NGC 3486 (UGC 6079, 1057+2914) -- There is a weak (f (2300 ~ Å)= 1 ×10-16 erg s-1 cm-2 Å-1 unresolved (FWHM < 0.1") point source in the nucleus of this galaxy, which is a LINER/weak-Seyfert 2 (Ho et al. 1996a). The H flux measured by Ho et al. (1996a) is about 1 × 10-14 erg s-1 cm-2. Using the argument of Maoz et al. (1995) and Maoz (1996) in the cases of other LINERs in the sample, a power-law extrapolation beyond the Lyman limit of the observed UV flux provides enough ionizing photons to explain the observed H flux through photoionization in this object as well. The central point source could therefore be the AGN continuum source.
