       hawki_linearity_analyse -- HAWKI detector linearity recipe.

       Check  the  linearity of the HAWKI detectors on a pixel by pixel basis The program accepts
       the following files in the SOF:

           Tag                   Description

           DARK_DETCHECK         A list of dark images
           FLAT_LAMP_DETCHECK    A list of dome flat images All of the above  are  required.  The
       should be a dark frame for each DIT/NDITcombination used for the dome flats


       --order <int>
              Polynomial  order  to  fit  (int; default: 3). The full name of this option for the
              EsoRex configuration file is hawki.hawki_linearity_analyse.order [default = 3].

       --fitzero <bool>
              Fit zeroth order term? (bool; default: False). The full name of this option for the
              EsoRex  configuration  file  is  hawki.hawki_linearity_analyse.fitzero  [default  =

       --rchithr <float>
              Maximum allowable value of reduced chisq? (float; default: 5.0). The full  name  of
              this      option      for      the      EsoRex      configuration      file      is
              hawki.hawki_linearity_analyse.rchithr [default = 5.0].

       --satlim <float>
              Saturation limit? (float; default: 65535.0). The full name of this option  for  the
              EsoRex   configuration  file  is  hawki.hawki_linearity_analyse.satlim  [default  =

       --reflev <float>
              Reference flux level for NL check (float; default: 10000.0). The full name of  this
              option  for  the  EsoRex configuration file is hawki.hawki_linearity_analyse.reflev
              [default = 10000.0].

       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'


       The full documentation for the hawki pipeline can be downloaded as a PDF  file  using  the
       following URL:


       An   overview   over   the   existing   ESO  pipelines  can  be  found  on  the  web  page

       Basic documentation about the EsoRex program can be found at the esorex (1) man page.

       It is possible to call the pipelines  from  python  using  the  python-cpl  package.   See for further information.
