keyword=scaler checks, inclu deadtimeThis is a detailed check of scalers recorded in the datastream
for run 2036. They look fine. See rates from triggers, BCM,
and other things (fig 1). The deadtime is computed differentially
and assumes that every T6 is also a T3. This gives 14% deadtime
(bottom, right panel) with fluctuations of about 1 or 2%.
The result agrees with the deadtime displayed in the end-of-run
entry for run 2036.
So far, all is well in scaler land.
