Measurements from the RAYGAL 2500 deg² light cone (diamonds) and the CLASS predictions (dashed lines). Top left: gravitational convergence auto-spectrum with relativistic corrections (MB and RSDs) in a single shell at z = 0.7 (blue) and z = 1.8 (orange) in ΛCDM cosmology. The cross-spectrum between two shells at z = 0.7 and z = 1.8 is shown in purple. Top right: relative deviation from gravitational convergence angular auto-spectrum (under the Born approximation) at z = 0.7 in ΛCDM cosmology due to non-trivial relativistic effects. The full effects of MB (with s = 0) are 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 light green, RSDs(+MB) in orange, and the |μ_Born|⁻¹ weight MB estimate in green. Bottom right: Same but for the z = 0.7 − z = 1.8 cross-spectrum with MB in light blue, RSDs(+MB) in purple, and the |μ_Born|⁻¹ weight MB estimate in pink. MB effects are not accounted for in CLASS and cause ∼10−30% deviations. This confirms that the dominant effect is the dilution term of MB related to source averaging (as opposed to angular averaging).
