Function Documentation

unsigned int remid::HighestPIDTrack	(	const std::vector< art::Ptr< rb::Track > > &	sliceTracks,
		const std::string &	remidModuleLabel,
		const art::Event &	e
	)

Function which finds index of the best ReMId track among a vector of tracks. Requires the event to fetch associated ReMId objects and the module label
