MCMC posterior distribution of the HIRES, HARPS, and CARMENES VIS RVs for Gl393 for a model including one circular planetary orbit (parameters K_b, P_b, and T_c,b), a Gaussian Process using the george-code and a quasi-periodic kernel (hyper-parameters h, w, P, and λ), offsets (μ_HIRES, μ_HARPS, and μ_C.VIS), and additional jitters (σ_HIRES, σ_HARPS, and σ_C.VIS). Only solutions with are shown.
