Accretion luminosity as a function of stellar luminosity (left column) and mass accretion rate as a function of stellar mass (right column) for the Taurus sample (large circles). In the top panels the symbols are distinguished according to the disk structure and in the lower panels the symbols are allotted according to the multiplicity. The bottom panels provide a comparison with Lupus (blue) and Chamaeleon I (magenta). Solid lines are the best fit to data of the same color. The average errors for the Taurus sample are drawn in the lower corner.
