Description:
    Physical properties and absolute magnitudes of low-mass stars for
    different initial metallicity [M/H], helium mass fraction Y and mixing
    length parameter Lmix: mass (in solar mass), age (in Gyrs) effective
    temperature (in K), log of gravity (in cgs) and absolute magnitudes.
    The VRI magnitudes are in the Johnson-Cousins system and the JHK
    magnitudes in the CIT system. Note that the bolometric magnitude
    corresponds to M_bol(Sun)=4.64. The lowest mass corresponds to the
    hydrogen-burning limit.
