Properties of the outer jet in 2013. The top row is reprinted from (Punsly 2021). The left panel is a high-sensitivity 43 GHz VLBA image from January 12, 2013, that is designed to highlight the counterjet. The white linear contours levels are (1, 1.64, 2.29 ..... 10) mJy/beam. The red contours are at -0.5 mJy/beam. The right panel is the constant acceleration jet velocity profile associated with the Doppler boosts that convert the sum of the ridge peak intensities of the counterjet into those of the approaching jet (see Equation 1). The middle row is reprinted from (Punsly & Chen 2021). Poynting flux is converted into kinetic energy along the jet, and the conformance to the conservation laws is tight. Increasing W/R from 0.25 and 0.35 in the bottom row has little effect on the nature of the solution, just the normalization.
