NAME

       gimasterbias - Creates a master bias image from a set of raw biases.

SYNOPSIS

       esorex gimasterbias [OPTIONS] FILE.sof

DESCRIPTION

       For detailed information please refer to the GIRAFFE pipeline user manual.

       It is available at http://www.eso.org/pipelines.

OPTIONS

       --stack-method <str>
              Stacking  method:  average,  median,  minmax or ksigma (str; default: ´average´). The full name of
              this option for the EsoRex configuration file is giraffe.stacking.method [default = average].

       --stack-ksigmalow <float>
              Lower threshold multiplier for method ksigma (float; default: 5.0). The full name of  this  option
              for the EsoRex configuration file is giraffe.stacking.ksigma.low [default = 5.0].

       --stack-ksigmahigh <float>
              Upper  threshold  multiplier for method ksigma (float; default: 5.0). The full name of this option
              for the EsoRex configuration file is giraffe.stacking.ksigma.high [default = 5.0].

       --stack-minreject <long>
              Minimum rejection level for method minmax (long; default: 1). The full name of this option for the
              EsoRex configuration file is giraffe.stacking.minmax.minimum [default = 1].

       --stack-maxreject <long>
              Maximum rejection level for method minmax (long; default: 1). The full name of this option for the
              EsoRex configuration file is giraffe.stacking.minmax.maximum [default = 1].

       --mbias-oscremove <bool>
              Remove pre- and over-scan regions from the created master bias image.  (bool; default: False). The
              full name of this option for the EsoRex configuration file  is  giraffe.masterbias.overscan.remove
              [default = False].

       --mbias-bpxclean <bool>
              Correct  master bias image for bad pixels (bool; default: False). The full name of this option for
              the EsoRex configuration file is giraffe.masterbias.badpixel.clean [default = False].

       --bpm-create <bool>
              Create bad pixel map using a simple thresholding algorithm.  (temporary!) (bool;  default:  True).
              The  full  name  of this option for the EsoRex configuration file is giraffe.masterbias.bpm.create
              [default = True].

       --bpm-factor <float>
              Readout noise multiplier defining the valid range  of  pixel  values  for  searching  bad  pixels.
              (float;  default:  5.0).  The  full  name  of  this  option  for  the EsoRex configuration file is
              giraffe.masterbias.bpm.factor [default = 5.0].

       --bpm-frac <float>
              Maximum fraction of pixels which may be flagged as ´bad. If more pixels are found  to  be  ´bad  a
              warning  is  issued.  (float;  default:  0.15).  The  full  name  of  this  option  for the EsoRex
              configuration file is giraffe.masterbias.bpm.fraction [default = 0.15].

       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.
