Lithium equivalent widths of Her-Lyr candidates compiled in this work (circles) compared to the areas populated by the Pleiades (gray, Neuhäuser et al. 1997; Soderblom et al. 1993) and Hyades (dark gray, Soderblom et al. 1990). UMa group members (Ammler-von Eiff & Guenther 2009) are indicated by squares. Effective temperatures and lithium equivalent widths of Her-Lyr candidates are taken from Table 9. Error bars have been omitted for clarity. The symbol sizes of Her-Lyr stars scale with rotational period as is indicated in the figure. Symbols denote final membership according to Table 11. Filled circles identify members (+) while doubtful (o) or possible members (?) are highlighted by open circles. Crossed circles denote rejected (–) candidates.
