Event selection

1. di-jets from the cone jet-finder algorithm
2. photon and jet are opposite in phi:
      cos (phi_gamma-phi_jet) < -0.8
3. pt away side jet > 5GeV
4. detector eta of the away side jet: |eta_jet_det| < 0.8
5. data : L2e-gamma triggered events
6. Monte-Carlo: emulated L2e-gamma triggered condition
7. MC scaled to 3.164^pb based on Pythia luminosity (no fudge factors)
