All radio component positions in xy-coordinates. Light blue symbols denote the 15 GHz data from Britzen et al. (2019a), and dark blue and orange the new 15 GHz and 8 GHz results obtained in this study. In panel a the symbols are of equal size, while in panel b they are scaled according to the flux density (log). A zoomed-in view of the central region is shown, and all components below a flux limit of 1 Jy are displayed. For better visibility, the core flux has been removed. In this and all subsequent figures, the core position is marked with a black cross. The data of the two plots are available in TablesC.1 and C.2.
