Notes.

^(‡)

Time at periastron for eccentric orbits; time of possible transits for the circular or nearly circular orbits of HD 143105b and HD 12484b.

^(†)

Using the stellar mass and its uncertainty from Table 2.

^(∗)

Significant RV drift detected only for HD 220842; 3σ confidence intervals for other systems.

^(∗∗)

The RV drift of HD 220842 is due to a substellar companion (see Sect. 4.6).
