Detailed Description

The TruthSegToTruthPartAssocAlg associates the TruthSegments with the primary TruthParticle from the IP.

At the same time, the truth particles are linked to all the associated segment candidates.

To perform the matching, the SDO identifiers decorated to the TruthParticle are compared with the SDO identifiers of the truth hits making up the truth segment.
