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):
- eemc-cvs: EEMC only with geometry file from CVS (cAir-fixed)
- full-cvs: Full STAR with geometry file from CVS (cAir-fixed)
- eemc-j-noL: EEMC only with Jason geometry file (disabled 3-new SMD layers)
- full-j-noL: Full STAR with Jason geometry file (disabled 3-new SMD layers)
