Quadrupole-octopole alignment in the cleaned Planck PR4 CMB temperature maps. The preferred direction of the quadrupole is given by the orange circle and blue crosses for SEVEM and Commander, respectively. The orange and blue contours, which are almost superimposed, correspond to the areas where S(Ω) (defined in Eq. (6)) is within 3% of its maximum (preferred direction of the octopole), for SEVEM and Commander respectively. The background map is the sum of the SEVEM CMB quadrupole and octopole. The solid and dashed black lines correspond to the galactic and ecliptic planes, respectively. We only show the preferred directions in the northern galactic hemisphere.
