Comparison of Generated and Reconstructed Tracks
- NOTE: There was no observed φ-dependence on track reconstruction distributions.
γ's
- p vs θ distributions for the generated & reconstructed photons:
π+'s
- p vs θ distributions for the generated & reconstructed π+'s:
π-'s
- p vs θ distributions for the generated & reconstructed π-'s:
p's
- p vs θ distributions for the generated & reconstructed protons:
