VizieR Online Data Catalog: SPT-selected galaxy clusters X-ray analysis (Sanders+, 2018)

Our sample of systems (listed in table A1) includes the sample of SPT clusters of Bleem et al. (2015ApJS..216...27B, Cat. J/ApJS/216/27) marked as having X-ray data, excluding SPT-CLJ0037-5047 which has low signal to noise. We also include two further systems in that paper which also have X-ray data and were examined in McDonald et al. (2013ApJ...774...23M, Cat. J/ApJ/774/23, hereafter MD13), SPT-CLJ0236-4938 and SPT-CLJ0310-4647. We do not include SPT-CLJ0446-5849 which has low signal to noise. We also exclude SPT-CLJ0330-5228 and SPT-CLJ0551-5709 which are contaminated (McDonald et al., 2014ApJ...794...67M). As MD13 describes, their sample consists of strongly detected clusters by SPT, with SPT detection significances between 5.7 and 43. The mass range of M₅₀₀ is between 2x10¹⁴ and 2x10¹⁵M_ȯ, while the redshift range is between 0.3 and 1.2. At the median redshift, the sample should be around 50 per cent complete at M₅₀₀=4x10¹⁴, increasing to 100 per cent at 6x10¹⁴M_ȯ. We make use of any new public observations from the Chandra archive, where possible.

The surface-brightness profiles in multiple X-ray bands were fitted using a new hydrostatic modelling code, MBPROJ2, to obtain dark-matter and thermodynamic profiles.
