Catalog of Galaxies and Clusters of Galaxies
(CGCG, Zwicky Catalog)
(list of galaxies/clusters assembled in 1960s)
The Catalog of Galaxies and Clusters of Galaxies
(aka Zwicky Catalog, and abbreviated CGCG or sometimes ZC)
is such a list published by Fritz Zwicky
in the 1960s, with more than 29000 galaxies and 9000 galaxy clusters,
identified in the Palomar Observatory Sky Survey (POSS) plates.
Since publication, the catalog has been updated with
corrections and it remains in use for research,
such as selecting samples for study.
The Updated Zwicky Catalog (UZC) is a 1990s
update, using newer observations to correct data
and add precision.
