Marginal densities for the stellar parameters M, t, X0, Z0, and α of 16 Cyg A (left) and B (right). The central panels show the joint marginal densities of the paired parameters. In the side panels are plotted the individual marginal densities. The red shaded areas in the central panels and the full lines in the side panels represent posterior densities for the baseline case, that is without diffusion of metals. The black contours in the central panels and the dashed lines in the side panels represent posterior densities for models with diffusion of metals. The numbers in each panel give the Pearson correlation coefficient for the two variables. The values in red correspond to the red shaded densities and the values in black to the black contours.
