cds-question@unistra.frradio-continuum-emissionsurveysVLA observations at 4.9GHz are given for 144 steep-spectrum 4C sources whose declinations are between -4{deg} and +4{deg} and whose angular sizes are smaller than 30arcsec. The paper contains 150 maps (VLA and 6 MERLIN observations at 1420 or 1658MHz) which are not included here.1999A&AS..134..401Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/134/401CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-to1996ApJS..107..175R : VLA imaging of a sample of steep-spectrumhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/134/401https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/134/401http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/134/401https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/134/401https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/134/401http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/134/401GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/134/401/table2 (Positions and fluxes observed with VLA)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/134/401/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/134/401/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/134/401/table2?GETtext/xml+votable180.050000true3.29673810.8639250.0055555555555555566/6 4107 8216 12306-12307 12322 17401-17402 17629 17658 17718 17723 17740 17802-17803 17834 17853 17868 18000 18006 18009 18039 18044 18051 18063 18077 18079 18093 18112 18186 18196 18670 18680 18684 18750 18808 18812 18815 18845 18851 18861-18862 18870 18878-18879 18890 19008 19045 19047 19060 19065 19071 19124 19141 19150 19172 19202 19204 19211 19470 21814 21839 21869 21877 21957 22878 22926 23069 23086 23112 23127 23153 23162-23163 23214 23302 26873 27019 27022-27023 27044 27058 27062 27165 27209 27217 27233 27244 27253 27285 27310 27321 27330 27392 27408 30010 30038 30059 30062 30076 30096 30132 30943 30962-30963 31005 31025 31032 31055 31100 31107 31111 31122 31126 31134 31141 31152 31168 31181 31291 31296-31297 31327 31343-31344 31367 31400 31405 31421 31428 31458 31776 40947 40959 45020 45046 491363.220269899637266e-24 3.220269899637266e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/134/401?format=asciiRadiodefaultJ/A+AS/134/401/table1*Objects observed, together with the geometry of the restoring beam.recnoRecord number assigned by the VizieR team.
