The full name of this option for the EsoRex configuration file is **fors.fors\_photometry.fitz** \[default = *True*\]. - **--fit\_all\_mag** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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** *\* 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. ## SEE ALSO The full documentation for the fors pipeline can be downloaded as a PDF file using the following URL: - **ftp://ftp.eso.org/pub/dfs/pipelines/fors/fors-pipeline-manual-4.9.pdf** 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.
