Caption: Fig. 8.

Line profiles of near‐IR emission lines observed with PHOENIX on the KPNO 4 m telescope. The presumed heliocentric radial velocity of +73 km s⁻¹ is shown by the dotted vertical line in each panel. The bottom panel compares near‐IR hydrogen line profiles observed with PHOENIX with the Hα profile of the central star observed with HST/STIS (dashed line).
