Simulated change in the excess mass (EMM; panels A to D) and pair convergence (PCM; panels E to H) around lens pairs when enriching the level of correlated pairs by further sub-dividing the lens samples into slices with width Δz = 10⁻¹, 10⁻², 5 × 10⁻³, 2 × 10⁻³ (left to right). The shear stacks of the slices are combined for the final maps inside the panels. To highlight the relative differences between the maps, all maps are normalised to the maximum signal in the map; the intensity scale varies over the range 10%–100% of the maximum. The maps use the H15 high-z sample and pairs, indicated by the stars, that fall into the close-θ separation bin.
