Marginalised parameters of the wabs (top), wabs+scattering, sphere+pexmon+scattering and wabs+pexmon+scattering model (bottom) for source 179. The posterior probability density distribution, normalised to the maximum, is shown by grey bars. The blue line indicates the cumulative posterior distribution. For summary of the error, the median and 10/90% quantiles can be used, or as the blue error bar indicates, the 1 standard-deviation equivalent probabilities.
