Notes. The fractions represent the percentage of objects in each dataset classified as AGN, SFG, or Composite according to the optical BPT-diagram or X-ray AGN/nonAGN by X-ray selection criteria (see details in the text). Unknown class indicates the fraction of objects which have not been observed by XMM-Newton.
