Notes.

^(a)

Statistical and systematic uncertainty estimates are added in quadrature.

^(b)

Computed with naive dipole estimator that does not account for higher-order CMB fluctuations.

^(c)

Computed with Wiener filter estimator that estimates, and marginalizes over, higher-order CMB fluctuations jointly with the dipole.

^(d)

Higher-order CMB fluctuations are accounted for by subtracting a dipole-adjusted CMB map from frequency maps prior to dipole estimation.
