Description

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.

I can imagine a few ways of doing this.
Either

  • store the spill & event numbers in each of the structures, eg. in SciFiTracks, TOFSpacePoints, EMRBarHit, etc
    or
  • store them in the ReconEvent structure
    or
  • store them in a separate common class
