Abstract

The H-R diagrams of dM, sdK, and sdM proper-motion stars are examined. A method for integrating energy distributions using discrete weights is proposed. The bolometric corrections are assessed at various wavelengths and a method for obtaining luminosities even if a star lacks IR data is presented. The color-luminosity diagrams suggest that high-velocity, low-metallicity stars of the halo are subluminous. It is found that the apparent cutoff in the halo is a bolometric magnitude of about 12 m.
