Notes. The Gaussian priors with mean µ and variance σ2 are displayed as 𝒩(µ, σ2). 𝒰(a, b) shows the uniform prior between a and b. (†)In the calculation of the derived planetary parameters we used the following stellar and planetary parameters from Lacedelli et al. (2022) and Brinkman et al. (2023): R★ = 0.843 ± 0.005 R⊙ and Mp = 2.24 ± 0.20 M⊕.
