    v9 v10  
    5656      * isolation criterion: sum PT of tracks in a cone around the muon (the muon track is subtracted) of size = min(10 GeV/PT,0.3) < 6% muon PT.
    5757 
    58 *   common to electron and muon:
     58*   jet:
     59      * clustering: anti-kT with =0.4
     60      * pT > 25 GeV
     61      * |eta|<2.5
     62      * Pile-up rejection: jets with pT < 60 GeV and |η| < 2.4 are required to satisfy pile-up rejection criteria (JVT)
    5963
    60       *
     64*   b-jet: MV2c20 algorithm. In simulation, the tagging algorithm gives a rejection factor of about 130 against light-quark and gluon jets, and about 4.5 against jets containing charm quarks.
     65   
     66*   preventing double-counting:
     67      * the closest jet within DR=0.2 cone of an electron is removed.
     68      * if, after the previous selection cut, the nearest jet of an electron is in DR=0.4 cone, then the electron is removed.
     69      * muons in a DR=0.4 cone around a given jet are removed. BUT if the jet has fewer than three associated tracks, the muon is kept.
