Monte-Carlo setup:

• Throwing one photon per event
• Full STAR y2006h (latest EEMC-v6.2 and BEMC with LOW_EM cuts, rest of geometry from CVS)
• Throw particles flat in eta (1.08, 2.0), phi (0, 2pi), and energy (5-35 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

Results: Update for the previous tests of EMC v6.2 geometry after fixing TPC/EEMC overlap

Figure 1: Endcap EMC sampling fraction: total calorimeter energy, pre1-, pre2-, post- shower layers, and SMD-u energy
Red: (previous) ecalgeo-v6.1 with global LOW_EM option
(Note: same points as in this post, Fig. 1 lower left, label y6:LOW_EM)
Black: (new) ecalgeo-v6.2 (embedded LOW_EM cuts), no global LOW_EM option

Figure 2: Pre-shower migrations
Change in TPC geometry seems to introduce a reasonable (small) change in pre-shower migration
