Telescope Data Archives

The Smithsonian Astrophysical Observatory Telescope Data Center maintains archives of data from SAO and HCO telescopes.

  • Low-dispersion spectrographs are used primarily for extra-galactic sources.
  • Echelle spectrographs are used for star spectra and radial velocities.
