LAMOST第二次巡天数据发布（DR2）包括有先导巡天和前两年巡天的光谱数据，观测时间自2011年10月24日开始，到2014年6月5日结束，共观测1934个天区，获得3,274,369条信噪比大于10的恒星光谱。DR2共释放光谱数共计4,132,782，其中还包括220万颗恒星光谱参数星表。
The Second Data Release (DR2) of the LAMOST Survey encompasses spectroscopic data from both the pilot survey and the first two years of the formal survey. The observational campaign ran from October 24, 2011 to June 5, 2014, during which a total of 1934 sky fields were observed, generating 3,274,369 stellar spectra with a signal-to-noise ratio (SNR) greater than 10. The total number of spectra released in DR2 reaches 4,132,782, which also includes a stellar spectral parameter catalog covering 2.2 million stars.
