Correlations between the accretion luminosity (L_acc) obtained from the UV excess fitting (slab-modeling) and the wing (left) and core (right) components fluxes (Alcalá et al. 2017). The black line shows the Y = X curve. The average accretion luminosity derived from the wing components of various lines is correlated with the accretion luminosity derived from that of slab-modeling (Sect. 5.3), while the accretion luminosity derived from the core component is well above it.
