    keyword=N2 replaced, start data taking

    Jack came in and replaced both N2 bottles.
    The N2 was empty and this shut off all valves.
    We didn't have gas flow for approx 1 hour, but this
    is not enough to cause harm (according to experience).
    If the gas was off for 3 hours you'd notice it in
    detector performance.

    Start data taking with lead target.
    I guess we should not have stopped taking data ... oh well.
