The previously defined regions on the nucleus of comet 67P/Churyumov-Gerasimenko have been
17 mapped back onto the 3D SHAP7 model of the nucleus (Preusker et al., 2017). The resulting regional
18 definition is therefore self-consistent with boundaries that are well defined in 3 dimensions. The
19 facets belonging to each region are provided as supplementary material. The shape model has then
20 been used to assess inhomogeneity of nucleus surface morphology within individual regions. Several
21 regions show diverse morphology. We propose sub-division of these regions into clearly identifiable
22 units (sub-regions) and a comprehensive table is provided. The surface areas of each sub-region
23 have been computed and statistics based on grouping of unit types are provided. The roughness of
24 each region is also provided in a quantitative manner using a technique derived from computer
25 graphics applications. The quantitative method supports the sub-region definition by showing that
26 differences between sub-regions can be numerically justified.
