in recoilNtp.cc you find
if (isRecKaon(i)) {
vubDepleted = kTRUE;
fNKaon++;
mk4Vector(p4t, momentumTrk[i], thetaTrk[i], phiTrk[i], KAPMASS);
}
and in recoilNtp.hh
inline Bool_t recoilNtp::isRecKaon(Int_t i) {return
(TMath::Abs(kaonIdTrk[i]) & IDKA);}
where IDKA is 8 right now (in b0cuts..dat) but I actually used 16.
