Representation of the MCMC results for FT Tau. On the top diagonal, the 1D histograms are the marginalized distributions of the fitted parameters; the vertical dashed lines represent (from left to right) 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 500 steps of the 1000-walkers chain (800 burn-in steps were performed to achieve convergence). We note that in order to obtain an independent set of samples, the chain has been thinned by a factor equal to the autocorrelation time (~80 steps in this case).
