NAME
       astscript-pointing-simulate  -  Simulate	the exposure map of a pointing
       pattern

SYNOPSIS
       astscript-pointing-simulate    positions-cat.fits    --center=1.23,4.56
       --width=2,2 --img=image.fits [OPTIONS]

DESCRIPTION
       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  ex-
       posure  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'  op-
       tions.

   astscript-pointing-simulate options:
	      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
