4C catalogue of radio sources


Table name: 	4C
Records:  	4842
Spectral Band: 	RADIO
Kind of Object: Radio Sources
Coordinates: 	B1950



The catalogue contains the results of a survey of radio sources in the range of declinations -7 to +80 deg using the interferometric radio telescope of the Mullard Radio Astronomy Observatory (Cambridge, UK). The observations, at a frequency of 178 MHz, employed the technique of aperture synthesis and permitted the detection of sources having a flux density S(178) < 2 Jy with a positional accuracy, for the weaker sources, of about 0.35 arcmin in right ascension and 2.5 arcmin in declination
