VizieR Online Data Catalog: The 3C and 3CR Catalogues (Edge+ 1959-1962)
Abstract
The 3C Catalog is the result of observations with the Cambridge four-element interferometer at a frequency of 159MHz, and contains 471 sources between declinations -22 and +71degrees, with a flux density larger than 8Jy.
The Revised version of the 3C (3CR) is based on new observations at a frequency of 178MHz, and represents a survey of all sources North of -05degrees with a flux density brighter than 9Jy, except in the areas near the ridge of galactic emission. The original numbering system has been preserved. (2 data files).- Publication:
