Notes. Significant correlation are marked as bold in the text. denotes the bulk densities dataset excluding 2002 WC19. D1 denotes the primary’s diameter. N is the size of the dataset, Spearman’s-ρ ± ε is the Spearman’s rank coefficient with the error estimate by Curran (2015) method, the p-value is calculated for null hypotheses: Spearman’s-ρ = 0.
