Caption: Fig. 5.

IR/1500 Å luminosity ratio plotted vs. the UV color (L2500/L1500 ratio). The symbols are the same as in Fig. 4. The solid curve gives the linear fit [﹩L_{\mathrm{TIR}\,}/ \lambda L_{1500}=-2.42+3.81( L_{2500}/ L_{1500}) ﹩] to the M81 data. The star symbols give the observations for a sample of starburst galaxies, and the dotted line gives the Meurer et al. (1999) relationship determined for starburst galaxies. Representative uncertainties are shown.
