            band(s),   antenna(s)   selected  by  SET  SPW (or SET BB)  and  SET
            ANTENNAS commands.  Only autocorrelation scans will be plotted, (in-
            cluding calibration scans), not correlations.

        Parameters valid in SPECTRAL mode only:

        The  available  parameters  are the same as with the SET Y command.  De-
        fault is SET X TIME.

        The /LIMITS option is used to specify fixed limits, e.g.:  "SET  X  TIME
        /LIMITS  t1  t2"  where t1 and t2 are the time 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.

        For time-like plots, the defaults are "/LIMITS * *  ".   For  frequency-
        like plots, the defaults are "/LIMITS = =".
