visir_old_spc_wcal - Old DRS detector: Spectroscopic wavelength
calibration recipe
esorex visir_old_spc_wcal [OPTIONS] FILE.sof
This recipe estimates the dispersion relation using the
atmospheric spectrum in a long-slit spectroscopy half-cycle frame.
The files listed in the Set Of Frames (sof-file) must be tagged:
VISIR-Long-Slit-Spectroscopy-file.fits SPEC_CAL_LMR_WCAL
VISIR-Quantum-Efficiency-Calibration-file.fits SPEC_CAL_QEFF
VISIR-Atmospheric-Emission-Lines-Calibration-file.fits SPEC_CAL_LINES
Additionally, a bad pixel map with a PRO.CATG of SPEC_BPM may be
added to the Set Of Frames with tag: BPM.
- --auto_bpm
<bool>
- Automatic detection and correction of bad pixels (bool; default: True).
The full name of this option for the EsoRex configuration file is
visir.visir_old_spc_wcal.auto_bpm [default = True].
- --plot
<int>
- The recipe can produce a number of predefined plots. Zero means that none
of the plots are produced, while increasing values (e.g. 1 or 2) increases
the number of plots produced. If the plotting fails a warning is produced,
and the recipe continues. The default behaviour of the plotting is to use
gnuplot (with option -persist). The recipe currently produces 1D-plots
using gnuplot commands. The recipe user can control the actual
plotting-command used by the recipe to create the plot by setting the
environment variable CPL_PLOTTER. Currently, if CPL_PLOTTER is set it must
contain the string ´gnuplot´. Setting it to ´cat >
my_gnuplot_$$.txt´ causes a number of ASCII-files to be created,
which each produce a plot when given as standard input to gnuplot (e.g.
later or on a different computer). 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) and then setting CPL_PLOTTER to my_gnuplot.pl. The
predefined plots include plotting of images. Images can be plotted not
only with gnuplot, but also using the pnm format. This is controlled with
the environment variable CPL_IMAGER. If CPL_IMAGER is set to a string that
does not contain the word gnuplot, the recipe will generate the plot in
pnm format. E.g. setting CPL_IMAGER to ´display - &´
will produce a gray-scale image using the image viewer display. (int;
default: 0). The full name of this option for the EsoRex configuration
file is visir.visir_old_spc_wcal.plot [default = 0].
- --slit_skew
<float>
- Distortion correction: Skew of slit (degrees) (clockwise) (float; default:
0.52). The full name of this option for the EsoRex configuration file is
visir.visir_old_spc_wcal.phi [default = 0.52].
- --spectrum_skew
<float>
- Distortion correction: LMR Skew of spectrum (degrees) (counter-
clockwise). Not used in High Resolution (float; default: 1.73). The full
name of this option for the EsoRex configuration file is
visir.visir_old_spc_wcal.ksi [default = 1.73].
- --vert_arc
<float>
- Distortion correction: LR Detector vertical curvature (pixel). Reduced by
a factor 4 in MR. Not used in HR A-side. Increased by a factor 115/52 in
HR B-side (float; default: -0.8). The full name of this option for the
EsoRex configuration file is visir.visir_old_spc_wcal.eps [default
= -0.8].
- --hori_arc
<float>
- Distortion correction: LMR Detector horizontal curvature (pixel).
Increased by a factor 1.5 in HR A-side. Reduced by a factor 2 in HR B-side
(float; default: 0.0). The full name of this option for the EsoRex
configuration file is visir.visir_old_spc_wcal.delta [default =
0.0].
- --rl
<int>
- Reject leftmost columns in spectrum extraction, zero means all columns on
the left are used. In cross-dispersion mode a (small) negative number may
be used (pixel) (int; default: 0). The full name of this option for the
EsoRex configuration file is visir.visir_old_spc_wcal.reject_left
[default = 0].
- --rr
<int>
- Reject rightmost columns in spectrum extraction, zero means all columns on
the right are used. In cross-dispersion mode a (small) negative number may
be used (pixel) (int; default: 0). The full name of this option for the
EsoRex configuration file is visir.visir_old_spc_wcal.reject_right
[default = 0].
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.
