Keesey, Important ground-based astrometric observations of Eros were provided by several observers including J. Ticha, M. Tichy, P. Shelus, T.J. Johnson, and J.G. Reis. A particularly accurate data set, reduced with respect to reference catalogs based on the Hipparcos star positions, was provided by C. Garradd (Loomberah, Australia) and by R. Stone and A. Monet at the U.S. Naval Observatory Flagstaff Station in Flagstaff, Arizona. A portion of the research reported here was done at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with NASA.
