Power spectra of ﹩\delta _{\mathrm{H}\,\,{}^{{\rm{\small I}}}}﹩ (circles) and ﹩\delta _{\mathrm{H}\,\,{}^{{\rm{\small I}}}}-\delta _{\mathrm{DM}\,}﹩ (squares) of the 12 Mpc box hydrodynamic simulation samples. The physical scale for j is ﹩\Delta v=2^{13-j}\times 4﹩ km s−1. For clarity, the power spectrum of ﹩\delta _{\mathrm{H}\,\,{}^{{\rm{\small I}}}}-\delta _{\mathrm{DM}\,}﹩ is shifted slightly.
