VizieR Online Data Catalog: Bayesian group finder applied to the 2MRS data (Tempel+, 2018)
Abstract
The catalogue of galaxy groups and clusters consists of two tables. The first table lists galaxies that were used to generate the group catalogue, the second describes the group properties. Galaxy data are based on the 2MRS (Huchra et al., 2012, Cat. J/ApJS/199/26), downloaded from the extragalactic distance database (EDD2; Tully et al., 2009AJ....138..323T). This data set includes galaxies brighter than 11.75mag in the Ks band. For group extraction, the galaxy sample was restricted to galaxies closer than 300Mpc. Due to the probabilistic nature of the group finder algorithm, probabilities that a galaxy belongs to a specific group or whether the galaxy is a field galaxy were derived. The individual probabilities are presented in the galaxy catalogue.
