Comparison of contour plots in the Ω_m − σ₈ parameter space sourced from various studies. The outcomes of our study are represented in purple (WEN cluster) and dark blue (ZOU cluster). In addition, we show the outcomes of previous investigations within our group using the same methodology on a galaxy sample denoted as CUE23 and depicted in green. External datasets for comparison include Planck lensing CMB results in yellow, DES Year 3 cosmic shear results in light blue, and KiDS 1000 cosmic shear results in red. Notably, in contrast to the rest of this paper, the contour levels here are set at 0.68 and 0.95.
