Figure 5.3: Burn law k images for all sources at the same angular resolutions as for the RM images:
(a) 0206+35 at 1.2 arcsec FWHM; (b) M 84 at 4.5 arcsec FWHM; (c) 3C 270 at 5 arcsec FWHM;
(d) 3C 353 at 1.3 arcsec FWHM. The corresponding integrated depolarization (DP; Section 5.4) is
indicated on the top right angle of each panel. The colour scale is the same for all displays.
