We calculate line profiles using a 4-parameter model
3 parameters describe the spatial
and velocity distribution of the emission: Rois the minimum radius of X-ray
emission, while bdescribes
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.
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.
