Locations of MCXC clusters outside the masked region. The colour scale indicates inverse noise squared at the positions of the MCXC clusters. The large coloured circles indicate directions for various dipole determinations: HFI dipole from MCXC cluster locations (green); HFI dipole from shifted positions (brown); CMB dipole (orange); Kashlinsky et al. (2010) dipole (red). The HFI dipole from MCXC cluster locations is compatible with CMB and Galactic residuals.
