Catalog Service: Lyon Groups of Galaxies
Description
The catalog of nearby groups of galaxies was created from the sample of galaxies complete up to the limiting apparent magnitude Bo=14.0 with a recession velocity smaller than 5500km/s. Two methods were used in group construction: a percolation method derived from Huchra and Geller (1982ApJ...257..423H) and a hierarchical method initiated by Tully (1980ApJ...237..390T). The catalog presented here is a synthesized version of the two results.
