    Tony Beresford, David Brierley, Scott Campbell, Russell Eberst, Peter Gertson,
    Steve Newcomb, Alberto Rango, Peter Wakelin and Brad Young 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.
