Also in this case, Athena/X-IFU will play a major role in unveiling the secrets of the obscuring material and the torus in NGC 5347. The inset in the this figure shows clearly that both Fe Kα1,2 lines would be separated and resolved, in addition to the corresponding Compton shoulder. This will enable a better identification and characterization of faint CT sources, with high-quality spectra. It will also allow us to study and identify the various spectral components in these sources, the geometry and covering fraction of the obscuring material.
