Notes. First column shows the HD number, second column the astrometric surface gravity and uncertainty, third column the absolute bolometric magnitude in the VTycho band and uncertainty, and fourth and fifth columns are the mass (in solar units) and age (in Gyr), respectively. The Sun is shown in the first row for comparison.
