Top: measured dipole modulation power in cumulative CMB multipole bins for Commander (red), NILC (orange), SEVEM (green), and SMICA (blue) as determined from a BipoSH analysis of the data.. Colour coding as in Fig. 32. Note that the measurements in cumulative bins indicate a power in excess of 2σ up to multipole max ~ 320. The value on the horizontal axis denotes the maximum multipole used in the analysis, with min = 2. Bottom: modulation dipole direction as recovered from the SMICA map. The directions found from the other component-separation maps are consistent with these directions. The colour-coded points represent the directions recovered for the specific max used in the analysis, with min = 2. The low- and WMAP-9 directions are identical to those in Fig. 35.
