Appendix A: Radio maps of the 10.5-GHz Effelsberg observations

Here we present the radio maps resulting from the 10.5 GHz Effelsberg observations of 18 sources in our 1-Jy sample of Giant Radio sources (Figs. B1-B4). For all sources, two maps have been presented. The first, which is indicated by an "I'' and has the name of the source on the plot as well, shows contours of total intensity, with E-field polarization vectors overplotted. The length of the vectors is proportional to the polarized intensity. The scale used is $1\hbox{$^{\prime\prime}$ }\!=\!0.1$ mJybeam^-1, except in the case of B0157+405 where $1\hbox{$^{\prime\prime}$ }\!=\!0.05$ mJybeam^-1. The second plot, indicated by "P'', shows contours of polarized intensity with E-field polarization vectors overplotted. Here, the length of the polarization vectors is proportional to the fractional polarization. The scale used is $1\hbox{$^{\prime\prime}$ }= 1\%$ fractional polarization, except in the source B0309+411, where $1\hbox{$^{\prime\prime}$ }\!=\!0.1\%$ fractional polarization. All contours are drawn at intervals of a factor of $\sqrt{2}$, with the value of the lowest contour given in Table A1. In the case of B0309+411, contours above 16 times the lowest contour are drawn at intervals of a factor of 2. Dashed contours indicate negative flux densities; only the first negative contour has been drawn. References to similar 10.5-GHz Effelsberg maps of the remaining eight sources in the 1-Jy sample are presented in the table.

 

 

Table A1: Flux density values of the lowest contours in the contour plots of the Effelsberg 10.5 GHz data (Figs. B1-B4). Column 3 gives the flux of the lowest contour used in the total intensity (I) plot in mJy beam^-1; Col. 4 gives the flux density of the lowest contour in the polarized intensity (P) contour plot in mJy beam^-1; Col. 5 gives the reference to similar maps which have been presented elsewhere
