Macros to calculate the V0s efficiencies
jetConeEfficiency_Regit.C:
Run on the Ntuple:"RegitPYTHIA80_JUNE24_ppCuts_2014.root" and in this Ntuple, the HI Regit tracking was using the pp pT threshold cuts; The Jet that is using here is PFJet, and the jet pT > 60 and |eta| < 2.0; Cone size is 0.3
In order to change the InputTag of V0s from different tracking algorithm, to change the "v0analyzerNew" to "v0analyzerHI" as pp to Regit respectively.
The Ntuple is on Wei's MIT account: /export/d00/scratch/davidlw
