Hi
After the power dip on sub=nday evening the response of inner sector 3 and 4 has gotten excessive noise.
The attached plots shows #RDO bytes before and after i.e. 82040 -power dip- 28044
and high noise in the inner sectors . particular 3 with the broad timebin peak in middle looks crazy.
It still looks like this in in all runs since the power dip.

pedestals were taken after powerdip.

By the way run044 had fewer events because the run was 100% dead after 10 min. but only discovered after 30 min.
