Fig. 5.
Likelihood considering r = 400, 500, 600, 650, 700, 750, and 800 AU and MP9 = 5, 10 M⊕. The x-axis represents the RA of P9 when the y-axis is its Dec. The z-axis gives the likelihood (see Sect. 3.3 for a definition) of the ephemerides that include perturbations by P9 with respect to INPOP19a. The white portions of the maps correspond to solutions rejected at 3σ (L < 0.003).
