    keyword=adjust def'n of beam on for auto ABU

    This for the automated ABU numbers in the BTA GUI, which I
    suspect the shift workers have been ignoring with a cynical
    smirk since they've been somewhat unreliable lately.

    Previously, due to the beam leakage, the cut to define "beam on"
    was set at 60 nA. But this has become too high, so now I've made
    it 40 nA. This started at 08:21:49 in the log below. I'm afraid
    this cut will be flakey if this leakage continues to fluctuate.

    Shift workers have final say over ABU numbers in BTA, as usual. 
    Units of beam are uA
