ASTSCRIPT-RADIAL-PROFILE(1)

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 0.24.

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

  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 range(s) (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.

-i, --instd=FLT/STR
    Sky standard deviation per pixel, as a single number or as the filename (given to MakeCatalog).

-d, --stdhdu=STR
    HDU/extension of the sky standard deviation image.

    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.

    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.
