NAME
       fors_flatfield - Flat field correction of input frame


SYNOPSIS
       esorex fors_flatfield [OPTIONS] FILE.sof


DESCRIPTION
       This  recipe  is  used  to  divide  the input frame by the normalised flat field frame produced by recipe
       fors_normalise_flat. The input frame must be already bias subtracted (e.g., by recipe fors_remove_bias).

       In the table below the MXU acronym can be alternatively read as MOS and LSS.

       Input files:

         DO category:               Type:       Explanation:         Required:
         SCIENCE_UNBIAS_MXU
         or STANDARD_UNBIAS_MXU     Raw         Bias subtracted frame   Y
         MASTER_NORM_FLAT_MXU       Calib       Normalised flat frame   Y

       Output files:

         DO category:               Data type:  Explanation:
         SCIENCE_UNFLAT_MXU
         or STANDARD_UNFLAT_MXU     FITS image  Flat field corrected frame


OPTIONS
       Note that it is possible to create a configuration file containing these  options,  along  with  suitable
       default values. Please refer to the details provided by the 'esorex --help' command.
