We calculate line profiles using a 4-parameter model
3 parameters describe the spatial and velocity
distribution of the emission: R o is the minimum
radius of X-ray emission, while b describes the
acceleration of the wind and q parameterizes the
radial dependence of the filling factor.
1 parameter, t* describes the level of continuum
absorption in the overlying wind.
A wind terminal velocity is assumed based on UV
observations, and the calculated line profile is convolved
with the appropriate instrument-response function for
each line.
