Elephant chains PBJ - fixed As

Chains from the analysis of the Elephant simulations for nDGP cosmologies with fixed As kmax = [0.16, 0.18, 0.20, 0.22, 0.24] redshifts = [1.0, 1.2, 1.4, 1.65] observables = [P0, P2] sampled parameters = [b1, c2, omega_c, omega_b, h, ns] + logOmega_rc analytically marginalised parameters = [c0, c2, aP, e0k2, e2k2]针对固定原初曲率扰动振幅（As）的nDGP宇宙学（nDGP cosmology）大象模拟（Elephant simulations）分析所得的采样链 最大波数（kmax）：[0.16, 0.18, 0.20, 0.22, 0.24] 红移值（redshifts）：[1.0, 1.2, 1.4, 1.65] 可观测量（observables）：[P₀, P₂] 采样参数（sampled parameters）：[b₁, c₂, ω_c, ω_b, h, n_s] + logΩ_rc 解析边缘化参数（analytically marginalised parameters）：[c₀, c₂, a_P, e0k2, e2k2]
