Probability distributions showing correlations between the r_c, h_max, and ℛ parameters of the reflkerr_elp model with a weakly ionised disc (see Table 3) fitted in the 1.1–10 keV range to the VL (top left), L (top right), M (bottom left), and H (bottom right) spectrum, obtained in the MCMC analysis using xspec_emcee implemented by Jeremy Sanders. The results of this analysis are presented using package corner (Foreman-Mackey 2016). The contours in the 2D plots correspond to the significance of σ = 1, 2, 3. The histograms show the probability distributions for the individual parameters.
