Fig. 9
FWHM of narrow components fitted to the hydrogen recombination lines. The black line represents the ideal behavior (FWHM(Hα) = 1.0 FWHM(Hβ)). Squares represent galaxies showing departures from this behavior of more than 25%. Circles represent galaxies that comply with this relation within a 25%. a) Results for the HES. b) Results for the 6df survey.
