This catalog contains sources found at 4800 MHz (lambda = 6 cm) by combining data from various Australia Telescope Compact Array (ATCA) projects that covered the SMC. Some 601 sources have been detected at 6 cm in the new high-sensitivity and resolution radio-continuum image of the SMC from Crawford et al. (2011, SerAJ, 183, 95). The 6 cm map has a resolution of 30 arcseconds, and a sensitivity of 0.7 mJy/beam. The field size of the image used in this study covered from 00<sup>h</sup> 26<sup>m</sup> to 01<sup>h</sup> 28<sup>m</sup> in RA (J2000.0) and from -70<sup>o</sup> 29' to -75<sup>o</sup> 29' in Dec (J2000.0). The MIRIAD task 'imsad' was used to detect sources in the 6 cm image, requiring a fitted Gaussian flux density > 5 sigma (3.5 mJy). All sources were then visually examined to confirm that they are genuine point sources, excluding extended emission, bright side lobes, etc. This table was created by the HEASARC in September 2014 based on CDS Catalog J_other/Ser/184.93/ file tablea2.dat.
