NAME

       naco_spc_combine - Combination of spectroscopic science data

SYNOPSIS

       esorex naco_spc_combine [OPTIONS] FILE.sof

DESCRIPTION

       naco_spc_combine -- NACO Combination of spectroscopic science data.

       The  files  listed  in  the  Set  Of Frames (sof-file) must be tagged: NACO-raw-file.fits SPEC_NODDING or
       NACO-flat-file.fits MASTER_SPC_FLAT (optional).

       For nodded frames (SPEC_NODDING) there must be an identical number of  exposures  on  each  side  of  the
       center,  these pairs of nodded exposures should preferably be taken with one immediately after the other.
       More precisely, the i´th A-FRAME will be paired with the i´th B-frame

OPTIONS

       --xtmax <int>
              Stop the spectrum extraction at this column (int; default: 1024). The full name of this option for
              the EsoRex configuration file is naco.naco_spc_combine.extract_max [default = 1024].

       --xtmin <int>
              Start  the  spectrum extraction at this column (int; default: 1). The full name of this option for
              the EsoRex configuration file is naco.naco_spc_combine.extract_min [default = 1].

       --save <int>
              A positive value causes additional, intermediate products to be saved (int; default: 0). The  full
              name of this option for the EsoRex configuration file is naco.naco_spc_combine.save [default = 0].

       --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 naco.naco_spc_combine.plot [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.
