Polarization induced by cosmological scalar perturbations leads to a typical anisotropy pattern, which can best be analyzed in a Fourier domain. This allows one to distinguish a cosmological signal of polarization unambiguously from other foregrounds and systematics, as well as from polarization induced by nonscalar perturbations. The precision with which polarization and cross-correlation power spectra can be determined is limited by cosmic variance, noise, and foreground residuals. The choice… Expand
