A linear polarization field on the sphere can be uniquely decomposed into anE-mode and a B-mode component. These two components are analytically defined interms of spin-2 spherical harmonics. Maps that contain filtered modes on apartial sky can also be decomposed into E-mode and B-mode components. However,the lack of full sky information prevents orthogonally separating thesecomponents using spherical harmonics. In this paper, we present a technique fordecomposing an incomplete map into E and B-mode components using E and Beigenmodes of the pixel covariance in the observed map. This method is found toorthogonally define E and B in the presence of both partial sky coverage andspatial filtering. This method has been applied to the BICEP2 and the KeckArray maps and results in reducing E to B leakage from LCDM E-modes to a levelcorresponding to a tensor-to-scalar ratio of $r<1\times10^{-4}$.
