Posterior probability distributions for the simultaneous MCMC modelling of the nuclear and extended emission. Contours represent the 68%, 95%, and 99.7% confidence levels. The vertical solid red lines and the red points mark the best-fit values, which we define as the median value of the distribution of individual parameters, while the dashed red lines mark the 16th and 84th percentiles. Median and percentile values for each parameter are reported above the one-dimensional histograms along the diagonal showing the marginalized distributions for each parameter.
