Completeness to accreting companions for the 14 stars surveyed by GAPlanetS as a function of semimajor axis (astronomical units) and mass (MJ) for the four combinations of models. The color scale shows the depth of the search or the number of stars to which the survey is complete. The rows dictate the ﹩\dot{M}-M﹩ relations, with the top being the stellar (B23) model and the bottom being the planetary (SH15) model. The columns define the LHαLacc scaling, with the left being the stellar (A17) and right being the planetary (A21) scalings. The contours show the completeness to 2.5, 5, 7.5, and 10 (out of 14) stars in the sample.
