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.
