Caption: Figure 6.

Stacked histogram of HSC i-band cModel magnitudes for the Clean VLASS-HSC sample (black outline; total base sample with finite i magnitude). Sources are partitioned into three exclusive redshift-availability categories, with priority spec-z >  photo-z >  no photo-z: (i) objects with a secure spectroscopic redshift (orange), (ii) objects without spec-z but with a reliable photometric redshift satisfying ﹩{\chi }_{\nu }^{2}\lt 3﹩ and σz < 0.1(1 + z) (blue), and (iii) all remaining objects (nonreliable photo-z; gray).
