These regions have previously been identified as harbouring a methanol maser and/or a radio continuum source [ultracompact (UC) HII region], the presence of which is in most instances indicative of massive star formation. The 1.2-mm emission was mapped using the SIMBA instrument on the 15-m Swedish ESO Submillimetre Telescope (SEST). Emission is detected toward all of the methanol maser and UC HII regions targeted, as well as towards 20 others lying within the fields mapped, implying that these objects are associated with cold, deeply embedded objects. Interestingly, there are also 20 methanol maser sites and nine UC HII regions within the fields mapped which are devoid of millimetre continuum emission. In addition to the maser and UC HII regions detected, we have also identified 253 other sources within the SIMBA maps. All of these (253) are new sources, detected solely from their millimetre continuum emission. In total, 404 sources are detected, representing four classes of sources which are distinguished by the presence of the different combination of associated tracers.2005MNRAS.363..405Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/363/405CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/114 : MSX6C Infrared Point Source Catalog (Egan+ 2003)J/A+A/417/615 : Maser and outflows in UC HII region (Codella+, 2004)J/ApJS/155/123 : JHKs photometry of ultracompact HII regions (Alvarez+, 2004)J/A+A/336/339 : VLA observations of ultracompact HII regions (Molinari+ 1998)J/A+AS/133/29 : Molecular line survey towards UC HII (Hatchell+ 1998)J/A+AS/115/81 : A CS(2-1) survey of UC HII regions (Bronfman+, 1996)J/ApJS/91/659 : Ultracompact HII regions radio images (Kurtz+ 1994)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/363/405https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/363/405http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/363/405https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/363/405https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/363/405http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/363/405GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/363/405/table5 (Parameters for the 404 1.2-mm continuum sources found in the survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/363/405/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/363/405/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/363/405/table5?GETtext/xml+votable180.050000true85.427917-1.9063890.0055555555555555566/14353 21458 22855 23969 23982 24325 24365 28829-28831 28890 28896 28912-28913 28918-28919 29070 29090-29092 29094 29096-29097 29100-29101 29103 29114-29116 29118 29160 29461 29505 29510-29511 29529 29532-29533 29535 30218-30219 30241 30256 30259 30262-30263 30268-30269 30312-30313 30318-30319 30330 30405 30420 30694 37244 37343 37839 37846 37850 37897 37900 37923-37924 37938 38020 39282 41653 41655 41661 41677 41696 41777 41804 42159 42169 43013 43015 43019 43024 430411.6553710550405622e-22 1.6553710550405622e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/363/405?format=asciiRadiodefaultJ/MNRAS/363/405/table5Parameters for the 404 1.2-mm continuum sources found in the surveySimbadSimbad column added by the CDSmeta.refcharrecnoRecord number assigned by the VizieR team.
