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.
