Distribution of the observed Hα luminosities as a function of the spectral types of the ULIGs in the 1 Jy sample (solid lines) and the BGS LIGs of Veilleux et al. (1995; dashed lines). Seyfert 1 galaxies are very luminous Hα emitters. The LINERs are somewhat underluminous relative to H II and Seyfert 2 galaxies, both at high and low infrared luminosities.
