Representation of the MCMC results for Per-emb-50. On the top diagonal, the 1D histograms are the marginalized distributions of the fitted parameters; the vertical dashed lines represent (from left to right panels) the 16th, the 50th, and the 84th percentiles. The 2D density plots represent the bi-variate distributions for each pair of parameters, with one dot representing one sample. The plot shows the posterior sampling provided by 1000 steps of the 400-walkers chain (750 burn-in steps were performed to achieve convergence).
