cds-question@unistra.frradio-galaxiesinterferometryThis catalog contains compact core fluxes for a list of 175 southern radio galaxies, measured with the Parkes-Tidbinbilla Interferometer (PTI, Norris et al. 1988ApJS...67...85N) on a single 275 km baseline at 2.3 GHz and 8.4 GHz. The sample consists of large angular size ( > 0.5 arcmin) steep spectrum sources from Jones & McAdam (1992ApJS...80..137J) observed to determine the fraction of flux contained in compact (VLBI-scale) cores. Of the 172 sources observed at 2.3 GHz (100 milliarcsec fringe spacing), 63 had cores detected and upper limits were determined for the remaining 109. Of the 88 sources observed at 8.4 GHz (30 milliarcsec fringe spacing), 38 had cores detected and 50 have upper limits. A comparison of the detections and upper limits at the two frequencies shows that the cores have flat or inverted spectra. The core fluxes quoted here may vary by around 20 % if there is structure on the scale of the fringe spacing and the cores are probably intrinsically variable.1994MNRAS.268..602Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/268/602CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/268/602https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/268/602http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/268/602https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/268/602https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/268/602http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/268/602GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/268/602/pti_core (Compact Radio Cores in Radio Galaxies (Dec < -30d))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/268/602/pti_core?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/268/602/pti_core?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/268/602/pti_core?GETtext/xml+votable180.050000true1.560979-83.0999030.0055555555555555566/20483 20527 24614 24710 32815 32898 33022 33065 33083 33143 33234 33291 33316 33337 33440 33460 33505 33731 33798 33816 33968 34007 34086 34090 34104 34233 34293 34303 34311 34327 34441 34463 34493 34513 34535 34545 34648 35026 35040 35056 35097-35098 35113 35125 35353 35398 35434 35447 35608 37189 37191 37277 37308 37330 37412 37441 37546 37687 37734 37776 37987 38174 38260 38364 38376 38558 38585 38605 38624 38791 38793 38819 38935 38937 38963 38974 39012 39043 39077 39087 39144 39175 39181 39368 39492 39614 39715 39722 39725 39961 39982 40105 41051 41414 41418 41423 41434 41477 41510 41584 41615 41831 41870 41928 41943 41995 42003 42060 42080 42235 42581 42700 42743 43010 43233 43259 43262 43285 43389 43417 43451 43461 43471 43590 43600 43646 43806 43913 43925 44068 44129 45197 45263 45283 45339 45418 45446 45522 45525 45793 45823 45862 45883 45908 45912 45915 45961 45984-45985 46095 46101 46146 46268 46348 46442 46644 46715 46801 46911 47151 47174 47270 47393 47462 47533 47744 47810 47873https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/268/602?format=asciiRadiodefaultJ/MNRAS/268/602/pti_coreCompact Radio Cores in Radio Galaxies (Dec < -30d)recnoRecord number assigned by the VizieR team.
