AGN contribution fraction to the radio emission of QSOs at 150 MHz, as a function of radio luminosity L₁₅₀ (for the MWQSO sample). The grey dots show the AGN fraction of the L₁₅₀ for each source, i.e. the fraction which is in excess from the SF relation accounting for the scatter. The dark cyan line and shaded area represent the percentage of the overall population which have AGN fractions larger than 50%, i.e. are dominated by the AGN. The shaded dark area around the line shows 1-σ binning uncertainties.
