A. Reduction of 2D pinwheel geometry to the ring-geometry requires integration over the radial vectors with the angle ξ−θ between them. B. Mapping 2D pinwheel geometry to the ring, showing the weight function w0(ϕ) according to the Eqs 21 and 22 (solid line), and its approximations of the forms 1 + kcos(ϕ) (dotted line) and b + a exp(−|ϕ|/ϕr) (dashed line) for the case of R = d/2.
