Table 3
Priors used for each parameter.
| Parameter | Units | Prior distribution | Description |
|---|---|---|---|
| K | m s−1 | Log uniform [0.1, 20] | Semi-amplitude |
| P−1 | days−1 | Uniform [10−3, 1.5−1] | Orbital frequency |
| e | Beta [0.867, 3.03] (†) | Eccentricity | |
| ω | rad | Uniform [0, 2π] | Argument of periastron |
| λ0 = M0 + ω | rad | Uniform [0, 2π] | Mean longitude at a given reference epoch |
| γ | m s−1 | Uniform [RVmin, RVmax] | Constant velocity offset |
| σJ | m s−1 | Uniform [0, 20] | Additional white noise (Jitter) |
| A | m s−1 | Uniform [−20, 20] | Linear scaling factor with activity indicator |
| αi | m s−1 yr−i | Uniform [−10, 10] | i-th term of the polynomial drift |
| Epoch | BJD | Fixed at 2 455 500 | Reference epoch |
Notes. RVmin and RVmax are the minimum and maximum radial velocity measured, respectively, for each target. All keplerians added to the models have the same priors. (†) Kipping (2013).
