       naco_spc_combine - Combination of spectroscopic science data


       esorex naco_spc_combine [OPTIONS] FILE.sof


       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


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

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

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

       --plot <long>
              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., that  executes  gnuplot  after  setting  the
              desired  gnuplot  options  (e.g.  set  terminal  pslatex  color)  and  then setting
              CPL_PLOTTER to 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. (long; default: 0). The full name of this
              option for the EsoRex configuration file is naco.naco_spc_combine.plot  [default  =

       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'
