Function Documentation

Measurement ActsExamples::EDM4hepUtil::readMeasurement ( const edm4hep::TrackerHitPlane &  from,
const edm4hep::TrackerHitCollection *  fromClusters,
Cluster *  toCluster,
const MapGeometryIdFrom &  geometryMapper 
)

Reads a measurement cluster from EDM4hep.

Inpersistent information:

  • hit index
  • 1D local coords?
  • segment path

Known issues:

  • cluster channels are read from inappropriate fields
  • local 2D coordinates and time are read from position
