Top: predicted distribution of the tSZ and CIB power as a function of the redshift at ℓ = 1000. Bottom: predicted distribution of the tSZ and CIB power as a function of the host halo mass at ℓ = 1000. The black dashed line is for the tSZ effect, while the dark blue, light blue, green, yellow, orange, and red dashed lines are for CIB at 100, 143, 217, 353, 545, and 857 GHz respectively. The vertical solid black line shows the maximum redshift in PSZ2 (top panel) and the minimal M₅₀₀ in PSZ2 (bottom panel).
