Detailed Description

User stepping action used to filter events where the primary particle falls below a threshold before reaching the CalorimeterRegion.

This is a simplistic filter designed similar to the TaggerVetoFilter.

◆ stepping()

void biasing::PrimaryToEcalFilter::stepping ( const G4Step * step )

overridevirtual

Only process if the track is a primary (parentID == 0) and if the event is not aborted and the particle is not in the CalorimeterRegion.

If the energy of the particle is below the input threshold, then the event is aborted.

Parameters
