NAME

       uves_cal_cd_align - Measures the reproducability of the cross disperser positioning

SYNOPSIS

       esorex uves_cal_cd_align [OPTIONS] FILE.sof

DESCRIPTION

       Given two input frames (CD_ALIGN_xxx where xxx = BLUE or RED) which contain only one echelle order, this
       recipe measures the shift in the cross-dispersion direction of that order. For RED input frames, only the
       lower chip is processed.

       The recipe produces a CD_ALIGN_TABLE_xxxx (with xxxx = BLUE or REDL) with columns X:         Column
       number YCENi:     Centroid from Gaussian fit (for i = 1,2) SIGMAi:    Stdev from Gaussian fit BACKi:
       Constant background from Gaussian fit NORMi:     Normalization constant from Gaussian fit YDIFF:
       Difference YCEN2 - YCEN1 of centroid positions

       and the QC-parameters ESO.QC.YDIFF(AVG|MED|RMS), which are the average, median and root-mean-square of
       the y-shift, respectively.

OPTIONS

       --debug <bool>
              Whether or not to save intermediate results to local directory (bool; default: False). The full
              name of this option for the EsoRex configuration file is uves.debug [default = False].

       --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].

       --steps <long>
              Step size in pixels (long; default: 100). The full name of this option for the EsoRex
              configuration file is uves_cal_cd_align.steps [default = 100].

       --xborder <long>
              Exclude a border region of this size (pixels) (long; default: 200). The full name of this option
              for the EsoRex configuration file is uves_cal_cd_align.xborder [default = 200].

       --window <long>
              The half window height used for Gaussian fitting (long; default: 50). The full name of this option
              for the EsoRex configuration file is uves_cal_cd_align.window [default = 50].

       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.
