Thirty Years of Echelle Spectra Made Public
Abstract
From December 1978 through May 2009, more than 250,000 high dispersion (R 36,000 or 8.7 km/sec) optical spectra of bright stars (V<13 on 1.5m, V<15 on 6.4m) were recorded by the Smithsonian Astrophysical Observatory (SAO) on echelle spectrographs on the Tillinghast 1.5-meter reflecting telescope and MMT telescope on Mt. Hopkins in Arizona and the Wyeth 1.5-meter reflecting telescope in Harvard, Massachusetts. The spectra were obtained primarily to obtain radial velocities and stellar parameters. The spectra have been uniformly reduced and are being made public as a valuable resource in combination with Gaia proper motion and parallax measurements.
