Fig. 14


Normalised Hα, Hβ, Hδ, and H Pa 14 lines are plotted with φ (clockwise). The line FWHM decreases towards the higher H Balmer series lines. The Hα line wings extend beyond ±300 km   s-1. The higher Balmer series lines also show stronger absorption in the violet line wing to ~300 km   s-1. The Hδ and Pa14 lines (bottom panels) show enhanced blue-shifted absorption around φ = 0.65–0.85, similar to the He i lines.
