Left: Comparison of the best‐fit ΛCDM model of § 3 based on WMAP data only to the 2dFGRS power spectrum (Percival et al. 2001). The bias parameter for the best‐fit power‐law ΛCDM model is 1.0, corresponding to a best‐fit value of ﹩\beta =0.45﹩. Right: Comparison of the best‐fit power‐law ΛCDM model of § 3 to the power spectrum at ﹩z=3﹩ inferred from the Lyα forest data. The data points have been scaled downward by 20%, which is consistent with the 1 σ calibration uncertainty (Croft et al. 2002).
