Bolometric luminosity ﹩L_{( \mathrm{IR}\,+\mathrm{UV}\,) }﹩ calculated from the extinction‐corrected Hα SFRs, as described in the text vs. velocity dispersion, compared with the model of Murray et al. (2005) for gas fractions ﹩f_{g}=1.0﹩, 0.1, and 0.01 (solid, dashed, and dotted lines, respectively). These three lines also indicate reasonable uncertainties in the model. The local Faber‐Jackson relation is shown by the dot‐dashed line at right. Typical uncertainties are shown by the error bars in the lower right corner.
