e/Lyons Groups of Galaxies

Information
has gloss	eng: Lyons Groups of Galaxies (or LGG) — catalog of nearby groups of galaxies that 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 ( ) and a hierarchical method initiated by Tully ( ). The catalog is a synthesized version of the two results.
