Photoelectric observations of 130 asteroids were obtained at the University of Texas McDonald Observatory and Cerro Tololo Inter-American Observatory on 150 nights between November 1982 and February 1985. The program objects were primarily sampled from six distinct regions in the asteroid belt to illuminate two specific problems: the role of collisions in clearing the 3/1 resonance Kirkwood gap and the formation and evolution of the Eos and Koronis families. Over 400 individual lightcurves were obtained which when combined allowed rotational periods and lightcurve amplitudes to be derived. B-V and U-B colors were measured for a majority of the objects and absolute magnitudes, H, have been computed.
