cds-question@unistra.frradio-sourcesastronomical-object-identificationOptical identifications have been sought for 198 southern radio sources (73 in Paper I, 06h<RA(B1950)<18h and 125 in Paper II, 18h<RA(B1950)<06h) using new positions determined with the six-dish array of the Fleurs synthesis telescope. These sources constitute a complete sample drawn from the Parkes 2700-MHz catalogue. They are all flat-spectrum sources stronger than 0.25 Jy at 2700 MHz and lie between Dec(B1950) -80 and -50{deg}. Sources with |b|<5{deg} are not included. The new radio positions have standard deviations of about 1'' (2'' in Paper I, 1'' in Paper II) in right ascension and declination. The optical positions are with respect to the FK4 reference system as defined by the Perth catalogues and have position uncertainties of about 0.5arcsec. Magnitude estimates are on the J scale and are accurate to about 0.4mag for stellar-like objects and 0.5 to 1.0mag for galaxies. The sample is complete to the 22.5-mag limit of the SERC-J sky atlas. There are 198 sources in the complete sample. 31 sources (16%) show some radio structure with the 2'' beam. For the 175 unresolved sources, there are 124 QSOs (71%), 26 galaxies (15%) and 25 empty fields (14%) suggested.1987MNRAS.227..705Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/VIII/45CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/15 : Parkes Radio Sources Catalogue (PKSCAT90) (Wright+ 1990)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VIII/45https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VIII/45http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VIII/45https://vizier.cds.unistra.fr/viz-bin/votable?-source=VIII/45https://vizier.iucaa.in/viz-bin/votable?-source=VIII/45http://vizieridia.saao.ac.za/viz-bin/votable?-source=VIII/45GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table VIII/45/table2 (Radio and optical identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/VIII/45/table2?https://vizier.iucaa.in/viz-bin/conesearch/VIII/45/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/VIII/45/table2?GETtext/xml+votable180.050000true5.638125-51.88752780.005555555555555556Cone search capability for table VIII/45/table1 (Radio positions and optical identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/VIII/45/table1?https://vizier.iucaa.in/viz-bin/conesearch/VIII/45/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/VIII/45/table1?GETtext/xml+votable180.050000true5.6381057-51.88749940.0055555555555555566/32916 32961 32969 32979 33008 33043 33048 33049 33054 33057 33079 33086 33090 33098 33112 33116 33120 33123 33153 33155 33176 33191 33218 33238 33285 33286 33356 33357 33388 33398 33429 33430 33463 33468 33471 33549 33560 33570 33575 33626 33629 33679 33684 33711 33717 33720 33722 33740 33816 33825 33827 33829 33833 33845 33862 33879 33884 33951 33967 33973 34313 34866 34870 34871 34901 34911 34931 34938 34991 35016 35079 35082 36941 36968 36988 37030 37040 37047 37056 37062 37091 37104 37138 37141 37155 37156 37190 37191 37201 37203 37210 37217 37229 37254 37385 37416 37440 37450 37480 37512 37519 37526 37529 37531 37547 37557 37686 37690 37994 38005 38918 38932 38952 41043 41048 41051 41052 41059 41072 41080 41110 41184 41193 41208 41240 41262 41275 41310 41387 41390 41511 41524 41531 41543 41545 41568 41604 41607 41730 42012 42060 43528 45158 45159 45162 45164 45165 45176 45177 45178 45227 45259 45332 45358 45371 45393 45400 45409 45424 45434 45540 45558 45571 45614 45621 45645 45648 45655 45695 45698 45728 45760 45770 45774 45795 45811 45875 45957 46000 46157 46174 46175 46183 46214 46226 46337 46342 46369 47104 47106 47187 47199 47255 47268 47277https://cdsarc.cds.unistra.fr/viz-bin/moc/VIII/45?format=asciiRadiodefaultVIII/45/table2Radio and optical identificationsrecnoRecord number assigned by the VizieR team.
