The positions of the 41 WiFeS fields used for this analysis, overlaid on the SHASSA H |$\alpha$|-emission image for the SMC. The field locations are shown by red points; the coverage of the WiFeS IFU (37 arcsec |$\times$| 25 arcsec) is considerably smaller than these points. The east–west arm is the beginning of the magellanic bridge that links the SMC to the large magellanic cloud.
