astscript-psf-subtract [
OPTION]
FITS-files
This script is part of GNU Astronomy Utilities 0.19.
This script will place the given PSF image into a certain central position with
the image and subtract it.
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-psf-subtract
- 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
- Input:
-
-h, --hdu=STR
- HDU/extension of all input FITS files.
-
-p, --psf=STR
- PSF FITS image.
-
-P, --psfhdu=STR
- HDU/extension of the PSF image.
-
-O, --mode=STR
- Coordinates mode ('wcs' or 'img').
-
-c, --center=FLT,FLT
- Center coordinates of the object.
-
