Same as Fig. 8 but second-order statistics alone. The triangles with error bars are estimated from the MCMC chains for all FLAMINGO models described in Sect. 2.2. Since the LS8 and Planck cosmology is different we plot ΔΩ_m = Ω_m^best − Ω_m^true and in analogy ΔS₈ and and ΔΩ_b. The different colours show cases where parameters are fixed. The stars indicate the best-fitting parameters resulting from a minimisation process that returns the lowest χ². The corresponding figure for ξ_κ + ⟨ℳ_ap²⟩+⟨ℳ_ap³⟩ is shown in Fig. 8.
