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.
