Constructor & Destructor Documentation

detsim::SimDriftElectrons::SimDriftElectrons ( fhicl::ParameterSet const & pset )

explicit

Sets the margin for recovery of charge drifted off-plane.

Parameters

margin the extent of the margin on each frame coordinate [cm]

This method sets the margin for the recovery of off-plane ionization charge. See RecoverOffPlaneDeposit() for a description of that feature.
