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 0.23.

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
