SMALL MAIN-BELT ASTEROID SPECTROSCOPIC SURVEY, PHASE II

Metadata Updated: February 28, 2019

This data set contains visible-wavelength (0.435-0.925 micron) spectra for 1341 main-belt asteroids observed during the second phase of the Small Main-belt Asteroid Spectroscopic Survey (SMASSII) between August 1993 and March 1999. The purpose of the SMASSII survey was to provide a new basis for studying the compositional diversity and structure of the asteroid belt. Based on experiences gained from the earlier SMASS survey, SMASSII focused on producing an even larger, internally consistent set of CCD spectra for small (D < 20 km) main-belt asteroids. The observing strategies and procedures used during SMASSII roughly parallel those used in the first survey (Xu et al. Icarus 115 1-35, 1995 [XUETAL1995]), though several minor changes were made in instrumentation and in portions of the data reduction process.
