FYI: Alice blog on ELED block study

Monte-Carlo setup:

- One photon per event
**Disabled SMD layers (EXPS EBLS EFLS)**in Jason geometry- Put
**ELED block from CVS**file into Jason geometry 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):

**full-cvs**: Full STAR with geometry file from CVS (cAir-fixed)**full-j**: EEMC only with Jason geometry file (disabled 3-new SMD layers, ELED block replaced with that from CVS)
