keyword=RUN 75256: Analysis of HHODO top/bottom timing differences

The run had H2Y in the trigger. With some cuts on clean trajectories, I plot the top/bottom raw tdc difference for individual counters.
In the table below, rms is the rms from the histogram, mean and sig are obtained from a gauss fit.
Units are TDC counts, i.e. 0.06 ns/count. That means that 100 counts difference amounts to 6 ns.
Note that the TUL meantimer window is only 5 ns.
