Notes. The 10 targets of the pilot programme are listed first. Column (1): Planck source name. Asterisked objects denote sources that were found to be multiple systems in X-rays. Column (2): signal-to-noise ratio of the detection of the Planck cluster candidate in the version of the Planck-HFI maps available for each programme. Columns (3) and (4): right ascension and declination of the Planck source (J2000). Columns (5)–(8): 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, see also Sect. 2.5). Column (9): confirmed clusters are flagged. Those included in the ESZ sample (Planck Collaboration 2011d) are also identified.
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.
