Fig. 3


Montage of the Hα, β and He i 6678 Å line profiles, with the latter two plotted with an arbitrary vertical exaggeration and offset in order to ease comparison to Hα. Note the central component of Hα at projected velocity ~0 km s-1 has a maximum peak intensity of ~6× continuum; we suspect nebular contamination of this feature and the comparable peaks in Hβ and He i 6678 Å.
