Figure 7: A realization of the multiplicative model where the quadrupole (left column) and octopole (right column) exhibit an alignment similar to WMAP. (a): intrinsic (unmodulated) sky from a Gaussian random isotropic realization. (b) (single column): the quadrupolar modulation with and (see (21)) in the dipole direction. (c): the modulated sky of the observed CMB. (d): WMAP full-sky quadrupole and octopole. Adopted from [40].
