Posterior distributions of the individual parameters for the final iteration. Red and blue coloured lines correspond to the constraints from the corresponding GC subpopulation and black shows the joint posterior. Thin lines are the marginalised posteriors from the different parameter pairs shown in Fig. 9 and the thick lines are the joint probabilities from all of the parameter pairs. The parameters in the bottom row are intrinsic to the two GC populations and we do not combine them.
