The QSO Fundamental Plane (QFP) relates the host galaxy size (r_e) and surface magnitude (µ_e) with either the x-ray (L_x) or optical (M_V) luminosity of the QSO nucleus. Plotted in the 3-D space defined by these parameters, QSOs lie in a thin plane, tilted with respect to all three axes.
If we look in two dimensions and plot the QSOs in the plane defined by the first two principal axes, we find that different classes of objects are grouped in different regions of the plane. A classification according to radio-loudness shows the best separation. Radio-loud quasars (RLQ) and radio-quiet quasars (RQQ) are distributed in such a way that a 2-D cut (by fundamental plane axes) is more successful than a single parameter cut by, e.g., host or nuclear luminosity.
