NAME

       hawki_step_compute_bkg - (OBSOLETE) Background computing utility

SYNOPSIS

       esorex hawki_step_compute_bkg [OPTIONS] FILE.sof

DESCRIPTION

       (OBSOLETE) hawki_step_compute_bkg -- hawki background computation utility.

       This recipe will create the associated background images for a given set of object images.
       If there are sky images, these will be used to  compute  the  background,  otherwise,  the
       background  is computed using a running mean on the object images. An optional mask can be
       supplied for the running mean.

       The files listed in the Set Of Frames (sof-file) must be  tagged:  obj_basic_cal-file.fits
       BASIC_CALIBRATED or sky_basic_cal-file.fits SKY_BASIC_CALIBRATED and optionally for object
       masking: object_mask-file.fits  OBJ_MASK  offsets.fits  OFFSETS_REFINED  distortion_x.fits
       DISTORTION_X distortion_y.fits DISTORTION_Y

OPTIONS

       --nmin_comb <int>
              Minimum  number  of jitter frames to use the running median (int; default: 10). The
              full   name   of   this   option   for   the   EsoRex   configuration    file    is
              hawki.hawki_step_compute_bkg.nmin_comb [default = 10].

       --nhalf_window <int>
              Number  of images at both sides of the current ima to use for bkg in running median
              (int; default: 7). The full name of this option for the EsoRex  configuration  file
              is hawki.hawki_step_compute_bkg.nhalf_window [default = 7].

       --rejlow <int>
              The  number  of frames with low level to reject (int; default: 2). The full name of
              this      option      for      the      EsoRex      configuration      file      is
              hawki.hawki_step_compute_bkg.rejlow [default = 2].

       --rejhigh <int>
              The  number of frames with high level to reject (int; default: 2). The full name of
              this      option      for      the      EsoRex      configuration      file      is
              hawki.hawki_step_compute_bkg.rejhigh [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.
