NAME¶
astscript-psf-stamp - Make normalized stamp with other sources masked
SYNOPSIS¶
astscript-psf-stamp [OPTION] FITS-files
DESCRIPTION¶
This script is part of GNU Astronomy Utilities 0.22.
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
