This script is part of GNU Astronomy Utilities 0.23.
This script will consider the input image for constructing the radial profile around a given center with
elliptical apertures.
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-radial-profile
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
