We use Cloudy photoionisation models to predict the flux profiles for optical/IR emissions lines that trace the footprint of X-ray gas in NGC 4151, such as [Fe X] 6375Å and [Si X] 1.43μm. These are a subset of coronal lines, from ions with ionisation potential ≥ that of O VII, i.e., 138eV. The footprint lines are formed in gas over the same range in ionisation state as the H and He-like of O and Ne ions, which are also the source of X-ray emission-lines. The footprint lines can be detected with…
