Comparison between all accretion indicators listed in Table 6. The red dots are our estimates of the accretion luminosity, the red arrows are the upper limits, the yellow triangles refer to L_acc obtained from the U-band excess emission, which was observed non-simultaneously with the other indicators. The green dashed line is the average L_acc,l computed considering all secondary indicators; the green shaded region is the 1σ uncertainty in the average L_acc,l. The blue line is L_acc,c obtained using the excess continuum emission (dashed blue line for the upper limits).
