LAC distribution (not corrected for ped drift) in ADC and pedestal drift for LEX8 channel obtained with calibGenCal code
Update on LAC threshold
I used genSciLacHists and fitLacHists to make the following plot
LAC distribution corrected for pedestal drift
3 channel avec a LAC value above 85 ADC.

The corresponding histograms are here :
for T7L2C3F1, the LAC value is probably wrong.
the other histograms have not enough statistic to make a conclusion.
Using genLacHists T1L1C1F1 and T7L2C3F1 show are questionable. here are the plot
NB: the lacMeV values are very strange for all channel. any idea?

Hot channels
A few channels along the central AFEE path (columns 5 and 6) show the readout noise.
