    keyword=HAPPEX DAQ check

    Used run 3599 to check all HAPPEX ADCs, and calibrate the DACnoise slope for 
    ADC27 (current integrator for det1 and left quartz profile scanner).
    All ADCs appear to have survived the power failure last night.  And ADC27 
    survived the trip from the 2nd floor of the counting house to the 2nd floor of 
    the Left Arm Hut.
    Important note... there do appear to be a lot more helicity sequence errors 
    than usual.  About 1% of the events in run 3599 failed PANs pair sequence cut.
