Circular apertures for radial profile (Sect. 4.2.1) extraction on top of intrinsic surface brightness maps (Fig. 1a) of the HzRGs sample. In each panel, the blue concentric annuli show the apertures where the radial profile is extracted. The annuli are centred around the host galaxy (central AGN) position (Table 2). The radii of the annuli in each panel are the same in the unit of arcsec for consistence except the smallest radius which is set to be 0.75× seeing for each target. The black bar at the bottom left corner of each panel indicate the 10 arcsec scale.
