Assumed period distribution (upper left) and mass ratio distribution (upper right), as well as the unprojected logarithmic velocity distribution (lower left) and the projected velocity distribution (lower right). The extrapolation of the period distribution from the observed range to an upper limit of 300 years is plotted as a dashed line. This extrapolation has been taken into account in the lower panels that show the velocity distributions. The blue lines show the distributions from Sana et al. (2012), the green lines those from Sana et al. (2013), and the red lines the distributions from Kiminki & Kobulnicky (2012), as detailed in Table 1.
