  • Reconstructed Z minus generated Z over the length of the module. The deviations are less than 0.5 cm.

  • Reconstructed photon energy BEFORE corrections

  • Unconstrained invariant mass (left) and fit confidence level (right) for pi0 candidates after the mass-constrained kinematic fit. Candidates with Chi2 < 3(5) are shown in red (blue). This can be compared with Figure 5.12 in

  • Unconstrained invariant mass (left) and fit confidence level (right) for eta candidates after the mass-constrained kinematic fit. Candidates with Chi2 < 3(5) are shown in red (blue). This can be compared with Figure 5.13 in
