Fig. B.1


Left: relative difference between the CMB TT power spectrum calculated using a value of α/α0 different from unity (in one, a few or all the terms where it appears), and a power spectrum, Cℓ,st, calculated using a standard value of α/α0 = 1. We thus plot ΔC/C = (CCℓ,st) /Cℓ,st[%]. The cases considered are α varying: only in the hydrogen binding energy (solid light blue); only in the Lyα energy (solid yellow); in both the previous two terms (solid purple); in both the previous terms and in the Thomson scattering cross-section (dashed dark blue); in the previous three terms and in the 2 −photon decay rate (dashed red); and in all terms (solid green). In each case, we assume that α varies by + 5% (α/α0 = 1.05) only in the terms considered, while it is α/α0 = 1 in all the others. Right: same as the cases on the left, but for a variation of me of 10% (me/me0 = 1.1).
