Template images used to describe the morphology of the γ-ray emission. From left to right and top to bottom: templates based on the distribution of galaxies, the tSZ signal, the X-ray emission, the radio halo emission, and the radio relic emission. Images are 3 × 3 deg², except for the radio relic (bottom right), which is only 1 × 1 deg². Units are arbitrary, but the integral of all maps over the solid angle is set to unity. For display purpose, the scale is linear from zero to 20% of the peak value, and logarithmic above.
