Eccentricity significance. The posterior distribution of the eccentricity is shown in blue. The normal distribution with µ = 0.00188 and σ = 0.00035 in blue is compared to a normal distribution with the same variance but shifted to have its mean at zero (orange curve). The spikes in the posterior distributions are highly investigated regions, such as local minima, where the chains were probably stuck before converging to the global minimum.
