LAMOST光谱巡天第十四次数据发布第〇版 第一批数据

LAMOST第十四次巡天数据发布第〇版第一批（LAMOST DR14 V0 Q1 ），释放了 2025年09月24日到2025年12月31日之间获取的光谱数据，这是LAMOST 第三期光谱巡天获取的数据，包括低分辨率光谱和中分辨率光谱两部分。其中低分辨率观测了146个天区，中分辨率观测了191个天区。共释放低分辨率光谱数 386,029条，其中包括375,255恒星、3,080条星系、7,694条类星体。还包括一个有259,878 颗AFGK恒星的光谱参数星表。另外，释放中分辨率非时域光谱287,258条，中分辨率时域光谱631,436条，还有314,269个星光谱参数。

LAMOST 14th Data Release Version 0 Batch 1 (LAMOST DR14 V0 Q1) released the spectroscopic data acquired between September 24, 2025 and December 31, 2025, which correspond to data collected during the third phase of the LAMOST spectroscopic survey. The dataset comprises two components: low-resolution spectroscopy (LRS) and medium-resolution spectroscopy (MRS). A total of 146 sky fields were observed for low-resolution observations, while 191 sky fields were covered in medium-resolution observations. In total, 386,029 low-resolution spectra are made public, including 375,255 stellar spectra, 3,080 galaxy spectra, and 7,694 quasar spectra. Additionally, a spectroscopic parameter catalog encompassing 259,878 AFGK-type stars is included in this data release. For the medium-resolution data component, 287,258 non-time-domain medium-resolution spectra, 631,436 time-domain medium-resolution spectra, and 314,269 stellar spectroscopic parameters are released.
