Illustration showing the coordinate system. We note that $(\hat{r}, \hat{Θ}, \hat{Φ})$ $\[(\hat{r}, \hat{\Theta}, \hat{\Phi})\]$ is the standard spherical basis. Given the symmetry around the polar axis, the radiation field, at a given position r, in a given direction Ω is a function of two spatial (r, Θ) and two angular (μ = cos θ, φ) coordinates.
