VizieR Online Data Catalog: Abundances of red giants in NGC 6218 (Carretta+, 2007)
Abstract
Spectra for 79 RGB stars in NGC 6218 (M 12) were obtained with FLAMES@VLT using two gratings (HR11, HR13). Abundances of Fe, O, Na were derived using equivalent widths, model atmospheres and atmospheric parameters based on photometry. For each star we give identification, equatorial coordinates, VBJK magnitudes, heliocentric radial velocity for both gratings, Teff, logg, [A/H], vt, [Fe/H], [O/Fe], [Na/Fe]. Equivalent widths are given in tablea.
