In this section the different selections used in ND280 are explained

Inclusive numuCC selection in the tracker

#cut	cut class	defined in file	Cut description
1	EventQualityCut::Apply	baseSelection.cxx	Event quality: good detector and beam quality flags
2	TotalMultiplicityCut::Apply	numuCCSelection.cxx	Total multiplicity cut: at least one track with TPC segments
3	FindLeadingTracksAction::Apply, FindVertexAction::Apply, TrackQualityFiducialCut::Apply	numuCCSelection.cxx	Select muon candidate as the highest momentum negative (HMN) track with more than 18 clusters in the TPC and initial position in the FGD FV
4	ExternalVetoCut::Apply	numuCCSelection.cxx	External veto cut
5	ExternalFGD1lastlayersCut::Apply	numuCCSelection.cxx	External FGD1 last layers cut
6	MuonPIDCut::Apply	numuCCSelection.cxx	Muon PID cut

numuCC selection with multiple pions in the tracker

This selection adds tree branches on top of the numuCCSelection. As descrived in numuCCMultiPiSelection::DefineSteps "numuCCMultiPiSelection::DefineSteps "the cuts of the numuCCSelection are copied to this selection. Then new cuts for each branch are added:Cuts for Branch 0: This is the branch requiring no pions

#cut	cut class	from source file	Cut description
6	ExternalVetoCut::Apply	numuCCSelection.cxx	External veto cut
7	ExternalFGD1lastlayersCut::Apply	numuCCSelection.cxx	External FGD1 last layers cut

Cuts for Branch 1: This is the branch requiring 1 and only 1 pion

#cut	cut class	from source file	Cut description
