    keyword=Another quick Lumi update

    Had a chance to analyze several more runs.

    TARGET: Below is a short summary of the target asymmetry:

    Reading data file. This could take a few moments... Making asymmetry from 19 runs. Number of Target-UP windows = 18.4392 Number of Target-DOWN windows = 18.0142

    NOTE: a 'window' is a 20 minute period of target UP or DOWN.

    Asymmetry = -3.59025e-06 +/- 3.59026e-06 (normalized by BCM10)

    I don't expect the asymmetry to remain this small - I think it's just a lucky chunk of runs that I analyzed. Looks very encouraging, though.

    HELICITY: Not much of a chance to replay 'helicity' type data: Making asymmetry from 2 runs. Total Helicity'+' counts = 71835 Total Helicity'-' counts = 71832

    Number of Helicity '+' sessions = 2394.5 Number of Helicity '-' sessions = 2394.4

    Asymmetry = 3.40368e-06 +/- 3.40366e-06 (normalized by BCM10)

    As a side note, BCM3s would be best to use, but BCMu3 is still acting funny - I plan on looking into it during the access tomorrow.
