NAME

       astscript-psf-stamp - Make normalized stamp with other sources masked

SYNOPSIS

       astscript-psf-stamp [OPTION] FITS-files

DESCRIPTION

       This script is part of GNU Astronomy Utilities 0.22.

       This  script  will  consider  a  center  position to make a normalized stamp. It is intendeed to generate
       several stamps and combine them to obtain a PSF.

       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
       description of all the options.

       Inputs/Outputs and options:
              $ info astscript-psf-stamp

       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 developers. For more information, please run:

              $ info help-gnuastro

   astscript-psf-stamp options:
              Input:

       -h, --hdu=STR

       -Q, --axis-ratio=FLT
              Axis ratio for ellipse maskprofile (A/B).

       -p, --position-angle=FLT Position angle for ellipse mask profile.

       -s, --sigmaclip=FLT,FLT Sigma-clip multiple and tolerance.

       -d, --nocentering

              Output:

       -o, --output
              Output table with the radial profile.

       -t, --tmpdir

              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

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