Abstract:
The Cambridge Low Frequency Synthesis Telescope has been used at 151
MHz to survey a region of 1393 square degrees, in the range RA 9h to
16h, Dec 20deg to 35deg, with an angular resolution of
108x108cosec(dec) arcsec2. The rms noise on the maps is in general
∼35-55 mJy/beam but varies considerably and exceeds this in some
areas. We have extracted sources with signal-to-noise ratio > 5.5, a
total of 5526, and present a catalogue of their positions and flux
densities.
