Ratio of the FWHM emission line width of [Fe ii] 1.644 μm, corrected for instrumental broadening, to the jet velocity inferred from the radial velocities in Figure 2 and the known inclination angle of the flow. Points and error bars for both the redshifted and blueshifted jets derive from the on-axis values in Figures 2 and 3. The expected ratio for radial flow with an opening angle of 4° is ~ 0.05, so an extra source of line broadening is present in these flows. The redshifted and blueshifted points are offset from one another slightly in distance for clarity.
