Masses and photometric redshifts of the groups in this study. We select the most massive groups in our sample, M ₂₀₀/ M _☉ ⩾ 3.56 × 10 ¹³. Using only the cleanest groups (characterized by having ⩾ 4 members, well-defined centroids, and no flags on possible mergers or projection effects), and applying appropriate masking, we are left with a sample of 44 groups for this lensing magnification analysis.
