    keyword=Analysis: BB Scintillators Timing Correlations

    Here are the time differences between adjacent scintillator paddles for
    the left and the right PMTs. We require that the left ADC values on the
    paddles be > 500 and on the right ones > 400. The resolution is 50ps or
    better. The numbers below are in nanoseconds.


    Paddles Left Timing Difference Right Timing Difference
    0-1 -0.25 +/- 0.03 +0.024 +/- 0.07
    1-2 -0.21 +/- 0.04 -0.30 +/- 0.07
