Fig. 3
X-ray luminosity as a function of the Hβ FWHM. The vertical dotted line marks the threshold of FWHM(Hβ) = 600 km s-1, while the horizontal dashed line corresponds to LX = 1042 erg/s. Different symbols are related to the optical classification: BPT-AGN as filled circles and BPT-SF as empty triangles.
