Relation between rWBL and planarity. The figure shows a scatter plot of rWBL versus planarity in obligate (blue, circle marker) and non-obligate (green, square marker) interfaces. A few interfaces are observed with very high rWBL and low planarity. These interfaces are extremely dry with very few interfacial water molecules. Their rWBL is not very significant.
