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). The x-axis is the coded date of the cross calibration sets:

1: | 3-5 June 1997 |

5: | 17 June 1997 |

Note that the BND window was switched on June 16, from a polypropylene window, to an aluminized polypropylene window that was approximately one third the area. The BND data point from the first pair has been rescaled to account for this change.

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.
