Ellipsoidal component significance Δ_ellBIC versus eclipse significance Δ_eclBIC of models having one Gaussian and an ellipsoidal component. The color is related to orbital period according to the color scale drawn at the right of the figure, with orbital periods smaller than 10 days plotted in gray and those larger than 180 days plotted in red. The sources labeled in the figure have their folded light curves displayed in Fig. 6.
