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.
