Monopole and dipole component estimates after applying the spatial filter of Kashlinsky et al. (2008) on WMAP-7 W-band data (black lines) and on Planck 2D-ILC maps (red lines). Estimates from real MCXC clusters are displayed by vertical, dot-dashed lines. Histograms are obtained after repeating the analysis on 1000 random cluster configurations, with averages indicated by the vertical, solid lines. The y-component appears discrepant here, but compare with Fig. 11.
