# 2009.11.02 Jason EEMC geometry: results with and without LOW_EM options

Monte-Carlo setup:

- One photon per event
**Disabled SMD layers (EXPS EBLS EFLS)**in Jason geometrygeometry configurations **with and 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):
