摘要：

金牛座分子云的FCRAO巡天观测到12 CO和13 CO J=1-0的发射，来自这个重要的附近恒星形成区域的98平方度。这组45”分辨率的数据包括迄今为止构建的单个分子云的最高空间动态范围图像，并为分子气体分布，运动学和恒星形成过程提供了有价值的见解。在这篇文章中，我们描述了观测，校准，数据处理，和特性的噪声和线发射的调查。给出了1 km/s速度范围内12 CO和13 CO发射的角分布和云的全速范围。这揭示了一种复杂的、动态的冷分子气体介质。

英文摘要：

The FCRAO Survey of the Taurus Molecular Cloud observed the 12CO and 13CO J=1-0 emission from 98 square degrees of this important, nearby star forming region. This set of data with 45" resolution comprises the highest spatial dynamic range image of an individual molecular cloud constructed to date, and provides valuable insights to the molecular gas distribution, kinematics, and the star formation process. In this contribution, we describe the observations, calibration, data processing, and characteristics of the noise and line emission of the survey. The angular distribution of 12CO and 13CO emission over 1 km/s velocity intervals and the full velocity extent of the cloud are presented. These reveal a complex, dynamic medium of cold, molecular gas.
