Jet collimation profile of the receding counter-jet (left) and approaching jet (right) derived from stacked images at all frequencies using pixel-by-pixel analysis. The jet width is plotted as a function of distance from the common reference frame. Power-law fits (solid red lines) indicate a parabolic expansion for both sides, with indices k = 0.47 ± 0.01 (counter-jet) and k = 0.66 ± 0.01 (jet), consistent with magnetically collimated flows.
