Secondary eclipse significance Δ_ecl2BIC versus primary eclipse significance Δ_ecl1BIC of all models that contain two Gaussians. Models without ellipsoidal component are plotted in gray. Models containing an ellipsoidal component are shown in color, the color being related to Δ_ellBIC according to the color scale drawn on the right of the figure. Models that have log (Δ_ellBIC) values greater (smaller) than the upper (lower) limit shown on the color scale are plotted in black (magenta). A 1:1 line is added to the figure as an eye-guide. The sources labeled in the figure have their folded light curves displayed in Fig. 6.
