Comparison of ΛCDM+CIP, ΛCDM+AL, and ΛCDM+AL+CIP models with various Planck datasets, when using the baseline Plik likelihood at high ℓ.
|Data and model||AL||AL||Δχ2||lnB|
Notes. The first two columns (“Constraints”) are the 68% CL ranges or the 95% CL upper bounds on (highlighted in bold for ΛCDM+CIP) and AL. The remaining columns give the best-fit pameter values, and the difference of the best-fit χ2 and the difference of the log of the Bayesian evidence with respect to the pure adiabatic ΛCDM model. A negative Δχ2 means that the quoted model fits the data better than ΛCDM, while a positive lnB means that the Bayesian model comparison favours the quoted model, when adopting the uniform priors and 0.3 ≤ AL ≤ 1.7.
