AIA 1700 Å detection statistics as function of properties. Figure layout as for Fig. 5, except that in all but the last panel distinction is made between true positives TP (AIA detection with Hα detection) and false positives FP (AIA detection without Hα detection) rather than data sets. The peak contrasts are given as percentage above the intensity threshold (quiet-Sun average +5σ for F₁ maximisation, +9σ for P maximisation). Upper row: each panel shows the TP (blue and purple) and FP (red) distribution distributions for the parameter combination maximising F₁ (filled histograms) and P (outlined histograms). Lower row: as Fig. 5 but the symbols in the two scatter plots are colour-coded between TP and FP as in the upper row, and with distinction between F₁ maximisation (filled circles) and P maximisation (open circles). The last panel shows average peak contrasts for the TP detections with the bar lengths showing the rms spreads around the indicated mean values and with similar distinction between maximising F₁ (filled circles and solid lines) and maximising P (open circles and dotted lines). The total TP and FP numbers are given in the top right of the first panel, with slash-separation between F₁ and P maximisation. The vertical and horizontal dashed grey lines in all but the last panel indicate the threshold values for sub-selection of the top 10% longest-lived, largest and brightest events.
