(a) Low‐resolution spectra representing the seven zones outlined in Fig. 1. Fluxes from the larger outer zones are normalized to the area of the ﹩1^{\prime \prime }\times 2^{\prime \prime }﹩ zone at the center. Emission features are seen at 8.6, 11.3, and 12.7 μm, and the rise below 9 μm is the wing of the 7.7 μm feature. (b) Spectra with east and west zones averaged. (c) Zone 1 compared to zone 3 multiplied by 2.1 to equalize the spectra at the peak of the 11.3 μm feature. Note the overall difference in slope of the emission at the two positions.
