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) arcsec^2^. 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.
