Lyons Groups of Galaxies
Lyons Groups of Galaxies (or LGG) is an
recession velocity smaller than 5,500 km/s. The catalogue was obtained from the Lyon-Meudon Extragalactic Database. Two methods were used in group construction: a percolation method derived from Huchra and Geller [1] and a hierarchical method initiated by R. Brent Tully.[2]
The catalog is a synthesized version of the two results.
The LGG includes 485 groups and 3,933 member galaxies.
