cds-question@unistra.frastrophysical-masersradio-astronomyradio-sourcesThe Australia Telescope Compact Array (ATCA) has been used to determine positions for many southern methanol maser sites, with accuracy better than 1 arcsec. The results are presented here as a catalogue of more than 350 distinct sites, some of them new discoveries, and many others with positional precision 10-times better than existing published values. Clusters of 2 or 3 sites are occasionally found to account for single previously listed sources. This in turn reveals that the velocity range for each individual site is sometimes smaller than that of the originally tabulated (blended) source. Only a handful of examples then remain with a velocity range of more than 16km/s at a single compact (less than 2 arcsec) site. The precise methanol positions now allow apparent coincidences with OH masers to be confidently accepted or rejected; this has led to the important conclusion that, where a 1665-MHz OH maser lies in a massive star formation region, at more than 80 percent of the OH sites there is a precisely coincident methanol maser. The methanol precision achieved here will also allow clear comparisons with likely associated IR sources when the next generation of far-IR surveys produce precise positions.2009PASA...26..454Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PASA/26.454CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/96 : 6-GHz methanol multibeam maser catalogue (Caswell+, 2010-12)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/PASA/26.454https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/PASA/26.454http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/PASA/26.454https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/PASA/26.454https://vizier.iucaa.in/viz-bin/votable?-source=J/other/PASA/26.454http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/PASA/26.454GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/PASA/26.454/table1 (Positions of methanol masers)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/PASA/26.454/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/PASA/26.454/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/PASA/26.454/table1?GETtext/xml+votable180.050000true92.222166721.64141670.0055555555555555565/7207 10453 10542 10556 6/21458 21510 23764 23969 23982 24325 28808-28809 28812 28817 28824-28825 28827 28874 28896 28900 28912-28913 28918-28919 29090-29092 29094 29096-29097 29100-29101 29103 29112 29115-29116 29504 29510-29511 29529 29532-29533 29535 30218 30256 30595 30600 30618 30644 30694 37343 37846 37850 37886 37893 37897 37923-37924 37938 38020 38024 39251 41597 41599 41653 41655 41676-41678 41681 41683-41685 41688 41696 41758-41759 41765-41767 41770 41772 41777-41778 41780 41804-41805 41817 41820 41824 42159 42172-42173 42207 42210-42211 42214-42217 42228-42230 42378-42379 42383 42387 42390-42391 42393 42396-42398 42417 42436 42438 42441 42444-42445 42448 42450-42451 42454-42457 42460-42462 42496-42498 42502 42515 43013 43015 43019 43021 430244.418263336084788e-24 4.418263336084788e-24https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/PASA/26.454?format=asciiRadiodefaultJ/other/PASA/26.454/table1Positions of methanol masersrecnoRecord number assigned by the VizieR team.
