Notes.
Flow 2 does not show a spatial overlay of the blue and red wings, indicative of it not being as close to the plane of the sky as flows 1 and 3. We therefore adopt a correction factor of 2.9 for the momentum flux of Flow 2 (i.e. i ≈ 57°), based what would be expected from a random distribution of inclination angles (Cabrit & Bertout 1992; Bontemps et al. 1996). If instead an inclination of 75° was adopted, the momentum flux of Flow 2 would increase by a factor 5.
