astscript-psf-scale-factor - Find factor to scale PSF to a given star in an image
astscript-psf-scale-factor [OPTION] FITS-files
This script is part of GNU Astronomy Utilities 0.18. This script will consider a center position and then compute the factor by which it is necessary to multiply the specified PSF image in order to match it with the object at the center (within a ring radii). The main idea is to have the necessary factor that will be used to allocate the PSF with the proper flux value for constructing the scattered light field. 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-scale-factor 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-psf-scale-factor options: Input: -h, --hdu=STR HDU/extension of all input FITS files. -p, --psf=STR PSF image fits file. -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. -W, --stampwidth=INT Width of the stamp in pixels. -n, --normradii=INT,INT Minimum and maximum radii (in pixels) for computing the scaling factor value. -S, --segment=STR Output of Segment (with OBJECTS and CLUMPS). -s, --sigmaclip=FLT,FLT Sigma-clip multiple and tolerance. Output: -t, --tmpdir Directory to keep temporary files. -k, --keeptmp Keep temporal/auxiliar files. 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. GNU Astronomy Utilities home page: http://www.gnu.org/software/gnuastro/
