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

astscript-psf-stamp [OPTION] FITS-files

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.

$ info astscript-psf-stamp
$ 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

Input:
HDU/extension of all input FITS files.
Coordinates mode ('wcs' or 'img').
Center coordinates of the object.

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

Mask pixels below this S/N (only when '--segment' is given).
for computing the normalization value.
Output of Segment (with OBJECTS and CLUMPS).
Operator for computing the normalization value (mean, sigclip-mean, etc.).
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.

Don't warp the center coord to central pixel.
Output:
Output table with the radial profile.
Directory to keep temporary files.
Keep temporal/auxiliar files.
Operating mode:
-?, --help
Print this help list.
BibTeX citation for this program.
Don't print any extra information in stdout.
Print program version.
