我结合了大空域多目标光纤光谱望远镜（LAMOST）数据发布6低分辨率光谱调查A， F， G和K型恒星参数目录中的重复光谱恒星参数估计。结合重复测量结果，光谱恒星参数估计的精度提高了两倍。此外，这简化了与其他目录执行基于坐标的交叉匹配的过程。同样，我结合了Xiang等人使用LAMOST数据发布5低分辨率光谱调查数据生成的星表的重复恒星丰度估计。这些数据在恒星、星系和系外行星天文学中有许多应用。我生成的目录可以在https://doi.org/10.7281/T1/QISGRU上作为机器可读的表获得。
I combine duplicate spectroscopic stellar parameter estimates in the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Data Release 6 Low Resolution Spectral Survey A, F, G, and K Type stellar parameter catalog. Combining repeat measurements results in a factor of two improvement in the precision of the spectroscopic stellar parameter estimates. Moreover, this trivializes the process of performing coordinate-based cross-matching with other catalogs. Similarly, I combine duplicate stellar abundance estimates for the Xiang et al. catalog which was produced using LAMOST Data Release 5 Low Resolution Spectral Survey data. These data have numerous applications in stellar, galactic, and exoplanet astronomy. The catalogs I produce are available as machine-readable tables at https://doi.org/10.7281/T1/QISGRU.
