Notes. For each cluster, we give the name (1), coordinates (2,3), redshift (4), measured temperature (5), measured metallicity (*: fixed metallicity) (6), X-ray luminosity in the [0.5-2] keV band within R₅₀₀ (7), estimated radius (no uncertainties provided) (8), and the reduced chi-square of the pointing background level fit (9). A few measurements are not available (see Table 2), and they appear as blank fields in the table. Only part of the table is presented here. The full table is available at the CDS.

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.
