Total intensity contour maps of 3C 219, showing changes in its morphology over the entire available frequency range. The contour levels are (3, 6, 9, 15, 24,39, 63, 102, 165, 267, 432, 699, 1131)×σ_rms. The basic properties of individual maps together with noise levels, σ_rms, are given in Table 1. Beams are shown in the bottom-left corners and center frequencies in the top-right corners of each panel.
