Clockwise from the top left: the redshift versus the 5 GHz power for the 3CRR (crosses), GPS (triangles), and our sample total (closed circles) and core (open circles); the largest linear size (LLS) versus the 5 GHz power for the 3CRR (crosses), GPS (triangles), and our sample total (closed circles) and core (open circles); the redshift versus the K- (GPS and 3CRR) or K_s-band (our sample) magnitude for the 3CRR (crosses), GPS (triangles), and our sample (circles); the K- (GPS and 3CRR) or K_s-band (our sample) magnitude versus the 5 GHz power for the 3CRR (crosses), GPS (triangles), and our sample total (closed circles) and core (open circles). The radio measurements for the 3CRR sample are those of the radio cores, and for the GPS sample it is the total radio power. For our sample, we include the radio “core” power (open circles; Table 7) estimated using funtools in circular regions of approximately the same size (~2 arcsec) and centered on the NIR emission regions N (Table 3; see Sect. 5.2) and the total radio power (closed circles; Table 7), the sum of the power of all the FIRST components (Table 1). We assumed a flat radio spectrum for all sources in order to normalize to 5 GHz. The LLS for the GPS sample were derived from O’Dea & Baum (1997), when a measurement was available. The 3CRR K-band magnitudes are aperture- and emission-line-corrected measurements for a subset of 3CRR sources. For the GPS sample, the K-band magnitudes were obtained by interpolation from NED NIR photometric points. NIR magnitudes for our sample are for the central NIR component, coincident with the center of the radio structure (components N; Table 3). The NIR magnitude system is Vega.
