Notes. The angle θ gives the orientation (counterclockwise with respect to galactic N) of the velocity vector. The same as for θbow-shock, which is based on the arc-shape of the 22 μm emission. The angles differ by 23.5° from the angles shown in Figs. 2–4, which are given in the equatorial coordinate system.
