ASTSCRIPT-PSF-STAMP

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.

-O, --mode=STR

-c, --center=FLT,FLT

Center coordinates of the object.

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

-T, --snthresh=FLT
