MCMC GPR modeling of the Bℓ curve of DO Tau.
| Parameter | Symbol | Value | Prior |
|---|---|---|---|
| GP amplitude (G) | θ1 | 159 ± 48 | Mod Jeffreys (σBℓ) |
| Rec. period (d) | θ2 | 5.128 ± 0.002 | Gaussian (5.1, 1.0) |
| Evol. timescale (d) | θ3 | 600 | Fixed |
| Smoothing | θ4 | 0.87 ± 0.21 | Uniform (0, 3) |
| White noise (G) | θ5 | 22.6 ± 3.6 | Mod Jeffreys (σBℓ ) |
| Rms (G) | 25.4 | ||

Notes. For each hyper parameter, we list the fitted value along with the corresponding error bar and the assumed prior. The knee of the modified Jeffreys prior is set to the median error bar of Bℓ (19 G). The evolution timescale θ3 was poorly constrained by the data and set to 600 d.
