Description:
The Cambridge Low Frequency Synthesis Telescope has been used at 151MHz to
survey a region of 418 square degrees centred at RA=17h, DE=65deg, which
includes the North Ecliptic Cap. The resolution is 70x70"cosecδ and
the rms noise on the maps is 25mJy/beam. We present positions and flux
densities for 2702 sources which have a signal to noise ratio >5.5 and radio
maps of 37 selected extended sources.
