Accretion luminosity as a function of stellar luminosity for the whole Chamaeleon I sample of Class II discussed here (red filled stars for accreting objects and empty stars for non-accreting objects) and for the Lupus sample of Alcalá et al. (2014), reported with green squares, and with empty green squares for subluminous targets. Symbols for objects in other regions and at other evolutionary stages, such as transitional disks, are reported in the legend. In particular, transitional disks located in the Chamaeleon I region are shown with red empty circles. Dashed lines are for different Lacc/L⋆ ratios in decreasing steps from 1, to 0.1, to 0.01, as labeled. The blue upper limit is a transitional disk.
