NAME
astscript-psf-unite - Unite the outer and inner regions of the PSF
SYNOPSIS
astscript-psf-unite [OPTION] FITS-files
DESCRIPTION
This script is part of GNU Astronomy Utilities 0.22.
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 compre‐
hensive 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
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 de‐
velopers. For more information, please run:
$ info help-gnuastro
astscript-psf-unite options:
Input:
-h, --hdu=STR
HDU/extension of all input FITS files.
-i, --inner=STR
Inner PSF FITS image.
-I, --innerhdu=STR
HDU/extension of the inner PSF image.
-r, --radius=FLT
Radius at which the junction is done (in pixels).
-s, --scale=FLT
Factor by which the inner PSF is multiplied.
-Q, --axis-ratio=FLT
Axis ratio for ellipse maskprofile (A/B).
-p, --position-angle=FLT Position angle for ellipse mask profile.
Output:
-o, --output
Output table with the radial profile.
-t, --tmpdir
Directory to keep temporary files.
-k, --keeptmp
Keep temporal/auxiliar files.
Operating mode:
-?, --help
Print this help list.
--cite BibTeX citation for this program.
-q, --quiet
Don't print any extra information in stdout.
-V, --version
Print program version.
Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short op‐
tions.
