    The following are based on observations by Greg Roberts and Peter Wakelin.
    
    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.
