Cumulative mass distribution of potential brown-dwarf companions in the CORALIE survey. The blue dashed line shows the distribution of all 21 candidates. The black solid line shows the distribution for the 11 remaining candidates after removal of the 10 stellar companions. The companion of HD 38529 with M₂ = 17.6 M_J (Benedict et al. 2010) is included. For comparison, the red dash-dotted line shows the expected cumulative distribution if all companions had masses of 80 M_J based on the assumption that the orbits are randomly oriented in space.
