Table 1: List of the strongest hydrogen recombination lines studied in this paper. We present the three strongest lines for the first three series of hydrogen atom between excited states: Balmer ( $m\rightarrow 2$ ), Paschen ( $m\rightarrow 3$ ) and Brackett ( $m\rightarrow 4$ ). For each transition $m\rightarrow n$ , we show its name, the rest frame wavelength, and the oscillator strength (these values have been taken from Green et al. 1957). For illustration, we also present in the fifth column the redshifted frequency observed today if emission took place at z=1000. The last column shows the optical depth in the line at that redshift (z=1000), as computed using our code.
Table 2: Maximum signal (in absolute value) obtained for each of the lines within the considered cosmological model. It is shown the angular multipole, the redshift and the observed frequency (today) at which we have maximum effect. We also present the (full) widths $\Delta \ell$ and $\Delta \nu _0$ around the peak value, defined as the regions where the signal is greater than 70% of the maximum value. The last two columns show the amplitude of the effect in temperature ( $\mu {\rm K}$ ) and the relative value of the temperature to the primordial CMB power spectrum. All these maximum deviations are negative (i.e. the correction to the power spectrum $\delta C_\ell$ at those maxima is negative).
