Formulae in this chapter refer to series expansions and, hence, are only valid approximately, if convergent, unless otherwise noted. Here and in the following, (r, θ, φ) are spherical coordinates, R(θ) or R(θ, φ) are the surface functions, P l (cos θ) is the Legendre polynomial and Y lm (θ, φ)are the spherical harmonics.
