Intensity profiles of the jets of 4C 70.19. Top: Intensity profiles measured in the LOFAR 145 MHz map (Fig. 1) and the combined VLA+Effelsberg maps at 4850 MHz (Fig. 6) along the propagation lines presented in Fig. 8. The plot is limited to 3′ from the core to better present the inner parts of both jets. Bottom: Intensity profiles as in the upper panel, but along the entire propagation path. In both panels, the vertical dashed line marks the optical D₂₅ luminosity limit of the host galaxy NGC 6048 and the main turning points of the jets are marked with crosses and are labelled in the corresponding colour.
