Photon+jet z-vertex distributions

(1)Dijets from the jet trees with an associated gamma to one of the jets from the gamma  trees (ConeJets5 branch is used in this study)

(2) Photon and jet are back to back i.e  [cos(Φγ – Φjet)]<-0.8

(3) Detector eta of the away side jet : ΙηjetΙ < 0.8

(4) Detector eta of photon candidate : 1.08<η<2.0

(5) pT of photon > 7 GeV

(6) pT of away side jet > 5 GeV
