Notes. (a) Planetary models based on CARMENES, SOPHIE, HIRES, and combined CARMENES and SOPHIE RV data. 0p: 0 planets, 1p: one planet, 1cp: one planet on a circular orbit (e = 0). GP and uGP: additional constrained and unconstrained GPs, respectively. Orbital periods rounded to one decimal. (b) Priors as in Table A.2. (c)Gaussian priors for planetary parameters based on posterior solution from Table 4.
