Classification	Inclusion Criteria
Concave	A clear dimple in the middle of the cell
Flat	The surface was flat
Convex	The surface curved outward and was rounded (hemisphere)
Mixed Concave/Convex	Part of the surface was convex, going above the cross-section and part was concave, going below the cross-section
Protrusion/indentation on flat surface	The surface was otherwise flat except a small area where there was either a protrusion or indentation
Multiple polygons	The surface was flat and made up of at least two intersecting polygons
