Description

The new track proxy has to be able to get to the original unfitted TrackTrajectory.
This is a key component so that the physics analyzer can choose the best features from the fitted or unfitted trajectory.

To my knowledge, the relation between a recob::Track and its original recob::TrackTrajectory is described via art associations, where:
  • a recob::Track collection may or may not have such associations
  • if the association is present, each recob::Track is associated to a recob::TrackTrajectory
  • a recob::TrackTrajectory can be not associated to any recob::Track (in the case a fit failed)

Can we rely on the associations to be ordered on both sides? or at least on recob::Track side?

On the track side. (if the input is PFParticles the TrackTrajectory sorting is not preserved)
