hello, // ... generate your signal on the fly PndEvtGenDirect *EvtGen = new PndEvtGenDirect("pbarpSystem","pipi.dec",4.0); EvtGen->SetStoreTree(kFALSE); primGen->AddGenerator(EvtGen); // Create and Set Magnetic Field //------------------------------- fRun->SetBeamMom(4.0) where from we get 4.0??
If you check the standard macro/run/sim_complete.C you can see that SetBeamMom is the momentum of the projectile antiproton.
