Notes. The columns give: (1) morphological type; (2) number and percentage of galaxies with I> 2 and I< 0.5 for Ferguson’s IP in the data and for the randomized clusters; (3) the same for substructure IP and (4) for the group IP. The percentages for the pseudo-clusters are mean values. The standard deviations 
are similar for all types and amount to 
for IFerg> 2, and to 
for Isub> 2 and Igroup> 2. For the free members the values are 
for the IP of F92, 
for the substructure IP and 
for the group IP.
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.
