Interpreting the output of gemc/evio2root
Coordinates: From Maurizio, "the "root" coordinate system has (0,0,0) as the center of the target, the z-axis along the beam, and the y-axis pointing up." Theta and phi "are the normal theta and phi definition of a 3-vector in a coordinate system: Theta is the angle with the z-axis. Phi is the azimuthal angle."

E - Total energy of the particle? Edep - Energy deposited by the particle. evn - layer - Layer of the SVT hit. lx, ly, lz - Local coordinates of the hit (mm) mpid - Mother particle ID. mvx, mvy, mvz - Vertex of the mother particle. nbsthit - Maurizio says: "The number of hits in the barrel part of the SVT" Needs clarification. pid - Particle ID (that is, its type). sector - Which magnet they are under. strip - t - vx, vy, vz - Vertex of the primary particle. x, y, z - Global coordinates of the hit (mm).
