Distribution of asteroids in the (Y − J) vs. (J − Ks) plot for asteroids with (Y − J)_err ≤ 0.118 and (J − Ks)_err ≤ 0.136 (asteroids with errors in Q2 limits). Left panel: the objects for which a final taxonomic class was assigned are shown in blue, while those for which the two algorithms gave a different solution are shown in gray. Right panel: for clarity, the unclassified asteroids are shown as a separate figure.
