Table 1

Geometric albedo, bulk density and frequency for different taxonomic classes in an H-limited sample.

Class pv ρ Frequency

C 0.06 ± 0.05 1.5 ± 0.5 16%
S 0.18 ± 0.05 2.5 ± 0.5 62%
X 0.30 ± 0.10 2.8 ± 0.7 22%

Notes. The table reported the median m and standard deviation s of lognormal distributions. The mean and standard deviation of the associated normal distribution are calculated as μ = ln(m) and σ such that (eσ2−1)e2μ + σ2 = s2.
