Normalized distributions of L _{1.4 GHz} for subsamples of our CSS sources. Both panels show the full CSS sample as a solid gray histogram, and the CSS sources with LS < 10 kpc as blue solid line. Panel (a) shows a comparison with sources having LS ≥ 10 kpc (red dashed line), while Panel (b) shows the radio luminosities of CSS sources with sSFR > 0.01 Gyr⁻¹ (orange dotted–dashed line).
