Accretion luminosity as a function of the stellar luminosity for class II, EV, and TD disks, as labeled. The dashed lines show L_acc/L_star = 0.001, 0.01, and 0.1, respectively. The crosses surronded by a circle are the class II stars included here from the Gatti et al. (2008) sample, and listed in Table 3. Different colors for lower and upper limits can be distinguished in the online version of the journal.
