Notes. * Indicates that the object is a known binary/multiple system. H_V [mag]: average visual magnitude obtained from papers referenced below. Numbers in bold indicate H_R magnitudes instead of H_V. See text for details about the absolute magnitude estimation. B − R [mag] colors (when available). P [h] single or double-peaked rotational period. Δm_R [mag]: lightcurve amplitude. Taxon.: taxonomic color class (Perna et al. 2010, and references therein). Class.: dynamical classification following Gladman et al. (2008). SDO = scattered disc object, DO = detached object.
