ASTSCRIPT-PSF-UNITE(1)

NAME
astscript-psf-unite - Unite the outer and inner regions of the PSF into one

SYNOPSIS
astscript-psf-unite [OPTION] FITS-files

DESCRIPTION
This script is part of GNU Astronomy Utilities 0.18.

This script will consider two different PSF images to join them into a single one. It is intendeed to generate a single PSF by combining different PSF regions (inner and outer).

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-unite
