T3 rate is only 70 Hz on scaler screen (r-arm measurement).
However there are lots of double hits in T3. see figure 1.
.
scalers are all counting at reasonable rates. nobody is counting more
than 1 kHz. conclusion must be that either there is something
flaky in the trigger (do we get number of hits from MLU output?)
or that for some reason there is a correlation between paddles
for real S1.S2 coincidences. Former explanation seems more
plausible.
.
For comparison see the plots for T1/T5 (fig. 2). T1 is counting
almost ten times faster, yet looks cleaner.
