Hi Justin,

This is really great and wonderful to see, you must present this at the collaboration meeting next week.

The slides linked below show the cuts used to select exclusive p+rho and p+pi0 final states in the data from that run.  The observed azimuthal distributions for events from the coherent peak region show significant asymmetries for both the p+rho and p+pi0 final states which are expected for the linearly polarization photon beam.
