Left: SMFs of the outskirts (2.5 ≤ n_σ < 4.0) and overdensity peaks (4.0 ≤ n_σ) of Hyperion. The coeval field and COSMOS2020 fit are identical to Figure 6. Right: Best-fit Schechter functions for the outskirts and overdensity peaks of Hyperion, and the coeval field. The solid lines correspond to single-Schechter fits allowing all three parameters to vary freely; the dot-dashed lines correspond to fits fixing the power-law slope to α = −1.3. The best-fit parameters for each fit are given in Table B.1.
