Caption: Figure 12.

Mass–separation marginal posterior for 14 Her (HIP 79248). The small points represent draws from the posterior, colored by eccentricity. The horizontal axis shows the 3D separation between the companion and the host star, in au, at mid-2015. The larger colored markers present the masses and semimajor axes of the two known planets as retrieved from the accepted entry in the NEA.
