Likelihood obtained for r = 600 AU and M_P9 = 5 M_⊕. The white portion of the map corresponds to solutions that have a probability greater than 0.997 (3σ) to be rejected. The label D indicates 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% according to the propagated covariance (see Fig. 4).
