Event selection

1. Official EEMC gamma filtered Monte-Carlo with Pro-pT0 tune
2. di-jets from the cone jet-finder algorithm
3. photon and jet are opposite in phi:
      cos (phi_gamma-phi_jet) < -0.8
4. pt away side jet > 5GeV
5. detector eta of the away side jet: |eta_jet_det| < 0.8
6. data : L2e-gamma triggered events
7. Monte-Carlo: emulated L2e-gamma triggered condition
8. QCD Monte-Carlo scaled to the yield in the data (MC down scaled by a factor of 1.8)
   
9. All plots with gamma pt >7GeV cut
