|---|---|---|---|
| event/run/lumi | - | - | general event info |
| vtx | g4SimHits |
std::vector<SimVertex> |
primary vertex position |
| genpart | g4SimHits |
std::vector<SimTrack> |
truth level tracks/particles and information related to their extrapolation towards HGCAL. In particular reachedEE==2 indicates that the particles reached HGCAL while reachedEE==1 is for barrel calorimeter and reachedEE==0 is for the other cases |
| simcluster | mix:MergedCaloTruth |
std::vector<SimCluster> |
Geant particle and its associated hits (DetIds) in the HGCal |
| pfcluster | particleFlowClusterHGCal |
std::vector<reco::PFCluster> |
mapping of the SimCluster DetIds to the reconstructed hits |
| cluster2d | hgcalLayerClusters |
reco::CaloClusterCollection |
reconstructed layer (2D) clusters - those that are associated to a multicluster have cluster2d_multicluster >= 0, which is the index of the multiclus in the ntuple |
| multiclus | hgcalLayerClusters |
reco::HGCalMultiCluster |
reconstructed multi-cluster (3D) built from layer clusters |
| rechit | HGCalRecHit::HGCEERecHits HGCalRecHit::HGCHEFRecHits HGCalRecHit::HGCHEBRecHits |
HGCRecHitCollection |
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 |
| 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). |
| track | generalTracks |
std::vector<reco::Track> |
tracks passing highPurity selection |
| gunparticle | offlinePrimaryVertices |
reco::Vertex |
id, energy, pt, eta and phi of gun particles associated to their corresponding vertex |
