No problem observed. See first image below (test_corel_Pulesr_all.png)
Didn't work properly with a tac signal divided in 3 or from 3 tacs with same start /stop. See test_corel.png and test_corel_2000.png
This might be due to the time calibrator trigger as it is very random and pile-up effects can contribute. Maybe with a very low trigger rate might work |
- The tac plot look convincing to me, the diagonal peaks seems to hold almost all the stat.
- On the other hand I found it difficult to conclude from the pulser one, seems all event hold the same value, any miscorrelation in the merger would lead to the same plot.
