Christensen, C. G. Abstract Absolute spectral energy distributions for 65 metal-poor stars, spanning a wide range in temperature, luminosity, and metal content, are given. Five local globular clusters and five M31 globulars are also described. The wavelength index sequence of O'Connell (1970, 1973) has been used. Continuum and feature indices are compared internally and with those of the Population I stellar sequence of O'Connell. His discussion of the usefulness of these indices as temperature, luminosity, and metallicity criteria is extended to metal-poor objects. Empirical relationships between /Fe/H/ color, and certain feature indices have been calibrated and applied to 19 objects with previously undetermined /Fe/H/ values.
