Notes.Symbol meaning: 
– uniform prior with lower and upper limits; 
– Cauchy prior with location and scale (these distributions were truncated for numerical reasons); ℒ(·,·) – Laplace prior (sometimes called double exponential) with location and scale; ℰ(·) – exponential prior with mean; ℬ(α,β) – Beta prior with shape parameters, α and β, an approximation to the frequency distribution of eccentricities proposed by Kipping (2013); 
– Log-uniform prior with lower and upper limits.
