VizieR Online Data Catalog: Halpha and other EWs of LAMOST M-type stars (Zhang+, 2021)

The Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) (also known as the Guoshoujing telescope) is a reflecting Schmidt optical telescope with a field of view of about 25° and an effective aperture of 3.6-4.9m, which is located at the Xinglong Station of the National Astronomical Observatories of China (NAOC). There are 738477 spectra of 622523 M stars from the LAMOST low-resolution spectra DR7 survey (up to 2019 June).

We have cross-matched the M stars of the LAMOST low-resolution spectral survey with the catalog obtained from the LAMOST medium-resolution (R~7500) spectra survey.
