Number of detected planet candidates (per bin) with respect to parallax and M_*. The sensitivity curve of Gaia for detecting 2–13.5 M_J companions at 1–3 au beyond a significance of 2.7–σ is overplotted in red showing the regions where more than 10, 20, 50 and 90% of companions are detected. The distribution of the Gaia sources satisfying steps 1–3 (Fig. 2) is also overplotted in white solid lines. The dashed thick white lines bound the region within the magnitude range of our sample, that is G-mag within 3.5–16.
