2010.02.11 BFC and Pythia QA: Gain no-gain-spread, mean=1.05

Click here for discussion and results with spread=0.05/gain=0.95

QCD and gamma-jet data samples are described here

Resultys without gain shift can be found here
(Note: ignore parton pt=25-35GeV for the gamma-jet sample since all jobs failed)

Pythia filter configuration

StEemcGammaFilter:: running the TEST mode (accepting all events). Set mFilterMode=1 to actually reject events
StEemcGammaFilter:: mConeRadius 0.22 mSeedThreshold 2.1 mClusterThreshold 3.25 mEtaLow 0.95 mEtaHigh 2.1
StEemcGammaFilter:: mCalDepth 279.5 mMinPartEnergy 1e-05 mHadronScale 0.4 mFilterMode 0 mPrintLevel 0

BFC filter configuration

StChain:INFO - Init() : Seed energy threshold = 2.8 GeV
StChain:INFO - Init() : Cluster eT threshold = 4.2 GeV
StChain:INFO - Init() : Maximum vertex = +/- 120 cm
StChain:INFO - Init() : Running the TEST mode (accepting all events). Set mFilterMode=1 to actually reject events in BFC
