All Tables

Table 1: Observational circumstances.
Table 2: Taxonomic classification of the ACOs observed in this work and ACOs taken from the literature, as defined by Tholen & Barucci (1989).
Table 3: Spectral slopes, orbital parameters and absolute magnitude of the sample of featureless ACOs, and the D-type inner main-belt, Hilda, Trojan and Cybele asteroids. I is the inclination respect to the orbit of Jupiter.
Table 4: Results of the Spearman Rank-Order Correlations between S'_V and the phase angle $\alpha$ , S'_N, the Tisserand parameter T, the orbital elements of the asteroids (a, e, i, and their nuclear mangnitude H. $r_{\rm s}$ is a measurement of the degree of correlation between the two parameters, $P_{r_{\rm s}}$ is a measurement of the reliability of $r_{\rm s}$ (see text).
