Notes.

^(*)

Tentative classification based on two color indices only, for all objects but 2003 FB128. In this latter case, taxonomic classification is not possible, but the only available color index would be compatible with BB, BR taxa.

^(a)

From Perna et al. (2010).

^(b)

From Barucci et al. (2011).

^(c)

For the statistical analysis presented in Sect. 3.2, we considered this object as an RR-type: the classification by Barucci et al. (2011) is based on near-infrared colors, where it is easier to distinguish between different taxa with respect to visible colors.
