The best-fit values are given as the median of the posterior distributions, and the uncertainties are given as the 16th and 84th percentiles. (a)We adopted the stellar mass and radius derived by Suárez Mascareño et al. (2021): M = 1.170 ± 0.060 M⊙, R = 1.278 ± 0.070 R⊙. (b)Referred to the stellar descending point.
