0001 Storage of hits in Track objects
0002 ================================
0003
0004 struct HitOnTrack
0005 {
0006 int index : 24;
0007 int layer : 8;
0008
0009 HitOnTrack() : index(-1), layer (-1) {}
0010 HitOnTrack(int i, int l) : index( i), layer ( l) {}
0011 };
0012
0013 index - index of hit withint the layer it belongs to;
0014 layer - mapped from CMSSW detector/layer as described below.

0017 CMSSW -> TrackerInfo layer numbering
0018 ====================================
0019
0020 CMSSW uses detector (1 - 6) / layer numbering, our code uses a single layer
0021 index.
0022
0023 stereo = simhit_detId & 3; 0 - single layer, 1 - stereo, 2 - dual layer
