Zoom of the leading IWS of the simulation with a surrounding disk wind at time t = 48 yr. Left: density stratification (with the logarithmic color scale given by the top bar in g cm⁻³), center: radial velocity (with the linear scale of top bar in km s͔–1) and right: axial velocity structure (with the linear scale of the top bar in km s⁻¹). The white contours show the surfaces of 50 % (solid line), 10 %, 0.1 % and 0.001 % (outer contour) jet material mixing fractions. The cyan asterisk is the predicted vertex of the cavity, the cyan dash-dotted line in the predicted boundary of the cavity, and the cyan curve is the fitted shape of the bow shock.
