NAME

       hawki_step_refine_offsets - Jitter recipe

SYNOPSIS

       esorex hawki_step_refine_offsets [OPTIONS] FILE.sof

DESCRIPTION

       hawki_step_refine_offsets -- utility to refine the nominal offsets.

       This utility will take the offsets in the header as a first approach and tries to refine them correlating
       the input images at the points given by the detected objects.

       The  input  of  the  recipe  files  listed in the Set Of Frames (sof-file) must be tagged as: images.fits
       DIST_CORRECTED or images.fits BKG_SUBTRACTED and det_obj_stats.fits OBJ_PARAM The recipe  creates  as  an
       output:  hawki_step_refine_offsets.fits (OFFSETS_REFINED): Table with refined offsets Return code: esorex
       exits with an error code of 0 if the recipe completes successfully or 1 otherwise

OPTIONS

       --xcorr <str>
              Cross correlation search and measure sizes (str; default: ´20,20,25,25´). The full  name  of  this
              option  for  the  EsoRex  configuration  file  is hawki.hawki_step_refine_offsets.xcorr [default =
              20,20,25,25].

       --nbrightest <long>
              Number of brightest objects to use (long; default: 3). The full name of this option for the EsoRex
              configuration file is hawki.hawki_step_refine_offsets.nbrightest [default = 3].

       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.
