$\begin{figure}\resizebox{8.8cm}{!}{\includegraphics{2982fg19.ps}} \end{figure}$ Figure 19: Positions of the eighteen studied cluster fields (crossed boxes) and of the nineteen additional clusters taken from Piatti et al. (2002b) and Piatti et al. (2005) (triangles) with relation to the SMC bar (straight line) and optical centre (cross). Two ellipses of semi-major axes of 2 $\hbox {$^\circ $ }$ and 4 $\hbox {$^\circ $ }$ (b/a = 1/2), aligned along the SMC Bar, are also drawn.
