Notes. We show the direction of maximum values of the dipole component of the corresponding σ map in each case. The fourth column provides the percentage of σ map dipoles obtained from SI MC CMB maps, greater than 
, for each foreground-cleaned CMB map. We perform these analyses for the four foreground-cleaned Planck maps, for various spherical caps sizes, and also considering the addition of noise and foregrounds to the original CMB map. For the sake of comparison, we included the results from the Commander map shown in Table 1.
