Comparison between observed (top row) and model (bottom row) maps of the smoothed distribution of companions in the separation (in au) vs mass ratio plane. We consider here the maps obtained considering only the closest companion, for consistency between the models and the observations. Left column is the whole sample; central column is for stars with a mass > 3.5 M_⊙; right column is for stars with a mass < 3.5 M_⊙. The magenta area marks the region with completeness < 0.2, not used in the analysis.
