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.
