Top: the [Ne II] line profile on the E edge of the SE emission region and just off the emission region, with the best fit to the latter. X-axis units are km s⁻¹ and Y-axis units are erg(s cm⁻¹ cm² sr)⁻¹. Bottom: channel maps labeled by velocity over the velocity region of the 873 km s⁻¹ feature. Contours are ﹩{2}^{n/2}\times 7\times {10}^{-3}\;\mathrm{erg}{({\rm{s}}\;{\mathrm{cm}}^{-1}\;{\mathrm{cm}}^{2}\;\mathrm{sr})}^{-1}.﹩ The spacing between channels is one velocity pixel or one-fourth of a velocity resolution element.
