keyword=BB Cerenkov modifications to PMT 5 and PMT 17 signals
The signal for PMT 5 was moved to a different amplifier channel to see if
it addressed the pedestal noise noted in Halog
256146. This seemed to fix the similar, earlier problem with PMTs 2, 3.
The missing TDC signal for PMT 7 should be solved. The patch cables for
PMTs 7 and 17 were flip-flopped at the upper patch panel (they are
adjacent). PMT17 is dead so no signal there. On the upside, the signal
for PMT7 should have been recorded in the PMT17's TDC channel.
