cds-question@unistra.frgalaxiesvisible-astronomyredshiftedspectroscopyx-ray-sourcessurveysgalaxy-clustersWe present the global group properties of two samples of galaxy groups containing 39 high-quality X-ray-selected systems and 38 optically (spectroscopically) selected systems in coincident spatial regions at 0.12<z<0.79. The total mass range of the combined sample is ~(10^12^-5)x10^14^M_{sun}_. Only nine optical systems are associable with X-ray systems. We discuss the confusion inherent in the matching of both galaxies to extended X-ray emission and of X-ray emission to already identified optical systems. Extensive spectroscopy has been obtained and the resultant redshift catalog and group membership are provided here. X-ray, dynamical, and total stellar masses of the groups are also derived and presented. We explore the effects of utilizing different centers and applying three different kinds of radial cut to our systems: a constant cut of 1Mpc and two r_200_ cuts, one based on the velocity dispersion of the system and the other on the X-ray emission.2012ApJ...756..139Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/756/139CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/268 : DEEP2 Redshift Survey, Data Release 4 (Matthews+ 2013)J/ApJ/751/50 : Cat. of galaxy groups from DEEP2 Redshift Survey (Gerke+ 2012)J/ApJS/184/218 : The zCOSMOS 10k-bright spectroscopic sample (Lilly+, 2009)J/ApJ/658/865 : Galaxy redshifts in X-ray-luminous groups (Jeltema+, 2007)J/ApJS/172/182 : XMM Clusters of galaxies in COSMOS field (Finoguenov+ 2007)J/A+A/461/397 : RASS-SDSS galaxy cluster survey.
