  1. Proton polar angle versus proton momentum for generated events (top left)
  2. Momentum distributions for generated and reconstructed protons as a function of the p generated momentum (top right)
  3. Polar angle of reconstructed protons as a function of the proton generated momentum (middle left)
  4. Chisq/Ndof for reconstructed protons (middle right)
  5. Ndof distribution (bottom left)
  6. Ndof versus proton momentum (bottom right)
