P values when considering the top-ranked number of multiplets for an area threshold of A ≤ 6.27 deg². The x-axis shows how many multiplets contribute to the p value (sorted by highest test statistic value), and the y-axis shows the p value. In this case, adding multiplets (by summing the test statistic values) lowers the chance probability, and we get the best p value of 26% when considering all multiplets.
