Jansky Very Large Array. We describe the reduction and cataloguing process, which yielded an image with 8 arcsec resolution and instrumental noise of \\sigma$_{\\rm n}$=1.0 \\mu Jy beam$^{-1}$ rms (before primary beam corrections) and a catalogue of 558 sources detected above 5\\sigma$_{\\rm n}$. We include details of how we estimate source spectral indices across the 2-GHz VLA bandwidth, finding a median index of -0.76$\\pm$0.04.
