Caption: Figure 9.

Top (bottom) row of the figure corresponds to the LMC (SMC). The left column shows the mean metallicity per pixel. The same general features are seen as in Figure 8, with the central regions of both Clouds being the most metal-rich and diffuse metal-enhanced structures seen in the outer LMC disk. The middle column shows the stellar density map of the Clouds; central regions of high extinction are most affected, yielding gaps in the density profile. The SMC displays a stretched morphology with wings on the eastern and western sides of the dwarf, a consequence of the tidal interactions with the LMC. The right columns show the extinction map adopted in this work. Generally, the extinction is low aside from the eastern side of the LMC lying nearest the Galactic plane and various filamentary structures throughout it. Stars that fall between the dashed (dotted) lines are those shown in Figure 11 to trace the metallicity profile of the LMC and SMC along the projected major and minor axes of their respective bars.
