Too many silicon hits #68

Closed padsley closed 9 years ago

padsley commented 9 years ago

I'm currently looking at run 37 and have far too many silicon hits passing the gate conditions on things. Can have up to 2000 but there seems to be a peak at around 20.

This is possibly related to that silly thing where the loop over the backs wasn't checking the events properly. Nic mentioned something about this. I don't know if this is included in the current version of SetupDev.

I'm going to check and then hopefully that will deal with the problem.

I think the problem is because the code is still trying to loop over the back TDC entries and so it's filling the SiliconData class with repetitions of the same event.

Need to suppress the loop over back TDC values when they're not in use.

Fixed!

The problem was the lack of pedestal for the ADC values which meant that they passed every event.

I've not seen that behaviour before so it's something worth keeping an eye on.

I'm not going to push these changes to the repo but I'll just keep them on arthur for now until we can work out what's happening later.
