cds-question@unistra.frh-ii-regionsmillimeter-astronomysubmillimeter-astronomyWe present a SCUBA submillimetre (450 and 850{mu}m) survey of the environment of 105 IRAS point sources, selected from the Wood and Churchwell (1989ApJS...69..831W) and Kurtz et al. (1994, Cat. J/ApJS/91/659) radio ultracompact (UC) HII region surveys. We detected a total of 155 sub-mm clumps associated with the IRAS point sources and identified three distinct types of object: ultracompact cm-wave sources that are not associated with any sub-mm emission (sub-mm quiet objects), sub-mm clumps that are associated with ultracompact cm-wave sources (radio-loud clumps); and sub-mm clumps that are not associated with any known ultracompact cm-wave sources (radio-quiet clumps). 90% of the sample of IRAS point sources were found to be associated with strong sub-mm emission. We consider the sub-mm colours, morphologies and distance-scaled fluxes of the sample of sub-mm clumps and show that the sub-mm quiet objects are unlikely to represent embedded UC HII regions unless they are located at large heliocentric distances.2006A&A...453.1003Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/453/1003CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/91/659 : Ultracompact HII regions radio images (Kurtz+ 1994)J/A+A/336/339 : VLA observations of UC HII regions (Molinari+ 1998)J/A+AS/133/29 : Molecular line survey towards UC HII (Hatchell+ 1998)J/A+AS/120/283 : Water maser features in UC HII regions (Hofner+ 1996)J/ApJS/155/123 : JHKs photometry of UC HII regions (Alvarez+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/453/1003https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/453/1003http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/453/1003https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/453/1003https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/453/1003http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/453/1003GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/453/1003/table1 (UC HII fields observed during the survey, their central coordinates and estimated distance to the UC HIIs in each field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/453/1003/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/453/1003/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/453/1003/table1?GETtext/xml+votable180.050000true267.170833-28.0284440.005555555555555556Cone search capability for table J/A+A/453/1003/table2 (Identifications, coordinates, peak and integrated fluxes of each submillimetre source detected in the survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/453/1003/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/453/1003/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/453/1003/table2?GETtext/xml+votable180.050000true267.17375-28.030.0055555555555555566/3290 3649 14309 14311 14594 14621-14622 14624 14666 14670-14671 14691 14696 15667 15681 15683 21456 24325 28831 28890 28900 28912-28913 28918-28919 29070 29090-29091 29094 29096 29101 29114 29116 29505 29508 29510-29511 29528 29532-29533 29535 30218-30219 30241 30244-30245 30256 30258-30259 30262-30263 30269 30312-30313 30315 30318-30319 30405 30417 30420 30423 30595 30604-30605 30607 30616 30618-30619 30622 30644https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/453/1003?format=asciiRadiodefaultJ/A+A/453/1003/table1UC HII fields observed during the survey, their central coordinates and estimated distance to the UC HIIs in each fieldrecnoRecord number assigned by the VizieR team.
