Radial profiles of the coronal hole plasma parameters for the considered models: a) electron density; b) electron temperature; c) parallel (solid lines) and perpendicular (dot-dashed lines) components of the H I kinetic temperature; and d) outflow wind velocity. Electron densities and temperatures from Ko et al. (1997), David et al. (1998), Wilhelm et al. (1998), Esser et al. (1999), and Antonucci et al. (2004) are also reported for comparison.
