    This figure presents oversampling data (12 samples in a helicity window; OS = 
    11, integrate time = 1000) at bpm1I02 (first bpm downstream of cathode). The 
    top 3 plots are Dx, Dy and Aq for the first helicity state being [1]. The 
    bottom three are Dx, Dy, and Aq for the first helicity state being [0]. 
    
    The red markers for the top three plots represent [1] with the previous state 
    being [0] where the black markers represent [1] with the previous state being 
    [1]. But, the Dy plot for unexplained reasons has this reversed. I desperately 
    hoped for consistency here, but ROOT was determined not to allow it. I can't 
    explain why it wouldn't let me be consistent with the Dx and Aq data.
    
    The bottom three plots are all consistent with the red markers being [0] with 
    the previous helicity being [0]. The black markers are for state [0] with the 
    previous state being [1].
    
    Units for Dx and Dy plots are in um vs. ms while the Aq plots are in ppm vs. ms.
