$\begin{figure} \par\includegraphics[width=8cm,clip]{2203f1.eps} \end{figure}$ Figure 1: B-band image of NGC 6872. Regions of interest (i.e. high YMC density) are labeled. North is to left, and east is to the bottom. The image is 297'' by 382'' or $\sim$ 18.7 kpc by 24.1 kpc.

$\begin{figure} \par\includegraphics[width=7.5cm,clip]{2203f5.eps} \end{figure}$ Figure 5: Top: colour-colour diagram for sources in NGC 6872, including the tidal tails. Galactic extinction has been removed. The extinction correction vector of $A_{\rm V} = 1$ is shown. Here error refers to the error in the measured colours. SSP model tracks are over-plotted (see text). The numbers along the model tracks refer to the logarithm of the age in years. Middle: colour-colour diagram for the background region in the images. Here the solid line is the stellar model tracks (see text for a description). Bottom: the contour levels of the middle figure subtracted from the top figure (see text for details). Model tracks are the same as in the top panel.

$\begin{figure} \par\includegraphics[width=8.5cm,clip]{2203f9.eps} \end{figure}$ Figure 9: The mass distribution for the young (<10 Myr) clusters. The shaded histogram are clusters that are associated with peaks in the H $\alpha$ intensity image. The dotted vertical line is the completeness limit in the V-band for a 10 Myr old cluster. The dashed line is a fit to the data above the completeness limit of the form $N(m) \propto m^{-\alpha }$ with $\alpha = 1.85$ .

The top panel is the central region of the galaxy (approximately region F in Fig. 3). The bottom left and right panels show the east (regions A, B, and C from Fig. 2) and west (region G from Fig. 4) tails respectively.
