        bility  in  the  spectral window(s) or baseband(s) or  IF(s),  side-
        band(s),   baseline(s)  (or  antenna(s))  selected  by  SET SPW, SET
        mands.    Only  correlation  scans will be plotted, not autocorrela-

        band(s),   antenna(s)   selected  by  SET  SPW (or SET BB)  and  SET

        cluding calibration scans), not correlations.

    Parameters valid in SPECTRAL mode only:

      CHANNEL  :   channel  number  in the correlator (use ony  this  one if
        Fourier Transform has not been made).

      VELOCITY :  normally with respect to LSR.

        quency if the velocity is correct.

        ordinates, in the (U,V) plane, of the baseline(s) selected  by  com-
        mand SET BASELINES.

    The  available  parameters  are the same as with the SET Y command.  De-

    The /LIMITS option is used to specify fixed limits, e.g.: "SET Y  AMPLI-
    TUDE  /LIMITS a1 a2" where a1 and a2 are the amplitude limits to be used
    in this example.  The codes "*" and "=" may be used. "*" means that  the
    limits  are  automatically adjusted to the data, separately in each box;
    "=" means that common limits to all boxes are computed.

    Default limits are provided for AMPLITUDE and PHASE only: 0 * * * if SET
    PHASE  CONTINUOUS  is  effective, 0 * -180 180 if SET PHASE JUMPY DEGREE
    (with corresponding values if SET PHASE RADIANS).
