Fig. 6


Average accretion luminosity ⟨logLacc(lines)⟩ derived from 15 emission lines as described in the text (upper panel) and the ⟨logLacc(lines)/L⟩ ratio (lower panel) as a function of effective temperature for Lupus and σ-Ori (open stars) YSOs. Plotting symbols for the Lupus YSOs are the same as in Fig. 3. The dashed lines in both panels mark the locus below which chromospheric emission is important in comparison with Lacc. The vertical error bars represent the standard deviation over the average of 15 emission line diagnostics.
