    keyword=Scaler inconsistency in left and right arm

    I looked at the special run 1548 that Bo took last night with left and
    right arm synchronized. The scaler reading in the both arm seems to be
    not in sync. 
    

    - Plot 1 shows the fast clock (103.7kHz) counts vs entry number for left and right arm. - Plot 2 is the zoomed in version of the plot 1. - Plot 3 is the difference between left and right fast clock counts. - Plot 4 shows the difference between left and right fast clock signal vs time.

    All these plots are with full run.

    Plot 2 clearly shows that scaler event for left and right arm are not inserted at the same time, there is some overlap - could be hardware setup?
