Invariant Masses
- High mass tails due to incorrect photon reconstruction have been removed. These tails were due to photons in the FCAL being reconstructed with vertex-z = 0, such that they had bogus momentum vectors. This was fixed when Miha Kornicer recently updated the photon reconstruction code.
- Pi0 invariant mass:
- X(2000) invariant mass:
