.TH VISIR_OLD_SPC_WCAL "7" "4.3.10" "visir_old_spc_wcal" "visir recipes" .SH NAME visir_old_spc_wcal \- Old DRS detector: Spectroscopic wavelength calibration recipe .SH SYNOPSIS esorex .B visir_old_spc_wcal [OPTIONS] FILE.sof .SH DESCRIPTION This recipe estimates the dispersion relation using the atmospheric spectrum in a long\-slit spectroscopy half\-cycle frame. .PP 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. .SH OPTIONS .TP \fB\-\-auto_bpm\fR \fI\fR Automatic detection and correction of bad pixels (bool; default: True). The full name of this option for the EsoRex configuration file is \fBvisir.visir_old_spc_wcal.auto_bpm\fR [default = \fITrue\fR]. .TP \fB\-\-plot\fR \fI\fR 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 \fBvisir.visir_old_spc_wcal.plot\fR [default = \fI0\fR]. .TP \fB\-\-slit_skew\fR \fI\fR Distortion correction: Skew of slit (degrees) (clockwise) (float; default: 0.52). The full name of this option for the EsoRex configuration file is \fBvisir.visir_old_spc_wcal.phi\fR [default = \fI0.52\fR]. .TP \fB\-\-spectrum_skew\fR \fI\fR 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 \fBvisir.visir_old_spc_wcal.ksi\fR [default = \fI1.73\fR]. .TP \fB\-\-vert_arc\fR \fI\fR 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 \fBvisir.visir_old_spc_wcal.eps\fR [default = \fI\-0.8\fR]. .TP \fB\-\-hori_arc\fR \fI\fR 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 \fBvisir.visir_old_spc_wcal.delta\fR [default = \fI0.0\fR]. .TP \fB\-\-rl\fR \fI\fR 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 \fBvisir.visir_old_spc_wcal.reject_left\fR [default = \fI0\fR]. .TP \fB\-\-rr\fR \fI\fR 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 \fBvisir.visir_old_spc_wcal.reject_right\fR [default = \fI0\fR]. .PP Note that it is possible to create a configuration file containing these options, along with suitable default values.
