Summary of cluster statistics for three “single” units in Figure 3: False-negative events

	Single cluster error	Multiple cluster errors					Composite
	Single cluster error	Overlap of clusters				Censored spikes, f₃ⁿ	Composite
	Undetected spikes, f₁ⁿ	1 – 2	2 - 3	3 - 1	Sum, f₂ⁿ	Censored spikes, f₃ⁿ	Computed as [1 − (1 − f₁ⁿ) (1 − f₃ⁿ)] + f₂ⁿ
Unit 1	0	0		0	0	0.028	0.03
Unit 2	0	0	0.017		0.017	0.016	0.03
Unit 3	0.001		0.008	0	0.008	0.021	0.03
