SpT and T_eff depedency of the accretion noise log(L_acc, noise/L_⋆) values obtained from interpreting the uncertainties in the Balmer and Paschen continuum (< 500 nm) on our model class III spectra as accretion (green dots). The blue dots illustrate the log(L_acc, noise/L_⋆) values obtained when fitting the class III spectra with an accretion slab model. The results obtained for the PENELLOPE Chamaeleon I sample is indicated with orange dots. The black line shows the L_acc, noise relationship measured from the emission lines by MFA17 and the red lines on the left show the uncertainty thereon. On the right, the red line illustrates the best fit to the log(L_acc, noise/L_⋆) values.
