Notes. We denote uniform distributions between a and b as 
and normal distributions with meanµ and variance σ2 as 
.(i) Separate analysis, allowing eccentricity. (ii) Described by Espinoza (2018); p = RP/R* is the planetary to stellar radius ratio, and b = (a/R*)cos i is the impact parameter. (iii) Described by Kipping (2013).(iv) Around a middle value of −37 750 for Gaia-1b and −36 000 for Gaia-2b.
