Lithium equivalent width versus effective temperature. Same plotting symbols as in Fig. 4. For clarity tiny horizontal offsets are applied to the data for σ Ori and Lupus stars. Overplotted are curves of growth from Zapatero Osorio et al. (2002) for log g = 4.5 and a range of A(Li) = 2.5 − 3.1 as gray shaded and from Palla et al. (2007) for log g = 4.0 (black dotted) and 4.5 (blue solid) and four different abundances between A(Li) = 2.0 and 3.5 as labeled.
