    PSF model: checking that a PSF image is given for computing flux factor
    
    Until this commit, the script that computes the flux factor was not
    checking if a PSF image was given. This was causing the script to crash and
    it took to me a while to notice that error.  With this commit, I have added
    a check to ensure that a PSF image is provided with the option '--psf'. If
    the user does not provide it, the script will crash and warn about this
    problem with a good message.
