Here we listed the parameters used by the emulators and their respective ranges.

\(k\in[10^{-2},5] \, h\rm Mpc^{-1}\). At higher scales (\(k<0.01 \, h \rm Mpc^{-1}\)) the non-linear power spectrum is extrapolated from the linear power spectrum, while at smaller scales (\(k>5 \, h \rm Mpc^{-1}\)) a power law extrapolation is used to get the non-linear power spectrum.
\(z\in[0,1.5]\). At higher redshift the non-linear power spectrum can extrapolated from the linear power spectrum or using HMCode.
