White noise (G) 3.5 ± 2.3 mod Jeffreys (σB)
Rms (G) 6.1
χr2 0.36

dT
Rec. period (d) 11.28 ± 0.05 Gaussian (11.35, 2.0)
GP amplitude (K) 30 ± 10 mod Jeffreys (σdT)
Evol. timescale (d) 97 ± 32 log Gaussian (log 100, log 2)
Smoothing 0.53 ± 0.12 Uniform (0, 3)
White noise (K) 1.5 ± 0.8 mod Jeffreys (σdT)
Rms (K) 1.6
χr2 1.2

Notes. For each hyper parameter, we list the fitted value along with the corresponding error bar, as well as the assumed prior. The knee of the modified Jeffreys prior is set to the median error bars of our B and dT estimates (i.e., 10 G and 1.4 K respectively).
