Comparison of the cINN and an MCMC method when applied to K2-111 b. The data in the lower triangle of each panel (blue points) were generated with the cINN method, and the data in the upper triangle (black points) were generated with the MCMC sampler. In the diagonal panels, we also show the marginalized prior probability (gray). The light shaded areas in the 2D diagrams indicate the 68% HDR, and the dark shaded areas are the 89% HDR.
