NAME

       visir_util_clip - Kappa-sigma clipping of outliers for each pixel

SYNOPSIS

       esorex visir_util_clip [OPTIONS] FILE.sof

DESCRIPTION

       The   files   listed   in   the  Set  Of  Frames  (sof-file)  must  be  tagged  pair-wise:
       VISIR-raw-file.fits RAW VISIR-bpm-file.fits BPM

       The product(s) will have a FITS card ´HIERARCH ESO PRO CATG´ with  a  value  of:  BPM  The
       outliers are marked as rejected in the matching bad pixel map.

OPTIONS

       --keepfrac <float>
              The  fraction  of  pixels  to keep for the initialmedian (float; default: 0.9). The
              full   name   of   this   option   for   the   EsoRex   configuration    file    is
              visir.visir_util_clip.keepfrac [default = 0.9].

       --kappa <float>
              Clip  outside  + or - kappa * sigma (the standard deviation) (float; default: 5.0).
              The  full  name  of  this   option   for   the   EsoRex   configuration   file   is
              visir.visir_util_clip.kappa [default = 5.0].

       --maxite <int>
              Max  number  of kappa-sigma clipping iterations (int; default: 3). The full name of
              this option for  the  EsoRex  configuration  file  is  visir.visir_util_clip.maxite
              [default = 3].

       --shift-beams <bool>
              Account for movements of the object defined in CRPIX[12] (bool; default: True). The
              full   name   of   this   option   for   the   EsoRex   configuration    file    is
              visir.visir_util_clip.shift-beams [default = True].

       --error-source <str>
              Defines  the way errors are generated:  img-stdev: stdev of image timeseries: stdev
              of each pixel over the time axis of the  cube   none:  no  error  generation  (str;
              default:  ´img-stdev´).  The  full name of this option for the EsoRex configuration
              file is visir.visir_util_clip.error-source [default = img-stdev].

       --error-out-type <str>
              Output clipped error as error, variance, weight or none  (str;  default:  ´error´).
              The   full   name   of   this   option   for   the  EsoRex  configuration  file  is
              visir.visir_util_clip.error-out-type [default = error].

       --badimage <float>
              If percentage of clipped pixels above this value the whole image is considered  bad
              (float;  default:  0.2).  The full name of this option for the EsoRex configuration
              file is visir.visir_util_clip.badimage [default = 0.2].

       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.
