0002 Package:    GeneralInterface/GenFilters/ModelpMSSMFilter

0007 Description: EDFilter which checks the event passes a baseline selection for the run-II pMSSM effort.
0008 
0009 Implementation: 
0010 
0011 The following input parameters are used 
0012   gpssrc = cms.InputTag("X") : gen particle collection label as input
0013   jetsrc  = cms.InputTag("X") : genjet collection collection label as input
0014   jetPtCut = cms.double(#) : GenJet pT cut for HT
0015   jetEtaCut = cms.double(#) : GenJet eta cut for HT
0016   genHTcut = cms.double(#) : GenHT cut
0017   muPtCut = cms.double(#) : muon pT cut
0018   muEtaCut = cms.double(#) : muon eta cut
0019   elPtCut = cms.double(#) : electron pT cut
0020   elEtaCut = cms.double(#) : electron eta cut
0021   gammaPtCut = cms.double(#) : photon pT cut
0022   gammaEtaCut = cms.double(#) : photon eta cut
0023   loosemuPtCut = cms.double(#) : loose muon pT cut
0024   looseelPtCut = cms.double(#) : loose electron pT cut
0025   loosegammaPtCut = cms.double(#) : loose photon pT cut
0026   veryloosegammaPtCut = cms.double(#) : even looser photon pT cut
