Estimated weighted mean (triangles) and 68% credible intervals 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 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 figure is for ξ_κ + ⟨ℳ_ap²⟩+⟨ℳ_ap³⟩. The corresponding figure for ξ_κ + ⟨ℳ_ap²⟩ is shown in Fig. C.6.
