摘要:We present results from two different procedures for estimation of metallicities ([Fe/H]) and
carbon abundance ratios ([C/Fe]) based on a sample of 582 calibration stars of known
composition. This sample is much larger that used by Rossi et al. (2005), due to the dramatic
increase in the number of stars with elemental abundances measurements obtained from highresolution
analyses in the past few years. This work also compares results obtained from a new
calibration on the KP and GP indices with that obtained from a custom set of spectral synthesis
based on MOOG.
