Fisher forecasts for the 1σ and 2σ confidence contours for the ΛCDM cosmological parameters in the f_sky = 70% case. The blue contours show our results when the CMB, CIB, and CIB×CMB lensing constraints are combined. The red contours show the same results when the CIB×ISW cross-correlation constraints are added. There is a ∼17% improvement on the constraints on Ω_Λ and ∼39/35% for τ/A_s, which are strongly correlated.
