Notes. The information given in each column is as follows: 2) indicates the Hα flux threshold for 100% DIG dominance; 3) indicates the exponent, β, of each model; 4) shows the percentage of DIG fibres with regard to all considered fibres for each galaxy; 5,6,7) show the percentage of star-forming, composite, and AGN fibres in the sample, respectively; 8) denotes the total number of fibres used for the BPT classification.
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.
