Orbital period and mass ratio values obtained from the best-fitting binary models. Left panel: Distribution of mass ratio (q) and orbital periods (P) with primary masses 0.2, 0.5, 0.6, and 0.8 M_⊙ (blue, red, orange, and green dots, respectively). The solid lines are linear fits of the q and P values for the separate primary masses considered. The grey dashed lines denote the range of favourable q values for the system. 56.6 % of the models have mass ratios between 0.5 and 1.5. Right panel: Distribution of the period of the best-fit models. We see three significant period distributions at ∼6 d, ∼18 d, and ∼39 d, with the 39 d distribution being more probable (51%).
