Marginal mass and inclination posteriors for planet b based on contributions from different data sets. We find that the model including all data, shown in black, finds a mass of 1.00 ± 0.10 MJup, which is somewhat higher than previous estimates but in the range we would expect for a planet aligned with the outer debris disk. The white contours indicate 1σ and 3σ, while the gray bands indicate the 68.5% CI.
