Btw, Jeson, according to /storage/TopQuarkGroup/mc/8TeV/LeptonPlus3JetsSkim/TTJets_MassiveBinDECAY_TuneZ2star_8TeV-madgraph-tauola/nTuple_v10_Summer12_DR53X-PU_S10_START53_V7C-v1_LeptonPlus3Jets/skim.log file on soolin, I think the number of processed events is wrong: the number of events passing the HBHE filter is 6844221, which is more than 6819798 stated here!
