Notes. (a)The uncertainties are given as the 16th and 84th percentiles of the posterior distributions (1σ confidence interval), and as the 0.2th and 99.8th percentiles (3σ confidence interval) for the bulk densities (indicated in parentheses) because of the poorly determined radius measurements. (b)Derived from the relation 
, assuming Bond albedo AB = 0.
