hawki_cal_flat(7) Twillight flat recipe

SYNOPSIS

esorex hawki_cal_flat [OPTIONS] FILE.sof

DESCRIPTION

hawki_cal_flat -- HAWKĪI imaging flat-field creation from twillight images.

The input of the recipe files listed in the Set Of Frames (sof-file) must be tagged as: raw-file.fits FLAT or Optional inputs are: bpmdark-file.fits BPM_HOT dark-file.fits DARK_IM dark_err-file.fits DARK_ERR The recipe creates as an output: hawki_cal_flat_setxx.fits (FLAT_IM): Master flat for filter xx hawki_cal_flat_err_setxx.fits (FLAT_ERRMAP): Master flat residuals hawki_cal_flat_bpmflat_setxx.fits (BPM_COLD): BPM from the flat hawki_cal_flat_stats_setxx.fits (FLAT_STATS): Stats of the individual flats Optionally it also creates: hawki_cal_flat_bpm_setxx.fits (BPM): Bad pixel mask combining bpm from dark and flat hawki_cal_flat_stats_ec_setxx.fits (FLAT_STATS_EVEN_COL): Stats of the individual flats for even columns hawki_cal_flat_stats_oc_setxx.fits (FLAT_STATS_ODD_COL): Stats of the individual flats for odd columns hawki_cal_flat_stats_er_setxx.fits (FLAT_STATS_EVEN_ROW): Stats of the individual flats for even rows hawki_cal_flat_stats_or_setxx.fits (FLAT_STATS_ODD_ROW): Stats of the individual flats for odd rows Return code: esorex exits with an error code of 0 if the recipe completes successfully or 1 otherwise

--lowval_bpm <float>
values of the flat below this will be included in the bpm. In units of final flat (normalised if normalise is on) (float; default: 0.1). The full name of this option for the EsoRex configuration file is hawki.hawki_cal_flat.lowval_bpm [default = 0.1].
--highval_bpm <float>
values of the flat above this will be included in the bpm. In units of final flat (normalized if normalise is on) (float; default: 10.0). The full name of this option for the EsoRex configuration file is hawki.hawki_cal_flat.highval_bpm [default = 10.0].
--select_auto <bool>
Flag to automatically select the good input frames (bool; default: True). The full name of this option for the EsoRex configuration file is hawki.hawki_cal_flat.select_auto [default = True].
--select_auto_max_bins <long>
