astscript-psf-stamp1
Make normalized stamp with other sources masked
Usage
astscript-psf-stamp [OPTION]
FITS-files
Overview
This script is part of GNU Astronomy Utilities 0.23.
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.
