Dual-frequency simultaneous 2 and 8 GHz CLEAN images. The lowest contour value “clev” is chosen at four times the rms level, and the peak brightness is given by “max” (Jy/beam). The contour levels increase by factors of two. The dashed contours indicate negative flux. The beam is shown in the bottom left corner of the images at the half-power level. An epoch of observation is shown in the bottom right corner. Blue and orange spots indicate Gaussian model components 1 and 2, respectively. The brightness distribution is shown at the full resolution of naturally weighted data, while the model components are fitted in a restricted uv-range that is common to both bands, see Sect. 4 for details.
