Evolution of the covering fraction towards the soft excess (red) and hot corona (blue). Black circles denote C f ( SE ) = C f ( HC ) Mathematical equation: $ C_{\mathrm{f}}^{\mathrm{(SE)}} = C_{\mathrm{f}}^{\mathrm{(HC)}} $. We also show flat-top Gaussian model-examples fitted to the Cf evolution of both components; see the main text for details.
