Left: Chandra ACIS-I spectrum of an interior region 39 with the best fit single-component VNEI model (upper diagram, reduced χ² = 2.0 for 103 degrees of freedom) and two-component model (lower diagram, reduced χ² = 1.1 for 100 degrees of freedom). Middle: spectrum of the outermost region 57 in the east (upper) and an interior region 54 (lower) with the best fit 2 VNEI model. The relative flux of the ejecta component (dotted) with respect to the ISM component (dashed) in region 57 is lower than in most other regions. Right: spectrum of region 17 with enhanced Si xiii emission (upper diagram). The Mg xi, Si xiii, and S xv triplets are marked. For comparison, the spectrum of region 08, which is the brightest region in the Lobe next to region 17, is shown (lower diagram). The best fit 2 VNEI model is additionally plotted in the diagrams.
