Summary of prior PDFs for orbital parameter inference.
| Parameter | Description | Prior PDF |
|---|---|---|
| K1 (km/s) | RV semi-amplitude | 𝒩(0, σK) [1] |
| f (1/d) | Frequency | ln f ~ 𝒩 (ln 0.1, 2.3) |
| M0 (rad) | Mean anomaly | 𝒰(0, 2π) |
| e | Eccentricity | β(0.867, 3.03) [2] |
| ω (rad) | Argument of pericenter | 𝒰(0, 2π) |
| s (km/s) | Jitter term | ln s ~ 𝒩(−4, 2.3) |
| vz (km/s) | System velocity | 𝒩(−18, 12.2) [3] |
Notes. 𝒩(µ, σ) indicates a normal distribution with mean µ and standard deviation σ, 𝒰(a, b) indicates a uniform distribution between a and b, β(a, b) indicates a Beta distribution with shape parameters a, b.
