The Small Main-Belt Asteroid Spectroscopic Survey (SMASS) was a wide
wavelength-coverage visible spectroscopic survey of asteroids carried out primarily
at the Michagan-Dartmouth-MIT (McGraw Hill) Observatory on Kitt Peak beginning in
1990. This data set covers the observations for the years 1990-1994 and includes
spectra of 316 asteroids. The data have been published in Xu et al. (1995), Icarus
115, 1-35, 1995.
