Jet parameters obtained from the ridge line fitting of the Global and VLBA images. (a) Jet width, (b) peak flux density, (c) apparent opening angle, and (d) residuals of the data with the best fit along the jet ridge lines. Error bars are derived from a linear combination of the fitting and imaging error and are only plotted if exceeding the marker size. The values of R_S are computed assuming a black hole mass of 10^8.2 M_⊙.
