all reconstructed calorimeter hits - those that are associated to layer clusters have rechit_cluster2d >= 0, which is the index of the cluster2d in the ntuple. HFNose and HF rechit are not associated to layer clusters.
calopart mix:MergedCaloTruth std::vector<CaloParticle> Every CaloParticle is linked to the first stable particle originating from the cascade of particles that left hits in the calorimeters. This stable particle is not included as a SimCluster (unless it itself left hits in the calorimeters).
