Fig. 2.
He I and He II line profiles from the final models compared to the normalized observed spectra of CD–31°4800 (UVES, top panels) and LSS 1274 (bottom panels, UVES left, CASPEC right). The spectra have been corrected for radial velocity. Because it was not possible to match the He II/H I 6560 line in LSS 1274 it was not included in the fit and is only shown for comparison. The very sharp absorption lines in the 6560 line wings are telluric lines.
