// Imlementation of a filler to fill HepMC particles or the AOD GenParticle candidates (gen)
|
| 7 |
// and SimTracks (sim) with association map to TrackingParticles (for hit-based MC truth matching)
|
| 8 |
// into mithep::MCParticles. Generated and simulated particle information is thus merged into a
|
| 9 |
// single collection.
