# 2009.10.26 Jason vs. CVS EEMC: removed SMD layers

Monte-Carlo setup:

- One photon per event
- Disabled new SMD layers (EXPS EBLS EFLS) in Jason geometry
**EEMC only and Full STAR** geometry configurations with LOW_EM option

Note: **LOW_EM option seems not to work for EEMC only configuration** (double checking)

(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)
