NAME

       kmos_illumination - Create a frame to correct spatial non-uniformity of flatfield

SYNOPSIS

       esorex kmos_illumination [OPTIONS] FILE.sof

DESCRIPTION

       This  recipe  creates  the  spatial  non-uniformity calibration frame needed for all three
       detectors. It must be called after the kmo_wave_cal-recipe, which generates  the  spectral
       calibration frame needed in this recipe. As input at least a sky or flat, a master dark, a
       master flat and the spatial and spectral calibration frames are required.

       The created product, the illumination correction, can be used as  input  for  kmo_std_star
       and kmo_sci_red.
