MCMC posterior distributions for the fitted transit parameters. From left-to-right: the planet-to-star radius ratio, transit epoch (BJD−2,450,000), orbital period (d), impact parameter, eccentricity and longitude of periastron parameterised as and , and the stellar radius and mass. The radius ratio, epoch, period, and stellar parameters can be seen to be Gaussian-like. However, the impact parameter and the eccentricity and periastron distributions are non-Gaussian due to their degeneracy with one another. The detrending parameters and LDCs, not shown here, are well represented by Gaussian distributions. This figure was made using corner.py (Foreman-Mackey 2016).
