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.
