Central panel: same as Fig. 3 but in ecliptic coordinates. The pixels highlighted in the vertical and horizontal directions show the regions where we estimate the maximum distance at which we detect half of the simulated systems, as shown in the right and top panels, respectively. Top panel: distance at which 50% of the systems are detected, for the highlighted pixels along the ecliptic λ = 0°. Right panel: same as the top panel but for ecliptic β = 0°.
