No feedback ${\rm Ly}n\rightarrow {\rm Ly}(n-1)$ has been included. Upper panel: as a function of the redshift of emission (see Eq. (1) in Rubiño-Martín et al. 2006). Lower panel: relative to the CMB blackbody as a function of observing frequency $\nu$ .

$\begin{figure} \par\includegraphics[width=8.8cm] {eps/7333f003.eps}\end{figure}$ Figure 2: Changes in the free electron fraction due to inclusion of Lyman-series feedback relative to the reference model without feedback. The computations were performed for a 15-shell atom where for the Lyman-series the escape of photons was modeled using the Sobolev approximation. The curves are labeled according to the sequence of feedback that was included. For example, $4\rightarrow 3\rightarrow 2$ indicates that Ly $\gamma \rightarrow$ Ly $\beta$ and Ly $\beta \rightarrow$ Ly $\alpha$ feedback was taken into account. Also the full result for the 30-shell hydrogen atom is shown, where feedback up to n=30 was included.

The results are based on the computations for a 15-shell hydrogen atom.

The computations were performed for a 5-shell atom where for the Lyman-series escape the Sobolev approximation was used. Note that the absolute value of $\Delta X_{\rm e}/X_{\rm e}$ is ${\sim } 10^{-6}$ only.

The differences were computed using our modified versions of CMBEASY (Doran 2005), which allows loading of pre-calculated recombination histories, and where the corresponding RECFAST-routine was improved to achieve higher numerical accuracy with solvers from the NAG-library.
