keyword=re: u10, d10I think u10 and d10 may be ok on L-HRS. It's worth re-looking.
For example, run 3781 was 47.4 minutes long, and in that time
the x10 gain may overflow (it has the highest rate among the
3 gain settings) leading to a sign bit issue. See fig 1.
First two plots show the counts on u10 and d10 on L-HRS versus
time. Near the end of the run it appears negative. Next I show
how the d10 counts correlate with d1. Finally I show the u10
rate versus time before 2500 sec. It shows the beam trips and
looks normal.
