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.
