Notes. (a)In juliet, the length scale parameter is parameterized by its inverse as described in Appendix A. For better understanding, however, we give the direct length scale. The prior labels 𝒰, 𝒩, and 𝒥 represent uniform, Normal and Jeffrey’s distributions (Jeffreys 1946). The x represents either 5.12 days, 30.35 days or 44 days regarding the period of the Kepler signal. The white noise model is always applied on top of the other models in this table.
