The Funnel Geometry of Open Flux Tubes in the Low Solar Corona Constrained by O VI and Ne VIII OutflowModel calculations show that observed outflow velocities of order 7-10 km/s of C IV and O VI ions, and 15-20 km/s of Ne VIII ions, are not only consistent with models of the solar wind from coronas holes, but also place unique constraints on the degree of flow tube expansion as well as the location of the expansion in the transition region/lower corona.
