Results of three posterior predictive checks. Each row corresponds to a PPC considering a different synthetic observation in the test set. Left panel: corner plots showing the inferred posterior distributions for the target properties. The orange lines mark the medians of the marginalised posteriors for each target property which are then assumed as the respective best estimates. The blue lines mark the target “true” values. Confidence scores (CS) of DBNets2.0 estimates (see appendix A) are reported in the upper right corners. Right panel: comparison between the simulated dust distributions with the “true” and “best estimates” values of the systems’ properties. Both the 2D distribution (upper panels) and the azimuthally averaged radial profile of the dust density (lower panels) are compared.
