    keyword=Analysis shift summary

    runs collected during shift: 3205, 3206, 3207, 3208.


    Done:
    Online GUI info for all runs checked
    Comment:
    for run 3206 DC rates smaller than usual. This run was beam tuning run.
    Problems:
    N6 Left 41 TDC missing signal.


    Done:
    DC Efficiency and Tracking efficiency was checked for
    all runs with small statistics(2000).
    Comment:
    Efficiency plots looks as usual (see attached figures).
    Difficult to say something about X and Y position from tracking,

    because of small statistics. Start to analyzer run 3208 with bigger
    statistics(10000)

    Done:
    BCA checked for all runs.
    Comment:
    3205: BCA_u1 = 17 ppm, 3206: BCA_u1 = -31 ppm,
    3207: BCA_u1 = -14 ppm, 3208: BCA_u1 = 35 ppm,

    Done:
    analyzed 10000 events of run 3208 with tracking.
    Info:
    X and Y distribution in shower reconstructed form tracking shown in
    attached picture.
