Correlations between model parameters. Left: The normalisations of the power law (N_pow) and Comptonisation component (N_comt) are correlated over the two observations (top); N_pow against the column density of the obscurer (N_H) (middle); and N_comt against N_H (bottom). Right: Correlations between N_pow, N_comt and N_H against with the 0.3–10 keV count rate for top, middle and bottom, respectively. In each panel, the Pearson rank (r) and p-value is shown to display the significance of each correlation.
