vmimflatsky(7) Create a master sky flat field from set of raw sky flat field frames.

SYNOPSIS

esorex vmimflatsky [OPTIONS] FILE.sof

DESCRIPTION

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.

OPTIONS

--SmoothBoxSize <long>
Size of running box used for smoothing (long; default: 7). The full name of this option for the EsoRex configuration file is vimos.Parameters.smooth.boxsize [default = 7].
--SmoothMethod <str>
Smooth method for image trends removal (str; default: 'Median'). The full name of this option for the EsoRex configuration file is vimos.Parameters.smooth.method [default = Median].
--AllowSingleFrames <bool>
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 <str>
Frames combination method (str; default: 'Median'). The full name of this option for the EsoRex configuration file is vimos.Parameters.stacking.method [default = Median].
--KSigmaLow <float>
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 <float>
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 <long>
Number of lowest rejected values for rejection method (long; default: 1). The full name of this option for the EsoRex configuration file is vimos.Parameters.minmax.minimum [default = 1].
--MaxRejection <long>
Number of highest rejected values for rejection method (long; default: 1). The full name of this option for the EsoRex configuration file is vimos.Parameters.minmax.maximum [default = 1].
--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.
