a, b show the posterior marginal probability density functions of vS and vP, respectively. c Histogram of the occurrence of layer interfaces. d Extracted (black line) and modeled ellipticity curves for models drawn from the posterior PDF (ML maximum likelihood, MAP maximum a posteriori). Vertical bars indicate the expected data error (used as inverse data weight). e Posterior histogram of the number of layers.
