Continue to maintain international leadership! Guo Shoujing Telescope releases spectral data exceeding 30 million pieces.

Today, it was learned from the National Astronomical Observatory of the Chinese Academy of Sciences that as of now, the number of spectra released by the National Key Science and Technology Infrastructure - Guo Shoujing Telescope has exceeded 30 million, continuing to rank first internationally in terms of the number of spectra released by sky survey projects. These spectra have been compiled into the LAMOST DR13 data set, and are officially released to domestic astronomers and international collaborators. It is understood that the observation period of the LAMOST DR13 data set is from October 2011 to June 2025, covering 6961 low-resolution observation areas and 3404 medium-resolution observation areas. The 30.82 million spectra released 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 database of approximately 12.94 million sets of stellar spectral parameters. The total number of spectra and stellar parameter databases released by LAMOST continue to lead internationally.
