Parameters:

  • image (str) – name of the FITS image that contains the galaxy model

  • GAIN (float) – CCD’s gain e-/ADU

  • skymean (float) – value of the mean of sky background

  • skystd (float) – value of standard deviation of sky background

  • newimage (str) – name of the new simulated image
