Compilation of mass accretion rates vs. stellar masses measured from VLT/X-shooter spectra by Alcalá et al. (2014, 2017, green squares, Lupus sample) and by Manara et al. (2016, 2017, red stars, Chamaeleon I sample). The red solid and dashed lines show the values of mass accretion rates corresponding to objects whose accretion luminosity is respectively equal to the stellar luminosity or to 10% of it. The limits derived here due to chromospheric emission are shown with green and blue dotted lines for ~3 Myr and ~10 Myr old objects, respectively.
