摘要

While analyzing individual sources in these images of the LMC (Dickel et?al. 2005), we have determined that in an attempt to obtain the best looking results, we overCLEANed (H?gbom 1973) the images from the ATCA data too close to the noise level. This process smoothed the background but resulted in a loss of flux densities recorded for the shortest spacings of the array. To correct this, we have reCLEANed the images with a cutoff of 2 mJy, about six times the theoretical noise level. The images look noisier but appear to give the correct flux densities for known sources. The new corrected images are available in FITS format from the public Web site of the Australia Telescope National Facility at http://www.atnf.csiro.au/research/lmc_ctm.
