The solid boxes are the monitor detector data points. The open triangles are the BND data points. The uncertainty in the data is approximated by the size of the points. The y-axis is the net detector rate, normalized for anode emission current (counts/µC). All of these data were obtained on 6 June 1997. The first pair was obtained as part of the June 6 cross calibration series. The subsequent eleven pairs were obtained as the polypropylene filters were intentionally moved by small amounts.

The graph on the right plots the ratios of the MD and BND data points, with error bars representing the poisson uncertainty in the data.
