本文报道了用哈佛-史密森1.2米毫米波望远镜对12CO的J=1→0谱线上的猎户座-独角星云复合体进行的新的大尺度测量结果。这项调查由52 288个均匀分布的光谱组成，覆盖了天空432度2的区域，是迄今为止对该区域进行的最敏感的大规模调查。从对前景和背景恒星的分析中估计的到该复合体组成分子云的距离，提供了关于整个复合体的三维结构的信息。
We report the results of a new large scale survey of the Orion-Monoceros complex of molecular clouds made in the J = 1 → 0 line of 12 CO with the Harvard-Smithsonian 1.2 m millimetre-wave telescope. The survey consists of 52 288 uniformly spaced spectra that cover an area of 432 deg 2 on the sky and represent the most sensitive large-scale survey of the region to date. Distances to the constituent molecular clouds of the complex, estimated from an analysis of foreground and background stars, have provided information on the three dimensional structure of the entire complex.
