    keyword=Re: VDC Efficiency for Run 4285

    I do not agree that the VDC efficiency is low for run 4285. The
    efficiencies look normal for the first 50,000 replayed events. On the
    other hand, I have seen that the number of events for every detector is
    quite a bit lower compared to the golden run. This seems to indicate that
    there might have been a long beam (few minutes) trip during the beginning
    of this run. I am replaying the full run to see what the real case is.

    Then I will compare it to a run where we are sure the VDC was fine.

    But for the moment, I think the VDC's were fine during this run.
