Abstract
We report the results of a 1.2 mm 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() line survey of Bronfman et al. ([CITE]). Regions of , centered on each IRAS source, were mapped with an angular resolution of ~24´´, using the SIMBA array on the SEST telescope. 1.2 mm emission was detected toward all IRAS sources. We find that the dust cores associated with these sources have typical sizes of 0.4 pc and masses of . Dust temperatures and luminosities, derived from the SED, are typically 32 K and .
