Notes. We also provide the corresponding visible geometric albedo (pV) as described in Sect. 3. Finally, we tabulate the nominal thermal inertia (Γ) and its value normalised at 1 AU using the mid-value (Rh) between the maximum and minimum heliocentric distances spanned by each object’s IR data set. To convert Γ values to 1 AU we assumed that Γ is proportional to Rh−3∕4 (see the Discussion section). Error bars are 3-σ.
