NAME
astscript-psf-subtract - Subtract a given PSF model from the image
SYNOPSIS
astscript-psf-subtract [OPTION] FITS-files
DESCRIPTION
This script is part of GNU Astronomy Utilities 0.22.
This script will place the given PSF image into a certain central position with the image and subtract it.
For more information, please run any of the following commands. In particular the first contains a very compre‐
hensive explanation of this script's invocation: expected input(s), output(s), and a full description of all the
options.
Inputs/Outputs and options:
$ info astscript-psf-subtract
Full Gnuastro manual/book:
$ info gnuastro
If you couldn't find your answer in the manual, you can get direct help from experienced Gnuastro users and de‐
velopers. For more information, please run:
$ info help-gnuastro
astscript-psf-subtract options:
Input:
-h, --hdu=STR
HDU/extension of all input FITS files.
-p, --psf=STR
PSF FITS image.
-P, --psfhdu=STR
HDU/extension of the PSF image.
-O, --mode=STR
Coordinates mode ('wcs' or 'img').
-c, --center=FLT,FLT
Center coordinates of the object.
-s, --scale=FLT
Factor by which the PSF is multiplied.
Output:
-o, --output
Output table with the radial profile.
-t, --tmpdir
Directory to keep temporary files.
-k, --keeptmp
Keep temporal/auxiliar files.
-m, --modelonly
Give the model as output (don't subtract it).
Operating mode:
-?, --help
Print this help list.
--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 corresponding short op‐
tions.
