    keyword=Efficiency Trigger T4 Reformed

    I updated the file for the MLU that creates the left HRS efficiency
    trigger T4. For the spring experiments, there was no gas Cerenkov. Hence,
    T4 was the "or" of S1 and S2. T4 is now contains the gas Cerenkov again,
    and is the traditional efficiency trigger for the left HRS, which is
    exclusive of T3.

    I also checked the times of S1, S2 and gas Cerenkov "or" at the MLU module
    against the strobe signal. All triggers line up reasonably well with
    each other and the strobe comes comfortably after the detector signals,
    i.e., > 40 ns.
