OPTIONS

       --fitz <bool>
              Fit  zeropoint  (bool;  default:  True). The full name of this option for the EsoRex configuration
              file is fors.fors_photometry.fitz [default = True].

       --fit_all_mag <bool>
              Always fit star magnitudes (bool; default: False). The full name of this  option  for  the  EsoRex
              configuration file is fors.fors_photometry.fit_all_mag [default = False].

       --fite <str>
              Fit  atmospheric  extinctions  (str;  default:  ´pernight´).  The full name of this option for the
              EsoRex configuration file is fors.fors_photometry.fite [default = pernight].

       --fitc <bool>
              Fit color correction term (bool; default: False). The full name of  this  option  for  the  EsoRex
              configuration file is fors.fors_photometry.fitc [default = False].

       --use_all_stars <bool>
              Use  also  non-standard  stars  to  fit polynomial f (bool; default: False). The full name of this
              option for the EsoRex configuration file is fors.fors_photometry.use_all_stars [default = False].

       --degreef1 <int>
              FLatfield correction map polynomial degree (x) (int; default: 0). The full name of this option for
              the EsoRex configuration file is fors.fors_photometry.degreef1 [default = 0].

       --degreef2 <int>
              Flatfield correction map polynomial degree (y), or  negative  for  triangular  coefficient  matrix
              (int;  default:  -1).  The  full  name  of  this  option  for  the  EsoRex  configuration  file is
              fors.fors_photometry.degreef2 [default = -1].

       --degreep <int>
              Extinction/color coupling degree (int; default: 0). The full name of this option  for  the  EsoRex
              configuration file is fors.fors_photometry.degreep [default = 0].

       --mjd_obs_target <float>
              MJD-OBS  used  to  match  the  raw  frame  from  which EXTINCTION_PER_NIGHT and PHOT_COEFF inherit
              MJD-OBS. If negative theMJD-OBS of the first raw frame isused (float;  default:  -1.0).  The  full
              name  of  this  option  for  the  EsoRex configuration file is fors.fors_photometry.mjd_obs_target
              [default = -1.0].

       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.
