    New BCM Charge Coefficients
    ________________________

    The BCM Charge Coefficients were updated as of now in the runend.tcl file (/adev/scripts) following the current and charge calibrations performed on Jan 12, 2001

    U1: 1345 (old: 1348)
    U3: 4114 (old: 4139)
    U10 : 12515(old: 12552)

    D1: 1303 (old: 1341)
    D3: 4034 (old: 4141)
    D10: 12728(old: 13081)

    The Upstream BCM values have changed <0.5% down
    The Downstream BCM values have changed by ~2.8% down.

    As before, the U1 and D1 should be used for currents > 10 uA
    U3 and D3 can be used in full the range (preferably between 1 uA to max)
    U10 and D10 should only be used below 30 uA
