Member Function Documentation

AddTrack() [1/2]

void AddTrack	(	float	px,
		float	py,
		float	pz,
		float	e,
		float	charge,
		SIMPLEPID	pid
	)

Add the track to the event.

Parameters

px	- x component of the particle momentum
py	- y component of the particle momentum
pz	- z component of the particle momentum
e	- energy of the particle
charge	- unit charge of the particle
pid	- particle identity - hypothesis with the highest maximum likelihood

Definition at line 34 of file BEvent.cc.

{
  new ((*m_particles)[m_nprt++]) BParticle(px, py, pz, e, charge, pid);
}

AddTrack() [2/2]

void AddTrack	(	float	px,
