Fig. 8


Two He ii lines belonging to BAT99 94. We compare the observed spectrum (solid blue line) with a synthetic spectrum calculated with the same stellar parameters as in Table 1, but with an increased terminal velocity of v = 2500 km s-1 and without rotation (dashed black line). Note that the line widths match, but the shape of the synthetic lines is qualitatively very different from the observed ones.
