Notes. Column (1): Planck source name. Columns (2), (3): signal-to-noise ratio of the Planck cluster candidate detection with the MMF3 algorithm in the v4.1 Planck-HFI maps, number of methods blindly detecting the candidate. Column (4): quality grade of the SZ detection (A is best). Columns (5) and (6): right ascension and declination of the Planck source (J2000). Columns (7)–(10): XMM-Newton observation identification number, filter used, on-source exposure time with the epn camera and fraction of useful time after cleaning for periods of high background due to soft proton flares (emos and epn camera, respectively). Asterisked objects denote observations affected by a high background level. Column (11): confirmed clusters are flagged.

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.
