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 |

2: | 6 June 1997 |

3: | 9 June 1997 |

4: | 12 June 1997 |

Note that in the first two data sets, P10 was used in the detectors. On the last two sets, methane was used.

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.
