g−r against rz for extended sources with only optical counterparts in the XPS sample. Black points represent the corresponding training sample. The black solid line shows the 90% limit of the kernel density estimation for the training sample (i.e. the colour space region well covered by the training sample). Green triangles are sources inside the 90% limit, blue circles sources outside the 90% limit.
