Small Main-Belt Asteroid Spectroscopic Survey, Phase II V1.0
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), though several minor changes were made in instrumentation and in portions of the data reduction process. -

PRIMASS-L V1.0
PRIMASS-L is a spectral library that contains the results of the PRIMitive Asteroids Spectroscopic Survey (PRIMASS). As of June 2021 this library contains spectra of about 642 asteroids from 10 families and two groups that had been sparsely studied before. 85% of our targets did not have published spectra and only 40% had visible photometry. PRIMASS-L contains spectra from a variety of ground-based facilities. This survey is ongoing and is expected to contain about 800 spectra by the end of 2022. Making PRIMASS-L publicly available at the Small Bodies Node of the Planetary Data System enables synergies with other data sets containing physical parameters (e.g. polarimetric properties and geometric albedo) and family affiliation. This will push the characterization of the families and primitive material to a new level and will improve our understanding of the evolution of our Solar System and other planetary systems. -

NEAR EARTH ASTEROID TRACKING
The Near-Earth Asteroid Tracking (NEAT) project began as a collaborative effort with the United States Air Force (USAF) in December 1995. It concentrated on the discovery and observations of near-Earth asteroids and comets, collectively called near-Earth objects (NEOs). NEAT ended its observations in April 2007. Throughout its history, NEAT utilized three 1m class telescopes - two on the Hawaiian island of Maui and the 1.2m Oschin Schmidt telescope at Palomar Observatory near San Diego, CA. Three unique cameras were developed and used throughout the program. These data are intended to be usable for photometric analysis of the various objects within the NEAT data.
