          [SMOOTH Nsmooth] [/BROWSE [Ataper]] [/FILE UvData.uvt [Drop]]

        A fast previewer to figure out if there is signal and what is its  spec-
        tral  shape.  The command attempts to find out the line free regions and
        to estimate a continuum region.

        The output of UV_PREVIEW can be used  for  further  processing  commands
        (UV_BASELINE and UV_FILTER, UV_SPLIT, SPECIFY, etc...)

        If  a  catalog  is defined (see HELP CATALOG), it will also display line
        identification (red for detected ones, blue for the others).

          The behaviour is controlled by 4 parameters than can  be  set  through
        the "KEY Value" optional argument pairs. These are
          TAPER   Ntaper    : number of scale sizes  (default 4)
          CLIP    Threshold : Clipping level in Sigma (default 3.5)
          SMOOTH  Nsmooth   : Number of spectral smoothing (default 3)
          HISTO   Nhisto    : Size of histogram
        These  values  are "sticky": they remain valid until further change, and
        they can be listed by
            UV_PREVIEW ?
