Notes. Initial values and priors of the 13 free parameters describing our cluster model in the MCMC fit. The last parameter is also free and accounts for the level of uniform background in the 0.4−1 keV image.
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.
