cds-question@unistra.frinfrared-sourcesh-ii-regionsWe report the results of a 1.2mm continuum emission survey toward 146 IRAS sources thought to harbour high-mass star forming regions. The sources have FIR colors typical of UCHII regions and were detected in the CS (2-1) line survey of Bronfman et al. (1996, Cat. J/A+AS/115/81). Regions of 15'x10', centered on each IRAS source, were mapped with an angular resolution of ~24", using the SIMBA array on the SEST telescope. 1.2mm emission was detected toward all IRAS sources. We find that the dust cores associated with these sources have typical sizes of 0.4pc and masses of 5x10^3^M_{sun}. Dust temperatures and luminosities, derived from the SED, are typically 32K and 2.3x10^5^L_{sun}_.2004A&A...426...97Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/426/97CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/91/659 : Ultracompact HII regions radio images (Kurtz+ 1994)J/A+AS/115/81 : A CS(2-1) survey of UC HII regions (Bronfman+, 1996)J/A+AS/120/283 : Water maser features in UCHII regions (Hofner+ 1996)J/MNRAS/291/261 : Methanol maser of IRAS-selected sources (Walsh+ 1997)J/MNRAS/301/640 : Ultracompact H II regions studies.
