       Written/developed by Mohammad Akhlaghi, Raul Infante-Sainz and Sepideh Eskandarlou.

       Given  a  set  of  dithering  positions  ('positions-cat.fits'  in  the  example  above),  and  an  image
       ('image.fits'  which can be from any part of the sky, only its distortion and orientation are important),
       build the exposure map of the output stack after applying that dither  (where  each  pixel  contains  the
       number  of  exposures  that were used in it). The field of the final stack can be set with the '--center'
       and '--width' options.

   astscript-pointing-simulateoptions:
              Input:

       -h, --hdu=STR/INT
              HDU name or number of the positions catalog.

       -i, --img=STR
              Name of reference image.

       -H, --imghdu=STR/INT
              HDU name or number of the input image.

       -r, --racol=STR/INT
              Name/number of column containing RA.

       -d, --deccol=STR/INT
              Name/number of column containing Declination.

       --mksrc=STR
              Makefile (for developers when debugging).

              Hooks:

       --hook-warp-before='COMMAND' Before warping each exposure;
              Input: ''. Output: ''.

       --hook-warp-after='COMMAND' After warping each exposure;
              Input: ''. Output: ''.

              Output:

       -o, --output=STR
              Name of finally stacked image.

       -C, --center=FLT,FLT
              Center of output stack (in RA,Dec).

       -w, --width=FLT,FLT
              Width of output stack (in WCS).

       --ctype=STR,STR
              Projection of output (CTYPEi in WCS).

       --widthinpix
              Interpret '--width' values in pixels.

       --stack-operator="STR" Arithmetic operator to use for stacking.

       -t, --tmpdir=STR
              Directory to keep temporary files.

       -k, --keeptmp
              Keep temporal/auxiliar files.

              Operating mode:

       -?, --help
              Print this help.

       -N, --numthreads=INT
              Number of threads; maximum if not given.

       --cite BibTeX citation for this program.

       -q, --quiet
              Don't print any extra information in stdout.

       -V, --version
              Print program version.

       Mandatory or optional arguments to long options are also mandatory  or  optional  for  any  corresponfing
       short options.
