Description:
    This table presents stellar atmospheric parameters, absolute
    magnitude, mass, age, equivalent width of the λ6708 Li line,
    and non-LTE Li abundance. For the majority of stars the absolute
    magnitude has been derived from Hipparcos parallaxes but in a few
    cases (marked by :) a photometric value derived from the c1 index
    is given. Most stellar ages have errors of around 20% but those marked
    with `:' are more uncertain, and for stars close to the ZAMS no age is
    given.
