Comparison of pairs of foreground subtracted cross spectra, demonstrating consistency of the residuals with respect to the best-fit theoretical model. The red line in each of the upper panels shows the theoretical six parameter ΛCDM spectrum for the best-fit parameters listed in Table 8. The lower panels show the residuals with respect to this spectrum, together with error bars computed from the diagonal components of the covariance matrices of the band averages. The points here are band-averaged in bins of width Δℓ ~ 31.
