$\begin{figure} \par\includegraphics[width=6cm,clip]{2315fig2.eps} \end{figure}$ Figure 2: Comparison of the equivalent widths measured by us and by Tautvaisiené et al. (2004) for the lines in common. Open hexagons refer to Star # 1282, crosses refer to Star # 1665 and asterisks to Star # 1708. The straight line is not a fit, but simply the bisector.

$\begin{figure} \par\includegraphics[width=6cm,clip]{2315fig3.eps} \end{figure}$ Figure 3: Atmospheric models for Star # 1665. All models correspond to $T\rm_{eff }$ = 3945 K log g = 0.80. The solid lines refer to an opacity sampling ATLAS 12 model with abundances as provided in Table 2. The dashed lines refer to an ATLAS 9 model computed with a solar-scaled ODF with [M/H] = -0.5 and a microturbulence of 1 ${\rm km~s}^{-1}$ . The dash-dotted lines refer to the ionization structure of the ATLAS 9 model computed by WIDTH when the abundances of Table 2 are provided as input. The top panel shows the Fe I and Fe II ions, the middle panel the Mg I and Mg II ions, while the bottom panel displays the temperature structure of the model. The neutral ions show a peak in number densities around $\log\tau_{\rm ross}\sim -1.5$ .

$\begin{figure} \par\includegraphics[width=8cm,clip]{2315fig4.ps} \end{figure}$ Figure 4: [ $\alpha$ /Fe] vs. [Fe/H] for the five stars of Terzan 7 (filled dots), the 12 stars in the Sgr dSph main body studied in Paper I (open squares), and the five stars in M 54 from Brown et al. (1999) (open triangles). $\alpha$ is defined as the mean of Mg, Si, and Ca.
