Phys. Rev. D 77, 123539 (2008) [7 pages]Harmonic inpainting of the cosmic microwave background sky: Formulation and error estimateReceived 3 April 2008; published 27 June 2008 We develop a new interpolation scheme, based on harmonic inpainting, for reconstructing the cosmic microwave backgroundtemperature data within the Galaxy mask from the data outside the mask. We find that, for scale-invariant isotropic random Gaussian fluctuations, the developed algorithm reduces the errors in the reconstructed map for the odd-parity modes significantly for azimuthally symmetric masks with constant galactic latitudes. For a more realistic Galaxy mask, we find a modest improvement in the even-parity modes as well. © 2008 The American Physical Society URL:
