NAME

       visir_img_dark - Dark recipe

SYNOPSIS

       esorex visir_img_dark [OPTIONS] FILE.sof

DESCRIPTION

       This recipe computes the dark.

       The   files   listed   in   the   Set   Of   Frames   (sof-file)  must  be  tagged  either
       VISIR-dark-image-raw-file.fits     IM_CAL_DARK     or     VISIR-dark-spectro-raw-file.fits
       SPEC_CAL_DARK

       The  corresponding  four  products will each have a FITS card ´HIERARCH ESO PRO CATG´ with
       values (for imaging) IMG_DARK_AVG IMG_DARK_HOT IMG_DARK_COLD IMG_DARK_DEV
         or (for spectroscopy) SPEC_DARK_AVG SPEC_DARK_HOT SPEC_DARK_COLD SPEC_DARK_DEV

OPTIONS

       --r <str>
              Rejected left right bottom and top border (pixel) (str; default: ´50  50  50  50´).
              The   full   name   of   this   option   for   the  EsoRex  configuration  file  is
              visir.visir_img_dark.rej_bord [default = 50 50 50 50].

       --hot_t <float>
              Hot pixel map threshold (float; default: 10.0). The full name of  this  option  for
              the  EsoRex  configuration  file  is  visir.visir_img_dark.hot_threshold [default =
              10.0].

       --cold_t <float>
              Cold pixel map threshold (float; default: 6.0). The full name of  this  option  for
              the  EsoRex  configuration  file  is visir.visir_img_dark.cold_threshold [default =
              6.0].

       --dev_t <float>
              Deviant pixel map threshold (float; default: 5.0). The full name of this option for
              the  EsoRex  configuration  file  is  visir.visir_img_dark.dev_threshold [default =
              5.0].

       --nsamples <int>
              Number of samples for Read-Out Noise (RON) computation  (int;  default:  100).  The
              full    name    of   this   option   for   the   EsoRex   configuration   file   is
              visir.visir_img_dark.nsamples [default = 100].

       --hsize <int>
              Half size of the window for Read-Out Noise (RON) computation (int; default: 2). The
              full    name    of   this   option   for   the   EsoRex   configuration   file   is
              visir.visir_img_dark.hsize [default = 2].

       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.
