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 0.23.

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:

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).

-p, --position-angle=FLT Position angle for ellipse profiles.

-g, --polar: Polar plot (azimuth angle vs. radius).
-s, --sigmaclip=FLT,FLT: Sigma-clip multiple and tolerance.
-z, --zeropoint=FLT: Zeropoint magnitude of input dataset.
-Z, --zeroisnotblank: 0.0 in float or double images are not blank.

: 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 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.
-q, --quiet: Don't print any extra information in stdout.
-V, --version: Print program version.

Mandatory or optional arguments to long options are also mandatory or optional for any corresponding short options.
