Convergence maps in log-scale of a cluster at z = 0.211 with M₂₀₀ = 3.32 × 10¹⁴ M_⊙, including LoS structure up to z = 0.25. Left: Both cluster and LoS structure mapped at 2 arcsecond resolution with the particle light-cone data. Right: Shell of the cluster from the particle lightcone data, with the other shells from the HEALPix maps upsampled from 13 to 2 arcsecond resolution. In the outskirts of the cluster, we observe that up-sampling smooths the LoS structure.
