITS block buffer.  In principle,
-this limit could be increased by recompiling CFITSIO with a larger
-buffer limit, which is set by the NIOBUF parameter in fitsio2.h.
-\item
-The program must read or write the data in a sequential manner from the 
-beginning to the end of the HDU.  Note that CFITSIO's internal 
-100K buffer allows a little latitude in meeting this requirement.
-\item
-The program cannot move back to a previous HDU in the FITS file.
-\item
-Reading or writing of variable length array columns in binary tables is not
-supported on streams, because this requires moving back and forth between the
-fixed-length portion of the binary table and the following heap area where the
-arrays are actually stored.
-\item
-Reading or writing of tile-compressed images is not supported on streams, 
-because the images are internally stored using variable length arrays.
-\end{itemize}
-
-***3.  Notes about the gsiftp filetype
-
-DEPENDENCIES: Globus toolkit (2.4.3 or higher) (GT) should be installed.
-There are two different ways to install GT:
-
-1) goto the globus toolkit web page www.globus.org and follow the
-   download and compilation instructions;
-   
-2) goto the Virtual Data Toolkit web page http://vdt.cs.wisc.edu/
-   and follow the instructions (STRONGLY SUGGESTED);
-
-Once a globus client has been installed in your system with a specific flavour
-it is possible to compile and install the CFITSIO libraries.
-Specific configuration flags must be used:
-
-1)  --with-gsiftp[[=PATH]] Enable Globus Toolkit gsiftp protocol support
-    PATH=GLOBUS\_LOCATION i.e. the location of your globus installation
-
-2)  --with-gsiftp-flavour[[=PATH] defines the specific Globus flavour
-        ex. gcc32
-
-Both the flags must be used and it is mandatory to set  both the PATH and the
-flavour.
-
-USAGE: To access files on a gridftp server it is necessary to use a gsiftp prefix:
-
-example: gsiftp://remote\_server\_fqhn/directory/filename
-
-The gridftp driver uses a local buffer on a temporary file the file is located
-in the /tmp directory. If you have special permissions on /tmp or you do not have a /tmp
-directory, it is possible to force another location setting the GSIFTP\_TMPFILE environment
-variable (ex. export GSIFTP\_TMPFILE=/your/location/yourtmpfile).
-
-Grid FTP supports multi channel transfer. By default a single channel transmission is
-available. However, it is possible to modify this behavior setting the GSIFTP\_STREAMS
-environment variable (ex. export GSIFTP\_STREAMS=8).
-
-***4.  Notes about the root filetype
-
-The original rootd server can be obtained from:
-\verb-ftp://root.cern.ch/root/rootd.tar.gz-
-but, for it to work correctly with CFITSIO one has to use a modified
-version which supports a command to return the length of the file. 
-This modified version is available in rootd subdirectory
-in the CFITSIO ftp area at
--
-      ftp://legacy.gsfc.nasa.gov/software/fitsio/c/root/rootd.tar.gz.  
--
-
-This small server is started either by inetd when a client requests a
-connection to a rootd server or by hand (i.e. from the command line).
-The rootd server works with the ROOT TNetFile class. It allows remote
-access to ROOT database files in either read or write mode. By default
-TNetFile assumes port 432 (which requires rootd to be started as root).
-To run rootd via inetd add the following line to /etc/services:
--                                                                          
-  rootd     432/tcp                                                    
--                                                                    
-and to /etc/inetd.conf, add the following line: 
--
-  rootd stream tcp nowait root /user/rdm/root/bin/rootd rootd -i       
--                                                                    
-Force inetd to reread its conf file with "kill -HUP <pid inetd>".    
-You can also start rootd by hand running directly under your private 
-account (no root system privileges needed). For example to start     
-rootd listening on port 5151 just type:   \verb+rootd -p 5151+  
-Notice: no \& is needed. Rootd will go into background by itself.       
--
-  Rootd arguments:                                                     
-    -i                says we were started by inetd                    
-    -p port#          specifies a different port to listen on          
-    -d level          level of debug info written to syslog            
-                      0 = no debug (default)                           
-                      1 = minimum                                      
-                      2 = medium                                       
-                      3 = maximum                                      
--
-Rootd can also be configured for anonymous usage (like anonymous ftp).
-To setup rootd to accept anonymous logins do the following (while being
-logged in as root):                                  
--
-   - Add the following line to /etc/passwd:                             
-                                                                     
-     rootd:*:71:72:Anonymous rootd:/var/spool/rootd:/bin/false          
-                                                                     
-     where you may modify the uid, gid (71, 72) and the home directory  
-     to suite your system.                                              
-                                                                     
-   - Add the following line to /etc/group:                              
-                                                                     
-     rootd:*:72:rootd                                                   
-                                                                     
-     where the gid must match the gid in /etc/passwd.                   
-                                                                     
-   - Create the directories:                                            
-                                                                     
-     mkdir /var/spool/rootd                                             
-     mkdir /var/spool/rootd/tmp                                         
-     chmod 777 /var/spool/rootd/tmp                                     
-                                                                     
-     Where /var/spool/rootd must match the rootd home directory as      
-     specified in the rootd /etc/passwd entry.                          
-                                                                     
-   - To make writeable directories for anonymous do, for example:       
-                                                                     
-     mkdir /var/spool/rootd/pub                                         
-     chown rootd:rootd /var/spool/rootd/pub                             
--
-That's all.  Several additional remarks:  you can login to an anonymous
-server either with the names "anonymous" or "rootd".  The password should
-be of type user@host.do.main. Only the @ is enforced for the time
-being.  In anonymous mode the top of the file tree is set to the rootd
-home directory, therefore only files below the home directory can be
-accessed.  Anonymous mode only works when the server is started via
-inetd.
-
-***5.  Notes about the shmem filetype:
-
-Shared memory files are currently supported on most Unix platforms,
-where the shared memory segments are managed by the operating system
-kernel and `live' independently of processes. They are not deleted (by
-default) when the process which created them terminates, although they
-will disappear if the system is rebooted.  Applications can create
-shared memory files in CFITSIO by calling:
--
-   fit_create_file(&fitsfileptr, "shmem://h2", &status);
--
-where the root `file' names are currently restricted to be 'h0', 'h1',
-'h2', 'h3', etc., up to a maximum number defined by the the value of
-SHARED\_MAXSEG (equal to 16 by default).  This is a prototype
-implementation of the shared memory interface and a more robust
-interface, which will have fewer restrictions on the number of files
-and on their names, may be developed in the future.
-
-When opening an already existing FITS file in shared memory one calls
-the usual CFITSIO routine:
--
-   fits_open_file(&fitsfileptr, "shmem://h7", mode, &status)
--
-The file mode can be READWRITE or READONLY just as with disk files.
-More than one process can operate on READONLY mode files at the same
-time.  CFITSIO supports proper file locking (both in READONLY and
-READWRITE modes), so calls to fits\_open\_file may be locked out until
-another other process closes the file.
-
-When an application is finished accessing a FITS file in a shared
-memory segment, it may close it  (and the file will remain in the
-system) with fits\_close\_file, or delete it with fits\_delete\_file.
-Physical deletion is postponed until the last process calls
-ffclos/ffdelt.  fits\_delete\_file tries to obtain a READWRITE lock on
-the file to be deleted, thus it can be blocked if the object was not
-opened in READWRITE mode.
-
-A shared memory management utility program called `smem', is included
-with the CFITSIO distribution.  It can be built by typing `make smem';
-then type `smem -h' to get a list of valid options.  Executing smem
-without any options causes it to list all the shared memory segments
-currently residing in the system and managed by the shared memory
-driver. To get a list of all the shared memory objects, run the system
-utility program `ipcs  [-a]'.
-
-**B.  Base Filename
-
-The base filename is the name of the file optionally including the
-director/subdirectory path, and in the case of `ftp', `http', and `root'
-filetypes, the machine identifier.  Examples:
--
-    myfile.fits
-    !data.fits
-    /data/myfile.fits
-    fits.gsfc.nasa.gov/ftp/sampledata/myfile.fits.gz
--
-
-When creating a new output file on magnetic disk (of type file://) if
-the base filename begins with an exclamation point (!) then any
-existing file with that same basename will be deleted prior to creating
-the new FITS file.  Otherwise if the file to be created already exists,
-then CFITSIO will return an error and will not overwrite the existing
-file.  Note  that the exclamation point,  '!', is a special UNIX character,
-so if it is used  on the command line rather than entered at a task
-prompt, it must be  preceded by a backslash to force the UNIX
-shell to pass it verbatim to the application program.
-
-If the output disk file name ends with the suffix '.gz', then CFITSIO
-will compress the file using the gzip compression algorithm before
-writing it to disk.  This can reduce the amount of disk space used by
-the file.  Note that this feature requires that the uncompressed file
-be constructed in memory before it is compressed and written to disk,
-so it can fail if there is insufficient available memory.
-
-An input FITS file may be compressed with the gzip or Unix compress
-algorithms, in which case CFITSIO will uncompress the file on the fly
-into a temporary file (in memory or on disk).  Compressed files may
-only be opened with read-only permission.  When specifying the name of
-a compressed FITS file it is not necessary to append the file suffix
-(e.g., `.gz' or `.Z').  If CFITSIO cannot find the input file name
-without the suffix, then it will automatically search for a compressed
-file with the same root name.  In the case of reading ftp and http type
-files, CFITSIO generally looks for a compressed version of the file
-first, before trying to open the uncompressed file.  By default,
-CFITSIO copies (and uncompressed if necessary) the ftp or http FITS
-file into memory on the local machine before opening it.  This will
-fail if the local machine does not have enough memory to hold the whole
-FITS file, so in this case, the output filename specifier (see the next
-section) can be used to further control how CFITSIO reads ftp and http
-files.
-
-If the input file is an IRAF image file (*.imh file) then CFITSIO will
-automatically convert it on the fly into a virtual FITS image before it
-is opened by the application program.  IRAF images can only be opened
-with READONLY file access.
-
-Similarly, if the input file is a raw binary data array, then CFITSIO
-will convert it on the fly into a virtual FITS image with the basic set
-of required header keywords before it is opened by the application
-program (with READONLY access).  In this case the data type and
-dimensions of the image must be specified in square brackets following
-the filename (e.g. rawfile.dat[ib512,512]). The first character (case
-insensitive) defines the datatype of the array:
--
-     b         8-bit unsigned byte
-     i        16-bit signed integer
-     u        16-bit unsigned integer
-     j        32-bit signed integer
-     r or f   32-bit floating point
-     d        64-bit floating point
--
-An optional second character specifies the byte order of the array
-values: b or B indicates big endian (as in FITS files and the native
-format of SUN UNIX workstations and Mac PCs) and l or L indicates
-little endian (native format of DEC OSF workstations and IBM PCs).  If
-this character is omitted then the array is assumed to have the native
-byte order of the local machine.  These datatype characters are then
-followed by a series of one or more integer values separated by commas
-which define the size of each dimension of the raw array.  Arrays with
-up to 5 dimensions are currently supported.  Finally, a byte offset to
-the position of the first pixel in the data file may be specified by
-separating it with a ':' from the last dimension value.  If omitted, it
-is assumed that the offset = 0.  This parameter may be used to skip
-over any header information in the file that precedes the binary data.
-Further examples:
--
-  raw.dat[b10000]           1-dimensional 10000 pixel byte array
-  raw.dat[rb400,400,12]     3-dimensional floating point big-endian array
-  img.fits[ib512,512:2880]  reads the 512 x 512 short integer array in 
-                            a FITS file, skipping over the 2880 byte header
--
-
-One special case of input file is where the filename = `-' (a dash or
-minus sign) or 'stdin' or 'stdout', which signifies that the input file
-is to be read from the stdin stream, or written to the stdout stream if
-a new output file is being created.  In the case of reading from stdin,
-CFITSIO first copies the whole stream into a temporary FITS file (in
-memory or on disk), and subsequent reading of the FITS file occurs in
-this copy.  When writing to stdout, CFITSIO first constructs the whole
-file in memory (since random access is required), then flushes it out
-to the stdout stream when the file is closed.   In addition, if the
-output filename = '-.gz' or 'stdout.gz' then it will be gzip compressed
-before being written to stdout.
-
-This ability to read and write on the stdin and stdout steams allows
-FITS files to be piped between tasks in memory rather than having to
-create temporary intermediate FITS files on disk.  For example if task1
-creates an output FITS file, and task2 reads an input FITS file, the
-FITS file may be piped between the 2 tasks by specifying
--
-   task1 - | task2 - 
--
-where the vertical bar is the Unix piping symbol.  This assumes that the 2
-tasks read the name of the FITS file off of the command line.
-
-**C.  Output File Name when Opening an Existing File
-
-An optional output filename may be specified in parentheses immediately
-following the base file name to be opened.  This is mainly useful in
-those cases where CFITSIO creates a temporary copy of the input FITS
-file before it is opened and passed to the application program.  This
-happens by default when opening a network FTP or HTTP-type file, when
-reading a compressed FITS file on a local disk, when reading from the
-stdin stream, or when a column filter, row filter, or binning specifier
-is included as part of the input file specification.  By default this
-temporary file is created in memory.  If there is not enough memory to
-create the file copy, then CFITSIO will exit with an error.   In these
-cases one can force a permanent file to be created on disk, instead of
-a temporary file in memory, by supplying the name in parentheses
-immediately following the base file name.  The output filename can
-include the '!' clobber flag.
-
-Thus, if the input filename to CFITSIO is:
-\verb+file1.fits.gz(file2.fits)+
-then CFITSIO will uncompress `file1.fits.gz' into the local disk file
-`file2.fits' before opening it.  CFITSIO does not automatically delete
-the output file, so it will still exist after the application program
-exits.
-
-In some cases, several different temporary FITS files will be created
-in sequence, for instance, if one opens a remote file using FTP, then
-filters rows in a binary table extension, then create an image by
-binning a pair of columns.  In this case, the remote file will be
-copied to a temporary local file, then a second temporary file will be
-created containing the filtered rows of the table, and finally a third
-temporary file containing the binned image will be created.  In cases
-like this where multiple files are created, the outfile specifier will
-be interpreted the name of the final file as described below, in descending
-priority:
-
-\begin{itemize}
-\item
-as the name of the final image file if an image within a single binary
-table cell is opened or if an image is created by binning a table column.
-\item
-as the name of the file containing the filtered table if a column filter
-and/or a row filter are specified.
-\item
-as the name of the local copy of the remote FTP or HTTP file.
-\item
-as the name of the uncompressed version of the FITS file, if a
-compressed FITS file on local disk has been opened.
-\item
-otherwise, the output filename is ignored.
-\end{itemize}
-
-
-The output file specifier is useful when reading FTP or HTTP-type
-FITS files since it can be used to create a local disk copy of the file
-that can be reused in the future.  If the output file name = `*' then a
-local file with the same name as the network file will be created.
-Note that CFITSIO will behave differently depending on whether the
-remote file is compressed or not as shown by the following examples:
-\begin{itemize}
-\item
-`ftp://remote.machine/tmp/myfile.fits.gz(*)' - the remote compressed
-file is copied to the local compressed file `myfile.fits.gz', which
-is then uncompressed in local memory before being opened and passed
-to the application program.
-
-\item
-`ftp://remote.machine/tmp/myfile.fits.gz(myfile.fits)' - the remote
-compressed file is copied and uncompressed into the local file
-`myfile.fits'.  This example requires less local memory than the
-previous example since the file is uncompressed on disk instead of
-in memory.
-
-\item
-`ftp://remote.machine/tmp/myfile.fits(myfile.fits.gz)' - this will
-usually produce an error since CFITSIO itself cannot compress files.
-\end{itemize}
-
-The exact behavior of CFITSIO in the latter case depends on the type of
-ftp server running on the remote machine and how it is configured.  In
-some cases, if the file `myfile.fits.gz' exists on the remote machine,
-then the server will copy it to the local machine.  In other cases the
-ftp server will automatically create and transmit a compressed version
-of the file if only the uncompressed version exists.  This can get
-rather confusing, so users should use a certain amount of caution when
-using the output file specifier with FTP or HTTP file types, to make
-sure they get the behavior that they expect.
-
-**D.  Template File Name when Creating a New File
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described below.
-
-**E.  Image Tile-Compression Specification
-
-When specifying the name of the output FITS file to be created, the
-user can indicate that images should be written in tile-compressed
-format (see section 5.5, ``Primary Array or IMAGE Extension I/O
-Routines'') by enclosing the compression parameters in square brackets
-following the root disk file name.  Here are some examples of the
-syntax for specifying tile-compressed output images:
--
-    myfile.fit[compress]    - use Rice algorithm and default tile size
-
-    myfile.fit[compress GZIP] - use the specified compression algorithm;
-    myfile.fit[compress Rice]     only the first letter of the algorithm 
-    myfile.fit[compress PLIO]     name is required.
-
-    myfile.fit[compress Rice 100,100]   - use 100 x 100 pixel tile size
-    myfile.fit[compress Rice 100,100;2] - as above, and use noisebits = 2
--
-
-**F.  HDU Location Specification
-
-The optional HDU location specifier defines which HDU (Header-Data
-Unit, also known as an `extension') within the FITS file to initially
-open.  It must immediately follow the base file name (or the output
-file name if present).  If it is not specified then the first HDU (the
-primary array) is opened.  The HDU location specifier is required if
-the colFilter, rowFilter, or binSpec specifiers are present, because
-the primary array is not a valid HDU for these operations. The HDU may
-be specified either by absolute position number, starting with 0 for
-the primary array, or by reference to the HDU name, and optionally, the
-version number and the HDU type of the desired extension.  The location
-of an image within a single cell of a binary table may also be 
-specified, as described below.
-
-The absolute position of the extension is specified either by enclosed
-the number in square brackets (e.g., `[1]' = the first extension
-following the primary array) or by preceded the number with a plus sign
-(`+1').  To specify the HDU by name, give the name of the desired HDU
-(the value of the EXTNAME or HDUNAME keyword) and optionally the
-extension version number (value of the EXTVER keyword) and the
-extension type (value of the XTENSION keyword: IMAGE, ASCII or TABLE,
-or BINTABLE), separated by commas and all enclosed in square brackets.
-If the value of EXTVER and XTENSION are not specified, then the first
-extension with the correct value of EXTNAME is opened. The extension
-name and type are not case sensitive, and the extension type may be
-abbreviated to a single letter (e.g., I = IMAGE extension or primary
-array, A or T = ASCII table extension, and B = binary table BINTABLE
-extension).   If the HDU location specifier is equal to `[PRIMARY]' or
-`[P]', then the primary array (the first HDU) will be opened.
-
-FITS images are most commonly stored in the primary array or an image
-extension, but images can also be stored as a vector in a single cell
-of a binary table (i.e. each row of the vector column contains a
-different image).  Such an image can be opened with CFITSIO by
-specifying the desired column  name and the row number after the binary
-table HDU specifier as shown in the following examples. The column name
-is separated from the HDU specifier by a semicolon and the row number
-is enclosed in parentheses.  In this case CFITSIO copies the image from
-the table cell into a temporary primary array before it is opened.  The
-application program then just sees the image in the primary array,
-without any extensions.  The particular row to be opened may be
-specified either by giving an absolute integer row number (starting
-with 1 for the first row), or by specifying a boolean expression that
-evaluates to TRUE for the desired row.  The first row that satisfies
-the expression will be used.  The row selection expression has the same
-syntax as described in the Row Filter Specifier section, below.
-
- Examples:
--
-   myfile.fits[3] - open the 3rd HDU following the primary array
-   myfile.fits+3  - same as above, but using the FTOOLS-style notation  
-   myfile.fits[EVENTS] - open the extension that has EXTNAME = 'EVENTS'
-   myfile.fits[EVENTS, 2]  - same as above, but also requires EXTVER = 2
-   myfile.fits[events,2,b] - same, but also requires XTENSION = 'BINTABLE'
-   myfile.fits[3; images(17)] - opens the image in row 17 of the 'images'
-                                column in the 3rd extension of the file.
-   myfile.fits[3; images(exposure > 100)] - as above, but opens the image
-                   in the first row that has an 'exposure' column value
-                   greater than 100.

-
-**G.  Image Section
-
-A virtual file containing a rectangular subsection of an image can be
-extracted and opened by specifying the range of pixels (start:end)
-along each axis to be extracted from the original image.  One can also
-specify an optional pixel increment (start:end:step) for each axis of
-the input image.  A pixel step = 1 will be assumed if it is not
-specified.  If the start pixel is larger then the end pixel, then the
-image will be flipped (producing a mirror image) along that dimension.
-An asterisk, '*', may be used to specify the entire range of an axis,
-and '-*' will flip the entire axis. The input image can be in the
-primary array, in an image extension, or contained in a vector cell of
-a binary table. In the later 2 cases the extension name or number must
-be specified before the image section specifier.
-
- Examples:
--
-  myfile.fits[1:512:2, 2:512:2] -  open a 256x256 pixel image
-              consisting of the odd numbered columns (1st axis) and 
-              the even numbered rows (2nd axis) of the image in the 
-              primary array of the file.
-
-  myfile.fits[*, 512:256] - open an image consisting of all the columns
-              in the input image, but only rows 256 through 512.  
-              The image will be flipped along the 2nd axis since
-              the starting pixel is greater than the ending pixel.
-
-  myfile.fits[*:2, 512:256:2] - same as above but keeping only
-              every other row and column in the input image.
-
-  myfile.fits[-*, *] - copy the entire image, flipping it along
-              the first axis.
-
-  myfile.fits[3][1:256,1:256] - opens a subsection of the image that
-              is in the 3rd extension of the file.
-
-  myfile.fits[4; images(12)][1:10,1:10] - open an image consisting
-	      of the first 10 pixels in both dimensions. The original
-	      image resides in the 12th row of the 'images' vector
-	      column in the table in the 4th extension of the file.
--
-
-When CFITSIO opens an image section it first creates a temporary file
-containing the image section plus a copy of any other HDUs in the
-file.  This temporary file is then opened by the application program,
-so it is not possible to write to or modify the input file when
-specifying an image section.  Note that CFITSIO automatically updates
-the world coordinate system keywords in the header of the image
-section, if they exist, so that the coordinate associated with each
-pixel in the image section will be computed correctly.
-
-**H.  Image Transform Filters
-
-CFITSIO can apply a user-specified mathematical function to the value
-of every pixel in a FITS image, thus creating a new virtual image
-in computer memory that is then opened and read by the application
-program.  The original FITS image is not modified by this process.
-
-The image transformation specifier is appended to the input
-FITS file name and is enclosed in square brackets.  It begins with the 
-letters 'PIX' to distinguish it from other types of FITS file filters
-that are recognized by CFITSIO.  The image transforming function may
-use any of the mathematical operators listed in the following 
-'Row Filtering Specification' section of this document.
-Some examples of  image transform filters are:
--
- [pix X * 2.0]               - multiply each pixel by 2.0
- [pix sqrt(X)]               - take the square root of each pixel
- [pix X + #ZEROPT            - add the value of the ZEROPT keyword
- [pix X>0 ? log10(X) : -99.] - if the pixel value is greater
-                               than 0, compute the base 10 log,
-                               else set the pixel = -99.
--
-Use the letter 'X' in the expression to represent the current pixel value
-in the image.  The expression is evaluated
-independently for each pixel in the image and may be a function of 1) the
-original pixel value, 2) the value of other pixels in the image at
-a given relative offset from the position of the pixel that is being
-evaluated, and 3) the value of 
-any header keywords.  Header keyword values are represented
-by the name of the keyword preceded by the '\#' sign.
-
-
-To access the the value of adjacent pixels in the image, 
-specify the (1-D) offset from the current pixel in curly brackets.  
-For example
--
- [pix  (x{-1} + x + x{+1}) / 3] 
--
-will replace each pixel value with the running mean of the values of that
-pixel and it's 2 neighboring pixels.  Note that in this notation the image
-is treated as a 1-D array, where each row of the image (or higher dimensional
-cube) is appended one after another in one long array of pixels.  
-It is possible to refer to pixels
-in the rows above or below the current pixel by using the value of the
-NAXIS1 header keyword.  For example
--
- [pix (x{-#NAXIS1} + x + x{#NAXIS1}) / 3]
--
-will compute the mean of each image pixel and the pixels immediately
-above and below it in the adjacent rows of the image.  
-The following more complex example
-creates a smoothed virtual image where each pixel 
-is a 3 x 3 boxcar average of the input image pixels: 
--
-  [pix (X + X{-1} + X{+1} 
-      + X{-#NAXIS1} + X{-#NAXIS1 - 1} + X{-#NAXIS1 + 1}
-      + X{#NAXIS1} + X{#NAXIS1 - 1} + X{#NAXIS1 + 1}) / 9.]
--
-If the pixel offset
-extends beyond the first or last pixel in the image, the function will
-evaluate to undefined, or NULL.
-
-For  complex  or commonly used image filtering operations,  
-one  can  write the expression into an external text  file and 
-then import it  into the  
-filter using  the syntax '[pix @filename.txt]'.   The mathematical
-expression can
-extend over multiple lines of text in the  file.   
-Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-By default, the datatype of the resulting image will be the same as
-the original image, but one may force a different datatype by appended
-a code letter to the 'pix' keyword:
--
-      pixb  -  8-bit byte    image with BITPIX =   8
-      pixi  - 16-bit integer image with BITPIX =  16
-      pixj  - 32-bit integer image with BITPIX =  32
-      pixr  - 32-bit float   image with BITPIX = -32
-      pixd  - 64-bit float   image with BITPIX = -64
--
-Also by default, any other HDUs in the input file will be copied without
-change to the 
-output virtual FITS file, but one may discard the other HDUs by adding 
-the number '1' to the 'pix' keyword (and following any optional datatype code
-letter).  For example:
--
-     myfile.fits[3][pixr1  sqrt(X)]
-- 
-will create a virtual FITS file containing only a primary array image
-with 32-bit floating point pixels that have a value equal to the square 
-root of the pixels in the image that is in the 3rd extension 
-of the 'myfile.fits' file.
-
-
-
-**I.  Column and Keyword Filtering Specification
-
-The optional column/keyword filtering specifier is used to modify the
-column structure and/or the header keywords in the HDU that was
-selected with the previous HDU location specifier. This filtering
-specifier must be enclosed in square brackets and can be distinguished
-from a general row filter specifier (described below) by the fact that
-it begins with the string 'col ' and is not immediately followed by an
-equals sign.  The original file is not changed by this filtering
-operation, and instead the modifications are made on a copy of the
-input FITS file (usually in memory), which also contains a copy of all
-the other HDUs in the file.  This temporary file is passed to the
-application program and will persist only until the file is closed or
-until the program exits, unless the outfile specifier (see above) is
-also supplied.
-
-The column/keyword filter can be used to perform the following
-operations.  More than one operation may be specified by separating
-them with commas or semi-colons.
-
-\begin{itemize}
-
-\item
-Copy only a specified list of columns columns to the filtered input file.
-The list of column name should be separated by semi-colons.  Wild card
-characters may be used in the column names to match multiple columns.
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table 
-except the explicitly deleted columns will appear in the filtered
-table (i.e., there is no need to explicitly list the columns to
-be included if any columns are being deleted).
-
-\item
-Delete a column or keyword by listing the name preceded by a minus
-sign or an exclamation mark (!), e.g., '-TIME' will delete the TIME
-column if it exists, otherwise the TIME keyword.  An error is returned
-if neither a column nor keyword with this name exists.  Note  that the
-exclamation point,  '!', is a special UNIX character, so if it is used
-on the command line rather than entered at a task prompt, it must be
-preceded by a backslash to force the UNIX shell to ignore it.
-
-\item
-Rename an existing column or keyword with the syntax 'NewName ==
-OldName'.  An error is returned if neither a column nor keyword with
-this name exists.
-
-\item
-Append a new column or keyword to the table.  To create a column,
-give the new name, optionally followed by the datatype in parentheses,
-followed by a single equals sign and an  expression to be used to
-compute the value (e.g., 'newcol(1J) = 0' will create a new 32-bit
-integer column called 'newcol' filled with zeros).  The datatype is
-specified using the same syntax that is allowed for the value of the
-FITS TFORMn keyword (e.g., 'I', 'J', 'E', 'D', etc. for binary tables,
-and 'I8', F12.3', 'E20.12', etc. for ASCII tables).  If the datatype is
-not specified then an appropriate datatype will be chosen depending on
-the form of the expression (may be a character string, logical, bit, long
-integer, or double column). An appropriate vector count (in the case
-of binary tables) will also be added if not explicitly specified.
-
-When creating a new keyword, the keyword name must be preceded by a 
-pound sign '\#', and the expression must evaluate to a scalar
-(i.e., cannot have a column name in the expression).  The comment
-string for the keyword may be specified in parentheses immediately
-following the keyword name (instead of supplying a datatype as in
-the case of creating a new column).  If the keyword name ends with a
-pound sign '\#', then cfitsio will substitute the number of the 
-most recently referenced column for the \# character .  
-This is especially useful when writing
-a column-related keyword like TUNITn for a newly created column,
-as shown in the following examples.
-
-\item
-Recompute (overwrite) the values in an existing column or keyword by
-giving the name followed by an equals sign and an arithmetic
-expression.
-\end{itemize}
-
-The expression that is used when appending or recomputing columns or
-keywords can be arbitrarily complex and may be a function of other
-header keyword values and other columns (in the same row).  The full
-syntax and available functions for the expression are described below
-in the row filter specification section.
-
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table 
-except the explicitly deleted columns will appear in the filtered
-table.  If no columns to be deleted are specified, then only the
-columns that are explicitly listed will be included in the filtered
-output table.  To include all the columns, add the '*' wildcard
-specifier at the end of the list, as shown in the examples.
-
-For  complex  or commonly used operations,  one  can also  place the
-operations into an external text  file and import it  into the  column
-filter using  the syntax '[col @filename.txt]'.   The operations can
-extend over multiple lines of the  file, but multiple operations must
-still be separated by semicolons.   Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-Examples:
--
-   [col Time; rate]              - only the Time and rate columns will
-                                   appear in the filtered input file.
-
-   [col Time, *raw]              - include the Time column and any other
-                                   columns whose name ends with 'raw'.
-
-   [col -TIME; Good == STATUS]   - deletes the TIME column and
-                                   renames the status column to 'Good'
-
-   [col PI=PHA * 1.1 + 0.2; #TUNIT#(column units) = 'counts';*]
-                                 - creates new PI column from PHA values
-                                   and also writes the TUNITn keyword
-                                   for the new column.  The final '*'
-                                   expression means preserve all the
-                                   columns in the input table in the
-                                   virtual output table;  without the '*'
-                                   the output table would only contain
-                                   the single 'PI' column.
-
-   [col rate = rate/exposure; TUNIT#(&) = 'counts/s';*]
-                                 - recomputes the rate column by dividing
-                                   it by the EXPOSURE keyword value. This
-                                   also modifies the value of the TUNITn
-                                   keyword for this column. The use of the
-                                   '&' character for the keyword comment
-                                   string means preserve the existing
-                                   comment string for that keyword. The
-                                   final '*' preserves all the columns
-                                   in the input table in the virtual
-                                   output table.

-**J.  Row Filtering Specification
-
-    When entering the name of a FITS table that is to be opened by a
-    program, an optional row filter may be specified to select a subset
-    of the rows in the table.  A temporary new FITS file is created on
-    the fly which contains only those rows for which the row filter
-    expression evaluates to true.  (The primary array and any other
-    extensions in the input file are also copied to the temporary
-    file).  The original FITS file is closed and the new virtual file
-    is opened by the application program.  The row filter expression is
-    enclosed in square brackets following the file name and extension
-    name (e.g., 'file.fits[events][GRADE==50]'  selects only those rows
-    where the GRADE column value equals 50).   When dealing with tables
-    where each row has an associated time and/or 2D spatial position,
-    the row filter expression can also be used to select rows based on
-    the times in a Good Time Intervals (GTI) extension, or on spatial
-    position as given in a SAO-style region file.
-
-***1.  General Syntax
-
-    The row filtering  expression can be an arbitrarily  complex series
-    of operations performed  on constants,  keyword values,  and column
-    data taken from the specified FITS TABLE extension.  The expression
-    must evaluate to a boolean  value for each row  of the table, where
-    a value of FALSE means that the row will be excluded.
-
-    For complex or commonly  used filters, one can place the expression
-    into a text file and import it into the row filter using the syntax
-    '[@filename.txt]'.  The expression can be  arbitrarily complex and
-    extend over multiple lines of the file.  Any lines in the external
-    text file that begin with 2 slash characters ('//') will be ignored
-    and may be used to add comments into the file.
-
-    Keyword and   column data  are referenced by   name.  Any  string of
-    characters not surrounded by    quotes (ie, a constant  string)   or
-    followed by   an open parentheses (ie,   a  function name)   will be
-    initially interpreted   as a column  name and  its contents for the
-    current row inserted into the expression.  If no such column exists,
-    a keyword of that  name will be searched for  and its value used, if
-    found.  To force the  name to be  interpreted as a keyword (in case
-    there is both a column and keyword with the  same name), precede the
-    keyword name with a single pound sign, '\#', as in '\#NAXIS2'.  Due to
-    the generalities of FITS column and  keyword names, if the column or
-    keyword name  contains a space or a  character which might appear as
-    an arithmetic  term then enclose  the  name in '\$'  characters as in
-    \$MAX PHA\$ or \#\$MAX-PHA\$.  Names are case insensitive.
-
-    To access a table entry in a row other  than the current one, follow
-    the  column's name  with  a row  offset  within  curly  braces.  For
-    example, 'PHA\{-3\}' will evaluate to the value  of column PHA, 3 rows
-    above  the  row currently  being processed.   One  cannot specify an
-    absolute row number, only a relative offset.  Rows that fall outside
-    the table will be treated as undefined, or NULLs.
-
-    Boolean   operators can be  used in  the expression  in either their
-    Fortran or C forms.  The following boolean operators are available:
--
-    "equal"         .eq. .EQ. ==  "not equal"          .ne.  .NE.  !=
-    "less than"     .lt. .LT. <   "less than/equal"    .le.  .LE.  <= =<
-    "greater than"  .gt. .GT. >   "greater than/equal" .ge.  .GE.  >= =>
-    "or"            .or. .OR. ||  "and"                .and. .AND. &&
-    "negation"     .not. .NOT. !  "approx. equal(1e-7)"  ~
--
-
-Note  that the exclamation
-point,  '!', is a special UNIX character, so if it is used  on the
-command line rather than entered at a task prompt, it must be  preceded
-by a backslash to force the UNIX shell to ignore it.
-
-    The expression may  also include arithmetic operators and functions.
-    Trigonometric  functions use  radians,  not degrees.  The  following
-    arithmetic  operators and  functions  can be  used in the expression
-    (function names are case insensitive). A null value will be returned
-    in case of illegal operations such as divide by zero, sqrt(negative)
-    log(negative), log10(negative), arccos(.gt. 1), arcsin(.gt. 1).

-    "multiplication"     *          "division"             /

--
-Three different random number functions are provided:  random(), with no
-arguments, produces a uniform random deviate between 0 and 1; randomn(),
-also with no arguments, produces a normal (Gaussian) random deviate  with
-zero mean and unit standard deviation; randomp(x) produces a Poisson random
-deviate whose expected number of counts is X.  X may be any positive real
-number of expected counts, including fractional values, but the return value
-is an integer.
-
-When the random functions are used in a vector expression, by default
-the same random value will be used when evaluating each element of the vector.
-If different random numbers are desired, then the name of a vector 
-column should be supplied as the single argument to the random 
-function (e.g., "flux + 0.1 * random(flux)", where "flux' is the
-name of a vector column).  This will create a vector of 
-random numbers that will be used in sequence when evaluating each 
-element of the vector expression.
-
-    An alternate syntax for the min and max functions  has only a single
-    argument which  should be  a  vector value (see  below).  The result
-    will be the minimum/maximum element contained within the vector.
-
-    The accum(x) function forms the cumulative sum of x, element by element.
-    Vector columns are supported simply by performing the summation process
-    through all the values.  Null values are treated as 0.  The seqdiff(x) 
-    function forms the sequential difference of x, element by element.  
-    The first value of seqdiff is the first value of x.  A single null 
-    value in x causes a pair of nulls in the output.  The seqdiff and 
-    accum functions are functional inverses, i.e., seqdiff(accum(x)) == x
-    as long as no null values are present.
-    
-In the if-then-else expression, "b?x:y", b is an explicit boolean
-value or expression.  There is no automatic type conversion from
-numeric to boolean values, so one needs to use "iVal!=0" instead of
-merely "iVal" as the boolean argument. x and y can be any scalar data
-type (including string).
-
-    The angsep function computes the angular separation in degrees 
-    between 2 celestial positions, where the first 2 parameters
-    give the RA-like and Dec-like coordinates (in decimal degrees)
-    of the first position, and the 3rd and 4th parameters give the
-    coordinates of the second position.
-
-The substring function strmid(S,P,N) extracts a substring from S, 
-starting at string position P, with a substring length N.  The first 
-character position in S is labeled as 1. If P is 0, or refers to a 
-position beyond the end of S, then the extracted substring will be 
-NULL.   S, P, and N may be functions of other columns.
-
-The string search function strstr(S,R) searches for the first occurrence 
-of the substring R in S.  The result is an integer, indicating the 
-character position of the first match (where 1 is the first character 
-position of S).  If no match is found, then strstr() returns a NULL
-value.
-    
-    The  following  type  casting  operators  are  available,  where the
-    enclosing parentheses are required and taken  from  the  C  language
-    usage. Also, the integer to real casts values to double precision:
--
-                "real to integer"    (int) x     (INT) x
-                "integer to real"    (float) i   (FLOAT) i
--
-
-    In addition, several constants are built in  for  use  in  numerical
-    expressions:
-
--
-        #pi              3.1415...      #e             2.7182...
-        #deg             #pi/180        #row           current row number
-        #null         undefined value   #snull         undefined string
--
-
-    A  string constant must  be enclosed  in quotes  as in  'Crab'.  The
-    "null" constants  are useful for conditionally  setting table values
-    to a NULL, or undefined, value (eg., "col1==-99 ? \#NULL : col1").
-
-    There is also a function for testing if  two  values  are  close  to
-    each  other,  i.e.,  if  they are "near" each other to within a user
-    specified tolerance. The  arguments,  value\_1  and  value\_2  can  be
-    integer  or  real  and  represent  the two values who's proximity is
-    being tested to be within the specified tolerance, also  an  integer
-    or real:
--
-                    near(value_1, value_2, tolerance)
--
-    When  a  NULL, or undefined, value is encountered in the FITS table,
-    the expression will evaluate to NULL unless the undefined  value  is
-    not   actually   required  for  evaluation,  e.g. "TRUE  .or.  NULL" 
-    evaluates to TRUE. The  following  two  functions  allow  some  NULL
-    detection  and  handling:
--
-         "a null value?"              ISNULL(x)
-         "define a value for null"    DEFNULL(x,y)
--
-    The former
-    returns a boolean value of TRUE if the  argument  x  is  NULL.   The
-    later  "defines"  a  value  to  be  substituted  for NULL values; it
-    returns the value of x if x is not NULL, otherwise  it  returns  the
-    value of y.
-    
-***2.  Bit Masks
-
-    Bit  masks can be used to select out rows from bit columns (TFORMn =
-    \#X) in FITS files. To represent the mask,  binary,  octal,  and  hex
-    formats are allowed:
-
--
-                 binary:   b0110xx1010000101xxxx0001
-                 octal:    o720x1 -> (b111010000xxx001)
-                 hex:      h0FxD  -> (b00001111xxxx1101)
--
-   
-    In  all  the  representations, an x or X is allowed in the mask as a
-    wild card. Note that the x represents a  different  number  of  wild
-    card  bits  in  each  representation.  All  representations are case
-    insensitive.
-    
-    To construct the boolean expression using the mask  as  the  boolean
-    equal  operator  described above on a bit table column. For example,
-    if you had a 7 bit column named flags in a  FITS  table  and  wanted
-    all  rows  having  the bit pattern 0010011, the selection expression
-    would be:
-
--
-                            flags == b0010011
-    or
-                            flags .eq. b10011
--
-
-    It is also possible to test if a range of bits is  less  than,  less
-    than  equal,  greater  than  and  greater than equal to a particular
-    boolean value:
-
--
-                            flags <= bxxx010xx
-                            flags .gt. bxxx100xx
-                            flags .le. b1xxxxxxx
--
-   
-    Notice the use of the x bit value to limit the range of  bits  being
-    compared.
-    
-    It  is  not necessary to specify the leading (most significant) zero
-    (0) bits in the mask, as shown in the second expression above.
-    
-    Bit wise AND, OR and NOT operations are  also  possible  on  two  or
-    more  bit  fields  using  the  '\&'(AND),  '$|$'(OR),  and the '!'(NOT)
-    operators. All of these operators result in a bit  field  which  can
-    then be used with the equal operator. For example:
-
--
-                          (!flags) == b1101100
-                          (flags & b1000001) == bx000001
--
-
-    Bit  fields can be appended as well using the '+' operator.  Strings
-    can be concatenated this way, too.
-    
-***3.  Vector Columns
-
-    Vector columns can also be used  in  building  the  expression.   No
-    special  syntax  is required if one wants to operate on all elements
-    of the vector.  Simply use the column name as for a  scalar  column.
-    Vector  columns  can  be  freely  intermixed  with scalar columns or
-    constants in virtually all expressions.  The result will be  of  the
-    same dimension as the vector.  Two vectors in an expression, though,
-    need to  have  the  same  number  of  elements  and  have  the  same
-    dimensions.   The  only  places  a vector column cannot be used (for
-    now, anyway) are the SAO  region  functions  and  the  NEAR  boolean
-    function.
-
-    Arithmetic and logical operations are all performed on an element by
-    element basis.  Comparing two vector columns,  eg  "COL1  ==  COL2",
-    thus  results  in  another vector of boolean values indicating which
-    elements of the two vectors are equal.  
-
-    Eight functions are available that operate on a vector and return a
-    scalar result:
--
-    "minimum"      MIN(V)          "maximum"               MAX(V)
-    "average"      AVERAGE(V)      "median"                MEDIAN(V)
-    "summation"    SUM(V)          "standard deviation"    STDDEV(V)
-    "# of values"  NELEM(V)        "# of non-null values"  NVALID(V)
--
-    where V represents the name of a vector column or a manually 
-    constructed vector using curly brackets as described below.  The
-    first 6 of these functions ignore any null values in the vector when
-    computing the result.  The STDDEV() function computes the sample 
-    standard deviation, i.e. it is proportional to 1/SQRT(N-1) instead 
-    of 1/SQRT(N), where N is NVALID(V).
-    
-    The SUM function literally sums all  the elements in x,  returning a 
-    scalar value.   If x  is  a  boolean  vector, SUM returns the number
-    of TRUE elements. The NELEM function  returns the number of elements
-    in vector x whereas NVALID return the number of non-null elements in
-    the  vector.   (NELEM  also  operates  on  bit  and string  columns, 
-    returning their column widths.)  As an example, to  test whether all 
-    elements of two vectors satisfy a  given logical comparison, one can
-    use the expression
--
-              SUM( COL1 > COL2 ) == NELEM( COL1 )
--
-
-    which will return TRUE if all elements  of  COL1  are  greater  than
-    their corresponding elements in COL2.
-    
-    To  specify  a  single  element  of  a  vector, give the column name
-    followed by  a  comma-separated  list  of  coordinates  enclosed  in
-    square  brackets.  For example, if a vector column named PHAS exists
-    in the table as a one dimensional, 256  component  list  of  numbers
-    from  which  you  wanted to select the 57th component for use in the
-    expression, then PHAS[57] would do the  trick.   Higher  dimensional
-    arrays  of  data  may appear in a column.  But in order to interpret
-    them, the TDIMn keyword must appear in the header.  Assuming that  a
-    (4,4,4,4)  array  is packed into each row of a column named ARRAY4D,
-    the  (1,2,3,4)  component  element  of  each  row  is  accessed   by 
-    ARRAY4D[1,2,3,4].    Arrays   up   to   dimension  5  are  currently 
-    supported.  Each vector index can itself be an expression,  although
-    it  must  evaluate  to  an  integer  value  within the bounds of the
-    vector.  Vector columns which contain spaces or arithmetic operators
-    must   have   their   names  enclosed  in  "\$"  characters  as  with 
-    \$ARRAY-4D\$[1,2,3,4].
-    
-    A  more  C-like  syntax  for  specifying  vector  indices  is   also 
-    available.   The element used in the preceding example alternatively
-    could be specified with the syntax  ARRAY4D[4][3][2][1].   Note  the
-    reverse  order  of  indices  (as in C), as well as the fact that the
-    values are still ones-based (as  in  Fortran  --  adopted  to  avoid
-    ambiguity  for  1D vectors).  With this syntax, one does not need to
-    specify all of the indices.  To  extract  a  3D  slice  of  this  4D
-    array, use ARRAY4D[4].
-    
-    Variable-length vector columns are not supported.
-    
-    Vectors can  be manually constructed  within the expression  using a
-    comma-separated list of  elements surrounded by curly braces ('\{\}').
-    For example, '\{1,3,6,1\}' is a 4-element vector containing the values
-    1, 3, 6, and 1.  The  vector can contain  only boolean, integer, and
-    real values (or expressions).  The elements will  be promoted to the
-    highest  datatype   present.  Any   elements   which  are themselves
-    vectors, will be expanded out with  each of its elements becoming an
-    element in the constructed vector.
-
-***4.  Good Time Interval Filtering
-
-    A common filtering method involves selecting rows which have a time
-    value which lies within what is called a Good Time Interval or GTI.
-    The time intervals are defined in a separate FITS table extension
-    which contains 2 columns giving the start and stop time of each
-    good interval.  The filtering operation accepts only those rows of
-    the input table which have an associated time which falls within
-    one of the time intervals defined in the GTI extension. A high
-    level function, gtifilter(a,b,c,d), is available which evaluates
-    each row of the input table  and returns TRUE  or FALSE depending
-    whether the row is inside or outside the  good time interval.  The
-    syntax is
--
-      gtifilter( [ "gtifile" [, expr [, "STARTCOL", "STOPCOL" ] ] ] )
--
-    where  each "[]" demarks optional parameters.  Note that  the quotes
-    around the gtifile and START/STOP column are required.  Either single
-    or double quotes may be used.  In cases where this expression is 
-    entered on the Unix command line, enclose the entire expression in
-    double quotes, and then use single quotes within the expression to
-    enclose the 'gtifile' and other terms.  It is also usually possible
-    to do the reverse, and enclose the whole expression in single quotes
-    and then use double quotes within the expression.  The gtifile,
-    if specified,  can be blank  ("") which will  mean to use  the first
-    extension  with   the name "*GTI*"  in   the current  file,  a plain
-    extension  specifier (eg, "+2",  "[2]", or "[STDGTI]") which will be
-    used  to  select  an extension  in  the current  file, or  a regular
-    filename with or without an extension  specifier which in the latter
-    case  will mean to  use the first  extension  with an extension name
-    "*GTI*".  Expr can be   any arithmetic expression, including  simply
-    the time  column  name.  A  vector  time expression  will  produce a
-    vector boolean  result.  STARTCOL and  STOPCOL are the  names of the
-    START/STOP   columns in the    GTI extension.  If   one  of them  is
-    specified, they both  must be.
-
-    In  its  simplest form, no parameters need to be provided -- default
-    values will be used.  The expression "gtifilter()" is equivalent to
--   
-       gtifilter( "", TIME, "*START*", "*STOP*" )
--    
-    This will search the current file for a GTI  extension,  filter  the
-    TIME  column in the current table, using START/STOP times taken from
-    columns in the GTI  extension  with  names  containing  the  strings
-    "START"  and "STOP".  The wildcards ('*') allow slight variations in
-    naming conventions  such  as  "TSTART"  or  "STARTTIME".   The  same
-    default  values  apply for unspecified parameters when the first one
-    or  two  parameters  are  specified.   The  function   automatically 
-    searches   for   TIMEZERO/I/F   keywords  in  the  current  and  GTI 
-    extensions, applying a relative time offset, if necessary.
-
-***5.  Spatial Region Filtering
-
-    Another common  filtering method selects rows based on whether the
-    spatial position associated with each row is located within a given 
-    2-dimensional region.  The syntax for this high-level filter is
--
-       regfilter( "regfilename" [ , Xexpr, Yexpr [ , "wcs cols" ] ] )
--
-    where each "[]" demarks optional parameters. The region file name
-    is required and must be  enclosed in quotes.  The remaining
-    parameters are optional.  There are 2 supported formats for the
-    region file: ASCII file or FITS binary table.  The region file 
-    contains a list of one or more geometric shapes (circle,
-    ellipse, box, etc.) which defines a region on the celestial sphere
-    or an area within a particular 2D image.  The region file is
-    typically generated using an image display program such as fv/POW
-    (distribute by the HEASARC), or ds9 (distributed by the Smithsonian
-    Astrophysical Observatory).  Users should refer to the documentation
-    provided with these programs for more details on the syntax used in
-    the region files.  The FITS region file format is defined in a document
-    available from the FITS Support Office at 
-    http://fits.gsfc.nasa.gov/ registry/ region.html
-
-    In its simplest form, (e.g., regfilter("region.reg") ) the
-    coordinates in the default 'X' and 'Y' columns will be used to
-    determine if each row is inside or outside the area specified in
-    the region file.  Alternate position column names, or expressions,
-    may be entered if needed, as in
--
-        regfilter("region.reg", XPOS, YPOS)
--
-    Region filtering can be applied most unambiguously if the positions
-    in the region file and in the table to be filtered are both give in
-    terms of absolute celestial coordinate units.  In this case the
-    locations and sizes of the geometric shapes in the region file are
-    specified in angular units on the sky (e.g., positions given in
-    R.A. and Dec.  and sizes in arcseconds or arcminutes).  Similarly,
-    each row of the filtered table will have a celestial coordinate
-    associated with it.  This association is usually implemented using
-    a set of so-called 'World Coordinate System' (or WCS) FITS keywords
-    that define the coordinate transformation that must be applied to
-    the values in the 'X' and 'Y' columns to calculate the coordinate.
-
-    Alternatively, one can perform spatial filtering using unitless
-    'pixel' coordinates for the regions and row positions.  In this
-    case the user must be careful to ensure that the positions in the 2
-    files are self-consistent.  A typical problem is that the region
-    file may be generated using a binned image, but the unbinned
-    coordinates are given in the event table.  The ROSAT events files,
-    for example, have X and Y pixel coordinates that range from 1 -
-    15360.  These coordinates are typically binned by a factor of 32 to
-    produce a 480x480 pixel image.  If one then uses a region file
-    generated from this image (in image pixel units) to filter the
-    ROSAT events file, then the X and Y column values must be converted
-    to corresponding pixel units as in:
--
-        regfilter("rosat.reg", X/32.+.5, Y/32.+.5)
--
-    Note that this binning conversion is not necessary if the region
-    file is specified using celestial coordinate units instead of pixel
-    units because CFITSIO is then able to directly compare the
-    celestial coordinate of each row in the table with the celestial
-    coordinates in the region file without having to know anything
-    about how the image may have been binned.
-
-    The last "wcs cols" parameter should rarely be needed. If supplied,
-    this  string contains the names of the 2 columns (space or comma
-    separated) which have the associated WCS keywords. If not supplied,
-    the filter  will scan the X  and Y expressions for column names.
-    If only one is found in each  expression, those columns will be
-    used, otherwise an error will be returned.
-
-    These region shapes are supported (names are case insensitive):
--
-       Point         ( X1, Y1 )               <- One pixel square region
-       Line          ( X1, Y1, X2, Y2 )       <- One pixel wide region
-       Polygon       ( X1, Y1, X2, Y2, ... )  <- Rest are interiors with
-       Rectangle     ( X1, Y1, X2, Y2, A )       | boundaries considered
-       Box           ( Xc, Yc, Wdth, Hght, A )   V within the region
-       Diamond       ( Xc, Yc, Wdth, Hght, A )
-       Circle        ( Xc, Yc, R )
-       Annulus       ( Xc, Yc, Rin, Rout )
-       Ellipse       ( Xc, Yc, Rx, Ry, A )
-       Elliptannulus ( Xc, Yc, Rinx, Riny, Routx, Routy, Ain, Aout )
-       Sector        ( Xc, Yc, Amin, Amax )
--
-    where (Xc,Yc) is  the coordinate of  the shape's center; (X\#,Y\#) are
-    the coordinates  of the shape's edges;  Rxxx are the shapes' various
-    Radii or semi-major/minor  axes; and Axxx  are the angles of rotation
-    (or bounding angles for Sector) in degrees.  For rotated shapes, the
-    rotation angle  can  be left  off, indicating  no rotation.   Common
-    alternate  names for the regions  can also be  used: rotbox = box;
-    rotrectangle = rectangle;  (rot)rhombus = (rot)diamond;  and pie
-    = sector.  When a  shape's name is  preceded by a minus sign, '-',
-    the defined region  is instead the area  *outside* its boundary (ie,
-    the region is inverted).  All the shapes within a single region
-    file are OR'd together to create the region, and the order is
-    significant. The overall way of looking at region files is that if
-    the first region is an excluded region then a dummy included region
-    of the whole detector is inserted in the front. Then each region
-    specification as it is processed overrides any selections inside of
-    that region specified by previous regions. Another way of thinking
-    about this is that if a previous excluded region is completely
-    inside of a subsequent included region the excluded region is
-    ignored.
-
-    The positional coordinates may be given either in pixel units,
-    decimal degrees or hh:mm:ss.s, dd:mm:ss.s units.  The shape sizes
-    may be given in pixels, degrees, arcminutes, or arcseconds.  Look
-    at examples of region file produced by fv/POW or ds9 for further
-    details of the region file format.
-
-    There are three functions that are primarily for use with SAO region
-    files and the  FSAOI  task, but they  can  be  used  directly.  They
-    return  a  boolean true   or  false  depending   on  whether a   two
-    dimensional point is in the region or not:
--
-    "point in a circular region"
-          circle(xcntr,ycntr,radius,Xcolumn,Ycolumn)
-    
-    "point in an elliptical region"
-         ellipse(xcntr,ycntr,xhlf_wdth,yhlf_wdth,rotation,Xcolumn,Ycolumn)
-    
-    "point in a rectangular region"
-             box(xcntr,ycntr,xfll_wdth,yfll_wdth,rotation,Xcolumn,Ycolumn)
-    
-    where 
-       (xcntr,ycntr) are the (x,y) position of the center of the region
-       (xhlf_wdth,yhlf_wdth) are the (x,y) half widths of the region
-       (xfll_wdth,yfll_wdth) are the (x,y) full widths of the region
-       (radius) is half the diameter of the circle
-       (rotation) is the angle(degrees) that the region is rotated with
-             respect to (xcntr,ycntr)
-       (Xcoord,Ycoord) are the (x,y) coordinates to test, usually column
-             names
-       NOTE: each parameter can itself be an expression, not merely a
-             column name or constant.

-**K.   Binning or Histogramming Specification
-
-The optional binning specifier is enclosed in square brackets and can
-be distinguished from a general row filter specification by the fact
-that it begins with the keyword 'bin'  not immediately followed by an
-equals sign.  When binning is specified, a temporary N-dimensional FITS
-primary array is created by computing the histogram of the values in
-the specified columns of a FITS table extension.  After the histogram
-is computed the input FITS file containing the table is then closed and
-the temporary FITS primary array is opened and passed to the
-application program.  Thus, the application program never sees the
-original FITS table and only sees the image in the new temporary file
-(which has no additional extensions).  Obviously, the application
-program must be expecting to open a FITS image and not a FITS table in
-this case.
-
-The data type of the FITS histogram image may be specified by appending
-'b' (for 8-bit byte), 'i' (for 16-bit integers), 'j' (for 32-bit
-integer), 'r' (for 32-bit floating points), or 'd' (for 64-bit double
-precision floating point)  to the 'bin' keyword (e.g. '[binr X]'
-creates a real floating point image).  If the datatype is not
-explicitly specified then a 32-bit integer image will be created by
-default, unless the weighting option is also specified in which case
-the image will have a 32-bit floating point data type by default.
-
-The histogram image may have from 1 to 4 dimensions (axes), depending
-on the number of columns that are specified.  The general form of the
-binning specification is:
--
- [bin{bijrd}  Xcol=min:max:binsize, Ycol= ..., Zcol=..., Tcol=...; weight]
--
-in which up to 4 columns, each corresponding to an axis of the image,
-are listed. The column names are case insensitive, and the column
-number may be given instead of the name, preceded by a pound sign
-(e.g., [bin \#4=1:512]).  If the column name is not specified, then
-CFITSIO will first try to use the 'preferred column' as specified by
-the CPREF keyword if it exists (e.g., 'CPREF = 'DETX,DETY'), otherwise
-column names 'X', 'Y', 'Z', and 'T' will be assumed for each of the 4
-axes, respectively.  In cases where the column name could be confused
-with an arithmetic expression, enclose the column name in parentheses to
-force the name to be interpreted literally.
-
-Each column name may be followed by an equals sign and then the lower
-and upper range of the histogram, and the size of the histogram bins,
-separated by colons.  Spaces are allowed before and after the equals
-sign but not within the 'min:max:binsize' string.  The min, max and
-binsize values may be integer or floating point numbers, or they may be
-the names of keywords in the header of the table.  If the latter, then
-the value of that keyword is substituted into the expression.
-
-Default values for the min, max and binsize quantities will be
-used if not explicitly given in the binning expression as shown
-in these examples:
--
-    [bin x = :512:2]  - use default minimum value
-    [bin x = 1::2]    - use default maximum value
-    [bin x = 1:512]   - use default bin size
-    [bin x = 1:]      - use default maximum value and bin size
-    [bin x = :512]    - use default minimum value and bin size
-    [bin x = 2]       - use default minimum and maximum values
-    [bin x]           - use default minimum, maximum and bin size
-    [bin 4]           - default 2-D image, bin size = 4 in both axes
-    [bin]             - default 2-D image
--
-CFITSIO  will use the value of the TLMINn, TLMAXn, and TDBINn keywords,
-if they exist, for the default min, max, and binsize, respectively.  If
-they do not exist then CFITSIO will use the actual minimum and maximum
-values in the column for the histogram min and max values.  The default
-binsize will be set to 1, or (max - min) / 10., whichever is smaller,
-so that the histogram will have at least 10 bins along each axis.
-
-A shortcut notation is allowed if all the columns/axes have the same
-binning specification.  In this case all the column names may be listed
-within parentheses, followed by the (single) binning specification, as
-in:
--
-    [bin (X,Y)=1:512:2]
-    [bin (X,Y) = 5]
--
-
-The optional weighting factor is the last item in the binning specifier
-and, if present, is separated from the list of columns by a
-semi-colon.  As the histogram is accumulated, this weight is used to
-incremented the value of the appropriated bin in the histogram.  If the
-weighting factor is not specified, then the default weight = 1 is
-assumed.  The weighting factor may be a constant integer or floating
-point number, or the name of a keyword containing the weighting value.
-Or the weighting factor may be the name of a table column in which case
-the value in that column, on a row by row basis, will be used.
-
-In some cases, the column or keyword may give the reciprocal of the
-actual weight value that is needed.  In this case, precede the weight
-keyword or column name by a slash '/' to tell CFITSIO to use the
-reciprocal of the value when constructing the histogram. 
-
-For  complex or commonly  used  histograms, one  can also  place its
-description  into  a  text  file and  import   it  into  the binning
-specification  using the  syntax '[bin  @filename.txt]'.  The file's
-contents  can extend over   multiple lines, although  it must still
-conform to the  no-spaces rule  for the min:max:binsize syntax and each
-axis specification must still be comma-separated.  Any lines in the
-external text file that begin with 2 slash characters ('//') will be
-ignored and may be used to add comments into the file.
-
- Examples:
-
--
-    [bini detx, dety]                - 2-D, 16-bit integer histogram
-                                       of DETX and DETY columns, using
-                                       default values for the histogram
-                                       range and binsize
-
-    [bin (detx, dety)=16; /exposure] - 2-D, 32-bit real histogram of DETX
-                                       and DETY columns with a bin size = 16
-                                       in both axes. The histogram values
-                                       are divided by the EXPOSURE keyword
-                                       value.
-
-    [bin time=TSTART:TSTOP:0.1]      - 1-D lightcurve, range determined by
-                                       the TSTART and TSTOP keywords, 
-                                       with 0.1 unit size bins.  
- 
-    [bin pha, time=8000.:8100.:0.1]  - 2-D image using default binning
-                                       of the PHA column for the X axis,
-                                       and 1000 bins in the range 
-                                       8000. to 8100. for the Y axis.
-    
-    [bin @binFilter.txt]             - Use the contents of the text file
-                                       binFilter.txt for the binning
-                                       specifications.

-*V.  Template Files
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described in the following sections.
-
-**A   Detailed Template Line Format
-
-The format of each ASCII template line closely follows the format of a
-FITS keyword record:
--
-  KEYWORD = KEYVALUE / COMMENT
--
-except that free format may be used (e.g., the equals sign may appear
-at any position in the line) and TAB characters are allowed and are
-treated the same as space characters.  The KEYVALUE and COMMENT fields
-are optional.  The equals sign character is also optional, but it is
-recommended that it be included for clarity.  Any template line that
-begins with the pound '\#' character is ignored by the template parser
-and may be use to insert comments into the template file itself.
-
-The KEYWORD name field is limited to 8 characters in length and only
-the letters A-Z, digits 0-9, and the hyphen and underscore characters
-may be used, without any embedded spaces. Lowercase letters in the
-template keyword name will be converted to uppercase.  Leading spaces
-in the template line preceding the keyword name are generally ignored,
-except if the first 8 characters of a template line are all blank, then
-the entire line is treated as a FITS comment keyword (with a blank
-keyword name) and is copied verbatim into the FITS header.
-
-The KEYVALUE field may have any allowed  FITS  data type: character
-string, logical, integer, real, complex integer, or complex real.  The
-character string values need not be enclosed in single quote characters
-unless they are necessary to distinguish the string from a different
-data type (e.g.  2.0 is a real but '2.0' is a string).  The keyword has
-an undefined (null) value if the template record only contains blanks
-following the "=" or between the "=" and the "/" comment field
-delimiter.
-
-String keyword values longer than 68 characters (the maximum length
-that will fit in a single FITS keyword record) are permitted using the
-CFITSIO long string convention. They can either be specified as a
-single long line in the template, or by using multiple lines where the
-continuing lines contain the 'CONTINUE' keyword, as in this example:
-- 
-  LONGKEY = 'This is a long string value that is contin&'
-  CONTINUE  'ued over 2 records' / comment field goes here
--
-The format of template lines with CONTINUE keyword is very strict:  3
-spaces must follow CONTINUE and the rest of the line is copied verbatim
-to the FITS file.
-
-The start of the optional COMMENT field must be preceded by "/", which
-is used to separate it from the keyword value field. Exceptions are if
-the KEYWORD name field contains COMMENT, HISTORY, CONTINUE, or if the
-first 8 characters of the template line are blanks.
-
-More than one Header-Data Unit (HDU) may be defined in the template
-file.  The start of an HDU definition is denoted with a SIMPLE or
-XTENSION template line:
-
-1) SIMPLE begins a Primary HDU definition. SIMPLE may only appear as
-the  first keyword in the template file. If the template file begins
-with XTENSION instead of SIMPLE, then a default empty Primary HDU is
-created, and the template is then assumed to define the keywords
-starting with the first extension following the Primary HDU.
-
-2) XTENSION marks the beginning of a new extension HDU definition.  The
-previous HDU will be closed at this point and processing of the next
-extension begins.
-
-**B   Auto-indexing of Keywords
-
-If a template keyword name ends with a "\#" character, it is said to be
-'auto-indexed'.   Each "\#" character will be replaced by the current
-integer index value, which gets reset = 1 at the start of each new HDU
-in the file (or 7 in the special case of a GROUP definition).  The
-FIRST indexed keyword in each template HDU definition is used as the
-'incrementor';  each subsequent occurrence of this SAME keyword will
-cause the index value to be incremented.  This behavior can be rather
-subtle, as illustrated in the following examples in which the TTYPE
-keyword is the incrementor in both cases:
--
-  TTYPE# = TIME
-  TFORM# = 1D
-  TTYPE# = RATE
-  TFORM# = 1E
--
-will create TTYPE1, TFORM1, TTYPE2, and TFORM2 keywords.  But if the
-template looks like,
--
-  TTYPE# = TIME
-  TTYPE# = RATE
-  TFORM# = 1D
-  TFORM# = 1E
--
-this results in a FITS files with  TTYPE1, TTYPE2, TFORM2, and TFORM2,
-which is probably not what was intended!
-
-**C   Template Parser Directives
-
-In addition to the template lines which define individual keywords, the
-template parser recognizes 3 special directives which are each preceded
-by the backslash character:  \verb+ \include, \group+, and \verb+ \end+.
-
-The 'include' directive must be followed by a filename. It forces the
-parser to temporarily stop reading the current template file and begin
-reading the include file. Once the parser reaches the end of the
-include file it continues parsing the current template file.  Include
-files can be nested, and HDU definitions can span multiple template
-files.
-
-The start of a GROUP definition is denoted with the 'group' directive,
-and the end of a GROUP definition is denoted with the 'end' directive.
-Each GROUP contains 0 or more member blocks (HDUs or GROUPs). Member
-blocks of type GROUP can contain their own member blocks. The GROUP
-definition itself occupies one FITS file HDU of special type (GROUP
-HDU), so if a template specifies 1 group with 1 member HDU like:
--
-\group
-grpdescr = 'demo'
-xtension bintable
-# this bintable has 0 cols, 0 rows
-\end
--
-then the parser creates a FITS file with 3 HDUs :
--
-1) dummy PHDU
-2) GROUP HDU (has 1 member, which is bintable in HDU number 3)
-3) bintable (member of GROUP in HDU number 2)
--
-Technically speaking, the GROUP HDU is a BINTABLE with 6 columns. Applications
-can define additional columns in a GROUP HDU using TFORMn and TTYPEn
-(where n is 7, 8, ....) keywords or their auto-indexing equivalents.
-
-For a more complicated example of a template file using the group directives,
-look at the sample.tpl file that is included in the CFITSIO distribution.
-
-**D   Formal Template Syntax
-
-The template syntax can formally be defined as follows:
--
-    TEMPLATE = BLOCK [ BLOCK ... ]
-
-       BLOCK = { HDU | GROUP }
-
-       GROUP = \GROUP [ BLOCK ... ] \END
-
-         HDU = XTENSION [ LINE ... ] { XTENSION | \GROUP | \END | EOF }
-
-        LINE = [ KEYWORD [ = ] ] [ VALUE ] [ / COMMENT ]
-
-    X ...     - X can be present 1 or more times
-    { X | Y } - X or Y
-    [ X ]     - X is optional
--
-
-At the topmost level, the template defines 1 or more template blocks. Blocks
-can be either HDU (Header Data Unit) or a GROUP. For each block the parser
-creates 1 (or more for GROUPs) FITS file HDUs.
-
-
-**E   Errors
-
-In general the fits\_execute\_template() function tries to be as atomic
-as possible, so either everything is done or nothing is done. If an
-error occurs during parsing of the template, fits\_execute\_template()
-will (try to) delete the top level BLOCK (with all its children if any)
-in which the error occurred, then it will stop reading the template file
-and it will return with an error.
-
-**F   Examples
-
-1. This template file will create a 200 x 300 pixel image, with 4-byte
-integer pixel values, in the primary HDU:
--
-  SIMPLE = T 
-  BITPIX = 32
-  NAXIS = 2     / number of dimensions
-  NAXIS1 = 100  / length of first axis
-  NAXIS2 = 200  / length of second axis
-  OBJECT = NGC 253 / name of observed object
--
-The allowed values of BITPIX are 8, 16, 32, -32, or -64,
-representing, respectively, 8-bit integer, 16-bit integer, 32-bit
-integer, 32-bit floating point, or 64 bit floating point pixels.
-
-2.  To create a FITS  table, the template first needs to include
-XTENSION = TABLE or BINTABLE to define whether it is an ASCII or binary
-table, and NAXIS2 to define the number of rows in the table.  Two
-template lines are then needed to define the name (TTYPEn) and FITS data
-format (TFORMn) of the columns, as in this example:
--
-  xtension = bintable
-  naxis2 = 40
-  ttype# = Name
-  tform# = 10a
-  ttype# = Npoints
-  tform# = j
-  ttype# = Rate
-  tunit# = counts/s
-  tform# = e
--
-The above example defines a null primary array followed by a 40-row
-binary table extension with 3 columns called 'Name', 'Npoints', and
-'Rate', with data formats of '10A' (ASCII character string), '1J'
-(integer) and '1E' (floating point), respectively.  Note that the other
-required FITS keywords (BITPIX, NAXIS, NAXIS1, PCOUNT, GCOUNT, TFIELDS,
-and END) do not need to be explicitly defined in the template because
-their values can be inferred from the other keywords in the template.
-This example also illustrates that the templates are generally
-case-insensitive (the keyword names and TFORMn values are converted to
-upper-case in the FITS file) and that string keyword values generally
-do not need to be enclosed in quotes.

-/*=============================================================================
-*
-*       The following wtbarr typedef is used in the fits_read_wcstab() routine,
-*       which is intended for use with the WCSLIB library written by Mark
-*       Calabretta, http://www.atnf.csiro.au/~mcalabre/index.html
-*
-*       In order to maintain WCSLIB and CFITSIO as independent libraries it
-*       was not permissible for any CFITSIO library code to include WCSLIB
-*       header files, or vice versa.  However, the CFITSIO function
-*       fits_read_wcstab() accepts an array of structs defined by wcs.h within
-*       WCSLIB.  The problem then was to define this struct within fitsio.h
-*       without including wcs.h, especially noting that wcs.h will often (but
-*       not always) be included together with fitsio.h in an applications
-*       program that uses fits_read_wcstab().
-*
-*       Of the various possibilities, the solution adopted was for WCSLIB to
-*       define "struct wtbarr" while fitsio.h defines "typedef wtbarr", a
-*       untagged struct with identical members.  This allows both wcs.h and
-*       fitsio.h to define a wtbarr data type without conflict by virtue of
-*       the fact that structure tags and typedef names share different
-*       namespaces in C. Therefore, declarations within WCSLIB look like
-*
-*          struct wtbarr *w;
-*
-*       while within CFITSIO they are simply
-*
-*          wtbarr *w;
-*
-*       but as suggested by the commonality of the names, these are really the
-*       same aggregate data type.  However, in passing a (struct wtbarr *) to
-*       fits_read_wcstab() a cast to (wtbarr *) is formally required.

-\chapter{Introduction }
-\pagenumbering{arabic}
-
-This document describes the Fortran-callable subroutine interface that
-is provided as part of the CFITSIO library (which is written in ANSI
-C).  This is a companion document to the CFITSIO User's Guide which
-should be consulted for further information about the underlying
-CFITSIO library.  In the remainder of this document, the terms FITSIO
-and CFITSIO are interchangeable and refer to the same library.
-
-FITSIO/CFITSIO is a machine-independent library of routines for reading
-and writing data files in the FITS (Flexible Image Transport System)
-data format.  It can also read IRAF format image files and raw binary
-data arrays by converting them on the fly into a virtual FITS format
-file.  This library was written to provide a powerful yet simple
-interface for accessing FITS files which will run on most commonly used
-computers and workstations. FITSIO supports all the features described
-in the official NOST definition of the FITS format and can read and
-write all the currently defined types of extensions, including ASCII
-tables (TABLE), Binary tables (BINTABLE) and IMAGE extensions. The
-FITSIO subroutines insulate the programmer from having to deal with the
-complicated formatting details in the FITS file, however, it is assumed
-that users have a general knowledge about the structure and usage of
-FITS files.
-
-The CFITSIO package was initially developed by the HEASARC (High Energy
-Astrophysics Science Archive Research Center) at the NASA Goddard Space
-Flight Center to convert various existing and newly acquired
-astronomical data sets into FITS format and to further analyze data
-already in FITS format.  New features continue to be added to CFITSIO
-in large part due to contributions of ideas or actual code from users
-of the package.  The Integral Science Data Center in Switzerland, and
-the XMM/ESTEC project in The Netherlands made especially significant
-contributions that resulted in many of the new features that appeared
-in v2.0 of CFITSIO.

-example programs are available on the World-Wide Web or via anonymous

-\chapter{ Creating FITSIO/CFITSIO }
-
-
-\section{Building the Library}
-
-To use the FITSIO subroutines one must first build the CFITSIO library,
-which requires a C compiler. gcc is ideal, or most other ANSI-C
-compilers will also work.  The CFITSIO code is contained in about 40 C
-source files (*.c) and header files (*.h). On VAX/VMS systems 2
-assembly-code files (vmsieeed.mar and vmsieeer.mar) are also needed.
-
-The Fortran interface subroutines to the C CFITSIO routines are located
-in the f77\_wrap1.c, through f77\_wrap4.c files.  These are relatively simple
-'wrappers' that translate the arguments in the Fortran subroutine into
-the appropriate format for the corresponding C routine.  This
-translation is performed transparently to the user by a set of C macros
-located in the cfortran.h file.  Unfortunately cfortran.h does not
-support every combination of C and Fortran compilers so the Fortran
-interface is not supported on all platforms. (see further notes below).
-
-A standard combination of C and Fortran compilers will be assumed by
-default, but one may also specify a particular Fortran compiler by
-doing:
-
-\begin{verbatim}
- >  setenv CFLAGS -DcompilerName=1
-\end{verbatim}
-(where 'compilerName' is the name of the compiler) before running
-the configure command.  The currently recognized compiler
-names are:
-
-\begin{verbatim}
- g77Fortran
- IBMR2Fortran
- CLIPPERFortran
- pgiFortran
- NAGf90Fortran
- f2cFortran
- hpuxFortran
- apolloFortran
- sunFortran
- CRAYFortran
- mipsFortran
- DECFortran
- vmsFortran
- CONVEXFortran
- PowerStationFortran
- AbsoftUNIXFortran
- AbsoftProFortran
- SXFortran
-\end{verbatim}
-Alternatively, one may edit the CFLAGS line in the Makefile to add the
-'-DcompilerName' flag after running the './configure' command.
-
-The CFITSIO library is built on Unix systems by typing:
-
-\begin{verbatim}
- >  ./configure [--prefix=/target/installation/path]
-                [--enable-sse2] [--enable-ssse3]
- >  make          (or  'make shared')
- >  make install  (this step is optional)
-\end{verbatim}
-at the operating system prompt.  The configure command customizes the
-Makefile for the particular system, then the `make' command compiles the
-source files and builds the library.  Type `./configure' and not simply
-`configure' to ensure that the configure script in the current directory
-is run and not some other system-wide configure script.  The optional
-'prefix' argument to configure gives the path to the directory where
-the CFITSIO library and include files should be installed via the later
-'make install' command. For example,
-
-\begin{verbatim}
-   > ./configure --prefix=/usr1/local
-\end{verbatim}
-will cause the 'make install' command to copy the CFITSIO libcfitsio file
-to /usr1/local/lib and the necessary include files to /usr1/local/include
-(assuming of course that the  process has permission to write to these
-directories).
-
-The optional --enable-sse2 and --enable-ssse3 flags will cause configure to
-attempt to build CFITSIO using faster byte-swapping algorithms.
-See the "Optimizing Programs" section of this manual for
-more information about these options.
-
-By default, the Makefile will be configured to build the set of Fortran-callable
-wrapper routines whose calling sequences are described later in this
-document.
-
-The 'make shared' option builds a shared or dynamic version of the
-CFITSIO library.  When using the shared library the executable code is
-not copied into your program at link time and instead the program
-locates the necessary library code at run time, normally through
-LD\_LIBRARY\_PATH or some other method. The advantages of using a shared
-library are:
-
-\begin{verbatim}
-   1.  Less disk space if you build more than 1 program
-   2.  Less memory if more than one copy of a program using the shared
-       library is running at the same time since the system is smart
-       enough to share copies of the shared library at run time.
-   3.  Possibly easier maintenance since a new version of the shared
-       library can be installed without relinking all the software
-       that uses it (as long as the subroutine names and calling
-       sequences remain unchanged).
-   4.  No run-time penalty.
-\end{verbatim}
-The disadvantages are:
-
-\begin{verbatim}
-   1. More hassle at runtime.  You have to either build the programs
-      specially or have LD_LIBRARY_PATH set right.
-   2. There may be a slight start up penalty, depending on where you are
-      reading the shared library and the program from and if your CPU is
-      either really slow or really heavily loaded.
-\end{verbatim}
-
-On HP/UX systems, the environment variable CFLAGS should be set
-to -Ae before running configure to enable "extended ANSI" features.
-
-It may not be possible to statically link programs that use CFITSIO on
-some platforms (namely, on Solaris 2.6) due to the network drivers
-(which provide FTP and HTTP access to FITS files).  It is possible to
-make both a dynamic and a static version of the CFITSIO library, but
-network file access will not be possible using the static version.
-
-On VAX/VMS and ALPHA/VMS systems the make\_gfloat.com command file may
-be executed to build the cfitsio.olb object library using the default
-G-floating point option for double variables.  The make\_dfloat.com and
-make\_ieee.com files may be used instead to build the library with the
-other floating point options. Note that the getcwd function that is
-used in the group.c module may require that programs using CFITSIO be
-linked with the ALPHA\$LIBRARY:VAXCRTL.OLB library.  See the example
-link line in the next section of this document.
-
-On Windows IBM-PC type platforms the situation is more complicated
-because of the wide variety of Fortran compilers that are available and
-because of the inherent complexities of calling the CFITSIO C routines
-from Fortran.  Two different versions of the CFITSIO dll library are
-available, compiled with the Borland C++ compiler and the Microsoft
-Visual C++ compiler, respectively, in the files
-cfitsiodll\_2xxx\_borland.zip and cfitsiodll\_3xxx\_vcc.zip, where
-'3xxx' represents the current release number.  Both these dll libraries
-contain a set of Fortran wrapper routines which may be compatible with
-some, but probably not all, available Fortran compilers.  To test if
-they are compatible, compile the program testf77.f and try linking to
-these dll libraries.  If these libraries do not work with a particular
-Fortran compiler, then there are 2 possible solutions.  The first
-solution would be to modify the file cfortran.h for that particular
-combination of C and Fortran compilers, and then rebuild the CFITSIO
-dll library.  This will require, however, a some expertise in
-mixed language programming.
-The other solution is to use the older v5.03 Fortran-77 implementation
-of FITSIO that is still available from the FITSIO web-site.  This
-version is no longer supported, but it does provide the basic functions
-for reading and writing FITS files and should be compatible with most
-Fortran compilers.
-
-CFITSIO has currently been tested on the following platforms:
-
-\begin{verbatim}
-  OPERATING SYSTEM           COMPILER
-   Sun OS                     gcc and cc (3.0.1)
-   Sun Solaris                gcc and cc
-   Silicon Graphics IRIX      gcc and cc
-   Silicon Graphics IRIX64    MIPS
-   Dec Alpha OSF/1            gcc and cc
-   DECstation  Ultrix         gcc
-   Dec Alpha OpenVMS          cc
-   DEC VAX/VMS                gcc and cc
-   HP-UX                      gcc
-   IBM AIX                    gcc
-   Linux                      gcc
-   MkLinux                    DR3
-   Windows 95/98/NT           Borland C++ V4.5
-   Windows 95/98/NT/ME/XP     Microsoft/Compaq Visual C++ v5.0, v6.0
-   Windows 95/98/NT           Cygwin gcc
-   OS/2                       gcc + EMX
-   MacOS 7.1 or greater       Metrowerks 10.+
-\end{verbatim}
-CFITSIO will probably run on most other Unix platforms.  Cray
-supercomputers are currently not supported.
-
-
-\section{Testing the Library}
-
-The CFITSIO library should be tested by building and running
-the testprog.c program that is included with the release.
-On Unix systems type:
-
-\begin{verbatim}
-    % make testprog
-    % testprog > testprog.lis
-    % diff testprog.lis testprog.out
-    % cmp testprog.fit testprog.std
-\end{verbatim}
- On VMS systems,
-(assuming cc is the name of the C compiler command), type:
-
-\begin{verbatim}
-    $ cc testprog.c
-    $ link testprog, cfitsio/lib, alpha$library:vaxcrtl/lib
-    $ run testprog
-\end{verbatim}
-The testprog program should produce a FITS file called `testprog.fit'
-that is identical to the `testprog.std' FITS file included with this
-release.  The diagnostic messages (which were piped to the file
-testprog.lis in the Unix example) should be identical to the listing
-contained in the file testprog.out.  The 'diff' and 'cmp' commands
-shown above should not report any differences in the files.  (There
-may be some minor formatting differences, such as the presence or
-absence of leading zeros, or 3 digit exponents in numbers,
-which can be ignored).
-
-The Fortran wrappers in CFITSIO may be tested with the testf77
-program.  On Unix systems the fortran compilation and link command
-may be called 'f77' or 'g77', depending on the system.
-
-\begin{verbatim}
-   % f77 -o testf77 testf77.f -L. -lcfitsio -lnsl -lsocket
- or
-   % f77 -f -o testf77 testf77.f -L. -lcfitsio    (under SUN O/S)
- or
-   % f77 -o testf77 testf77.f -Wl,-L. -lcfitsio -lm -lnsl -lsocket (HP/UX)
- or
-   % g77 -o testf77 -s testf77.f -lcfitsio -lcc_dynamic -lncurses (Mac OS-X)
-
-   % testf77 > testf77.lis
-   % diff testf77.lis testf77.out
-   % cmp testf77.fit testf77.std
-\end{verbatim}
-On machines running SUN O/S, Fortran programs must be compiled with the
-'-f' option to force double precision variables to be aligned on 8-byte
-boundaries to make the fortran-declared variables compatible with C.  A
-similar compiler option may be required on other platforms.  Failing to
-use this option may cause the program to crash on FITSIO routines that
-read or write double precision variables.
-
-On Windows platforms, linking Fortran programs with a C library
-often depends on the particular compilers involved.  Some users have
-found the following commands work when using the Intel Fortran compiler:
-
-\begin{verbatim}
-ifort /libs.dll cfitsio.lib /MD testf77.f /Gm
-
-or possibly,
-
-ifort /libs:dll cfitsio.lib /MD /fpp /extfpp:cfortran.h,fitsio.h
-    /iface:cvf testf77.f
-\end{verbatim}
-Also note that on some systems the output listing of the testf77
-program may differ slightly from the testf77.std template if leading
-zeros are not printed by default before the decimal point when using F
-format.
-
-A few other utility  programs are included with CFITSIO:
-
-\begin{verbatim}
-    speed - measures the maximum throughput (in MB per second)
-              for writing and reading FITS files with CFITSIO
-
-    listhead - lists all the header keywords in any FITS file
-
-    fitscopy - copies any FITS file (especially useful in conjunction
-                 with the CFITSIO's extended input filename syntax)
-
-    cookbook - a sample program that performs common read and
-                 write operations on a FITS file.
-
-    iter_a, iter_b, iter_c - examples of the CFITSIO iterator routine
-\end{verbatim}
-
-The first 4 of these utility programs can be compiled and linked by typing
-
-\begin{verbatim}
-   %  make program_name
-\end{verbatim}
-
-
-\section{Linking Programs with FITSIO}
-
-When linking applications software with the FITSIO library, several system libraries usually need to be specified on the link comman
-Unix systems, the most reliable way to determine what libraries are required
-is to type 'make testprog' and see what libraries the configure script has
-added.  The typical libraries that may need to be added are -lm (the math
-library) and -lnsl and -lsocket (needed only for FTP and HTTP file access).
-These latter 2 libraries are not needed on VMS and Windows platforms,
-because FTP file access is not currently supported on those platforms.
-
-Note that when upgrading to a newer version of CFITSIO it is usually
-necessary to recompile, as well as relink, the programs that use CFITSIO,
-because the definitions in fitsio.h often change.
-
-
-\section{Getting Started with FITSIO}
-
-In order to effectively use the FITSIO library as quickly as possible,
-it is recommended that new users follow these steps:
-
-1.  Read the following `FITS Primer' chapter for a brief
-overview of the structure of FITS files.  This is especially important
-for users who have not previously dealt with the FITS table and image
-extensions.
-
-2.  Write a simple program to read or write a FITS file using the Basic
-Interface routines.
-
-3.  Refer to the cookbook.f program that is included with this release
-for examples of routines that perform various common FITS file
-operations.
-
-4. Read Chapters 4 and 5 to become familiar with the conventions and
-advanced features of the FITSIO interface.
-
-5.  Scan through the more extensive set of routines that are provided
-in the `Advanced Interface'.  These routines perform more specialized
-functions than are provided by the Basic Interface routines.
-
-
-\section{Example Program}
-
-The following listing shows an example of how to use the FITSIO
-routines in a Fortran program.  Refer to the cookbook.f program that
-is included with the FITSIO distribution for examples of other
-FITS programs.
-
-\begin{verbatim}
-      program writeimage
-
-C     Create a FITS primary array containing a 2-D image
-
-      integer status,unit,blocksize,bitpix,naxis,naxes(2)
-      integer i,j,group,fpixel,nelements,array(300,200)
-      character filename*80
-      logical simple,extend
-
-      status=0
-C     Name of the FITS file to be created:
-      filename='ATESTFILE.FITS'
-
-C     Get an unused Logical Unit Number to use to create the FITS file
-      call ftgiou(unit,status)
-
-C     create the new empty FITS file
-      blocksize=1
-      call ftinit(unit,filename,blocksize,status)
-
-C     initialize parameters about the FITS image (300 x 200 16-bit integers)
-      simple=.true.
-      bitpix=16
-      naxis=2
-      naxes(1)=300
-      naxes(2)=200
-      extend=.true.
-
-C     write the required header keywords
-      call ftphpr(unit,simple,bitpix,naxis,naxes,0,1,extend,status)
-
-C     initialize the values in the image with a linear ramp function
-      do j=1,naxes(2)
-          do i=1,naxes(1)
-              array(i,j)=i+j
-          end do
-      end do
-
-C     write the array to the FITS file
-      group=1
-      fpixel=1
-      nelements=naxes(1)*naxes(2)
-      call ftpprj(unit,group,fpixel,nelements,array,status)
-
-C     write another optional keyword to the header
-      call ftpkyj(unit,'EXPOSURE',1500,'Total Exposure Time',status)
-
-C     close the file and free the unit number
-      call ftclos(unit, status)
-      call ftfiou(unit, status)
-      end
-\end{verbatim}

-\section{Acknowledgments}
-
-The development of many of the powerful features in CFITSIO was made
-possible through collaborations with many people or organizations from
-around the world.  The following, in particular, have made especially
-significant contributions:
-
-Programmers from the Integral Science Data Center, Switzerland (namely,
-Jurek Borkowski, Bruce O'Neel, and Don Jennings), designed the concept
-for the plug-in I/O drivers that was introduced with CFITSIO 2.0.  The
-use of `drivers' greatly simplified  the low-level I/O, which in turn
-made other new features in CFITSIO (e.g., support for compressed FITS
-files and support for IRAF format image files) much easier to
-implement.  Jurek Borkowski wrote the Shared Memory driver, and Bruce
-O'Neel wrote the drivers for accessing FITS files over the network
-using the FTP, HTTP, and ROOT protocols.
-
-The ISDC also provided the template parsing routines (written by Jurek
-Borkowski) and the hierarchical grouping routines (written by Don
-Jennings).  The ISDC DAL (Data Access Layer) routines are layered on
-top of CFITSIO and make extensive use of these features.
-
-Uwe Lammers (XMM/ESA/ESTEC, The Netherlands) designed the
-high-performance lexical parsing algorithm that is used to do
-on-the-fly filtering of FITS tables.  This algorithm essentially
-pre-compiles the user-supplied selection expression into a form that
-can be rapidly evaluated for each row.  Peter Wilson (RSTX, NASA/GSFC)
-then wrote the parsing routines used by CFITSIO based on Lammers'
-design, combined with other techniques such as the CFITSIO iterator
-routine to further enhance the data processing throughput.  This effort
-also benefited from a much earlier lexical parsing routine that was
-developed by Kent Blackburn (NASA/GSFC). More recently, Craig Markwardt
-(NASA/GSFC) implemented additional functions (median, average, stddev)
-and other enhancements to the lexical parser.
-
-The CFITSIO iterator function is loosely based on similar ideas
-developed for the XMM Data Access Layer.
-
-Peter Wilson (RSTX, NASA/GSFC) wrote the complete set of
-Fortran-callable wrappers for all the CFITSIO routines, which in turn
-rely on the CFORTRAN macro developed by Burkhard Burow.
-
-The syntax used by CFITSIO for filtering or binning input FITS files is
-based on ideas developed for the AXAF Science Center Data Model by
-Jonathan McDowell, Antonella Fruscione, Aneta Siemiginowska and Bill
-Joye. See http://heasarc.gsfc.nasa.gov/docs/journal/axaf7.html for
-further description of the AXAF Data Model.
-
-The file decompression code were taken directly from the gzip (GNU zip)
-program developed by Jean-loup Gailly and others.
-
-Doug Mink, SAO, provided the routines for converting IRAF format
-images into FITS format.
-
-Martin Reinecke (Max Planck Institute, Garching)) provided the modifications to
-cfortran.h that are necessary to support 64-bit integer values when calling
-C routines from fortran programs.  The cfortran.h macros were originally developed
-by Burkhard Burow (CERN).
-
-Julian Taylor (ESO, Garching) provided the fast byte-swapping algorithms
-that use the SSE2 and SSSE3 machine instructions available on x86\_64 CPUs.
-
-In addition, many other people have made valuable contributions to the
-development of CFITSIO.  These include (with apologies to others that may
-have inadvertently been omitted):

-\chapter{  A FITS Primer }
-
-This section gives a brief overview of the structure of FITS files.
-Users should refer to the documentation available from the NOST, as
-described in the introduction, for more detailed information on FITS
-formats.
-
-FITS was first developed in the late 1970's as a standard data
-interchange format between various astronomical observatories.  Since
-then FITS has become the defacto standard data format supported by most
-astronomical data analysis software packages.
-
-A FITS file consists of one or more Header + Data Units (HDUs), where
-the first HDU is called the `Primary HDU', or `Primary Array'.  The
-primary array contains an N-dimensional array of pixels, such as a 1-D
-spectrum, a 2-D image, or a 3-D data cube.  Six different primary
-datatypes are supported: Unsigned 8-bit bytes, 16, 32, and 64-bit signed
-integers, and 32 and 64-bit floating point reals.  FITS also has a
-convention for storing unsigned integers (see the later
-section entitled `Unsigned Integers' for more details). The primary HDU
-may also consist of only a header with a null array containing no
-data pixels.
-
-Any number of additional HDUs may follow the primary array; these
-additional HDUs are called FITS `extensions'.  There are currently 3
-types of extensions defined by the FITS standard:
-
-\begin{itemize}
-\item
-  Image Extension - a N-dimensional array of pixels, like in a primary array
-\item
-  ASCII Table Extension - rows and columns of data in ASCII character format
-\item
-  Binary Table Extension - rows and columns of data in binary representation
-\end{itemize}
-
-In each case the HDU consists of an ASCII Header Unit followed by an optional
-Data Unit.  For historical reasons, each Header or Data unit must be an
-exact multiple of 2880 8-bit bytes long.  Any unused space is padded
-with fill characters (ASCII blanks or zeros).
-
-Each Header Unit consists of any number of 80-character keyword records
-or `card images' which have the general form:
-
-\begin{verbatim}
-  KEYNAME = value / comment string
-  NULLKEY =       / comment: This keyword has no value
-\end{verbatim}
-The keyword names may be up to 8 characters long and can only contain
-uppercase letters, the digits 0-9, the hyphen, and the underscore
-character. The keyword name is (usually) followed by an equals sign and
-a space character (= ) in columns 9 - 10 of the record, followed by the
-value of the keyword which may be either an integer, a floating point
-number, a character string (enclosed in single quotes), or a boolean
-value (the letter T or F).   A keyword may also have a null or undefined
-value if there is no specified value string, as in the second example.
-
-The last keyword in the header is always the `END' keyword which has no
-value or comment fields. There are many rules governing the exact
-format of a keyword record (see the NOST FITS Standard) so it is better
-to rely on standard interface software like FITSIO to correctly
-construct or to parse the keyword records rather than try to deal
-directly with the raw FITS formats.
-
-Each Header Unit begins with a series of required keywords which depend
-on the type of HDU.  These required keywords specify the size and
-format of the following Data Unit.  The header may contain other
-optional keywords to describe other aspects of the data, such as the
-units or scaling values.  Other COMMENT or HISTORY keywords are also
-frequently added to further document the data file.
-
-The optional Data Unit immediately follows the last 2880-byte block in
-the Header Unit.  Some HDUs do not have a Data Unit and only consist of
-the Header Unit.
-
-If there is more than one HDU in the FITS file, then the Header Unit of
-the next HDU immediately follows the last 2880-byte block of the
-previous Data Unit (or Header Unit if there is no Data Unit).
-
-The main required keywords in FITS primary arrays or image extensions are:
-\begin{itemize}
-\item
-BITPIX -- defines the datatype of the array: 8, 16, 32, 64, -32, -64 for
-unsigned 8--bit byte, 16--bit signed integer, 32--bit signed integer,
-64--bit signed integer,
-32--bit IEEE floating point, and 64--bit IEEE double precision floating
-point, respectively.
-\item
-NAXIS --  the number of dimensions in the array, usually 0, 1, 2, 3, or 4.
-\item
-NAXISn -- (n ranges from 1 to NAXIS) defines the size of each dimension.
-\end{itemize}
-
-FITS tables start with the keyword XTENSION = `TABLE' (for ASCII
-tables) or XTENSION = `BINTABLE' (for binary tables) and have the
-following main keywords:
-\begin{itemize}
-\item
-TFIELDS -- number of fields or columns in the table
-\item
-NAXIS2 -- number of rows in the table
-\item
-TTYPEn -- for each column (n ranges from 1 to TFIELDS) gives the
-name of the column
-\item
-TFORMn -- the datatype of the column
-\item
-TUNITn -- the physical units of the column (optional)
-\end{itemize}

-\chapter{FITSIO Conventions and Guidelines }
-
-
-\section{CFITSIO Size Limitations}
-
-CFITSIO places few restrictions on the size of FITS files that it
-reads or writes.  There are a few limits, however, which may affect
-some extreme cases:
-
-1.  The maximum number of FITS files that may be simultaneously opened
-by CFITSIO is set by NMAXFILES as defined in fitsio2.h.  It is currently
-set = 300 by default.  CFITSIO will allocate about 80 * NMAXFILES bytes
-of memory for internal use.  Note that the underlying C compiler or
-operating system, may have a smaller limit on the number of opened files.
-The C symbolic constant FOPEN\_MAX is intended to define the maximum
-number of files that may open at once (including any other text or
-binary files that may be open, not just FITS files).  On some systems it
-has been found that gcc supports a maximum of 255 opened files.
-
-2.  By default, CFITSIO can handle FITS files up to 2.1 GB in size (2**31
-bytes).  This file size limit is often imposed by 32-bit operating
-systems.  More recently, as 64-bit operating systems become more common, an
-industry-wide standard (at least on Unix systems) has been developed to
-support larger sized files (see http://ftp.sas.com/standards/large.file/).
-Starting with version 2.1 of CFITSIO, larger FITS files up to 6 terabytes
-in size may be read and written on supported platforms.  In order
-to support these larger files, CFITSIO must be compiled with the
-'-D\_LARGEFILE\_SOURCE' and `-D\_FILE\_OFFSET\_BITS=64' compiler flags.
-Some platforms may also require the `-D\_LARGE\_FILES' compiler flag.
- This causes the compiler to allocate 8-bytes instead of
-4-bytes for the `off\_t' datatype which is used to store file offset
-positions.  It appears that in most cases it is not necessary to
-also include these compiler flags when compiling programs that link to
-the CFITSIO library.
-
-If CFITSIO is compiled with the -D\_LARGEFILE\_SOURCE
-and -D\_FILE\_OFFSET\_BITS=64 flags on a
-platform that supports large files, then it can read and write FITS
-files that contain up to 2**31 2880-byte FITS records, or approximately
-6 terabytes in size.  It is still required that the value of the NAXISn
-and PCOUNT keywords in each extension be within the range of a signed
-4-byte integer (max value = 2,147,483,648).  Thus, each dimension of an
-image (given by the NAXISn keywords), the total width of a table
-(NAXIS1 keyword), the number of rows in a table (NAXIS2 keyword), and
-the total size of the variable-length array heap in binary tables
-(PCOUNT keyword) must be less than this limit.
-
-Currently, support for large files within CFITSIO has been tested
-on the Linux, Solaris, and IBM AIX operating systems.
-
-
-\section{Multiple Access to the Same FITS File}
-
-CFITSIO supports simultaneous read and write access to multiple HDUs in
-the same FITS file.  Thus, one can open the same FITS file twice within
-a single program and move to 2 different HDUs in the file, and then
-read and write data or keywords to the 2 extensions just as if one were
-accessing 2 completely separate FITS files.   Since in general it is
-not possible to physically open the same file twice and then expect to
-be able to simultaneously (or in alternating succession) write to 2
-different locations in the file, CFITSIO recognizes when the file to be
-opened (in the call to fits\_open\_file) has already been opened and
-instead of actually opening the file again, just logically links the
-new file to the old file.  (This only applies if the file is opened
-more than once within the same program, and does not prevent the same
-file from being simultaneously opened by more than one program).  Then
-before CFITSIO reads or writes to either (logical) file, it makes sure
-that any modifications made to the other file have been completely
-flushed from the internal buffers to the file.  Thus, in principle, one
-could open a file twice, in one case pointing to the first extension
-and in the other pointing to the 2nd extension and then write data to
-both extensions, in any order, without danger of corrupting the file,
-There may be some efficiency penalties in doing this however, since
-CFITSIO has to flush all the internal buffers related to one file
-before switching to the  other, so it would still be prudent to
-minimize the number of times one switches back and forth between doing
-I/O to different HDUs in the same file.
-
-
-\section{Current Header Data Unit (CHDU)}
-
-In general, a FITS file can contain multiple Header Data Units, also
-called extensions.  CFITSIO only operates within one HDU at any given
-time, and the currently selected HDU is called the Current Header Data
-Unit (CHDU).  When a FITS file is first created or opened the CHDU is
-automatically defined to be the first HDU (i.e., the primary array).
-CFITSIO routines are provided to move to and open any other existing
-HDU within the FITS file or to append or insert a new HDU in the FITS
-file which then becomes the CHDU.
-
-
-\section{Subroutine Names}
-
-All FITSIO subroutine names begin with the letters 'ft' to distinguish
-them from other subroutines and are 5 or 6 characters long. Users should
-not name their own subroutines beginning with 'ft' to avoid conflicts.
-(The SPP interface routines all begin with 'fs'). Subroutines which read
-or get information from the FITS file have names beginning with
-'ftg...'. Subroutines which write or put information into the FITS file
-have names beginning with 'ftp...'.
-
-
-\section{Subroutine Families and Datatypes}
-
-Many of the subroutines come in families which differ only in the
-datatype of the associated parameter(s) .  The datatype of these
-subroutines is indicated by the last letter of the subroutine name
-(e.g., 'j' in 'ftpkyj') as follows:
-
-\begin{verbatim}
-        x - bit
-        b - character*1 (unsigned byte)
-        i - short integer (I*2)
-        j - integer (I*4, 32-bit integer)
-        k - long long integer (I*8, 64-bit integer)
-        e - real exponential floating point (R*4)
-        f - real fixed-format floating point (R*4)
-        d - double precision real floating-point (R*8)
-        g - double precision fixed-format floating point (R*8)
-        c - complex reals (pairs of R*4 values)
-        m - double precision complex (pairs of R*8 values)
-        l - logical (L*4)
-        s - character string
-\end{verbatim}
-
-When dealing with the FITS byte datatype, it is important to remember
-that the raw values (before any scaling by the BSCALE and BZERO, or
-TSCALn and TZEROn keyword values) in byte arrays (BITPIX = 8) or byte
-columns (TFORMn = 'B') are interpreted as unsigned bytes with values
-ranging from 0 to 255. Some Fortran compilers support a non-standard
-byte datatype such as INTEGER*1, LOGICAL*1, or BYTE, which can sometimes
-be used instead of CHARACTER*1 variables. Many machines permit passing a
-numeric datatype (such as INTEGER*1) to the FITSIO subroutines which are
-expecting a CHARACTER*1 datatype, but this technically violates the
-Fortran-77 standard and is not supported on all machines (e.g., on a VAX/VMS
-machine one must use the VAX-specific \%DESCR function).
-
-One feature of the CFITSIO routines is that they can operate on a `X'
-(bit) column in a binary table as though it were a `B' (byte) column.
-For example a `11X' datatype column can be interpreted the same as a
-`2B' column (i.e., 2 unsigned 8-bit bytes).  In some instances, it can
-be more efficient to read and write whole bytes at a time, rather than
-reading or writing each individual bit.
-
-The double precision complex datatype is not a standard Fortran-77
-datatype.  If a particular Fortran compiler does not directly support
-this datatype,  then one may instead pass an array of pairs of double
-precision values to these subroutines.  The first  value in each pair
-is the real part, and the second is the imaginary part.
-
-
-\section{Implicit Data Type Conversion}
-
-The FITSIO routines that read and write numerical data can perform
-implicit data type conversion.  This means that the data type of the
-variable or array in the program does not need to be the same as the
-data type of the value in the FITS file.  Data type conversion is
-supported for numerical and string data types (if the string contains a
-valid number enclosed in quotes) when reading a FITS header keyword
-value and for numeric values when reading or writing values in the
-primary array or a table column.  CFITSIO returns status =
-NUM\_OVERFLOW  if the converted data value exceeds the range of the
-output data type.  Implicit data type conversion is not supported
-within binary tables for string, logical, complex, or double complex
-data types.
-
-In addition, any table column may be read as if it contained string values.
-In the case of numeric columns the returned string will be formatted
-using the TDISPn display format if it exists.
-
-
-\section{Data Scaling}
-
-When reading numerical data values in the primary array or a
-table column, the values will be scaled automatically by the BSCALE and
-BZERO (or TSCALn and TZEROn) header keyword values if they are
-present in the header.  The scaled data that is returned to the reading
-program will have
-
-\begin{verbatim}
-        output value = (FITS value) * BSCALE + BZERO
-\end{verbatim}
-(a corresponding formula using TSCALn and TZEROn is used when reading
-from table columns).  In the case of integer output values the floating
-point scaled value is truncated to an integer (not rounded to the
-nearest integer).  The ftpscl and fttscl subroutines may be used to
-override the scaling parameters defined in the header (e.g., to turn
-off the scaling so that the program can read the raw unscaled values
-from the FITS file).
-
-When writing numerical data to the primary array or to a table
-column the data values will generally be automatically inversely scaled
-by the value of the BSCALE and BZERO (or TSCALn and TZEROn) header
-keyword values if they they exist in the header.  These keywords must
-have been written to the header before any data is written for them to
-have any effect.  Otherwise, one may use the ftpscl and fttscl
-subroutines to define or override the scaling keywords in the header
-(e.g., to turn off the scaling so that the program can write the raw
-unscaled values into the FITS file). If scaling is performed, the
-inverse scaled output value that is written into the FITS file will
-have
-
-\begin{verbatim}
-         FITS value = ((input value) - BZERO) / BSCALE
-\end{verbatim}
-(a corresponding formula using TSCALn and TZEROn is used when
-writing to table columns).  Rounding to the nearest integer, rather
-than truncation, is performed when writing integer datatypes to the
-FITS file.
-
-
-\section{Error Status Values and the Error Message Stack}
-
-The last parameter in nearly every FITSIO subroutine is the error
-status value which is both an input and an output parameter.  A
-returned positive value for this parameter indicates an error was
-detected.  A listing of all the FITSIO status code values is given at
-the end of this document.
-
-The FITSIO library uses an `inherited status' convention for the status
-parameter which means that if a subroutine is called with a positive
-input value of the status parameter, then the subroutine will exit
-immediately without changing the value of the status parameter.  Thus,
-if one passes the status value returned from each FITSIO routine as
-input to the next FITSIO subroutine, then whenever an error is detected
-all further FITSIO processing will cease.  This convention can simplify
-the error checking in application programs because it is not necessary
-to check the value of the status parameter after every single FITSIO
-subroutine call.  If a program contains a sequence of several FITSIO
-calls, one can just check the status value after the last call.  Since
-the returned status values are generally distinctive, it should be
-possible to determine which subroutine originally returned the error
-status.
-
-FITSIO also maintains an internal stack of error messages (80-character
-maximum length) which in many cases provide a more detailed explanation
-of the cause of the error than is provided by the error status number
-alone. It is recommended that the error message stack be printed out
-whenever a program detects a FITSIO error. To do this, call the FTGMSG
-routine repeatedly to get the successive messages on the stack. When the
-stack is empty FTGMSG will return a blank string. Note that this is a
-`First In -- First Out' stack, so the oldest error message is returned
-first by ftgmsg.
-
-
-\section{Variable-Length Array Facility in Binary Tables}
-
-FITSIO provides easy-to-use support for reading and writing data in
-variable length fields of a binary table. The variable length columns
-have TFORMn keyword values of the form `1Pt(len)' or `1Qt(len)' where `t' is the
-datatype code (e.g., I, J, E, D, etc.) and `len' is an integer
-specifying the maximum length of the vector in the table.  If the value
-of `len' is not specified when the table is created (e.g., if the TFORM
-keyword value is simply specified as '1PE' instead of '1PE(400) ), then
-FITSIO will automatically scan the table when it is closed to
-determine the maximum length of the vector and will append this value
-to the TFORMn value.
-
-The same routines which read and write data in an ordinary fixed length
-binary table extension are also used for variable length fields,
-however, the subroutine parameters take on a slightly different
-interpretation as described below.
-
-All the data in a variable length field is written into an area called
-the `heap' which follows the main fixed-length FITS binary table.  The
-size of the heap, in bytes, is specified with the PCOUNT keyword in the
-FITS header.  When creating a new binary table, the initial value of
-PCOUNT should usually be set to zero.  FITSIO will recompute the size
-of the heap as the data is written and will automatically update the
-PCOUNT keyword value when the table is closed.  When writing variable
-length data to a table, CFITSIO will automatically extend the size
-of the heap area if necessary, so that any following HDUs do not
-get overwritten.
-
-By default the heap data area starts immediately after the last row of
-the fixed-length table.  This default starting location may be
-overridden by the THEAP keyword, but this is not recommended.
-If additional rows of data are added to the table, CFITSIO will
-automatically shift the the heap down to make room for the new
-rows, but it is obviously be more efficient to initially
-create the table with the necessary number of blank rows, so that
-the heap does not needed to be constantly moved.
-
-When writing to a variable length field, the entire array of values for
-a given row of the table must be written with a single call to FTPCLx.
-The total length of the array is calculated from (NELEM+FELEM-1). One
-cannot append more elements to an existing field at a later time; any
-attempt to do so will simply overwrite all the data which was previously
-written. Note also that the new data will be written to a new area of
-the heap and the heap space used by the previous write cannot be
-reclaimed. For this reason it is advised that each row of a variable
-length field only be written once. An exception to this general rule
-occurs when setting elements of an array as undefined. One must first
-write a dummy value into the array with FTPCLx, and then call FTPCLU to
-flag the desired elements as undefined. (Do not use the FTPCNx family
-of routines with variable length fields). Note that the rows of a table,
-whether fixed or variable length, do not have to be written
-consecutively and may be written in any order.
-
-When writing to a variable length ASCII character field (e.g., TFORM =
-'1PA') only a single character string written.  FTPCLS writes the whole
-length of the input string (minus any trailing blank characters), thus
-the NELEM and FELEM parameters are ignored.  If the input string is
-completely blank then FITSIO will write one blank character to the FITS
-file.  Similarly, FTGCVS and FTGCFS read the entire string (truncated
-to the width of the character string argument in the subroutine call)
-and also ignore the NELEM and FELEM parameters.
-
-The FTPDES subroutine is useful in situations where multiple rows of a
-variable length column have the identical array of values.  One can
-simply write the array once for the first row, and then use FTPDES to
-write the same descriptor values into the other rows (use the FTGDES
-routine to read the first descriptor value);  all the rows will then
-point to the same storage location thus saving disk space.
-
-When reading from a variable length array field one can only read as
-many elements as actually exist in that row of the table; reading does
-not automatically continue with the next row of the table as occurs
-when reading an ordinary fixed length table field.  Attempts to read
-more than this will cause an error status to be returned.  One can
-determine the number of elements in each row of a variable column with
-the FTGDES subroutine.
-
-
-\section{Support for IEEE Special Values}
-
-The ANSI/IEEE-754 floating-point number standard defines certain
-special values that are used to represent such quantities as
-Not-a-Number (NaN), denormalized, underflow, overflow, and infinity.
-(See the Appendix in the NOST FITS standard or the NOST FITS User's
-Guide for a list of these values).  The FITSIO subroutines that read
-floating point data in FITS files recognize these IEEE special values
-and by default interpret the overflow and infinity values as being
-equivalent to a NaN, and convert the underflow and denormalized values
-into zeros.  In some cases programmers may want access to the raw IEEE
-values, without any modification by FITSIO.  This can be done by
-calling the FTGPVx or FTGCVx routines while specifying 0.0 as the value
-of the NULLVAL parameter.  This will force FITSIO to simply pass the
-IEEE values through to the application program, without any
-modification.  This does not work for double precision values on
-VAX/VMS machines, however, where there is no easy way to bypass the
-default interpretation of the IEEE special values. This is also not
-supported when reading floating-point images that have been compressed
-with the FITS tiled image compression convention that is discussed in
-section 5.6;  the pixels values in tile compressed images are
-represented by scaled integers, and a reserved integer value
-(not a NaN) is used to represent undefined pixels.
-
-
-
-\section{When the Final Size of the FITS HDU is Unknown}
-
-It is not required to know the total size of a FITS data array or table
-before beginning to write the data to the FITS file.  In the case of
-the primary array or an image extension, one should initially create
-the array with the size of the highest dimension (largest NAXISn
-keyword) set to a dummy value, such as 1.  Then after all the data have
-been written and the true dimensions are known, then the NAXISn value
-should be updated using the fits\_ update\_key routine before moving to
-another extension or closing the FITS file.
-
-When writing to FITS tables, CFITSIO automatically keeps track of the
-highest row number that is written to, and will increase the size of
-the table if necessary.  CFITSIO will also automatically insert space
-in the FITS file if necessary, to ensure that the data 'heap', if it
-exists, and/or any additional HDUs that follow the table do not get
-overwritten as new rows are written to the table.
-
-As a general rule it is best to specify the initial number of rows = 0
-when the table is created, then let CFITSIO keep track of the number of
-rows that are actually written.  The application program should not
-manually update the number of rows in the table (as given by the NAXIS2
-keyword) since CFITSIO does this automatically.  If a table is
-initially created with more than zero rows, then this will usually be
-considered as the minimum size of the table, even if fewer rows are
-actually written to the table.  Thus, if a table is initially created
-with NAXIS2 = 20, and CFITSIO only writes 10 rows of data before
-closing the table, then NAXIS2 will remain equal to 20.  If however, 30
-rows of data are written to this table, then NAXIS2 will be increased
-from 20 to 30.  The one exception to this automatic updating of the
-NAXIS2 keyword is if the application program directly modifies the
-value of NAXIS2 (up or down) itself just before closing the table.  In this
-case, CFITSIO does not update NAXIS2 again, since it assumes that the
-application program must have had a good reason for changing the value
-directly.  This is not recommended, however, and is only provided for
-backward compatibility with software that initially creates a table
-with a large number of rows, than decreases the NAXIS2 value to the
-actual smaller value just before closing the table.
-
-
-\section{Local FITS Conventions supported by FITSIO}
-
-CFITSIO supports several local FITS conventions which are not
-defined in the official NOST FITS standard and which are not
-necessarily recognized or supported by other FITS software packages.
-Programmers should be cautious about using these features, especially
-if the FITS files that are produced are expected to be processed by
-other software systems which do not use the CFITSIO interface.
-
-
-\subsection{Support for Long String Keyword Values.}
-
-The length of a standard FITS string keyword is limited to 68
-characters because it must fit entirely within a single FITS header
-keyword record.  In some instances it is necessary to encode strings
-longer than this limit, so FITSIO supports a local convention in which
-the string value is continued over multiple keywords. This
-continuation convention uses an ampersand character at the end of each
-substring to indicate that it is continued on the next keyword, and the
-continuation keywords all have the name CONTINUE without an equal sign
-in column 9. The string value may be continued in this way over as many
-additional CONTINUE keywords as is required.  The following lines
-illustrate this continuation convention which is used in the value of
-the STRKEY keyword:
-
-\begin{verbatim}
-LONGSTRN= 'OGIP 1.0'           / The OGIP Long String Convention may be used.
-STRKEY  = 'This is a very long string keyword&'  / Optional Comment
-CONTINUE  ' value that is continued over 3 keywords in the &  '
-CONTINUE  'FITS header.' / This is another optional comment.
-\end{verbatim}
-It is recommended that the LONGSTRN keyword, as shown
-here, always be included in any HDU that uses this longstring
-convention.  A subroutine called FTPLSW
-has been provided in CFITSIO to write this keyword if it does not
-already exist.
-
-This long string convention is supported by the following FITSIO
-subroutines that deal with string-valued keywords:
-
-\begin{verbatim}
-      ftgkys - read a string keyword
-      ftpkls - write (append) a string keyword
-      ftikls - insert a string keyword
-      ftmkls - modify the value of an existing string keyword
-      ftukls - update an existing keyword, or write a new keyword
-      ftdkey - delete a keyword
-\end{verbatim}
-These routines will transparently read, write, or delete a long string
-value in the FITS file, so programmers in general do not have to be
-concerned about the details of the convention that is used to encode
-the long string in the FITS header.  When reading a long string, one
-must ensure that the character string parameter used in these
-subroutine calls has been declared long enough to hold the entire
-string, otherwise the returned string value will be truncated.
-
-Note that the more commonly used FITSIO subroutine to write string
-valued keywords (FTPKYS) does NOT support this long string convention
-and only supports strings up to 68 characters in length.  This has been
-done deliberately to prevent programs from inadvertently writing
-keywords using this non-standard convention without the explicit intent
-of the programmer or user.   The FTPKLS subroutine must be called
-instead to write long strings.  This routine can also be used to write
-ordinary string values less than 68 characters in length.
-
-
-\subsection{Arrays of Fixed-Length Strings in Binary Tables}
-
-CFITSIO supports 2 ways to specify that a character column in a binary
-table contains an array of fixed-length strings.  The first way, which
-is officially supported by the FITS Standard document, uses the TDIMn keyword.
-For example, if TFORMn = '60A' and TDIMn = '(12,5)' then that
-column will be interpreted as containing an array of 5 strings, each 12
-characters long.
-
-FITSIO also supports a
-local convention for the format of the TFORMn keyword value of the form
-'rAw' where 'r' is an integer specifying the total width in characters
-of the column, and 'w' is an integer specifying the (fixed) length of
-an individual unit string within the vector.  For example, TFORM1 =
-'120A10' would indicate that the binary table column is 120 characters
-wide and consists of 12 10-character length strings.  This convention
-is recognized by the FITSIO subroutines that read or write strings in
-binary tables.   The Binary Table definition document specifies that
-other optional characters may follow the datatype code in the TFORM
-keyword, so this local convention is in compliance with the
-FITS standard, although other FITS readers are not required to
-recognize this convention.
-
-The Binary Table definition document that was approved by the IAU in
-1994 contains an appendix describing an alternate convention for
-specifying arrays of fixed or variable length strings in a binary table
-character column (with the form 'rA:SSTRw/nnn)'.  This appendix was not
-officially voted on by the IAU and hence is still provisional.  FITSIO
-does not currently support this proposal.
-
-
-\subsection{Keyword Units Strings}
-
-One deficiency of the current FITS Standard is that it does not define
-a specific convention for recording the physical units of a keyword
-value.  The TUNITn keyword can be used to specify the physical units of
-the values in a table column, but there is no analogous convention for
-keyword values.  The comment field of the keyword is often used for
-this purpose, but the units are usually not specified in a well defined
-format that FITS readers can easily recognize and extract.
-
-To solve this deficiency, FITSIO uses a local convention in which the
-keyword units are enclosed in square brackets as the first token in the
-keyword comment field; more specifically, the opening square bracket
-immediately follows the slash '/' comment field delimiter and a single
-space character.  The following examples illustrate keywords that use
-this convention:
-
-
-\begin{verbatim}
-EXPOSURE=               1800.0 / [s] elapsed exposure time
-V_HELIO =                16.23 / [km s**(-1)] heliocentric velocity
-LAMBDA  =                5400. / [angstrom] central wavelength
-FLUX    = 4.9033487787637465E-30 / [J/cm**2/s] average flux
-\end{verbatim}
-
-In general, the units named in the IAU(1988) Style Guide are
-recommended, with the main exception that the preferred unit for angle
-is 'deg' for degrees.
-
-The FTPUNT and FTGUNT subroutines in FITSIO write and read,
-respectively, the keyword unit strings in an existing keyword.
-
-
-\subsection{HIERARCH Convention for Extended Keyword Names}
-
-CFITSIO supports the HIERARCH keyword convention which allows keyword
-names that are longer then 8 characters and may contain the full range
-of printable ASCII text characters.  This convention
-was developed at the European Southern Observatory (ESO)  to support
-hierarchical FITS keyword such as:
-
-\begin{verbatim}
-HIERARCH ESO INS FOCU POS = -0.00002500 / Focus position
-\end{verbatim}
-Basically, this convention uses the FITS keyword 'HIERARCH' to indicate
-that this convention is being used, then the actual keyword name
-({\tt'ESO INS FOCU POS'} in this example) begins in column 10 and can
-contain any printable ASCII text characters, including spaces.  The
-equals sign marks the end of the keyword name and is followed by the
-usual value and comment fields just as in standard FITS keywords.
-Further details of this convention are described at
-http://arcdev.hq.eso.org/dicb/dicd/dic-1-1.4.html (search for
-HIERARCH).
-
-This convention allows a much broader range of keyword names
-than is allowed by the FITS Standard.  Here are more examples
-of such keywords:
-
-\begin{verbatim}
-HIERARCH LongKeyword = 47.5 / Keyword has > 8 characters, and mixed case
-HIERARCH XTE$TEMP = 98.6 / Keyword contains the '$' character
-HIERARCH Earth is a star = F / Keyword contains embedded spaces
-\end{verbatim}
-CFITSIO will transparently read and write these keywords, so application
-programs do not in general need to know anything about the specific
-implementation details of the HIERARCH convention.  In particular,
-application programs do not need to specify the `HIERARCH' part of the
-keyword name when reading or writing keywords (although it
-may be included if desired).  When writing a keyword, CFITSIO first
-checks to see if the keyword name is legal as a standard FITS keyword
-(no more than 8 characters long and containing only letters, digits, or
-a minus sign or underscore). If so it writes it as a standard FITS
-keyword, otherwise it uses the hierarch convention to write the
-keyword.   The maximum keyword name length is 67 characters, which
-leaves only 1 space for the value field.  A more practical limit is
-about 40 characters, which leaves enough room for most keyword values.
-CFITSIO returns an error if there is not enough room for both the
-keyword name and the keyword value on the 80-character card, except for
-string-valued keywords which are simply truncated so that the closing
-quote character falls in column 80.  In the current implementation,
-CFITSIO preserves the case of the letters when writing the keyword
-name, but it is case-insensitive when reading or searching for a
-keyword.  The current implementation allows any ASCII text character
-(ASCII 32 to ASCII 126) in the keyword name except for the '='
-character.  A space is also required on either side of the equal sign.
-
-
-\section{Optimizing Code for Maximum Processing Speed}
-
-CFITSIO has been carefully designed to obtain the highest possible
-speed when reading and writing FITS files.  In order to achieve the
-best performance, however, application programmers must be careful to
-call the CFITSIO routines appropriately and in an efficient sequence;
-inappropriate usage of CFITSIO routines can greatly slow down the
-execution speed of a program.
-
-The maximum possible I/O speed of CFITSIO depends of course on the type
-of computer system that it is running on.  As a rough guide, the
-current generation of workstations can achieve speeds of 2 -- 10 MB/s
-when reading or writing FITS images and similar, or slightly slower
-speeds with FITS binary tables.  Reading of FITS files can occur at
-even higher rates (30MB/s or more) if the FITS file is still cached in
-system memory following a previous read or write operation on the same
-file.  To more accurately predict the best performance that is possible
-on any particular system, a diagnostic program called ``speed.c'' is
-included with the CFITSIO distribution which can be run to
-approximately measure the maximum possible speed of writing and reading
-a test FITS file.
-
-The following 2 sections provide some background on how CFITSIO
-internally manages the data I/O and describes some strategies that may
-be used to optimize the processing speed of software that uses
-CFITSIO.
-
-
-\subsection{Background Information: How CFITSIO Manages Data I/O}
-
-Many CFITSIO operations involve transferring only a small number of
-bytes to or from the FITS file (e.g, reading a keyword, or writing a
-row in a table); it would be very inefficient to physically read or
-write such small blocks of data directly in the FITS file on disk,
-therefore CFITSIO maintains a set of internal Input--Output (IO)
-buffers in RAM memory that each contain one FITS block (2880 bytes) of
-data.  Whenever CFITSIO needs to access data in the FITS file, it first
-transfers the FITS block containing those bytes into one of the IO
-buffers in memory.  The next time CFITSIO needs to access bytes in the
-same block it can then go to the fast IO buffer rather than using a
-much slower system disk access routine.  The number of available IO
-buffers is determined by the NIOBUF parameter (in fitsio2.h) and is
-currently set to 40.
-
-Whenever CFITSIO reads or writes data it first checks to see if that
-block of the FITS file is already loaded into one of the IO buffers.
-If not, and if there is an empty IO buffer available, then it will load
-that block into the IO buffer (when reading a FITS file) or will
-initialize a new block (when writing to a FITS file).  If all the IO
-buffers are already full, it must decide which one to reuse (generally
-the one that has been accessed least recently), and flush the contents
-back to disk if it has been modified before loading the new block.
-
-The one major exception to the above process occurs whenever a large
-contiguous set of bytes are accessed, as might occur when reading or
-writing a FITS image.  In this case CFITSIO bypasses the internal IO
-buffers and simply reads or writes the desired bytes directly in the
-disk file with a single call to a low-level file read or write
-routine.  The minimum threshold for the number of bytes to read or
-write this way is set by the MINDIRECT parameter and is currently set
-to 3 FITS blocks = 8640 bytes.  This is the most efficient way to read
-or write large chunks of data and can achieve IO transfer rates of
-5 -- 10MB/s or greater.  Note that this fast direct IO process is not
-applicable when accessing columns of data in a FITS table because the
-bytes are generally not contiguous since they are interleaved by the
-other columns of data in the table.  This explains why the speed for
-accessing FITS tables is generally slower than accessing
-FITS images.
-
-Given this background information, the general strategy for efficiently
-accessing FITS files should now be apparent:  when dealing with FITS
-images, read or write large chunks of data at a time so that the direct
-IO mechanism will be invoked;  when accessing FITS headers or FITS
-tables, on the other hand, once a particular FITS block has been
-loading into one of the IO buffers, try to access all the needed
-information in that block before it gets flushed out of the IO buffer.
-It is important to avoid the situation where the same FITS block is
-being read then flushed from a IO buffer multiple times.
-
-The following section gives more specific suggestions for optimizing
-the use of CFITSIO.
-
-
-\subsection{Optimization Strategies}
-
-1.  Because the data in FITS files is always stored in "big-endian" byte order,
-where the first byte of numeric values contains the most significant bits and the
-last byte contains the least significant bits, CFITSIO must swap the order of the bytes
-when reading or writing FITS files when running on little-endian machines (e.g.,
-Linux and Microsoft Windows operating systems running on PCs with x86 CPUs).
-
-On fairly new CPUs that support "SSSE3" machine instructions
-(e.g., starting with Intel Core 2 CPUs in 2007, and in AMD CPUs
-beginning in 2011) significantly faster 4-byte and 8-byte swapping
-algorithms are available. These faster byte swapping functions are
-not used by default in CFITSIO (because of the potential code
-portablility issues), but users can enable them on supported
-platforms by adding the appropriate compiler flags (-mssse3 with gcc
-or icc on linux) when compiling the swapproc.c source file, which will
-allow the compiler to generate code using the SSSE3 instruction set.
-A convenient way to do this is to configure the CFITSIO library
-with the following command:
-
-\begin{verbatim}
-  >  ./configure --enable-ssse3
-\end{verbatim}
-Note, however, that a binary executable file that is
-created using these faster functions will only run on
-machines that support the SSSE3 machine instructions. It will
-crash on machines that do not support them.
-
-For faster 2-byte swaps on virtually all x86-64 CPUs (even those that
-do not support SSSE3), a variant using only SSE2 instructions exists.
-SSE2 is enabled by default on x86\_64 CPUs with 64-bit operating systems
-(and is also automatically enabled by the --enable-ssse3 flag).
-When running on x86\_64 CPUs with 32-bit operating systems, these faster
-2-byte swapping algorithms are not used by default in CFITSIO, but can be
-enabled explicitly with:
-
-\begin{verbatim}
-./configure --enable-sse2
-\end{verbatim}
-Preliminary testing indicates that these SSSE3 and SSE2 based
-byte-swapping algorithms can boost the CFITSIO performance when
-reading or writing FITS images by 20\% - 30\% or more.
-It is important to note, however, that compiler optimization must be
-turned on (e.g., by using the -O1 or -O2 flags in gcc) when building
-programs that use these fast byte-swapping algorithms in order
-to reap the full benefit of the SSSE3 and SSE2 instructions; without
-optimization, the code may actually run slower than when using
-more traditional byte-swapping techniques.
-
-2.  When dealing with a FITS primary array or IMAGE extension, it is
-more efficient to read or write large chunks of the  image at a time
-(at least 3 FITS blocks = 8640 bytes) so that the direct IO mechanism
-will be used as described in the previous section.  Smaller chunks of
-data are read or written via the IO buffers, which is somewhat less
-efficient because of the extra copy operation and additional
-bookkeeping steps that are required.  In principle it is more efficient
-to read or write as big an array of image pixels at one time as
-possible, however, if the array becomes so large that the operating
-system cannot store it all in RAM, then the performance may be degraded
-because of the increased swapping of virtual memory to disk.
-
-3.  When dealing with FITS tables, the most important efficiency factor
-in the software design is to read or write the data in the FITS file in
-a single pass through the file.  An example of poor program design
-would be to read a large, 3-column table by sequentially reading the
-entire first column, then going back to read the 2nd column, and
-finally the 3rd column; this obviously requires 3 passes through the
-file which could triple the execution time of an I/O limited program.
-For small tables this is not important, but when reading multi-megabyte
-sized tables these inefficiencies can become significant.  The more
-efficient procedure in this case is to read or write only as many rows
-of the table as will fit into the available internal I/O buffers, then
-access all the necessary columns of data within that range of rows.
-Then after the program is completely finished with the data in those
-rows it can move on to the next range of rows that will fit in the
-buffers, continuing in this way until the entire file has been
-processed.  By using this procedure of accessing all the columns of a
-table in parallel rather than sequentially, each block of the FITS file
-will only be read or written once.
-
-The optimal number of rows to read or write at one time in a given
-table depends on the width of the table row, on the number of I/O
-buffers that have been allocated in FITSIO, and also on the number of
-other FITS files that are open at the same time (since one I/O buffer
-is always reserved for each open FITS file).  Fortunately, a FITSIO
-routine is available that will return the optimal number of rows for a
-given table:  call ftgrsz(unit, nrows, status).  It is not critical to
-use exactly the value of nrows returned by this routine, as long as one
-does not exceed it.  Using a very small value however can also lead to
-poor performance because of the overhead from the larger number of
-subroutine calls.
-
-The optimal number of rows returned by ftgrsz is valid only as long as
-the application program is only reading or writing data in the
-specified table.  Any other calls to access data in the table header
-would  cause additional blocks of data to be
-loaded into the I/O buffers displacing data from the original table,
-and should be avoided during the critical period while the table is
-being read or written.
-
-4.  Use binary table extensions rather than ASCII table
-extensions for better efficiency  when dealing with tabular data.  The
-I/O to ASCII tables is slower because of the overhead in formatting or
-parsing the ASCII data fields, and because ASCII tables are about twice
-as large as binary tables with the same information content.
-
-5. Design software so that it reads the FITS header keywords in the
-same order in which they occur in the file.  When reading keywords,
-FITSIO searches forward starting from the position of the last keyword
-that was read.  If it reaches the end of the header without finding the
-keyword, it then goes back to the start of the header and continues the
-search down to the position where it started.  In practice, as long as
-the entire FITS header can fit at one time in the available internal I/O
-buffers, then the header keyword access will be very fast and it makes
-little difference which order they are accessed.
-
-6. Avoid the use of scaling (by using the BSCALE and BZERO or TSCAL and
-TZERO keywords) in FITS files since the scaling operations add to the
-processing time needed to read or write the data.  In some cases it may
-be more efficient to temporarily turn off the scaling (using ftpscl or
-fttscl) and then read or write the raw unscaled values in the FITS
-file.
-
-7. Avoid using the 'implicit datatype conversion' capability in
-FITSIO.  For instance, when reading a FITS image with BITPIX = -32
-(32-bit floating point pixels), read the data into a single precision
-floating point data array in the program.  Forcing FITSIO to convert
-the data to a different datatype can significantly slow the program.
-
-8. Where feasible, design FITS binary tables using vector column
-elements so that the data are written as a contiguous set of bytes,
-rather than as single elements in multiple rows.  For example, it is
-faster to access the data in a table that contains a single row
-and 2 columns with TFORM keywords equal to  '10000E' and '10000J', than
-it is to access the same amount of data in a table with 10000 rows
-which has columns with the TFORM keywords equal to '1E' and '1J'.  In
-the former case the 10000 floating point values in the first column are
-all written in a contiguous block of the file which can be read or
-written quickly, whereas in the second case each floating point value
-in the first column is interleaved with the integer value in the second
-column of the same row so CFITSIO has to explicitly move to the
-position of each element to be read or written.
-
-9. Avoid the use of variable length vector columns in binary tables,
-since any reading or writing of these data requires that CFITSIO first
-look up or compute the starting address of each row of data in the
-heap.  In practice, this is probably not a significant efficiency issue.
-
-10. When copying data from one FITS table to another, it is faster to
-transfer the raw bytes instead of reading then writing each column of
-the table.  The FITSIO subroutines FTGTBS and FTPTBS (for ASCII
-tables), and  FTGTBB and FTPTBB (for binary tables) will perform
-low-level reads or writes of any contiguous range of bytes in a table
-extension.  These routines can be used to read or write a whole row (or
-multiple rows) of a table with a single subroutine call.   These
-routines are fast because they bypass all the usual data scaling, error
-checking and machine dependent data conversion that is normally done by
-FITSIO, and they allow the program to write the data to the output file
-in exactly the same byte order.  For these same reasons, use of these
-routines can be somewhat risky because no validation or machine
-dependent conversion is performed by these routines.  In general these
-routines are only recommended for optimizing critical pieces of code
-and should only be used by programmers who thoroughly understand the
-internal byte structure of the FITS tables they are reading or
-writing.
-
-11. Another strategy for improving the speed of writing a FITS table,
-similar to the previous one, is to directly construct the entire byte
-stream for a whole table row (or multiple rows) within the application
-program and then write it to the FITS file with
-ftptbb.  This avoids all the overhead normally present
-in the column-oriented CFITSIO write routines.  This technique should
-only be used for critical applications, because it makes the code more
-difficult to understand and maintain, and it makes the code more system
-dependent (e.g., do the bytes need to be swapped before writing to the
-FITS file?).
-
-12.  Finally, external factors such as the type of magnetic disk
-controller (SCSI or IDE), the size of the disk cache, the average seek
-speed of the disk, the amount of disk fragmentation, and the amount of
-RAM available on the system can all have a significant impact on
-overall I/O efficiency.  For critical applications, a system
-administrator should review the proposed system hardware to identify any
-potential I/O bottlenecks.

-\chapter{  Basic Interface Routines }
-
-This section defines a basic set of subroutines that can be
-used to perform the most common types of read and write operations
-on FITS files.  New users should start with these subroutines and
-then, as needed, explore the more advance routines described in
-the following chapter to perform more complex or specialized operations.
-
-A right arrow symbol ($>$) is used to separate the input parameters from
-the output parameters in the  definition of each routine.  This symbol
-is not actually part of the calling sequence.  Note that
-the status parameter is both an input and an output parameter
-and must be initialized = 0 prior to calling the FITSIO subroutines.
-
-Refer to Chapter 9 for the definition of all the parameters
-used by these interface routines.

-\section{FITSIO Error Status Routines \label{FTVERS}}
-
-
-\begin{description}
-\item[1 ] Return the current version number of the fitsio library.
-    The version number will be incremented with each new
-   release of CFITSIO.
-\end{description}
-
-\begin{verbatim}
-        FTVERS( > version)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Return the descriptive text string corresponding to a FITSIO error
-    status code.   The 30-character length string contains a brief
-   description of the cause of the error.
-\end{description}
-
-\begin{verbatim}
-        FTGERR(status, > errtext)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Return the top (oldest) 80-character error message from the
-    internal FITSIO stack of error messages and shift any remaining
-    messages on the stack up one level.  Any FITSIO error will
-    generate one or more messages on the stack.  Call this routine
-    repeatedly to get each message in sequence.  The error stack is empty
-   when a blank string is returned.
-\end{description}
-
-\begin{verbatim}
-        FTGMSG( > errmsg)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]The FTPMRK routine puts an invisible marker on the
-   CFITSIO error stack.  The FTCMRK routine can then be
-   used to delete any more recent error messages on the stack, back to
-   the position of the marker.  This preserves any older error messages
-   on the stack.  FTCMSG simply clears the entire error message stack.
-  These routines are called without any arguments.
-\end{description}
-
-\begin{verbatim}
-        FTPMRK
-        FTCMRK
-        FTCMSG
-\end{verbatim}
-
-
-\begin{description}
-\item[5 ] Print out the error message corresponding to the input status
-    value and all the error messages on the FITSIO stack  to the specified
-    file stream  (stream can be either the string 'STDOUT' or 'STDERR').
-   If the input status value = 0 then this routine does nothing.
-\end{description}
-
-\begin{verbatim}
-       FTRPRT (stream, > status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Write an 80-character message to the FITSIO error stack.  Application
-    programs should not normally write to the stack, but there may be
-   some situations where this is desirable.

-\section{File I/O Routines}
-
-
-\begin{description}
-\item[1 ]Open an existing FITS file with readonly or readwrite access.
-   This routine always opens the primary array (the first HDU) of
-   the file, and does not move to a following extension, if one was
-   specified as part of the filename.   Use the FTNOPN routine to
-   automatically move to the extension.  This routine will also
-   open IRAF images (.imh format files) and raw binary data arrays
-   with READONLY access by first converting them on the fly into
-   virtual FITS images.  See the `Extended File Name Syntax' chapter
-   for more details.  The FTDKOPEN routine simply opens the specified
-   file without trying to interpret the filename using the extended
-  filename syntax.
-\end{description}
-
-\begin{verbatim}
-        FTOPEN(unit,filename,rwmode, > blocksize,status)
-        FTDKOPEN(unit,filename,rwmode, > blocksize,status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ]Open an existing FITS file with readonly or readwrite access
-   and move to a following extension, if one was specified as
-   part of the filename.  (e.g.,  'filename.fits+2' or
-   'filename.fits[2]' will move to the 3rd HDU in the file).
-   Note that this routine differs from FTOPEN in that it does not
-  have the redundant blocksize argument.
-\end{description}
-
-\begin{verbatim}
-        FTNOPN(unit,filename,rwmode, > status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ]Open an existing FITS file with readonly or readwrite access
-   and then move to the first HDU containing significant data, if a) an HDU
-   name or number to open was not explicitly specified as part of the
-   filename, and b) if the FITS file contains a null primary array (i.e.,
-   NAXIS = 0).  In this case, it will look for the first IMAGE HDU with
-   NAXIS > 0, or the first table that does not contain the strings `GTI'
-   (Good Time Interval) or `OBSTABLE' in the EXTNAME keyword value.  FTTOPN
-   is similar, except it will move to the first significant table HDU
-   (skipping over any image HDUs) in the file if a specific HDU name
-   or number is not specified.  FTIOPN will move to the first non-null
-  image HDU, skipping over any tables.
-\end{description}
-
-\begin{verbatim}
-        FTDOPN(unit,filename,rwmode, > status)
-        FTTOPN(unit,filename,rwmode, > status)
-        FTIOPN(unit,filename,rwmode, > status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]Open and initialize a new empty FITS file.   A template file may also be
-   specified to define the structure of the new file (see section 4.2.4).
-   The FTDKINIT routine simply creates the specified
-   file without trying to interpret the filename using the extended
-  filename syntax.
-\end{description}
-
-\begin{verbatim}
-        FTINIT(unit,filename,blocksize, > status)
-        FTDKINIT(unit,filename,blocksize, > status)
-\end{verbatim}
-
-\begin{description}
-\item[5 ]Close a FITS file previously opened with ftopen or ftinit
-\end{description}
-
-\begin{verbatim}
-        FTCLOS(unit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Move to a specified (absolute) HDU in the FITS file (nhdu = 1 for the
-   FITS primary array)
-\end{description}
-
-\begin{verbatim}
-        FTMAHD(unit,nhdu, > hdutype,status)
-\end{verbatim}
-
-\begin{description}
-\item[7 ] Create a primary array (if none already exists), or insert a
-    new IMAGE extension immediately following the CHDU, or
-    insert a new Primary Array at the beginning of the file.  Any
-    following extensions in the file will be shifted down to make room
-    for the new extension.  If the CHDU is the last HDU in the file
-    then the new image extension will simply be appended to the end of
-    the file.   One can force a new primary array to be inserted at the
-    beginning of the FITS file by setting status = -9 prior
-    to calling the routine.  In this case the existing primary array will be
-    converted to an IMAGE extension. The new extension (or primary
-    array) will become the CHDU.  The FTIIMGLL routine is identical
-    to the FTIIMG routine except that the 4th parameter (the length
-    of each axis) is an array of 64-bit integers rather than an array
-   of 32-bit integers.
-\end{description}
-
-\begin{verbatim}
-        FTIIMG(unit,bitpix,naxis,naxes, > status)
-        FTIIMGLL(unit,bitpix,naxis,naxesll, > status)

-\item[8 ] Insert a new ASCII TABLE extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new table extension will simply be appended to the
-    end of the file.  The new extension will become the CHDU. The FTITABLL
-    routine is identical
-    to the FTITAB routine except that the 2nd and 3rd parameters (that give
-    the size of the table) are 64-bit integers rather than
-    32-bit integers.  Under normal circumstances, the nrows and nrowsll
-    paramenters should have a value of 0; CFITSIO will automatically update
-   the number of rows as data is written to the table.

-\item[9 ] Insert a new binary table extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new bintable extension will simply be appended to the

-    routine is identical
-    to the FTIBIN routine except that the 2nd parameter (that gives
-    the length of the table) is a 64-bit integer rather than
-    a 32-bit integer. Under normal circumstances, the nrows and nrowsll

-\end{verbatim}
-
-\begin{description}
-\item[2 ] Put (append) a new keyword of the appropriate datatype into the CHU.
-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the
-     precision.  This will suppress trailing zeros, and will use a
-     fixed format rather than an exponential format,
-    depending on the magnitude of the value.
-\end{description}

-\begin{verbatim}
-        FTPKY[JKLS](unit,keyword,keyval,comment, > status)
-        FTPKY[EDFG](unit,keyword,keyval,decimals,comment, > status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ]Get the nth 80-character header record from the CHU.  The first keyword
-   in the header is at key\_no = 1;  if key\_no = 0 then this subroutine
-   simple moves the internal pointer to the beginning of the header
-   so that subsequent keyword operations will start at the top of
-  the header; it also returns a blank card value in this case.
-\end{description}

-\section{Data I/O Routines}
-
-The following routines read or write data values in the current HDU of
-the FITS file.  Automatic datatype conversion
-will be attempted for numerical datatypes if the specified datatype is
-different from the actual datatype of the FITS array or table column.

-\begin{description}
-\item[1 ]Write elements into the primary data array or image extension.
-\end{description}
-
-\begin{verbatim}
-        FTPPR[BIJKED](unit,group,fpixel,nelements,values, > status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Read elements from the primary data array or image extension.
-    Undefined array elements will be
-    returned with a value = nullval, unless nullval = 0 in which case no
-    checks for undefined pixels will be performed. The anyf parameter is
-    set to true (= .true.) if any of the returned
-   elements were undefined.
-\end{description}
-
-\begin{verbatim}
-        FTGPV[BIJKED](unit,group,fpixel,nelements,nullval, > values,anyf,status)
-\end{verbatim}

-\item[3 ] Write elements into an ASCII or binary table column. The `felem'
-    parameter applies only to vector columns in binary tables and is
-   ignored when writing to ASCII tables.
-\end{description}
-
-\begin{verbatim}
-        FTPCL[SLBIJKEDCM](unit,colnum,frow,felem,nelements,values, > status)

-\begin{description}
-\item[4 ] Read elements from an ASCII or binary table column.  Undefined
-    array elements will be returned with a value = nullval, unless nullval = 0
-    (or = ' ' for ftgcvs) in which case no checking for undefined values will
-    be performed. The ANYF parameter is set to true if any of the returned
-    elements are undefined.
-
-    Any column, regardless of it's intrinsic datatype, may be read as a
-    string.  It should be noted however that reading a numeric column
-    as a string is 10 - 100 times slower than reading the same column
-    as a number due to the large overhead in constructing the formatted
-    strings.  The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    datatype of the column.  The length of the returned strings  can be
-    determined with the ftgcdw routine.  The following TDISPn display
-    formats are currently supported:
-
-\begin{verbatim}
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
-\end{verbatim}
-  where w is the width in characters of the displayed values, m is the minimum

-\section{FITS File Open and Close Subroutines: \label{FTOPEN}}
-
-
-\begin{description}
-\item[1 ]Open an existing FITS file with readonly or readwrite access. The
-FTDKOPEN routine simply opens the specified file without trying to
-interpret the filename using the extended filename syntax. FTDOPN opens
-the file and
-also moves to the first HDU containing significant data, if no specific
-HDU is specified as part of the filename.  FTTOPN and FTIOPN are similar
-except that they will move to the first table HDU or image HDU, respectively,
-if a HDU name or number is not specified as part of the filename.
-\end{description}
-
-\begin{verbatim}
-        FTOPEN(unit,filename,rwmode, > blocksize,status)
-        FTDKOPEN(unit,filename,rwmode, > blocksize,status)
-
-        FTDOPN(unit,filename,rwmode, > status)
-        FTTOPN(unit,filename,rwmode, > status)
-        FTIOPN(unit,filename,rwmode, > status)
-\end{verbatim}
-
-
-\begin{description}
-\item[2 ]Open an existing FITS file with readonly or readwrite access
-   and move to a following extension, if one was specified as
-   part of the filename.  (e.g.,  'filename.fits+2' or
-   'filename.fits[2]' will move to the 3rd HDU in the file).
-   Note that this routine differs from FTOPEN in that it does not
-  have the redundant blocksize argument.
-\end{description}
-
-\begin{verbatim}
-        FTNOPN(unit,filename,rwmode, > status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Reopen a FITS file that was previously opened with
-    FTOPEN, FTNOPN, or FTINIT.  The newunit number
-    may then be treated as a separate file, and one may
-    simultaneously read or write to 2 (or more)  different extensions in
-    the same file.   The FTOPEN and FTNOPN routines (above) automatically
-    detects cases where a previously opened file is being opened again,
-    and then internally call FTREOPEN, so programs should rarely
-   need to explicitly call this routine.
-\end{description}
-
-\begin{verbatim}
-       FTREOPEN(unit, > newunit, status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]Open and initialize a new empty FITS file.
-   The FTDKINIT routine simply creates the specified
-   file without trying to interpret the filename using the extended
-  filename syntax.
-\end{description}
-
-\begin{verbatim}
-       FTINIT(unit,filename,blocksize, > status)
-       FTDKINIT(unit,filename,blocksize, > status)
-\end{verbatim}
-
-
-\begin{description}
-\item[5 ]  Create a new FITS file, using a template file to define its
-  initial size and structure.  The template may be another FITS HDU
-  or an ASCII template file.  If the input template file name
-  is blank, then this routine behaves the same as FTINIT.
-  The currently supported format of the ASCII template file is described
-  under the fits\_parse\_template routine (in the general Utilities
-  section), but this may change slightly later releases of
- CFITSIO.
-\end{description}
-
-\begin{verbatim}
-       FTTPLT(unit, filename, tplfilename, > status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ]Flush internal buffers of data to the output FITS file
-   previously opened with ftopen or ftinit.  The routine usually
-   never needs to be called, but doing so will ensure that
-   if the program subsequently aborts, then the FITS file will
-  have at least been closed properly.
-\end{description}
-
-\begin{verbatim}
-        FTFLUS(unit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[7 ]Close a FITS file previously opened with ftopen or ftinit
-\end{description}
-
-\begin{verbatim}
-        FTCLOS(unit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[8 ] Close and DELETE a FITS file previously opened with ftopen or ftinit.
-    This routine may be  useful in cases where a FITS file is created, but
-   an error occurs which prevents the complete file from being written.
-\end{description}
-
-\begin{verbatim}
-        FTDELT(unit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[9 ] Get the value of an unused I/O unit number which may then be used
-    as input to FTOPEN or FTINIT.  This routine searches for the first
-    unused unit number in the range from with 99 down to 50.   This
-    routine just keeps an internal list of the allocated unit numbers
-    and does not physically check that the Fortran unit is available (to be
-    compatible with the SPP version of FITSIO).  Thus users must not
-    independently allocate any unit numbers in the range 50 - 99
-    if this routine is also to be used in the same program.  This
-    routine is provided for convenience only, and it is not required
-   that the unit numbers used by FITSIO be allocated by this routine.
-\end{description}
-
-\begin{verbatim}
-        FTGIOU( > iounit, status)
-\end{verbatim}
-
-\begin{description}
-\item[10]  Free (deallocate) an I/O unit number which was previously allocated
-    with FTGIOU.   All previously allocated unit numbers may be
-   deallocated at once by calling FTFIOU with iounit = -1.
-\end{description}
-
-\begin{verbatim}
-        FTFIOU(iounit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[11]  Return the Fortran unit number that corresponds to the C fitsfile
-pointer value, or vice versa.  These 2 C routines may be useful in
-mixed language programs where both C and Fortran subroutines need
-to access the same file.  For example, if a FITS file is opened
-with unit 12 by a Fortran subroutine, then a C routine within the
-same program could get the fitfile pointer value to access the same file
-by calling  'fptr = CUnit2FITS(12)'.  These routines return a value
-of zero if an error occurs.
-\end{description}
-
-\begin{verbatim}
-      int       CFITS2Unit(fitsfile *ptr);
-      fitsfile* CUnit2FITS(int unit);
-\end{verbatim}
-
-
-\begin{description}
-\item[11]  Parse the input filename and return the HDU number that would be
-moved to if the file were opened with FTNOPN.    The returned HDU
-number begins with 1 for the primary array, so for example, if the
-input filename = `myfile.fits[2]' then hdunum = 3 will be returned.
-FITSIO does not open the file to check if the extension actually exists
-if an extension number is specified. If an extension *name* is included
-in the file name specification (e.g.  `myfile.fits[EVENTS]' then this
-routine will have to open the FITS file and look for the position of
-the named extension, then close file again.  This is not possible if
-the file is being read from the stdin stream, and an error will be
-returned in this case.  If the filename does not specify an explicit
-extension (e.g. 'myfile.fits') then hdunum = -99 will be returned,
-which is functionally equivalent to hdunum = 1. This routine is mainly
-used for backward compatibility in the ftools software package and is
-not recommended for general use.  It is generally better and more
-efficient to first open the FITS file with FTNOPN, then use FTGHDN to
-determine which HDU in the file has been opened, rather than calling
- FTEXTN followed by a call to FTNOPN.
-\end{description}
-
-\begin{verbatim}
-        FTEXTN(filename, > nhdu, status)
-\end{verbatim}
-
-\begin{description}
-\item[12] Return the name of the opened FITS file.
-\end{description}
-
-\begin{verbatim}
-        FTFLNM(unit, > filename, status)
-\end{verbatim}
-
-\begin{description}
-\item[13] Return the I/O mode of the open FITS file (READONLY = 0, READWRITE = 1).
-\end{description}
-
-\begin{verbatim}
-        FTFLMD(unit, > iomode, status)
-\end{verbatim}
-
-\begin{description}
-\item[14] Return the file type of the opened FITS file (e.g. 'file://', 'ftp://',
-  etc.).
-\end{description}
-
-\begin{verbatim}
-        FTURLT(unit, > urltype, status)
-\end{verbatim}
-
-\begin{description}
-\item[15]  Parse the input filename or URL into its component parts: the file
-type (file://, ftp://, http://, etc), the base input file name, the
-name of the output file that the input file is to be copied to prior
-to opening, the HDU or extension specification, the filtering
-specifier, the binning specifier, and the column specifier.  Blank
-strings will be returned for any components that are not present
-in the input file name.
-\end{description}
-
-\begin{verbatim}
-       FTIURL(filename, > filetype, infile, outfile, extspec, filter,
-               binspec, colspec, status)
-\end{verbatim}
-
-\begin{description}
-\item[16] Parse the input file name and return the root file name.  The root
-name includes the file type if specified, (e.g.  'ftp://' or 'http://')
-and the full path name, to the extent that it is specified in the input
-filename.  It does not include the HDU name or number, or any filtering
-specifications.
-\end{description}
-
-\begin{verbatim}
-       FTRTNM(filename, > rootname, status)
-\end{verbatim}
-
-
-\begin{description}
-\item[16] Test if the input file or a compressed version of the file (with
-a .gz, .Z, .z, or .zip extension) exists on disk.  The returned value of
-the 'exists' parameter will have 1 of the 4 following values:
-
-\begin{verbatim}
-   2:  the file does not exist, but a compressed version does exist
-   1:  the disk file does exist
-   0:  neither the file nor a compressed version of the file exist
-  -1:  the input file name is not a disk file (could be a ftp, http,
-       smem, or mem file, or a file piped in on the STDIN stream)
-\end{verbatim}
-
-\end{description}
-
-\begin{verbatim}
-      FTEXIST(filename, > exists, status);
-\end{verbatim}
-
-\section{HDU-Level Operations \label{FTMAHD}}
-
-When a FITS file is first opened or created, the internal buffers in
-FITSIO automatically point to the first HDU in the file.  The following
-routines may be used to move to another HDU in the file.  Note that
-the HDU numbering convention used in FITSIO  denotes the primary array
-as the first HDU, the first extension in a FITS file is the second HDU,
-and so on.
-
-
-\begin{description}
-\item[1 ] Move to a specified (absolute) HDU in the FITS file (nhdu = 1 for the
-   FITS primary array)
-\end{description}
-
-\begin{verbatim}
-        FTMAHD(unit,nhdu, > hdutype,status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ]Move to a new (existing) HDU forward or backwards relative to the CHDU
-\end{description}
-
-\begin{verbatim}
-        FTMRHD(unit,nmove, > hdutype,status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Move to the (first) HDU which has the specified extension type and
-    EXTNAME (or HDUNAME) and EXTVER keyword values.  The hdutype parameter
-    may have
-    a value of IMAGE\_HDU (0), ASCII\_TBL (1), BINARY\_TBL (2), or ANY\_HDU (-1)
-    where ANY\_HDU means that only the extname and extver values will be
-    used to locate the correct extension.  If the input value of
-    extver is 0 then the EXTVER keyword is ignored and the first HDU
-    with a matching EXTNAME (or HDUNAME) keyword will be found.  If no
-    matching HDU is found in the file then the current HDU will remain
-    unchanged
-   and a status = BAD\_HDU\_NUM (301) will be returned.
-\end{description}
-
-\begin{verbatim}
-        FTMNHD(unit, hdutype, extname, extver, > status)
-\end{verbatim}
-
-\begin{description}
-\item[4 ]Get the number of the current HDU in the FITS file (primary array = 1)
-\end{description}
-
-\begin{verbatim}
-        FTGHDN(unit, > nhdu)
-\end{verbatim}
-
-\begin{description}
-\item[5 ] Return the type of the current HDU in the FITS file.  The possible
-   values for hdutype are IMAGE\_HDU (0), ASCII\_TBL (1), or BINARY\_TBL (2).
-\end{description}
-
-\begin{verbatim}
-        FTGHDT(unit, > hdutype, status)
-\end{verbatim}
-
-\begin{description}
-\item[6 ] Return the total number of HDUs in the FITS file.
-   The CHDU remains unchanged.
-\end{description}
-
-\begin{verbatim}
-        FTTHDU(unit, > hdunum, status)
-\end{verbatim}
-
-\begin{description}
-\item[7 ]Create (append) a new empty HDU following the last extension that
-    has been previously accessed by the program.   This will overwrite
-    any extensions in an existing FITS file if the program has not already
-    moved to that (or a later) extension using the FTMAHD or FTMRHD routines.
-    For example, if an existing FITS file contains a primary array and 5
-    extensions and a program (1) opens the FITS file, (2) moves to
-    extension 4, (3) moves back to the primary array, and (4) then calls
-    FTCRHD, then the new extension will be written following the 4th
-   extension, overwriting the existing 5th extension.
-\end{description}
-
-\begin{verbatim}
-        FTCRHD(unit, > status)
-\end{verbatim}
-
-
-\begin{description}
-\item[8 ] Create a primary array (if none already exists), or insert a
-    new IMAGE extension immediately following the CHDU, or
-    insert a new Primary Array at the beginning of the file.  Any
-    following extensions in the file will be shifted down to make room
-    for the new extension.  If the CHDU is the last HDU in the file
-    then the new image extension will simply be appended to the end of
-    the file.   One can force a new primary array to be inserted at the
-    beginning of the FITS file by setting status = -9 prior
-    to calling the routine.  In this case the existing primary array will be
-    converted to an IMAGE extension. The new extension (or primary
-    array) will become the CHDU.  The FTIIMGLL routine is identical
-    to the FTIIMG routine except that the 4th parameter (the length
-    of each axis) is an array of 64-bit integers rather than an array
-   of 32-bit integers.
-\end{description}
-
-\begin{verbatim}
-        FTIIMG(unit,bitpix,naxis,naxes, > status)
-        FTIIMGLL(unit,bitpix,naxis,naxesll, > status)
-\end{verbatim}
-
-\begin{description}
-\item[9 ] Insert a new ASCII TABLE extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new table extension will simply be appended to the
-    end of the file.  The new extension will become the CHDU. The FTITABLL
-    routine is identical
-    to the FTITAB routine except that the 2nd and 3rd parameters (that give
-    the size of the table) are 64-bit integers rather than
-   32-bit integers.
-\end{description}
-
-\begin{verbatim}
-        FTITAB(unit,rowlen,nrows,tfields,ttype,tbcol,tform,tunit,extname, >
-               status)
-        FTITABLL(unit,rowlenll,nrowsll,tfields,ttype,tbcol,tform,tunit,extname, >
-               status)
-\end{verbatim}
-
-
-\begin{description}
-\item[10]  Insert a new binary table extension immediately following the CHDU.
-    Any following extensions will be shifted down to make room for
-    the new extension.  If there are no other following extensions
-    then the new bintable extension will simply be appended to the
-    end of the file.  The new extension will become the CHDU. The FTIBINLL
-    routine is identical
-    to the FTIBIN routine except that the 2nd parameter (that gives
-    the length of the table) is a 64-bit integer rather than
-   a 32-bit integer.
-\end{description}
-
-\begin{verbatim}
-        FTIBIN(unit,nrows,tfields,ttype,tform,tunit,extname,varidat > status)
-        FTIBINLL(unit,nrowsll,tfields,ttype,tform,tunit,extname,varidat > status)
-
-\end{verbatim}
-
-
-\begin{description}
-\item[11]  Resize an image by modifing the size, dimensions, and/or datatype of the
-    current primary array or image extension. If the new image, as specified
-    by the input arguments, is larger than the current existing image
-    in the FITS file then zero fill data will be inserted at the end
-    of the current image and any following extensions will be moved
-    further back in the file.  Similarly, if the new image is

-    This routine rewrites the BITPIX, NAXIS, and NAXISn keywords
-    with the appropriate values for new image. The FTRSIMLL routine is identical
-    to the FTRSIM routine except that the 4th parameter (the length

-\item[12] Delete the CHDU in the FITS file.  Any following HDUs will be shifted

-    to the following extension.  If there are no following extensions
-    then the CHDU will be redefined to point to the previous HDU.  The

-\section{Define or Redefine the structure of the CHDU \label{FTRDEF}}
-
-It should rarely be necessary to call the subroutines in this section.
-FITSIO internally calls these routines whenever necessary, so any calls
-to these routines by application programs will likely be redundant.
-
-
-\begin{description}
-\item[1 ] This routine forces FITSIO to scan the current header keywords that
-    define the structure of the HDU (such as the NAXISn, PCOUNT and GCOUNT
-    keywords) so that it can initialize the internal buffers that describe
-    the HDU structure.  This routine may be used instead of the more
-    complicated calls to ftpdef, ftadef or ftbdef.  This routine is
-    also very useful for reinitializing the structure of an HDU,
-    if the number of rows in a table, as specified by the NAXIS2 keyword,
-   has been modified from its initial value.

-\begin{description}
-\item[2 ]Define the structure of the primary array or IMAGE extension.  When
-   writing GROUPed FITS files that by convention set the NAXIS1 keyword
-   equal to 0, ftpdef must be called with naxes(1) = 1, NOT 0, otherwise
-   FITSIO will report an error status=308 when trying to write data
-   to a group. Note: it is usually simpler to call FTRDEF rather
-  than this routine.

-\begin{description}
-\item[5 ] Define the size of the Current Data Unit, overriding the length
-    of the data unit as previously defined by ftpdef, ftadef, or ftbdef.
-    This is useful if one does not know the total size of the data unit until
-    after the data have been written.  The size (in bytes) of an ASCII or
-    Binary table is given by NAXIS1 * NAXIS2.  (Note that to determine the
-    value of NAXIS1 it is often more convenient to read the value of the
-    NAXIS1 keyword from the output file, rather than computing the row
-    length directly from all the TFORM keyword values).  Note: it

-    location NAXIS1 x NAXIS2.  This routine is only relevant for
-    binary tables which contain variable length array columns (with
-    TFORMn = 'Pt').  This subroutine also automatically writes
-    the value of theap to a keyword in the extension header.  This
-    subroutine must be called after the required keywords have been

-\subsection{Header Space and Position Routines \label{FTHDEF}}
-
-
-\begin{description}
-\item[1 ] Reserve space in the CHU for MOREKEYS more header keywords.
-    This subroutine may be called to reserve space for keywords which are
-    to be written at a later time, after the data unit or subsequent
-    extensions have been written to the FITS file.  If this subroutine is
-    not explicitly called, then the initial size of the FITS header will be
-    limited to the space available at the time that  the first data is written
-    to the associated data unit.   FITSIO has the ability to dynamically
-    add more space to the header if needed, however it is more efficient
-   to preallocate the required space if the size is known in advance.
-\end{description}

-\subsection{Read or Write Standard Header Routines \label{FTPHPR}}
-
-These subroutines provide a simple method of reading or writing most of
-the keyword values that are normally required in a FITS files.  These
-subroutines are provided for convenience only and are not required to
-be used.  If preferred, users may call the lower-level subroutines
-described in the previous section to individually read or write the
-required keywords.  Note that in most cases, the required keywords such
-as NAXIS, TFIELD, TTYPEn, etc, which define the structure of the HDU
-must be written to the header before any data can be written to the
-image or table.
-
-
-\begin{description}
-\item[1 ] Put the primary header or IMAGE extension keywords into the CHU.
-There are 2 available routines: The simpler FTPHPS routine is
-equivalent to calling ftphpr with the default values of SIMPLE = true,
-pcount = 0, gcount = 1, and EXTEND = true.  PCOUNT, GCOUNT and EXTEND
-keywords are not required in the primary header and are only written if
-pcount is not equal to zero, gcount is not equal to zero or one, and if
-extend is TRUE, respectively.  When writing to an IMAGE extension, the
-SIMPLE and EXTEND parameters are ignored.

-\item[5 ]Put the binary table header keywords into the CHU. The optional
-   TUNITn and EXTNAME keywords are written only if the input string
-   values are not blank.  The pcount parameter, which specifies the
-   size of the variable length array heap, should initially = 0;
-   FITSIO will automatically update the PCOUNT keyword value if any
-   variable length array data is written to the heap.  The TFORM keyword
-   value for variable length vector columns should have the form 'Pt(len)'
-   or '1Pt(len)' where `t' is the data type code letter (A,I,J,E,D, etc.)
-   and  `len' is an integer specifying the maximum length of the vectors
-   in that column (len must be greater than or equal to the longest
-   vector in the column).  If `len' is not specified when the table is
-   created (e.g., the input TFORMn value is just '1Pt') then FITSIO will
-   scan the column when the table is first closed and will append the
-   maximum length to the TFORM keyword value.  Note that if the table
-   is subsequently modified to increase the maximum length of the vectors
-   then the modifying program is responsible for also updating the TFORM
-  keyword value.

-\begin{verbatim}
-        FTPDAT(unit, > status)

-\begin{description}
-\item[5 ] Put (append) a new keyword of the appropriate datatype into the CHU.
-    Note that FTPKYS will only write string values up to 68 characters in
-    length; longer strings will be truncated.  The FTPKLS routine can be
-    used to write longer strings, using a non-standard FITS convention.
-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the
-     precision.  This will suppress trailing zeros, and will use a
-     fixed format rather than an exponential format,
-    depending on the magnitude of the value.

-\begin{description}
-\item[6 ] Put (append) a string valued keyword into the CHU which may be longer
-    than 68 characters in length.  This uses the Long String Keyword
-    convention that is described in the "Usage Guidelines and Suggestions"
-    section of this document.  Since this uses a non-standard FITS
-    convention to encode the long keyword string, programs which use
-    this routine should also call the FTPLSW routine to add some COMMENT
-    keywords to warn users of the FITS file that this convention is
-    being used.  FTPLSW also writes a keyword called LONGSTRN to record
-    the version of the longstring convention that has been used, in case
-    a new convention is adopted at some point in the future.   If the
-    LONGSTRN keyword is already present in the header, then FTPLSW will
-   simply return and will not write duplicate keywords.

-    The floating point keyword value is constructed by concatenating the
-    input integer value with the input double precision fraction value
-    (which must have a value between 0.0 and 1.0). The FTGKYT routine should
-    be used to read this keyword value, because the other keyword reading

-\subsection{Read Keyword Subroutines \label{FTGREC}}
-
-These routines return the value of the specified keyword(s).  Wild card
-characters (*, ?, or \#) may be used when specifying the name of the keyword
-to be read: a '?' will match any single character at that position in the
-keyword name and a '*' will match any length (including zero) string of
-characters.  The '\#' character will match any consecutive string of
-decimal digits (0 - 9). Note that when a wild card is used in the input
-keyword name, the routine will only search for a match from the current
-header position to the end of the header.  It will not resume the search
-from the top of the header back to the original header position as is done
-when no wildcards are included in the keyword name.  If the desired
-keyword string is 8-characters long (the maximum length of a keyword
-name) then a '*' may be appended as the ninth character of the input
-name to force the keyword search to stop at the end of the header
-(e.g., 'COMMENT *' will search for the next COMMENT keyword).  The
-ffgrec routine may be used to set the starting position when doing
-wild card searches.
-
-
-\begin{description}
-\item[1 ]Get the nth 80-character header record from the CHU.  The first keyword
-   in the header is at key\_no = 1;  if key\_no = 0 then this subroutine

-    The strings in inclist and exclist may contain wild card characters
-    (*, ?, and \#) as described at the beginning of this section.
-    This routine searches from the current header position to the
-    end of the header, only, and does not continue the search from
-    the top of the header back to the original position.  The current
-    header position may be reset with the ftgrec routine.  Note

-     The E and D versions of this routine have the added feature that
-     if the 'decimals' parameter is negative, then the 'G' display
-     format rather then the 'E' format will be used when constructing
-     the keyword value, taking the absolute value of 'decimals' for the

-\section{Data Scaling and Undefined Pixel Parameters  \label{FTPSCL}}
-
-These subroutines define or modify the internal parameters used by
-FITSIO to either scale the data or to represent undefined pixels.
-Generally FITSIO will scale the data according to the values of the BSCALE
-and BZERO (or TSCALn and TZEROn) keywords, however these subroutines
-may be used to override the keyword values.  This may be useful when
-one wants to read or write the raw unscaled values in the FITS file.
-Similarly, FITSIO generally uses the value of the BLANK or TNULLn
-keyword to signify an undefined pixel, but these routines may be used
-to override this value.  These subroutines do not create or modify the
-corresponding header keyword values.
-
-
-\begin{description}
-\item[1 ] Reset the scaling factors in the primary array or image extension; does
-    not change the BSCALE and BZERO keyword values and only affects the
-    automatic scaling performed when the data elements are written/read
-    to/from the FITS file.   When reading from a FITS file the returned
-    data value = (the value given in the FITS array) * BSCALE + BZERO.
-    The inverse formula is used when writing data values to the FITS
-    file.  (NOTE: BSCALE and BZERO must be declared as Double Precision
-   variables).

-\section{FITS Primary Array or IMAGE Extension I/O Subroutines \label{FTPPR}}
-
-    These subroutines put or get data values in the primary data array
-(i.e., the first HDU in the FITS file) or an IMAGE extension.  The
-data array is represented as a single one-dimensional array of
-pixels regardless of the actual dimensionality of the array, and the
-FPIXEL parameter gives the position within this 1-D array of the first
-pixel to read  or write.  Automatic data type conversion is performed
-for numeric data (except for complex data types) if the data type of
-the primary array (defined by the BITPIX keyword) differs from the data
-type of the array in the calling subroutine.  The data values are also
-scaled by the BSCALE and BZERO header values as they are being written
-or read from the FITS array.  The ftpscl subroutine MUST be
-called to define the scaling parameters when writing data to the FITS
-array or to override the default scaling value given in the header when
-reading the FITS array.
-
-    Two sets of subroutines are provided to read the data array which
-differ in the way undefined pixels are handled.  The first set of
-routines (FTGPVx) simply return an array of data elements in which
-undefined pixels are set equal to a value specified by the user in the
-'nullval' parameter.  An additional feature of these subroutines is
-that if the user sets nullval = 0, then no checks for undefined pixels
-will be performed, thus increasing the speed of the program.  The
-second set of routines (FTGPFx) returns the data element array and, in
-addition, a logical array which defines whether the corresponding data
-pixel is undefined.  The latter set of subroutines may be more
-convenient to use in some circumstances, however, it requires an
-additional array of logical values which can be unwieldy when working
-with large data arrays.  Also for programmer convenience, sets of
-subroutines to directly read or write 2 and 3 dimensional arrays  have
-been provided, as well as a set of subroutines to read or write any
-contiguous rectangular subset of pixels within the n-dimensional array.
-
-
-\begin{description}
-\item[1 ] Get the data type of the image (= BITPIX value).  Possible returned
-    values are: 8, 16, 32, 64, -32, or -64 corresponding to unsigned byte,
-    signed 2-byte integer, signed 4-byte integer, signed 8-byte integer,
-    real, and double.
-
-    The second subroutine is similar to FTGIDT, except that if the image
-    pixel values are scaled, with non-default values for the BZERO and
-    BSCALE keywords, then this routine will return the 'equivalent'
-    data type that is needed to store the scaled values.  For example,
-    if BITPIX = 16 and BSCALE = 0.1 then the equivalent data type is
-    floating point, and -32 will be returned.  There are 2 special cases:
-    if the image contains unsigned 2-byte integer values, with BITPIX =
-    16, BSCALE = 1, and BZERO = 32768, then this routine will return
-    a non-standard value of 20 for the bitpix value.  Similarly if the
-    image contains unsigned 4-byte integers, then bitpix will
-   be returned with a value of 40.

-The following subroutines transfer a rectangular subset of the pixels
-in a FITS N-dimensional image to or from an array which has been

-are integer arrays which specify the starting and ending pixels in each
-dimension of the FITS image that are to be read or written.  (Note that
-these are the starting and ending pixels in the FITS image, not in the
-declared array). The array parameter is treated simply as a large
-one-dimensional array of the appropriate datatype containing the pixel
-values; The pixel values in the FITS array are read/written  from/to
-this program array in strict sequence without any gaps;  it is up to
-the calling routine to correctly interpret the dimensionality of this
-array.  The two families of FITS reading routines (FTGSVx and FTGSFx

-example, if incs(1)=2 and incs(2)=3 when reading a 2-dimensional
-FITS image, then only every other pixel in the first dimension
-and every 3rd pixel in the second dimension will be returned in

-\subsection{Column Information Subroutines \label{FTGCNO}}
-
-
-\begin{description}
-\item[1 ]  Get the number of rows or columns in the current FITS table.
-     The number of rows is given by the NAXIS2 keyword and the
-     number of columns is given by the TFIELDS keyword in the header
-     of the table.  The FTGNRWLL routine is identical to FTGNRW except
-     that the number of rows is returned as a 64-bit integer rather
-    than a 32-bit integer.
-\end{description}
-
-\begin{verbatim}
-        FTGNRW(unit, > nrows, status)
-        FTGNRWLL(unit, > nrowsll, status)
-        FTGNCL(unit, > ncols, status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Get the table column number (and name) of the column whose name
-matches an input template name.  The table column names are defined by
-the TTYPEn keywords in the FITS header.  If a column does not have a
-TTYPEn keyword, then these routines assume that the name consists of
-all blank characters.  These 2 subroutines perform the same function
-except that FTGCNO only returns the number of the matching column whereas
-FTGCNN also returns the name of the column.  If CASESEN = .true. then
-the column name match will be case-sensitive.
-
-The input column name template (COLTEMPLATE) is (1) either the exact
-name of the column to be searched for, or (2) it may contain wild cards
-characters (*, ?, or \#), or (3) it may contain the number of the desired
-column (where the number is expressed as ASCII digits).  The first 2 wild
-cards behave similarly to UNIX filename matching:  the '*' character matches
-any sequence of characters (including zero characters) and the '?'
-character matches any single character.  The \# wildcard will match
-any consecutive string of decimal digits (0-9).  As an example, the template
-strings 'AB?DE', 'AB*E', and 'AB*CDE' will all match the string
-'ABCDE'.  If more than one column name in the table matches the
-template string, then the first match is returned and the status value
-will be set to 237 as a warning that a unique match was not found.  To
-find the other cases that match the template, simply call the
-subroutine again leaving the input status value equal to  237 and the
-next matching name will then be returned.  Repeat this process until a
-status = 219 (column name not found) is returned.  If these subroutines
-fail to match the template to any of the columns in the table, they
-lastly check if the template can be interpreted as a simple positive
-integer (e.g., '7', or '512') and if so, they return that column
-number.  If no matches are found then a status = 219 error is
-returned.

-\item[3 ] Get the datatype of a column in an ASCII or binary table.  This
-    routine returns an integer code value corresponding to the datatype
-    of the column. (See the FTBNFM and FTASFM subroutines in the Utilities
-    section of this document for a list of the code values).  The vector
-    repeat count (which is alway 1 for ASCII table columns) is also returned.
-    If the specified column has an ASCII character datatype (code = 16) then
-    the width of a unit string in the column is also returned.  Note that
-    this routine supports the local convention for specifying arrays of
-    strings within a binary table character column, using the syntax
-    TFORM = 'rAw' where 'r' is the total number of characters (= the width
-    of the column) and 'w' is the width of a unit string within the column.
-    Thus if the column has TFORM = '60A12' then this routine will return
-    datacode = 16, repeat = 60, and width = 12.  (The TDIMn
-    keyword may also be used to specify the unit string length; The pair
-    of keywords TFORMn = '60A' and TDIMn = '(12,5)'  would have the
-    same effect as TFORMn = '60A12').
-
-   The second routine, FTEQTY is similar except that in
-   the case of scaled integer columns it returns the 'equivalent' data
-   type that is needed to store the scaled values, and not necessarily
-   the physical data type of the unscaled values as stored in the FITS
-   table.  For example if a '1I' column in a binary table has TSCALn =
-   1 and TZEROn = 32768, then this column effectively contains unsigned
-   short integer values, and thus the returned value of typecode will
-   be the code for an unsigned short integer, not a signed short integer.
-   Similarly, if a column has TTYPEn = '1I'
-   and TSCALn = 0.12, then the returned typecode
-  will be the code for a 'real' column.

-\item[6 ] Get information about an existing binary table column. (NOTE: TSCAL and

-    by the TFORMn keyword (e.g., 'I', 'J','E', 'D', etc.).  In the case
-    of an ASCII character column, DATATYPE will have a value of the
-    form 'An' where 'n' is an integer expressing the width of the field
-    in characters.  For example, if TFORM = '160A8' then FTGBCL will return
-    DATATYPE='A8' and REPEAT=20.   All the returned parameters are scalar
-   quantities.

-\subsection{Low-Level Table Access Subroutines \label{FTGTBS}}
-
-The following subroutines provide low-level access to the data in ASCII
-or binary tables and are mainly useful as an efficient way to copy all
-or part of a table from one location to another.  These routines simply
-read or write the specified number of consecutive bytes in an ASCII or
-binary table, without regard for column boundaries or the row length in
-the table.  The first two subroutines read or write consecutive bytes
-in a table to or from a character string variable, while the last two
-subroutines read or write consecutive bytes to or from a variable
-declared as a numeric data type (e.g., INTEGER, INTEGER*2, REAL, DOUBLE
-PRECISION).  These routines do not perform any machine dependent data
-conversion or byte swapping, except that conversion to/from ASCII
-format is performed by the FTGTBS and FTPTBS routines on machines which
-do not use ASCII character codes in the internal data representations
-(e.g., on IBM mainframe computers).

-\begin{description}
-\item[1 ] Read a consecutive string of characters from an ASCII table

-\subsection{Read and Write Column Data Routines \label{FTPCLS}}
-
-These subroutines put or get data values in the current ASCII or Binary table
-extension.  Automatic data type conversion is performed for numerical data
-types (B,I,J,E,D) if the data type of the column (defined by the TFORM keyword)
-differs from the data type of the calling subroutine.  The data values are also
-scaled by the TSCALn and TZEROn header values as they are being written to
-or read from the FITS array.  The fttscl subroutine MUST be used to define the
-scaling parameters when writing data to the table or to override the default
-scaling values given in the header when reading from the table.
-Note that it is *not* necessary to insert rows in a table before
-writing data to those rows (indeed, it would be inefficient to do so).
-Instead, one may simply write data to any row of the table, whether that
-row of data already exists or not.
-
-    In the case of binary tables with vector elements, the 'felem'
-parameter defines the starting pixel within the element vector.  This
-parameter is ignored with ASCII tables. Similarly, in the case of
-binary tables the 'nelements' parameter specifies the total number of
-vector values read or written (continuing on subsequent rows if
-required) and not the number of table elements.  Two sets of
-subroutines are provided to get the column data which differ in the way
-undefined pixels are handled.  The first set of routines (FTGCV)
-simply return an array of data elements in which undefined pixels are
-set equal to a value specified by the user in the 'nullval' parameter.
-An additional feature of these subroutines is that if the user sets
-nullval = 0, then no checks for undefined pixels will be performed,
-thus increasing the speed of the program.  The second set of routines
-(FTGCF) returns the data element array and in addition a logical array
-of flags which defines whether the corresponding data pixel is undefined.
-
-    Any column, regardless of it's intrinsic datatype, may be read as a
-    string.  It should be noted however that reading a numeric column
-    as a string is 10 - 100 times slower than reading the same column as
-    a number due to the large overhead in constructing the formatted
-    strings.    The display format of the returned strings will be
-    determined by the TDISPn keyword, if it exists, otherwise by the
-    datatype of the column.  The length of the returned strings can be
-    determined with the ftgcdw routine.  The following TDISPn display
-    formats are currently supported:
-
-\begin{verbatim}
-    Iw.m   Integer
-    Ow.m   Octal integer
-    Zw.m   Hexadecimal integer
-    Fw.d   Fixed floating point
-    Ew.d   Exponential floating point
-    Dw.d   Exponential floating point
-    Gw.d   General; uses Fw.d if significance not lost, else Ew.d
-\end{verbatim}
-  where w is the width in characters of the displayed values, m is the minimum
-  number of digits displayed, and d is the number of digits to the right of the
-  decimal.  The .m field is optional.

-
-    The alternate version of these routines, whose names end in 'LL'
-    after the datatype character, support large tables with more then

-\item[10] Read any consecutive set of bits from an 'X' or 'B' column and
-    interpret them as an unsigned n-bit integer. NBIT must be less than
-    or equal to 16 when calling FTGCXI, and less than or equal to 32 when
-    calling FTGCXJ; there is no limit on the value of NBIT for FTGCXD, but
-    the returned double precision value only has 48 bits of precision on
-    most 32-bit word machines.  The NBITS bits are interpreted as an
-    unsigned integer unless NBITS = 16 (in FTGCXI) or 32 (in FTGCXJ) in which
-    case the string of bits are interpreted as 16-bit or 32-bit 2's
-    complement signed integers.  If NROWS is greater than 1 then the
-    same set of bits will be read from sequential rows in the table
-    starting with row FROW.  Note that the numbering convention
-    used here for the FBIT parameter adopts 1 for the first element of the
-   vector of bits;  this is the Most Significant Bit of the integer value.

-\section{Row Selection and Calculator Routines \label{FTFROW}}
-
-These routines all parse and evaluate an input string containing a user
-defined arithmetic expression.  The first 3 routines select rows in a
-FITS table, based on whether the expression evaluates to true (not
-equal to zero) or false (zero).  The other routines evaluate the
-expression and calculate a value for each row of the table.  The
-allowed expression syntax is described in the row filter section in the
-earlier `Extended File Name Syntax' chapter of this document.  The
-expression may also be written to a text file, and the name of the
-file, prepended with a '@' character may be supplied for the 'expr'
-parameter (e.g.  '@filename.txt'). The  expression  in  the  file can
-be arbitrarily complex and extend over multiple lines of the file.
-Lines  that begin with 2 slash characters ('//') will  be ignored and
-may be used to add comments to the file.

-\section{Celestial Coordinate System Subroutines \label{FTGICS}}
-
-The FITS community has adopted a set of keyword conventions that define
-the transformations needed to convert between pixel locations in an
-image and the corresponding celestial coordinates on the sky, or more
-generally, that define world coordinates that are to be associated with
-any pixel location in an n-dimensional FITS array. CFITSIO is distributed
-with a couple of self-contained World Coordinate System (WCS) routines,
-however, these routines DO NOT support all the latest WCS conventions,
-so it is STRONGLY RECOMMENDED that software developers use a more robust
-external WCS library.  Several recommended libraries are:
-
-\begin{verbatim}
-  WCSLIB -  supported by Mark Calabretta
-  WCSTools - supported by Doug Mink
-  AST library - developed by the U.K. Starlink project
-\end{verbatim}
-
-More information about the WCS keyword conventions and links to all of
-these WCS libraries can be found on the FITS Support Office web site at
-http://fits.gsfc.nasa.gov under the WCS link.
-
-The functions provided in these external WCS libraries will need access to
-the  WCS information contained in the FITS file headers.  One convenient
-way to pass this information to the external library is to use  FITSIO
-to copy the header keywords into one long character string, and then
-pass this string to an interface routine in the external library that
-will extract the necessary WCS information (e.g., see the astFitsChan
-and astPutCards routines in the Starlink AST library).
-
-The following FITSIO routines DO NOT support the more recent WCS conventions
-that have been approved as part of the FITS standard.  Consequently,
-the following routines ARE NOW DEPRECATED.  It is STRONGLY RECOMMENDED
-that software developers not use these routines, and instead use an
-external WCS library, as described above.
-
-These routines are included mainly for backward compatibility with
-existing software.  They support the following standard map
-projections: -SIN, -TAN, -ARC, -NCP, -GLS, -MER, and -AIT (these are the
-legal values for the coordtype parameter).  These routines are based
-on similar functions in Classic AIPS.  All the angular quantities are
-given in units of degrees.
-
-
-\begin{description}
-\item[1 ] Get the values of all the standard FITS celestial coordinate system
-    keywords from the header of a FITS image (i.e., the primary array or
-    an image extension).  These values may then be passed to the subroutines
-    that perform the coordinate transformations.  If any or all of the WCS
-    keywords are not present, then default values will be returned. If
-    the first coordinate axis is the declination-like coordinate, then
-    this routine will swap them so that the longitudinal-like coordinate
-    is returned as the first axis.
-
-    If the file uses the newer 'CDj\_i' WCS transformation matrix
-    keywords instead of old style 'CDELTn' and 'CROTA2' keywords, then
-    this routine will calculate and return the values of the equivalent
-    old-style keywords.    Note that the conversion from the new-style
-    keywords to the old-style values is sometimes only an
-    approximation, so if the approximation is larger than an internally
-    defined threshold level, then CFITSIO will still return the
-    approximate WCS keyword values, but will also return with status =
-    506, to warn the calling program that approximations have been
-    made.  It is then up to the calling program to decide whether the
-    approximations are sufficiently accurate for the particular
-    application, or whether more precise WCS transformations must be
-   performed using new-style WCS keywords directly.

-\section{File Checksum Subroutines \label{FTPCKS}}
-
-The following routines either compute or validate the checksums for the
-CHDU.  The DATASUM keyword is used to store the numerical value of the
-32-bit, 1's complement checksum for the data unit alone.  If there is
-no data unit then the value is set to zero. The numerical value is
-stored as an ASCII string of digits, enclosed in quotes, because the
-value may be too large to represent as a 32-bit signed integer.  The
-CHECKSUM keyword is used to store the ASCII encoded COMPLEMENT of the
-checksum for the entire HDU.  Storing the complement, rather than the
-actual checksum, forces the checksum for the whole HDU to equal zero.
-If the file has been modified since the checksums were computed, then
-the HDU checksum will usually not equal zero.  These checksum keyword
-conventions are based on a paper by Rob Seaman published in the
-proceedings of the ADASS IV conference in Baltimore in November 1994
-and a later revision in June 1995.
-
-
-\begin{description}
-\item[1 ] Compute and write the DATASUM and CHECKSUM keyword values for the CHDU
-    into the current header.  The DATASUM value is the 32-bit checksum
-    for the data unit, expressed as a decimal integer enclosed in single
-    quotes. The CHECKSUM keyword value is a 16-character string which
-    is the ASCII-encoded value for the complement of the checksum for
-    the whole HDU.  If these keywords already exist, their values
-    will be updated only if necessary (i.e., if the file has been modified
-   since the original keyword values were computed).
-\end{description}

-\begin{verbatim}
-        FTPCKS(unit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[2 ] Update the CHECKSUM keyword value in the CHDU, assuming that the
-    DATASUM keyword exists and already has the correct value.  This routine
-    calculates the new checksum for the current header unit, adds it to the
-    data unit checksum, encodes the value into an ASCII string, and writes
-   the string to the CHECKSUM keyword.
-\end{description}
-
-\begin{verbatim}
-        FTUCKS(unit, > status)
-\end{verbatim}
-
-\begin{description}
-\item[3 ] Verify the CHDU by computing the checksums and comparing
-    them with the keywords.  The data unit is verified correctly
-    if the computed checksum equals the value of the DATASUM
-    keyword.  The checksum for the entire HDU (header plus data unit) is
-    correct if it equals zero.  The output DATAOK and HDUOK parameters
-    in this subroutine are integers which will have a value = 1
-    if the data or HDU is verified correctly, a value = 0
-    if the DATASUM or CHECKSUM keyword is not present, or value = -1
-   if the computed checksum is not correct.

-\section{ Date and Time Utility Routines \label{FTGSDT}}
-
-The following routines help to construct or parse the FITS date/time
-strings.   Starting in the year 2000, the FITS DATE keyword values (and
-the values of other `DATE-' keywords) must have the form 'YYYY-MM-DD'
-(date only) or 'YYYY-MM-DDThh:mm:ss.ddd...' (date and time) where the
-number of decimal places in the seconds value is optional.  These times
-are in UTC.  The older 'dd/mm/yy' date format may not be used for dates
-after 01 January 2000.

-\begin{description}
-\item[2 ] Get the current system date and time string ('YYYY-MM-DDThh:mm:ss').
-The time will be in UTC/GMT if available, as indicated by a returned timeref
-value = 0.  If the returned value of timeref = 1 then this indicates that
-it was not possible to convert the local time to UTC, and thus the local

-\item[3 ] Compare the input template string against the reference string
-    to see if they match.  The template string may contain wildcard
-    characters: '*' will match any sequence of characters (including
-    zero characters) and '?' will match any single character in the
-    reference string. The '\#' character will match any consecutive string
-    of decimal digits (0 - 9).  If CASESN = .true. then the match will be
-    case sensitive.  The returned MATCH parameter will be .true. if
-    the 2 strings match, and EXACT will be .true. if the match is
-    exact (i.e., if no wildcard characters were used in the match).

-    interpreted as the normal end-of-string terminator.  This routine returns
-    the position of the first null character in the header, or zero if there
-    are no nulls.  For example a returned value of 110 would indicate that
-    the first NULL is located in the 30th character of the second keyword
-    in the header (recall that each header record is 80 characters long).
-    Note that this is one of the few FITSIO routines in which the returned

-    columns are defined to be regular integers (code = 41).  Similarly,
-    Fixed decimal point columns (with TFORM = 'Fw.d') are defined to
-    be single precision reals (code = 42) if w is between 1 and 7 characters
-    wide, inclusive.  Wider 'F' columns will return a double precision

-\item[15] Parse a template string and return a formatted 80-character string
-    suitable for appending to (or deleting from) a FITS header file.
-    This subroutine is useful for parsing lines from an ASCII template file
-    and reformatting them into legal FITS header records.  The formatted
-    string may then be passed to the FTPREC, FTMCRD, or FTDKEY subroutines
-   to append or modify a FITS header record.
-\end{description}
-
-\begin{verbatim}
-        FTGTHD(template, > card,hdtype,status)
-\end{verbatim}
-    The input TEMPLATE character string generally should contain 3 tokens:
-    (1) the KEYNAME, (2) the VALUE, and (3) the COMMENT string.  The
-    TEMPLATE string must adhere to the following format:
-
-
-\begin{description}
-\item[- ]     The KEYNAME token must begin in columns 1-8 and be a maximum  of 8
-        characters long.  If the first 8 characters of the template line are
-        blank then the remainder of the line is considered to be a FITS comment
-        (with a blank keyword name).  A legal FITS keyword name may only
-        contain the characters A-Z, 0-9, and '-' (minus sign) and
-        underscore.  This subroutine will automatically convert any lowercase
-        characters to uppercase in the output string.  If KEYNAME = 'COMMENT'
-        or 'HISTORY' then the remainder of the line is considered to be a FITS
-       COMMENT or HISTORY record, respectively.
-\end{description}
-
-
-\begin{description}
-\item[- ]     The VALUE token must be separated from the KEYNAME token by one or more
-        spaces and/or an '=' character.  The datatype of the VALUE token
-        (numeric, logical, or character string) is automatically determined
-        and  the output CARD string is formatted accordingly.  The value
-        token may be forced to be interpreted as a string (e.g. if it is a
-        string of numeric digits) by enclosing it in single quotes.
-        If the value token is a character string that contains 1 or more
-        embedded blank space characters or slash ('/') characters then the
-       entire character string must be enclosed in single quotes.
-\end{description}
-
-
-\begin{description}
-\item[- ]     The COMMENT token is optional, but if present must be separated from
-       the VALUE token by a blank space or a  '/' character.
-\end{description}
-
-
-\begin{description}
-\item[- ]     One exception to the above rules is that if the first non-blank
-        character in the template string is a minus sign ('-') followed
-        by a single token, or a single token followed by an equal sign,
-        then it is interpreted as the name of a keyword which is to be
-       deleted from the FITS header.
-\end{description}
-
-
-\begin{description}
-\item[- ]     The second exception is that if the template string starts with
-        a minus sign and is followed by 2 tokens then the second token
-        is interpreted as the new name for the keyword specified by
-        first token.  In this case the old keyword name (first token)
-        is returned in characters 1-8 of the returned CARD string, and
-        the new keyword name (the second token) is returned in characters
-        41-48 of the returned CARD string.  These old and new names
-        may then be passed to the FTMNAM subroutine which will change
-       the keyword name.
-\end{description}
-
-    The HDTYPE output parameter indicates how the returned CARD string
-    should be interpreted:
-
-\begin{verbatim}
-        hdtype                  interpretation
-        ------           -------------------------------------------------
-           -2            Modify the name of the keyword given in CARD(1:8)
-                         to the new name given in CARD(41:48)
-
-           -1            CARD(1:8) contains the name of a keyword to be deleted
-                         from the FITS header.
-
-            0            append the CARD string to the FITS header if the
-                         keyword does not already exist, otherwise update
-                         the value/comment if the keyword is already present
-                         in the header.
-
-            1            simply append this keyword to the FITS header (CARD
-                         is either a HISTORY or COMMENT keyword).
-
-            2            This is a FITS END record; it should not be written
-                         to the FITS header because FITSIO automatically
-                         appends the END record when the header is closed.
-\end{verbatim}
-     EXAMPLES:  The following lines illustrate valid input template strings:
-
-\begin{verbatim}
-      INTVAL 7 This is an integer keyword
-      RVAL           34.6   /     This is a floating point keyword
-      EVAL=-12.45E-03  This is a floating point keyword in exponential notation
-      lval F This is a boolean keyword
-                  This is a comment keyword with a blank keyword name
-      SVAL1 = 'Hello world'   /  this is a string keyword
-      SVAL2  '123.5'  this is also a string keyword
-      sval3  123+  /  this is also a string keyword with the value '123+    '
-      # the following template line deletes the DATE keyword
-      - DATE
-      # the following template line modifies the NAME keyword to OBJECT
-      - NAME OBJECT
-\end{verbatim}
-
-\begin{description}
-\item[16]  Parse the input string containing a list of rows or row ranges, and
-     return integer arrays containing the first and last row in each
-     range.  For example, if rowlist = "3-5, 6, 8-9" then it will
-     return numranges = 3, rangemin = 3, 6, 8 and rangemax = 5, 6, 9.
-     At most, 'maxranges' number of ranges will be returned.  'maxrows'
-     is the maximum number of rows in the table; any rows or ranges
-     larger than this will be ignored.  The rows must be specified in
-     increasing order, and the ranges must not overlap. A minus sign
-     may be use to specify all the rows to the upper or lower bound, so
-     "50-" means all the rows from 50 to the end of the table, and "-"
-    means all the rows in the table, from 1 - maxrows.
-\end{description}

-\chapter{ The CFITSIO Iterator Function }
-
-The fits\_iterate\_data function in CFITSIO provides a unique method of
-executing an arbitrary user-supplied `work' function that operates on
-rows of data in  FITS tables or on pixels in FITS images.  Rather than
-explicitly reading and writing the FITS images or columns of data, one
-instead calls the CFITSIO iterator routine, passing to it the name of
-the user's work function that is to be executed along with a list of
-all the table columns or image arrays that are to be passed to the work
-function.  The CFITSIO iterator function then does all the work of
-allocating memory for the arrays, reading the input data from the FITS
-file, passing them to the work function, and then writing any output
-data back to the FITS file after the work function exits.  Because
-it is often more efficient to process only a subset of the total table
-rows at one time, the iterator function can determine the optimum
-amount of data to pass in each iteration and repeatedly call the work
-function until the entire table been processed.
-
-For many applications this single CFITSIO iterator function can
-effectively replace all the other CFITSIO routines for reading or
-writing data in FITS images or tables.  Using the iterator has several
-important advantages over the traditional method of reading and writing
-FITS data files:
-
-\begin{itemize}
-\item
-It cleanly separates the data I/O from the routine that operates on
-the data.  This leads to a more modular and `object oriented'
-programming style.
-
-\item
-It simplifies the application program by eliminating the need to allocate
-memory for the data arrays and eliminates most of the calls to the CFITSIO
-routines that explicitly read and write the data.
-
-\item
-It ensures that the data are processed as efficiently as possible.
-This is especially important when processing tabular data since
-the iterator function will calculate the most efficient number
-of rows in the table to be passed at one time to the user's work
-function on each iteration.
-
-\item
-Makes it possible for larger projects to develop a library of work
-functions that all have a uniform calling sequence and are all
-independent of the details of the FITS file format.
-
-\end{itemize}
-
-There are basically 2 steps in using the CFITSIO iterator function.
-The first step is to design the work function itself which must have a
-prescribed set of input parameters.  One of these parameters is a
-structure containing pointers to the arrays of data; the work function
-can perform any desired operations on these arrays and does not need to
-worry about how the input data were read from the file or how the
-output data get written back to the file.
-
-The second step is to design the driver routine that opens all the
-necessary FITS files and initializes  the input parameters to the
-iterator function.  The driver program calls the CFITSIO iterator
-function which then reads the data and passes it to the user's work
-function.
-
-Further details on using the iterator function can be found in the
-companion CFITSIO User's Guide, and in the iter\_a.f, iter\_b.f and
-iter\_c.f example programs.

-\chapter{  Extended File Name Syntax }
-
-
-\section{Overview}
-
-CFITSIO supports an extended syntax when specifying the name of the
-data file to be opened or created  that includes the following
-features:
-
-\begin{itemize}
-\item
-CFITSIO can read IRAF format images which have header file names that
-end with the '.imh' extension, as well as reading and writing FITS
-files,   This feature is implemented in CFITSIO by first converting the
-IRAF image into a temporary FITS format file in memory, then opening
-the FITS file.  Any of the usual CFITSIO routines then may be used to
-read the image header or data.  Similarly, raw binary data arrays can
-be read by converting them on the fly into virtual FITS images.
-
-\item
-FITS files on the Internet can be read (and sometimes written) using the FTP,
-HTTP, or ROOT protocols.
-
-\item
-FITS files can be piped between tasks on the stdin and stdout streams.
-
-\item
-FITS files can be read and written in shared memory.  This can potentially
-achieve much better data I/O performance compared to reading and
-writing the same FITS files on magnetic disk.
-
-\item
-Compressed FITS files in gzip or Unix COMPRESS format can be directly read.
-
-\item
-Output FITS files can be written directly in compressed gzip format,
-thus saving disk space.
-
-\item
-FITS table columns can be created, modified, or deleted 'on-the-fly' as
-the table is opened by CFITSIO.  This creates a virtual FITS file containing
-the modifications that is then opened by the application program.
-
-\item
-Table rows may be selected, or filtered out, on the fly when the table
-is opened by CFITSIO, based on an arbitrary user-specified expression.
-Only rows for which the expression evaluates to 'TRUE' are retained
-in the copy of the table that is opened by the application program.
-
-\item
-Histogram images may be created on the fly by binning the values in
-table columns, resulting in a virtual N-dimensional FITS image.  The
-application program then only sees the FITS image (in the primary
-array) instead of the original FITS table.
-\end{itemize}
-
-The latter 3 features in particular add very powerful data processing
-capabilities directly into CFITSIO, and hence into every task that uses
-CFITSIO to read or write FITS files.  For example, these features
-transform a very simple program that just copies an input FITS file to
-a new output file (like the `fitscopy' program that is distributed with
-CFITSIO) into a multipurpose FITS file processing tool.  By appending
-fairly simple qualifiers onto the name of the input FITS file, the user
-can perform quite complex table editing operations (e.g., create new
-columns, or filter out rows in a table) or create FITS images by
-binning or histogramming the values in table columns.  In addition,
-these functions have been coded using new state-of-the art algorithms
-that are, in some cases, 10 - 100 times faster than previous widely
-used implementations.
-
-Before describing the complete syntax for the extended FITS file names
-in the next section, here are a few examples of FITS file names that
-give a quick overview of the allowed syntax:
-
-\begin{itemize}
-\item
-{\tt 'myfile.fits'}: the simplest case of a FITS file on disk in the current
-directory.
-
-\item
-{\tt 'myfile.imh'}: opens an IRAF format image file and converts it on the
-fly into a temporary FITS format image in memory which can then be read with
-any other CFITSIO routine.
-
-\item
-{\tt rawfile.dat[i512,512]}: opens a raw binary data array (a 512 x 512
-short integer array in this case) and converts it on the fly into a
-temporary FITS format image in memory which can then be read with any
-other CFITSIO routine.
-
-\item
-{\tt myfile.fits.gz}: if this is the name of a new output file, the '.gz'
-suffix will cause it to be compressed in gzip format when it is written to
-disk.
-
-\item
-{\tt 'myfile.fits.gz[events, 2]'}:  opens and uncompresses the gzipped file
-myfile.fits then moves to the extension which has the keywords EXTNAME
-= 'EVENTS' and EXTVER = 2.
-
-\item
-{\tt '-'}:  a dash (minus sign) signifies that the input file is to be read
-from the stdin file stream, or that the output file is to be written to
-the stdout stream.
-
-\item
-{\tt 'ftp://legacy.gsfc.nasa.gov/test/vela.fits'}:  FITS files in any ftp
-archive site on the Internet may be directly opened with read-only
-access.
-
-\item
-{\tt 'http://legacy.gsfc.nasa.gov/software/test.fits'}: any valid URL to a
-FITS file on the Web may be opened with read-only access.
-
-\item
-{\tt 'root://legacy.gsfc.nasa.gov/test/vela.fits'}: similar to ftp access
-except that it provides write as well as read access to the files
-across the network. This uses the root protocol developed at CERN.
-
-\item
-{\tt 'shmem://h2[events]'}: opens the FITS file in a shared memory segment and
-moves to the EVENTS extension.
-
-\item
-{\tt 'mem://'}:  creates a scratch output file in core computer memory.  The
-resulting 'file' will disappear when the program exits, so this
-is mainly useful for testing purposes when one does not want a
-permanent copy of the output file.
-
-\item
-{\tt 'myfile.fits[3; Images(10)]'}: opens a copy of the image contained in the
-10th row of the 'Images' column in the binary table in the 3th extension
-of the FITS file.  The application just sees this single image as the
-primary array.
-
-\item
-{\tt 'myfile.fits[1:512:2, 1:512:2]'}: opens a section of the input image
-ranging from the 1st to the 512th pixel in  X and Y, and selects every
-second pixel in both dimensions, resulting in a 256 x 256 pixel image
-in this case.
-
-\item
-{\tt 'myfile.fits[EVENTS][col Rad = sqrt(X**2 + Y**2)]'}:  creates and opens
-a temporary file on the fly (in memory or on disk) that is identical to
-myfile.fits except that it will contain a new column in the EVENTS
-extension called 'Rad' whose value is computed using the indicated
-expression which is a function of the values in the X and Y columns.
-
-\item
-{\tt 'myfile.fits[EVENTS][PHA > 5]'}:  creates and opens a temporary FITS
-files that is identical to 'myfile.fits' except that the EVENTS table
-will only contain the rows that have values of the PHA column greater
-than 5.  In general, any arbitrary boolean expression using a C or
-Fortran-like syntax, which may combine AND and OR operators,
-may be used to select rows from a table.
-
-\item
-{\tt 'myfile.fits[EVENTS][bin (X,Y)=1,2048,4]'}:  creates a temporary FITS
-primary array image which is computed on the fly by binning (i.e,
-computing the 2-dimensional histogram) of the values in the X and Y
-columns of the EVENTS extension.  In this case the X and Y coordinates
-range from 1 to 2048 and the image pixel size is 4 units in both
-dimensions, so the resulting image is 512 x 512 pixels in size.
-
-\item
-The final example combines many of these feature into one complex
-expression (it is broken into several lines for clarity):
-
-\begin{verbatim}
-  'ftp://legacy.gsfc.nasa.gov/data/sample.fits.gz[EVENTS]
-   [col phacorr = pha * 1.1 - 0.3][phacorr >= 5.0 && phacorr <= 14.0]
-   [bin (X,Y)=32]'
-\end{verbatim}
-In this case, CFITSIO (1) copies and uncompresses the FITS file from
-the ftp site on the legacy machine, (2) moves to the 'EVENTS'
-extension, (3) calculates a new column called 'phacorr', (4) selects
-the rows in the table that have phacorr in the range 5 to 14, and
-finally (5) bins the remaining rows on the X and Y column coordinates,
-using a pixel size = 32 to create a 2D image.  All this processing is
-completely transparent to the application program, which simply sees
-the final 2-D image in the primary array of the opened file.
-\end{itemize}
-
-The full extended CFITSIO FITS file name can contain several different
-components depending on the context.  These components are described in
-the following sections:
-
-\begin{verbatim}
-When creating a new file:
-   filetype://BaseFilename(templateName)
-
-When opening an existing primary array or image HDU:
-   filetype://BaseFilename(outName)[HDUlocation][ImageSection]
-
-When opening an existing table HDU:
-   filetype://BaseFilename(outName)[HDUlocation][colFilter][rowFilter][binSpec]
-\end{verbatim}
-The filetype, BaseFilename, outName, HDUlocation, and ImageSection
-components, if present, must be given in that order, but the colFilter,
-rowFilter, and binSpec specifiers may follow in any order.  Regardless
-of the order, however, the colFilter specifier, if present, will be
-processed first by CFITSIO, followed by the rowFilter specifier, and
-finally by the binSpec specifier.
-
-
-\section{Filetype}
-
-The type of file determines the medium on which the file is located
-(e.g., disk or network) and, hence, which internal device driver is used by
-CFITSIO to read and/or write the file.  Currently supported types are
-
-\begin{verbatim}
-        file://  - file on local magnetic disk (default)
-        ftp://   - a readonly file accessed with the anonymous FTP protocol.
-                   It also supports  ftp://username:password@hostname/...
-                   for accessing password-protected ftp sites.
-        http://  - a readonly file accessed with the HTTP protocol.  It
-                   supports username:password just like the ftp driver.
-                   Proxy HTTP servers are supported using the http_proxy
-                   environment variable (see following note).
-      stream://  - special driver to read an input FITS file from the stdin
-                   stream, and/or write an output FITS file to the stdout
-		   stream.  This driver is fragile and has limited
-		   functionality (see the following note).
-      gsiftp://  - access files on a computational grid using the gridftp
-                   protocol in the Globus toolkit (see following note).
-        root://  - uses the CERN root protocol for writing as well as
-                   reading files over the network.
-        shmem:// - opens or creates a file which persists in the computer's
-                   shared memory.
-        mem://   - opens a temporary file in core memory.  The file
-                   disappears when the program exits so this is mainly
-                   useful for test purposes when a permanent output file
-                   is not desired.
-\end{verbatim}
-If the filetype is not specified, then type file:// is assumed.
-The double slashes '//' are optional and may be omitted in most cases.

-\subsection{Notes about HTTP proxy servers}
-
-A proxy HTTP server may be used by defining the address (URL) and port
-number of the proxy server with the http\_proxy environment variable.
-For example
-
-\begin{verbatim}
-    setenv http_proxy http://heasarc.gsfc.nasa.gov:3128
-\end{verbatim}
-will cause CFITSIO to use port 3128 on the heasarc proxy server whenever
-reading a FITS file with HTTP.
-
-
-\subsection{Notes about the stream filetype driver}
-
-The stream driver can be used to efficiently read a FITS file from the stdin
-file stream or write a FITS to the stdout file stream.  However, because these
-input and output streams must be accessed sequentially, the FITS file reading or
-writing application must also read and write the file sequentially, at least
-within the tolerances described below.
-
-CFITSIO supports 2 different methods for accessing FITS files on the stdin and
-stdout streams.  The original method, which is invoked by specifying a dash
-character, "-", as the name of the file when opening or creating it, works by
-storing a complete copy of the entire FITS file in memory.  In this case, when
-reading from stdin, CFITSIO will copy the entire stream into memory before doing
-any processing of the file.  Similarly, when writing to stdout, CFITSIO will
-create a copy of the entire FITS file in memory, before finally flushing it out
-to  the stdout stream when the FITS file is closed.  Buffering the entire FITS
-file in this way allows the application to randomly access any part of the FITS
-file, in any order, but it also requires that the user have sufficient available
-memory (or virtual memory) to store the entire file, which may not be possible
-in the case of very large files.
-
-The newer stream filetype provides a more memory-efficient method of accessing
-FITS files on the stdin or stdout streams.  Instead of storing a copy of the
-entire FITS file in memory, CFITSIO only uses a set of internal  buffer which by
-default can store  40 FITS blocks, or about  100K bytes of the FITS file.  The
-application program must process the FITS file sequentially from beginning to
-end, within this 100K buffer.  Generally speaking the application  program must
-conform to the following restrictions:
-
-\begin{itemize}
-\item
-The program must finish reading or writing the header keywords
-before reading or writing any data in the HDU.
-\item
-The HDU can contain at most about 1400 header keywords.  This is the
-maximum that can fit in the nominal 40 FITS block buffer.  In principle,
-this limit could be increased by recompiling CFITSIO with a larger
-buffer limit, which is set by the NIOBUF parameter in fitsio2.h.
-\item
-The program must read or write the data in a sequential manner from the
-beginning to the end of the HDU.  Note that CFITSIO's internal
-100K buffer allows a little latitude in meeting this requirement.
-\item
-The program cannot move back to a previous HDU in the FITS file.
-\item
-Reading or writing of variable length array columns in binary tables is not
-supported on streams, because this requires moving back and forth between the
-fixed-length portion of the binary table and the following heap area where the
-arrays are actually stored.
-\item
-Reading or writing of tile-compressed images is not supported on streams,
-because the images are internally stored using variable length arrays.
-\end{itemize}
-
-
-\subsection{Notes about the gsiftp filetype}
-
-DEPENDENCIES: Globus toolkit (2.4.3 or higher) (GT) should be installed.
-There are two different ways to install GT:
-
-1) goto the globus toolkit web page www.globus.org and follow the
-   download and compilation instructions;
-
-2) goto the Virtual Data Toolkit web page http://vdt.cs.wisc.edu/
-   and follow the instructions (STRONGLY SUGGESTED);
-
-Once a globus client has been installed in your system with a specific flavour
-it is possible to compile and install the CFITSIO libraries.
-Specific configuration flags must be used:
-
-1)  --with-gsiftp[[=PATH]] Enable Globus Toolkit gsiftp protocol support
-    PATH=GLOBUS\_LOCATION i.e. the location of your globus installation
-
-2)  --with-gsiftp-flavour[[=PATH] defines the specific Globus flavour
-        ex. gcc32
-
-Both the flags must be used and it is mandatory to set  both the PATH and the
-flavour.
-
-USAGE: To access files on a gridftp server it is necessary to use a gsiftp prefix:
-
-example: gsiftp://remote\_server\_fqhn/directory/filename
-
-The gridftp driver uses a local buffer on a temporary file the file is located
-in the /tmp directory. If you have special permissions on /tmp or you do not have a /tmp
-directory, it is possible to force another location setting the GSIFTP\_TMPFILE environment
-variable (ex. export GSIFTP\_TMPFILE=/your/location/yourtmpfile).
-
-Grid FTP supports multi channel transfer. By default a single channel transmission is
-available. However, it is possible to modify this behavior setting the GSIFTP\_STREAMS
-environment variable (ex. export GSIFTP\_STREAMS=8).
-
-
-\subsection{Notes about the root filetype}
-
-The original rootd server can be obtained from:
-\verb-ftp://root.cern.ch/root/rootd.tar.gz-
-but, for it to work correctly with CFITSIO one has to use a modified
-version which supports a command to return the length of the file.
-This modified version is available in rootd subdirectory
-in the CFITSIO ftp area at
-
-\begin{verbatim}
-      ftp://legacy.gsfc.nasa.gov/software/fitsio/c/root/rootd.tar.gz.
-\end{verbatim}
-
-This small server is started either by inetd when a client requests a
-connection to a rootd server or by hand (i.e. from the command line).
-The rootd server works with the ROOT TNetFile class. It allows remote
-access to ROOT database files in either read or write mode. By default
-TNetFile assumes port 432 (which requires rootd to be started as root).
-To run rootd via inetd add the following line to /etc/services:
-
-\begin{verbatim}
-  rootd     432/tcp
-\end{verbatim}
-and to /etc/inetd.conf, add the following line:
-
-\begin{verbatim}
-  rootd stream tcp nowait root /user/rdm/root/bin/rootd rootd -i
-\end{verbatim}
-Force inetd to reread its conf file with "kill -HUP <pid inetd>".
-You can also start rootd by hand running directly under your private
-account (no root system privileges needed). For example to start
-rootd listening on port 5151 just type:   \verb+rootd -p 5151+
-Notice: no \& is needed. Rootd will go into background by itself.
-
-\begin{verbatim}
-  Rootd arguments:
-    -i                says we were started by inetd
-    -p port#          specifies a different port to listen on
-    -d level          level of debug info written to syslog
-                      0 = no debug (default)
-                      1 = minimum
-                      2 = medium
-                      3 = maximum
-\end{verbatim}
-Rootd can also be configured for anonymous usage (like anonymous ftp).
-To setup rootd to accept anonymous logins do the following (while being
-logged in as root):
-
-\begin{verbatim}
-   - Add the following line to /etc/passwd:
-
-     rootd:*:71:72:Anonymous rootd:/var/spool/rootd:/bin/false
-
-     where you may modify the uid, gid (71, 72) and the home directory
-     to suite your system.
-
-   - Add the following line to /etc/group:
-
-     rootd:*:72:rootd
-
-     where the gid must match the gid in /etc/passwd.
-
-   - Create the directories:
-
-     mkdir /var/spool/rootd
-     mkdir /var/spool/rootd/tmp
-     chmod 777 /var/spool/rootd/tmp
-
-     Where /var/spool/rootd must match the rootd home directory as
-     specified in the rootd /etc/passwd entry.
-
-   - To make writeable directories for anonymous do, for example:
-
-     mkdir /var/spool/rootd/pub
-     chown rootd:rootd /var/spool/rootd/pub
-\end{verbatim}
-That's all.  Several additional remarks:  you can login to an anonymous
-server either with the names "anonymous" or "rootd".  The password should
-be of type user@host.do.main. Only the @ is enforced for the time
-being.  In anonymous mode the top of the file tree is set to the rootd
-home directory, therefore only files below the home directory can be
-accessed.  Anonymous mode only works when the server is started via
-inetd.
-
-
-\subsection{Notes about the shmem filetype:}
-
-Shared memory files are currently supported on most Unix platforms,
-where the shared memory segments are managed by the operating system
-kernel and `live' independently of processes. They are not deleted (by
-default) when the process which created them terminates, although they
-will disappear if the system is rebooted.  Applications can create
-shared memory files in CFITSIO by calling:
-
-\begin{verbatim}
-   fit_create_file(&fitsfileptr, "shmem://h2", &status);
-\end{verbatim}
-where the root `file' names are currently restricted to be 'h0', 'h1',
-'h2', 'h3', etc., up to a maximum number defined by the the value of
-SHARED\_MAXSEG (equal to 16 by default).  This is a prototype
-implementation of the shared memory interface and a more robust
-interface, which will have fewer restrictions on the number of files
-and on their names, may be developed in the future.
-
-When opening an already existing FITS file in shared memory one calls
-the usual CFITSIO routine:
-
-\begin{verbatim}
-   fits_open_file(&fitsfileptr, "shmem://h7", mode, &status)
-\end{verbatim}
-The file mode can be READWRITE or READONLY just as with disk files.
-More than one process can operate on READONLY mode files at the same
-time.  CFITSIO supports proper file locking (both in READONLY and
-READWRITE modes), so calls to fits\_open\_file may be locked out until
-another other process closes the file.
-
-When an application is finished accessing a FITS file in a shared
-memory segment, it may close it  (and the file will remain in the
-system) with fits\_close\_file, or delete it with fits\_delete\_file.
-Physical deletion is postponed until the last process calls
-ffclos/ffdelt.  fits\_delete\_file tries to obtain a READWRITE lock on
-the file to be deleted, thus it can be blocked if the object was not
-opened in READWRITE mode.
-
-A shared memory management utility program called `smem', is included
-with the CFITSIO distribution.  It can be built by typing `make smem';
-then type `smem -h' to get a list of valid options.  Executing smem
-without any options causes it to list all the shared memory segments
-currently residing in the system and managed by the shared memory
-driver. To get a list of all the shared memory objects, run the system
-utility program `ipcs  [-a]'.
-
-
-\section{Base Filename}
-
-The base filename is the name of the file optionally including the
-director/subdirectory path, and in the case of `ftp', `http', and `root'
-filetypes, the machine identifier.  Examples:
-
-\begin{verbatim}
-    myfile.fits
-    !data.fits
-    /data/myfile.fits
-    fits.gsfc.nasa.gov/ftp/sampledata/myfile.fits.gz
-\end{verbatim}
-
-When creating a new output file on magnetic disk (of type file://) if
-the base filename begins with an exclamation point (!) then any
-existing file with that same basename will be deleted prior to creating
-the new FITS file.  Otherwise if the file to be created already exists,
-then CFITSIO will return an error and will not overwrite the existing
-file.  Note  that the exclamation point,  '!', is a special UNIX character,
-so if it is used  on the command line rather than entered at a task
-prompt, it must be  preceded by a backslash to force the UNIX
-shell to pass it verbatim to the application program.
-
-If the output disk file name ends with the suffix '.gz', then CFITSIO
-will compress the file using the gzip compression algorithm before
-writing it to disk.  This can reduce the amount of disk space used by
-the file.  Note that this feature requires that the uncompressed file
-be constructed in memory before it is compressed and written to disk,
-so it can fail if there is insufficient available memory.
-
-An input FITS file may be compressed with the gzip or Unix compress
-algorithms, in which case CFITSIO will uncompress the file on the fly
-into a temporary file (in memory or on disk).  Compressed files may
-only be opened with read-only permission.  When specifying the name of
-a compressed FITS file it is not necessary to append the file suffix
-(e.g., `.gz' or `.Z').  If CFITSIO cannot find the input file name
-without the suffix, then it will automatically search for a compressed
-file with the same root name.  In the case of reading ftp and http type
-files, CFITSIO generally looks for a compressed version of the file
-first, before trying to open the uncompressed file.  By default,
-CFITSIO copies (and uncompressed if necessary) the ftp or http FITS
-file into memory on the local machine before opening it.  This will
-fail if the local machine does not have enough memory to hold the whole
-FITS file, so in this case, the output filename specifier (see the next
-section) can be used to further control how CFITSIO reads ftp and http
-files.
-
-If the input file is an IRAF image file (*.imh file) then CFITSIO will
-automatically convert it on the fly into a virtual FITS image before it
-is opened by the application program.  IRAF images can only be opened
-with READONLY file access.
-
-Similarly, if the input file is a raw binary data array, then CFITSIO
-will convert it on the fly into a virtual FITS image with the basic set
-of required header keywords before it is opened by the application
-program (with READONLY access).  In this case the data type and
-dimensions of the image must be specified in square brackets following
-the filename (e.g. rawfile.dat[ib512,512]). The first character (case
-insensitive) defines the datatype of the array:
-
-\begin{verbatim}
-     b         8-bit unsigned byte
-     i        16-bit signed integer
-     u        16-bit unsigned integer
-     j        32-bit signed integer
-     r or f   32-bit floating point
-     d        64-bit floating point
-\end{verbatim}
-An optional second character specifies the byte order of the array
-values: b or B indicates big endian (as in FITS files and the native
-format of SUN UNIX workstations and Mac PCs) and l or L indicates
-little endian (native format of DEC OSF workstations and IBM PCs).  If
-this character is omitted then the array is assumed to have the native
-byte order of the local machine.  These datatype characters are then
-followed by a series of one or more integer values separated by commas
-which define the size of each dimension of the raw array.  Arrays with
-up to 5 dimensions are currently supported.  Finally, a byte offset to
-the position of the first pixel in the data file may be specified by
-separating it with a ':' from the last dimension value.  If omitted, it
-is assumed that the offset = 0.  This parameter may be used to skip
-over any header information in the file that precedes the binary data.
-Further examples:
-
-\begin{verbatim}
-  raw.dat[b10000]           1-dimensional 10000 pixel byte array
-  raw.dat[rb400,400,12]     3-dimensional floating point big-endian array
-  img.fits[ib512,512:2880]  reads the 512 x 512 short integer array in
-                            a FITS file, skipping over the 2880 byte header
-\end{verbatim}
-
-One special case of input file is where the filename = `-' (a dash or
-minus sign) or 'stdin' or 'stdout', which signifies that the input file
-is to be read from the stdin stream, or written to the stdout stream if
-a new output file is being created.  In the case of reading from stdin,
-CFITSIO first copies the whole stream into a temporary FITS file (in
-memory or on disk), and subsequent reading of the FITS file occurs in
-this copy.  When writing to stdout, CFITSIO first constructs the whole
-file in memory (since random access is required), then flushes it out
-to the stdout stream when the file is closed.   In addition, if the
-output filename = '-.gz' or 'stdout.gz' then it will be gzip compressed
-before being written to stdout.
-
-This ability to read and write on the stdin and stdout steams allows
-FITS files to be piped between tasks in memory rather than having to
-create temporary intermediate FITS files on disk.  For example if task1
-creates an output FITS file, and task2 reads an input FITS file, the
-FITS file may be piped between the 2 tasks by specifying
-
-\begin{verbatim}
-   task1 - | task2 -
-\end{verbatim}
-where the vertical bar is the Unix piping symbol.  This assumes that the 2
-tasks read the name of the FITS file off of the command line.
-
-
-\section{Output File Name when Opening an Existing File}
-
-An optional output filename may be specified in parentheses immediately
-following the base file name to be opened.  This is mainly useful in
-those cases where CFITSIO creates a temporary copy of the input FITS
-file before it is opened and passed to the application program.  This
-happens by default when opening a network FTP or HTTP-type file, when
-reading a compressed FITS file on a local disk, when reading from the
-stdin stream, or when a column filter, row filter, or binning specifier
-is included as part of the input file specification.  By default this
-temporary file is created in memory.  If there is not enough memory to
-create the file copy, then CFITSIO will exit with an error.   In these
-cases one can force a permanent file to be created on disk, instead of
-a temporary file in memory, by supplying the name in parentheses
-immediately following the base file name.  The output filename can
-include the '!' clobber flag.
-
-Thus, if the input filename to CFITSIO is:
-\verb+file1.fits.gz(file2.fits)+
-then CFITSIO will uncompress `file1.fits.gz' into the local disk file
-`file2.fits' before opening it.  CFITSIO does not automatically delete
-the output file, so it will still exist after the application program
-exits.
-
-In some cases, several different temporary FITS files will be created
-in sequence, for instance, if one opens a remote file using FTP, then
-filters rows in a binary table extension, then create an image by
-binning a pair of columns.  In this case, the remote file will be
-copied to a temporary local file, then a second temporary file will be
-created containing the filtered rows of the table, and finally a third
-temporary file containing the binned image will be created.  In cases
-like this where multiple files are created, the outfile specifier will
-be interpreted the name of the final file as described below, in descending
-priority:
-
-\begin{itemize}
-\item
-as the name of the final image file if an image within a single binary
-table cell is opened or if an image is created by binning a table column.
-\item
-as the name of the file containing the filtered table if a column filter
-and/or a row filter are specified.
-\item
-as the name of the local copy of the remote FTP or HTTP file.
-\item
-as the name of the uncompressed version of the FITS file, if a
-compressed FITS file on local disk has been opened.
-\item
-otherwise, the output filename is ignored.
-\end{itemize}
-
-
-The output file specifier is useful when reading FTP or HTTP-type
-FITS files since it can be used to create a local disk copy of the file
-that can be reused in the future.  If the output file name = `*' then a
-local file with the same name as the network file will be created.
-Note that CFITSIO will behave differently depending on whether the
-remote file is compressed or not as shown by the following examples:
-\begin{itemize}
-\item
-`ftp://remote.machine/tmp/myfile.fits.gz(*)' - the remote compressed
-file is copied to the local compressed file `myfile.fits.gz', which
-is then uncompressed in local memory before being opened and passed
-to the application program.
-
-\item
-`ftp://remote.machine/tmp/myfile.fits.gz(myfile.fits)' - the remote
-compressed file is copied and uncompressed into the local file
-`myfile.fits'.  This example requires less local memory than the
-previous example since the file is uncompressed on disk instead of
-in memory.
-
-\item
-`ftp://remote.machine/tmp/myfile.fits(myfile.fits.gz)' - this will
-usually produce an error since CFITSIO itself cannot compress files.
-\end{itemize}
-
-The exact behavior of CFITSIO in the latter case depends on the type of
-ftp server running on the remote machine and how it is configured.  In
-some cases, if the file `myfile.fits.gz' exists on the remote machine,
-then the server will copy it to the local machine.  In other cases the
-ftp server will automatically create and transmit a compressed version
-of the file if only the uncompressed version exists.  This can get
-rather confusing, so users should use a certain amount of caution when
-using the output file specifier with FTP or HTTP file types, to make
-sure they get the behavior that they expect.
-
-
-\section{Template File Name when Creating a New File}
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described below.
-
-
-\section{Image Tile-Compression Specification}
-
-When specifying the name of the output FITS file to be created, the
-user can indicate that images should be written in tile-compressed
-format (see section 5.5, ``Primary Array or IMAGE Extension I/O
-Routines'') by enclosing the compression parameters in square brackets
-following the root disk file name.  Here are some examples of the
-syntax for specifying tile-compressed output images:
-
-\begin{verbatim}
-    myfile.fit[compress]    - use Rice algorithm and default tile size
-
-    myfile.fit[compress GZIP] - use the specified compression algorithm;
-    myfile.fit[compress Rice]     only the first letter of the algorithm
-    myfile.fit[compress PLIO]     name is required.
-
-    myfile.fit[compress Rice 100,100]   - use 100 x 100 pixel tile size
-    myfile.fit[compress Rice 100,100;2] - as above, and use noisebits = 2
-\end{verbatim}
-
-
-\section{HDU Location Specification}
-
-The optional HDU location specifier defines which HDU (Header-Data
-Unit, also known as an `extension') within the FITS file to initially
-open.  It must immediately follow the base file name (or the output
-file name if present).  If it is not specified then the first HDU (the
-primary array) is opened.  The HDU location specifier is required if
-the colFilter, rowFilter, or binSpec specifiers are present, because
-the primary array is not a valid HDU for these operations. The HDU may
-be specified either by absolute position number, starting with 0 for
-the primary array, or by reference to the HDU name, and optionally, the
-version number and the HDU type of the desired extension.  The location
-of an image within a single cell of a binary table may also be
-specified, as described below.
-
-The absolute position of the extension is specified either by enclosed
-the number in square brackets (e.g., `[1]' = the first extension
-following the primary array) or by preceded the number with a plus sign
-(`+1').  To specify the HDU by name, give the name of the desired HDU
-(the value of the EXTNAME or HDUNAME keyword) and optionally the
-extension version number (value of the EXTVER keyword) and the
-extension type (value of the XTENSION keyword: IMAGE, ASCII or TABLE,
-or BINTABLE), separated by commas and all enclosed in square brackets.
-If the value of EXTVER and XTENSION are not specified, then the first
-extension with the correct value of EXTNAME is opened. The extension
-name and type are not case sensitive, and the extension type may be
-abbreviated to a single letter (e.g., I = IMAGE extension or primary
-array, A or T = ASCII table extension, and B = binary table BINTABLE
-extension).   If the HDU location specifier is equal to `[PRIMARY]' or
-`[P]', then the primary array (the first HDU) will be opened.
-
-FITS images are most commonly stored in the primary array or an image
-extension, but images can also be stored as a vector in a single cell
-of a binary table (i.e. each row of the vector column contains a
-different image).  Such an image can be opened with CFITSIO by
-specifying the desired column  name and the row number after the binary
-table HDU specifier as shown in the following examples. The column name
-is separated from the HDU specifier by a semicolon and the row number
-is enclosed in parentheses.  In this case CFITSIO copies the image from
-the table cell into a temporary primary array before it is opened.  The
-application program then just sees the image in the primary array,
-without any extensions.  The particular row to be opened may be
-specified either by giving an absolute integer row number (starting
-with 1 for the first row), or by specifying a boolean expression that
-evaluates to TRUE for the desired row.  The first row that satisfies
-the expression will be used.  The row selection expression has the same
-syntax as described in the Row Filter Specifier section, below.
-
- Examples:
-
-\begin{verbatim}
-   myfile.fits[3] - open the 3rd HDU following the primary array
-   myfile.fits+3  - same as above, but using the FTOOLS-style notation
-   myfile.fits[EVENTS] - open the extension that has EXTNAME = 'EVENTS'
-   myfile.fits[EVENTS, 2]  - same as above, but also requires EXTVER = 2
-   myfile.fits[events,2,b] - same, but also requires XTENSION = 'BINTABLE'
-   myfile.fits[3; images(17)] - opens the image in row 17 of the 'images'
-                                column in the 3rd extension of the file.

-\section{Image Section}
-
-A virtual file containing a rectangular subsection of an image can be
-extracted and opened by specifying the range of pixels (start:end)
-along each axis to be extracted from the original image.  One can also
-specify an optional pixel increment (start:end:step) for each axis of
-the input image.  A pixel step = 1 will be assumed if it is not
-specified.  If the start pixel is larger then the end pixel, then the
-image will be flipped (producing a mirror image) along that dimension.
-An asterisk, '*', may be used to specify the entire range of an axis,
-and '-*' will flip the entire axis. The input image can be in the
-primary array, in an image extension, or contained in a vector cell of
-a binary table. In the later 2 cases the extension name or number must
-be specified before the image section specifier.
-
- Examples:
-
-\begin{verbatim}
-  myfile.fits[1:512:2, 2:512:2] -  open a 256x256 pixel image
-              consisting of the odd numbered columns (1st axis) and
-              the even numbered rows (2nd axis) of the image in the
-              primary array of the file.
-
-  myfile.fits[*, 512:256] - open an image consisting of all the columns
-              in the input image, but only rows 256 through 512.
-              The image will be flipped along the 2nd axis since
-              the starting pixel is greater than the ending pixel.
-
-  myfile.fits[*:2, 512:256:2] - same as above but keeping only
-              every other row and column in the input image.
-
-  myfile.fits[-*, *] - copy the entire image, flipping it along
-              the first axis.
-
-  myfile.fits[3][1:256,1:256] - opens a subsection of the image that
-              is in the 3rd extension of the file.
-
-  myfile.fits[4; images(12)][1:10,1:10] - open an image consisting
-	      of the first 10 pixels in both dimensions. The original
-	      image resides in the 12th row of the 'images' vector
-	      column in the table in the 4th extension of the file.
-\end{verbatim}
-
-When CFITSIO opens an image section it first creates a temporary file
-containing the image section plus a copy of any other HDUs in the
-file.  This temporary file is then opened by the application program,
-so it is not possible to write to or modify the input file when
-specifying an image section.  Note that CFITSIO automatically updates
-the world coordinate system keywords in the header of the image
-section, if they exist, so that the coordinate associated with each
-pixel in the image section will be computed correctly.
-
-
-\section{Image Transform Filters}
-
-CFITSIO can apply a user-specified mathematical function to the value
-of every pixel in a FITS image, thus creating a new virtual image
-in computer memory that is then opened and read by the application
-program.  The original FITS image is not modified by this process.
-
-The image transformation specifier is appended to the input
-FITS file name and is enclosed in square brackets.  It begins with the
-letters 'PIX' to distinguish it from other types of FITS file filters
-that are recognized by CFITSIO.  The image transforming function may
-use any of the mathematical operators listed in the following
-'Row Filtering Specification' section of this document.
-Some examples of  image transform filters are:
-
-\begin{verbatim}
- [pix X * 2.0]               - multiply each pixel by 2.0
- [pix sqrt(X)]               - take the square root of each pixel
- [pix X + #ZEROPT            - add the value of the ZEROPT keyword
- [pix X>0 ? log10(X) : -99.] - if the pixel value is greater
-                               than 0, compute the base 10 log,
-                               else set the pixel = -99.
-\end{verbatim}
-Use the letter 'X' in the expression to represent the current pixel value
-in the image.  The expression is evaluated
-independently for each pixel in the image and may be a function of 1) the
-original pixel value, 2) the value of other pixels in the image at
-a given relative offset from the position of the pixel that is being
-evaluated, and 3) the value of
-any header keywords.  Header keyword values are represented
-by the name of the keyword preceded by the '\#' sign.
-
-
-To access the the value of adjacent pixels in the image,
-specify the (1-D) offset from the current pixel in curly brackets.
-For example
-
-\begin{verbatim}
- [pix  (x{-1} + x + x{+1}) / 3]
-\end{verbatim}
-will replace each pixel value with the running mean of the values of that
-pixel and it's 2 neighboring pixels.  Note that in this notation the image
-is treated as a 1-D array, where each row of the image (or higher dimensional
-cube) is appended one after another in one long array of pixels.
-It is possible to refer to pixels
-in the rows above or below the current pixel by using the value of the
-NAXIS1 header keyword.  For example
-
-\begin{verbatim}
- [pix (x{-#NAXIS1} + x + x{#NAXIS1}) / 3]
-\end{verbatim}
-will compute the mean of each image pixel and the pixels immediately
-above and below it in the adjacent rows of the image.
-The following more complex example
-creates a smoothed virtual image where each pixel
-is a 3 x 3 boxcar average of the input image pixels:
-
-\begin{verbatim}
-  [pix (X + X{-1} + X{+1}
-      + X{-#NAXIS1} + X{-#NAXIS1 - 1} + X{-#NAXIS1 + 1}
-      + X{#NAXIS1} + X{#NAXIS1 - 1} + X{#NAXIS1 + 1}) / 9.]
-\end{verbatim}
-If the pixel offset
-extends beyond the first or last pixel in the image, the function will
-evaluate to undefined, or NULL.
-
-For  complex  or commonly used image filtering operations,
-one  can  write the expression into an external text  file and
-then import it  into the
-filter using  the syntax '[pix @filename.txt]'.   The mathematical
-expression can
-extend over multiple lines of text in the  file.
-Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-By default, the datatype of the resulting image will be the same as
-the original image, but one may force a different datatype by appended
-a code letter to the 'pix' keyword:
-
-\begin{verbatim}
-      pixb  -  8-bit byte    image with BITPIX =   8
-      pixi  - 16-bit integer image with BITPIX =  16
-      pixj  - 32-bit integer image with BITPIX =  32
-      pixr  - 32-bit float   image with BITPIX = -32
-      pixd  - 64-bit float   image with BITPIX = -64
-\end{verbatim}
-Also by default, any other HDUs in the input file will be copied without
-change to the
-output virtual FITS file, but one may discard the other HDUs by adding
-the number '1' to the 'pix' keyword (and following any optional datatype code
-letter).  For example:
-
-\begin{verbatim}
-     myfile.fits[3][pixr1  sqrt(X)]
-\end{verbatim}
-will create a virtual FITS file containing only a primary array image
-with 32-bit floating point pixels that have a value equal to the square
-root of the pixels in the image that is in the 3rd extension
-of the 'myfile.fits' file.
-
-
-
-
-\section{Column and Keyword Filtering Specification}
-
-The optional column/keyword filtering specifier is used to modify the
-column structure and/or the header keywords in the HDU that was
-selected with the previous HDU location specifier. This filtering
-specifier must be enclosed in square brackets and can be distinguished
-from a general row filter specifier (described below) by the fact that
-it begins with the string 'col ' and is not immediately followed by an
-equals sign.  The original file is not changed by this filtering
-operation, and instead the modifications are made on a copy of the
-input FITS file (usually in memory), which also contains a copy of all
-the other HDUs in the file.  This temporary file is passed to the
-application program and will persist only until the file is closed or
-until the program exits, unless the outfile specifier (see above) is
-also supplied.
-
-The column/keyword filter can be used to perform the following
-operations.  More than one operation may be specified by separating
-them with commas or semi-colons.
-
-\begin{itemize}
-
-\item
-Copy only a specified list of columns columns to the filtered input file.
-The list of column name should be separated by semi-colons.  Wild card
-characters may be used in the column names to match multiple columns.
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table
-except the explicitly deleted columns will appear in the filtered
-table (i.e., there is no need to explicitly list the columns to
-be included if any columns are being deleted).
-
-\item
-Delete a column or keyword by listing the name preceded by a minus
-sign or an exclamation mark (!), e.g., '-TIME' will delete the TIME
-column if it exists, otherwise the TIME keyword.  An error is returned
-if neither a column nor keyword with this name exists.  Note  that the
-exclamation point,  '!', is a special UNIX character, so if it is used
-on the command line rather than entered at a task prompt, it must be
-preceded by a backslash to force the UNIX shell to ignore it.
-
-\item
-Rename an existing column or keyword with the syntax 'NewName ==
-OldName'.  An error is returned if neither a column nor keyword with
-this name exists.
-
-\item
-Append a new column or keyword to the table.  To create a column,
-give the new name, optionally followed by the datatype in parentheses,
-followed by a single equals sign and an  expression to be used to
-compute the value (e.g., 'newcol(1J) = 0' will create a new 32-bit
-integer column called 'newcol' filled with zeros).  The datatype is
-specified using the same syntax that is allowed for the value of the
-FITS TFORMn keyword (e.g., 'I', 'J', 'E', 'D', etc. for binary tables,
-and 'I8', F12.3', 'E20.12', etc. for ASCII tables).  If the datatype is
-not specified then an appropriate datatype will be chosen depending on
-the form of the expression (may be a character string, logical, bit, long
-integer, or double column). An appropriate vector count (in the case
-of binary tables) will also be added if not explicitly specified.
-
-When creating a new keyword, the keyword name must be preceded by a
-pound sign '\#', and the expression must evaluate to a scalar
-(i.e., cannot have a column name in the expression).  The comment
-string for the keyword may be specified in parentheses immediately
-following the keyword name (instead of supplying a datatype as in
-the case of creating a new column).  If the keyword name ends with a
-pound sign '\#', then cfitsio will substitute the number of the
-most recently referenced column for the \# character .
-This is especially useful when writing
-a column-related keyword like TUNITn for a newly created column,
-as shown in the following examples.
-
-\item
-Recompute (overwrite) the values in an existing column or keyword by
-giving the name followed by an equals sign and an arithmetic
-expression.
-\end{itemize}
-
-The expression that is used when appending or recomputing columns or
-keywords can be arbitrarily complex and may be a function of other
-header keyword values and other columns (in the same row).  The full
-syntax and available functions for the expression are described below
-in the row filter specification section.
-
-If the expression contains both a list of columns to be included and
-columns to be deleted, then all the columns in the original table
-except the explicitly deleted columns will appear in the filtered
-table.  If no columns to be deleted are specified, then only the
-columns that are explicitly listed will be included in the filtered
-output table.  To include all the columns, add the '*' wildcard
-specifier at the end of the list, as shown in the examples.
-
-For  complex  or commonly used operations,  one  can also  place the
-operations into an external text  file and import it  into the  column
-filter using  the syntax '[col @filename.txt]'.   The operations can
-extend over multiple lines of the  file, but multiple operations must
-still be separated by semicolons.   Any lines in the external text file
-that begin with 2 slash characters ('//') will be ignored and may be
-used to add comments into the file.
-
-Examples:
-
-\begin{verbatim}
-   [col Time; rate]              - only the Time and rate columns will
-                                   appear in the filtered input file.
-
-   [col Time, *raw]              - include the Time column and any other
-                                   columns whose name ends with 'raw'.
-
-   [col -TIME; Good == STATUS]   - deletes the TIME column and
-                                   renames the status column to 'Good'
-
-   [col PI=PHA * 1.1 + 0.2; #TUNIT#(column units) = 'counts';*]
-                                 - creates new PI column from PHA values
-                                   and also writes the TUNITn keyword
-                                   for the new column.  The final '*'
-                                   expression means preserve all the
-                                   columns in the input table in the
-                                   virtual output table;  without the '*'
-                                   the output table would only contain
-                                   the single 'PI' column.
-
-   [col rate = rate/exposure; TUNIT#(&) = 'counts/s';*]
-                                 - recomputes the rate column by dividing
-                                   it by the EXPOSURE keyword value. This
-                                   also modifies the value of the TUNITn
-                                   keyword for this column. The use of the
-                                   '&' character for the keyword comment
-                                   string means preserve the existing
-                                   comment string for that keyword. The
-                                   final '*' preserves all the columns
-                                   in the input table in the virtual
-                                   output table.
-\end{verbatim}
-
-
-\section{Row Filtering Specification}
-
-    When entering the name of a FITS table that is to be opened by a
-    program, an optional row filter may be specified to select a subset
-    of the rows in the table.  A temporary new FITS file is created on
-    the fly which contains only those rows for which the row filter
-    expression evaluates to true.  (The primary array and any other
-    extensions in the input file are also copied to the temporary
-    file).  The original FITS file is closed and the new virtual file
-    is opened by the application program.  The row filter expression is
-    enclosed in square brackets following the file name and extension
-    name (e.g., 'file.fits[events][GRADE==50]'  selects only those rows
-    where the GRADE column value equals 50).   When dealing with tables
-    where each row has an associated time and/or 2D spatial position,
-    the row filter expression can also be used to select rows based on
-    the times in a Good Time Intervals (GTI) extension, or on spatial
-    position as given in a SAO-style region file.
-
-
-\subsection{General Syntax}
-
-    The row filtering  expression can be an arbitrarily  complex series
-    of operations performed  on constants,  keyword values,  and column
-    data taken from the specified FITS TABLE extension.  The expression
-    must evaluate to a boolean  value for each row  of the table, where
-    a value of FALSE means that the row will be excluded.
-
-    For complex or commonly  used filters, one can place the expression
-    into a text file and import it into the row filter using the syntax
-    '[@filename.txt]'.  The expression can be  arbitrarily complex and
-    extend over multiple lines of the file.  Any lines in the external
-    text file that begin with 2 slash characters ('//') will be ignored
-    and may be used to add comments into the file.
-
-    Keyword and   column data  are referenced by   name.  Any  string of
-    characters not surrounded by    quotes (ie, a constant  string)   or
-    followed by   an open parentheses (ie,   a  function name)   will be
-    initially interpreted   as a column  name and  its contents for the
-    current row inserted into the expression.  If no such column exists,
-    a keyword of that  name will be searched for  and its value used, if
-    found.  To force the  name to be  interpreted as a keyword (in case
-    there is both a column and keyword with the  same name), precede the
-    keyword name with a single pound sign, '\#', as in '\#NAXIS2'.  Due to
-    the generalities of FITS column and  keyword names, if the column or
-    keyword name  contains a space or a  character which might appear as
-    an arithmetic  term then enclose  the  name in '\$'  characters as in
-    \$MAX PHA\$ or \#\$MAX-PHA\$.  Names are case insensitive.
-
-    To access a table entry in a row other  than the current one, follow
-    the  column's name  with  a row  offset  within  curly  braces.  For
-    example, 'PHA\{-3\}' will evaluate to the value  of column PHA, 3 rows
-    above  the  row currently  being processed.   One  cannot specify an
-    absolute row number, only a relative offset.  Rows that fall outside
-    the table will be treated as undefined, or NULLs.
-
-    Boolean   operators can be  used in  the expression  in either their
-    Fortran or C forms.  The following boolean operators are available:
-
-\begin{verbatim}
-    "equal"         .eq. .EQ. ==  "not equal"          .ne.  .NE.  !=
-    "less than"     .lt. .LT. <   "less than/equal"    .le.  .LE.  <= =<
-    "greater than"  .gt. .GT. >   "greater than/equal" .ge.  .GE.  >= =>
-    "or"            .or. .OR. ||  "and"                .and. .AND. &&
-    "negation"     .not. .NOT. !  "approx. equal(1e-7)"  ~
-\end{verbatim}
-
-Note  that the exclamation
-point,  '!', is a special UNIX character, so if it is used  on the
-command line rather than entered at a task prompt, it must be  preceded
-by a backslash to force the UNIX shell to ignore it.
-
-    The expression may  also include arithmetic operators and functions.
-    Trigonometric  functions use  radians,  not degrees.  The  following
-    arithmetic  operators and  functions  can be  used in the expression
-    (function names are case insensitive). A null value will be returned
-    in case of illegal operations such as divide by zero, sqrt(negative)
-    log(negative), log10(negative), arccos(.gt. 1), arcsin(.gt. 1).
-

-    "substring"      strmid(s,p,n) "string search"         strstr(s,r)
-\end{verbatim}
-Three different random number functions are provided:  random(), with no
-arguments, produces a uniform random deviate between 0 and 1; randomn(),
-also with no arguments, produces a normal (Gaussian) random deviate  with
-zero mean and unit standard deviation; randomp(x) produces a Poisson random
-deviate whose expected number of counts is X.  X may be any positive real
-number of expected counts, including fractional values, but the return value
-is an integer.
-
-When the random functions are used in a vector expression, by default
-the same random value will be used when evaluating each element of the vector.
-If different random numbers are desired, then the name of a vector
-column should be supplied as the single argument to the random
-function (e.g., "flux + 0.1 * random(flux)", where "flux' is the
-name of a vector column).  This will create a vector of
-random numbers that will be used in sequence when evaluating each
-element of the vector expression.
-
-    An alternate syntax for the min and max functions  has only a single
-    argument which  should be  a  vector value (see  below).  The result
-    will be the minimum/maximum element contained within the vector.
-
-    The accum(x) function forms the cumulative sum of x, element by element.
-    Vector columns are supported simply by performing the summation process
-    through all the values.  Null values are treated as 0.  The seqdiff(x)
-    function forms the sequential difference of x, element by element.
-    The first value of seqdiff is the first value of x.  A single null
-    value in x causes a pair of nulls in the output.  The seqdiff and
-    accum functions are functional inverses, i.e., seqdiff(accum(x)) == x
-    as long as no null values are present.
-
-In the if-then-else expression, "b?x:y", b is an explicit boolean
-value or expression.  There is no automatic type conversion from
-numeric to boolean values, so one needs to use "iVal!=0" instead of
-merely "iVal" as the boolean argument. x and y can be any scalar data
-type (including string).
-
-    The angsep function computes the angular separation in degrees
-    between 2 celestial positions, where the first 2 parameters
-    give the RA-like and Dec-like coordinates (in decimal degrees)
-    of the first position, and the 3rd and 4th parameters give the
-    coordinates of the second position.
-
-The substring function strmid(S,P,N) extracts a substring from S,
-starting at string position P, with a substring length N.  The first
-character position in S is labeled as 1. If P is 0, or refers to a
-position beyond the end of S, then the extracted substring will be
-NULL.   S, P, and N may be functions of other columns.
-
-The string search function strstr(S,R) searches for the first occurrence
-of the substring R in S.  The result is an integer, indicating the
-character position of the first match (where 1 is the first character
-position of S).  If no match is found, then strstr() returns a NULL
-value.
-
-    The  following  type  casting  operators  are  available,  where the
-    enclosing parentheses are required and taken  from  the  C  language
-    usage. Also, the integer to real casts values to double precision:
-
-\begin{verbatim}
-                "real to integer"    (int) x     (INT) x
-                "integer to real"    (float) i   (FLOAT) i
-\end{verbatim}
-
-    In addition, several constants are built in  for  use  in  numerical
-    expressions:
-
-
-\begin{verbatim}
-        #pi              3.1415...      #e             2.7182...
-        #deg             #pi/180        #row           current row number
-        #null         undefined value   #snull         undefined string
-\end{verbatim}
-
-    A  string constant must  be enclosed  in quotes  as in  'Crab'.  The
-    "null" constants  are useful for conditionally  setting table values
-    to a NULL, or undefined, value (eg., "col1==-99 ? \#NULL : col1").
-
-    There is also a function for testing if  two  values  are  close  to
-    each  other,  i.e.,  if  they are "near" each other to within a user
-    specified tolerance. The  arguments,  value\_1  and  value\_2  can  be
-    integer  or  real  and  represent  the two values who's proximity is
-    being tested to be within the specified tolerance, also  an  integer
-    or real:
-
-\begin{verbatim}
-                    near(value_1, value_2, tolerance)
-\end{verbatim}
-    When  a  NULL, or undefined, value is encountered in the FITS table,
-    the expression will evaluate to NULL unless the undefined  value  is
-    not   actually   required  for  evaluation,  e.g. "TRUE  .or.  NULL"
-    evaluates to TRUE. The  following  two  functions  allow  some  NULL
-    detection  and  handling:
-
-\begin{verbatim}
-         "a null value?"              ISNULL(x)
-         "define a value for null"    DEFNULL(x,y)
-\end{verbatim}
-    The former
-    returns a boolean value of TRUE if the  argument  x  is  NULL.   The
-    later  "defines"  a  value  to  be  substituted  for NULL values; it
-    returns the value of x if x is not NULL, otherwise  it  returns  the
-    value of y.
-
-
-\subsection{Bit Masks}
-
-    Bit  masks can be used to select out rows from bit columns (TFORMn =
-    \#X) in FITS files. To represent the mask,  binary,  octal,  and  hex
-    formats are allowed:
-
-
-\begin{verbatim}
-                 binary:   b0110xx1010000101xxxx0001
-                 octal:    o720x1 -> (b111010000xxx001)
-                 hex:      h0FxD  -> (b00001111xxxx1101)
-\end{verbatim}
-
-    In  all  the  representations, an x or X is allowed in the mask as a
-    wild card. Note that the x represents a  different  number  of  wild
-    card  bits  in  each  representation.  All  representations are case
-    insensitive.
-
-    To construct the boolean expression using the mask  as  the  boolean
-    equal  operator  described above on a bit table column. For example,
-    if you had a 7 bit column named flags in a  FITS  table  and  wanted
-    all  rows  having  the bit pattern 0010011, the selection expression
-    would be:
-
-
-\begin{verbatim}
-                            flags == b0010011
-    or
-                            flags .eq. b10011
-\end{verbatim}
-
-    It is also possible to test if a range of bits is  less  than,  less
-    than  equal,  greater  than  and  greater than equal to a particular
-    boolean value:
-
-
-\begin{verbatim}
-                            flags <= bxxx010xx
-                            flags .gt. bxxx100xx
-                            flags .le. b1xxxxxxx
-\end{verbatim}
-
-    Notice the use of the x bit value to limit the range of  bits  being
-    compared.
-
-    It  is  not necessary to specify the leading (most significant) zero
-    (0) bits in the mask, as shown in the second expression above.
-
-    Bit wise AND, OR and NOT operations are  also  possible  on  two  or
-    more  bit  fields  using  the  '\&'(AND),  '$|$'(OR),  and the '!'(NOT)
-    operators. All of these operators result in a bit  field  which  can
-    then be used with the equal operator. For example:
-
-
-\begin{verbatim}
-                          (!flags) == b1101100
-                          (flags & b1000001) == bx000001
-\end{verbatim}
-
-    Bit  fields can be appended as well using the '+' operator.  Strings
-    can be concatenated this way, too.
-
-
-\subsection{Vector Columns}
-
-    Vector columns can also be used  in  building  the  expression.   No
-    special  syntax  is required if one wants to operate on all elements
-    of the vector.  Simply use the column name as for a  scalar  column.
-    Vector  columns  can  be  freely  intermixed  with scalar columns or
-    constants in virtually all expressions.  The result will be  of  the
-    same dimension as the vector.  Two vectors in an expression, though,
-    need to  have  the  same  number  of  elements  and  have  the  same
-    dimensions.   The  only  places  a vector column cannot be used (for
-    now, anyway) are the SAO  region  functions  and  the  NEAR  boolean
-    function.
-
-    Arithmetic and logical operations are all performed on an element by
-    element basis.  Comparing two vector columns,  eg  "COL1  ==  COL2",
-    thus  results  in  another vector of boolean values indicating which
-    elements of the two vectors are equal.
-
-    Eight functions are available that operate on a vector and return a
-    scalar result:
-
-\begin{verbatim}
-    "minimum"      MIN(V)          "maximum"               MAX(V)
-    "average"      AVERAGE(V)      "median"                MEDIAN(V)
-    "summation"    SUM(V)          "standard deviation"    STDDEV(V)
-    "# of values"  NELEM(V)        "# of non-null values"  NVALID(V)
-\end{verbatim}
-    where V represents the name of a vector column or a manually
-    constructed vector using curly brackets as described below.  The
-    first 6 of these functions ignore any null values in the vector when
-    computing the result.  The STDDEV() function computes the sample
-    standard deviation, i.e. it is proportional to 1/SQRT(N-1) instead
-    of 1/SQRT(N), where N is NVALID(V).
-
-    The SUM function literally sums all  the elements in x,  returning a
-    scalar value.   If x  is  a  boolean  vector, SUM returns the number
-    of TRUE elements. The NELEM function  returns the number of elements
-    in vector x whereas NVALID return the number of non-null elements in
-    the  vector.   (NELEM  also  operates  on  bit  and string  columns,
-    returning their column widths.)  As an example, to  test whether all
-    elements of two vectors satisfy a  given logical comparison, one can
-    use the expression
-
-\begin{verbatim}
-              SUM( COL1 > COL2 ) == NELEM( COL1 )
-\end{verbatim}
-
-    which will return TRUE if all elements  of  COL1  are  greater  than
-    their corresponding elements in COL2.
-
-    To  specify  a  single  element  of  a  vector, give the column name
-    followed by  a  comma-separated  list  of  coordinates  enclosed  in
-    square  brackets.  For example, if a vector column named PHAS exists
-    in the table as a one dimensional, 256  component  list  of  numbers
-    from  which  you  wanted to select the 57th component for use in the
-    expression, then PHAS[57] would do the  trick.   Higher  dimensional
-    arrays  of  data  may appear in a column.  But in order to interpret
-    them, the TDIMn keyword must appear in the header.  Assuming that  a
-    (4,4,4,4)  array  is packed into each row of a column named ARRAY4D,
-    the  (1,2,3,4)  component  element  of  each  row  is  accessed   by
-    ARRAY4D[1,2,3,4].    Arrays   up   to   dimension  5  are  currently
-    supported.  Each vector index can itself be an expression,  although
-    it  must  evaluate  to  an  integer  value  within the bounds of the
-    vector.  Vector columns which contain spaces or arithmetic operators
-    must   have   their   names  enclosed  in  "\$"  characters  as  with
-    \$ARRAY-4D\$[1,2,3,4].
-
-    A  more  C-like  syntax  for  specifying  vector  indices  is   also
-    available.   The element used in the preceding example alternatively
-    could be specified with the syntax  ARRAY4D[4][3][2][1].   Note  the
-    reverse  order  of  indices  (as in C), as well as the fact that the
-    values are still ones-based (as  in  Fortran  --  adopted  to  avoid
-    ambiguity  for  1D vectors).  With this syntax, one does not need to
-    specify all of the indices.  To  extract  a  3D  slice  of  this  4D
-    array, use ARRAY4D[4].
-
-    Variable-length vector columns are not supported.
-
-    Vectors can  be manually constructed  within the expression  using a
-    comma-separated list of  elements surrounded by curly braces ('\{\}').
-    For example, '\{1,3,6,1\}' is a 4-element vector containing the values
-    1, 3, 6, and 1.  The  vector can contain  only boolean, integer, and
-    real values (or expressions).  The elements will  be promoted to the
-    highest  datatype   present.  Any   elements   which  are themselves
-    vectors, will be expanded out with  each of its elements becoming an
-    element in the constructed vector.
-
-
-\subsection{Good Time Interval Filtering}
-
-    A common filtering method involves selecting rows which have a time
-    value which lies within what is called a Good Time Interval or GTI.
-    The time intervals are defined in a separate FITS table extension
-    which contains 2 columns giving the start and stop time of each
-    good interval.  The filtering operation accepts only those rows of
-    the input table which have an associated time which falls within
-    one of the time intervals defined in the GTI extension. A high
-    level function, gtifilter(a,b,c,d), is available which evaluates
-    each row of the input table  and returns TRUE  or FALSE depending
-    whether the row is inside or outside the  good time interval.  The
-    syntax is
-
-\begin{verbatim}
-      gtifilter( [ "gtifile" [, expr [, "STARTCOL", "STOPCOL" ] ] ] )
-\end{verbatim}
-    where  each "[]" demarks optional parameters.  Note that  the quotes
-    around the gtifile and START/STOP column are required.  Either single
-    or double quotes may be used.  In cases where this expression is
-    entered on the Unix command line, enclose the entire expression in
-    double quotes, and then use single quotes within the expression to
-    enclose the 'gtifile' and other terms.  It is also usually possible
-    to do the reverse, and enclose the whole expression in single quotes
-    and then use double quotes within the expression.  The gtifile,
-    if specified,  can be blank  ("") which will  mean to use  the first
-    extension  with   the name "*GTI*"  in   the current  file,  a plain
-    extension  specifier (eg, "+2",  "[2]", or "[STDGTI]") which will be
-    used  to  select  an extension  in  the current  file, or  a regular
-    filename with or without an extension  specifier which in the latter
-    case  will mean to  use the first  extension  with an extension name
-    "*GTI*".  Expr can be   any arithmetic expression, including  simply
-    the time  column  name.  A  vector  time expression  will  produce a
-    vector boolean  result.  STARTCOL and  STOPCOL are the  names of the
-    START/STOP   columns in the    GTI extension.  If   one  of them  is
-    specified, they both  must be.
-
-    In  its  simplest form, no parameters need to be provided -- default
-    values will be used.  The expression "gtifilter()" is equivalent to
-
-\begin{verbatim}
-       gtifilter( "", TIME, "*START*", "*STOP*" )
-\end{verbatim}
-    This will search the current file for a GTI  extension,  filter  the
-    TIME  column in the current table, using START/STOP times taken from
-    columns in the GTI  extension  with  names  containing  the  strings
-    "START"  and "STOP".  The wildcards ('*') allow slight variations in
-    naming conventions  such  as  "TSTART"  or  "STARTTIME".   The  same
-    default  values  apply for unspecified parameters when the first one
-    or  two  parameters  are  specified.   The  function   automatically
-    searches   for   TIMEZERO/I/F   keywords  in  the  current  and  GTI
-    extensions, applying a relative time offset, if necessary.
-
-
-\subsection{Spatial Region Filtering}
-
-    Another common  filtering method selects rows based on whether the
-    spatial position associated with each row is located within a given
-    2-dimensional region.  The syntax for this high-level filter is
-
-\begin{verbatim}
-       regfilter( "regfilename" [ , Xexpr, Yexpr [ , "wcs cols" ] ] )
-\end{verbatim}
-    where each "[]" demarks optional parameters. The region file name
-    is required and must be  enclosed in quotes.  The remaining
-    parameters are optional.  There are 2 supported formats for the
-    region file: ASCII file or FITS binary table.  The region file
-    contains a list of one or more geometric shapes (circle,
-    ellipse, box, etc.) which defines a region on the celestial sphere
-    or an area within a particular 2D image.  The region file is
-    typically generated using an image display program such as fv/POW
-    (distribute by the HEASARC), or ds9 (distributed by the Smithsonian
-    Astrophysical Observatory).  Users should refer to the documentation
-    provided with these programs for more details on the syntax used in
-    the region files.  The FITS region file format is defined in a document
-    available from the FITS Support Office at
-    http://fits.gsfc.nasa.gov/ registry/ region.html
-
-    In its simplest form, (e.g., regfilter("region.reg") ) the
-    coordinates in the default 'X' and 'Y' columns will be used to
-    determine if each row is inside or outside the area specified in
-    the region file.  Alternate position column names, or expressions,
-    may be entered if needed, as in
-
-\begin{verbatim}
-        regfilter("region.reg", XPOS, YPOS)
-\end{verbatim}
-    Region filtering can be applied most unambiguously if the positions
-    in the region file and in the table to be filtered are both give in
-    terms of absolute celestial coordinate units.  In this case the
-    locations and sizes of the geometric shapes in the region file are
-    specified in angular units on the sky (e.g., positions given in
-    R.A. and Dec.  and sizes in arcseconds or arcminutes).  Similarly,
-    each row of the filtered table will have a celestial coordinate
-    associated with it.  This association is usually implemented using
-    a set of so-called 'World Coordinate System' (or WCS) FITS keywords
-    that define the coordinate transformation that must be applied to
-    the values in the 'X' and 'Y' columns to calculate the coordinate.
-
-    Alternatively, one can perform spatial filtering using unitless
-    'pixel' coordinates for the regions and row positions.  In this
-    case the user must be careful to ensure that the positions in the 2
-    files are self-consistent.  A typical problem is that the region
-    file may be generated using a binned image, but the unbinned
-    coordinates are given in the event table.  The ROSAT events files,
-    for example, have X and Y pixel coordinates that range from 1 -
-    15360.  These coordinates are typically binned by a factor of 32 to
-    produce a 480x480 pixel image.  If one then uses a region file
-    generated from this image (in image pixel units) to filter the
-    ROSAT events file, then the X and Y column values must be converted
-    to corresponding pixel units as in:
-
-\begin{verbatim}
-        regfilter("rosat.reg", X/32.+.5, Y/32.+.5)
-\end{verbatim}
-    Note that this binning conversion is not necessary if the region
-    file is specified using celestial coordinate units instead of pixel
-    units because CFITSIO is then able to directly compare the
-    celestial coordinate of each row in the table with the celestial
-    coordinates in the region file without having to know anything
-    about how the image may have been binned.
-
-    The last "wcs cols" parameter should rarely be needed. If supplied,
-    this  string contains the names of the 2 columns (space or comma
-    separated) which have the associated WCS keywords. If not supplied,
-    the filter  will scan the X  and Y expressions for column names.
-    If only one is found in each  expression, those columns will be
-    used, otherwise an error will be returned.
-
-    These region shapes are supported (names are case insensitive):
-
-\begin{verbatim}
-       Point         ( X1, Y1 )               <- One pixel square region
-       Line          ( X1, Y1, X2, Y2 )       <- One pixel wide region
-       Polygon       ( X1, Y1, X2, Y2, ... )  <- Rest are interiors with
-       Rectangle     ( X1, Y1, X2, Y2, A )       | boundaries considered
-       Box           ( Xc, Yc, Wdth, Hght, A )   V within the region
-       Diamond       ( Xc, Yc, Wdth, Hght, A )
-       Circle        ( Xc, Yc, R )
-       Annulus       ( Xc, Yc, Rin, Rout )
-       Ellipse       ( Xc, Yc, Rx, Ry, A )
-       Elliptannulus ( Xc, Yc, Rinx, Riny, Routx, Routy, Ain, Aout )
-       Sector        ( Xc, Yc, Amin, Amax )
-\end{verbatim}
-    where (Xc,Yc) is  the coordinate of  the shape's center; (X\#,Y\#) are
-    the coordinates  of the shape's edges;  Rxxx are the shapes' various
-    Radii or semi-major/minor  axes; and Axxx  are the angles of rotation
-    (or bounding angles for Sector) in degrees.  For rotated shapes, the
-    rotation angle  can  be left  off, indicating  no rotation.   Common
-    alternate  names for the regions  can also be  used: rotbox = box;
-    rotrectangle = rectangle;  (rot)rhombus = (rot)diamond;  and pie
-    = sector.  When a  shape's name is  preceded by a minus sign, '-',
-    the defined region  is instead the area  *outside* its boundary (ie,
-    the region is inverted).  All the shapes within a single region
-    file are OR'd together to create the region, and the order is
-    significant. The overall way of looking at region files is that if
-    the first region is an excluded region then a dummy included region
-    of the whole detector is inserted in the front. Then each region
-    specification as it is processed overrides any selections inside of
-    that region specified by previous regions. Another way of thinking
-    about this is that if a previous excluded region is completely
-    inside of a subsequent included region the excluded region is
-    ignored.
-
-    The positional coordinates may be given either in pixel units,
-    decimal degrees or hh:mm:ss.s, dd:mm:ss.s units.  The shape sizes
-    may be given in pixels, degrees, arcminutes, or arcseconds.  Look
-    at examples of region file produced by fv/POW or ds9 for further
-    details of the region file format.
-
-    There are three functions that are primarily for use with SAO region
-    files and the  FSAOI  task, but they  can  be  used  directly.  They
-    return  a  boolean true   or  false  depending   on  whether a   two
-    dimensional point is in the region or not:
-
-\begin{verbatim}
-    "point in a circular region"
-          circle(xcntr,ycntr,radius,Xcolumn,Ycolumn)
-
-    "point in an elliptical region"
-         ellipse(xcntr,ycntr,xhlf_wdth,yhlf_wdth,rotation,Xcolumn,Ycolumn)
-
-    "point in a rectangular region"
-             box(xcntr,ycntr,xfll_wdth,yfll_wdth,rotation,Xcolumn,Ycolumn)
-
-    where
-       (xcntr,ycntr) are the (x,y) position of the center of the region
-       (xhlf_wdth,yhlf_wdth) are the (x,y) half widths of the region
-       (xfll_wdth,yfll_wdth) are the (x,y) full widths of the region
-       (radius) is half the diameter of the circle
-       (rotation) is the angle(degrees) that the region is rotated with
-             respect to (xcntr,ycntr)
-       (Xcoord,Ycoord) are the (x,y) coordinates to test, usually column
-             names
-       NOTE: each parameter can itself be an expression, not merely a
-             column name or constant.

-\section{ Binning or Histogramming Specification}
-
-The optional binning specifier is enclosed in square brackets and can
-be distinguished from a general row filter specification by the fact
-that it begins with the keyword 'bin'  not immediately followed by an
-equals sign.  When binning is specified, a temporary N-dimensional FITS
-primary array is created by computing the histogram of the values in
-the specified columns of a FITS table extension.  After the histogram
-is computed the input FITS file containing the table is then closed and
-the temporary FITS primary array is opened and passed to the
-application program.  Thus, the application program never sees the
-original FITS table and only sees the image in the new temporary file
-(which has no additional extensions).  Obviously, the application
-program must be expecting to open a FITS image and not a FITS table in
-this case.
-
-The data type of the FITS histogram image may be specified by appending
-'b' (for 8-bit byte), 'i' (for 16-bit integers), 'j' (for 32-bit
-integer), 'r' (for 32-bit floating points), or 'd' (for 64-bit double
-precision floating point)  to the 'bin' keyword (e.g. '[binr X]'
-creates a real floating point image).  If the datatype is not
-explicitly specified then a 32-bit integer image will be created by
-default, unless the weighting option is also specified in which case
-the image will have a 32-bit floating point data type by default.
-
-The histogram image may have from 1 to 4 dimensions (axes), depending
-on the number of columns that are specified.  The general form of the
-binning specification is:
-
-\begin{verbatim}
- [bin{bijrd}  Xcol=min:max:binsize, Ycol= ..., Zcol=..., Tcol=...; weight]
-\end{verbatim}
-in which up to 4 columns, each corresponding to an axis of the image,
-are listed. The column names are case insensitive, and the column
-number may be given instead of the name, preceded by a pound sign
-(e.g., [bin \#4=1:512]).  If the column name is not specified, then
-CFITSIO will first try to use the 'preferred column' as specified by
-the CPREF keyword if it exists (e.g., 'CPREF = 'DETX,DETY'), otherwise
-column names 'X', 'Y', 'Z', and 'T' will be assumed for each of the 4
-axes, respectively.  In cases where the column name could be confused
-with an arithmetic expression, enclose the column name in parentheses to
-force the name to be interpreted literally.
-
-Each column name may be followed by an equals sign and then the lower
-and upper range of the histogram, and the size of the histogram bins,
-separated by colons.  Spaces are allowed before and after the equals
-sign but not within the 'min:max:binsize' string.  The min, max and
-binsize values may be integer or floating point numbers, or they may be
-the names of keywords in the header of the table.  If the latter, then
-the value of that keyword is substituted into the expression.
-
-Default values for the min, max and binsize quantities will be
-used if not explicitly given in the binning expression as shown
-in these examples:
-
-\begin{verbatim}
-    [bin x = :512:2]  - use default minimum value
-    [bin x = 1::2]    - use default maximum value
-    [bin x = 1:512]   - use default bin size
-    [bin x = 1:]      - use default maximum value and bin size
-    [bin x = :512]    - use default minimum value and bin size
-    [bin x = 2]       - use default minimum and maximum values
-    [bin x]           - use default minimum, maximum and bin size
-    [bin 4]           - default 2-D image, bin size = 4 in both axes
-    [bin]             - default 2-D image
-\end{verbatim}
-CFITSIO  will use the value of the TLMINn, TLMAXn, and TDBINn keywords,
-if they exist, for the default min, max, and binsize, respectively.  If
-they do not exist then CFITSIO will use the actual minimum and maximum
-values in the column for the histogram min and max values.  The default
-binsize will be set to 1, or (max - min) / 10., whichever is smaller,
-so that the histogram will have at least 10 bins along each axis.
-
-A shortcut notation is allowed if all the columns/axes have the same
-binning specification.  In this case all the column names may be listed
-within parentheses, followed by the (single) binning specification, as
-in:
-
-\begin{verbatim}
-    [bin (X,Y)=1:512:2]
-    [bin (X,Y) = 5]
-\end{verbatim}
-
-The optional weighting factor is the last item in the binning specifier
-and, if present, is separated from the list of columns by a
-semi-colon.  As the histogram is accumulated, this weight is used to
-incremented the value of the appropriated bin in the histogram.  If the
-weighting factor is not specified, then the default weight = 1 is
-assumed.  The weighting factor may be a constant integer or floating
-point number, or the name of a keyword containing the weighting value.
-Or the weighting factor may be the name of a table column in which case
-the value in that column, on a row by row basis, will be used.
-
-In some cases, the column or keyword may give the reciprocal of the
-actual weight value that is needed.  In this case, precede the weight
-keyword or column name by a slash '/' to tell CFITSIO to use the
-reciprocal of the value when constructing the histogram.
-
-For  complex or commonly  used  histograms, one  can also  place its
-description  into  a  text  file and  import   it  into  the binning
-specification  using the  syntax '[bin  @filename.txt]'.  The file's
-contents  can extend over   multiple lines, although  it must still
-conform to the  no-spaces rule  for the min:max:binsize syntax and each
-axis specification must still be comma-separated.  Any lines in the
-external text file that begin with 2 slash characters ('//') will be
-ignored and may be used to add comments into the file.
-
- Examples:
-
-
-\begin{verbatim}
-    [bini detx, dety]                - 2-D, 16-bit integer histogram
-                                       of DETX and DETY columns, using
-                                       default values for the histogram
-                                       range and binsize
-
-    [bin (detx, dety)=16; /exposure] - 2-D, 32-bit real histogram of DETX
-                                       and DETY columns with a bin size = 16
-                                       in both axes. The histogram values
-                                       are divided by the EXPOSURE keyword
-                                       value.
-
-    [bin time=TSTART:TSTOP:0.1]      - 1-D lightcurve, range determined by

-\chapter{Template Files }
-
-When a new FITS file is created with a call to fits\_create\_file, the
-name of a template file may be supplied in parentheses immediately
-following the name of the new file to be created.  This template is
-used to define the structure of one or more HDUs in the new file.  The
-template file may be another FITS file, in which case the newly created
-file will have exactly the same keywords in each HDU as in the template
-FITS file, but all the data units will be filled with zeros.  The
-template file may also be an ASCII text file, where each line (in
-general) describes one FITS keyword record.  The format of the ASCII
-template file is described in the following sections.
-
-
-\section{Detailed Template Line Format}
-
-The format of each ASCII template line closely follows the format of a
-FITS keyword record:
-
-\begin{verbatim}
-  KEYWORD = KEYVALUE / COMMENT
-\end{verbatim}
-except that free format may be used (e.g., the equals sign may appear
-at any position in the line) and TAB characters are allowed and are
-treated the same as space characters.  The KEYVALUE and COMMENT fields
-are optional.  The equals sign character is also optional, but it is
-recommended that it be included for clarity.  Any template line that
-begins with the pound '\#' character is ignored by the template parser
-and may be use to insert comments into the template file itself.
-
-The KEYWORD name field is limited to 8 characters in length and only
-the letters A-Z, digits 0-9, and the hyphen and underscore characters
-may be used, without any embedded spaces. Lowercase letters in the
-template keyword name will be converted to uppercase.  Leading spaces
-in the template line preceding the keyword name are generally ignored,
-except if the first 8 characters of a template line are all blank, then
-the entire line is treated as a FITS comment keyword (with a blank
-keyword name) and is copied verbatim into the FITS header.
-
-The KEYVALUE field may have any allowed  FITS  data type: character
-string, logical, integer, real, complex integer, or complex real.  The
-character string values need not be enclosed in single quote characters
-unless they are necessary to distinguish the string from a different
-data type (e.g.  2.0 is a real but '2.0' is a string).  The keyword has
-an undefined (null) value if the template record only contains blanks
-following the "=" or between the "=" and the "/" comment field
-delimiter.
-
-String keyword values longer than 68 characters (the maximum length
-that will fit in a single FITS keyword record) are permitted using the
-CFITSIO long string convention. They can either be specified as a
-single long line in the template, or by using multiple lines where the
-continuing lines contain the 'CONTINUE' keyword, as in this example:
-
-\begin{verbatim}
-  LONGKEY = 'This is a long string value that is contin&'
-  CONTINUE  'ued over 2 records' / comment field goes here
-\end{verbatim}
-The format of template lines with CONTINUE keyword is very strict:  3
-spaces must follow CONTINUE and the rest of the line is copied verbatim
-to the FITS file.
-
-The start of the optional COMMENT field must be preceded by "/", which
-is used to separate it from the keyword value field. Exceptions are if
-the KEYWORD name field contains COMMENT, HISTORY, CONTINUE, or if the
-first 8 characters of the template line are blanks.
-
-More than one Header-Data Unit (HDU) may be defined in the template
-file.  The start of an HDU definition is denoted with a SIMPLE or
-XTENSION template line:
-
-1) SIMPLE begins a Primary HDU definition. SIMPLE may only appear as
-the  first keyword in the template file. If the template file begins
-with XTENSION instead of SIMPLE, then a default empty Primary HDU is
-created, and the template is then assumed to define the keywords
-starting with the first extension following the Primary HDU.
-
-2) XTENSION marks the beginning of a new extension HDU definition.  The
-previous HDU will be closed at this point and processing of the next
-extension begins.
-
-
-\section{Auto-indexing of Keywords}
-
-If a template keyword name ends with a "\#" character, it is said to be
-'auto-indexed'.   Each "\#" character will be replaced by the current
-integer index value, which gets reset = 1 at the start of each new HDU
-in the file (or 7 in the special case of a GROUP definition).  The
-FIRST indexed keyword in each template HDU definition is used as the
-'incrementor';  each subsequent occurrence of this SAME keyword will
-cause the index value to be incremented.  This behavior can be rather
-subtle, as illustrated in the following examples in which the TTYPE
-keyword is the incrementor in both cases:
-
-\begin{verbatim}
-  TTYPE# = TIME
-  TFORM# = 1D
-  TTYPE# = RATE
-  TFORM# = 1E
-\end{verbatim}
-will create TTYPE1, TFORM1, TTYPE2, and TFORM2 keywords.  But if the
-template looks like,
-
-\begin{verbatim}
-  TTYPE# = TIME
-  TTYPE# = RATE
-  TFORM# = 1D
-  TFORM# = 1E
-\end{verbatim}
-this results in a FITS files with  TTYPE1, TTYPE2, TFORM2, and TFORM2,
-which is probably not what was intended!
-
-
-\section{Template Parser Directives}
-
-In addition to the template lines which define individual keywords, the
-template parser recognizes 3 special directives which are each preceded
-by the backslash character:  \verb+ \include, \group+, and \verb+ \end+.
-
-The 'include' directive must be followed by a filename. It forces the
-parser to temporarily stop reading the current template file and begin
-reading the include file. Once the parser reaches the end of the
-include file it continues parsing the current template file.  Include
-files can be nested, and HDU definitions can span multiple template
-files.
-
-The start of a GROUP definition is denoted with the 'group' directive,
-and the end of a GROUP definition is denoted with the 'end' directive.
-Each GROUP contains 0 or more member blocks (HDUs or GROUPs). Member
-blocks of type GROUP can contain their own member blocks. The GROUP
-definition itself occupies one FITS file HDU of special type (GROUP
-HDU), so if a template specifies 1 group with 1 member HDU like:
-
-\begin{verbatim}
-\group
-grpdescr = 'demo'
-xtension bintable
-# this bintable has 0 cols, 0 rows
-\end
-\end{verbatim}
-then the parser creates a FITS file with 3 HDUs :
-
-\begin{verbatim}
-1) dummy PHDU
-2) GROUP HDU (has 1 member, which is bintable in HDU number 3)
-3) bintable (member of GROUP in HDU number 2)
-\end{verbatim}
-Technically speaking, the GROUP HDU is a BINTABLE with 6 columns. Applications
-can define additional columns in a GROUP HDU using TFORMn and TTYPEn
-(where n is 7, 8, ....) keywords or their auto-indexing equivalents.
-
-For a more complicated example of a template file using the group directives,
-look at the sample.tpl file that is included in the CFITSIO distribution.
-
-
-\section{Formal Template Syntax}
-
-The template syntax can formally be defined as follows:
-
-\begin{verbatim}
-    TEMPLATE = BLOCK [ BLOCK ... ]
-
-       BLOCK = { HDU | GROUP }
-
-       GROUP = \GROUP [ BLOCK ... ] \END
-
-         HDU = XTENSION [ LINE ... ] { XTENSION | \GROUP | \END | EOF }
-
-        LINE = [ KEYWORD [ = ] ] [ VALUE ] [ / COMMENT ]
-
-    X ...     - X can be present 1 or more times
-    { X | Y } - X or Y
-    [ X ]     - X is optional
-\end{verbatim}
-
-At the topmost level, the template defines 1 or more template blocks. Blocks
-can be either HDU (Header Data Unit) or a GROUP. For each block the parser
-creates 1 (or more for GROUPs) FITS file HDUs.
-
-
-
-\section{Errors}
-
-In general the fits\_execute\_template() function tries to be as atomic
-as possible, so either everything is done or nothing is done. If an
-error occurs during parsing of the template, fits\_execute\_template()
-will (try to) delete the top level BLOCK (with all its children if any)
-in which the error occurred, then it will stop reading the template file
-and it will return with an error.
-
-
-\section{Examples}
-
-1. This template file will create a 200 x 300 pixel image, with 4-byte
-integer pixel values, in the primary HDU:
-
-\begin{verbatim}
-  SIMPLE = T
-  BITPIX = 32
-  NAXIS = 2     / number of dimensions
-  NAXIS1 = 100  / length of first axis
-  NAXIS2 = 200  / length of second axis
-  OBJECT = NGC 253 / name of observed object
-\end{verbatim}
-The allowed values of BITPIX are 8, 16, 32, -32, or -64,
-representing, respectively, 8-bit integer, 16-bit integer, 32-bit
-integer, 32-bit floating point, or 64 bit floating point pixels.
-
-2.  To create a FITS  table, the template first needs to include
-XTENSION = TABLE or BINTABLE to define whether it is an ASCII or binary
-table, and NAXIS2 to define the number of rows in the table.  Two
-template lines are then needed to define the name (TTYPEn) and FITS data
-format (TFORMn) of the columns, as in this example:
-
-\begin{verbatim}
-  xtension = bintable
-  naxis2 = 40
-  ttype# = Name
-  tform# = 10a
-  ttype# = Npoints
-  tform# = j
-  ttype# = Rate
-  tunit# = counts/s
-  tform# = e
-\end{verbatim}
-The above example defines a null primary array followed by a 40-row
-binary table extension with 3 columns called 'Name', 'Npoints', and
-'Rate', with data formats of '10A' (ASCII character string), '1J'
-(integer) and '1E' (floating point), respectively.  Note that the other
-required FITS keywords (BITPIX, NAXIS, NAXIS1, PCOUNT, GCOUNT, TFIELDS,
-and END) do not need to be explicitly defined in the template because
-their values can be inferred from the other keywords in the template.
-This example also illustrates that the templates are generally
-case-insensitive (the keyword names and TFORMn values are converted to
-upper-case in the FITS file) and that string keyword values generally
-do not need to be enclosed in quotes.

-VERSION	History
-
-1.6.0 (June 2012)
-    - Fixed behavior of the "rename" function on Windows platforms so that
-      it will clobber/delete an existing file before renaming a file to 
-      that name (the rename command behaves differently on POSIX and non-POSIX
-      environments).
-
-1.6.0 (February 2011)
-    - Added full support for compressing and uncompressing FITS binary tables
-      using a newly proposed format convention.  This is intended only for
-      further feasibility studies, and is not recommended for use with publicly
-      distributed FITS files.
-    - Use the minimum of the MAD 2nd, 3rd, and 5th order values as a more
-      conservative extimate of the noise when quantizing floating point images.
-    - Enhanced the tile compression routines so that a tile that contains all
-      NaN pixel values will be compressed.
-    - When uncompressing an image that was originally in a FITS primary array,
-      funpack will also append any new keywords that were written into the 
-      primary array of the compressed FITS file after the file was compressed.
-    - Added support for the GZIP_2 algorithm, which shuffles the bytes in the
-      pixel values prior to compressing them with gzip.      
-1.5.1 (December 2010) Added prototype, mainly hidden, support for compressing 
-      binary tables.  
-1.5.0 (August 2010) Added the -i2f option to lossy compress integer images.
-1.4.0 (Jan 2010) Reduced the default value for the q floating point image 
-      quantization parameter from 16 to 4.  This results in about 50% better
-      compression (from about 4.6x to 6.4) with no lost of significant information 
-      (with the new subtractive dithering enhancement).  Replaced the code for
-      generating temporary filenames to make the code more portable (to Windows). 
-      Replaced calls to the unix 'access' and 'stat' functions with more portable
-      code.   When unpacking a file, write it first to a temporary file, then
-      rename it when finished, so that other tasks cannot try to read the file
-      before it is complete.
-1.3.0 (Oct 2009) added randomization to the dithering pattern so that
-      the same pattern is not used for every image; also added an option
-      for losslessly compressing floating point images with GZIP for test 
-      purposes (not recommended for general use).  Also added support for
-      reading the input FITS file from the stdin file streams.
-1.2.0 (Sept 2009) added subtractive dithering feature (in CFITSIO) when
-      quantizing floating point images; When packing an IRAF .imh + .pix image,
-      the file name is changed to FILE.fits.fz, and if the original file is
-      deleted, then both the .imh and .pix files are deleted.
-1.1.4 (May 2009) added -E option to funpack to unpack a list of HDUs
-1.1.3 (March 2009)  minor modifications to the content and format of the -T report
-1.1.2 (September 2008)

- Change record:
-
-D. Jennings, 18/06/98, version 1.0 of group module delivered to B. Pence for
-                       integration into CFITSIO 2.005
-
-D. Jennings, 17/11/98, fixed bug in ffgtcpr(). Now use fits_find_nextkey()
-                       correctly and insert auxiliary keyword records 
-		       directly before the TTYPE1 keyword in the copied
-		       group table.
-
-D. Jennings, 22/01/99, ffgmop() now looks for relative file paths when 
-                       the MEMBER_LOCATION information is given in a 
-		       grouping table.
-
-D. Jennings, 01/02/99, ffgtop() now looks for relatve file paths when 
-                       the GRPLCn keyword value is supplied in the member
-		       HDU header.
-
-D. Jennings, 01/02/99, ffgtam() now trys to construct relative file paths
-                       from the member's file to the group table's file
-		       (and visa versa) when both the member's file and
-		       group table file are of access type FILE://.
-
-D. Jennings, 05/05/99, removed the ffgtcn() function; made obsolete by

-D. Jennings, 05/05/99, updated entire module to handle partial URLs and
-                       absolute URLs more robustly. Host dependent directory
-		       paths are now converted to true URLs before being
-		       read from/written to grouping tables.
-
-D. Jennings, 05/05/99, added the following new functions (note, none of these
-                       are directly callable by the application)
-
-		       int fits_path2url()
-		       int fits_url2path()
-		       int fits_get_cwd()
-		       int fits_get_url()

-14-Oct-98: initial release
-16-Oct-98: code cleanup, #include <string.h> included, now gcc -Wall prints no
-		warnings during compilation. Bugfix: now one can specify additional
-		columns in group HDU. Autoindexing also works in this situation
-		(colunms are number from 7 however).
-17-Oct-98: bugfix: complex keywords were incorrectly written (was TCOMPLEX should
-		be TDBLCOMPLEX).
-20-Oct-98: bugfix: parser was writing EXTNAME twice, when first HDU in template is
-		defined with XTENSION IMAGE then parser creates now dummy PHDU,
-		SIMPLE T is now allowed only at most once and in first HDU only.
-		WARNING: one should not define EXTNAME keyword for GROUP HDUs, as
-		they have them already defined by parser (EXTNAME = GROUPING).
-		Parser accepts EXTNAME oin GROUP HDU definition, but in this
-		case multiple EXTNAME keywords will present in HDU header.
-23-Oct-98: bugfix: unnecessary space was written to FITS file for blank
-		keywords.
-24-Oct-98: syntax change: empty lines and lines with only whitespaces are 
-		written to FITS files as blank keywords (if inside group/hdu
-		definition). Previously lines had to have at least 8 spaces.
-		Please note, that due to pecularities of CFITSIO if the
-		last keyword(s) defined for given HDU are blank keywords
-		consisting of only 80 spaces, then (some of) those keywords
-		may be silently deleted by CFITSIO.
-13-Nov-98: bugfix: parser was writing GRPNAME twice. Parser still creates
-                GRPNAME keywords for GROUP HDU's which do not specify them.
-                However, values (of form DEFAULT_GROUP_XXX) are assigned
-                not necessarily in order HDUs appear in template file, but
-                rather in order parser completes their creation in FITS
-                file. Also, when including files, if fopen fails, parser
-                tries to open file with a name = directory_of_top_level
-                file + name of file to be included, as long as name
-                of file to be included does not specify absolute pathname.
-16-Nov-98: bugfix to bugfix from 13-Nov-98
-19-Nov-98: EXTVER keyword is now automatically assigned value by parser.
-17-Dev-98: 2 new things added: 1st: CFITSIO_INCLUDE_FILES environment
-		variable can contain a colon separated list of directories
-		to look for when looking for template include files (and master
-		template also). 2nd: it is now possible to append template
-		to nonempty FITS. file. fitsfile *ff no longer needs to point
-		to an empty FITS file with 0 HDUs in it. All data written by
-		parser will simple be appended at the end of file.
-22-Jan-99: changes to parser: when in append mode parser initially scans all
-		existing HDUs to built a list of already used EXTNAME/EXTVERs
-22-Jan-99: Bruce O'Neel, bugfix : TLONG should always reference long type
-		variable on OSF/Alpha and on 64-bit archs in general
-20-Jun-2002 Wm Pence, added support for the HIERARCH keyword convention in
-                which keyword names can effectively be longer than 8 characters.
-                Example:
-                HIERARCH  LongKeywordName = 'value' / comment
-30-Jan-2003 Wm Pence, bugfix: ngp_read_xtension was testing for "ASCIITABLE" 
-                instead of "TABLE" as the XTENSION value of an ASCII table,
-                and it did not allow for optional trailing spaces in the
-                "IMAGE" or "TABLE" string. 
-16-Dec-2003 James Peachey: ngp_keyword_all_write was modified to apply
-                comments from the template file to the output file in
-                the case of reserved keywords (e.g. tform#, ttype# etcetera).

-   strm provides the memory allocation functions and window buffer on input,
-   and provides information on the unused input on return.  For Z_DATA_ERROR
-   returns, strm will also provide an error message.
-
-   in() and out() are the call-back input and output functions.  When
-   inflateBack() needs more input, it calls in().  When inflateBack() has
-   filled the window with output, or when it completes with data in the
-   window, it calls out() to write out the data.  The application must not
-   change the provided input until in() is called again or inflateBack()
-   returns.  The application must not change the window/output buffer until
-   inflateBack() returns.
-
-   in() and out() are called with a descriptor parameter provided in the
-   inflateBack() call.  This parameter can be a structure that provides the
-   information required to do the read or write, as well as accumulated
-   information on the input and output such as totals and check values.
-
-   in() should return zero on failure.  out() should return non-zero on
-   failure.  If either in() or out() fails, than inflateBack() returns a
-   Z_BUF_ERROR.  strm->next_in can be checked for Z_NULL to see whether it
-   was in() or out() that caused in the error.  Otherwise,  inflateBack()
-   returns Z_STREAM_END on success, Z_DATA_ERROR for an deflate format
-   error, or Z_MEM_ERROR if it could not allocate memory for the state.
-   inflateBack() can also return Z_STREAM_ERROR if the input parameters
-   are not correct, i.e. strm is Z_NULL or the state was not initialized.

-   Decode literal, length, and distance codes and write out the resulting
-   literal and match bytes until either not enough input or output is
-   available, an end-of-block is encountered, or a data error is encountered.
-   When large enough input and output buffers are supplied to inflate(), for
-   example, a 16K input buffer and a 64K output buffer, more than 95% of the
-   inflate execution time is spent in this routine.
-
-   Entry assumptions:
-
-        state->mode == LEN
-        strm->avail_in >= 6
-        strm->avail_out >= 258
-        start >= strm->avail_out
-        state->bits < 8
-
-   On return, state->mode is one of:
-
-        LEN -- ran out of enough output space or enough available input
-        TYPE -- reached end of block code, inflate() to interpret next block
-        BAD -- error in block data
-
-   Notes:
-
-    - The maximum input bits used by a length/distance pair is 15 bits for the
-      length code, 5 bits for the length extra, 15 bits for the distance code,
-      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
-      Therefore if strm->avail_in >= 6, then there is enough input to avoid
-      checking for available input while decoding.
-
-    - The maximum bytes that a single length/distance pair can output is 258
-      bytes, which is the maximum length that can be coded.  inflate_fast()
-      requires strm->avail_out >= 258 for each loop to avoid checking for
-      output space.

-/* inflate.c -- zlib decompression
- * Copyright (C) 1995-2010 Mark Adler
- * For conditions of distribution and use, see copyright notice in zlib.h
- */
-
-/*
- * Change history:
- *
- * 1.2.beta0    24 Nov 2002
- * - First version -- complete rewrite of inflate to simplify code, avoid
- *   creation of window when not needed, minimize use of window when it is
- *   needed, make inffast.c even faster, implement gzip decoding, and to
- *   improve code readability and style over the previous zlib inflate code
- *
- * 1.2.beta1    25 Nov 2002
- * - Use pointers for available input and output checking in inffast.c
- * - Remove input and output counters in inffast.c
- * - Change inffast.c entry and loop from avail_in >= 7 to >= 6
- * - Remove unnecessary second byte pull from length extra in inffast.c
- * - Unroll direct copy to three copies per loop in inffast.c
- *
- * 1.2.beta2    4 Dec 2002
- * - Change external routine names to reduce potential conflicts
- * - Correct filename to inffixed.h for fixed tables in inflate.c
- * - Make hbuf[] unsigned char to match parameter type in inflate.c
- * - Change strm->next_out[-state->offset] to *(strm->next_out - state->offset)
- *   to avoid negation problem on Alphas (64 bit) in inflate.c
- *
- * 1.2.beta3    22 Dec 2002
- * - Add comments on state->bits assertion in inffast.c
- * - Add comments on op field in inftrees.h
- * - Fix bug in reuse of allocated window after inflateReset()
- * - Remove bit fields--back to byte structure for speed
- * - Remove distance extra == 0 check in inflate_fast()--only helps for lengths
- * - Change post-increments to pre-increments in inflate_fast(), PPC biased?
- * - Add compile time option, POSTINC, to use post-increments instead (Intel?)
- * - Make MATCH copy in inflate() much faster for when inflate_fast() not used
- * - Use local copies of stream next and avail values, as well as local bit
- *   buffer and bit count in inflate()--for speed when inflate_fast() not used
- *
- * 1.2.beta4    1 Jan 2003
- * - Split ptr - 257 statements in inflate_table() to avoid compiler warnings
- * - Move a comment on output buffer sizes from inffast.c to inflate.c
- * - Add comments in inffast.c to introduce the inflate_fast() routine
- * - Rearrange window copies in inflate_fast() for speed and simplification
- * - Unroll last copy for window match in inflate_fast()
- * - Use local copies of window variables in inflate_fast() for speed
- * - Pull out common wnext == 0 case for speed in inflate_fast()
- * - Make op and len in inflate_fast() unsigned for consistency
- * - Add FAR to lcode and dcode declarations in inflate_fast()
- * - Simplified bad distance check in inflate_fast()
- * - Added inflateBackInit(), inflateBack(), and inflateBackEnd() in new
- *   source file infback.c to provide a call-back interface to inflate for
- *   programs like gzip and unzip -- uses window as output buffer to avoid
- *   window copying
- *
- * 1.2.beta5    1 Jan 2003
- * - Improved inflateBack() interface to allow the caller to provide initial
- *   input in strm.
- * - Fixed stored blocks bug in inflateBack()
- *
- * 1.2.beta6    4 Jan 2003
- * - Added comments in inffast.c on effectiveness of POSTINC
- * - Typecasting all around to reduce compiler warnings
- * - Changed loops from while (1) or do {} while (1) to for (;;), again to
- *   make compilers happy
- * - Changed type of window in inflateBackInit() to unsigned char *
- *
- * 1.2.beta7    27 Jan 2003
- * - Changed many types to unsigned or unsigned short to avoid warnings
- * - Added inflateCopy() function
- *
- * 1.2.0        9 Mar 2003
- * - Changed inflateBack() interface to provide separate opaque descriptors
- *   for the in() and out() functions
- * - Changed inflateBack() argument and in_func typedef to swap the length
- *   and buffer address return values for the input function
- * - Check next_in and next_out for Z_NULL on entry to inflate()
- *
- * The history for versions after 1.2.0 are in ChangeLog in zlib distribution.

-   inflate() uses a state machine to process as much input data and generate as
-   much output data as possible before returning.  The state machine is
-   structured roughly as follows:
-
-    for (;;) switch (state) {
-    ...
-    case STATEn:
-        if (not enough input data or output space to make progress)
-            return;
-        ... make progress ...
-        state = STATEm;
-        break;
-    ...
-    }
-
-   so when inflate() is called again, the same case is attempted again, and
-   if the appropriate resources are provided, the machine proceeds to the
-   next state.  The NEEDBITS() macro is usually the way the state evaluates
-   whether it can proceed or should return.  NEEDBITS() does the return if
-   the requested bits are not available.  The typical use of the BITS macros
-   is:
-
-        NEEDBITS(n);
-        ... do something with BITS(n) ...
-        DROPBITS(n);
-
-   where NEEDBITS(n) either returns from inflate() if there isn't enough
-   input left to load n bits into the accumulator, or it continues.  BITS(n)
-   gives the low n bits in the accumulator.  When done, DROPBITS(n) drops
-   the low n bits off the accumulator.  INITBITS() clears the accumulator
-   and sets the number of available bits to zero.  BYTEBITS() discards just
-   enough bits to put the accumulator on a byte boundary.  After BYTEBITS()
-   and a NEEDBITS(8), then BITS(8) would return the next byte in the stream.
-
-   NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return
-   if there is no input available.  The decoding of variable length codes uses
-   PULLBYTE() directly in order to pull just enough bytes to decode the next
-   code, and no more.
-
-   Some states loop until they get enough input, making sure that enough
-   state information is maintained to continue the loop where it left off
-   if NEEDBITS() returns in the loop.  For example, want, need, and keep
-   would all have to actually be part of the saved state in case NEEDBITS()
-   returns:
-
-    case STATEw:
-        while (want < need) {
-            NEEDBITS(n);
-            keep[want++] = BITS(n);
-            DROPBITS(n);
-        }
-        state = STATEx;
-    case STATEx:
-
-   As shown above, if the next state is also the next case, then the break
-   is omitted.
-
-   A state may also return if there is not enough output space available to
-   complete that state.  Those states are copying stored data, writing a
-   literal byte, and copying a matching string.
-
-   When returning, a "goto inf_leave" is used to update the total counters,
-   update the check value, and determine whether any progress has been made
-   during that inflate() call in order to return the proper return code.
-   Progress is defined as a change in either strm->avail_in or strm->avail_out.
-   When there is a window, goto inf_leave will update the window with the last
-   output written.  If a goto inf_leave occurs in the middle of decompression
-   and there is no window currently, goto inf_leave will create one and copy
-   output to the window for the next call of inflate().
-
-   In this implementation, the flush parameter of inflate() only affects the
-   return code (per zlib.h).  inflate() always writes as much as possible to
-   strm->next_out, given the space available and the provided input--the effect
-   documented in zlib.h of Z_SYNC_FLUSH.  Furthermore, inflate() always defers
-   the allocation of and copying into a sliding window until necessary, which
-   provides the effect documented in zlib.h for Z_FINISH when the entire input
-   stream available.  So the only thing the flush parameter actually does is:
-   when flush is set to Z_FINISH, inflate() cannot return Z_OK.  Instead it
-   will return Z_BUF_ERROR if it has not reached the end of the stream.

-       code lengths are lens[0..codes-1].  Each length corresponds to the
-       symbols 0..codes-1.  The Huffman code is generated by first sorting the
-       symbols by length from short to long, and retaining the symbol order
-       for codes with equal lengths.  Then the code starts with all zero bits
-       for the first code of the shortest length, and the codes are integer
-       increments for the same length, and zeros are appended as the length
-       increases.  For the deflate format, these bits are stored backwards
-       from their more natural integer increment ordering, and so when the
-       decoding tables are built in the large loop below, the integer codes
-       are incremented backwards.
-

-       1..MAXBITS is interpreted as that code length.  zero means that that
-       symbol does not occur in this code.
-
-       The codes are sorted by computing a count of codes for each length,
-       creating from that a table of starting indices for each length in the
-       sorted table, and then entering the symbols in order in the sorted
-       table.  The sorted table is work[], with that space being provided by
-       the caller.
-
-       The length counts are used for other purposes as well, i.e. finding
-       the minimum and maximum length codes, determining if there are any
-       codes at all, checking for a valid set of lengths, and looking ahead
-       at length counts to determine sub-table sizes when building the

-\section{Introduction}
-
-This document is intended to help you quickly start writing C programs
-to read and write FITS files using the CFITSIO library.  It covers the
-most important CFITSIO routines that are needed to perform most types
-of operations on FITS files. For more complete information about these
-and all the other available routines in the library please refer to
-the  ``CFITSIO User's Reference Guide'', which is available from the
-CFITSIO Web site at {\tt http://heasarc.gsfc.nasa.gov/fitsio}.
-
-For more general information about the FITS data format, refer to the
-following web page:
-http://heasarc.gsfc.nasa.gov/docs/heasarc/fits.html
-
-FITS stands for Flexible Image Transport System and is the standard
-file format used to store most astronomical data files.  There are 2
-basic types of FITS files: images and tables.  FITS images often
-contain a 2-dimensional array of pixels representing an image of a
-piece of the sky, but  FITS images can also contain 1-D arrays (i.e,
-a spectrum or light curve), or  3-D arrays (a data cube), or
-even higher dimensional arrays of data.   An image may also have zero
-dimensions, in which case it is referred to as a null or empty array.
-The supported datatypes for the image arrays are 8, 16, and 32-bit
-integers, and 32 and 64-bit floating point real numbers.  Both signed
-and unsigned integers are supported.
-
-FITS tables contain rows and columns of data, similar to a
-spreadsheet.  All the values in a particular column must have the same
-datatype.  A cell of a column is not restricted to a single number, and
-instead can contain an array or vector of numbers.  There are actually
-2 subtypes of FITS tables: ASCII and binary. As the names imply,  ASCII
-tables store the data values in an ASCII representation whereas binary
-tables store the data values in a more efficient machine-readable
-binary format.  Binary tables are generally more compact and support
-more features (e.g., a wider range of datatypes, and vector columns)
-than ASCII tables.
-
-A single FITS file many contain multiple images or tables.  Each table
-or image is called a Header-Data Unit, or HDU.  The first HDU in a FITS
-file must be an image (but it may have zero axes) and is called the
-Primary Array.  Any additional HDUs in the file (which are also
-referred to as `extensions') may contain either an image or a table.
-
-Every HDU contains a header containing keyword records.  Each keyword
-record is 80 ASCII characters long and has the following format:
-
-\begin{verbatim}
-KEYWORD = value / comment string
-\end{verbatim}
-
-The keyword name can be up to 8 characters long (all uppercase).  The
-value can be either an integer or floating point number, a logical
-value (T or F), or a character string enclosed in single quotes.  Each
-header begins with a series of required keywords to describe the
-datatype and format of the following data unit, if any.  Any number of
-other optional keywords can be included in  the header to provide other
-descriptive information about the data.  For the most part, the CFITSIO
-routines automatically write the required FITS keywords for each HDU,
-so you, the programmer, usually do not need to worry about them.

-First, you should download the CFITSIO software and the set of example
-FITS utility programs from the web site at
-http://heasarc.gsfc.nasa.gov/fitsio.  The example programs illustrate
-how to perform many common types of operations on FITS files using
-CFITSIO.  They are also useful when writing a new program because it is
-often easier to take a copy of one of these utility programs as a
-template and then modify it for your own purposes, rather than writing
-the new program completely from scratch.
-
-To build the CFITSIO library on Unix platforms, `untar' the source code
-distribution file and then execute the following commands in the
-directory containing the source code:
-
-\begin{verbatim}
->  ./configure [--prefix=/target/installation/path]
->  make           (or 'make shared')
->  make install   (this step is optional)
-\end{verbatim}
-
-The optional
-'prefix' argument to configure gives the path to the directory where
-the CFITSIO library and include files should be installed via the later
-'make install' command. For example,
-
-\begin{verbatim}
->  ./configure --prefix=/usr1/local
-\end{verbatim}
-
-will cause the 'make install' command to copy the CFITSIO libcfitsio file 
-to /usr1/local/lib and the necessary include files to /usr1/local/include
-(assuming of course that the  process has permission to write to these 
-directories).
-
-Pre-compiled versions of the CFITSIO DLL library are available for
-PCs.  On Macintosh machines, refer to the README.MacOS file for
-instructions on building CFITSIO using CodeWarrior.
-
-Any programs that use CFITSIO must of course be linked with the CFITSIO
-library when creating the executable file.  The exact procedure for
-linking a program depends on your software environment, but on Unix
-platforms, the command line to compile and link a program will look
-something like this:
-
-\begin{verbatim}
-gcc -o myprog myprog.c -L. -lcfitsio -lm -lnsl -lsocket
-\end{verbatim}
-
-You may not need to include all of the 'm', 'nsl', and 'socket' system
-libraries on your particular machine.  To find out what libraries are
-required on your (Unix) system, type {\tt'make testprog'} and see what
-libraries are then included on the resulting link line.
-

-\section{Example Programs}
-
-Before describing the individual CFITSIO routines in detail, it is
-instructive to first look at an actual program.  The names of the
-CFITSIO routines are fairly descriptive (they all begin with {\tt
-fits\_}, so it should be reasonably clear what this program does:
-
-\begin{verbatim}
-----------------------------------------------------------------
-    #include <string.h>
-    #include <stdio.h>
-1:  #include "fitsio.h"
-
-    int main(int argc, char *argv[])
-    {
-2:      fitsfile *fptr;         
-        char card[FLEN_CARD]; 
-3:      int status = 0,  nkeys, ii;  /* MUST initialize status */
-
-4:      fits_open_file(&fptr, argv[1], READONLY, &status);
-        fits_get_hdrspace(fptr, &nkeys, NULL, &status);
-
-        for (ii = 1; ii <= nkeys; ii++)  { 
-          fits_read_record(fptr, ii, card, &status); /* read keyword */
-          printf("%s\n", card);
-        }
-        printf("END\n\n");  /* terminate listing with END */
-        fits_close_file(fptr, &status);
-
-        if (status)          /* print any error messages */
-5:          fits_report_error(stderr, status);
-        return(status);
-    }
-----------------------------------------------------------------
-\end{verbatim}
-
-This program opens the specified FITS file and prints
-out all the header keywords in the current HDU.
-Some other points to notice about the program are:
-\begin{enumerate}
-
-\item
-The {\tt fitsio.h} header file must be included to define the 
-various routines and symbols used in CFITSIO.
-
-\item
-
-The {\tt fitsfile}  parameter is the first argument in almost every
-CFITSIO routine.  It is a pointer to a structure (defined in {\tt
-fitsio.h}) that stores information about the particular FITS file that
-the routine will operate on.  Memory for this structure is
-automatically allocated when the file is first opened or created, and
-is freed when the file is closed.
-
-\item
-Almost every CFITSIO routine has a {\tt status} parameter as the last
-argument. The status value is also usually returned as the value of the
-function itself.  Normally status = 0, and a positive status value
-indicates an error of some sort.  The status variable must always be
-initialized to zero before use, because if status is greater than zero
-on input then the CFITSIO routines will simply return without doing
-anything.  This `inherited status' feature, where each CFITSIO routine
-inherits the status from the previous routine, makes it unnecessary to
-check the status value after every single CFITSIO routine call.
-Generally you should check the status after an especially important or
-complicated routine has been called, or after a block of
-closely related CFITSIO calls.  This example program has taken this
-feature to the extreme and only checks the status value at the 
-very end of the program.
-
-\item
-
-In this example program the file name to be opened is given as an
-argument on the command line ({\tt arg[1]}).  If the file contains more
-than 1 HDU or extension, you can specify which particular HDU to be
-opened by enclosing the name or number of the HDU in square brackets
-following the root name of the file.  For example, {\tt file.fts[0]}
-opens the  primary array, while {\tt file.fts[2]} will move to and open
-the 2nd extension in the file, and {\tt file.fit[EVENTS]} will open the
-extension that has a {\tt EXTNAME = 'EVENTS'} keyword in the header.
-Note that on the Unix command line you must enclose the file name in
-single or double quote characters if the name contains special
-characters such as `[' or `]'.
-
-All of the CFITSIO routines which read or write header keywords,
-image data, or table data operate only within the currently opened
-HDU in the file. To read or write information in a different HDU you must
-first explicitly move to that HDU (see the {\tt fits\_movabs\_hdu} and
-{\tt fits\_movrel\_hdu} routines in section 4.3).
-
-\item
-
-The {\tt fits\_report\_error} routine provides a convenient way to print out
-diagnostic messages about any error that may have occurred. 
-
-\end{enumerate}
-
-A set of example FITS utility programs are  available from the CFITSIO
-web site at \newline
-http://heasarc.gsfc.nasa.gov/docs/software/fitsio/cexamples.html.
-These are real working programs which illustrate how to read, write,
-and modify FITS files using the CFITSIO library.  Most of these
-programs are very short, containing only a few 10s of lines of
-executable code or less, yet they perform quite useful operations on
-FITS files. Running each program without any command line arguments
-will produce a short description of how to use the program.
-The currently available programs are:
-\begin{quote}
-fitscopy - copy a file
-\newline
-listhead - list header keywords
-\newline
-liststruc - show the structure of a FITS file.
-\newline
-modhead  - write or modify a header keyword
-\newline
-imarith  - add, subtract, multiply, or divide 2 images
-\newline
-imlist  - list pixel values in an image
-\newline
-imstat  - compute mean, min, and max pixel values in an image
-\newline
-tablist - display the contents of a FITS table
-\newline
-tabcalc  - general table calculator
-\end{quote}

-\section{CFITSIO Routines}
-
-This chapter describes the main CFITSIO routines that can be used to
-perform the most common types of operations on FITS files.
-
-% ===================================================================
-{\bf \subsection{Error Reporting}}
-
-\begin{verbatim}
-void fits_report_error(FILE *stream, int status)
-void fits_get_errstatus(int status, char *err_text)
-float fits_get_version(float *version)
-\end{verbatim}
-
-The first routine prints out information about any error that
-has occurred.  Whenever any CFITSIO routine encounters an error it
-usually writes a message describing the nature of the error to an
-internal error message stack and then returns with a positive integer
-status value. Passing the error status value to this routine will
-cause  a generic description of the error and all the messages
-from the internal CFITSIO error stack to be printed to the specified
-stream.  The {\tt stream} parameter is usually set equal to
-{\tt "stdout"} or {\tt "stderr"}.
-
-The second routine simply returns a 30-character descriptive
-error message corresponding to the input status value.
-
-The last routine returns the current CFITSIO library version number.
-
-% ===================================================================
-{\bf \subsection{File Open/Close Routines}}
-
-\begin{verbatim}
-int fits_open_file( fitsfile **fptr, char *filename, int mode, int *status)
-int fits_open_data( fitsfile **fptr, char *filename, int mode, int *status)
-int fits_open_table(fitsfile **fptr, char *filename, int mode, int *status)
-int fits_open_image(fitsfile **fptr, char *filename, int mode, int *status)
-
-int fits_create_file(fitsfile **fptr, char *filename, int *status)
-int fits_close_file(fitsfile *fptr, int *status)
-\end{verbatim}
-
-These routines open or close a file.  The first {\tt fitsfile}
-parameter  in these and nearly every other CFITSIO routine is a pointer
-to a structure that CFITSIO uses to store relevant parameters about
-each opened file.  You should never directly read or write any
-information in this structure.  Memory for this structure is allocated
-automatically when the file is opened or created, and is freed when the
-file is closed.
-
-The {\tt mode} parameter in the {\tt fits\_open\_xxxx} set of routines
-can be set to either {\tt READONLY} or {\tt READWRITE} to select the
-type of file access that will be allowed. These symbolic constants are
-defined in {\tt fitsio.h}.
-
-The {\tt fits\_open\_file} routine opens the file and positions the internal
-file pointer to the beginning of the file, or to the specified
-extension if an extension name or number is appended to the file name
-(see the later section on ``CFITSIO File Names and Filters'' for a
-description of the syntax). {\tt fits\_open\_data} behaves similarly except
-that it will move to the first HDU containing significant data if a HDU
-name or number to open is not explicitly specified as part of the
-filename.  It will move to the first IMAGE HDU with NAXIS greater than
-0, or the first table that does not contain the strings `GTI' (a Good
-Time Interval extension) or `OBSTABLE' in the EXTNAME keyword value.
-The {\tt fits\_open\_table} and {\tt fits\_open\_image}  routines are similar
-except that they will move to the first significant table HDU or image
-HDU, respectively if a HDU name of number is not specified as part of
-the input file name.
-
-When opening an existing file, the {\tt filename} can include optional
-arguments, enclosed in square brackets that specify filtering
-operations that should be applied to the input file.  For example,
-\begin{verbatim}
-   myfile.fit[EVENTS][counts > 0]
-\end{verbatim}
-opens the table in the EVENTS extension and creates a virtual table by
-selecting only those rows where the COUNTS column value is greater than
-0.  See section 5 for more examples of these powerful filtering
-capabilities.
-
-In {\tt fits\_create\_file},  the {\tt filename} is simply the root name of
-the file to be created.  You can overwrite an existing file by
-prefixing the name with a `!' character (on the Unix command line this
-must be prefixed with a backslash, as in \verb+`\!file.fit'+).  
-If the file name ends with {\tt .gz} the file will be compressed
-using the gzip algorithm.  If the
-filename is {\tt stdout} or {\tt "-"} (a single dash character)
-then the output file will be piped to the stdout stream.  You can
-chain several tasks together by writing the output from the first task
-to {\tt stdout} and then reading the input file in the 2nd task from
-{\tt stdin} or {\tt "-"}.
-
-
-% ===================================================================
-{\bf \subsection{HDU-level Routines}}
-
-The routines listed in this section operate on Header-Data Units (HDUs) in a file.
-
-\begin{verbatim}
-_______________________________________________________________
-int fits_get_num_hdus(fitsfile *fptr, int *hdunum, int *status)
-int fits_get_hdu_num(fitsfile *fptr,  int *hdunum)
-\end{verbatim}
-
-The first routines returns the total number of HDUs in the FITS file,
-and the second routine returns the position of the currently opened HDU in
-the FITS file (starting with 1, not 0).
-
-\begin{verbatim}
-__________________________________________________________________________
-int fits_movabs_hdu(fitsfile *fptr, int hdunum, int *hdutype, int *status)
-int fits_movrel_hdu(fitsfile *fptr, int nmove,  int *hdutype, int *status)
-int fits_movnam_hdu(fitsfile *fptr, int hdutype, char *extname,
-                    int extver, int *status)
-\end{verbatim}
-
-These routines enable you to move to a different HDU in the file.
-Most of the CFITSIO functions which read or write keywords or data
-operate only on the currently opened HDU in the file.  The first
-routine moves to the specified absolute HDU number in the FITS
-file (the first HDU = 1), whereas the second routine moves a relative
-number of HDUs forward or backward from the currently open HDU.  The
-{\tt hdutype} parameter returns the type of the newly opened HDU, and will
-be equal to one of these symbolic constant values: {\tt IMAGE\_HDU,
-ASCII\_TBL, or BINARY\_TBL}.  {\tt hdutype} may be set to NULL
-if it is not needed.  The third routine moves to the (first) HDU
-that matches the input extension type, name, and version number,
-as given by the {\tt XTENSION, EXTNAME} (or {\tt HDUNAME}) and {\tt EXTVER} keywords.
-If the input value of {\tt extver} = 0, then the version number will
-be ignored when looking for a matching HDU.
-
-\begin{verbatim}
-_________________________________________________________________
-int fits_get_hdu_type(fitsfile *fptr,  int *hdutype, int *status)
-\end{verbatim}
-
-Get the type of the current HDU in the FITS file:  {\tt IMAGE\_HDU,
-ASCII\_TBL, or BINARY\_TBL}.
-
-\begin{verbatim}
-____________________________________________________________________
-int fits_copy_hdu(fitsfile *infptr, fitsfile *outfptr, int morekeys,
-                  int *status)
-int fits_copy_file(fitsfile *infptr, fitsfile *outfptr, int previous,
-                  int current, int following, > int *status)
-\end{verbatim}
-
-The first routine copies the current HDU from the FITS file associated
-with infptr and appends it to the end of the FITS file associated with
-outfptr.  Space may be reserved for {\tt morekeys} additional keywords
-in the output header.   The second routine copies any HDUs previous
-to the current HDU, and/or the current HDU, and/or any HDUs following the
-current HDU, depending on the value (True or False) of {\tt previous,
-current}, and {\tt following}, respectively.  For example,
-\begin{verbatim}
-  fits_copy_file(infptr, outfptr, 0, 1, 1, &status);
-\end{verbatim}
-will copy the current HDU and any HDUs that follow it from the input
-to the output file, but it will not copy any HDUs preceding the 
-current HDU.
-
-
-\newpage
-% ===================================================================
-\subsection{Image I/O Routines}
-
-This section lists the more important CFITSIO routines which operate on
-FITS images.
-
-\begin{verbatim}
-_______________________________________________________________
-int fits_get_img_type(fitsfile *fptr, int *bitpix, int *status)
-int fits_get_img_dim( fitsfile *fptr, int *naxis,  int *status)
-int fits_get_img_size(fitsfile *fptr, int maxdim,  long *naxes,
-                      int *status)
-int fits_get_img_param(fitsfile *fptr, int maxdim,  int *bitpix,
-                       int *naxis, long *naxes, int *status)
-\end{verbatim}
-
-Get information about the currently opened image HDU. The first routine
-returns the datatype of the image as (defined by the {\tt BITPIX}
-keyword), which can have the following symbolic constant values: 
-\begin{verbatim}
-    BYTE_IMG   =   8   ( 8-bit byte pixels, 0 - 255)
-    SHORT_IMG  =  16   (16 bit integer pixels)
-    LONG_IMG   =  32   (32-bit integer pixels)
-    FLOAT_IMG  = -32   (32-bit floating point pixels)
-    DOUBLE_IMG = -64   (64-bit floating point pixels)
-\end{verbatim}
-
-The second and third routines return the number of dimensions in the
-image (from the {\tt NAXIS} keyword), and the sizes of each dimension
-(from the {\tt NAXIS1, NAXIS2}, etc. keywords).  The last routine
-simply combines the function of the first 3 routines.  The input {\tt
-maxdim} parameter in this routine gives the maximum number dimensions
-that may be returned (i.e., the dimension of the {\tt naxes}
-array)
-
-\begin{verbatim}
-__________________________________________________________
-int fits_create_img(fitsfile *fptr, int bitpix, int naxis, 
-                    long *naxes, int *status)
-\end{verbatim}
-
-Create an image HDU by writing the required keywords which define the
-structure of the image.  The 2nd through 4th parameters  specified the
-datatype, the number of dimensions, and the sizes of the dimensions.
-The allowed values of the {\tt bitpix} parameter are listed above in
-the description of the {\tt fits\_get\_img\_type} routine.  If the FITS
-file pointed to by {\tt fptr} is empty (previously created with
-{\tt fits\_create\_file}) then this routine creates a primary array in
-the file, otherwise a new IMAGE extension is appended to end of the
-file following the other HDUs in the file.
-
-\begin{verbatim}
-______________________________________________________________
-int fits_write_pix(fitsfile *fptr, int datatype, long *fpixel,
-               long nelements, void *array, int *status);
-
-int fits_write_pixnull(fitsfile *fptr, int datatype, long *fpixel,
-               long nelements, void *array, void *nulval, int *status);
-
-int fits_read_pix(fitsfile *fptr, int  datatype, long *fpixel, 
-                  long nelements, void *nulval, void *array, 
-                  int *anynul, int *status)
-\end{verbatim}
-
-Read or write all or part of the FITS image.  There are 2 different
-'write' pixel routines:  The first simply writes the input array of pixels
-to the FITS file.  The second is similar, except that it substitutes
-the appropriate null pixel value in the FITS file for any pixels 
-which have a value equal to {\tt *nulval} (note that this parameter
-gives the address of the null pixel value, not the value itself).
-Similarly,  when reading an image, CFITSIO will substitute the value
-given by {\tt nulval}  for  any undefined pixels in the image, unless
-{\tt nulval = NULL}, in which case no checks will be made for undefined
-pixels when reading the FITS image.
-
-The {\tt fpixel} parameter in these routines is an array which gives
-the coordinate in each dimension of the first pixel to be read or
-written, and {\tt nelements} is the total number of pixels to read or
-write.  {\tt array} is the address of an array which either contains
-the pixel values to be written, or will hold the values of the pixels
-that are read.  When reading, {\tt array} must have been allocated
-large enough to hold all the returned pixel values.  These routines
-starts at the {\tt fpixel} location and then read or write the {\tt
-nelements} pixels, continuing on successive rows of the image if
-necessary.  For example, to write an entire 2D image, set {\tt
-fpixel[0] = fpixel[1] = 1}, and {\tt nelements = NAXIS1 * NAXIS2}.  Or
-to read just the 10th row of the image, set {\tt fpixel[0] = 1,
-fpixel[1] = 10}, and {\tt nelements = NAXIS1}.  The {\tt datatype}
-parameter specifies the datatype of the C {\tt array} in the program,
-which need not be the same as the datatype of the FITS image itself.
-If the datatypes differ then CFITSIO will convert the data as it is
-read or written.  The following symbolic constants are allowed for the
-value of {\tt datatype}:
-\begin{verbatim}
-  TBYTE     unsigned char
-  TSBYTE    signed char
-  TSHORT    signed short
-  TUSHORT   unsigned short
-  TINT      signed int
-  TUINT     unsigned int
-  TLONG     signed long
-  TLONGLONG signed 8-byte integer
-  TULONG    unsigned long
-  TFLOAT    float
-  TDOUBLE   double
-\end{verbatim}
-
-
-\begin{verbatim}
-_________________________________________________________________
-int fits_write_subset(fitsfile *fptr, int datatype, long *fpixel,
-             long *lpixel, DTYPE *array, > int *status)
-
-int fits_read_subset(fitsfile *fptr, int  datatype, long *fpixel,
-             long *lpixel, long *inc, void *nulval,  void *array,
-             int *anynul, int *status)
-\end{verbatim}
-
-Read or write a rectangular section of the FITS image.  These are very
-similar to {\tt fits\_write\_pix} and {\tt fits\_read\_pix} except that
-you specify the last pixel coordinate (the upper right corner of the
-section) instead of the number of pixels to be read.  The read routine
-also has an {\tt inc} parameter which can be used to read only every
-{\tt inc-th} pixel along each dimension of the image.  Normally  {\tt
-inc[0] = inc[1] = 1} to read every pixel in a 2D image.  To read every
-other pixel in the entire 2D image, set
-\begin{verbatim}
-    fpixel[0] = fpixel[1] = 1
-    lpixel[0] = {NAXIS1}
-    lpixel[1] = {NAXIS2}  
-    inc[0] = inc[1] = 2  
-\end{verbatim}
-
-Or, to read the 8th row of a 2D image, set 
-\begin{verbatim}
-    fpixel[0] = 1
-    fpixel[1] = 8
-    lpixel[0] = {NAXIS1}
-    lpixel[1] = 8
-    inc[0] = inc[1] = 1
-\end{verbatim}
-

-\subsection{Table I/O Routines}
-
-This section lists the most important CFITSIO routines which operate on
-FITS tables.
-
-\begin{verbatim}
-__________________________________________________________________________
-int fits_create_tbl(fitsfile *fptr, int tbltype, long nrows, int tfields,
-    char *ttype[],char *tform[], char *tunit[], char *extname, int *status)
-\end{verbatim}
-
-Create a new  table extension by writing the required keywords that
-define the table structure. The required null primary array
-will be created first if the file is initially completely empty.  {\tt
-tbltype} defines the type of table and can have values of {\tt
-ASCII\_TBL or BINARY\_TBL}.  Binary tables are generally preferred
-because they are more efficient and support a greater range of column
-datatypes than ASCII tables.
-
-The {\tt nrows} parameter gives the initial number of empty rows to be
-allocated for the table; this should normally be set to 0.  The {\tt tfields}
-parameter gives the number of columns in the table (maximum = 999).
-The {\tt
-ttype, tform}, and {\tt tunit} parameters give the name, datatype, and
-physical units of each column, and {\tt extname} gives the name for the
-table (the value of the {\tt EXTNAME} keyword).  
-The FITS Standard recommends that only
-letters, digits, and the underscore character be used in column names
-with no embedded spaces.  It is recommended that all the column names
-in a given table be unique within the first 8 characters.
-
-The following table
-shows the TFORM column format values that are allowed in ASCII tables
-and in binary tables:
-\begin{verbatim}
-        ASCII Table Column Format Codes
-        -------------------------------
-        (w = column width, d = no. of decimal places to display)
-            Aw   - character string
-            Iw   - integer
-            Fw.d - fixed floating point
-            Ew.d - exponential floating point
-            Dw.d - exponential floating point
-
-        Binary Table Column Format Codes
-        --------------------------------
-        (r = vector length, default = 1)
-            rA  - character string
-            rAw - array of strings, each of length w
-            rL  - logical
-            rX  - bit
-            rB  - unsigned byte
-            rS  - signed byte **
-            rI  - signed 16-bit integer
-            rU  - unsigned 16-bit integer **
-            rJ  - signed 32-bit integer
-            rV  - unsigned 32-bit integer **
-            rK  - 64-bit integer ***
-            rE  - 32-bit floating point
-            rD  - 64-bit floating point
-            rC  - 32-bit complex pair
-            rM  - 64-bit complex pair
-
-     ** The S, U and V format codes are not actual legal TFORMn values.
-        CFITSIO substitutes the somewhat more complicated set of
-        keywords that are used to represent unsigned integers or
-        signed bytes.
-
-    *** The 64-bit integer format is experimental and is not 
-        officially recognized in the FITS Standard.

-Return the datatype, vector repeat count, and the width in bytes of a
-single column element for column number {\tt colnum}.  Allowed values
-for the returned datatype in ASCII tables are:  {\tt TSTRING, TSHORT,
-TLONG, TFLOAT, and TDOUBLE}.  Binary tables support these additional
-types: {\tt TLOGICAL, TBIT, TBYTE, TINT32BIT, TCOMPLEX and TDBLCOMPLEX}.  The
-negative of the datatype code value is returned if it is a variable
-length array column.
-
-These 2 routines are similar, except that in the case of scaled
-integer columns the 2nd routine, fit\_get\_eqcoltype, returns the
-'equivalent' datatype that is needed to store the scaled values, which
-is not necessarily the same as the physical datatype of the unscaled values
-as stored in the FITS table.  For example if a '1I' column in a binary
-table has TSCALn = 1 and TZEROn = 32768, then this column effectively
-contains unsigned short integer values, and thus the returned value of
-typecode will be TUSHORT, not TSHORT.  Or, if TSCALn or TZEROn are not
-integers, then the equivalent datatype will be returned as TFLOAT or
-TDOUBLE, depending on the size of the integer.
-
-The repeat count is always 1 in ASCII tables.
-The 'repeat' parameter returns the vector repeat count on the binary
-table TFORMn keyword value. (ASCII table columns always have repeat
-= 1).  The 'width' parameter returns the width in bytes of a single
-column element (e.g., a '10D' binary table column will have width =
-8, an ASCII table 'F12.2' column will have width = 12, and a binary
-table'60A' character string  column will have width = 60);  Note that
-this routine supports the local convention for specifying arrays of
-fixed length strings within a binary table character column using
-the syntax TFORM = 'rAw' where 'r' is the total number of
-characters (= the width of the column) and 'w' is the width of a
-unit string within the column.  Thus if the column has TFORM =
-'60A12' then this means that each row of the table contains
-5 12-character substrings within the 60-character field, and thus 
-in this case this routine will return typecode = TSTRING, repeat =
-60, and width = 12.  The number of substings in any binary table
-character string field can be calculated by (repeat/width). 
-A null pointer may be given for any of the output parameters that
- are not needed.

-column).  {\tt firstelem} is ignored if it is a scalar column. The {\tt

-of an array which either contains the  values to be written, or will
-hold the returned values that are read.  When reading, {\tt array} must
-have been allocated large enough to hold all the returned values.
-
-There are 3 different 'write' column routines:  The first simply writes

-substitutes the appropriate null pixel value in the column for any
-input array values which are equal to {\tt *nulval} (note that this
-parameter gives the address of the null pixel value, not the value
-itself).  The third write routine sets the specified table elements
-to a null value.  New rows will be automatical added to the table
-if the write operation extends beyond the current size of the table.
-
-When reading a column, CFITSIO will substitute the value given by {\tt
-nulval}  for  any undefined elements in the FITS column, unless {\tt
-nulval} or {\tt *nulval = NULL}, in which case no checks will be made
-for undefined values when reading the column.
-
-{\tt datatype} specifies the datatype of the C {\tt array} in the program,
-which need not be the same as the intrinsic datatype of the column in
-the FITS table.   The following symbolic constants are allowed for the
-value of {\tt datatype}:
-
-\begin{verbatim}
-  TSTRING   array of character string pointers
-  TBYTE     unsigned char
-  TSHORT    signed short
-  TUSHORT   unsigned short
-  TINT      signed int
-  TUINT     unsigned int
-  TLONG     signed long
-  TLONGLONG signed 8-byte integer
-  TULONG    unsigned long
-  TFLOAT    float
-  TDOUBLE   double
-\end{verbatim}
-
-Note that {\tt TSTRING} corresponds to the C {\tt
-char**} datatype, i.e., a pointer to an array of pointers to an array
-of characters.
-
-Any column, regardless of it's intrinsic datatype, may be read as a
-{\tt TSTRING} character string. The display format of the returned
-strings will be determined by the {\tt TDISPn} keyword, if it exists,
-otherwise a default format will be used depending on the datatype of
-the column.  The {\tt tablist} example utility program (available from
-the CFITSIO web site) uses this feature to display all the values in a
-FITS table.

-These are 2 of the most powerful routines in the CFITSIO library.  (See
-the full CFITSIO Reference Guide for a description of several related
-routines).  These routines can perform complicated transformations on
-tables based on an input arithmetic expression which is evaluated for
-each row of the table.  The first routine will select or copy rows of
-the table for which the expression evaluates to TRUE (i.e., not equal
-to zero).  The second routine writes the value of the expression to a
-column in the output table.  Rather than supplying the expression
-directly to these routines, the expression may also be written to a
-text file (continued over multiple lines if necessary) and the name of
-the file, prepended with a '@' character, may be supplied as the value
-of the 'expr' parameter (e.g.  '@filename.txt').
-
-The arithmetic expression may be a function of any column or keyword in
-the input table as shown in these examples:
-
-\begin{verbatim}
-Row Selection Expressions:
-   counts > 0                          uses COUNTS column value
-   sqrt( X**2 + Y**2) < 10.            uses X and Y column values
-   (X > 10) || (X < -10) && (Y == 0)   used 'or' and 'and' operators  
-   gtifilter()                         filter on Good Time Intervals
-   regfilter("myregion.reg")           filter using a region file
-   @select.txt                         reads expression from a text file
-Calculator Expressions:
-   #row % 10                        modulus of the row number
-   counts/#exposure                 Fn of COUNTS column and EXPOSURE keyword
-   dec < 85 ? cos(dec * #deg) : 0   Conditional expression: evaluates to
-                                      cos(dec) if dec < 85, else 0
-   (count{-1}+count+count{+1})/3.   running mean of the count values in the

-   max(0, min(X, 1000))             returns a value between 0 - 1000
-   @calc.txt                        reads expression from a text file
-\end{verbatim}
-
-Most standard mathematical operators and functions are supported.  If
-the expression includes the name of a column, than the value in the
-current row of the table will be used when evaluating the expression on
-each row.   An offset to an adjacent row can be specified by including
-the offset value in curly brackets after the column name as shown in
-one of the examples.  Keyword values can be included in the expression
-by preceding the keyword name with a `\#' sign.   See Section 5 of this
-document for more discussion of the expression syntax.
-
-{\tt gtifilter} is a special function which tests whether the {\tt
-TIME} column value in the input table falls within one or more Good
-Time Intervals.  By default, this function looks for a 'GTI' extension
-in the same file as the input table.  The 'GTI' table contains {\tt START} 
-and {\tt STOP} columns which define the range of
-each good time interval. See section 5.4.3 for more details.
-
-{\tt regfilter} is another special function which selects rows based on
-whether the spatial position associated with each row is located within
-in a specified region of the sky.  By default, the {\tt X} and {\tt Y}
-columns in the input table are assumed to give the position of each row.
-The spatial region is defined in an ASCII text file whose name is given
-as the argument to the {\tt regfilter} function. See section 5.4.4 for
-more details.
-
-The {\tt infptr} and {\tt outfptr} parameters in these routines may
-point to the same table or to different tables.  In {\tt
-fits\_select\_rows}, if the input and output tables are the same then
-the rows that do not satisfy the selection expression will be deleted
-from the table.  Otherwise, if the output table is different from the
-input table then the selected rows will be copied from the input table
-to the output table.
-
-The output column in {\tt fits\_calculator} may or may not already
-exist.  If it exists then the calculated values will be written to that
-column, overwriting the existing values.  If the column doesn't exist
-then the new column will be appended to the output table. The {\tt tform}
-parameter can be used to specify the datatype of the new column (e.g.,
-the {\tt TFORM} keyword value as in {\tt '1E', or '1J'}). If {\tt
-tform} = NULL then a default datatype will be used, depending on the
-expression.

-These 2 routines provide low-level access to tables and are mainly
-useful as an efficient way to copy rows of a table from one file to

-consecutive characters (bytes) in a table, without regard for column
-boundaries.  For example, to read or write the first row of a table,
-set {\tt firstrow = 1, firstchar = 1}, and {\tt nchars = NAXIS1} where
-the length of a row is given by the value of the {\tt NAXIS1} header

-
-These routines all read a header record in the current HDU. The first
-routine reads keyword number {\tt keynum} (where the first keyword is
-at position 1).  This routine is most commonly used when sequentially
-reading every record in the header from beginning to end.  The 2nd and
-3rd routines read the named keyword and return either the whole
-record, or the keyword value and comment string.  In each case any 
-non-significant trailing blank characters in the strings are truncated.
-
-Wild card characters (*, ?, and \#) may be used when specifying the name
-of the keyword to be read, in which case the first matching keyword is
-returned.
-
-The {\tt datatype} parameter specifies the C datatype of the returned
-keyword value and can have one of the following symbolic constant
-values:  {\tt TSTRING, TLOGICAL} (== int), {\tt TBYTE}, {\tt TSHORT},
-{\tt TUSHORT}, {\tt TINT}, {\tt TUINT}, {\tt TLONG}, {\tt TULONG}, {\tt
-TFLOAT}, {\tt TDOUBLE}, {\tt TCOMPLEX}, and {\tt TDBLCOMPLEX}.  Data
-type conversion will be performed for numeric values if the intrinsic
-FITS keyword value does not have the same datatype.  The {\tt comment}
-parameter may be set equal to NULL if the comment string is not
-needed.
-
-The 4th routine provides an easy way to find all the keywords in the
-header that match one of the name templates in {\tt inclist} and do not
-match any of the name templates in {\tt exclist}.  {\tt ninc} and {\tt
-nexc} are the number of template strings in {\tt inclist} and {\tt

-templates to match multiple keywords.  Each time this routine is called
-it returns the next matching 80-byte keyword record.  It returns status

-Write or modify a keyword  in the header of the current HDU.  The
-first routine appends the new keyword to the end of the header, whereas
-the second routine will update the value and comment fields of the
-keyword if it already exists, otherwise it behaves like the first
-routine and appends the new keyword.  Note that {\tt value} gives the
-address to the value and not the value itself.  The {\tt datatype}
-parameter specifies the C datatype of the keyword value and may have
-any of the values listed in the description of the keyword reading
-routines, above.  A NULL may be entered for the comment parameter, in
-which case the  keyword comment field will be unmodified or left

-The third routine is more primitive and simply writes the 80-character
-{\tt card} record to the header.  It is the programmer's responsibility
-in this case to ensure that the record conforms to all the FITS format
-requirements for a header record.

-
-Write a {\tt COMMENT, HISTORY}, or {\tt DATE} keyword to the current
-header.  The {\tt COMMENT} keyword is typically used to write a comment
-about the file or the data.  The {\tt HISTORY} keyword is typically
-used to provide information about the history of the processing
-procedures that have been applied to the data.  The {\tt comment} or
-{\tt history} string will be continued over multiple keywords if it is
-more than 70 characters long.
-
-The {\tt DATE} keyword is used to record the date and time that the
-FITS file was created.  Note that this file creation date is usually
-different from the date of the observation which obtained the data in
-the FITS file.  The {\tt DATE} keyword value is a character string in
-'yyyy-mm-ddThh:mm:ss' format. If a {\tt DATE} keyword already exists in

-
-These routines  compute or validate the checksums for the currenrt
-HDU.  The {\tt DATASUM} keyword is used to store the numerical value of
-the 32-bit, 1's complement checksum for the data unit alone.  The {\tt
-CHECKSUM} keyword is used to store the ASCII encoded COMPLEMENT of the
-checksum for the entire HDU.  Storing the complement, rather than the
-actual checksum, forces the checksum for the whole HDU to equal zero.
-If the file has been modified since the checksums were computed, then
-the HDU checksum will usually not equal zero.
-
-The returned {\tt dataok} and {\tt hduok} parameters will have a value

-{\tt fits\_parse\_value} parses the input 80-chararacter header keyword record, returning
-the value (as a literal character string) and comment strings.  If the

-value string is returned and the comment string is set equal to column
-9 - 80 of the input string.
-
-{\tt fits\_get\_keytype} parses the keyword value string to determine its
-datatype.  {\tt dtype} returns with a value of 'C', 'L', 'I', 'F' or
-'X', for character string, logical, integer, floating point, or
-complex, respectively.
-
-{\tt fits\_get\_keyclass} returns a classification code that indicates

-etc.  See the CFITSIO Reference Guide for a list of the different

-
-{\tt fits\_parse\_template} takes an input free format keyword template
-string and returns a formatted 80*char record that satisfies all the
-FITS requirements for a header keyword record.  The template should
-generally contain 3 tokens: the keyword name, the keyword value, and
-the keyword comment string.  The returned {\tt keytype} parameter
-indicates whether the keyword is a COMMENT keyword or not.   See the
-CFITSIO Reference Guide for more details.

-\section{CFITSIO File Names and Filters}
-
-\subsection{Creating New Files}
-
-When creating a new output file on magnetic disk  with {\tt
-fits\_create\_file} the following features are supported.
-\begin{itemize}
-\item Overwriting, or 'Clobbering' an Existing File
-
-If the filename is preceded by an exclamation
-point (!) then if that file already exists it will be deleted prior to
-creating the new FITS file.  Otherwise if there is an existing file
-with the same name, CFITSIO will not overwrite the existing file and
-will return an error status code.  Note  that the exclamation point is
-a special UNIX character, so if it is used on the command line rather
-than entered at a task prompt, it must be preceded by a backslash to
-force the UNIX shell to pass it verbatim to the application program.
-
-\item Compressed Output Files
-
-If the output disk file name ends with the suffix '.gz', then CFITSIO
-will compress the file using the gzip compression algorithm before
-writing it to disk.  This can reduce the amount of disk space used by
-the file.  Note that this feature requires that the uncompressed file
-be constructed in memory before it is compressed and written to disk,
-so it can fail if there is insufficient available memory.
-
-One can also specify that any images written to the output file should
-be compressed using the newly developed `tile-compression' algorithm by
-appending `[compress]' to the name of the disk file (as in
-{\tt myfile.fits[compress]}).   Refer to the CFITSIO User's Reference Guide
-for more information about this new image compression format.
-
-\item Using a Template to Create a New FITS File
-
-The structure of any new FITS file that is to be created may be defined
-in an ASCII template file.  If the name of the template file is
-appended to the name of the FITS file itself, enclosed in parenthesis
-(e.g., {\tt 'newfile.fits(template.txt)'}) then CFITSIO will create a
-FITS file with that structure before opening it for the application to
-use.  The template file basically defines the dimensions and data type
-of the primary array and any IMAGE extensions, and the names and data
-types of the columns in any ASCII or binary table extensions.  The
-template file can also be used to define any optional keywords that
-should be written in any of the HDU headers.  The image pixel values
-and table entry values are all initialized to zero.  The application
-program can then write actual data into the HDUs.  See the CFITSIO
-Reference Guide for for a complete description of the template file
-syntax.
-
-\item Creating a Temporary Scratch File in Memory
-
-It is sometimes useful to create a temporary output file when testing
-an application program.  If the name of the file to be created is
-specified as {\tt mem:} then CFITSIO will create the file in
-memory where it will persist only until the program closes the file.
-Use of this {\tt mem:} output file usually enables the program to run
-faster, and of course the output file does not use up any disk space.
-
-
-\end{itemize}
-
-\subsection{Opening Existing Files}
-
-When opening a file with {\tt fits\_open\_file}, CFITSIO can read a
-variety of different input file formats and is not restricted to only
-reading FITS format files from magnetic disk. The following types of
-input files are all supported:
-
-\begin{itemize}
-\item FITS files compressed with {\tt zip, gzip} or {\tt compress}
-
-If CFITSIO cannot find the specified file to open it will automatically
-look for a file with the same rootname but with a {\tt .gz, .zip}, or
-{\tt .Z} extension.  If it finds such a compressed file, it will
-allocate a block of memory and uncompress the file into that memory
-space.  The application program will then transparently open this
-virtual FITS file in memory.  Compressed
-files can only be opened with 'readonly', not 'readwrite' file access.
-
-\item  FITS files on the internet, using {\tt ftp} or {\tt http} URLs
-
-Simply provide the full URL as the name of the file that you want to
-open.  For example,\linebreak {\tt
-ftp://legacy.gsfc.nasa.gov/software/fitsio/c/testprog.std}\linebreak
-will open the CFITSIO test FITS file that is located on the {\tt
-legacy} machine.  These files can only be opened with 'readonly' file
-access.
-
-\item  FITS files on {\tt stdin} or {\tt stdout} file streams
-
-If the name of the file to be opened is {\tt 'stdin'} or {\tt '-'} (a
-single dash character) then CFITSIO will read the file from the
-standard input stream.  Similarly, if the output file name is {\tt
-'stdout'} or {\tt '-'}, then the file will be written to the standard
-output stream.  In addition, if the output filename is {\tt
-'stdout.gz'} or {\tt '-.gz'} then it will be gzip compressed before
-being written to stdout.  This mechanism can be used to pipe FITS files
-from one task to another without having to write an intermediary FITS
-file on magnetic disk.
-
-\item FITS files that exist only in memory, or shared memory.
-
-In some applications, such as real time data acquisition, you may want
-to have one process write a FITS file into a certain section of
-computer memory, and then be able to open that file in memory with
-another process.  There is a specialized CFITSIO open routine called
-{\tt fits\_open\_memfile} that can be used for this purpose.  See the
-``CFITSIO User's Reference Guide'' for more details.
-
-\item  IRAF format images (with {\tt .imh} file extensions)
-
-CFITSIO supports reading IRAF format images by converting them on the
-fly into FITS images in memory.  The application program then reads
-this virtual FITS format image in memory.  There is currently no
-support for writing IRAF format images, or for reading or writing IRAF
-tables.
-
-\item Image arrays in raw binary format
-
-If the input file is a raw binary data array, then CFITSIO will convert
-it on the fly into a virtual FITS image with the basic set of required
-header keywords before it is opened by the application program.  In
-this case the data type and dimensions of the image must be specified
-in square brackets following the filename (e.g. {\tt
-rawfile.dat[ib512,512]}). The first character inside the brackets
-defines the datatype of the array:
-
-\begin{verbatim}
-     b         8-bit unsigned byte
-     i        16-bit signed integer
-     u        16-bit unsigned integer
-     j        32-bit signed integer
-     r or f   32-bit floating point
-     d        64-bit floating point
-\end{verbatim}
-An optional second character specifies the byte order of the array
-values: b or B indicates big endian (as in FITS files and the native
-format of SUN UNIX workstations and Mac PCs) and l or L indicates
-little endian (native format of DEC OSF workstations and IBM PCs).  If
-this character is omitted then the array is assumed to have the native
-byte order of the local machine.  These datatype characters are then
-followed by a series of one or more integer values separated by commas
-which define the size of each dimension of the raw array.  Arrays with
-up to 5 dimensions are currently supported.  
-
-Finally, a byte offset to the position of the first pixel in the data
-file may be specified by separating it with a ':' from the last
-dimension value.  If omitted, it is assumed that the offset = 0.  This
-parameter may be used to skip over any header information in the file
-that precedes the binary data.  Further examples:
- 
-\begin{verbatim}
-  raw.dat[b10000]          1-dimensional 10000 pixel byte array
-  raw.dat[rb400,400,12]    3-dimensional floating point big-endian array
-  img.fits[ib512,512:2880] reads the 512 x 512 short integer array in a
-                           FITS file, skipping over the 2880 byte header
-\end{verbatim}
-
-\end{itemize}
-\newpage
-
-\subsection{Image Filtering}
-
-\subsubsection{Extracting a subsection of an image}
-
-When specifying the name of an image to be opened, you can select a
-rectangular subsection of the image to be extracted and opened by the
-application program.  The application program then opens a virtual
-image that only contains the pixels within the specified subsection.
-To do this, specify the the range of pixels (start:end) along each axis
-to be extracted from the original image enclosed in square brackets.
-You can also specify an optional pixel increment (start:end:step) for
-each axis of the input image.  A pixel step = 1 will be assumed if it
-is not specified.  If the starting pixel is larger then the end pixel,
-then the image will be flipped (producing a mirror image) along that
-dimension.  An asterisk, '*', may be used to specify the entire range
-of an axis, and '-*' will flip the entire axis.  In the following
-examples, assume that {\tt myfile.fits} contains a 512 x 512 pixel 2D
-image.
-
-\begin{verbatim}
-  myfile.fits[201:210, 251:260] - opens a 10 x 10 pixel subimage.
-
-  myfile.fits[*, 512:257] - opens a 512 x 256 image consisting of
-	      all the columns in the input image, but only rows 257
-	      through 512.  The image will be flipped along the Y axis
-	      since the starting row is greater than the ending
-	      row.
-
-  myfile.fits[*:2, 512:257:2] - creates a 256 x 128 pixel image.
-	      Similar to the previous example, but only every other row
-	      and column is read from the input image.
-
-  myfile.fits[-*, *] - creates an image containing all the rows and
-	      columns in the input image, but flips it along the X
-	      axis.
-\end{verbatim}
-
-If the array to be opened is in an Image extension, and not in the
-primary array of the file, then you need to specify the extension
-name or number in square brackets before giving the subsection range,
-as in {\tt  myfile.fits[1][-*, *]} to read the image in the
-first extension in the file.
-
-\subsubsection{Create an Image by Binning Table Columns}
-
-You can also create and open a virtual image by binning the values in a
-pair of columns of a FITS table (in other words, create a 2-D histogram
-of the values in the 2 columns).  This technique is often used in X-ray
-astronomy where each detected X-ray photon during an observation is
-recorded in a FITS table.  There are typically 2 columns in the table
-called  {\tt X} and {\tt Y} which record the pixel location of that
-event in a virtual 2D image.  To create an image from this table, one
-just scans the X and Y columns and counts up how many photons were
-recorded in each pixel of the image.  When table binning is specified,
-CFITSIO creates a temporary FITS primary array in memory by computing
-the histogram of the values in the specified columns.  After the
-histogram is computed the original FITS file containing the table is
-closed and the temporary FITS primary array is opened and passed to the
-application program.  Thus, the application program never sees the
-original FITS table and only sees the image in the new temporary file
-(which has no extensions).
-
-The table binning specifier is enclosed in square brackets following
-the root filename and table extension name or number and begins with
-the keyword 'bin', as in: \newline  
-{\tt 'myfile.fits[events][bin (X,Y)]'}. In
-this case, the X and Y columns in the 'events' table extension are
-binned up to create the image.  The size of the image is usually
-determined by the {\tt TLMINn} and {\tt TLMAXn} header keywords which
-give the minimum and maximum allowed pixel values in the columns.  For
-instance if {\tt TLMINn = 1} and {\tt TLMAXn = 4096} for both columns, this would
-generate a 4096 x 4096 pixel image by default.  This is rather large,
-so you can also specify a pixel binning factor to reduce the image
-size.  For example specifying ,  {\tt '[bin (X,Y) = 16]'} will use a
-binning factor of 16, which will produce a 256 x 256 pixel image in the
-previous example.
-
-If the TLMIN and TLMAX keywords don't exist, or you want to override
-their values,  you can specify the image range and binning factor
-directly, as in {\tt '[bin X = 1:4096:16, Y=1:4096:16]'}.  You can also
-specify the datatype of the created image by appending a b, i, j, r, or
-d (for 8-bit byte, 16-bit integers, 32-bit integer, 32-bit floating
-points, or 64-bit double precision floating point, respectively)  to
-the 'bin' keyword (e.g. {\tt '[binr (X,Y)]'} creates a floating point
-image).  If the datatype is not specified then a 32-bit integer image
-will be created by default.
-
-If the column name is not specified, then CFITSIO will first try to use
-the 'preferred column' as specified by the CPREF keyword if it exists
-(e.g., 'CPREF = 'DETX,DETY'), otherwise column names 'X', 'Y' will be
-assumed for the 2 axes.
-
-Note that this binning specifier is not restricted to only 2D images
-and can be used to create 1D, 3D, or 4D images as well.  It is also
-possible to specify a weighting factor that is applied during the
-binning.  Please refer to the ``CFITSIO User's Reference Guide'' for
-more details on these advanced features.

-
-\subsection{Table Filtering}
-
-\subsubsection{Column and Keyword Filtering}
-
-The column or keyword filtering specifier is used to modify the
-column structure and/or the header keywords in the HDU that was
-selected with the previous HDU location specifier.   It can
-be used to perform the following types of operations. 
-
-\begin{itemize}
-\item
-Append a new column to a table by giving the column name, optionally
-followed by the datatype in parentheses, followed by an equals sign and
-the arithmetic  expression to be used to compute the value.  The
-datatype is specified using the same syntax that is allowed for the
-value of the FITS TFORMn keyword (e.g., 'I', 'J', 'E', 'D', etc. for
-binary tables, and 'I8', F12.3', 'E20.12', etc.  for ASCII tables).  If
-the datatype is not specified then a default datatype will be chosen
-depending on the expression.
-
-\item
-Create a new header keyword by giving the keyword name, preceded by a
-pound sign '\#', followed by an equals sign and an arithmetic
-expression for the value of the keyword.  The expression may be a
-function of other header keyword values.  The comment string for the
-keyword may be specified in parentheses immediately following the
-keyword name.
-
-\item
-Overwrite the values in an existing column or keyword by giving the
-name followed by an equals sign and an arithmetic expression.
-
-\item
-Select a set of columns to be included in the filtered file by listing
-the column names separated with semi-colons.   Wild card characters may
-be used in the column names to match multiple columns.  Any other
-columns in the input table will not appear in the filtered file.
-
-\item
-Delete a column or keyword by listing the name preceded by a minus sign
-or an exclamation mark (!)
-
-\item
-Rename an existing column or keyword with the syntax 'NewName ==
-OldName'.
-
-\end{itemize}
-
-The column filtering specifier is enclosed in square brackets and
-begins with the string 'col'.   Multiple operations can be performed
-by separating them with semi-colons.  For  complex  or commonly used
-operations,  you can write the column filter to a text file, and then
-use it by giving the name of the text file, preceded by a '@'
-character.
-
-Some examples:
-
-\begin{verbatim}
-  [col PI=PHA * 1.1 + 0.2]      - creates new PI column from PHA values
-
-  [col rate = counts/exposure]  - creates or overwrites the rate column by
-                                  dividing the counts column by the
-                                  EXPOSURE keyword value.
-
-  [col TIME; X; Y]              - only the listed columns will appear
-                                  in the filtered file
-
-  [col Time;*raw]               - include the Time column and any other
-                                  columns whose name ends with 'raw'.
-
-  [col -TIME; Good == STATUS]   - deletes the TIME column and
-                                  renames the STATUS column to GOOD
-
-  [col @colfilt.txt]            - uses the filtering expression in
-                                  the colfilt.txt text file
-\end{verbatim}
-
-The original file is not changed by this filtering operation, and
-instead the modifications are made on a temporary copy of the input
-FITS file (usually in memory), which includes a copy of all the other
-HDUs in the input file.   The original input file is closed and the
-application program opens the filtered copy of the file.
-
-\subsubsection{Row Filtering}
-
-The row filter is used to select a subset of the rows from a table
-based on a boolean expression.  A temporary new FITS file is created on
-the fly (usually in memory) which contains only those rows for which
-the row filter expression evaluates to true (i.e., not equal to zero).
-The primary array and any other extensions in the input file are also
-copied to the temporary file.  The original FITS file is closed and the
-new temporary file is then opened by the application program.
-
-The row filter expression is enclosed in square brackets following the
-file name and extension name.  For example, {\tt
-'file.fits[events][GRADE==50]'}  selects only those rows in the EVENTS
-table where the GRADE column value is equal to 50).
-
-The row filtering  expression can be an arbitrarily  complex series of
-operations performed  on constants,  keyword values,  and column data
-taken from the specified FITS TABLE extension.  The expression 
-also can be written into a text file and then used by giving the
-filename preceded by a '@' character, as in
-{\tt '[@rowfilt.txt]'}.
-
-Keyword and column data  are referenced by   name.  Any  string of
-characters not surrounded by    quotes (ie, a constant  string)   or
-followed by   an open parentheses (ie,   a  function name)   will be
-initially interpreted   as a column  name and  its contents for the
-current row inserted into the expression.  If no such column exists,
-a keyword of that  name will be searched for  and its value used, if
-found.  To force the  name to be  interpreted as a keyword (in case
-there is both a column and keyword with the  same name), precede the
-keyword name with a single pound sign, '\#', as in {\tt \#NAXIS2}.  Due to
-the generalities of FITS column and  keyword names, if the column or
-keyword name  contains a space or a  character which might appear as
-an arithmetic  term then inclose  the  name in '\$'  characters as in
-{\tt \$MAX PHA\$} or {\tt \#\$MAX-PHA\$}.  The names are case insensitive.
-
-To access a table entry in a row other  than the current one, follow
-the  column's name  with  a row  offset  within  curly  braces.  For
-example, {\tt'PHA\{-3\}'} will evaluate to the value  of column PHA, 3 rows
-above  the  row currently  being processed.   One  cannot specify an
-absolute row number, only a relative offset.  Rows that fall outside
-the table will be treated as undefined, or NULLs.
-
-Boolean   operators can be  used in  the expression  in either their
-Fortran or C forms.  The following boolean operators are available:
-
-\begin{verbatim}
-    "equal"         .eq. .EQ. ==  "not equal"          .ne.  .NE.  !=
-    "less than"     .lt. .LT. <   "less than/equal"    .le.  .LE.  <= =<
-    "greater than"  .gt. .GT. >   "greater than/equal" .ge.  .GE.  >= =>
-    "or"            .or. .OR. ||  "and"                .and. .AND. &&
-    "negation"     .not. .NOT. !  "approx. equal(1e-7)"  ~
-\end{verbatim}
-
-Note  that the exclamation point,  '!', is a special UNIX character, so
-if it is used  on the command line rather than entered at a task
-prompt, it must be  preceded by a backslash to force the UNIX shell to
-ignore it.
-
-The expression may  also include arithmetic operators and functions.
-Trigonometric  functions use  radians,  not degrees.  The  following
-arithmetic  operators and  functions  can be  used in the expression
-(function names are case insensitive):
-
- 
-\begin{verbatim}
-    "addition"           +          "subtraction"          -
-    "multiplication"     *          "division"             /
-    "negation"           -          "exponentiation"       **   ^
-    "absolute value"     abs(x)     "cosine"               cos(x)
-    "sine"               sin(x)     "tangent"              tan(x)
-    "arc cosine"         arccos(x)  "arc sine"             arcsin(x)
-    "arc tangent"        arctan(x)  "arc tangent"          arctan2(x,y)
-    "exponential"        exp(x)     "square root"          sqrt(x)
-    "natural log"        log(x)     "common log"           log10(x)
-    "modulus"            i % j      "random # [0.0,1.0)"   random()
-    "minimum"            min(x,y)   "maximum"              max(x,y)
-    "if-then-else"       b?x:y
-\end{verbatim}
-
-
-The  following  type  casting  operators  are  available,  where the
-inclosing parentheses are required and taken  from  the  C  language
-usage. Also, the integer to real casts values to double precision:
-
-\begin{verbatim}
-                "real to integer"    (int) x     (INT) x
-                "integer to real"    (float) i   (FLOAT) i
-\end{verbatim}
-
-
-Several constants are built in  for  use  in  numerical
-expressions:
-
- 
-\begin{verbatim}
-        #pi              3.1415...      #e             2.7182...
-        #deg             #pi/180        #row           current row number
-        #null         undefined value   #snull         undefined string
-\end{verbatim}
-
-A  string constant must  be enclosed  in quotes  as in  'Crab'.  The
-"null" constants  are useful for conditionally  setting table values to
-a NULL, or undefined, value (For example,  {\tt "col1==-99 ? \#NULL :
-col1"}).
-
-There is also a function for testing if  two  values  are  close  to
-each  other,  i.e.,  if  they are "near" each other to within a user
-specified tolerance. The  arguments,  {\tt value\_1}  and  {\tt value\_2}  can  be
-integer  or  real  and  represent  the two values who's proximity is
-being tested to be within the specified tolerance, also  an  integer
-or real:
-
-\begin{verbatim}
-                    near(value_1, value_2, tolerance)
-\end{verbatim}
-
-When  a  NULL, or undefined, value is encountered in the FITS table,
-the expression will evaluate to NULL unless the undefined  value  is
-not   actually   required  for  evaluation,  e.g. "TRUE  .or.  NULL"
-evaluates to TRUE. The  following  two  functions  allow  some  NULL
-detection  and  handling:  
-
-\begin{verbatim}
-                   ISNULL(x)
-                   DEFNULL(x,y)
-\end{verbatim}
-
-The former returns a boolean value of TRUE if the  argument  x  is
-NULL.   The later  "defines"  a  value  to  be  substituted  for NULL
-values; it returns the value of x if x is not NULL, otherwise  it
-returns  the value of y.
-
-Bit  masks can be used to select out rows from bit columns ({\tt TFORMn =
-\#X}) in FITS files. To represent the mask,  binary,  octal,  and  hex
-formats are allowed:
- 
-\begin{verbatim}
-                 binary:   b0110xx1010000101xxxx0001
-                 octal:    o720x1 -> (b111010000xxx001)
-                 hex:      h0FxD  -> (b00001111xxxx1101)
-\end{verbatim}
-
-In  all  the  representations, an x or X is allowed in the mask as a
-wild card. Note that the x represents a  different  number  of  wild
-card  bits  in  each  representation.  All  representations are case
-insensitive.
-
-To construct the boolean expression using the mask  as  the  boolean
-equal  operator  described above on a bit table column. For example,
-if you had a 7 bit column named flags in a  FITS  table  and  wanted
-all  rows  having  the bit pattern 0010011, the selection expression
-would be:
-
- 
-\begin{verbatim}
-                            flags == b0010011
-    or
-                            flags .eq. b10011
-\end{verbatim}
-
-It is also possible to test if a range of bits is  less  than,  less
-than  equal,  greater  than  and  greater than equal to a particular
-boolean value:
-
- 
-\begin{verbatim}
-                            flags <= bxxx010xx
-                            flags .gt. bxxx100xx
-                            flags .le. b1xxxxxxx
-\end{verbatim}
-
-Notice the use of the x bit value to limit the range of  bits  being
-compared.
-
-It  is  not necessary to specify the leading (most significant) zero
-(0) bits in the mask, as shown in the second expression above.
-
-Bit wise AND, OR and NOT operations are  also  possible  on  two  or
-more  bit  fields  using  the  '\&'(AND),  '$|$'(OR),  and the '!'(NOT)
-operators. All of these operators result in a bit  field  which  can
-then be used with the equal operator. For example:
-
- 
-\begin{verbatim}
-                          (!flags) == b1101100
-                          (flags & b1000001) == bx000001
-\end{verbatim}
-
-Bit  fields can be appended as well using the '+' operator.  Strings
-can be concatenated this way, too.
-
-\subsubsection{Good Time Interval Filtering}
-
-    A common filtering method involves selecting rows which have a time
-    value which lies within what is called a Good Time Interval or GTI.
-    The time intervals are defined in a separate FITS table extension
-    which contains 2 columns giving the start and stop time of each
-    good interval.  The filtering operation accepts only those rows of
-    the input table which have an associated time which falls within
-    one of the time intervals defined in the GTI extension. A high
-    level function, gtifilter(a,b,c,d), is available which evaluates
-    each row of the input table  and returns TRUE  or FALSE depending
-    whether the row is inside or outside the  good time interval.  The
-    syntax is
- 
-\begin{verbatim}
-      gtifilter( [ "gtifile" [, expr [, "STARTCOL", "STOPCOL" ] ] ] )
-\end{verbatim}
-    where  each "[]" demarks optional parameters.  Note that  the quotes
-    around the gtifile and START/STOP column are required.  Either single
-    or double quote characters may be used.  The gtifile,
-    if specified,  can be blank  ("") which will  mean to use  the first
-    extension  with   the name "*GTI*"  in   the current  file,  a plain
-    extension  specifier (eg, "+2",  "[2]", or "[STDGTI]") which will be
-    used  to  select  an extension  in  the current  file, or  a regular
-    filename with or without an extension  specifier which in the latter
-    case  will mean to  use the first  extension  with an extension name
-    "*GTI*".  Expr can be   any arithmetic expression, including  simply
-    the time  column  name.  A  vector  time expression  will  produce a
-    vector boolean  result.  STARTCOL and  STOPCOL are the  names of the
-    START/STOP   columns in the    GTI extension.  If   one  of them  is
-    specified, they both  must be.
-
-    In  its  simplest form, no parameters need to be provided -- default
-    values will be used.  The expression {\tt "gtifilter()"} is equivalent to
- 
-\begin{verbatim}
-       gtifilter( "", TIME, "*START*", "*STOP*" )
-\end{verbatim}
-    This will search the current file for a GTI  extension,  filter  the
-    TIME  column in the current table, using START/STOP times taken from
-    columns in the GTI  extension  with  names  containing  the  strings
-    "START"  and "STOP".  The wildcards ('*') allow slight variations in
-    naming conventions  such  as  "TSTART"  or  "STARTTIME".   The  same
-    default  values  apply for unspecified parameters when the first one
-    or  two  parameters  are  specified.   The  function   automatically
-    searches   for   TIMEZERO/I/F   keywords  in  the  current  and  GTI
-    extensions, applying a relative time offset, if necessary.
-
-\subsubsection{Spatial Region Filtering}
-
-    Another common  filtering method selects rows based on whether the
-    spatial position associated with each row is located within a given
-    2-dimensional region.  The syntax for this high-level filter is
- 
-\begin{verbatim}
-       regfilter( "regfilename" [ , Xexpr, Yexpr [ , "wcs cols" ] ] )
-\end{verbatim}
-    where each "[ ]" demarks optional parameters. The region file name
-    is required and must be  enclosed in quotes.  The remaining
-    parameters are optional.  The region file is an ASCII text file
-    which contains a list of one or more geometric shapes (circle,
-    ellipse, box, etc.) which defines a region on the celestial sphere
-    or an area within a particular 2D image.  The region file is
-    typically generated using an image display program such as fv/POW
-    (distribute by the HEASARC), or ds9 (distributed by the Smithsonian
-    Astrophysical Observatory).  Users should refer to the documentation
-    provided with these programs for more details on the syntax used in
-    the region files.
-
-    In its simpliest form, (e.g., {\tt regfilter("region.reg")} ) the
-    coordinates in the default 'X' and 'Y' columns will be used to
-    determine if each row is inside or outside the area specified in
-    the region file.  Alternate position column names, or expressions,
-    may be entered if needed, as in
- 
-\begin{verbatim}
-        regfilter("region.reg", XPOS, YPOS)
-\end{verbatim}
-    Region filtering can be applied most unambiguously if the positions
-    in the region file and in the table to be filtered are both give in
-    terms of absolute celestial coordinate units.  In this case the
-    locations and sizes of the geometric shapes in the region file are
-    specified in angular units on the sky (e.g., positions given in
-    R.A. and Dec.  and sizes in arcseconds or arcminutes).  Similarly,
-    each row of the filtered table will have a celestial coordinate
-    associated with it.  This association is usually implemented using
-    a set of so-called 'World Coordinate System' (or WCS) FITS keywords
-    that define the coordinate transformation that must be applied to
-    the values in the 'X' and 'Y' columns to calculate the coordinate.
-
-    Alternatively, one can perform spatial filtering using unitless
-    'pixel' coordinates for the regions and row positions.  In this
-    case the user must be careful to ensure that the positions in the 2
-    files are self-consistent.  A typical problem is that the region
-    file may be generated using a binned image, but the unbinned
-    coordinates are given in the event table.  The ROSAT events files,
-    for example, have X and Y pixel coordinates that range from 1 -
-    15360.  These coordinates are typically binned by a factor of 32 to
-    produce a 480x480 pixel image.  If one then uses a region file
-    generated from this image (in image pixel units) to filter the
-    ROSAT events file, then the X and Y column values must be converted
-    to corresponding pixel units as in:
- 
-\begin{verbatim}
-        regfilter("rosat.reg", X/32.+.5, Y/32.+.5)
-\end{verbatim}
-    Note that this binning conversion is not necessary if the region
-    file is specified using celestial coordinate units instead of pixel
-    units because CFITSIO is then able to directly compare the
-    celestial coordinate of each row in the table with the celestial
-    coordinates in the region file without having to know anything
-    about how the image may have been binned.
-
-    The last "wcs cols" parameter should rarely be needed. If supplied,
-    this  string contains the names of the 2 columns (space or comma
-    separated) which have the associated WCS keywords. If not supplied,
-    the filter  will scan the X  and Y expressions for column names.
-    If only one is found in each  expression, those columns will be
-    used, otherwise an error will be returned.
-
-    These region shapes are supported (names are case insensitive):
- 
-\begin{verbatim}
-       Point         ( X1, Y1 )               <- One pixel square region
-       Line          ( X1, Y1, X2, Y2 )       <- One pixel wide region
-       Polygon       ( X1, Y1, X2, Y2, ... )  <- Rest are interiors with
-       Rectangle     ( X1, Y1, X2, Y2, A )       | boundaries considered
-       Box           ( Xc, Yc, Wdth, Hght, A )   V within the region
-       Diamond       ( Xc, Yc, Wdth, Hght, A )
-       Circle        ( Xc, Yc, R )
-       Annulus       ( Xc, Yc, Rin, Rout )
-       Ellipse       ( Xc, Yc, Rx, Ry, A )
-       Elliptannulus ( Xc, Yc, Rinx, Riny, Routx, Routy, Ain, Aout )
-       Sector        ( Xc, Yc, Amin, Amax )
-\end{verbatim}
-    where (Xc,Yc) is  the coordinate of  the shape's center; (X\#,Y\#) are
-    the coordinates  of the shape's edges;  Rxxx are the shapes' various
-    Radii or semimajor/minor  axes; and Axxx  are the angles of rotation
-    (or bounding angles for Sector) in degrees.  For rotated shapes, the
-    rotation angle  can  be left  off, indicating  no rotation.   Common
-    alternate  names for the regions  can also be  used: rotbox = box;
-    rotrectangle = rectangle;  (rot)rhombus = (rot)diamond;  and pie
-    = sector.  When a  shape's name is  preceded by a minus sign, '-',
-    the defined region  is instead the area  *outside* its boundary (ie,
-    the region is inverted).  All the shapes within a single region
-    file are OR'd together to create the region, and the order is
-    significant. The overall way of looking at region files is that if
-    the first region is an excluded region then a dummy included region
-    of the whole detector is inserted in the front. Then each region
-    specification as it is processed overrides any selections inside of
-    that region specified by previous regions. Another way of thinking
-    about this is that if a previous excluded region is completely
-    inside of a subsequent included region the excluded region is
-    ignored.
-
-    The positional coordinates may be given either in pixel units,
-    decimal degrees or hh:mm:ss.s, dd:mm:ss.s units.  The shape sizes
-    may be given in pixels, degrees, arcminutes, or arcseconds.  Look
-    at examples of region file produced by fv/POW or ds9 for further
-    details of the region file format.

-                                     less  than a half where the angles
-                                     are tabulated in degrees
-
-    [@rowFilter.txt]               - Extract rows using the expression
-                                     contained within the text file

-				     extension,  filter  the TIME
-				     column in the current table, using

-
-    [regfilter("pow.reg")]         - Extract rows which have a coordinate

-\subsection{Combined Filtering Examples}
-
-The previous sections described all the individual types of filters
-that may be applied to the input file.  In this section we show
-examples which combine several different filters at once.  These
-examples all use the {\tt fitscopy} program that is distributed with
-the CFITSIO code.  It simply copies the input file to the output file.
-
-\begin{verbatim}
-fitscopy rosat.fit out.fit
-\end{verbatim}
-
-This trivial example simply makes an identical copy of the input
-rosat.fit file without any filtering.
-
-\begin{verbatim}
-fitscopy 'rosat.fit[events][col Time;X;Y][#row < 1000]' out.fit
-\end{verbatim}
-
-The output file contains only the Time, X, and Y columns, and only
-the first 999 rows from the 'EVENTS' table extension of the input file.
-All the other HDUs in the input file are copied to the output file
-without any modification.
-
-\begin{verbatim}
-fitscopy 'rosat.fit[events][PI < 50][bin (Xdet,Ydet) = 16]' image.fit
-\end{verbatim}
-
-This creates an output image by binning the Xdet and Ydet columns of
-the events table with a pixel binning factor of 16.  Only the rows
-which have a PI energy less than 50 are used to construct this image.
-The output image file contains a primary array image without any
-extensions.
-
-\begin{verbatim}
-fitscopy 'rosat.fit[events][gtifilter() && regfilter("pow.reg")]' out.fit
-\end{verbatim}
-
-The filtering expression in this example uses the {\tt gtifilter}
-function to test whether the TIME column value in each row is within
-one of the Good Time Intervals defined in the GTI extension in the same
-input file, and also uses the {\tt regfilter} function to test if the
-position associated with each row (derived by default from the values
-in the X and Y columns of the events table) is located within the area
-defined in the {\tt pow.reg} text region file (which was previously
-created with the {\tt fv/POW} image display program).  Only the rows
-which satisfy both tests are copied to the output table.
-
-\begin{verbatim}
-fitscopy 'r.fit[evt][PI<50]' stdout | fitscopy stdin[evt][col X,Y] out.fit
-\end{verbatim}
-
-In this somewhat convoluted example, fitscopy is used to first select
-the rows from the evt extension which have PI less than 50 and write the
-resulting table out to the stdout stream.  This is piped to a 2nd
-instance of fitscopy (with the Unix `$|$' pipe command) which reads that
-filtered FITS file from the stdin stream and copies only the X and Y
-columns from the evt table to the output file.
-
-\begin{verbatim}
-fitscopy 'r.fit[evt][col RAD=sqrt((X-#XCEN)**2+(Y-#YCEN)**2)][rad<100]' out.fit
-\end{verbatim}
-
-This example first creates a new column called RAD which gives the
-distance between the X,Y coordinate of each event and the coordinate
-defined by the XCEN and YCEN keywords in the header.  Then, only those
-rows which have a distance less than 100 are copied to the output
-table.  In other words, only the events which are located within 100
-pixel units from the (XCEN, YCEN) coordinate are copied to the output
-table.
-
-\begin{verbatim}
-fitscopy 'ftp://heasarc.gsfc.nasa.gov/rosat.fit[events][bin (X,Y)=16]' img.fit
-\end{verbatim}
-
-This example bins the X and Y columns of the hypothetical ROSAT file 
-at the HEASARC ftp site to create the output image.
-
-\begin{verbatim}
-fitscopy 'raw.fit[i512,512][101:110,51:60]' image.fit
-\end{verbatim}
-
-This example converts the 512 x 512 pixel raw binary 16-bit integer
-image to a FITS file and copies a 10 x 10 pixel subimage from it to the
-output FITS image.
-
-\newpage
-\section{CFITSIO Error Status Codes}
-
-The following table lists all the error status codes used by CFITSIO.
-Programmers are encouraged to use the symbolic mnemonics (defined in
-the file fitsio.h) rather than the actual integer status values to
-improve the readability of their code.

- *  ALGORITHM
- *
- *      The "deflation" process uses several Huffman trees. The more
- *      common source values are represented by shorter bit sequences.
- *
- *      Each code tree is stored in a compressed form which is itself
- * a Huffman encoding of the lengths of all the code strings (in
- * ascending order by source values).  The actual code strings are
- * reconstructed from the lengths in the inflate process, as described
- * in the deflate specification.

- * winDumpExts.c --
- * Author:   Gordon Chaffee, Scott Stanton
- *
- * History:  The real functionality of this file was written by
- *           Matt Pietrek in 1993 in his pedump utility.  I've
- *           modified it to dump the externals in a bunch of object
- *           files to create a .def file.
- *
- * 10/12/95  Modified by Scott Stanton to support Relocatable Object Module
- *	     Format files for Borland C++ 4.5.
- *
- * Notes:    Visual C++ puts an underscore before each exported symbol.
- *           This file removes them.  I don't know if this is a problem
- *           this other compilers.  If _MSC_VER is defined,
- *           the underscore is removed.  If not, it isn't.  To get a
- *           full dump of an object file, use the -f option.  This can
- *           help determine the something that may be different with a
- *           compiler other than Visual C++.

-    The 'zlib' compression library provides in-memory compression and
-  decompression functions, including integrity checks of the uncompressed data.
-  This version of the library supports only one compression method (deflation)
-  but other algorithms will be added later and will have the same stream
-  interface.
-
-    Compression can be done in a single step if the buffers are large enough,
-  or can be done by repeated calls of the compression function.  In the latter
-  case, the application must provide more input and/or consume the output
-  (providing more output space) before each call.
-
-    The compressed data format used by default by the in-memory functions is
-  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
-  around a deflate stream, which is itself documented in RFC 1951.
-
-    The library also supports reading and writing files in gzip (.gz) format
-  with an interface similar to that of stdio using the functions that start
-  with "gz".  The gzip format is different from the zlib format.  gzip is a
-  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
-
-    This library can optionally read and write gzip streams in memory as well.
-
-    The zlib format was designed to be compact and fast for use in memory
-  and on communications channels.  The gzip format was designed for single-
-  file compression on file systems, has a larger header than zlib to maintain
-  directory information, and uses a different, slower check method than zlib.
-
-    The library does not install any signal handler.  The decoder checks
-  the consistency of the compressed data, so the library should never crash
-  even in case of corrupted input.

-ZEXTERN int ZEXPORT deflate OF((z_streamp strm, int flush));
-/*
-    deflate compresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full.  It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-    The detailed semantics are as follows.  deflate performs one or both of the
-  following actions:
-
-  - Compress more input starting at next_in and update next_in and avail_in
-    accordingly.  If not all input can be processed (because there is not
-    enough room in the output buffer), next_in and avail_in are updated and
-    processing will resume at this point for the next call of deflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly.  This action is forced if the parameter flush is non zero.
-    Forcing flush frequently degrades the compression ratio, so this parameter
-    should be set only when necessary (in interactive applications).  Some
-    output may be provided even if flush is not set.
-
-    Before the call of deflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming more
-  output, and updating avail_in or avail_out accordingly; avail_out should
-  never be zero before the call.  The application can consume the compressed
-  output when it wants, for example when the output buffer is full (avail_out
-  == 0), or after each call of deflate().  If deflate returns Z_OK and with
-  zero avail_out, it must be called again after making room in the output
-  buffer because there might be more output pending.
-
-    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
-  decide how much data to accumulate before producing output, in order to
-  maximize compression.
-
-    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
-  flushed to the output buffer and the output is aligned on a byte boundary, so
-  that the decompressor can get all input data available so far.  (In
-  particular avail_in is zero after the call if enough output space has been
-  provided before the call.) Flushing may degrade compression for some
-  compression algorithms and so it should be used only when necessary.  This
-  completes the current deflate block and follows it with an empty stored block
-  that is three bits plus filler bits to the next byte, followed by four bytes
-  (00 00 ff ff).
-
-    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
-  output buffer, but the output is not aligned to a byte boundary.  All of the
-  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
-  This completes the current deflate block and follows it with an empty fixed
-  codes block that is 10 bits long.  This assures that enough bytes are output
-  in order for the decompressor to finish the block before the empty fixed code
-  block.
-
-    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
-  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
-  seven bits of the current block are held to be written as the next byte after
-  the next deflate block is completed.  In this case, the decompressor may not
-  be provided enough bits at this point in order to complete decompression of
-  the data provided so far to the compressor.  It may need to wait for the next
-  block to be emitted.  This is for advanced applications that need to control
-  the emission of deflate blocks.
-
-    If flush is set to Z_FULL_FLUSH, all output is flushed as with
-  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
-  restart from this point if previous compressed data has been damaged or if
-  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
-  compression.
-
-    If deflate returns with avail_out == 0, this function must be called again
-  with the same value of the flush parameter and more output space (updated
-  avail_out), until the flush is complete (deflate returns with non-zero
-  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
-  avail_out is greater than six to avoid repeated flush markers due to
-  avail_out == 0 on return.
-
-    If the parameter flush is set to Z_FINISH, pending input is processed,
-  pending output is flushed and deflate returns with Z_STREAM_END if there was
-  enough output space; if deflate returns with Z_OK, this function must be
-  called again with Z_FINISH and more output space (updated avail_out) but no
-  more input data, until it returns with Z_STREAM_END or an error.  After
-  deflate has returned Z_STREAM_END, the only possible operations on the stream
-  are deflateReset or deflateEnd.
-
-    Z_FINISH can be used immediately after deflateInit if all the compression
-  is to be done in a single step.  In this case, avail_out must be at least the
-  value returned by deflateBound (see below).  If deflate does not return
-  Z_STREAM_END, then it must be called again as described above.
-
-    deflate() sets strm->adler to the adler32 checksum of all input read
-  so far (that is, total_in bytes).
-
-    deflate() may update strm->data_type if it can make a good guess about
-  the input data type (Z_BINARY or Z_TEXT).  In doubt, the data is considered
-  binary.  This field is only for information purposes and does not affect the
-  compression algorithm in any manner.
-
-    deflate() returns Z_OK if some progress has been made (more input
-  processed or more output produced), Z_STREAM_END if all input has been
-  consumed and all output has been produced (only when flush is set to
-  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
-  if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
-  (for example avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not
-  fatal, and deflate() can be called again with more input and more output
-  space to continue compressing.

-/*
-    inflate decompresses as much data as possible, and stops when the input
-  buffer becomes empty or the output buffer becomes full.  It may introduce
-  some output latency (reading input without producing any output) except when
-  forced to flush.
-
-  The detailed semantics are as follows.  inflate performs one or both of the
-  following actions:
-
-  - Decompress more input starting at next_in and update next_in and avail_in
-    accordingly.  If not all input can be processed (because there is not
-    enough room in the output buffer), next_in is updated and processing will
-    resume at this point for the next call of inflate().
-
-  - Provide more output starting at next_out and update next_out and avail_out
-    accordingly.  inflate() provides as much output as possible, until there is
-    no more input data or no more space in the output buffer (see below about
-    the flush parameter).
-
-    Before the call of inflate(), the application should ensure that at least
-  one of the actions is possible, by providing more input and/or consuming more
-  output, and updating the next_* and avail_* values accordingly.  The
-  application can consume the uncompressed output when it wants, for example
-  when the output buffer is full (avail_out == 0), or after each call of
-  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
-  called again after making room in the output buffer because there might be
-  more output pending.
-
-    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
-  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
-  output as possible to the output buffer.  Z_BLOCK requests that inflate()
-  stop if and when it gets to the next deflate block boundary.  When decoding
-  the zlib or gzip format, this will cause inflate() to return immediately
-  after the header and before the first block.  When doing a raw inflate,
-  inflate() will go ahead and process the first block, and will return when it
-  gets to the end of that block, or when it runs out of data.
-
-    The Z_BLOCK option assists in appending to or combining deflate streams.
-  Also to assist in this, on return inflate() will set strm->data_type to the
-  number of unused bits in the last byte taken from strm->next_in, plus 64 if
-  inflate() is currently decoding the last block in the deflate stream, plus
-  128 if inflate() returned immediately after decoding an end-of-block code or
-  decoding the complete header up to just before the first byte of the deflate
-  stream.  The end-of-block will not be indicated until all of the uncompressed
-  data from that block has been written to strm->next_out.  The number of
-  unused bits may in general be greater than seven, except when bit 7 of
-  data_type is set, in which case the number of unused bits will be less than
-  eight.  data_type is set as noted here every time inflate() returns for all
-  flush options, and so can be used to determine the amount of currently
-  consumed input in bits.
-
-    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
-  end of each deflate block header is reached, before any actual data in that
-  block is decoded.  This allows the caller to determine the length of the
-  deflate block header for later use in random access within a deflate block.
-  256 is added to the value of strm->data_type when inflate() returns
-  immediately after reaching the end of the deflate block header.
-
-    inflate() should normally be called until it returns Z_STREAM_END or an
-  error.  However if all decompression is to be performed in a single step (a
-  single call of inflate), the parameter flush should be set to Z_FINISH.  In
-  this case all pending input is processed and all pending output is flushed;
-  avail_out must be large enough to hold all the uncompressed data.  (The size
-  of the uncompressed data may have been saved by the compressor for this
-  purpose.) The next operation on this stream must be inflateEnd to deallocate
-  the decompression state.  The use of Z_FINISH is never required, but can be
-  used to inform inflate that a faster approach may be used for the single
-  inflate() call.
-
-     In this implementation, inflate() always flushes as much output as
-  possible to the output buffer, and always uses the faster approach on the
-  first call.  So the only effect of the flush parameter in this implementation
-  is on the return value of inflate(), as noted below, or when it returns early
-  because Z_BLOCK or Z_TREES is used.
-
-     If a preset dictionary is needed after this call (see inflateSetDictionary
-  below), inflate sets strm->adler to the adler32 checksum of the dictionary
-  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
-  strm->adler to the adler32 checksum of all output produced so far (that is,
-  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
-  below.  At the end of the stream, inflate() checks that its computed adler32
-  checksum is equal to that saved by the compressor and returns Z_STREAM_END
-  only if the checksum is correct.
-
-    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
-  deflate data.  The header type is detected automatically, if requested when
-  initializing with inflateInit2().  Any information contained in the gzip
-  header is not retained, so applications that need that information should
-  instead use raw inflate, see inflateInit2() below, or inflateBack() and
-  perform their own processing of the gzip header and trailer.
-
-    inflate() returns Z_OK if some progress has been made (more input processed
-  or more output produced), Z_STREAM_END if the end of the compressed data has
-  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
-  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
-  corrupted (input stream not conforming to the zlib format or incorrect check
-  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
-  next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
-  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
-  output buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
-  inflate() can be called again with more input and more output space to
-  continue decompressing.  If Z_DATA_ERROR is returned, the application may
-  then call inflateSync() to look for a good compression block if a partial
-  recovery of the data is desired.

-
-     This is another version of deflateInit with more compression options.  The
-   fields next_in, zalloc, zfree and opaque must be initialized before by the
-   caller.
-
-     The method parameter is the compression method.  It must be Z_DEFLATED in
-   this version of the library.
-
-     The windowBits parameter is the base two logarithm of the window size
-   (the size of the history buffer).  It should be in the range 8..15 for this
-   version of the library.  Larger values of this parameter result in better
-   compression at the expense of memory usage.  The default value is 15 if
-   deflateInit is used instead.
-
-     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
-   determines the window size.  deflate() will then generate raw deflate data
-   with no zlib header or trailer, and will not compute an adler32 check value.
-
-     windowBits can also be greater than 15 for optional gzip encoding.  Add
-   16 to windowBits to write a simple gzip header and trailer around the
-   compressed data instead of a zlib wrapper.  The gzip header will have no
-   file name, no extra data, no comment, no modification time (set to zero), no
-   header crc, and the operating system will be set to 255 (unknown).  If a
-   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
-
-     The memLevel parameter specifies how much memory should be allocated
-   for the internal compression state.  memLevel=1 uses minimum memory but is
-   slow and reduces compression ratio; memLevel=9 uses maximum memory for
-   optimal speed.  The default value is 8.  See zconf.h for total memory usage
-   as a function of windowBits and memLevel.
-
-     The strategy parameter is used to tune the compression algorithm.  Use the
-   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
-   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
-   string match), or Z_RLE to limit match distances to one (run-length
-   encoding).  Filtered data consists mostly of small values with a somewhat
-   random distribution.  In this case, the compression algorithm is tuned to
-   compress them better.  The effect of Z_FILTERED is to force more Huffman
-   coding and less string matching; it is somewhat intermediate between
-   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
-   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
-   strategy parameter only affects the compression ratio but not the
-   correctness of the compressed output even if it is not set appropriately.
-   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
-   decoder for special applications.
-
-     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
-   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
-   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
-   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is
-   set to null if there is no error message.  deflateInit2 does not perform any
-   compression: this will be done by deflate().

-   of deflate.  The compressor and decompressor must use exactly the same
-   dictionary (see inflateSetDictionary).
-
-     The dictionary should consist of strings (byte sequences) that are likely
-   to be encountered later in the data to be compressed, with the most commonly
-   used strings preferably put towards the end of the dictionary.  Using a
-   dictionary is most useful when the data to be compressed is short and can be
-   predicted with good accuracy; the data can then be compressed better than
-   with the default empty dictionary.
-
-     Depending on the size of the compression data structures selected by
-   deflateInit or deflateInit2, a part of the dictionary may in effect be
-   discarded, for example if the dictionary is larger than the window size
-   provided in deflateInit or deflateInit2.  Thus the strings most likely to be
-   useful should be put at the end of the dictionary, not at the front.  In
-   addition, the current implementation of deflate will use at most the window
-   size minus 262 bytes of the provided dictionary.
-
-     Upon return of this function, strm->adler is set to the adler32 value
-   of the dictionary; the decompressor may later use this value to determine
-   which dictionary has been used by the compressor.  (The adler32 value
-   applies to the whole dictionary even if only a subset of the dictionary is
-   actually used by the compressor.) If a raw deflate was requested, then the

-   instead.  windowBits must be greater than or equal to the windowBits value
-   provided to deflateInit2() while compressing, or it must be equal to 15 if
-   deflateInit2() was not used.  If a compressed stream with a larger window
-   size is given as input, inflate() will return with the error code

-     windowBits can also be zero to request that inflate use the window size in

-   looking for any check values for comparison at the end of the stream.  This
-   is for use with other formats that use the deflate compressed data format
-   such as zip.  Those formats provide their own check values.  If a custom

-   recommended that a check value such as an adler32 or a crc32 be applied to
-   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
-   most applications, the zlib format should be used as is.  Note that comments
-   above on the use in deflateInit2() applies to the magnitude of windowBits.
-

-     inflateBack() does a raw inflate with a single call using a call-back
-   interface for input and output.  This is more efficient than inflate() for
-   file i/o applications in that it avoids copying between the output and the
-   sliding window by simply making the window itself the output buffer.  This
-   function trusts the application to not change the output buffer passed by
-   the output function, at least until inflateBack() returns.
-
-     inflateBackInit() must be called first to allocate the internal state
-   and to initialize the state with the user-provided window buffer.
-   inflateBack() may then be used multiple times to inflate a complete, raw
-   deflate stream with each call.  inflateBackEnd() is then called to free the
-   allocated state.
-
-     A raw deflate stream is one with no zlib or gzip header or trailer.
-   This routine would normally be used in a utility that reads zip or gzip
-   files and writes out uncompressed files.  The utility would decode the
-   header and process the trailer on its own, hence this routine expects only
-   the raw deflate stream to decompress.  This is different from the normal
-   behavior of inflate(), which expects either a zlib or gzip header and
-   trailer around the deflate stream.
-
-     inflateBack() uses two subroutines supplied by the caller that are then
-   called by inflateBack() for input and output.  inflateBack() calls those
-   routines until it reads a complete deflate stream and writes out all of the
-   uncompressed data, or until it encounters an error.  The function's
-   parameters and return types are defined above in the in_func and out_func
-   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
-   number of bytes of provided input, and a pointer to that input in buf.  If
-   there is no input available, in() must return zero--buf is ignored in that
-   case--and inflateBack() will return a buffer error.  inflateBack() will call
-   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
-   should return zero on success, or non-zero on failure.  If out() returns
-   non-zero, inflateBack() will return with an error.  Neither in() nor out()
-   are permitted to change the contents of the window provided to
-   inflateBackInit(), which is also the buffer that out() uses to write from.
-   The length written by out() will be at most the window size.  Any non-zero
-   amount of input may be provided by in().
-
-     For convenience, inflateBack() can be provided input on the first call by
-   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
-   in() will be called.  Therefore strm->next_in must be initialized before
-   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
-   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
-   must also be initialized, and then if strm->avail_in is not zero, input will
-   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
-
-     The in_desc and out_desc parameters of inflateBack() is passed as the
-   first parameter of in() and out() respectively when they are called.  These
-   descriptors can be optionally used to pass any information that the caller-
-   supplied in() and out() functions need to do their job.
-
-     On return, inflateBack() will set strm->next_in and strm->avail_in to
-   pass back any unused input that was provided by the last in() call.  The
-   return values of inflateBack() can be Z_STREAM_END on success, Z_BUF_ERROR
-   if in() or out() returned an error, Z_DATA_ERROR if there was a format error
-   in the deflate stream (in which case strm->msg is set to indicate the nature
-   of the error), or Z_STREAM_ERROR if the stream was not properly initialized.
-   In the case of Z_BUF_ERROR, an input or output error can be distinguished
-   using strm->next_in which will be Z_NULL only if in() returned an error.  If
-   strm->next_in is not Z_NULL, then the Z_BUF_ERROR was due to out() returning
-   non-zero.  (in() will always be called before out(), so strm->next_in is
-   assured to be defined if out() returns non-zero.) Note that inflateBack()

-CeCILL FREE SOFTWARE LICENSE AGREEMENT
-
-
-    Notice
-
-This Agreement is a Free Software license agreement that is the result
-of discussions between its authors in order to ensure compliance with
-the two main principles guiding its drafting:
-
-    * firstly, compliance with the principles governing the distribution
-      of Free Software: access to source code, broad rights granted to
-      users,
-    * secondly, the election of a governing law, French law, with which
-      it is conformant, both as regards the law of torts and
-      intellectual property law, and the protection that it offers to
-      both authors and holders of the economic rights over software.
-
-The authors of the CeCILL (for Ce[a] C[nrs] I[nria] L[ogiciel] L[ibre])
-license are:
-
-Commissariat à l'Energie Atomique - CEA, a public scientific, technical
-and industrial research establishment, having its principal place of
-business at 25 rue Leblanc, immeuble Le Ponant D, 75015 Paris, France.
-
-Centre National de la Recherche Scientifique - CNRS, a public scientific
-and technological establishment, having its principal place of business
-at 3 rue Michel-Ange, 75794 Paris cedex 16, France.
-
-Institut National de Recherche en Informatique et en Automatique -
-INRIA, a public scientific and technological establishment, having its
-principal place of business at Domaine de Voluceau, Rocquencourt, BP
-105, 78153 Le Chesnay cedex, France.
-
-
-    Preamble
-
-The purpose of this Free Software license agreement is to grant users
-the right to modify and redistribute the software governed by this
-license within the framework of an open source distribution model.
-
-The exercising of these rights is conditional upon certain obligations
-for users so as to preserve this status for all subsequent redistributions.
-
-In consideration of access to the source code and the rights to copy,
-modify and redistribute granted by the license, users are provided only
-with a limited warranty and the software's author, the holder of the
-economic rights, and the successive licensors only have limited liability.
-
-In this respect, the risks associated with loading, using, modifying
-and/or developing or reproducing the software by the user are brought to
-the user's attention, given its Free Software status, which may make it
-complicated to use, with the result that its use is reserved for
-developers and experienced professionals having in-depth computer
-knowledge. Users are therefore encouraged to load and test the
-suitability of the software as regards their requirements in conditions
-enabling the security of their systems and/or data to be ensured and,
-more generally, to use and operate it in the same conditions of
-security. This Agreement may be freely reproduced and published,
-provided it is not altered, and that no provisions are either added or
-removed herefrom.
-
-This Agreement may apply to any or all software for which the holder of
-the economic rights decides to submit the use thereof to its provisions.

-loss of profits, operating loss, loss of customers or orders,
-opportunity cost, any disturbance to business activities) or any or all
-legal proceedings instituted against the Licensee by a third party,
-shall constitute consequential loss and shall not provide entitlement to
-any or all compensation from the Licensor.
-
-
-    Article 9 - WARRANTY
-
-9.1 The Licensee acknowledges that the scientific and technical
-state-of-the-art when the Software was distributed did not enable all
-possible uses to be tested and verified, nor for the presence of
-possible defects to be detected. In this respect, the Licensee's
-attention has been drawn to the risks associated with loading, using,
-modifying and/or developing and reproducing the Software which are
-reserved for experienced users.
-
-The Licensee shall be responsible for verifying, by any or all means,
-the suitability of the product for its requirements, its good working
-order, and for ensuring that it shall not cause damage to either persons
-or properties.
-
-9.2 The Licensor hereby represents, in good faith, that it is entitled
-to grant all the rights over the Software (including in particular the
-rights set forth in Article 5).
-
-9.3 The Licensee acknowledges that the Software is supplied "as is" by
-the Licensor without any other express or tacit warranty, other than
-that provided for in Article 9.2 and, in particular, without any warranty 
-as to its commercial value, its secured, safe, innovative or relevant
-nature.
-
-Specifically, the Licensor does not warrant that the Software is free
-from any error, that it will operate without interruption, that it will
-be compatible with the Licensee's own equipment and software
-configuration, nor that it will meet the Licensee's requirements.
-
-9.4 The Licensor does not either expressly or tacitly warrant that the
-Software does not infringe any third party intellectual property right
-relating to a patent, software or any other property right. Therefore,
-the Licensor disclaims any and all liability towards the Licensee
-arising out of any or all proceedings for infringement that may be
-instituted in respect of the use, modification and redistribution of the
-Software. Nevertheless, should such proceedings be instituted against
-the Licensee, the Licensor shall provide it with technical and legal
-assistance for its defense. Such technical and legal assistance shall be
-decided on a case-by-case basis between the relevant Licensor and the
-Licensee pursuant to a memorandum of understanding. The Licensor
-disclaims any and all liability as regards the Licensee's use of the
-name of the Software. No warranty is given as regards the existence of
-prior rights over the name of the Software or as regards the existence
-of a trademark.
-
-
-    Article 10 - TERMINATION
-
-10.1 In the event of a breach by the Licensee of its obligations
-hereunder, the Licensor may automatically terminate this Agreement
-thirty (30) days after notice has been sent to the Licensee and has
-remained ineffective.
-
-10.2 A Licensee whose Agreement is terminated shall no longer be
-authorized to use, modify or distribute the Software. However, any
-licenses that it may have granted prior to termination of the Agreement
-shall remain valid subject to their having been granted in compliance
-with the terms and conditions hereof.
-
-
-    Article 11 - MISCELLANEOUS
-
-
-      11.1 EXCUSABLE EVENTS
-
-Neither Party shall be liable for any or all delay, or failure to
-perform the Agreement, that may be attributable to an event of force
-majeure, an act of God or an outside cause, such as defective
-functioning or interruptions of the electricity or telecommunications
-networks, network paralysis following a virus attack, intervention by
-government authorities, natural disasters, water damage, earthquakes,
-fire, explosions, strikes and labor unrest, war, etc.
-
-11.2 Any failure by either Party, on one or more occasions, to invoke
-one or more of the provisions hereof, shall under no circumstances be
-interpreted as being a waiver by the interested Party of its right to
-invoke said provision(s) subsequently.
-
-11.3 The Agreement cancels and replaces any or all previous agreements,
-whether written or oral, between the Parties and having the same
-purpose, and constitutes the entirety of the agreement between said
-Parties concerning said purpose. No supplement or modification to the
-terms and conditions hereof shall be effective as between the Parties
-unless it is made in writing and signed by their duly authorized
-representatives.
-
-11.4 In the event that one or more of the provisions hereof were to
-conflict with a current or future applicable act or legislative text,
-said act or legislative text shall prevail, and the Parties shall make
-the necessary amendments so as to comply with said act or legislative
-text. All other provisions shall remain effective. Similarly, invalidity
-of a provision of the Agreement, for any reason whatsoever, shall not
-cause the Agreement as a whole to be invalid.
-

-
-The Agreement is drafted in both French and English and both versions
-are deemed authentic.
-
-
-    Article 12 - NEW VERSIONS OF THE AGREEMENT

-Agreement, each with a separate number. These subsequent versions may
-address new issues encountered by Free Software.
-
-12.3 Any Software distributed under a given version of the Agreement may
-only be subsequently distributed under the same version of the Agreement
-or a subsequent version, subject to the provisions of Article 5.3.4.
-
-
-    Article 13 - GOVERNING LAW AND JURISDICTION
-
-13.1 The Agreement is governed by French law. The Parties agree to
-endeavor to seek an amicable solution to any disagreements or disputes
-that may arise during the performance of the Agreement.

-/* ------------------------ DRIVER ROUTINE --------------------------- */
-/* The following is an example of a driver routine you might use. */
-/* Basically, the driver routine needs to call TFset_parameters() to
-set all the scalar parameters, and then call TFfit_onek() for each 
-wavenumber k you desire. */
-
-/* While the routines use Mpc^-1 units internally, this driver has been
-written to take an array of wavenumbers in units of h Mpc^-1.  On the
-other hand, if you want to use Mpc^-1 externally, you can do this by
-altering the variables you pass to the driver:  
-	omega0 -> omega0*hubble*hubble, hubble -> 1.0 		*/
-
-/* INPUT: omega0 -- the matter density (baryons+CDM) in units of critical 
-	  f_baryon -- the ratio of baryon density to matter density 
-	  hubble -- the Hubble constant, in units of 100 km/s/Mpc
-	  Tcmb -- the CMB temperature in Kelvin. T<=0 uses the COBE value 2.728.
-	  numk -- the length of the following zero-offset array
-	  k[] -- the array of wavevectors k[0..numk-1]  */
-
-/* INPUT/OUTPUT: There are three output arrays of transfer functions. 
-All are zero-offset and, if used, must have storage [0..numk-1] declared
-in the calling program.  However, if you substitute the NULL pointer for
-one or more of the arrays, then that particular transfer function won't
-be outputted. The transfer functions are:
-
-	tf_full[] -- The full fitting formula, eq. (16), for the matter
-			transfer function. 
-	tf_baryon[] -- The baryonic piece of the full fitting formula, eq. 21.
-	tf_cdm[] -- The CDM piece of the full fitting formula, eq. 17. */
-
-/* Again, you can set these pointers to NULL in the function call if
-you don't want a particular output. */
-
-/* Various intermediate scalar quantities are stored in global variables, 
-so that you might more easily access them.  However, this also means that
-you would be better off not simply #include'ing this file in your programs,
-but rather compiling it separately, calling only the driver, and using
-extern declarations to access the intermediate quantities. */

-/* There are two routines here.  TFset_parameters() sets all the scalar
-parameters, while TFfit_onek() calculates the transfer function for a

-call to TFset_parameters() */
