J/ApJ/vol/page Local Group dSph radio survey with ATCA (Regis+, 2014) ================================================================================ Local Group dSph radio survey with ATCA (I): Observations and background sources Regis M., Richter L., Colafrancesco S., Massardi M., de Blok W.J.G., Profumo S., Orford N. = (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Galaxies, radio ; Radio continuum Keywords: catalogues - galaxies: dwarf - radio continuum: galaxies Description: We present a catalogue of radio sources detected in the fields of six dwarf spheroidal galaxies of the Local Group, which are Carina, Fornax, Sculptor, BootesII, Segue2, and Hercules. Observations were performed during July/August 2011 with the six 22-m diameter Australia Telescope Compact Array antennae operating at 16 cm wavelength. We mosaiced a region of radius of about one degree around the first three dwarfs, and of about half of degree around the last three dwarfs. The rms noise level is below 0.05 mJy. The restoring beams FWHM ranged from 4.2 x 2.5 arcseconds to 30.0 x 2.1 arcseconds in the most elongated case. The catalogue includes different parameters describing 1835 entries which, in our classification, correspond to 1392 sources. See the above publication for more details.

Note (2): Peak flux densities are not corrected for possible systematic effects, which are estimated to be negligible (see discussion in the publication). Note (3): Errors on integrated flux density are obtained summing in quadrature the local rms, the fit error, and a 5% of the flux density (to account for possible inaccuracy in the calibration model and process, especially due to RFI). Note (4): When F/Fp<1.3, the source is not successfully deconvolved and these values should not be considered. Note (5): Flag for multiple component sources: S = single component source; M = multiple component source, followed by a number, identifying the multiple source to which the component belongs, and a letter identifying the field (a=Carina, b=Fornax, c=Sculptor, d=BootesII, e=Hercules, f=Segue2). * = Source present in the tapered map, but not in the un-tapered map. In this case, all the properties in the other columns are derived from the tapered map. -------------------------------------------------------------------------------- ================================================================================ (End) Marco Regis [University of Turin and INFN, Italy] 01-Jan-2003
