Comparison of lensing maps constructed from the minimum-variance quadratic estimator alone (upper panel) and in combination with the CIB, as traced by the 545-GHz GNILC frequency map (lower panel). The combination is performed on 60% of the sky, defined as the union of the lensing mask and the GNILC mask. Maps show the orthographic projection of the Wiener-filtered displacement E mode, the scalar field with multipoles , with 10 ≤ L ≤ 2000. The left and right panels are centred on the north and south Galactic poles, respectively. While the two reconstruction maps are clearly strongly correlated, the combined map has substantially more small-scale power, due to the higher S/N of the CIB on small scales.
