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 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-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 optional for any corresponfing short options.
