Constraints on the presence of companions from direct imaging and Gaia-Tycho2 proper motion differences. The detection limits from direct imaging, combining various datasets at different projected separations, are shown as a blue continuous line (the <200 AU region of the blue line comes from the speckle interferometry). The continuous black line shows the expected mass and projected separation of companions compatible with the nominal Gaia-Tycho2 proper motion difference, while the shaded gray area shows the lσ limits considering realistic distributions of orbital parameters.
