Notes. Columns 2–4 give the final atmospheric parameters Teff (K), [Fe/H] and log g, respectively. Column 5 presents the apparent magnitude in the Tycho band, and Col. 6 the color similarity index SC. Columns 7–9 provide the absolute bolometric magnitude in the Tycho band, mass, and age respectively. The tenth column comments on the chromospheric activity level as compared to the Sun, when available, and gives relevant remarks.
