VizieR Online Data Catalog: M Dwarf catalog of LAMOST DR1 (Guo+, 2015)
Abstract
We present a spectroscopic M dwarf catalog from LAMOST DR1, which consists of 110321 M dwarf spectra of 93619 objects. Our catalog not only includes the spectral subtypes, RVs, EWs of Hα, magnetic activity, nine molecular band indices and their errors, and metal-sensitive parameter {zeta}, but also provides 2MASS photometric information. Their distances and space motions (U, V, W) are also available for high S/N objects.
Using a sample of more than 120000 candidates from the LAMOST spectroscopic database, we combine the 2MASS infrared photometry and CaH/TiO5 ratio to eliminate possible M giant contamination. By examining the distributions of S/N, magnitude and spectral subtype, as well as RV, we gain an overall understanding of M dwarfs in LAMOST DR1. (1 data file).- Publication:
