The two (nominally pedestal-subtracted) histograms shown are for a helicity input bit of 0 and a helicity input bit of 1. After a Gaussian fit, the means are 6.52939e+05 +/- 3.06050e+03 (helicity = 0) and 6.39600e+05 +/- 3.06538e+03 (helicity = 1). The shift in the mean is 13,339 which (over 6.6 million samples) corresponds to a pedestal shift of 0.002 FADC channels. This is not large but the error in pedestal subtraction would affect Accumulator 0 asymmetries.
The run number was 18354.
