Comparison between the observed and synthetic Li i λ6708 line profiles for HD 42618 (upper panel) and HD 43587 (bottom panel). In each panel, the observed spectrum is shown (filled circles) along with the solar one for comparison (open circles). The best-fitting profiles and those assuming no lithium are shown as solid and dotted lines, respectively. The parameters have been derived using the line list of Reddy et al. (2003). The vsini and macroturbulence values adopted (in km s-1) are indicated. The vertical tickmarks in the upper panel indicate the location of the 7Li components.
