hawki_step_refine_offsets - (OBSOLETE) Jitter recipe


esorex hawki_step_refine_offsets [OPTIONS] FILE.sof


(OBSOLETE) 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


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].
Number of brightest objects to use (int; 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.
