NAME
       astscript-psf-scale-factor - Find factor to scale PSF to a given star


SYNOPSIS
       astscript-psf-scale-factor [OPTION] FITS-files


DESCRIPTION
       This script is part of GNU Astronomy Utilities 0.23.

       This  script  will  consider  a  center  position and then compute the factor by which it is necessary to
       multiply the specified PSF image in order to match it with the  object  at  the  center  (within  a  ring
       radii).  The  main  idea  is  to have the necessary factor that will be used to allocate the PSF with the
       proper flux value for constructing the scattered light field.

       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-scale-factor

       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:

              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 options.
