    keyword=Peaks in gas cerenkov

    I have been looking at the gas cerenkov on run 1129. The gas cerenkov has a nice timing peak but there are a couple of events a larger time I am not sure about. So this might hint to a timing problem or might be physics or might be just right but I cannot explain the peak at larger time. So if you have any ideas please let me know. So I plotted for channel 5 the amplitude versus time, there are a couple of big amplitude at 1270 and the main events are at 1570. Cuts on event type 3 or type 5 just change the total statistics those events are present in the same trigger type.
