Member Enumeration Documentation

EnergyVariation

enum EnergyVariation

Energy scale and smearing variations provided by EGamma. See TWiki (rev 19) and TWiki (rev 73).

Enumerator
Nominal	ecalEnergy of photon after scale & smearing corrections
ScaleUp	energy with the ecal energy scale shifted 1 sigma(stat) up
ScaleDown	energy with the ecal energy scale shifted 1 sigma(stat) down
SigmaPhiUp	energy with the ecal energy smearing value shifted 1 sigma(phi) up
SigmaPhiDown	energy with the ecal energy smearing value shifted 1 sigma(phi) down
SigmaRhoUp	energy with the ecal energy smearing value shifted 1 sigma(rho) up
SigmaRhoDown	energy with the ecal energy smearing value shifted 1 sigma(rho) down

                         {
        Nominal = 0,    
        ScaleUp,        
        ScaleDown,      
        SigmaPhiUp,     
        SigmaPhiDown,   
        SigmaRhoUp,     
        SigmaRhoDown    
    };

Identification

enum Identification

Identification flags provided by EGamma. See TWiki (rev 20) Values can be combined as a bit field, e.g. CutBasedLoose | CutBasedMedium.

Enumerator
CutBasedLoose	Loose cut-based ID.
CutBasedMedium	Medium cut-based ID.
CutBasedTight	Tight cut-based ID.
MVAWorkingPoint80	80% efficiency working point of the MVA ID
MVAWorkingPoint90	90% efficiency working point of the MVA ID
ConversionSafeElectronVeto	Electron veto.
PixelSeedVeto	Pixel seed veto.

                        {
        CutBasedLoose              = 0b0000001, 
        CutBasedMedium             = 0b0000010, 
        CutBasedTight              = 0b0000100, 
        MVAWorkingPoint80          = 0b0001000, 
        MVAWorkingPoint90          = 0b0010000, 
        ConversionSafeElectronVeto = 0b0100000, 
        PixelSeedVeto              = 0b1000000, 
    };
