    13268 - short run


    18.40 - online analysis crashed; reboot coda
    19.50 - Lumi asymmetry widths are a bit wider than expected (~ 1500); this may be due to fluctuations in coolant temp. coming into the target. After consulting with RC, lowered the beam current to 97 mu-A; this seemed to improve things (~1300)
    20.25 - online analysis crashed: reboot coda
    20.26 - reduce current to 95 mu-A, now the lumi widths are down to ~ 1200, so keep 95 mu-A for now.
    23.00 Tried going to 100 uA again; but the widths increased to ~1400; need to go down to 95 uA

    23.25 - take a run for compton, 15 uA run # 13269
