This file represents an extension of a file originally prepared by Pilcher (1979) for the old Tucson Revised Index of Asteroid Data (TRIAD) and updated in Pilcher (1989) for the Asteroids II database. The data for asteroids numbered 4045 and higher were either provided by the Minor Planet Center or extracted from the Minor Planet Circulars, which are published by the Minor Planet Center on behalf of Commission 20 of the International Astronomical Union. In some cases, an institution or survey is credited with the discovery rather than an individual. No attempt has been made to correct the inconsistencies in the presentation of names (that is, some names are given with initials and some are not), or in the way locations are specified (for example, Pilcher distinguishes between the Lowell Observatory and Anderson Mesa locations in Flagstaff). Due to the limitations of the ASCII character set, diacritical marks are lost in this machine-readable form. This version of the data set contains the names, designations, and discovery circumstances for all asteroids numbered as of the 1997 February 22 batch of Minor Planet Circulars, and includes 7508 entries.
