Extracted orientation angle, α, ellipticity angle, γ, and degree of polarization, σ, as a function of the harmonic order, n. Although α shows an alternating behaviour for even and odd orders, the ellipticity remains relatively small for all orders. The degree of polarization, σ, decreases with increasing order, but still remains sufficiently high to guarantee a reliable extraction of α and γ.
