Table 1:   Target stars. Columns: name - star name; l, b - Galactic coordinates (from SIMBAD); $\pi $, $\sigma _{\pi }$ - trigonometric parallax and its error (Hipparcos); K, $\sigma _{\rm K}$ - the equivalent width of the Ca II K line and its error; H, $\sigma _{\rm H}$ - the equivalent width of the Ca II H line and its error; $N_{Ca {\sc ii}}$, $\sigma _{N_{Ca {\sc ii}}}$ - Ca II column density and its error; as, as ref: association membership and reference: H stands for Humphreys (1978), GS for Garmany and Stencel (1992), Z for de Zeeuw et al. (1999). $D_{\rm H}$ - association distance (in parsecs) from Humphreys (1978); $D_{\rm GS}$ - association distance from Garmany & Stencel (1992); $D_{\rm Z}$ - association membership and distance from de Zeeuw et al. (1999); $D_{Ca {\sc ii}}$, $\sigma _{D_{Ca {\sc ii}}}$ - distance estimated from formula (3), and its formal error.
