2009.10.27: Jason EEMC geometry: comparison without LOW_EM option

Monte-Carlo setup:

• One photon per event
• Disabled new SMD layers (EXPS EBLS EFLS) in Jason geometry
• EEMC only and Full STAR geometry configurations without 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-noL: EEMC only with Jason geometry file (disabled 3-new SMD layers)
4. full-j-noL: Full STAR with Jason geometry file (disabled 3-new SMD layers)
