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.
