Notes. System parameters, as obtained by our analysis (second column, Sect. 3.1 for photometry and Sect. 3.2 for RM analysis), and the set we used in this work (third column; fourth column for the reference paper). Solutions for planet eccentricity were fixed at 0 where possible, though Bonomo et al. (2017) reported an upper limit of 0.047. Eccentricity plays a role when shifting to the rest frame of the planet. However, the level is negligible even for small eccentricities. We used the set of stellar and planetary parameters following the literature (third column), while for the ephemeris we used our refined values (second column) after testing that they were compatible. For POLD simulation, we also used values obtained by our analysis due to the higher precision level.
