Average scaled SZ profiles for each of the nine Planck frequency bands (decreasing frequency from left to right and from top to bottom). The points within each individual profile are correlated at about the 20% level (see Sect. 4.3.1). At each frequency, the stacked radial profile is obtained from the average of the 62 individual cluster profiles scaled by R₅₀₀ and Φ_i/ ⟨ Φ_i ⟩ , in the x- and y-axis directions, respectively (see Sect. 5.1). The light-red shaded area in each panel indicates the statistical uncertainty about the average observed profile. The solid black line corresponds to the prediction of the universal pressure profile (A10) for our cluster sample in each band, and the two dashed lines indicate its associated dispersion.
