He I and He II line profiles from the final model compared to the normalized observed spectrum of [CW83] 0904−02. The spectra have been corrected for radial velocity. We note that telluric lines in the He II/H I, 6560 Å line are particularly strong and also affect the core of that line, in particular near the predicted Hα emission component. Because it was not possible to match the He II/H I 6560 line it was not included in the fit and is only shown for comparison here. The rotational velocity of [CW83] 0904−02 leads to a notable broadening and smearing of the line profiles.
