Detailed Description

Monte Carlo truth information used for tracking validation.

Object with references to the original SimTrack and parent and daughter TrackingVertices. Simulation with high (~100) pileup was taking too much memory so the class was slimmed down and copies of the SimHits were removed.

Author: original author unknown, re-engineering and slimming by Subir Sarkar (subir.nosp@m..sar.nosp@m.kar@c.nosp@m.ern..nosp@m.ch), some tweaking and documentation by Mark Grimes (mark..nosp@m.grim.nosp@m.es@br.nosp@m.isto.nosp@m.l.ac..nosp@m.uk).

Constructor & Destructor Documentation

TrackingParticle::TrackingParticle ( )

Default constructor. Note that the object will be useless until it is provided with a SimTrack and parent TrackingVertex.

Most of the methods assume there is a SimTrack and parent TrackingVertex set, so will either crash or give undefined results if this isn't true. This constructor should only be used to create a placeholder until setParentVertex() and addG4Track() can be called.
