    keyword=rates for 11-07

    Compton rates, HV = 1675 V, y = 43 mm:

    B (Laser Off): from 1 kHz/uA up to 1.5 kHz/uA, but went up to 4.5 kHz/uA;
    S (Laser On): 2.5 kHz/uA to 3.0 kHz/uA when low background;
    (S-B)/B = from 1 to 1.5 in low background, which would be acceptable, but these high background peak are very intriguing... I'd rather not take ddata
