Likelihood obtained for r = 800 AU and M_P9 = 10 M_⊕: on the left-hand side we show the full map of the likelihood extrapolation. On the right-hand side we show the same map, but for a more restricted color map: the white portion of the map corresponds to solutions that have a probability greater than 0.997 (3σ) to be rejected (T2 criterion). The labels A, B, and C indicate the most acceptable zones (with higher likelihoods) in the ecliptic plane. For comparison, the dotted magenta lines indicate the zones for which T1 is greater than 75% (see Fig. 4).
