Table 7: Statistics of the age distribution of the sample of G-K stars. "PMS'' denotes stars younger than 100 Myr, "Pl_ZAMS'' stars as old as the Pleiades, "UMa'' stars with an age of $\sim 300$ Myr, and "Hya+'' older than the Hyades. The latter age group also contains 17 evolved stars (LC IV-III, III, and II). The total number of G-K stars is 141.
