Secondary light propagation effects in the full-sky light cone of an observer at redshift z = 0 located at the origin position x₀ = (0, 0, 0) Mpc h⁻¹. The source field is located at redshift z = 0.0835. Top left: angular power spectra of the ΛCDM simulation shown as thin lines. The thick dotted line shows the CLASS estimate, which is only available for the ISW, convergence, and lensing potential. Top right to bottom right: relative angular power spectra with respect to ΛCDM for the simulations of models I–V. The meaning of the labels in the legend is SW: Ordinary Sachs-Wolfe effect. ISW-RS: integrated Sachs-Wolfe and non-linear Rees-Sciama effect. κ: convergence field. Shapiro: Shapiro time delay. ψ: lensing potential.
