Parameters valid in both TIME mode and SPECTRAL mode:
AMPLITUDE, PHASE, REAL, or IMAGINARY: referring to the visi-
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-
AUTOCORR. : the autocorrelation power measured in the sub-
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.

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

The available parameters are the same as with the SET Y command. De-
fault is SET Y AMPLITUDE PHASE.
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).
