Wind model in NGC 4217. We show the vertical profiles of the relevant parameters: wind velocity (top left), cross-section of the flux tube (top right), magnetic field strength (bottom left), and thermal electron density (bottom right). The estimate for the escape velocity is shown as a solid line (in the top-left panel). In bottom-right panel, we also show a possible profile of the electron density from X-ray data using a scale height of 8 kpc with arbitrary scaling.
