tokens: directions, uncorrected for Faraday rotation. The FWHM dimensions and orientation of the elliptical Gaussian restoring beam are indicated by a cross in the lower left corner of the map. Figure 4.4421. Source 1954+513 at epoch 2011-Aug-26. Each panel contains two contour maps of the radio source, the first consisting of I contours in successive integer powers of two times the lowest contour level, with linear fractional polarization overlaid according to the color wedge. A single negative I contour equal to the base contour level is also plotted. The second map includes the lowest positive I contour from the first map, and linearly polarized intensity contours, also in increasing powers of two. The sticks indicate the electric polarization vector directions, uncorrected for Faraday rotation. The FWHM dimensions and orientation of the elliptical Gaussian restoring beam are indicated by a cross in the lower left corner of the map. Figure 4.4422. Source 1954+513 at epoch 2015-May-18.
