Summary of SiD Tracking Discussions, May 7-11, 2007 at SLAC

Persistency

  • We will only persist the official LCIO objects: SimTrackerHit, RawTrackerHit, TrackerHit and the reconstructed track class ( don't know its proper name).
  • We will work with LCIO to get small changes made to these objects, but not big changes. We will shoehorn our objects into the defined persistent objects.
  • We will not support persistency for other information even if it cannot easily be recomputed.
  • We will not persist clusters.
  • We anticipate that a future evolution of the reconstructed track class ( perhaps it will be
    spelled trajectory, not track ), will allow us to persist residuals.

I view this as too confining. We should be able to persist anything we put into the event, even if that information
is not useful to the other collaborations.
