Table 3
Priors for the orbital elements of the planet.
| Parameter | Distribution |
|---|---|
| P (yr) | ln(P∕1 yr) is uniform (−6, 5) |
| υ (mas) | log-normal (−2, 1) |
| Ω | von Mises (0, 0.001, support = [0, 180°]) |
| ω | von Mises (0, 0.001, [−180°, 180°]) |
| cos i | Uniform (−1, 1) |
| e | Uniform(0, 0.9999) |
| Tp (yr) | von Mises (0, 0.001, [0, P]) |
Notes. The full model includes both the orbital elements and the astrometric parameters listed in Table 2. The parameters for the von Mises distribution are location and concentration (κ). Other distributions are as in Table 1. The eccentricity is bound to the [0, 0.9999] interval whose upper bound corresponds to an ellipse with a 1:70 ratio between the semi-minor and semi-major axes.
