Radio observations of the Hubble Deep Field-South region. III. The 2.5, 5.2, and 8.7 GHz catalogs and radio source properties. Huynh M.T., Jackson C.A., Norris R.P. <Astron. J., 133, 1331-1344 (2007)> =2007AJ....133.1331H
ADC_Keywords: Surveys ; Radio sources ; Active gal. nuclei Keywords: catalogs - radio continuum: galaxies - surveys Abstract: Deep radio observations of a wide region centered on the Hubble Deep Field-South have been performed, providing one of the most sensitive sets of radio observations acquired on the Australia Telescope Compact Array to date. A central rms of ∼10uJy is reached at four frequencies (1.4, 2.5, 5.2, and 8.7GHz). In this paper the full source catalogs from the 2.5, 5.2, and 8.7GHz observations are presented to complement Paper II (Huynh et al., 2005, Cat. J/AJ/130/1373) in this series, along with a detailed analysis of image quality and noise. We produce a consolidated catalog by matching sources across all four frequencies of our survey. Description: Observations and data reduction that are discussed in detail in Paper I (Norris et al., Cat. J/AJ/130/1358). File Summary:

Note (1): These are low SNR (3-5.5σ) sources with a priori 1.4GHz positions. The Seq numbering for the supplementary catalogs starts from the end of the main catalogs. Note (2): Not corrected for the systematic effects described in Section 3. ATCA fluxes are generally estimated to be accurate to about 10%. Note (3): Only given for successfully deconvolved sources. Note (4): Measured from N through E. Only given for successfully deconvolved sources. Note (5): Calculated as IMSAD fitted peak/σlocal. Note (6): 2 = poor integrated flux density, see Section 4 for more details.

Note (1): Source coordinates are obtained from: L = 1.4GHz observation S = 2.5GHz observation C = 5.2GHz observation X = 8.7GHz observation Note (3): Where S∝να. The spectral indices are calculated from flux densities measured on low resolution images, as described in Section 7. Note (4): Type of source as follows: AGN = AGN with flat or inverted spectrum (S1.4<0.5mJy and α>0 or S1.4>0.5mJy and α>-0.3) GPS = GigaHertz Peaked Spectrum, for AGN where the spectrum is inverted between 1.4 and 2.5, but steep at higher frequency
