Filter switch (str; default: ´none´). The full name of this option for the EsoRex configuration file is flames_obs_scired.filt_sw [default = none].

--merge <str>

Order merging method. If ´optimal´, the flux in the overlapping region is set to the (optimally computed, using the uncertainties) average of single order spectra. If ´sum´, the flux in the overlapping region is computed as the sum of the single order spectra. If flat-fielding is done, method ´optimal´ is recommended, otherwise ´sum´. (str; default: ´optimal´). The full name of this option for the EsoRex configuration file is flames_obs_scired.merge [default = optimal].

--merge_delt1 <float>

Order merging left hand (short wavelength) cut. To reduce the amount of order overlapping regions we allow to cut short and long wavelength ranges. This may reduce the ripple possibly introduced by the order merging. Suggested values are: 10 (W<=390), 12 (390<W<=437, 520<W<=564), 14 (437<W<=520, 564<W<860), 4 (W>=860) (float; default: -1.0). The full name of this option for the EsoRex configuration file is flames_obs_scired.merge_delt1 [default = -1.0].

--merge_delt2 <float>

Order merging right hand (long wavelength) cut. To reduce the amount of order overlapping regions we allow to cut short and long wavelength ranges. This may reduce the ripple possibly introduced by the order merging. Suggested values is 4 for W<860, else 0 (float; default: -1.0). The full name of this option for the EsoRex configuration file is flames_obs_scired.merge_delt2 [default = -1.0].

--pixel_thresh_max <int>

Pixel saturation threshold max (int; default: 55000). The full name of this option for the EsoRex configuration file is flames_obs_scired.pixel_thresh_max [default = 55000].

--pixel_thresh_min <int>

Pixel saturation threshold min (int; default: -20). The full name of this option for the EsoRex configuration file is flames_obs_scired.pixel_thresh_min [default = -20].

--plotter <str>

Any plots produced by the recipe are redirected to the command specified by this parameter. The plotting command must contain the substring ´gnuplot´ and must be able to parse gnuplot syntax on its standard input. Valid examples of such a command may include ´gnuplot -persist´ and ´cat > mygnuplot$$.gp´. A finer control of the plotting options can be obtained by writing an executable script, e.g. my_gnuplot.pl, that executes gnuplot after setting the desired gnuplot options (e.g. set terminal pslatex color). To turn off plotting, set this parameter to ´no´ (str; default: ´no´). The full name of this option for the EsoRex configuration file is uves.plotter [default = no].

--process_chip <str>

For RED arm data process the redl, redu, or both chip(s) (str; default: ´both´). The full name of this option for the EsoRex configuration file is uves.process_chip [default = both].

--rebin.scale <bool>

Whether or not to multiply by the factor dx/dlambda (pixels per wavelength) during the rebinning to conserve the flux. This option is disabled as default because applying the flat field correction already ensures flux conservation. Therefore this parameter should be TRUE (for response and science data) only if reduce.ffmethd = no. (bool; default: False). The full name of this option for the EsoRex configuration file is flames_obs_scired.rebin.scale [default = False].

--rebin.wavestep <float>

The bin size used for BLUE/REDL data (in w.l.u.) in wavelength space. If negative, a step size of 2/3 * ( average pixel size ) is used. (float; default: -1.0). The full name of this option for the EsoRex configuration file is flames_obs_scired.rebin.wavestep [default = -1.0].

--rebin.wavestep_redu <float>

The bin size used for REDU data (in w.l.u.) in wavelength space. If negative, a step size of 2/3 * ( average pixel size ) is used. (float; default: -1.0). The full name of this option for the EsoRex configuration file is flames_obs_scired.rebin.wavestep_redu [default = -1.0].

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.
