4 Images and observed parameters

For each source four images are presented (Figs. 6-32). They represent the total intensity at 4.7 GHz (upper left), the total intensity at 8.2 GHz (upper right), the spectral index between 4.7 GHz and 8.2 GHz (lower right) and the polarized intensity at 4.7 GHz (lower left) with overlayed vectors indicating the position angles of the magnetic field. The two total intensity maps are at full resolution, the spectral index map and polarized intensity map are at the resolution of the 4.7 GHz image.

For some of the sources we had to rotate the image over 90 degrees in order to best display the source structure. The four images are placed in the same way as with the other sources.

In the intensity maps, the contour levels vary with 2^1/2, which implies a change in surface brightness of a factor 2 every 2 contours including the negative ones. The first non-negative contour is indicated in the caption of each image and is set to 3 $\sigma$, with $\sigma$ the measured off-source rms. The peak surface brightness in each image is also given in the caption.

The contour levels in the spectral index maps are -3, -2.8, -2.6, -2.4, -2.2, -2, -1.8, -1.6, -1.4, -1.2, -1, -0.8, -0.6, -0.4, -0.2 and 0. The grey scale in the spectral index images also ranges from -3 to 0.

In Tables 2 and 3 some of the observed properties of the sources are listed. All source identifiers are for the B1950.0 coordinate system except those marked with J. Table 2 lists the properties of the radio cores, where identified. In Col. (2) we list core positions (J2000 coordinates), in Col. (3) the flux densities of the core at 8.2 GHz, in Col. (4) the spectral index between 4.7 GHz and 8.2 GHz. Column (5) lists the core fraction at a rest frame frequency of 20 GHz.

Table 3 lists properties of the brightest southern and northern hot spots. Columns (2)-(5) list the properties of the southern hot spot, while Cols. (6)-(10) list the properties of the northern hot spot. They are the peak surface brightness, the spectral index between 4.7 and 8.2 GHz, the hot spot fractional polarization at 4.7 and 8.2 GHz and the observed rotation measure at the hot spot position respectively. The 8.2 GHz fractional polarization was obtained in images that were convolved to the 4.7 GHz resolution.
