0001 // Common tool for pileup subtraction. Can be used
0002 // to subtract pileup as a 4-vector or just to scale
0003 // the jet 4-vector so that its Pt becomes less by
0004 // the amount of pileup Pt.
0005 //
0006 // If the amount of pileup is larger than the amount
0007 // of Pt available in the jet, all components of the
0008 // jet 4-vector will be set to 0.
