Beginning of ReadMe : J/PASP/113/1365 Super-metal-rich stars (Buzzoni+, 2001) ================================================================================ Lick spectral indices for super-metal-rich stars. Buzzoni A., Chavez M., Malagnini M.L., Morossi C. <Publ. Astron. Soc. Pac. 113, 1365 (2001)> =2001PASP..113.1365B ================================================================================ ADC_Keywords: Abundances, peculiar ; Abundances, [Fe/H] Abstract: We present Lick spectral indices for a complete sample of 139 candidate super-metal-rich stars of different luminosity classes (MK type from I to V). For 91 of these stars we were able to identify, in an accompanying paper, the fundamental atmosphere parameters. This confirms that at least 2/3 of the sample consists of stars with [Fe/H] in excess of +0.1 dex. Optical indices for both observations and fiducial synthetic spectra have been calibrated to the Lick system according to Worthey et al. (1994, Cat. J/ApJS/94/687) and include the FeI indices of Fe5015, Fe5270, and Fe5335 and the MgI and MgH indices of Mg_2_ and Mg_b_ at 5180AA. The internal accuracy of the observations is found to be sigma(Fe5015)=10.32AA, sigma(Fe5270)=10.19AA, sigma(Fe5335)=10.22AA, sigma(Mg_2_)=10.004mag, and sigma(Mg_b_)=10.19AA. This is about a factor of 2 better than the corresponding theoretical indices from the synthetic spectra, the latter being a consequence of the intrinsic limitations in the input physics, as discussed by Chavez et al. (1997, Cat. J/A+AS/126/267).
