Notes. The columns give the name of the parameter, its best-fit value with its associated 68.27% HDI and σ, and the priors adopted. Astrocentric orbital parameters are defined at 2456979.5 BJDTDB. ℳ is the mean anomaly computed as ℳ = λ − ω − Ω. We fixed the value of ic = 90º, so Mp of planet -c is the minimum mass. Planet -e has a circular orbit (e = 0, ω = 90º) at the reference time, so e and ω have not been fitted with TRADES. See Sect. 3.2 for details.
