Class Documentation¶

class RMGGeneratorFromFile : public RMGVGenerator ¶

Primary generator reading particle kinematics row-by-row from an ntuple file.

Each row of the input ntuple (LH5/HDF5/ROOT, opened through RMGAnalysisReader) specifies a Geant4 PDG id, kinetic energy, momentum direction and global time. The vertex position is supplied externally by the configured vertex generator via SetParticlePosition. The fNpart column allows several consecutive rows to be combined into a single multi-particle primary vertex.
