The data are averaged in time according to the SET AVERAGING
command. It is possible to average by scan or time. In addition, this
command also controls if the data are averaged as complex numbers
(VECTOR) or if amplitude and phase are averaged separately
(SCALAR). Be cautious about the amplitude bias especially in
spectral plots where the much lower bandwidth of channels can bring
the signal to noise to low values even on calibrators (see section
2.4.2 and 2.4.3).
In addition to and after the time averaging, the data in the plot may
be averaged in bins of the x coordinates with the command SET
BINNING. It is useful to average data in spectral mode. Any
SET X command resets the binning.
