Stacked map of 43 GHz total (black contours) and polarized (color scale) intensity images of the inner pc-scale jet of PKS 1510−089 with the direction of electric field vector polarization denoted by black line segments (contour levels are indicated at the top, polarized flux levels are shown in the color bar to the right). All images have been convolved with the same Gaussian beam, shown in the lower right corner.
