    gzero did more parasitic studies of the Hall-C IA and PZT mirror in their beam line at the source. As agreed, the HAPPEX DAQ measured the effect to the Hall-A beam measured in the Hall.
    Below are the results (used profile plot, because the width of the asymmetry is nearly 5000ppm). Shown is the centroid and error in the centroid.

    A more detailed analysis will follow..
