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.
