I have noticed that for all of this run there are two noisy area in the iTPC.
They are clearly visible in this adc charge plot for sector 19.
I confirmed al of these channels rwo 11:1-27 row12:1-29 and row 13 1-4 corresponds to FEE#43 (60 channels)
and the rows 19: 59-82, 20: 65-86, 21 83-86 22 81-86 corresponds to 58 channels in FEE 35

They do not really show up in the cluster data for sector 19. So it is a bit of a close call if these channels should be masked out for the rest of the run.
Cerntainly these FEEs ought to be changed for next years run.

I appreciate your input to this
