Brightness temperature (top panel) and component major axis (bottom panel) as functions of the core distance for both jets. Power laws are fitted (T_b ∝ r^s ;  D ∝ r^d) and the indices are printed in Table 5. Two cases are distinguished: including all data points (red lines) and excluding the gray diamonds, corresponding to circular Gaussian fits whose major axes are smaller than 0.15 mas in size (blue lines). These data points do not seem to be a good representation of the width of the jets, but rather maybe owing to substructures within the jets.
