Figure 1

Illustration of the probability distribution for the background count measurement and the target count measurement. The target count measurement (T) represents the summation of source count measurement (S) plus the background count measurement (B). Probabilities (P) for true positive, true negative, false positive, and false negative are shown for target count rates at three standard deviations above the mean background count.
