cds-question@unistra.frsurveysradio-galaxiesh-i-line-emissionradial-velocityWe have carried out an extremely long integration time (9000s/beam) 21-cm blind survey of 60deg^2^ in Centaurus using the Parkes multibeam system. We find that the noise continues to fall as sqrt(t_obs_) throughout, enabling us to reach an H I column-density limit of 4.2x10^18^cm^-2^ for galaxies with a velocity width of 200km/s in the central 32deg^2^ region, making this the deepest survey to date in terms of column density sensitivity. The H I data are complemented by very deep optical observations from digital stacking of multi-exposure UK Schmidt Telescope R-band films, which reach an isophotal level of 26.5Rmag/arcsec^2^ (27.5Bmag/arcsec^2^). 173 H I sources have been found, 96 of which have been uniquely identified with optical counterparts in the overlap area.2003MNRAS.346..787Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/346/787CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/73 : HI Parkes All Sky Survey Catalogue (HIPASS) (Meyer+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/346/787https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/346/787http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/346/787https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/346/787https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/346/787http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/346/787GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/346/787/table4 (H I properties of HIDEEP galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/346/787/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/346/787/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/346/787/table4?GETtext/xml+votable180.050000true201.438333-28.8155560.0055555555555555564/2742 5/10957 10962 10992-10993 6/43799 43805 43807 43825-43827 43835-43837 43843 43852 43854-43855 43888 43890 43896 43898 43900 43902 43925 43977 43980 43982-43984 43986-43988 43992https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/346/787?format=asciiOpticalRadiodefaultJ/MNRAS/346/787/table4H I properties of HIDEEP galaxiesrecnoRecord number assigned by the VizieR team.
