Monte-Carlo configuration

  • Single photon in the EEMC (flat in eta, pt, phi)
  • Narrow vertex distribution with sigma=1cm
  • 10 muons thrown in Barrel (|eta|<0.5) to reconstruct vertex
  • 3 muons thrown in each BBC (|eta|~4) to fire the trigger
  • Run 6 L2e-gamma-trigger id = 137641
  • STAR geometry tag: y2006h
  • Photon cuts:
    1.1 < eta < 1.95
    3 < pt < 15 GeV
    0 < phi < 2pi
