One more thing:
- at first sight, about 60% of the TOF PMTs are already in the
neighborhood of ADC channel 1650 (between 1450 and 1800 - the
differences are surely due to low statistics and different pedestals),
with only 20% above ADC channel 2000. These are probably due to new tubes,
fixes to problems we had (different optical connections) and maybe a few
mistakes we made when recording the DTF voltages?
Only a couple of tubes (RTOF 15, top and bottom) were very high indeed,
timing may need more serious adjustment for those. Note that those
positions were used for the start counter, maybe the voltages got changed
more than needed in the process...
