In the standard eRHIC Monte Carlo format, the scattered lepton beam is assumed to be the first final-state particle in the particle list with the same PDG code as the incident lepton beam.

Please overwrite this method accordingly! By default, it will simply use the fourth particle in the particle list. See e.g. EventPythia, EventSimple.
