Fig. 17
Cross-spectra of the Planck MV lensing potential with several
galaxy catalogues, scaled by the signal-to-noise weighting factor
defined in Eq. (53). Cross-correlations are detected at
approximately 20σ significance for the NVSS quasar catalogue,
10σ
for SDSS LRGs, and 7σ for both MaxBCG and WISE.
