scram b

Usage

• Objects have to fulfill the cuts described here: https://twiki.cern.ch/twiki/bin/view/CMS/TTbarHbbRun2ReferenceAnalysis
• Loose jets are defined by the same cuts as the standard ak4-jets except for the p_T-cut which is p_T > 20 GeV instead of p_T > 30 GeV. The loose jet collection is inclusive and also contains the standard jets.
• The BDTs are trained and optimized on odd-numbered Events, to avoid bias they should only be evaluated on even-numbered events (edm::Event.id().event()%2==0)
