Wideband Mosaic Imaging with the VLA - quantifying faint source imaging   accuracy
  A large number of deep and wide-field radio interferometric surveys are being designed to measure accurate statistics of faint source populations. Most require mosaic observations, and expect to benefit from the sensitivity provided by broad-band instruments. In this paper, we present preliminary results from a comparison of several wideband imaging methods in the context of how accurately they reconstruct the intensities and spectral indices of micro-Jy level sources.
