Default priors used for the GP kernels.
| Parameter | Prior | Unit | Description |
|---|---|---|---|
| dSHO-GP kernel parameters | |||

| σGp | 𝒰 (0, 50)/𝒥(1, 1 X 106) | m s−1/ppm | Standard deviation of the GP, uniform for RVs and log-uniform for photometry |
| fGP | 𝒰 (0, 1) | … | Fractional amplitude of secondary mode |
| Q0,GP | 𝒥 (0.1, 1 × 105) | … | Quality factor of secondary mode |
| dQGP | 𝒥 (0.1, 1 × 105) | … | Difference in quality factor between primary and secondary mode |
| QP-GP kernel parameters | |||
| PGP | 𝒰/𝒩 | d | Period of the GP quasi-periodic component |
| σGP | 𝒥 (1, 1 × 106) | ppm | Amplitude of the GP component |
| ΓGP | 𝒰 (0, 10) | … | Amplitude of the GP sine-squared component |
| αGP | 𝒰 (0, 10) | d−2 | Inverse length-scale of the GP exponential component |
| QPC-GP kernel parameters | |||
| PGP | 𝒰/𝒩 | d | Period of the GP quasi-periodic component |
| σGP | 𝒥 (1, 1 × 106) | ppm | Amplitude of the GP |
