Type: dynamical classification of the objects as described in Sect.~\ref{DataAnalysis}. $\Delta$~(AU): distance Object-Earth in Astronomical Units. $r$~(AU): distance Object-Sun in Astronomical Units. $\alpha$~(deg): phase angle in degrees. Opps., is the number of observed oppositions of the object for the observation date.
