hawki_step_combine (7)

esorex hawki_step_combine [OPTIONS] FILE.sof

hawki_step_combine -- hawki combine jitter images.

The files listed in the Set Of Frames (sof-file) must be tagged: science-file.fits DIST_CORRECTED or science-file.fits BKG_SUBTRACTED or bpm-file.fits BPM (optional) bkg_bpm-file.fits BKG_BPM (optional) offsets-file.fits OFFSETS_REFINED (optional) The recipe creates as an output: hawki_step_combine.fits (COMBINED): The recipe does the following steps: -Allocate an image with the proper combined size

   (depends on parameters --comb_meth and --borders)

-Retrieve the offsets either from the offsets-file.fits or from the header -For each combined pixel, the contribution of each individual frame

   is added using a resampling kernel. If any of the pixels involved in
   the resampling is a bad pixel (defined in bpm-file.fits), it is not
   taken into account.

   With the remaining pixels a minmax rejection is performed

Return code: esorex exits with an error code of 0 if the recipe completes successfully or 1 otherwise

--offset_max <long>

Maximum offset allowed (long; default: 1500). The full name of this option for the EsoRex configuration file is hawki.hawki_step_combine.offset_max [default = 1500].

--comb_meth <str>

Final size of combination (union / inter / first) (str; default: \'union\'). The full name of this option for the EsoRex configuration file is hawki.hawki_step_combine.comb_meth [default = union].

--rej <str>

Low and high number of rejected values (str; default: \'1,1\'). The full name of this option for the EsoRex configuration file is hawki.hawki_step_combine.rej [default = 1,1].

--borders <long>

Border pixels trimmed (long; default: 4). The full name of this option for the EsoRex configuration file is hawki.hawki_step_combine.borders [default = 4].

--resamp_kernel <str>

Resampling kernel (default/tanh/sinc/sinc2/lanczos/hamming/hann) (str; default: \'default\'). The full name of this option for the EsoRex configuration file is hawki.hawki_step_combine.resamp_kernel [default = default].

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.
