Notes.

(a)

Best estimate cluster redshift – photometric redshift unless multiple corroborating spectroscopic redshifts are available.

(b)

We detect multiple structures with the red-sequence analysis for JKCS 041. However, we are unable to separate the X-ray emissions from the different structures and therefore give upper limits to the X-ray properties based on taking the entire X-ray emission for each.

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.
