OPTIONS

       --stack_method <str>
              Frames  combination  method  (str; default: ´median´). The full name of this option for the EsoRex
              configuration file is fors.fors_img_sky_flat.stack_method [default = median].

       --minrejection <int>
              Number of lowest values to be rejected (int; default: 1). The full name of  this  option  for  the
              EsoRex configuration file is fors.fors_img_sky_flat.minrejection [default = 1].

       --maxrejection <int>
              Number  of  highest  values to be rejected (int; default: 1). The full name of this option for the
              EsoRex configuration file is fors.fors_img_sky_flat.maxrejection [default = 1].

       --klow <float>
              Low threshold in ksigma method (float; default: 3.0). The full name of this option for the  EsoRex
              configuration file is fors.fors_img_sky_flat.klow [default = 3.0].

       --khigh <float>
              High threshold in ksigma method (float; default: 3.0). The full name of this option for the EsoRex
              configuration file is fors.fors_img_sky_flat.khigh [default = 3.0].

       --kiter <int>
              Max number of iterations in ksigma method (int; default: 999). The full name of  this  option  for
              the EsoRex configuration file is fors.fors_img_sky_flat.kiter [default = 999].

       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.
