The image has a resolution of 5.6x5.1arcsec, a radius of $2.05^\\circ$ and a central noise of ~0.2mJy\\beam. Both the resolution and noise of the image are an order of magnitude better than what was previously available at this frequency and will serve as a valuable addition to the already extensive multiwavelength data that are available for this field. The final source catalogue contains 1370 sources and has a median 325 to 1400MHz spectral index of -0.72.
