MASSCW flux-density–weighted mean redshift results. Top: distribution of calculated via KDE from our prior’s 10³ realisations of I_ν and (shaded grey), which are limited to z_max = 0.2. The median is (solid grey). Furthermore, we show the variety of geometric model predictions for when similarly limited to z_max = 0.2, assuming flat priors on all model parameters (shaded green; see text for details). The median is . As a concrete example, we show the flux-density–weighted mean redshift of a single model that reproduces the data median (solid green). This model is given by l = 75 Mpc, d₁ = 60 Mpc and β_c = −4/3. Bottom: predictions for considering filaments only, varying all three relevant geometric model parameters: α_f + β_f, l and d₁. The two d₁ = 50% l curves are virtually indistinguishable.
