Difference of the N-point correlation functions determined from the N_side = 64PlanckSMICA CMB 2015 temperature estimates and the corresponding means estimated from 1000 simulations. Results are shown for the 2-point, pseudo-collapsed 3-point (upper left and right panels, respectively), equilateral 3-point, and connected rhombic 4-point functions (lower left and right panels, respectively). Correlation functions are shown for the analysis performed on negative (blue) and positive (red) hemispheres determined in the ecliptic (solid lines), Doppler boost (DB, dashed lines), and dipole modulation (DM, dot-dashed lines) coordinate frames. The shaded dark and light grey regions indicate the 68% and 95% confidence regions, respectively.
