NAME

       vimos_ima_dark - Dark combination for imaging

SYNOPSIS

       esorex vimos_ima_dark [OPTIONS] FILE.sof

DESCRIPTION

       vimos_ima_dark -- VIMOS dark combine recipe.

       Combine  a list of dark frames into a mean dark frame. Optionally compare the output frame
       to a reference dark frame

       The program accepts the following files in the SOF:

           Tag                   Description

           DARK                  A list of raw dark images
           MASTER_BIAS           A master bias frame
           REFERENCE_DARK        Optional reference dark frame
           MASTER_BPM            Optional master bad pixel map or
           MASTER_CONF           Optional master confidence map If no  reference  dark  frame  is
       made  available,  then  no  comparison  will  be  done. This means there will be no output
       difference image and no stats tableIf neither a master bad pixel map nor confidence map is
       provided then thestats will be done assuming all pixels are good

OPTIONS

       --combtype <str>
              Combination  algorithm  (str;  default: ´median´). The full name of this option for
              the EsoRex configuration file is vimos.vimos_ima_dark.combtype [default = median].

       --scaletype <str>
              Scaling algorithm (str; default: ´exptime´). The full name of this option  for  the
              EsoRex configuration file is vimos.vimos_ima_dark.scaletype [default = exptime].

       --xrej <bool>
              True  if  using  extra rejection cycle (bool; default: True). The full name of this
              option for the EsoRex configuration file is  vimos.vimos_ima_dark.xrej  [default  =
              True].

       --thresh <float>
              Rejection  threshold in sigma above background (float; default: 5.0). The full name
              of this option for the EsoRex  configuration  file  is  vimos.vimos_ima_dark.thresh
              [default = 5.0].

       --ncells <int>
              Number  of  cells  for  diff  image  stats (int; default: 8). The full name of this
              option for the EsoRex configuration file is vimos.vimos_ima_dark.ncells [default  =
              8].

       --prettynames <bool>
              Use  pretty output file names? (bool; default: False). The full name of this option
              for the EsoRex configuration file is  vimos.vimos_ima_dark.prettynames  [default  =
              False].

       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.
