ROC curves for the unknown PSF experiment. The angular selection criterion is 10 mas and the contrast is of up to one magnitude. The curves for the single channel (e1, e2, and R2, denoted N(e1), N(e2), and N(R2)) are shown along with the combined three-channel classifier (denoted ACF), the RF, and the ANN methods. All curves are colour-coded with the F1 score computed at each threshold. The dashed line shows the performance of a random-guess algorithm. The numerical value in the legend is the AUC of the method.
