We note that we have written the propagation phase in terms of angle and wavelength rather than in terms of spatial frequency as done by Goodman. It is for this reason we do not call call the propagation phase a transfer function. We also note that this phase is exact; the Fresnel approximation has not yet been made.

20. Because the DOF dephasing term is odd in theta we need to use the full NA (2Δ0) to get the full dephasing for the DOF term. The tilt dephasing term is even in theta so only the half NA is required here.
21. Here the small correction term does not contain a small parameter (g, γ, d) so we go to second order to maintain reasonable accuracy in the expansion.
