cds-question@unistra.frgalaxiescatalogsradio-sourcesAt the faintest radio flux densities (S1.4<10mJy), conflicting results have arisen regarding whether there is a flattening of the average spectral index between a low radio frequency (325 or 610MHz) and, for example, 1.4GHz. We present a new catalogue of 843-MHz radio sources in the European Large Area ISO Survey-South 1 field, which contains the sources, their Australia Telescope Large Area Survey (ATLAS) counterparts and the spectral index distribution of the sources as a function of flux density.2012MNRAS.421.1644Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/421/1644CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/290 : SWIRE Photometric Redshift Catalogue (Rowan-Robinson+, 2008)J/MNRAS/351/1290 : ELAIS: final band-merged catalogue (Rowan-Robinson+, 2004)J/AJ/135/1276 : ATLAS radio observations of ELAIS-S1 (Middelberg+, 2008)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/421/1644https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/421/1644http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/421/1644https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/421/1644https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/421/1644http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/421/1644GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/421/1644/table1 (843MHz Molonglo Observatory Synthesis Telescope (MOST) ATLAS catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/421/1644/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/421/1644/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/421/1644/table1?GETtext/xml+votable180.050000true6.84300417-43.244661110.0055555555555555565/8847 8868 6/35379 35382 35385-35387 35476 35478 35481 354845.585776613014535e-25 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/421/1644?format=asciiRadiodefaultJ/MNRAS/421/1644/table1843MHz Molonglo Observatory Synthesis Telescope (MOST) ATLAS cataloguerecnoRecord number assigned by the VizieR team.
