Revisiting the CMB homogeneity scale: low multipoles removal effect and extragalactic foreground masking
Removing low multipoles from Planck CMB maps and from Lambda CDM simulations removes the homogeneity scale discrepancy; the paper attributes this to the low quadrupole, but its maps labeled ell>=2 retain the quadrupole.
