Table A.1.
Coefficients for the linear combinations of complex aperture measures to give an E- and B-mode separation, as in Eq. (A.11). Computed from Eq. (A.12). The coefficients are only defined for q ≤ n, being the ones for n = 3 and n = 4 compatible with the ones presented by Jarvis et al. (2004). The values marked with × are undefined by Eq. (A.12), so we can set them to 0, as in Sect. 3.2.2.
