    Tony Beresford, David Brierley, Russell Eberst, Marco Langbroek and Greg Roberts
    made observations used in one or more of the following orbit determinations.
    
    The line following each element set states the duration of the underlying
    observational period, or "arc", and the WRMS (weighted average root mean square)
    residuals between the orbit and the observations; the smaller the value, the
    better.
