Notes. Forecasted constraints on RSD and AP parameters (mean values with 68% confidence intervals) from VIDE voids in the Euclid Flagship mock catalog (top rows). Results are given in four redshift bins with minimum, maximum, and mean void redshift Zmin, Zmax, 
, and large-scale galaxy bias b. All uncertainties correspond to one octant of the sky, but the expected precision from the full Euclid footprint is a factor of about 
higher. The bottom rows show more optimistic constraints after performing a calibration of the nuisance parameters in the model.
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.
