Description
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
