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 0.22.
This script will consider the input image for constructing the radial profile around a given center with ellipti‐
cal apertures.
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-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 de‐
velopers. For more information, please run:
$ info help-gnuastro
astscript-radial-profile options:
Input:
-h, --hdu=STR
HDU/extension of all input FITS files.
-O, --mode=STR
Coordinate mode: img or wcs.
-c, --center=FLT,FLT
Coordinate of the center along 2 axes.
-R, --rmax=FLT
Maximum radius for the radial profile (in pixels).
-Q, --axis-ratio=FLT
Axis ratio for ellipse profiles (A/B).
-a, --azimuth=FLT,FLT
Azimuthal angles range (from the major axis).

Output:
-o, --output
Output table with the radial profile.
-t, --tmpdir
Directory to keep temporary files.
-k, --keeptmp
Keep temporal/auxiliar files.
-m, --measure=STR
Measurement operator (mean, sigclip-mean, etc.).
-P, --precision=INT
Number of digits after the decimal point for radius.
-v, --oversample=INT
Oversample for higher resolution radial profile.
-u, --undersample=INT
Undersample for lower resolution radial profile.
-i, --instd=FLT/STR
Sky standard deviation per pixel, as a single number or as the filename.
-d, --stdhdu=STR
HDU/extension of the sky standard deviation image.
Operating mode:
-?, --help
Print this help list.
--cite BibTeX citation for this program.

-V, --version
Print program version.
Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short op‐
tions.
