Diphotons yield in Data:

3 types of difference to understand

data/MC

data/data between groups

data/data between Run2010A and Run2010B (trigger paths)

Susan(Lyon) - comparison with my ~3pb-1 spectrum. This was my older pT 20,20 spectrum, and theirs was pT 30,30

Duong(Exo ADD model) - This is not the spectrum from our RS group. His backgrounds are not MC (attempt at data estimated rates). I would compare with this last.

Yousi/Toyoko(RS group) - Here there is data excess compared to MC, but the QCD sample is regular, and not the EM-enriched (I'm adding this soon as the xfer finishes). The Data yield also seems different from MPA (yousi - QCD group). We are comparing event by event.

Ntuples are made and maintained by yousi on castor

Yousi(QCD/Higgs group) - using /EG/Run2010A-SepReRECO for Run2010A (2.3 of 3.1 pb-1 returned) and /Photon/Run2010B-promptreco for Run2010B (1.337+2.5pb-1 + 3.9pb coming v. soon). ntuples private to our t3-higgs:/raid1 (yousi is a developer of MPAnalyzer, but 38X is not official yet).

HLT triggers:

run2010A: HLT_Photon15_L1R || HLT_Photon15_Cleaned_L1R || HLT_Photon20_L1R || HLT_Photon20_L1R || HLT_Photon20_Cleaned_L1R || HLT_Photon30_L1R || HLT_Photon30_L1R_8E29

run2010B: HLT_Photon30_Cleaned_L1R || HLT_Photon50_L1R || HLT_Photon50_Cleaned_L1R

run2010B also has the double triggers available, but didn't use these yet.
