uves_cal_cd_align - Measures the reproducability of the cross disperser

UVES_CAL_CD_ALIGN(7) uves recipes UVES_CAL_CD_ALIGN(7)

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.
