Abell Catalogue
The Abell catalog of rich clusters of galaxies is an all-sky catalog of 4,073 rich galaxy clusters of nominal redshift z <= 0.2. This catalog supplements a revision of George O. Abell’s original “Northern Survey” of 1958, which had only 2,712 clusters, with a further 1,361 clusters – the “Southern Survey” of 1989 – from those parts of the south celestial hemisphere that had been omitted from the earlier survey.

Famous quotes containing the word catalogue:
“Ay, in the catalogue ye go for men,
As hounds and greyhounds, mongrels, spaniels, curs,
Shoughs, water-rugs, and demi-wolves, are clept
All by the name of dogs.”
—William Shakespeare (15641616)
