Posterior distributions for the fitted parameters of the RV+RM model. The results are for data where the last 4 data points of CARMENES 18–10 observations have been masked. The median values are quoted as solutions, with the 16th and 84th quartiles given as uncertainties at the top of each column, which are represented as vertical grey dashed lines. All posteriors are modelled well with a Gaussian function with the exception of the mid-transit time, where a double-degenerate solution is derived, as well as λ and ν sin I_⋆, where slightly skewed normal distributions are used. In the parameter-parameter plots, 1, 2 and 3σ levels are presented as solid blue lines.
