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 0.23.

       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
       comprehensive  explanation  of  this  script's  invocation:  expected  input(s),  output(s),  and  a full

   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

       -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.
