Because J(s) is defined by Eq. (70) only over directions s from the origin into the z ≥ 0 half space, we assume J(s) = 0 for all other s. This limits the integration in Eq. (72) to the domain p^{2}_{+} + q^{2}_{+} ≤ 1.

Representing a correlation function by a Dirac delta function in the incoherent limit clearly violates the normalization condition g(0) = 1, but is nevertheless a useful approximation [viz., Ref. 2, Eq. (4.31)].
