Comparison of [N II] 6548 Å (dash), He II 4686 Å (solid), and He I 5875 Å (dot-dash) profiles on JD 55  370, near the end of the NOT sequence. The resolved peaks are due to the ionized region in the Mira wind and the extended wind is from the shock. The profiles have been scaled in intensity for comparison (see discussion).
