Orthographic projection of the ℓ = 2 to 6 multipoles map extracted from the foreground reduced WMAP Q map, in galactic coordinates. Only half of the map is visible (centred on the galactic north pole), with a mask showing only the area covered by the main SDSS. A graticule grid has been superposed with a 45° step in longitude and 30° in latitude.
