Normalised flux for the HZ line from left to right for the PoWR model spectra calculated for the O8, O4, and O2 models. The red spectrum shows the profile resulting from the model incorporating vturb > 0 to reproduce the 2D average density profile. In black, the spectral lines from a PoWR models with the same parameters, but vturb = 0 is shown.
