Fig. 2
Dependence of line strength on microturbulent speed vturb. As in Fig. 1, the same stellar atmosphere model computed with vturb = 2 (dots), 10 (dashes) and 15 (continuous) km s-1 is shown. The behaviour of the stronger He i lines is different from that of weaker lines. In the H-lines, the dependence on vturb is strongest in the line wings.
