    keyword=Compton FADC - FastDAQ Comparison

    Fig. 1 shows accdiff (the difference between two consecutive samples in 
    accumulator 1) for run 60264, a CODA integration run taken with the PMT high 
    voltage off (identical conditions to the FastDAQ run) with a 32 ms integration 
    time. The RMS is 3.45x10^6 (x-axis is scaled by one million before being 
    plotted) raw adc units. With the FastDAQ data, Gregg obtained a width of 1.7E6 
    raw adc units, a factor of two smaller.
