Notes. We show the fitted and derived parameters for the proposed planetary companion, the GP hyper-parameters of the quasi-periodic kernel for the correlated stellar RV contribution, and the offsets and jitters of the two RV datasets (HARPS-N S2 to S6, CARMENES) used for the best model of Gl 49. The uniform priors are all limited by the largest reasonable boundaries.
