A Bonferroni correction was applied to critical probability value (α = 0.0018) because of multiple tests. The values of the test statistic are below the diagonal and probability values are above. Probability values where mean number of daily false detections were not significantly different are indicated by *; the values for receivers with the same placement are in bold
