Posteriors for the CMB dipole parameters using the map-space analysis (top) and harmonic-space analysis (bottom). The left panels use the SMICA-NOSZ CMB maps, whereas the right use the 2D-ILC CMB maps. MILCA y map results are shown in orange, and 2D-ILC y map results are shown in blue. Black dashed lines show the best-fit parameters from direct measurements of the CMB dipole. Dark and light contours enclose 68% and 95%, respectively. Titles for each panel give the best-fit results, along with the 68% uncertainties.
