Spectroscopic Redshifts of 1,561 Galaxies in 12 Merging Galaxy Clusters from the X-SORTER Survey

Dataset description This dataset contains spectroscopic redshifts from Keck/DEIMOS observations of galaxies associated with candidate merging galaxy clusters identified in the X-SORTER (X-ray Survey Of meRging clusTErs in Redmapper) project. The catalog contains 1,561 spectroscopic redshifts across 12 galaxy clusters, with redshifts spanning approximately 0.07-0.96. Each catalog entry includes: cluster name R.A. (deg) Dec (deg) spectroscopic redshift 1-sigma uncertainty The catalog is provided in both AAS Machine Readable Table (MRT) and CSV formats. This catalog accompanies: Hopp et al.
