Member Function Documentation

void MuonSmear::Smear

(

TLorentzVector *

vec

)

Function to smear a generic vector.

Function to smear a generic vector. Finds the correct ets bin, gets the corresponding c1 & c2 values & then calculates the factor to scale pt by.

The input vector (vec) is then scaled with this value.

void MuonSmear::UseTopRediscoveryScaleVals

(

)

use top rediscovery values for scale

These are the values used in the top rediscovery paper for momentum scale

void MuonSmear::UseTopRediscoverySmearingVals

(

)

use top rediscovery values for smearing

These are the values used in the top rediscovery paper for momentum smearing
