Notes. 𝒰[a, b] represent a uniform prior between a and b, 𝒩[a, b] a normal prior with a median a and standard deviation b, and ℱ[a] a value fixed at a. The uncertainty represents the 68.3% confidence level of the posterior distribution. Please note that the mass MB corresponds to the minimal mass MB sin(i), where i is the orbit inclination.
