    keyword=re: 150% live-time

    Regarding the 150% live time problem on R-arm:
    1. The trigger rates on L and R arm are the same.
    2. The prescale factors are correctly loaded.
    3. Looking into the data, we see about a 50% excess of
    events in T1 trigger which have no hit in any detector.
    -------------------
    We surmise that the trigger is probably formed correctly (point 1)
    but on its way to trigger supervisor it acquires noise (point 3 above).
    Need an access to check on a scope.
    The problem is seen in cosmics run 20440.
