EBs orbital period vs. the ratio between orbital period and rotational period. Horizontal lines corresponds to P_orb/P_rot = 0.5, 1, 2. In the upper-left panel, colors correspond to the model's confidence. In the upper-right panel, colors correspond to the total error. The lower-left panel shows the three classes defined in Section 5.2.4. The lower-right panel shows the histograms of confidence for the classes on the left panel.
