Distribution of the equivalent widths of Hα in emission 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). Note the large equivalent widths of Seyfert 1 galaxies. LINERs have equivalent widths that are somewhat smaller than those of H II galaxies, both at low and high infrared luminosities.
