Comparing the relations between parameters in the model, in addition to the parameters discussed in Sect. 5.2 and Fig. 8. Ionisation parameter (top left) and reflection scaling parameter (top right) against the 0.3 - 10 keV count rates. The remaining panels display the correlations between the different parameters in the model. In each panel, the Pearson rank (r) and p-value is shown to display the significance of each correlation.
