Same as in Fig. 22, but for several forbidden iron lines (black, and smoothed in red) instead of He Iλ5876. The velocities are centered on LMC rest frame velocities of [Fe II] λ5159 (upper left panel), [Fe III] λ5270 (lower left), [Fe V] λ4227 (upper right), and [Fe VII] λ721 (lower right). In each panel gray arrows mark velocities for other nebular lines seen in SNRs (Fesen & Hurford 1996). In particular, [Fe II] λ5159 could be blended with (and even dominated by) [Fe VII] λ5159. We note broad wings of [Fe V] λ4227, possibly reaching ± 2000 km s−1.
