Want event and spill number in detector structures
When looking at detector hits -- e.g. SciFi tracks, spacepoints -- there is no way to know the trigger number (particle event number) or spill number (physics event number). This makes it difficult to identify events, and to accurately correlate objects between different detectors.
The only way then to get the event number is to have a counter in the loop. This is not robust. It also makes it diffi
I'd like to request that we store the PhysEventNumber and ParticleEventNumber in higher level reconstructed structures.
