Correlation diagrams for the PDFs of the RMR model parameters for the KELT-10 b transit. Curved green and light blue lines show the 1 and 2σ simultaneous 2D confidence regions that contain 39.3% and 86.5% of the accepted steps, respectively. One-dimensional histograms correspond to the distributions projected on the space of each line parameter, with the green dashed lines limiting 68.3% of HDIs. The blue straight lines and squares show the median values.
