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

[Justin Stevens]

Thanks everyone for the feedback.  Alexandre also showed the phi modulation at the MCC meeting today.  I'll be presenting this in more detail at the collaboration meeting next week on Wednesday as well.

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.
