USER: Switch to a raw tree file based on E-theta-phi (instead of E-Px-Py-Pz) is now complete. This move was required as the momentum components will only be accurate post particle identification. A new GetVector routine was written which takes E, theta, phi and the reconstructed mass and produces a 4vector. Px, Py, and Pz are stored in the output tree along with the E, theta, phi, and M.
