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.
