log (L_acc,noise/L_⊙) obtained using different accretion tracers and the relations between L_line and L_acc from Alcalá et al. (in prep.). The mean values obtained using the Balmer and HeI_λ587.6 lines are shown with the blue solid lines, and the 1σ dispersion is reported with the blue dashed lines. Upper limits are reported with red empty triangles. The 10% Hα width is reported with a blue filled circle.
