Fig. 2


Uniform weighted VLBA 43 GHz CLEAN images with fitted circular Gaussian components. The restoring beam is 0.39 mas × 0.14 mas in PA = −14°, plotted in the bottom left corner. Observing date and the first contour (f.c.) are plotted above each map. The first contours are all set to three times the rms noise level of each map, increasing by a factor of 2.
