Figure 1: The radio spectrum of J1101+7225 at different angular resolutions, corresponding to Table 3. All VLBI measurements are labelled with the observing date. While the flux densities are plotted with error bars, the stars indicate peak brightnesses. Because the peak brightnesses may underestimate the flux densities, the corresponding spectra are dotted / dashed (see Sect. 3.1). |
