Comparison of the radial velocity baseline with the SPAW-induced velocity boost. The black line shows the unperturbed background velocity v₀. The orange line shows v₀ + δb_r, where ﹩\delta {b}_{r}=\delta {B}_{r}/\sqrt{{\mu }_{0}\rho }﹩ is the radial magnetic field perturbation normalized to velocity units. The green line shows the measured radial solar wind velocity v_r. All quantities are averaged in 3 R_s bins. Error bars denote the standard error of the mean within each bin.
