Table A.10.
Uncertainties in the derived Mg, Si, Ca, and Ti abundances from each individual line arising from typical uncertainties of ± 100 K in Teff, ±0.2 dex in log g, ±0.1 dex in [Fe/H], and ±0.1 km/s in ξmicro. We selected seven stars with metallicities covering the range explored in this study (metallicities are mentioned in brackets below the name of each star). The abundance uncertainty, i.e., the dispersion estimated from the Gaussian fit to the distribution of 50 abundance estimates (estimated using 50 sets of stellar parameters) from each line is listed in each column. The mean uncertainty based on the error propagation is listed in the row after each element.
