VizieR Online Data Catalog: LAMOST Quasar Survey: quasar properties from DR2&3 (Dong+, 2018)

The Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) Quasar Survey is conducted under the LAMOST ExtraGAlactic Survey (LEGAS; Zhao et al. 2012RAA....12..723Z). Its quasar candidates are selected based on multi-color photometry and data-mining. The regular survey began in 2012 September and will continue for the next five to six years. This paper is the second installment in the series of LAMOST quasar survey, after the pilot observations (Wu et al. 2010RAA....10..737W, 2010RAA....10..745W) and data release one (Ai et al. 2016, J/AJ/151/24, Paper I). Here, we report LAMOST quasar survey data releases two and three, which include quasars observed between 2013 September and 2015 June. The LAMOST, also known as Guoshoujing Telescope, is a 4 m reflecting Schmidt telescope located at Xinglong Observatory, China (Cui et al. 2012RAA....12.1197C; Zhao et al. 2012RAA....12..723Z). It is equipped with 4000 fibers across a 5° field of view. LAMOST has two sets of spectrographs. The blue channel covers the spectrum from 3700 to 5900Å, while the red channel covers the spectrum from 5700 to 9000Å. The spectral resolution R is about 1800 over the entire wavelength range.
