Fig. 2
(Binned) Modified spectra from Eq. (35) plotted as function of dark energy spectral index. Amplitude ϖ0 = 0.9 is used in all instances. Dark energy spectral index values of nde = 0,1,2 are used in this plot. The modified spectra are plotted against the binned WMAP 7-yr data (black stapled line) and the best fit ΛCDM spectrum (black solid line). Error bars indicate 1σ cosmic variance + measurement uncertainty and have been obtained from the diagonal of the Fisher matrix supplied by the WMAP team.
