Notes. Station designations: VLBA₈ is same as above; Ef – Effelsberg; Mh – Metsähovi; On – Onsala; Pb – Plateau de Bure (phased array); Pv – Pico Veleta; Ys – Yebes; and and Parameters listed above correspond to the final, uniformly weighted, untapered image. Labels I–VI correspond to the quasi-simultaneous data forming the spectra in Fig. 8 (see Sect. 3.4).
