Notes. Only the sources for which we detect an IR excess are shown. An extended version of this table including all the photometric bands analysed in this work for all the members of IC 4665 is available at the CDS. ( * )Measurement filtered (see Sect. 2.2).

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.
