Description

Robert Sulej is pointing out that a simple way to fetch the already reconstructed end point of a track is necessary.
The suggested requirements are:
  • needs to be available using recob::PFParticle
  • needs to be available using recob::Track

recob::PFParticle already has recob::Vertex vertices associated with the particle (not the track that is associated to the particle).
Currently it's possible for a decaying particle to determine its end vertex by picking any of the daughter particles and get its origin vertex.
This approach fails for stopping and exiting particles, or in general for any particle without daughters. There is also a issue specific to pandora in this approach.

For recob::Track there is no associated recob::Vertex, although it may be enough to pick the last trajectory point instead.
