keyword=About the run
Actually, before this run, I observed that the online dead time sometimes
goes to -15% for a couple minutes, one day before the problem (IT goes to
-15% all the time).
Thus, I think this could be affected the previous data partly. We need to
have a close look.
Bob pointed out that this could affected all the possible TDC ADCs on the
LEFT. We need to keep in mind this is the case.
The good thing is that it fixed almost all our problems. :)
