VLA maps of 4C 70.19 overlaid on its LOFAR map. Left: VLA map of 4C 70.19 at 1.43 GHz from Fig. 4 on the colour image of the LOFAR map at 145 MHz from Fig. 1. The contour levels are (3, 6, 12, 24, 48, 64, 96, 128, 192, and 256) × 0.37 mJy beam⁻¹. Right: VLA+Effelsberg map of 4C 70.19 at 4.85 GHz on the colour image of the LOFAR map at 145 MHz. The latter map was convolved to 15″. The contours are (3, 6, 9, 16, 25, 32, 64, and 96) × 0.29 mJy beam⁻¹.
