哥伦比亚1.2米望远镜上使用了一种噪声温度极低的新型SIS接收器，实现了全采样快速测绘CO。给出了一次测量的结果，该望远镜的角分辨率降至0.5度，允许在四个月内完成对整个750平方度区域的观测，同时保持足够的分辨率来查看重要的子结构。大多数发射位置在金牛-金牛座暗星云中，这是一个与IC348和NGC1333有关的云，也是一个与加利福尼亚星云(NGC1499)和NGC1579有关的云，它与北部的金牛座-金牛座星云重叠，但在速度上与它们分开。在金牛座西南方向的银河系纬度-25度到-35度，以及南部的L1558和L1551云层中也可以看到几个小云团。参考文献89篇。
A new SIS receiver with extremely low noise temperature, used on the Columbia 1.2-m telescope has permitted mapping CO rapidly with full sampling. Results are presented of a survey for which the angular resolution of the telescope was reduced to 0.5 deg, allowing the observations for the complete region of 750 square degrees to be finished within four months, while retaining sufficient resolution to see significant substructure. Most positions with emission are in the Taurus-Auriga dark nebulae, a cloud associated with IC 348 and NGC 1333, and a cloud associated with the California nebula (NGC 1499) and NGC 1579, which overlaps the northern Taurus-Auriga nebulae but is separated from them in velocity. Also seen were several small clouds at Galactic latitude -25 deg to -35 deg southwest of the Taurus clouds, and the L1558 and L1551 clouds in the south. 89 references.
