cds-question@unistra.frvery-long-baseline-interferometryradio-sourcesWe report results of the first phase of observations with Australia Telescope Compact Array (ATCA) at 5 and 9GHz of the fields around 411 {gamma}-ray sources with declinations less than +10{deg} detected with Fermi but marked as unassociated in the 2FGL catalogue. We have detected 424 sources with flux densities in a range of 2mJy to 6Jy in the fields of 283 {gamma}-ray sources within their position error ellipses drawn to cover the area of 99 per cent probability of their localisation. Of them, 146 objects were detected in both bands. We found 84 sources with spectral index flatter than -0.5 in our sample. The majority of detected sources are weaker than 100 mJy and for this reason were not found in previous surveys. Approximately 1/3 of our sample, 128 objects, have the probability of being associated by more than 10 times than the probability of being a background source found in the vicinity of a {gamma}-ray object by chance. We present the catalogue of positions of these sources, estimates of their flux densities and spectral indices when available.2013MNRAS.432.1294Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/432/1294CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/81 : Sydney University Molonglo Sky Survey (SUMSS V2.1) (Mauch+ 2008)VIII/82 : 2nd Epoch Molonglo Galactic Plane Survey (MGPS-2) (Murphy+, 2007)II/311 : WISE All-Sky Data Release (Cutri+ 2012)J/ApJS/199/31 : Fermi LAT second source catalog (2FGL) (Nolan+, 2012)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/432/1294https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/432/1294http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/432/1294https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/432/1294https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/432/1294http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/432/1294GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/432/1294/tables1 (The catalog of 146 objects detected at both 5 and 9GHz sub-bands)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1294/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1294/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1294/tables1?GETtext/xml+votable180.050000true7.83204177.41494440.005555555555555556Cone search capability for table J/MNRAS/432/1294/tables2 (The catalog of 229 objects detected at 5GHz sub-band only)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1294/tables2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1294/tables2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1294/tables2?GETtext/xml+votable180.050000true3.641-5.21333330.005555555555555556Cone search capability for table J/MNRAS/432/1294/tables3 (The catalog of 49 objects detected only at sidelobes of 5 or 9GHz beam)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/432/1294/tables3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/432/1294/tables3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/432/1294/tables3?GETtext/xml+votable180.050000true21.2603333-23.43136110.0055555555555555566/172 17154 17343 17366 17819 17822 18343 18444 19202 19525 19589 20481 20606 20735 21010 21164 21458 21593 21646-21647 21656 21710 21804 21806 21898 22222 22239 22243-22244 22683 22805 22855 22864 22873 22876 23105 23227 23338 23364 24836 24885 25106 25234 25468 25544 25781 25820 26892 26897 28681 28702 28716 28748 28754 28781 28817 28823 28828 28830 28839 28854 28856 28862 28892 28900 28904 28912 29002 29090 29113 29118 29154 29252 29322 29504 29514 29547 29613 29647 29717 29782 29803 29816 29828 29835 29881 30196 30222 30251-30252 30254 30258-30259 30262-30263 30269 30284 30317 30330 30341 30356 30417 30419-30420 30425 30601 30617 30743 30781 30827 30836 30968 30981 30984 30995 30999 31011 31026 31262 31283 31778 31788 31822 33027-33028 33030 33059 33173 33198 33506 33528 34107 34128 34375 34592 35063 35227 35826 36133 36144 36716 36886 36892 36910 36957 37222 37367 37479 37487 37850 37861-37862 37873 37881 37884 37900 37925 37928 37930 37934 37991 38016 38018 38112 38488 38635 38873 38911 39111 39249 39251 39260 39733 39777 39889 39978 40113 40143 40422 40585 40680 41298 41460 41510 41571 41574 41644 41653-41654 41671 41689 41699 41740 41770 41775 41780 41782 41794 41815 41837 41908 42005 42043 42107 42136 42140 42151 42157 42169-42170 42207 42214-42215 42220 42226 42311 42335 42369 42378-42379 42454 42498 42518 42522 42541 42545 42561 42579 42744 42945 43003 43021 43024 43038 43060 43075 43077 43109 43156 43194 43228 43265 43267 43280 43319 43435 43531 43643 43660 43805 43824 43848 43862 43877 43879 43996 44011 44253 44284 44302 44540 44585 44654 45011 45122 45191 45199 45284 45316 45397 45496 45736 45914 46057 46285 46361 46568-46569 46613 47154 47190 47442 47461 47612 47742 47894 47939 48528 48685 48784 48845 48868 489576.62606957030801e-25 5.963462613277209e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/432/1294?format=asciiRadiodefaultJ/MNRAS/432/1294/tables1The catalog of 146 objects detected at both 5 and 9GHz sub-bandsrecnoRecord number assigned by the VizieR team.
