Stacked image for all observations from 2005 to 2009 (top panel) and flux density along a cut in the jet direction of 64° (bottom panel). This cut is indicated as a line along the jet axis in the contour map. The common beam for the stacked map is show in the lower left corner of the top panel. For the stacked image, all maps are summed up and divided by the number of images. The contours start at 5 times the noise level and increase logarithmically by factors of 2.
