Measurements from the RAYGAL 2500 deg² light cone (diamonds) and the CLASS predictions (dashed lines). Top left: matter density–gravitational convergence cross-spectra with relativistic corrections (MB+RSDs) in a single shell at z = 0.7 (blue) and z = 1.8 (orange) in ΛCDM cosmology. The (usual) cross-spectrum between two shells at z = 0.7 (density) and z = 1.8 (convergence) is shown in purple, and the (non-trivial) reverse one (cross-spectra between convergence at z = 0.7 and density at z = 1.8) is shown in green. Top right: relative deviation from comoving matter density–Born gravitational convergence cross-spectrum at z = 0.7 in ΛCDM cosmology due to relativistic effects. MB is shown in green, while the effect of RSDs(+MB) is shown in blue. An estimate of the MB effect using an inverse magnification (|μ_Born|⁻¹) weight is shown as light blue triangles (see text for details) Bottom left: same but for z = 1.8 with MB in green, RSDs(+MB) in orange, and the |μ_Born|⁻¹ weight MB estimate in green. Bottom right: same but for the z = 0.7 (density)-z = 1.8 (convergence) cross-spectrum with MB in light blue, RSDs(+MB) in purple, and the |μ_Born|⁻¹ weight MB estimate in pink. Relativistic corrections are between 50 and 100% for the cross-spectrum at a single redshift. Overall, there is a good agreement with CLASS at the 20% level. Here again the overestimation of the power spectrum is related to the dilution term of the MB effect on the convergence.
