850um observations of W3 giant molecular cloud

We have surveyed a ~0.9 square degree area of the W3 giant molecular cloud (GMC) and star-forming region in the 850-um continuum, using the Submillimetre Common-User Bolometer...我们依托亚毫米公共用户测辐射热计（Submillimetre Common-User Bolometer），在850微米连续谱（850-um continuum）波段下，对W3巨分子云（Giant Molecular Cloud，GMC）及恒星形成区的约0.9平方度天区开展了巡天观测。
