Fig. 1
Model fits for a SDSS/SEGUE star, SDSS J093339.24+310245.4, with the mean S/N of the sample, ~40. The three panels in the left column correspond to the fit regions from which the [Fe/H] abundance was determined. The derived iron abundance is shown in the legend of the upper panel, while the temperature and surface gravity estimates are shown in the legend of the lower panel. The panels in the right column show the CaII HK doublet and the MgIb triplet that were fit to determine Ca and Mg abundances, with the derived estimates shown in the legends.
