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

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

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