Super-resolved CLEAN images of 3C 454.3 on 2005 July 14 with contours at 0.1%, 0.2%, 0.4%, 0.8%, 1.6%, 3.2%, 6.4%, 12.8%, 25.6%, and 51.2% of the peak intensity at each image. The 2D Gaussian components in the core region are shown in cyan. (a) At the C band (5 GHz), the features are labelled ‘Ca’ for the upstream feature and ‘Cb’ for the downstream feature or bright component. (b) Similarly, at X band (8.4 GHz), the components are labelled ‘Xa’ and ‘Xb’.
