gnomonic projection of dust intensity templates centred at high latitude (l,b) = (90°, − 80°) at a map resolution of 5′. Top: new PSM dust from multi-dimensional GNILC (Remazeilles et al. 2011). Middle: original PSM dust (Delabrouille et al. 2013) based on the model of Finkbeiner et al. (1999). Bottom: Planck 2013 dust model (Planck Collaboration XI 2014). Comparing the top and bottom panels, the improvement in reducing the contamination of the dust by small-scale CIB anisotropies at high Galactic latitude is clearly visible.
