NAME

astscript-radial-profile - Create a radial profile of an object in an image

SYNOPSIS

astscript-radial-profile [OPTION] FITS-files

DESCRIPTION

This script is part of GNU Astronomy Utilities 0.19.

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
