Description

Similarly as for clusters (issue #14265) and tracks (issue #14281), add an interface providing access to particle hierarchy information:

  • providing access to all the pre-computed information currently available (recob::PFParticle)
  • no less-than-trivial computation is performed
  • access to lower level associated objects and navigation to other particles in the flow; possibly incomplete list:
    • clusters (ideally via view::Cluster)
    • tracks (ideally via view::Track)
    • hits
    • vertices (of different categories, if supported)
    • trajectory points ("space points")
    • track seeds
    • daughter and parent particles
  • access to truth information needs to be considered both in principle and in practice

This interface object, with the candidate name of view::PFParticle, is bound to a main reconstruction action.
Additional information (for example, associated optical flashes) is not reached through this interface. This other information should be provided by a higher level abstraction (see issue #14061).

History

#1 Updated by Katherine Lato over 4 years ago

  • Status changed from New to Assigned

#2 Updated by Gianluca Petrillo over 4 years ago

  • Estimated time set to 60.00 h

The starting step should be a thorough discussion with the users.

#3 Updated by Katherine Lato over 3 years ago

  • Status changed from Assigned to Accepted
  • Assignee deleted (Gianluca Petrillo)
  • Parent task changed from #14060 to #17338

Moving this to phase 3 of the track data product work.

#4 Updated by Katherine Lato over 3 years ago

  • Subject changed from Provide an interface for access of reconstructed particle hierarchy ("particle flow") information to Design an interface for access of reconstructed particle hierarchy ("particle flow") information

#5 Updated by Katherine Lato over 3 years ago

  • Target version set to 2019-1-quarter
