A library of stellar spectra

Abstract

Spectra for 161 stars having spectral classes O-M and luminosity classes V, III, and I have been incorporated into a library available on magnetic tape. The spectra extend from 3510 to 7427 A at a resolution of about 4.5 A. The typical photometric uncertainty of each resolution element in the spectra is on the order of 1 percent while broad-band variations are smaller than 3 percent. Potential uses for the library include population synthesis of galaxies and clusters, tests of stellar atmosphere models, spectral classification, and the generation of color indices having arbitrary wavelength and bandpass.
