    keyword=T6 Trigger details

    T6 is now a coincidence trigger between BB E-plane singles and left arm
    T3.  The timing was setup for a 300 MeV/c proton in BigBite.  Higher
    momentum protons will come up to 21 ns faster for 875 MeV/c protons.
    The trigger was formed with an overlap between T6 (window) and T3 
    defines the T6 timing.  The BB singles width was adjusted to 140 ns.
    I would have preferred to make it narrow, but I would have had to 
    re0adjust the retiming circuit again.  The T3 copy is only 50 ns wide
    and comes about 64 ns inside the BB singles window.
