Power density for power spectra as a function of halo mass M₅₀₀ and redshift z at ℓ = 200. On the diagonal we display power density for the auto-correlation power spectra. From left to right: contribution to X-ray, CMB weak lensing, and tSZ angular power spectrum at ℓ = 200. Off-diagonal panels represent power density of cross-power spectra, from left to right and top to bottom referring to: X-ray–lensing, X-ray–tSZ, and lensing–tSZ cross-power spectra. The color scale is the same for all panels and represents the total amount of correlation between probes.
