NAME

       astscript-psf-stamp - Make normalized stamp of star with background objects masked

SYNOPSIS

       astscript-psf-stamp [OPTION] FITS-files

DESCRIPTION

       This script is part of GNU Astronomy Utilities 0.19.

       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
              HDU/extension of all input FITS files.

       -c, --center=FLT,FLT
              Center coordinates of the object.

       -W, --widthinpix=INT,INT Width of the stamp in pixels.

       -T, --snthresh=FLT

              for computing the normalization value.

       -S, --segment=STR
              Output of Segment (with OBJECTS and CLUMPS).

       -N, --normop=STR
              Operator for computing the normalization value (mean, sigclip-mean, etc.).

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

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

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

       -d, --nocentering
              Don't warp the center coord to central pixel.

              Output:

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

       -t, --tmpdir
              Directory to keep temporary files.

       -k, --keeptmp
              Keep temporal/auxiliar files.

              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.
