vmimflatsky - 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.

Size of running box used for smoothing (int; default: 7). The full name of this option for the EsoRex configuration file is vimos.Parameters.smooth.boxsize [default = 7].

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].
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].
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].
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].
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.
