Notes. Inferred parameters and errors are defined as the median and 68.3% credible interval of the posterior distribution. (a)𝒰[a, b] refers to uniform priors between a and b (only for pyaneti; for UFIT or the FCO method, no priors were set except on the impact parameter b); 𝒢[a, b] to a Gaussian prior centered on a with a 1σ width of b; ℐ [a, b] to modified Jeffrey’s priors calculated using Eq. (16) in Gregory (2005); ℱ [a] to parameters that are fixed to a. (b)Offset against the zero-averaged HARPS-N RVs from serval (column rvs_srv in electronic data).
