Estimation of T₀ and γ using MCMC with power spectrum and IMNN on the Fourier-transformed Lyα forest transmitted flux for CAMELS simulation at z = 2. The expected parameter values are log T₀ = 3.97 and γ = 1.26. The power spectrum modeling for the MCMC approach and the training for the IMNN approach were done with previous Sherwood-Relics simulations. We checked the robustness of both approaches by testing them on a different simulation.
