Luminosity of the [Ne V] line as a function of the AGN bolometric luminosity obtained from the SED-fit. We excluded the 18 sources with only upper limits on their $L_{\mathrm{bol}}^{\mathrm{sed}3\mathrm{fit}}$. The blue line is the best-fit relation obtained via an orthogonal distance regression. The [Ne V] sources are colour coded on the basis of their AGN fraction measured in the 8 − 1000 μm wavelength range.
