These data (run 32488) were recorded using a filter in the event readout list, so only channels with 6 consecutive samples exceeding a threshold of 116 were recorded, provided that 5 channels had 8 consecutive samples over 124. (pedestal ~ 60, #sigma ~ 16)
Compare resolution with channels 68 (on noisy board E4) and 148 (similar position on different board E14)
Looking to see if zero-crossings are linked to hits in other channels. Zero-crossing time is the sample number when the adc content drops to 0 - pedestal is not subtracted. Pedestals are set to approx 60, with pedestal width ~ 16.
