Distribution of companions with mass ratio and semi-major axis. Upper panel: v with log q > −1.08 as a function of the logarithm of the semi-major axis a in au. Lower panel: distribution of companions with 0.5 < log a < 3 as a function of the logarithm of the mass ratio q. The red lines are best fit log-normal through the observed distributions. The shaded area in both panels corresponds to 1σ uncertainty.
