cds-question@unistra.frradio-galaxiesastrometryphotometryIn tablea1.dat, we present the WENSS selected candidate GRGs after removing sources identified as non-GRGs on basis of optical data. In tablea2.dat, we present the log of the spectroscopic observations of GRG andidates in our sample. In tablea3.dat, we present properties of the radio cores and the optical identifications of the spectroscopically observed giant radio sources, and of the confirmed giant sources B1144+352, B1245+676 and B1310+451. We provide the name of the radio source in IAU notation, the observation used to determine the radio core position and its flux density and the radio core position in right ascension and declination, respectively, in B1950.0 coordinates. The radio positions have been obtained by fitting a Gaussian in the radio map. We further provide the integrated flux density at 1.4GHz of the radio core, the position of the optical identification in right ascension and declination, respectively, in B1950.0 coordinates, obtained from fitting a Gaussian in the available optical image and the magnitude of the identification in the red (POSS-E) band of the Palomar survey. The magnitudes for sources weaker than 15.0 have been obtained from the APM catalogue and are estimated to be accurate to 0.5 mag. For brighter sources, we have measured the magnitudes directly from the digitized POSS-I frames using the photometric calibration for stars available from the STScI WWW-pages and through the getimage-2.0 plate retrieval software. Typical uncertainties in these values are estimated to be large, at least 1mag. In tablea4.dat, further radio properties of the sources in tablea3.dat. We present the integrated flux density of the source at 325MHz from the Westerbork Northern Sky Survey (WENSS) (unless stated otherwise), the integrated flux density at 1400MHz from the NVSS, the spectral index between 325 and 1400MHz, the redshift of the host galaxy, the angular size of the radio source in arcminutes, the resulting projected linear size in Mpc (using H_0=50km/s/Mpc, q_0_=0.5) and the radio luminosity at an emitted frequency of 325MHz.2001A&A...374..861Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/374/861CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/374/861https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/374/861http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/374/861https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/374/861https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/374/861http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/374/861GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/374/861/tablea1 (WENSS selected candidate GRGs after removing sources identified as non-GRGs on basis of optical data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/374/861/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/374/861/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/374/861/tablea1?GETtext/xml+votable180.050000true0.9343934.495010.005555555555555556Cone search capability for table J/A+A/374/861/tablea3 (Properties of the radio cores and optical identifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/374/861/tablea3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/374/861/tablea3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/374/861/tablea3?GETtext/xml+votable180.050000true33.564068632.85148770.0055555555555555566/1130 1546 2143 2296 2313 2331 2507 2660 2669 2816 3538 3698 3833 3980 4086 4965 5012 5075 5081 5118 5180 5313 5388 5438 5785 5916 6058 6385 6407 6507 6576-6577 6598 6628 6683 6749 6764 6956 7049 7147 7237 7301 7455 7661 7907 7920 7965 8042 8065 8080 9053 9118 9123 9162-9163 9413 9539 9698 9812 9941 10031 10137 10455 10458 10463 10534 10548 10657 10680 10847 10874 10919 11151 11241 11254 11648 11889 11905 11931 12223 12250 13510 13556 13629 13760 13858 13891 14508 15113 15130 15140-15141 15157 15216 15237 16014 16036 16095 16327 20305 20397 20429 20479 28567 286432.1534725313611987e-25 9.276497240453405e-25https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/374/861?format=asciiOpticalRadiodefaultJ/A+A/374/861/tablea4Radio properties of the sourcesrecnoRecord number assigned by the VizieR team.
