Create a master sky flat field from set of raw sky flat field frames.
esorex vmimflatsky [OPTIONS] FILE.sof
This recipe is used to create a master sky flat field from a set of raw sky flat fields. The master sky flat field is the dataset used for the flat field correction of scientific data.
Input files:
DO category: Type: Explanation: Required: IMG_SKY_FLAT Raw Sky flat exposure Y MASTER_BIAS Calib Master bias Y MASTER_DARK Calib Master dark .
IMG_MASTER_SCREEN_FLAT Calib Master screen flat .
CCD_TABLE Calib Bad pixel table .
Output files:
DO category: Data type: Explanation: IMG_MASTER_SKY_FLAT FITS image Master sky flat field
If a master screen flat is specified, the input sky flat exposures are flat-fielded with it, and then just used to determine the large scale trends of the instrument response; the result is then multiplied by the master screen flat. A CCD table must be specified in input only if a bad pixel cleaning is requested.
For more details, please refer to the VIMOS Pipeline User\'s Guide.

--BiasMethod <str>
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 <bool>
Bad pixel correction on master flat (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.badpixel.clean [default = False].
--CleanCosmic <bool>
Cosmic ray events cleaning from raw flats (bool; default: False). The full name of this option for the EsoRex configuration file is vimos.Parameters.cosmics.clean [default = False].
--CosmicThreshold <float>
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 <float>
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 <bool>
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. Please refer to the details provided by the 'esorex --help' command.
