$\begin{figure} \par\includegraphics[width=8.5cm,clip] {eps/8200fig4.eps} \end{figure}$ Figure 3: Dependence of the bound-bound recombination spectrum on the value of T₀. We chose a large value for $\Delta T$ in order to illustrate the effect. All the other cosmological parameters remained unchanged. The results are based on computations including 50 shells for the hydrogen atom (see Rubiño-Martín et al. 2006 and Chluba et al. 2007, for computational details). The whole recombination spectrum is shifted along the frequency axis, but the overall normalization is not affected.

$\begin{figure} \par\includegraphics[width=8.7cm,clip] {eps/8200fig5.eps}\\ \includegraphics[width=8.7cm,clip] {eps/8200fig6.eps}\end{figure}$ Figure 4: Dependence of the bound-bound recombination spectrum on the number of hydrogen nuclei, $N_{\rm p}\propto \Omega _{\rm b} h^2$ . In the upper panel we varied h, but fixed $\Omega _{\rm b} h^2$ and $\Omega _{\rm tot}=1$ , while in the lower panel we changed $\Omega _{\rm b}$ keeping h and $\Omega _{\rm tot}=1$ fixed. All results are based on computations including 50 shells for the hydrogen atom (see Rubiño-Martín et al. 2006 and Chluba et al. 2007, for computational details).
