Target Event

Coordinate origin : The center of the platinum target.
(x,y,z) = (-ZZ,YY,XX) : Position of the particle.
(px,py,pz) = (-PZ,PY,PX) : Unit vector of the momentum direction.
PP : Magnitude of the momentum.
EE : Kinetic energy.

PN : Particle ID of the GEANT definition (1=gamma, 10=KL, 13=n, 14=p,...).
