The clusters have also been surveyed at 0.843GHz with the Molonglo Observatory Synthesis Telescope (MOST). We have listed a complete 1.38-GHz sample of 149 radio sources within the Abell circles centred on their X-ray centroids. We compare their identification fractions, emitted 1.38-GHz and optical powers, radio spectral indices and radial variation in projected source density with those of the radio-selected samples of Slee et al. (1998AuJPh..51..971S). We compare our fractional radio luminosity function with that of the radio-selected samples of Ledlow and Owen (1996AJ....112....9L) and Slee et al. (1998AuJPh..51..971S). Three significant differences are noted between X-ray and radio-selected samples of clusters; (1) the X-ray sample has an excess of flat-spectrum radio sources; (2) the fractional radio luminosity function for the FR I sources in the X-ray selected sample is much steeper, implying that fewer of their cluster galaxies become hosts for the stronger FR I radio galaxies; (3) a complete absence of FR II radio galaxies in the X-ray selected sample. The average excess projected density of radio sources near our cluster centres is approx. 5 times the background source density.2008MNRAS.391..297Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/391/297CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/391/297https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/391/297http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/391/297https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/391/297https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/391/297http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/391/297GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/391/297/tablea1 (Radio sources detected in the seven cluster fields)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/391/297/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/391/297/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/391/297/tablea1?GETtext/xml+votable180.050000true3.290375-65.90138890.0055555555555555566/32907-32908 32910 33180-33182 33224-33225 33449 33451 33614-33615 45542-45543 46255 46597https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/391/297?format=asciiOpticalRadiodefaultJ/MNRAS/391/297/tablea1Radio sources detected in the seven cluster fieldsrecnoRecord number assigned by the VizieR team.
