Deconvolved jet width and jet width difference as a function of the distance from the core. Left: deconvolved jet width as a function of the distance (projected) from the VLBI core at 15, 43, and 86 GHz. The blue, green, and red markers correspond to slices taken from the 15, 43, and 86 GHz images shown in Figs. 6 and F.1, respectively. The corresponding solid lines mark the power-law fits with their indices: γ₁₅ =  0.36 ± 0.38, γ₄₃ =  0.27 ± 0.13, and γ₈₆ =  0.90 ± 0.06 (see Table F.12). All slices are drawn parallel to the abscissa and are evenly spaced at 50 μas apart. We note that the 86 GHz data points might be indicating a lower limit for the jet width due to dynamic range limitations. Right: difference between the jet width at 15 GHz and 43 GHz (Δr_{15 − 43}; dashed grey line) and 43 GHz and 86 GHz (Δr_{43 − 86}; dashed orange line). In both cases, the median values Δr_{15 − 43} and Δr_{43 − 86} are positive.
