$^{a}$~Continuum fluxes are from point-source fits in the ($u, v$) plane, where  3$\sigma$ upper limits are quoted in the case of non-detections. rms calculated from the cleaned image; $^{b}$~Restored beam, using natural weighting. Note that the exact beam size depends on frequency and location of the source in the sky, as well as on the time of the observations, over which time range the data were taken, and exactly which data/baselines were included.
