[Halld-physics] Linear polarization in GlueX: Run 3185

[Justin Stevens]

Hey Physics Folks,

I've been looking at one of the final production runs we collected this spring with the diamond radiator (Run 3185).  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.
