Lithium equivalent vs. bolometric luminosity for the high probable members (probability larger than 0.75). For those stars with multiple values of W(Li), only our selection is represented (see text). Top: binaries and suspected binaries are included and highlighted with large open circles. Middle and bottom: only single stars are shown. Lithium-rich stars are indicated with large, open diamonds. In the first case, selection B, we used the W(Li) selection based on the S/N, whereas in the second panel, selection A, we show the data based on spectral resolution.
