Notes. We show the approximations employed, the highest kmax with its associated value of the reduced χ2 and best-fitting model parameter. The upper table shows the ELEPHANT fits, the lower table the DEMNUni fits. We note that b2 and N are normalised differently in the different models, so they are not expected to have similar values. b1, b2 and b𝒢2 are dimensionless. N has dimensions h−3 Mpc3. σv and 
have dimensions h−1 Mpc and h−2 Mpc2 respectively.
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.
