Dependence of ξ_GG(r) in PPS1/PPS2 on m_lim, δn/n, D₀, and V₀ (scaling recipe as in HG82, φ(L) from TB96a, TB96b; see text). Thin symbols: TB96₁ with the "standard" D₀ = 0.27 (continuous line) and the "renormalized" D₀ = 0.30 (wide₁; dotted line) yielding the same δn/n as TB96₂. Thick symbols: TB96₂ with the "standard" D₀ = 0.27 (continuous line) and the "renormalized" D₀ = 0.24 (strict₂; dashed line) yielding the same δn/n as TB96₁. Correlation amplitude is particularly sensitive to the "parameter" m_lim (in fact, any intrinsic difference between the galaxy data sets PPS1 and PPS2). Parameterizing the density contrast through D₀ or δn/n does not affect this result.
