Procedure:

  • generate 1 GeV η's which decay generically in the GlueX detector
  • reconstruct η→γγ and π0→γγ
    • π0 produced in η decay have low momentum
    • very few additional "clean-up" cuts applied
  • kinematically fit η's and π0's and examine confidence level distributions and pull distributions.
    • tests the accuracy of the photon covariance matrix
