Supports \(N_\mathrm{eff} \alpha_s \nu w_0 w_a \mathrm{CDM}\) cosmologies.
In the Goku simulations, neutrino masses are assumed to follow the normal hierarchy, rather than three degenerate masses as in many other emulators. For small total masses (\(\Sigma m_\nu \lesssim 0.2\,\mathrm{eV}\)), this difference leads to small but non-negligible deviations, which should be taken into account when comparing results.
\(N_\mathrm{eff}\) and \(\alpha_s\) are also input parameters; because DE2 does not vary them, they are fixed at \(N_\mathrm{eff}=3.044\) and \(\alpha_s=0\).
