c– M distribution at three mass bins— M ₂₀₀ = 5 × 10 ¹²  h ⁻¹  M _☉ (left from the GS run), 1.5 × 10 ¹⁴  h ⁻¹  M _☉ (middle, HACC), and 8 × 10 ¹⁴  h ⁻¹  M _☉ (right, HACC)—from the halos drawn from the full sample at z = 0. Lines show the Gaussian distribution with standard deviation σ _c / c ~ 0.33 in the left and center panels, and σ _c / c ~ 0.28 in the rightmost panel.
