VizieR Online Data Catalog: Stellar mass as a galaxy cluster mass proxy (Palmese+, 2020)

The DES is an optical-to-near-infrared survey that imaged 5000deg² of the South Galactic Cap in the grizY bands over 575 nights spanning almost 6yr. The survey was carried out using a ~3deg² CCD camera (the DECam, see Flaugher et al. 2015AJ....150..150F) mounted on the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory (CTIO) in Chile. The data used here come from the first year of observations (2013 September-2014 February, Diehl et al. 2014SPIE.9149E..0VD) and cover 1839deg² with up to four passes per filter. The data are available at http://des.ncsa.illinois.edu/releases/y1a1.

The cluster catalogue used here is the cosmology Y1 redMaPPer catalogue v6.4.14 with richness λ>5, which consists of 87297 clusters. This sample is then matched to archival X-ray observations from Chandra and X-ray MultiMirror Mission (XMM). We use these X-ray data to measure an X-ray temperature at the position of redMaPPer clusters, rather than cross-matching with existing X-ray cluster catalogues.

While the cluster catalogue is based on Y1 data, the photometry comes from the deeper Year 3 data (Abbott et al. 2018ApJS..239...18A, Cat. II/357). The photometry is the result of the Multi-Object Fitting (MOF) pipeline that uses the NGMIX code.
