See text for a general description of the figure. NGC 4676B: S/N of HST/STIS spectrum is generally low, and the quality of the fitting could be hampered. Both this and the wavelength range starting at 6340 Å make the [O I] lines not visible, so only the S-method could be applied. The fit slightly improves by adding a broad component. There is no Palomar spectrum for this galaxy. The PA is not indicated, as this galaxy belongs to an interacting system, and there is no clear determination of it.
