ASTEROIDS II MACHINE-READABLE DATA BASE - MARCH 1988 VERSION This data set was assembled by E. F. Tedesco, Jet Propulsion Laboratory, in March 1988 from files provided by the contributors noted below. These files constitute the machine-readable version of Part VI - Tabulation, of the book "Asteroids II" 1988 eds. R.P. Binzel, T. Gehrels, and M.S. Matthews (Tucson, Arizona: University of Arizona Press). Each chapter in Part VI will contain a brief introduction followed by the tabular material. In many cases the chapters will be a subset of the machine-readable form of the data set. For example, one of the enclosed files is a tabulation of proper elements computed by J.G. Williams; these will not appear in the book. The possibility exists that some of the enclosed files, for example the discovery circumstances file, will be updated prior to publication, hence, the version which appears in the book may differ from that contained herein. For this reason, references to data obtained from these files should reference them explicitly. For example a reference to the rotation data base should read "Lagerkvist et al., 1987" in the text and (for the floppy disk version) "Lagerkvist, C.-I., Harris, A.W., and Zappala, V. (1987). Asteroids II machine-readable data base: March 1988 floppy disk version." in the references section. The files contained herein have been deposited with the National Space Science Data Center, Code 633, Goddard Space Flight Center, Greenbelt MD 20771 under the data set name: "Asteroids II machine-readable data base: March 1988 version". This data set is available from the NSSDC on 9-track magnetic tape. If you have used the NSSDC version of this data set, then the full reference should read, for example, "Lagerkvist, C.-I., Harris, A.W., and Zappala, V. (1987). Asteroids II machine-readable data base: March 1988 version, National Space Science Data Center, Greenbelt MD". Naturally, a datum on an individual asteroid, at least one you are discussing in detail, should reference the original source. The Asteroids II machine-readable data base: March 1988 version consists of the following files received by me on, or prior to, 29 March.
