Three-mm Ultimate Mopra Milky Way Survey (ThrUMMS) DR6

Data Release 6 of ThrUMMS consists of complete data cubes and various moments of line emission (12CO, 13CO, C18O) from molecular clouds, across 60d×2d of the Fourth Quadrant of the Milky Way at a resolution of 72" in (l,b) and 0.09 km s−1 in VLSR.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.

ThrUMMS第6版数据发布包含覆盖银河系银道第四象限60°×2°天区的分子云完整数据立方体，以及12CO、13CO、C18O三条分子谱线发射的各类矩量图；该数据集在银经（l）与银纬（b）方向的空间分辨率为72角秒，本地静止标准坐标系（Velocity of the Local Standard of Rest, VLSR）下的速度分辨率为0.09 km s⁻¹。
本数据集及相关服务由IPAC下属的红外科学档案馆（Infrared Science Archive, IRSA）对外发布；该档案馆由加州理工学院受美国国家航空航天局（National Aeronautics and Space Administration, NASA）合同委托运营。
