ASTRONOMICAL CATALOG

An 'astronomical catalog' or 'catalogue' is a list or tabulation of astronomical objects, typically grouped together because they share a common type, morphology, origin, means of detection, or method of discovery. Astronomical catalogs are usually the result of an astronomical survey of some kind.
