SimHits, SimTracks, and SimVertices in FastSim

SimHits in tracker

• objects of class PSimHit (link to code)

Useful variables

• int PSimHit::trackId() returns index of SimTrack in SimTrackCollection that produced the SimHit
• int PSimHit::particleType() returns the Pdg id number of the SimTrack that produced the SimHit
• float PSimHit::energyLoss() returns the energy lost by the SimTrack through ionisation in the silicon module at which the hit resides. This variable is used, during digitization, to determine the strength of the signal in the silicon sensors.
