Notes. Each cluster shows a significant overdensity of the galaxies considered.


Raw numbers, neither corrected for incompleteness, nor background subtracted.


After subtracting the background from the CFHTLS fields, matched in depth, for the same redshift and matched in unmasked area. Poisson errors, which are given, dominate over the field-to-field variance that we measure from the four spatially-independent CFHTLS fields.

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.
