Below is a table of the standard deviation of prepulses for the data taken on April 15th over a span of biases. Consistency of data compared for 0 V data, where two series were taken; results of comparison show some small and some larger discrepancies, most notable being the difference of 7 in standard deviation at 0 V for channel 4.
