.SH NAME
astscript-radial-profile \- Create a radial profile of an object in an image
.SH SYNOPSIS
.B astscript-radial-profile
[\fI\,OPTION\/\fR] \fI\,FITS-files\/\fR
.SH DESCRIPTION
This script is part of GNU Astronomy Utilities 0.24.
.PP
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.
