Today (March 24), reporters learned from the National Astronomical Observatories of the Chinese Academy of Sciences that, as of now, the national major scientific and technological infrastructure—Guo Shoujing Telescope (LAMOST)—has released over 30 million spectra, continuing to hold the position as the astronomical survey project with the most spectra published internationally. These spectra have been compiled into the LAMOST DR13 (v1.0 version) dataset and are officially released to domestic astronomers and international collaborators. It is understood that the observation period for the LAMOST DR13 dataset spans from October 2011 to June 2025, covering 6961 low-resolution observation fields and 3404 medium-resolution observation fields. The released 30.82 million spectra include approximately 13.47 million low-resolution spectra and 17.35 million medium-resolution spectra. In addition, the data released in DR13 also includes a stellar spectral parameter catalog consisting of about 12.94 million groups. The total number of spectra released by LAMOST and the scale of the stellar parameter catalog continue to maintain international leadership. (CCTV News)
