2009.10.16 Jason geometry file: Full STAR simulations

Monte-Carlo setup:

  • One photon per event
  • EEMC only and Full STAR geometry configurations with LOW_EM option
    (using Victor's geometry fix)
  • Throw particles flat in eta (1.08, 2.0), phi (0, 2pi), and pt (6-10 GeV)
  • Using A2Emaker to get reconstructed Tower/SMD energy
    (no EEMC SlowSimulator in chain)
  • Vertex z=0
  • ~50K/per particle type
  • Non-zero energy: 3 sigma above pedestal

Geometry configurations and notations (shown in the center of the plot):

  1. eemc-cvs: EEMC only with geometry file from CVS (cAir-fixed)
  2. full-cvs: Full STAR with geometry file from CVS (cAir-fixed)
  3. eemc-j: EEMC only with Jason geometry file
  4. full-j: Full STAR with Jason geometry file
