Notes. Priors and description for each parameter are presented in Table C.2. The adopted stellar properties used to derive the planetary parameters are the ones from Table 1. (a)Central time of transit (t0) units are BJD – 2457000. (b)The mass for planet c is a lower limit (Mp sin ip) since it is only detected in the RV data. (c)Equilibrium temperatures were calculated assuming zero Bond albedo.
