Notes. Column (1): sample ID; Column (2): number of galaxies per sample; Column (3): range of angular separation of the fg–bg pairs; Column (4): mean angular separation of the fg–bg pairs within the θ range; Column (5): range of the impact parameter in kpc assuming zmed within the projected separation bin for conversion; Column (6): mean impact parameter within the θ range in kpc; Columns (7) and (8): redshift ranges and mean redshift of the foreground galaxies sample within their corresponding θ range, and Cols. (9) and (10): redshift ranges and mean redshift of the background galaxies sample within their corresponding θ range.
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.
