Stochasticity parameters α₀ and α₁ corresponding to the HOD curves of Fig. 3. Top panel: Stochasticity for the curves that vary the HOD parameters α_hod, σ_{log M}, and f_cen. Middle panel: Stochasticity for the curves that vary the assembly bias parameters A_cent, A_sat, B_cent, and B_sat (inset: closeup of the curve for A_cent). Bottom panel: Stochasticity for the curves that vary the target values of bias and density. Open and filled squares correspond to the HODs with the lowest and highest parameter values, respectively, for the parameter being varied in each curve. Error bars to the right of each panel indicate maximum spatial jackknife error in α₀ and α₁ across all 11 points in a curve. Errors are plotted point-by-point for galaxy bias (bottom panel) due to the larger range of error sizes for α₁. Dashed lines at α₀ = 1 and α₁ = 0 indicate the stochasticity parameter values corresponding to Poisson shot noise.
