Cluster redshift path density, ﹩g_{c}( W^{\mathrm{min}\,}_{0},\, z_{i}) ﹩, of the high‐resolution sample (S1, ﹩W^{\mathrm{min}\,}_{0}=0.05﹩ Å; left) and low‐resolution sample (S2, ﹩W^{\mathrm{min}\,}_{0}=1.0﹩ Å; right). The thick line is for LOS‐cluster distances ﹩d< 2﹩ ﹩h^{-1}_{71}﹩ Mpc, the thin line for ﹩d< 1﹩ ﹩h^{-1}_{71}﹩ Mpc, and the dotted line for ﹩d< 0.5﹩ ﹩h^{-1}_{71}﹩ Mpc. The vertical dashed lines depict the redshift defined by the rEW detection thresholds. See § 4.2.2 for more details.
