Fisher forecasts for the 1σ and 2σ confidence contours for the wCDM cosmological parameters in the f_sky = 70% case. The blue contours show our results when the CIB, CIB×CMB lensing, and the CMB along with the external (JLA + BAO and H₀ prior) constraints on the cosmological parameters are combined. The red contours show the same results when the CIB×ISW cross-correlation constraints are added. There is a ∼80% improvement on the constraints on w, ∼29% for Ω_Λ, and ∼43/39% for τ/A_s, which are strongly correlated.
