Bundle of ROC curves, for both halo subtraction methods, and for various fake planet injections separations; a zoom for FAP between 0 and 10⁻² is included. The random classifier, which validates or invalidates detections with the same probability of 0.5 is shown as a dotted diagonal line for comparison. AUC stands for area under the curve; by definition, the AUC of the random classifier is equal to 0.5. Contrast curves are located on ROC curves at DP = 0.5 (and 0.25 and 0.75 to built error margins as in Fig. 10 for example) and FAP = 2.87 × 10⁻⁷ (corresponding to a 5-σ confidence interval). Data is lacking to produce an accurate curve, especially around FAP = 2.87 × 10⁻⁷, but this still shows that, within the 1-σ margin of error, the two stellar halo subtraction methods have relatively equivalent overall robustness as well.
