Member Typedef Documentation

typedef TrackingRecHit::Type BeamSpotTransientTrackingRecHit::Type

Type of hits: valid = valid hit missing = detector is good, but no rec hit found inactive = detector is off, so there was no hope bad = there were many bad strips within the ellipse (in Tracker) = hit is compatible with the trajectory, but chi2 is too large (in Muon System)

Reimplemented from TrackingRecHit.
