    keyword=Trigger rates vs N2 pressure in reference cell

    Here is plot showing current normalized average trigger rates(during the
    run) for T1 and T3 vs nitrogen pressure in the reference cell. These
    rates are calculated from the scaler data for the runs 2521 to 2524.

    2521 - 950 torr N2 pressure
    2522 - 765 torr
    2523 - 511 torr
    2524 - 246 torr

    I believe the pressure gauge was not zeroed during these runs..so the
    actual numbers may vary. In any case, the rates seems to scale nicely
    with the pressure.

    Note : For this plot I took good N2 run only.
