Notes. Each column represents a different subsample of CGs, while each row represents a different GG subsample (see Sect. 3.1 for a more detailed description of each subsample). Errors were computed with a bootstrap-resampling technique. For each GG subsample, we have included a second row with the expected percentage of embedded compact groups, which is computed considering the size of the GG subsample as the product of the total percentage, quoted in the first row, and the percentage of the GG sample that represents the corresponding subsample, quoted in the first column. OBS: Results obtained from the observational samples. SAM: Results obtained from the semi-analytical samples.
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.
