	Other definitions can be based on the volume ''V(ψ)'' enclosed in a flux surface, or the surface area ''S(ψ)'' of a flux surface.		Other definitions can be based on the volume ''V(ψ)'' enclosed in a flux surface, or the surface area ''S(ψ)'' of a flux surface.

	An effective radius can also be defined for magnetic configurations with magnetic islands, although this typically requires using an interpolation procedure. It may be argued that assigning an effective radius to spatial points inside a magnetic island is not very useful.		An effective radius can also be defined for magnetic configurations with magnetic islands, although this typically requires using an interpolation procedure. It may be argued that assigning an effective radius to spatial points inside a magnetic island is not very useful, since such points are topologically disconnected from the main plasma volume.
