VizieR Online Data Catalog: X-ray luminosities of SDSS DR7 clusters from RASS (Wang+, 2014)
Abstract
The optical data used in our analysis are taken from the SDSS galaxy group catalogues of Yang et al. (2007ApJ...671..153Y), constructed using the adaptive halo-based group finder of Yang et al. (2005MNRAS.356.1293Y), here updated to DR7. The parent galaxy catalogue is the New York University Value-Added Galaxy Catalog (NYU-VAGC; Blanton et al. 2005AJ....129.2562B) based on the SDSS DR7 (Abazajian et al. 2009ApJS..182..543A), which contains an independent set of significantly improved reductions.
