SET TYPE

        LAS\SET TYPE CONTINUUM or LINE or SKYDIP

    Defines on which type of data the program is working.
      - LINE (or SPECTROSCOPY) (the default when entering LAS) selects Spec-
        tral Line data only, and the program prompt is LAS>  (Line  Analysis
        System).
      -  CONTINUUM  selects  continuum  drifts results only, and the program
        prompt changes to CAS> (Continuum Analysis System).
      - SKYDIP selects only skydips, and the prompt changes to SAS>
    In CONTINUUM mode, a continuum drift is treated as a spectrum  would  be
    in  LINE  mode.  You can add drifts, subtract baseline, make gauss fits,
    change plotting scales etc... The  current  angular  units  is  used  in
    plots.  SKYDIP  mode has very limited capabiblities: only command REDUCE
    may be used to analyse the SKYDIP results.
