    keyword=How to monitor efficiencies (for shift workers)

    When efficiency of a group drops in either left or right arm, the TDC
    spectrum in spectrometer runs would disagree with golden runs. This could
    happen in any of the group TDC spectrum, such as "L-arm fastbus TDC
    (Gr1-2)", "L-arm fastbus TDC (Gr3-4)", "L-arm fastbus TDC (Gr5-6)", and
    corresponding pages on the right arm GUI.

    Inefficiency could also cause the electron trigger rate to change, making
    EN and EW rates of the same group different from each other by more than
    5%. This can be seen online from Panguin spectrum.
