Figure 2: VLA maps of 79 radio galaxies from the sample. A label ``L'' or ``C'' by the source name indicates the frequency of observation, namely 1.4 or 4.9 GHz, respectively. Dotted lines help to identify equivalent regions in different frequency maps. The core position is marked with an arrow on each map. The angular scale of the 1.4 GHz maps has been kept fixed, except for objects too extended to properly fit in a single page. In those cases, the map size is reduced by a factor of 2 or 3 (marked with ``1/2'' or ``1/3'', respectively). Map parameters are displayed in Table 3. Contours are separated by factors of $\sqrt {2}$
