Table C.1

Mean interangle θ for the “Axis of Evil” statistic and even (+) and odd (−) mirror parity statistics S± before and after sparse inpainting on 1000 Gaussian random field realisations of CMB data and using the WMAP7 temperature analysis mask for the inpainted maps.

True After inp. Bias

θ 57.5° ± 9.2° 57.0° ± 9.2° 0.55° ± 10.7°

S + 2.59 ± 0.30 2.59 ± 0.30 −0.00039 ± 0.22
S 2.81 ± 0.35 2.82 ± 0.35 −0.0049 ± 0.26

Notes. The bias is taken by considering the difference (true − inp).
