Fig. 3
Left panel: comparison of the FWHM of [ N II ] emission line from HST and Palomar spectra. The dashed line is the bisectrix of the plane and the dotted lines enclose a region of ±100 km s-1 centered on the bisectrix. Symbols as in Fig. 2. NGC 4486 falls outside the plotting range. Right panel: stellar velocity dispersion in km s-1versus the FWHM of the [ N II ] emission line. The dashed line corresponds to FWHM[ N II ] = 2.35 × σ⋆.
