# 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):

**eemc-cvs**: EEMC only with geometry file from CVS (cAir-fixed)
**full-cvs**: Full STAR with geometry file from CVS (cAir-fixed)
**eemc-j**: EEMC only with Jason geometry file
**full-j**: Full STAR with Jason geometry file
