SYNOPSIS

esorex hawki_sci_jitter [OPTIONS] FILE.sof

DESCRIPTION

hawki_sci_jitter -- hawki imaging jitter recipe.

The input of the recipe files listed in the Set Of Frames (sof-file) must be tagged as: raw-file.fits JITTER_OBS or raw-file.fits JITTER_SKY or flat-file.fits FLAT_IM or dark-file.fits DARK_IM bpm-file.fits BPM distortion_x-file.fits DISTORTION_X distortion_y-file.fits DISTORTION_Y

The recipe creates as an output: hawki_sci_jitter.fits (COMBINED) hawki_sci_jitter_stitched.fits (STITCHED) hawki_sci_jitter_stars.fits (OBJ_PARAM): Detected objects properties hawki_sci_jitter_stats.fits (JITTER_STATS): Stats of the individual images hawki_sci_jitter_bkg_stats.fits (BKG_STATS): Statistics on the bkg

The recipe performs the following steps: 1) Frame statistics 2) Basic reduction (using FLAT_IM and BPM) 3) Background computation (the algorithm depends on parameter --sky_par) 4) Offset refinement (uses parameters --off, --refine and --xcorr) 5) Stacking of jitter frames (uses --comb_meth, --rej,

   --offset_max, --borders, --max_njitter)

6) Stitching of the four detectors into one image 7) Object detection in the stacked image

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

OPTIONS

--offsets <str>

offsets file (str; default: None). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.offsets [default = None].

--objects <str>

objects file (str; default: None). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.objects [default = None].

--offset_max <long>

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

--sky_par <str>

Rejection parameters for sky filtering (str; default: \'10,7,3,3\'). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.sky_par [default = 10,7,3,3].

--refine <bool>

refine offsets (bool; default: False). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.refine [default = False].

--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_sci_jitter.xcorr [default = 20,20,25,25].

--comb_meth <str>

union / inter / first (str; default: \'union\'). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.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_sci_jitter.rej [default = 1,1].

--borders <long>

Borders rejected (long; default: 4). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.borders [default = 4].

--max_njitter <long>

Maximum numbers of jitter frames to combine (long; default: -1). The full name of this option for the EsoRex configuration file is hawki.hawki_sci_jitter.max_njitter [default = -1].

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.
