To make a discrete approximation to a mask using approximate
|
||
|
|
HEALPix pixels, do
|
||
|
|
healpixrast.sh <polygon_infile> <Nside> <polygon_outfile>
|
||
|
|
where Nside is the desired HEALPix resolution.
|
||
|
|
|
||
|
|
To generate an output file in FITS format that can later be read
|
||
|
|
by the HEALPix software, do
|
||
|
|
healpixrast2fits.sh <polygon_infile> <Nside> <fits_outfile>
|
||
|
|
|
||
|
|
|
||
|
|
Polygon files of the approximate HEALPix pixels are located in
|
||
|
|
the healpix_polys directory for resolutions up to Nside=32.
|
||
|
|
Files for higher resolutions are available at
