    keyword=Owl shift summary

    Shift workers:
    Chao Gu(SL), Toby Badman(TO), Yoomin Oh(3rd)

    00:00 Shift starts with production at 0.7000GeV.
    01:05 IHWP flipped to IN by Hall C.
    04:55 Bleed through test: 0.26%
    05:05 Finished production at 0.7000GeV. We got 307M events on this setting. Start to take some dilution data.
    05:25 Finished dilution runs. Start to move LHRS to 1.151GeV for packing fraction run of bottom cell, RHRS to 0.6510GeV, the next momentum setting.
    05:35 IHWP flipped to OUT by Hall C.
    05:45 Take packing fraction run of bottom cell with left arm.
    05:50 Start to move LHRS to 0.6510GeV.
    06:00 LHRS settled. Start production at 0.6510GeV.
    06:05 RHRS settled.
    08:00 Shift ends. We are taking production data at 0.6510GeV.
