Difference of the N-point correlation functions determined from the N_side = 64Planck 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 northern (blue) and southern (red) hemispheres determined in the ecliptic coordinate frame. The solid, dashed, dot-dashed, and dotted lines correspond to the Commander, NILC, SEVEM, and SMICA maps, respectively. Note that the lines lie on top of each other. The shaded dark and light grey regions indicate, for reference, the 68% and 95% confidence regions, respectively, determined from the SMICA simulations.
