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.
