NAME

       visir_old_spc_wcal - Old DRS detector: Spectroscopic wavelength calibration recipe

SYNOPSIS

       esorex visir_old_spc_wcal [OPTIONS] FILE.sof

DESCRIPTION

       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.

OPTIONS

       --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.
