Narrowband images of the [O IV] 25.89 μm, [Ne III] 15.56 μm, [Si II] 34.82 μm, [Ne V] 24.32 μm, and [S III] 18.71 μm lines produced from the Spitzer IRS spectral cubes (data originally presented in Ghavamian et al. 2012). The black radio contours from the PWN are overlaid. Velocity shifts of the emission lines and their uncertainties are plotted on the images (redshifted centroids in red and blueshifted ones in blue). The yellow rectangles are the extraction regions for the spectral line measurements listed in Table 3.
