    keyword=DEADTIME ISSUE

    From run 4886/4885 , the deadtime started showing negative values.
    We saw from the replay of the run, the problem is with T3. The scalar
    output shows livetime of 3.2 while the other triggers have ~0.75.
    Called Bob and now Kalyan is here. According to what Bob mentioned, we
    took one run only with T3 ( run 4889). But the deadtime this time showed
    "NOT AVAILABLE". Then we took all the triggers as usual except T3 with
    run 3890. And the deadtime looks normal.

    So in short :::
    All in the normal mode----> "-" ve
    Only T3 ----> Deadtime NOT AVAILABLE
    All except T3-----> <10%
