Re:NGC 3884
NGC 3884.--The extended tail of faint emission redward of [N II] 6583 betrays a
hidden broad-line component in NGC 3884 (Keel 1983; Paper I; Fig. 10f).
Unfortunately, the high recession velocity of the object shifted part of the
[S II] {lambda}6731 line out of our spectral range. The narrow-line model
profile, derived solely from [S II] {lambda}6716, is therefore not well
constrained. In particular, we could not verify whether the extended tail of
emission is truly absent from the [S II] lines. Nevertheless, neither [O I]
nor [O III] shows any obvious signs of such extreme red asymmetry in their
profiles, leading us to conclude that the deduced broad H{alpha} component is
very likely to be real.
