Notes. The values are obtained by fitting mock Planck and Euclid WL data to either HMCode without baryonic feedback or Halofit without PKequal non-linear corrections. The last row shows Δχ2. By construction χ2 = 0, unless the configuration of the MCMC sampling does not match the one used to create the fiducial synthetic dataset. The number of degrees of freedom in this case is 11 (the number of free parameters in the model; Ωm, 0 and σ8 are derived parameters), which enables one to compare Δχ2 to the corresponding confidence interval.
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.
