Normalised distribution of AIA false negatives FN (red) and true positives TP (blue) as function of Hα Ellerman bomb lifetime, area, and peak contrast. Overlaps show up violet. The distributions are summations over the two AIA diagnostics, for each using the parameter combination yielding maximum F₁, and are normalised by the total numbers specified in the first panel. The vertical lines indicate cut-offs for selecting the top 30% (dashed, N = 521) and 10% (dotted, N = 174) of the Hα Ellerman bombs for each quantity.
