keyword=Changes made in T7.CI ignored that the t5/t7 overlapped events are much fewer than t7 events, as ole said, that's why my previous t7 efficiency calculation is depending on ps5 so much.
Now I am selecting events just from t5 trigger, which means
eff. = (T5&T7&PID)/(T5&PID)
I also inculded the method from xiaochao,
eff. = (T7&PID)/(T5&PID*ps5)
which will be plotted in the bottom pad.
Comparing the results using runs with different prescales,
1360, ps5=4; 1347, ps5=1
I think (T5&T7&PID)/(T5&PID) may be a more stable way
