Multi-frequency Wiener filtering of CMB data with polarization and estimation of cosmological parameters
arXiv:astro-ph/9803160
Abstract
We present a method of subtracting the foreground contamination for the measurement of CMB polarization. We calculate the resultant errors on CMB polarization and temperature-polarization cross correlation power spectra for the high frequency instrument (HFI) aboard Planck Surveyor, and estimate the corresponding errors on cosmological parameters.
