Spectra at 1.6″ and 2.4″ from the central object for all unidentified emission features. Dashed lines indicate the best-fit peak position for each feature. Top left: λλ5800, 5827, and 5854. Top right: λ6617. Bottom left: λ8692. In all features except λ8692, a blueshift with increasing distance from the central object is observed. The λ8692 feature shifts towards longer wavelengths in the spectra shown here, but it shifts towards shorter wavelengths on the other side of the star. The 1.6″ spectrum of λ8692 has been stretched by a factor 8 for displaying purposes.
