Make normalized stamp with other sources masked

Synopsis

astscript-psf-stamp [OPTION] FITS-files

Description

This script is part of GNU Astronomy Utilities 0.23.

This script will consider a center position to make a normalized stamp. It is intendeed to generate several stamps and combine them to obtain a PSF.

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.

astscript-psf-stamp options

Input:

-h, --hdu=STR: HDU/extension of all input FITS files.
-O, --mode=STR: Coordinates mode ('wcs' or 'img').
-c, --center=FLT,FLT: Center coordinates of the object.

-W, --widthinpix=INT,INT Width of the stamp in pixels.

-T, --snthresh=FLT: Mask pixels below this S/N (only when '--segment' is given).
-n, --normradii=INT,INT Minimum and maximum radii (in pixels): for computing the normalization value.
-S, --segment=STR: Output of Segment (with OBJECTS and CLUMPS).
-N, --normop=STR: Operator for computing the normalization value (mean, sigclip-mean, etc.).
-Q, --axis-ratio=FLT: Axis ratio for ellipse maskprofile (A/B).
