keyword=Re: HAND HV change.
In the ADC channels... the most effect, from the HV change, was in the
Veto PMTs. The rest of the layers saw marginal, if no, improvement. I
speculate that the Signals are on the edge of the leading edge of the
gate. I think we can only adjust this by getting the RightHRS triggers
quicker into the Trigger Supervisor (quicker L1A to the HAND Fastbus Crate).
There was very little change to the TDC spectra, as well.
Made 20740 the golden run for the HAND analysis.
