Abstract

The physical properties of the line emitting material in AGNs can be derived from well known line ratio diagnostics related to H-like and He-like ion transitions. Here, we show how to get this information (size, location and geometry of the emitting clouds) by a fit procedure of the overall observed spectrum with theoretical models developed by using the photoionization code CLOUDY. Application to NGC 4051 in its low flux state is shown.
