This data set (I think) was called to my attention multiple ways and
has caused me to make a modification to FILLM.  The on-line channel 0
summed to exactly zero due to correlator error or severe interference
(channels alternate + and - the same value) causing the channel 0 data
set to have fewer samples than the line data set.

I am unfamiliar with UVPRM and just looked at it.  Despite what the
help file (does not) say, all values in BPARM are significant.
BPARM(2) controls what is plotted on the Y axis.  The message says
that the max and min values in the selected data for that type of plot
are equal.

I suspect that there is a lot of editing that will have to be done on
these data.
