    We ran some new configurations to see if we could pinpoint which Arm the unusual deadtime is originating from.

    The following configurations were used:
    Test3 Left arm ROCs only, TS11 not in readout, not buffered, ped subtracted.

    Test10 Right Arm only, TS0 not in readout, not buffered, ped subtracted

    B2ArmNTS11 Same as before, buffered, bother arms + ROC 10

    Test11 Same as B2ArmNTS11 excpet BBTS1 not in readout

    Configuration Run condition Rate Deadtime
    Test3 LHRS singles 500Hz 3%
    Test10 RHRS singles 500Hz 3%
    B2ArmNTS11 LHRS singles 500Hz 3%
    B2ArmNTS11 RHRS singles 500Hz 3%
    B2ArmNTS11 L&RHRS singles 500Hz 9%
    B2ArmNTS11 L&R Coinc 500Hz 5%
    Test11 Production 800Hz 18%
    B2ArmNTS11 Production 800Hz 21%

    These are the facts, I just write them.
