基于CTIO阿格斯多光纤系统的光谱分析，遥远球状星团Reticulum （C0435 -590）和NGC 1841 （C0444-840）的巨星成员的速度和金属丰度表明，这两个星团可能是大麦哲伦星云（LMC）的成员。网带的速度、[Fe/H]金属丰度和绝对星等分别为241.5±1.5 km s−1、−1.71和−6.0±0.2，NGC 1841的速度、[Fe/H]金属丰度和绝对星等分别为212.5±1.8 km s−1、−2.11和−7.9±0.2
Velocities and metallicities for giant star members of the distant globular clusters Reticulum (C0435 -590) and NGC 1841 (C0444-840) based on spectroscopy with the CTIO Argus multi-fiber system show that these two clusters are likely members of the Large Magellanic Cloud (LMC). The velocity, [Fe/H] metallicity, and absolute visual magnitude for Reticulum are 241.5±1.5 km s −1 , −1.71, and −6.0±0,2, and for NGC 1841, 212.5±1.8 km s −1 , −2.11, and −7.9±0.2
