   Figure 1. Contour plots for those sources which have significant structure.
 The half-power synthesized beamwidth is represented by a shaded ellipse. The
 contour interval in mJy per beam is indicated beside the letters 'CI'. In some
 cases, two contour intervals are used, in which case the three numbers refer
 to the initial contour interval, the maximum contour for that interval and the
 subsequent interval respectively. All zero contours are omitted, negative
 contours are shown broken and are always drawn at the initial contour
 interval. Crosses mark the positions of optical objects which are discussed in
 Paper II. For the source 1018 + 37, contour plots are shown for both the 4.1-
 and 5-GHz observations, since neither fully represents the source structure.
