Dipole directions for independent 10-multipole bins of the local power-spectrum distribution from ℓ = 2 to 200 in the Commander HM maps with the full-mission common mask applied. This is a finer binning in order to investigate the directional clustering of different multipole ranges. Note that the maps have been rotated about the Galactic north-south axis, such that Galactic longitude l = 180° is in the centre of the map. The top, middle, and bottom plots show maps based on the TT, TE, and EE spectra, respectively. In all panels, we also show the CMB dipole direction, the north ecliptic pole (NEP), the south ecliptic pole (SEP), and the preferred dipolar modulation axis (labelled as “low-ℓ”) derived from the temperature data in Sect. 7.2.
