NAME

       vmbias - Create a master bias from set of raw bias frames.

SYNOPSIS

       esorex vmbias [OPTIONS] FILE.sof

DESCRIPTION

       This recipe is used to create a master bias frame from a set of raw bias frames.

       Input files:

         DO category:  Type:       Explanation:     Required:
         BIAS          Raw         Bias exposure       Y
         CCD_TABLE     Calib       Bad pixel table     .

       Output files:

         DO category:  Data type:  Explanation:
         MASTER_BIAS   FITS image  Master bias

       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 <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>
              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 <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.stacking.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.stacking.minmax.maximum [default = 1].

       --RemoveOverscan <bool>
              Remove  overscan  regions  from master bias (bool; default: True). The full name of
              this      option      for      the      EsoRex      configuration      file      is
              vimos.Parameters.bias.overscan.remove [default = True].

       --CleanBadPixel <bool>
              Bad  pixel  correction on master bias (bool; default: False). The full name of this
              option for the EsoRex configuration  file  is  vimos.Parameters.bias.badpixel.clean
              [default = False].

       --CleanCosmic <bool>
              Cosmic ray removal from each raw bias (bool; default: False). The full name of this
              option for the EsoRex  configuration  file  is  vimos.Parameters.bias.cosmics.clean
              [default = False].

       --ComputeQC <bool>
              Compute  QC1 parameters (bool; default: True). The full name of this option for the
              EsoRex configuration file is vimos.Parameters.bias.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.
