Top: GAPlanetS completeness to companions assuming circular orbits, P(e) = δ_0,e, using the planetary ﹩\dot{M}-M﹩ and stellar L_Hα−L_acc scalings. The color scale and contours are as in Figure 2. Bottom: difference in survey sensitivity when assuming orbital eccentricities following P(e) ∝ 2.1−2.2e (lower left panel of Figure 2) vs. assuming circular orbits, P(e) = δ_0,e. The color bar shows the difference in the number of stars to which the survey is complete (out of 14); positive values indicate eccentric companions are easier to detect.
