    keyword=results from phase trombone change: position differences

    
    I show horizontal and veritcal angle and position.  
    
    Figure 1: baseline, with old optics
    Figure 2: new optics.  Notice change in jitter and average position difference 
    for Y position (almost a 3-sigma effect).  With less 
    statistical certainty, the x-angle position difference may have gotten worse, 
    although we would have had to take data with these new setpoints for a while 
    longer (an hour or two) to be definitive.
    
    Seeing any change at all is strange, only because the pzt slopes didn't change 
    significantly. Compare logen
