Input files: DO category: Type: Explanation: Required:\ DARK Raw Dark exposure Y\ MASTER\_BIAS Calib Master bias Y\ CCD\_TABLE Calib Bad pixel table . Output files: DO category: Data type: Explanation:\ MASTER\_DARK FITS image Master dark A CCD table must be specified only if a bad pixel cleaning is requested. For more details, please refer to the VIMOS Pipeline User´s Guide. ## OPTIONS - **--AllowSingleFrames** *\* Frame combination method is ignored. (bool; default: True). The full name of this option for the EsoRex configuration file is **vimos.Parameters.stacking.singleframes** \[default = *True*\]. - **--StackMethod** *\* Frame combination method. (str; default: ´Median´). The full name of this option for the EsoRex configuration file is **vimos.Parameters.stacking.method** \[default = *Median*\]. - **--KSigmaLow** *\* Low threshold for K-sigma clipping method. (float; default: 5.0). The full name of this option for the EsoRex configuration file is **vimos.Parameters.stacking.ksigma.low** \[default = *5.0*\]. - **--KSigmaHigh** *\* High threshold for K-sigma clipping method. (float; default: 5.0). The full name of this option for the EsoRex configuration file is **vimos.Parameters.stacking.ksigma.high** \[default = *5.0*\]. - **--MinRejection** *\* Number of lowest rejected values for rejection method. (int; default: 1). The full name of this option for the EsoRex configuration file is **vimos.Parameters.stacking.minmax.minimum** \[default = *1*\]. - **--MaxRejection** *\* Number of highest rejected values for rejection method. (int; default: 1). The full name of this option for the EsoRex configuration file is **vimos.Parameters.stacking.minmax.maximum** \[default = *1*\]. - **--BiasMethod** *\* Bias removal method. (str; default: ´Zmaster´). The full name of this option for the EsoRex configuration file is **vimos.Parameters.bias.removing.method** \[default = *Zmaster*\]. - **--CleanBadPixel** *\* Bad pixel correction on master dark. (bool; default: False). The full name of this option for the EsoRex configuration file is **vimos.Parameters.badpixel.clean** \[default = *False*\]. - **--CleanCosmic** *\* Cosmic ray events cleaning from raw darks. (bool; default: True). The full name of this option for the EsoRex configuration file is **vimos.Parameters.cosmics.clean** \[default = *True*\]. - **--CosmicThreshold** *\* Threshold to identify cosmic rays candidates. (float; default: 4.0). The full name of this option for the EsoRex configuration file is **vimos.Parameters.cosmics.threshold** \[default = *4.0*\]. - **--CosmicRatio** *\* Min ratio between peak and nearby pixels for a cosmic ray. (float; default: 2.0). The full name of this option for the EsoRex configuration file is **vimos.Parameters.cosmics.ratio** \[default = *2.0*\]. - **--ComputeQC** *\* Compute QC1 parameters (bool; default: True). The full name of this option for the EsoRex configuration file is **vimos.Parameters.quality.enable** \[default = *True*\]. Note that it is possible to create a configuration file containing these options, along with suitable default values.

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.
