Notes. The listed flux densities are plotted in Fig. 2. The errors reported for our integrated flux densities in the S-band are given by the noise contribution in the individual images. The calibration error of about 1% is the same for all spectral windows and is not taken into account here. Ispw stands for the total intensity obtained from the spectral window (spw) images.
