OPTIONS

       --sex_exe <str>
              SExtractor  executable (str; default: ´/usr/bin/sex´). The full name of this option
              for  the  EsoRex  configuration  file  is  fors.fors_zeropoint.sex_exe  [default  =
              /usr/bin/sex].

       --sex_config <str>
              SExtractor      configuration      file     (str;     default:     ´/usr/share/cpl-
              plugins/fors-4.11.12/config/fors.sex´). The full name of this option for the EsoRex
              configuration     file     is     fors.fors_zeropoint.sex_config     [default     =
              /usr/share/cpl-plugins/fors-4.11.12/config/fors.sex].

       --sex_mag <str>
              SExtractor magnitude (str; default: ´MAG_APER´). The full name of this  option  for
              the EsoRex configuration file is fors.fors_zeropoint.sex_mag [default = MAG_APER].

       --sex_magerr <str>
              SExtractor  magnitude  error  (str;  default: ´MAGERR_APER´). The full name of this
              option for the EsoRex configuration file is fors.fors_zeropoint.sex_magerr [default
              = MAGERR_APER].

       --sex_radius <long>
              Background  error  map  median filter radius (unbinned pixels) (long; default: 64).
              The  full  name  of  this   option   for   the   EsoRex   configuration   file   is
              fors.fors_zeropoint.sex_radius [default = 64].

       --maxoffset <float>
              Maximum  acceptable  offset  between  the  image and catalogue WCS (pixels) (float;
              default: 150.0). The full name of this option for the EsoRex configuration file  is
              fors.fors_zeropoint.maxoffset [default = 150.0].

       --magcutE <float>
              Zeropoint  absolute cutoff (magnitude) (float; default: 1.0). The full name of this
              option for the EsoRex configuration file is fors.fors_zeropoint.magcutE [default  =
              1.0].

       --magcutk <float>
              Zeropoint  kappa  rejection  parameter (float; default: 5.0). The full name of this
              option for the EsoRex configuration file is fors.fors_zeropoint.magcutk [default  =
              5.0].

       --magsyserr <float>
              Systematic  error in magnitude (float; default: 0.01). The full name of this option
              for the EsoRex  configuration  file  is  fors.fors_zeropoint.magsyserr  [default  =
              0.01].

       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.
