Systematic error in magnitude (float; default: 0.01). The full name of this option for the EsoRex configuration file is fors.fors_img_science.magsyserr [default = 0.01].
SExtractor executable (str; default: ´/usr/bin/source-extractor´). The full name of this option for the EsoRex configuration file is fors.fors_img_science.sex_exe [default = /usr/bin/source-extractor].
SExtractor configuration file (str; default: ´/usr/share/cpl- plugins/fors-5.5.7/config/fors.sex´). The full name of this option for the EsoRex configuration file is fors.fors_img_science.sex_config [default = /usr/share/cpl-plugins/fors-5.5.7/config/fors.sex].
SExtractor magnitude (str; default: ´MAG_APER´). The full name of this option for the EsoRex configuration file is fors.fors_img_science.sex_mag [default = MAG_APER].
SExtractor magnitude error (str; default: ´MAGERR_APER´). The full name of this option for the EsoRex configuration file is fors.fors_img_science.sex_magerr [default = MAGERR_APER].
Background error map median filter radius (unbinned pixels) (int; default: 64). The full name of this option for the EsoRex configuration file is fors.fors_img_science.sex_radius [default = 64].
If TRUE compliant IDP science products are generated (bool; default: False). The full name of this option for the EsoRex configuration file is fors.fors_img_science.idp_generate [default = False].
Every pixel in the MASTER_SKY_FLAT_IMG below the threshold will be put to 0 in the weight-map, 1 otherwise. Ignored if IDP generation is not requested (float; default: 0.5). The full name of this option for the EsoRex configuration file is fors.fors_img_science.idp_weights_threshold [default = 0.5].

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.

An overview over the existing ESO pipelines can be found on the web page https://www.eso.org/sci/software/pipelines/.

Basic documentation about the EsoRex program can be found at the esorex (1) man page.

It is possible to call the pipelines from python using the python-cpl package. See https://packages.python.org/python-cpl/index.html for further information.
