Notes. We also show the corresponding bounds on the derived parameters (here ns, dns/ dlnk, and r0.002 are derived from the numerically computed primordial spectra). All error bars are at the 95% CL. The effective χ2 value and Bayesian evidence logarithm (lnB) of model n are given relative to the model of next lowest order (n−1) (assuming flat priors for and in the range [−1,1 ]).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
