Notes. Parameters are the mass Mk, period Pk, semi-major axis ak, and inclination Ik with respect to the sky plane. By convention, inclinations are given with values Ik ⩽ 90°, but transit and radial velocity data cannot discriminate between an inclination value Ik or 180° − Ik. Uncertainties are assumed to be Gaussian; quoted intervals are 1σ. Parameters come from the preprint by Santerne et al. (2019) except the mass of planet d (see text). The star mass is taken to be 1.16 ± 0.04 M⊙ for consistency with the other parameters of Santerne et al. (2019). The inclination of the non-transiting planet g is assumed to be 88° as in Santerne et al. (2019).
