Comparison between the position-dependent power spectrum in the Planck PR4 CMB temperature data and simulated maps. We average the position-dependent power spectrum over the full sky (upper panel), and the two hemispheres defined by the dipole of each multipole (opposed to dipole in the middle panel and dipole direction otherwise), and compare the observed value to the equivalent from the simulations. We show the percentage of simulations having a lower value than the data. Horizontal black dotted lines indicate the 5% and 95% thresholds.
