Generating a .psf file from .fits file

[krittisharma]

Hi! I have a fits file which contains my synthetic PSF model which I want to feed into SExtractor. Is there any code snippet available to convert this fits file into .psf format which is accepted by SExtractor?

I am not sure it is the best way, but I would simply run PSFEx on the FITS image of your synthetic model...
