2-point (upper panels), pseudo-collapsed (middle panels), and equilateral (lower panels) 3-point correlation functions determined from the N_side = 64 Planck SEVEM HMHD (left panels) and OEHD (right panels) temperature and polarization map. The red solid line corresponds to the half-difference maps (HMHD or OEHD). The green triple-dot-dashed line indicates the mean determined from 300 FFP10 noise simulations. The shaded dark and light grey regions indicate the corresponding 68% and 95% confidence regions, respectively.
