cds-question@unistra.frradio-sourcessurveysThe 7C survey of radio sources is being made with the Cambridge Low-Frequency Synthesis Telescope at 151MHz, with an angular resolution of 70x70cosec{delta}.arcsec^2^. We present the results from one part of of this survey covering 0.144sr in two areas of sky centred at RA=10h28min, DE=41{deg} and RA=06h28min, DE=45{deg} and reaching a limiting flux density of 50mJy. A list of the positions, flux densities and angular sizes of 4723 sources is presented; the position errors are in the range 1-3arcsec for sources with flux densities greater than 500mJy, and the flux density errors are typically 18mJy. About 10 per cent of the sources have apparent angular sizes greater than 60arcsec. The derived source counts are as accurate as those presently available at 405 and 1400MHz and show similar behaviour; in particular the convergence slopes are the same. The median spectral index between 151 and 408MHz remains constant at ~0.9 between 10 and 0.5Jy at 151MHz.1990MNRAS.246..110Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/246/110CatalogResearchIsServedByTAP VizieR generic serviceIsPreviousVersionOfVIII/84IsServedByConesearch servicerelated-toVIII/84 : A final non-redundant catalogue for 7C 151-MHz survey (Hales+ 2007)J/A+AS/110/419 : 7C survey of radio sources (Visser+, 1995)J/MNRAS/282/779 : 7C 151-MHz survey of region 9-16h 20-35deg (Waldram+ 1996)J/MNRAS/294/607 : 7C(G) 151MHz survey of the Galactic plane (Vessey+ 1998)J/MNRAS/298/637 : 7C 151MHz survey of 3 regions (Pooley+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/246/110https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/246/110http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/246/110https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/246/110https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/246/110http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/246/110GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/246/110/tablea1 (Catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/246/110/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/246/110/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/246/110/tablea1?GETtext/xml+votable180.050000true87.394223350.12932760.0055555555555555563/83 4/327 331 344 346 347 356 357 359 365 368 369 370 422 423 425 426 427 428 429 430 434 5/341 343 349 351 373 375 1302 1303 1305 1306 1307 1317 1318 1319 1321 1352 1354 1355 1380 1382 1383 1413 1433 1435 1457 1468 1484 1504 1679 1683 1724 1760 6143 6/1361 1524 5181 5182 5183 5197 5199 5201 5203 5204 5206 5207 5217 5218 5219 5261 5262 5263 5265 5266 5267 5281 5292 5293 5295 5384 5386 5387 5412 5414 5415 5434 5435 5524 5526 5527 5608 5610 5648 5649 5651 5660 5661 5663 5728 5729 5731 5736 5737 5739 5825 5837 5839 5861 5876 5877 5878 5880 5881 5940 5941 5942 5944 5945 5946 5952 5954 5960 5962 6020 6021 6022 6024 6025 6026 6711 6715 6731 6746 6747 6750 6751 6797 6798 6799 6900 6960 6962 6963 7044 7048 24571https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/246/110?format=asciiRadiodefaultJ/MNRAS/246/110/tablea1CatalogueRAB1950Right ascension (B1950)recnoRecord number assigned by the VizieR team.
