cds-question@unistra.frgalaxy-clustersactive-galactic-nucleiradio-galaxiesredshiftedWe present unequivocal evidence for a huge (~80x100x100Mp^3^) superstructure at redshift z=0.27 in the three-dimensional distribution of radio galaxies from the Texas-Oxford NVSS Structure 08h region (TONS08) sample, confirming tentative evidence for such a structure from the 7C redshift survey (7CRS). A second, newly discovered superstructure is also found less securely at redshift 0.35 (of dimensions ~100x100x100Mpc^3^). We present full observational details on the TONS08 sample which was constructed to probe structures in the redshift range 0<z<0.5 by matching NVSS sources with objects in APM catalogues to obtain a sample of optically bright (E~R<=19.83), radio-faint (1.4GHz flux density S_1.4_>=3mJy) radio galaxies in the same 25deg^2^ area as part II of the 7CRS.2003MNRAS.344..283Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/344/283CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/71 : The FIRST Survey, version 03Apr11 (Becker+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/344/283https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/344/283http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/344/283https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/344/283https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/344/283http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/344/283GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/344/283/table2 (A summary of key information on the TONS08 sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/344/283/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/344/283/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/344/283/table2?GETtext/xml+votable180.050000true122.636458328.34291390.0055555555555555565/1212-1213 1215 1256 6/4815 4822 4825-4827 4829-4831 4837 4857 4859 5032 6228https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/344/283?format=asciiOpticalRadiodefaultJ/MNRAS/344/283/table2A summary of key information on the TONS08 sampleTONS08TONS08 numbermeta.id;meta.mainintm_TONS08[ab] Multiplicity index on TONS08 (1)(2)meta.code.multipcharn_TONS08[*] *: Note on TONS08 288 (3)meta.notecharTelTelescope (4)meta.id;instr.telcharDateObservation datetime.epochnullableDate2Second observation date when intervaltime.epochnullableRAJ2000Right ascension (J2000) (1)pos.eq.ra;meta.mainDEJ2000Declination (J2000) (1)pos.eq.dec;meta.mainSNVSSIntegrated radio flux density in the NVSS (Cat. <VIII/65>) catalog (1.4GHz)mJyphot.flux.density;em.radio.750-1500MHzfloatSFIRST?
