cds-question@unistra.frCompact Steep Spectrum (CSS) and Gigahertz Peaked Spectrum (GPS) sources are classes of compact, powerful, extragalactic objects. These sources are thought to be the earliest stages in the evolution of radio galaxies, capturing the ignition (or, in some cases, re-ignition) of the active galactic nucleus. As well as serving as probes of the early stages of large-scale radio sources, these sources are good, stable, amplitude calibrators for radio telescopes. We present an unbiased flux density limited (>1.5Jy at 2.7GHz) catalogue of these objects in the Southern hemisphere, including tabulated data, radio spectra, and where available, optical images and measurements. The catalogue contains 26 sources, consisting of two new candidates and 15 known CSS sources, and nine known GPS sources. We present new Australia Telescope Compact Array (ATCA) data on 10 of these 26 sources, and data on a further 42 sources which were excluded from our final sample. This bright sample will serve as a reference sample for comparison with subsequent faint (mJy level) samples of CSS and GPS candidates currently being compiled.2011MNRAS.416.1135Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/416/1135CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/15 : Parkes Radio Sources Catalogue (PKSCAT90) (Wright+ 1990)VIII/16 : Molonglo Reference Catalogue of Radio Sources (Large+ 1991)VIII/38 : Parkes-MIT-NRAO 4.85GHz (PMN) Surveys (Griffith+ 1993-96)VIII/42 : Texas Survey of radio sources at 365MHz (Douglas+ 1996)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/70 : Sydney University Molonglo Sky Survey (SUMSS) (Mauch+ 2003)VIII/79 : The VLA Low-frequency Sky Survey at 74MHz (Cohen+ 2007)J/MNRAS/384/775 : Bright Source Sample of AT20G Survey (Massardi+, 2008)J/MNRAS/402/2403 : Australia Telescope 20GHz Survey Cat., AT20G (Murphy+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/416/1135https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/416/1135http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/416/1135https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/416/1135https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/416/1135http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/416/1135GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/416/1135/table7 (Summary of C1813 data (ATCA, see table2))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/1135/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/1135/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/1135/table7?GETtext/xml+votable180.050000true2.7188322-41.88633080.005555555555555556Cone search capability for table J/MNRAS/416/1135/table8 (Table of data for CSS and GPS candidates and sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/1135/table8?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/1135/table8?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/1135/table8?GETtext/xml+votable180.050000true6.1789583-42.03430560.005555555555555556Cone search capability for table J/MNRAS/416/1135/sample (Final sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/416/1135/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/416/1135/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/416/1135/sample?GETtext/xml+votable180.050000true6.1789583-42.03430560.0055555555555555566/16496 16509 16722 16764 16900 17443 17488 17544 17719 17979 18017 18065 18784 20503 22659 24615 24902 24936 25743 27138 29715 29963 30010 31029 32892 33010 33229 34441 34648 34650 34669 35217 35383 35427 35482 35491 35568 35666 35685 36417 36431 36595 39079 39087 41057 42249 43257 43566 43672 44523 45109 45763 45805 45961 46273 46444 46512 46654 47022 47107 47512 47620 47849 48256 48501 48529 48614 487244.903291545219051e-26 1.325213914061602e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/416/1135?format=asciiRadiodefaultJ/MNRAS/416/1135/table7Summary of C1813 data (ATCA, see table2)e_S1.4rms uncertainty on S1.4Jystat.errorfloatrecnoRecord number assigned by the VizieR team.
