Notes. The planets included are marked with ‘X’ under the approximate period of the signal. The first block corresponds to models using Keplerian orbits, the second to Newtonian models. 𝒩 and 𝒰 denote the priors for the GPs: normal prior 𝒩(125, 5) around the potential rotation, and uniform prior 𝒰(30, 200).
