#plot the angular mask described by a polygon file in .list format
#using the matlab mapping toolbox
#
#optional 3rd-6th arguments give the RA and Dec range to plot the mask
#if no range is given, the full sky will be plotted
#To plot range that includes RA=0, use a negative number for the "low"
#end, e.g. for a 10 degree strip covering RA=355 degrees to RA=5 degrees,
#use a range of -5 5.
#Entering in "0 0 0 0" for the range will also give the default full sky behavior,
#which can be used if you also wish to, e.g., enter a title. 
#
#optional 7th argument gives a title for the graph
#optional 8th argument turns on drawing black outlines around each polygon
#
#if specifying the full path to a file (rather than just running in the directory 
#containing the file you want to plot), put the path in double-quotes as shown below.
#
#USAGE: graphmask.sh <infile> <outfile> [<ramin> <ramax> <decmin> <decmax>] [<title>] [<outlines>]
