Caption: Figure 9.
Wind profiles from lines of Si II (co-added), C II (co-added), Si III λ1206.5, and He I λ10830 (colors), normalized to the surrounding continuum. Each profile includes a co-added profile (thin black spectrum) that combines the Si II and C II lines to help guide the eye. Narrow absorption features near 0 km s−1 trace either interstellar or circumstellar material. All co-added profiles are combined in flux space.
