Example of the distribution of galaxies in redshift and overdensity (σ_δ) space for one MC iteration used in this work (MC #82). Included are only those galaxies in the relevant redshift range for our fraction calculations (i.e., 2 < z < 3). Galaxies associated with Hyperion for this iteration are marked in red and field galaxies for this iteration are marked in blue. Unused galaxies for this iteration are marked in gray (which includes galaxies in the redshift range of Hyperion that are not associated with overdensity and galaxies in the field sample redshift range that are associated with other large structure, see Section 3.3.2).
