Re-binned IUE FUV spectra of DG Tau with filter transmission curves of the ACS images superimposed (right axis). Strong lines are labeled and the band-passes of the high-resolution spectra are indicated. The filter efficiencies are indicated by the dashed lines (right axis). For comparison, the higher resolution HST STIS spectrum of T Tau is also shown (yellow). The gray-shaded regions indicate strong H₂ lines.
