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.
